Children who spend more time outdoors may have a lower risk of becoming nearsighted, new research suggests.
In the study, researchers looked at about 1,900 schoolchildren. The scientists found that the kids who had been instructed to spend more time outdoors over three years were 23 percent less likely to develop nearsightedness during this time than those who had not been instructed to spend more time outdoors. Moreover, among the kids who did become nearsighted during the study, the degree to which their eyesight worsened was slightly smaller among those who spent more time outdoors.
The researchers selected six schools and required the children, whose average age was 7 at the start of the study, to attend one additional 60-minute class of outdoor activities during each school day for three years. The parents of these children were also encouraged to engage their children in outdoor activities after school, especially during weekends and holidays. The other half of the children, from another six schools, continued their usual activity patterns. After three years, 30.4 percent of the kids in the intervention(干预) group had become nearsighted, compared with 38.5 percent of the kids in the other group.
It is not clear exactly why spending more time outside would benefit children’s eyesight, the researchers said. However, some research has suggested that the higher levels of light intensity found outdoors may increase the release of the chemical dopamine(多巴胺) of the eye. In turn, dopamine is known to restrain(抑制) the type of growth in the eye that is associated with nearsightedness.
Based on the new results, the researchers recommend that children spend more time outdoors because of the potential benefits to their eyesight. However, it’s important to protect kids’ skin and eyes from UV light, which can be damaging.
1.What did the children in the intervention group do during each school day?
A. Attend an extra class of outdoor activities.
B. Continue to do their usual activities.
C. Spend one hour in doing eye exercises.
D. Participate in outdoor activities with parents.
2.What can be inferred about the chemical dopamine?
A. It can contribute to poor sight.
B. It can damage people’s brain.
C. It is beneficial to eyesight.
D. It means low levels of light intensity.
3.What may be discussed in the following paragraph?
A. How to design outdoor activities for kids.
B. How to prevent kids becoming nearsighted.
C. How to protect kids’ skin and eyes from UV light.
D. How to encourage kids to join in outdoor activities.
4.Which can serve as the best title for the passage?
A. The More Time Outdoors, the Better
B. Kids May See Better if They Play Outside
C. It’s Time to Engage Kids in Outdoor Activities

Children who spend more time reading with their parents have a greater chance of becoming better readers than those who don’t. With the help from their parents, children can learn techniques to improve their reading skills.
“A lot of parents think after their child learns to read, they should stop reading to them,” Donna George said. “They are sadly mistaken.”
George offers her services to parents at the Title I Learning Centers. She said reading aloud to children may be the most valuable thing parents can do. “It is better for children to hear things at a higher level than where they are,” George said. “Parents are their child’s first teacher.” Parents help their children build listening, phonics, comprehension and vocabulary skills when they read aloud to them.
Before parents can identify reading problems, they should escape the enemy —television and limit the time their children spend watching television. George suggested not allowing kids to have a TV in their bedrooms, setting a schedule of when kids can watch or keeping a list of how many programs children watch. Louise Joines said while her 14-year-old daughter and 10-year-old son enjoy reading, the television sometimes becomes a distraction. So she tries to build the situation by suggesting books the entire family will enjoy reading together, like the Harry Potter series.
Parents who do not read themselves should not count on their children being interested in it. If parents would read to their children at least 15 minutes every day, children would not have so many problems in school. It is the parents’ job to help build that desire in their children, and of course to know what kind of books to read is also important.
1.According to George, reading aloud to children_______________.
A. helps them correct mistakes
B. is helpful to their reading
C. is parents’ first duty to their children
D. can get children out of television’s attraction
2.The underlined word “distraction”(in Paragraph 4) means something that_________
A. can improve children’s reading
B. can help children’s right way of reading
C. can make children interested in reading
D. stop children from concentrating on reading
3.Which of the following is important according to the fourth paragraph?
A. Reading skills.
B. Reading speed.
C. Reading materials.
D. Reading environment.
4.If the passage is not completed, which of the following can follow the fifth paragraph?
A. Parents choose reading materials for their children.
B. Advice is given to control their children.
C. What TV programs children can watch during reading.
D. How children improve their reading by themselves.

Children who are spanked (挨打) have lower IQs worldwide, including in the United States. All parents want smart children. Avoiding spanking and correcting misbehavior in other ways can help that happen.
A new research by Professor Murray Straus found that children in the United States who were spanked had lower IQs four years later than those who weren’t spanked. Straus and Mallie Paschall, a senior research scientist, studied nationally examples of 806 children aged 2 to 4, and 704 aged 5 to 9. Both groups were retested four years later.
The IQs of children IQs aged 2 to 4 who weren’t spanked were 5 points higher four year later than the IQs of those who were spanked. The IQs of children aged 5 to 9 who weren’t spanked were 2.8 points higher four years later than the IQs of children at the same age who were spanked. How often parents spanked made a difference. The more spanking, the slower the development of children’s mental ability. But even small amounts of spanking made a difference.
Straus also found a lower national average IQ in nations in which spanking was more popular. His analysis shows the strongest link between physical punishment and IQ is for those whose parents continue to use physical punishment even when they are teenagers.
Straus also found a lower national average IQ in nations in which spanking was more popular. His analysis shows the strongest link between physical punishment and IQ is for those whose parents continue to use physical punishment even when they are teenagers.
Straus and colleagues in 32 nations used data on physical punishment experienced by 17,404 university students when they were children. According to Straus, there’re two explanations for the relation of physical punishment to lower IQ.
First, physical punishment is extremely stressful and can become a long-lasting stressor for young children, who typically experience punishment three or more times a week. For many it continues for years. The stress of physical punishment often leads to being fearful that terrible things are about to happen and being easily shocked. They’re associated with lower IQ. Second, a higher national level of economic development leads to both fewer parents using physical punishment and a higher national IQ.
The good news is that the use of physical punishment has been decreasing worldwide, which may signal future gains in IQ across the globe. The United Nations has called on all member nations to forbid physical punishment by parents. Nevertheless, there’s evidence that attitude favoring physical punishment and actual use of physical punishment have been declining even in nations which haven’t forbidden physical punishment.
1. From the passage we can know that physical punishment will make______.
A. no scientist
B. a well-behaved child
C. a bad parent-child relationship
D. a child feel nervous continuously
2.It can be concluded from Paragraph 3 and Paragraph 4 that______.
A. long-term spanking will cause children’s mental disorder.
B. low national average IQ limits the mental development of children
C. young children have more chances to suffer from physical punishment.
D. high frequency of spanking results in slow development of children’s intelligence
3. According to Straus’s research, children’s being spanked is probably related to parents’______.
A. low income
B. little education
C. long-lasting pressure
D. passive personalities
4. It can be inferred from the last paragraph that______.
A. the improvement of global average IQ is out of the question
B. physical punishment becomes less popular in the world
C. most countries have realized the negative consequence of punishing in its member nations.
D. the UN has succeeded in banning physical punishment in its member nations

However important we may regard school life to be, there is always the fact that children spend more time at home than in the classroom. Therefore, the teacher should realize that parents have a great influence on their children. Parents can become strong allies (助手) of the school or they can get in the way of the school education.
Experts have realized the need to keep parents informed of the newer methods used in schools. Many headmasters have conducted workshops explaining such matters as the reading readiness, program writing and mathematics to parents.
Moreover, the classroom teacher, with the permission of the supervisors(管理者), can also play an important part in giving more knowledge to reporting pupils progress, teachers can help parents a lot in educating their children and parents can give much help to teachers.
Suppose that a father has been drilling Junior arithmetic lessons night after night. In a friendly talk between the teacher and the father, the teacher can help the parent to make Junior interested in it. He might be persuaded to let Junior join in discussing the family budget, buying the food, using a ruler or measuring cup at home, setting the clock, calculating the distance of a trip and engaging in scores of other activities that have a mathematical basis.
If the father follows the advice, it is reasonable to say that he will soon realize that his son is making satisfactory progress in mathematics, and at the same time, enjoying the work.
Too often, however, teachers’ talks with parents are devoted to small accounts of children’s misdemeanors(不良行为). They talk about the laziness and poor work habits of the children.
What is needed is a more creative way in which the teacher, as an adviser, plants ideas in parents’ minds to make sure that the child spends the many hours out of the classroom learning something useful.
In this way the school and the home join forces in educating children.
1.The main idea of the passage is that ____.
A. home training is more important than school training
B. parents should help their children to do their homework

D. teachers can and should help parents to use better ways to teach their children 2.From this passage we can know that the writer ____.
A. is satisfied with the relationship between school and home
B. feels that parent-teacher talks can be made much more constructive
C. believes that schools can’t teach pupils well
D. calls on parents to teach their children mathematics at home
3.What way that the writer doesn’t talk about can improve the present situation?
A. Classes for parents. B. New type of report card.
C. Parent-teacher talk. D. Dinner or party.
4.The writer implies that ____.
A. interesting activities can improve one’s achievement
B. too many children are lazy and have poor work habits
C. teachers should often make home visits to parents
D. headmasters do more than teachers in this area
5.We can infer from the passage that the writer does not favor ____.
A. father’s helping his son with his study
B. written reports to the parents from the teachers
C. talking about children’s shortcomings
D. having the parents help their children with their lessons
高二英语阅读理解中等难度题查看答案及解析
However important we may regard school life to be, we can’t ignore the fact that children spend more time at home than in the classroom. Therefore the great influence of parents can’t be ignored or discounted by the teacher. They can become strong supports of the school or they can consciously or unconsciously prevent the school from accomplishing its aims.
Administrators have been aware of the need to keep parents apprised of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program and developmental math.
Moreover, the classroom teacher can also play an important role in explaining to parents what they should do. The informal tea and the many interviews carried on during the year, as well as new ways of reporting pupils’ progress, can significantly aid the interchanged of ideas between school and home.
Suppose that a father has been drilling Junior in arithmetic processes night after night. In a friendly interview, the teacher can help the parent change his method. He might be persuaded to let Junior participate in discussing he family budget, buying the food, using a measuring cup at home, setting the clock, calculating mileage on a trip and engaging in scores of other activities that have a mathematical basis.
If the father follows the advice, it is reasonable to assume that he will soon realize his son is making satisfactory progress in math and at the same time, enjoying the work.
Too often, however, teachers’ conferences with parents are devoted to unimportant accounts of children’s wrongdoing, complaints about laziness and poor work habits, and suggestions for punishments and rewards at home.
What is needed is a more creative approach in which the teacher, as a professional advisor, plants ideas in parents’ minds for the best use of the many hours that the child spends out of the classroom. In this way, the school and the home join forces in fostering the fullest development of youngsters’ competence.
1.The underlined phrase “keep parents apprised of” (Line 1, Para. 2) probably means to let parents ________.
A.judge B.know C.design D.develop
2.What is the purpose of the schools’ informal tea and interviews?
A.To improve the relationship between teacher and parents.
B.To explain to parents the change of the school curriculum.
C.To report students’ misdoings and suggestions for punishments.
D.To help develop good communication between school and home.
3.Why does the author provide all example in Paragraph 4?
A.To help parents to know the importance of home activities.
B.To show how the teacher can guide in home training.
C.To prove parents all non professional advisors.
D.To advice parents to teach kids math at home.
4.From the passage we learn that the author________.
A.thinks teachers should do better as professionals
B.is worried about children’s performance at home
C.is satisfied with the present state of school education
D.believes time spent out of the classroom has been wastedw.

Cancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying studies showed a clear link. “Our suggestion is for people to increase their intake (吸入,摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.
Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units(IU)a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.
The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.
“African Americans, who don't produce as much of the vitamin because of their skin colour, could also benefit significantly from a higher intake,” the authors said.
1.According to the passage, people are advised to take more Vitamin D, because__.
A. it is nutritious B. it can’t harm people’s health
C. it can lower cancer risk D. it is not taken enough every day
2.Which of the following can not help people get more Vitamin D?
A. Have some sunshine B. Have more meat
C. Have more fortified cheese D. Have a vitamin supplement
3.Who can Garland probably be?
A. A health researcher B. A doctor
C. A scientist D. A public health official
4.Which of the following food can lower people‘s chance of getting cancer?
A. Milk B. Fortified orange juice
C. Fortified yogurt D. All of the above
5.People from which area should take more Vitamin D according to the passage?
A. Asian people B. African people
C. American people D. European people

Risk of death is 3.5 to 5 times greater for obese (肥胖的) smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 to 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 to 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
Taking Charge of Your Health
Making healthy choices can be difficult when we're constantly exposed to products that are dangerous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart. It's never too late to change your course and even reduce damage to some extent.
1.60. What is the American Journal of Preventive Medicine?
A. An medical institute. B. A research center.
C. A medical magazine D. A TV station
2.Which of the following is true according to the text?
A. Obese smokers are less likely to suffer from cancer.
B. Obese smokers are more likely to suffer from cancer.
C. Obese smokers tend to gain fewer body mass index.
D. Obese smokers tend to get heavier than those who never smoke.
3.According to the author, it is ________ to get rid of smoking.
A. easy and possible B. difficult and impossible
C. easy ant worthwhile D. difficult but worthwhile
4.What is the purpose of the text?
A. To inform the readers of the findings about obese smoking.
B. To warn the readers of the danger of obese smoking.
C. To tell us what obese smoking is.
D. To call on the obese smokers to quit smoking.

Almost two-thirds of children want their parents to spend more time reading to them before bed, and most prefer Mum’s storytelling to Dad’s, researchers said.
They carried out a study that showed younger children aged 3-4 were most hungry for more stories, with over three-quarters saying they wished their parents read to them more often.
More than half of all children aged 3-8 said story time was their favourite pastime with their parents.
"The results of our research confirm the traditional activity of storytelling continues to be a powerful learning and emotional resource in children's lives," said child psychologist Richard Woolfson.
Storytelling ranked higher than television or video games among pastimes for kids, and 82 percent said reading a story with their parents helped them sleep better, according the survey of 500 children aged 3-8 in Britain.
The best storytellers were mothers who used funny voices to illustrate different characters or made their own special sound effects to keep the story moving, researchers said.
When mum and dad are not at hand, celebrities(名人) will do: over 30 percent of children said they would like to hear a bedtime story from Harry Potter star Daniel Radcliffe, with teen idols(偶像) Zac Efron, Miley Cyrus and Emma Watson.
"It can be very difficult for parents to find the time to read with their children, but these moments can help build strong relations and play a vital part in their child's development," said Woolfson.
1.The underlined word “pastime” in the passage most probably means ________.
A.old time B.entertainment C.emotion D.character
2.The author develops the passage mainly by ________.
A.pointing out similarities and differences B.following the natural time order
C.comparing opinions from different fields D.providing examples and statistics
3.Reading a story with their parents helped most kids aged 3-8 ________.
A.grow stronger B.become more emotional C.sleep better D.become more powerful
