Having an older brother comes with plenty of benefits. Big brothers tend to look out for their younger siblings(兄弟姐妹）,and despite the occasional rocky moment here and there, many siblings enjoy life-long close relationships. However, a new study finds an interesting downside: children with older brothers take longer when it comes to developing language skills.
The study, conducted by a group of researchers in Paris, France, builds upon earlier research that had already established that having older siblings is associated with poor linguistic(语言的）development. Now, researchers say they have come to a more specific conclusion: only children with an older brother exhibit these linguistic difficulties.
One would assume that children with older brothers would grow up around more conversation on a daily basis, thus speeding up their language development. Yet researchers say such children actually take longer than their older brothers to begin developing these skills.
Researchers studied more than 1,000 children from birth to the age of five-and-a-half years old. Each child’s language skills were tested at ages 2,3,and 5.5,using tests specially designed to measure numerous aspects of language development such as vocabulary, syntax, and verbal reasoning.
What the research team discovered was significant: children with an older brother had, on average, a two-month delay in their language development compared to those with an older sister.
As far as explaining this phenomenon, researchers have proposed two hypotheses(假设).The first is that older sisters tend to talk more often than older brothers, which would compensate for parents potentially being less present than they were for their first child. The second hypothesis is that older sisters usually compete with their siblings less than older brothers for their parents’ attention.
As of now, the study’s authors say they can’t say for certain why children with older brothers have a harder time developing language skills. In the future they would like to investigate if culture or location affects the results of these studies.
1.What does the underlined word“downside”in paragraph 1 mean?
A.difficulty B.drawback C.mistake D.burden
2.What does the previous research suggest about older siblings?
A.Having older siblings will affect the younger one’s language development.
B.Many children prefer having brothers and sisters.
C.Older brothers may have something to do with the linguistic difficulties.
D.Children with older siblings would grow up around more conversation.
3.Why do children with older brothers experience the delay in language development?
A.Parents tend to focus more on the first child.
B.Older sisters are more caring than older brothers.
C.Older brothers always seek to get more attention from their parents.
D.Younger children are always ignored by their older brothers.
4.What will further research of the study focus on?
A.The reasons for children’s delay in language development.
B.Other aspects that may influence the outcomes of the study.
C.More assumptions to explain the phenomenon.
D.The effect of culture on children’s language learning.

Seventy years ago I was quite a small little girl, the baby of the family, with an older brother and sister. My father was very ill at the time, and my mother took in sewing of any kind so we could live. She would sew far into the night with nothing but dim gas mantles and an old treadle sewing machine. She never complained even when the fire would be low and the food very scarce. She would sew until the early hours of morning.
Things were very bad that particular winter. Then a letter came from where her sewing machine was purchased, stating that they would have to pick up her machine the next day unless payments were brought up to date. I remember when she read the letter I became frightened; I could picture us starving to death and all sorts of things that could come to a child‘s mind. My mother did not appear to be worried, however, and seemed to be quite calm about the matter. I, on the other hand, cried myself to sleep, wondering what would become of our family. Mother said God would not fail her, that he never had. I couldn‘t see how God was going to help us keep this old sewing machine.
The day the men were to come for our only means of support, there was a knock at the kitchen door. I was frightened as a child would be, for I was sure it was those dreaded men. Instead, a nicely dressed man stood at our door with a darling baby in his arms.
He asked my mother if she was Mrs. Hill. When she said she was, he said, "I‘m in trouble this morning and you have been recommended by the druggist and grocer down the street as an honest and wonderful woman. My wife was rushed to the hospital this morning, and since we have no relatives here, and I must open my dentist office, I have nowhere to leave my baby. Could you possibly take care of her for a few days?" He continued, "I will pay you in advance." With this he took out ten dollars and gave it to my mother.
Mother said, "Yes, yes, I will be glad to do so," and took the baby from his arms. When the man left, Mother turned to me with tears streaming down a face that looked as though a light was shining on it. She said, "I knew God would never let them take away my machine."
1.The turning point in the story may refer to ______.
A. a letter to the family
B. the time when mother comforted me
C. the man’s coming for help
D. the nicely dressed man’s trouble
2.According to the text all the following are true to the man EXCEPT _____.
A. his wife stayed in hospital
B. he was confused when in trouble
C. he had few men to turn to for help
D. he was a dentist
3.What does mother mean by saying “I knew God would never let them take away my machine.?”
A. God can do everything
B. The sewing machine is my only support
C. Everybody should believe in God
D. Never give up when in trouble

Losing weight comes with a lot of health benefits—including making your brain sharper.
Yes, it turns out that overweight may damage cognitive functions (认知功能) such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of
the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.
1.There is less research on overweight and cognitive functions because researchers _____.
A. believe overweight only affects our body
B. have focused on ways to sharpen people’s mind
C. do not consider overweight a main cause for low cognitive ability
D. are clear about the relation between weight and mental functions
2.The result of Gunstad’s study shows that ______.
A. losing weight has little effect on people’s memory
B. losing weight can improve people’s mental functions
C. overweight people are likely to have psychology problems
D. overweight people’s abilities of concentration differ greatly
3.What is Gunstad planning to prove next in his research?
A. Slim people are smarter than overweight people.
B. Healthy diet is better than exercise in losing weight.
C . Traditional ways of losing weight are better than operation.
D. Overweight people will get smarter by taking more exercise.
4.Which of the following is the best title for th e text?
A. Body Weight and Health

I read with interest a recent article on Galactocorp’s planned Shuttlejet flight later this year. I cannot imagine more stupid thing than this, so-called space tourism, and can’t help wondering what on earth humanity is coming to if this can be successful business.
Many may think that space travel is the highest human achievement, which may be the condition when scientific endeavor (努力) is the aim. However, when it comes to space tourism, think we may have found the top of human stupidity. Consider the high cost of getting into space, the billions of dollars wasted on building the Shuttlejet, and the many thousands spent by the passengers—and for what? So that forty fat cats can have a first-class meal along with six minutes of weightlessness, before returning to earth? Never before has so much money been spent for so little benefit (利益). I invite all space tourists to come around to my house. I can treat them to a big dinner and they can have jump on the trampoline (蹦床), and they’ll only need to pay me half the price of Galactocorp.
Further, the money can be used in a smarter way. Think of the many worthy causes that would benefit from the money that has been thrown away on this project already. There are many medical programs in those poor countries. A few hundred thousand dollars could make a big difference to the lives of thousands of people. The benefits would last far longer than six minutes.
Not only is the Shuttlejet a terrible waste of money, it’s also a terrible waste of resources (资源). Think about the materials required to build and the things required to drive the Shuttlejet. Do we really want to pollute the environment for such a pointless exercise and waste so much money for such a pointless exercise?
In a word, we all need to come back down to earth and forget this stupid dream of space tourism.
1.What’s the author’s purpose in writing this text?
A.To ask for advice. B.To stop project.
C.To share his idea. D.To express his interest.
2.What offer does the author make in Paragraph 2?
A.Helping the fat cats lose weight.
B.Asking people to have fun in his house.
C.Providing a trampoline for space tourists.
D.Preparing first-class-meal for the forty cats.
3.What is the author’s main idea against space tourism?
A.It costs space tourists a lot of money.
B.It is just a scientific aim.
C.It is bad for the environment.
D.It causes a lot of waste in money and resources.
4.What does the author mean by saying“come back down to earth”in the last paragraph?
A.The project is unrealistic. B.The project is unscientific.
C.The money should be spent on earth. D.Space is nothing compared with earth.

Coming home from school that dark winter day so long ago, I was filled with excitement of having the weekend off. But I was 41 into stillness by what I saw.
