A new study has found evidence of aggressive(...

A new study has found evidence of aggressive(富于攻击性的)behaviors in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3, 000 5-year-olds.

Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. The women were also asked to complete a checklist of their children’s behaviors.

The researchers found that 43 percent of the boys and girls drank at least one daily serving of soda, 4 percent of the youngsters had four or more servings of soda to drink every day.

Shakira Suglia is with Columbia University’s Mailman School of Public Health in New York City. She worked on the study with researchers from the University of Vermont and Harvard University School of Public Health. She says they found that children who drank the most soda were more than two times as likely as those who drank no soda to show signs of aggression.

“For the children who consumed four or more servings of soft drinks per day, we see an association between aggressive behaviors, attention problems and withdrawn behaviors. ”

The aggressive behaviors included destroying possessions belonging to others, taking part in fights and physically attacking people.

Doctor Suglia says it’s not clear why young children who drink a lot of soda have behavior problems.

“We can’t prove that this is a direct cause and effect relationship, having said that, there are a lot of ingredients in soda, a lot of ingredients that have not been examined in relation to behaviors. ”

Earlier studies of young adults have found the highest sugar levels in those who carry weapons and show signs of negative social behaviors.

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin caner, actually increases the risk.

Researchers from the University of Yale based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanomas (黑素瘤). They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.

Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (发生率) faster than any other cancer in the United States.

But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.

The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer—people with fair skin and freckles (雀斑), for example—are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often.

The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

1.The underlined word “flaws” in the 2^nd paragraph most probably means ________.

A. evidences             B. facts                C. faults              D. failures

2.People with fair skin and freckles ________.

A. seldom use sunscreen                             B. are more in danger of skin cancer

C. can be free from the harm of the sun              D. often expose themselves to the sun

3.We can learn from the passage that ________.

A. sunscreen users get skin cancer more often

B. the volunteers have proved the effect of sunscreen

C. the new study was based on the experiences of volunteers

D. the number of skin cancer patients is increasing in America

4.Which of the following can be the best title for this passage?

A. Sunscreen to Prevent Skin Cancer

B. Sunscreen to Increase Skin Cancer

C. Skin Cancer Caused by Sunscreen

D. Skin Cancer Caused by Freckles

A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love(早恋) may bring stress for young people and can lead to depression(忧郁症). The study shows that girls become more depressed than boys, and younger girls are the worst of all.

The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study, even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won’t tell that to their parents.

Dr. Marianm Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression.

She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendships and a strong sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.

Parents should watch for signs of depression---eating or mood changes---and if they see signs from their daughter or son, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity(成熟) gives us a chance to avoid its bad side effects.

1.What’s the main idea of the passage?

A．Puppy love may bring young people depression.

B．Parents should forbid their children’s love lives.

C．Romance is a two-edged sword for adults.

D．Romance is good for young people.

2.Which of the following is more likely to have depression?

A．Young people who have a strong sense of self.

B．Young boys whose parents watch for their behavior.

C．Young girls who always hide their feelings and opinions.

D．Careless parents whose children are deep in love.

3.What can be inferred from the passage?

A．Lacking love can lead young people to grow up more quickly.

B．Early love makes young people keep close to their friends and parents.

C．Parents should help their children to be aware of the signs of depression.

D．The older a woman is, the less likely she seems to lose herself in romance.

4.What’s the author’s attitude towards puppy love?

A．Confused.         B．Disapproving.       C．Disinterested.      D．Scared.

A new study, conducted by British company Mindlab International, has found that listening to music at work increases accuracy (精确) and speed, The Telegraph reported.

Perhaps, some parents disagree with this idea, saying, "Switch off the music and concentrate!" Well, if that's the case with your parents, you might now be able to convince them that you have science on your side.

The company gave 26 participants（参与者）a series of different tasks for five days in a row, including spell checking, mathematical word problems, data entry, and abstract reasoning. The participants completed these tasks while listening to music or no music at all.

The results showed that while music was playing, 88% of participants produced their most accurate test results and 81% completed their fastest work. David Lewis, chairman of Mindlab International, told The Telegraph, "Music is a very powerful management tool if you want to increase not only the efficiency of your workforce but also their emotional state... they are going to become more positive about the work."

However, you may have a list of your favorite songs, but not all kinds of music match all homework. For maths or other subjects involving numbers or attention to detail, you should listen to classical music, the study found. In the study, pop music enabled participants to complete their tasks 58% faster than when listening to no music at all. If you are reviewing your English writing, pop music is the best choice, as it is the best kind for spell checking. It cut mistakes by 14%, compared to listening to no music. After finishing your homework, do you often take time to check your answers? Maybe, some dance music is suitable for you.

1.What did the participants have to do in the study？

A. Persuade their parents to listen to music.

B. Do a series of work without rest or pause.

C. Complete five tasks in five days without help.

D. Finish tasks with music or without music at all.

2.What does the underlined word "they" in Para 4 refer to？

A. Results.　　 B. Tools.

C. Participants.　　 D. Tests.

3.What is the best title for the text?

A. Music Helps Us to Learn　　 B. We Can’t Live Without Music

C. Not All Music Suits You　　 D. Listen to Different Music

A new study has found that North American migratory(迁徏的) birds have been getting smaller over the past 40 years. Researchers say the finding suggests a warming climate(气候)could be affecting bird growth in North America -- and across the world.

The study was recently published in Ecology Letters. Researchers measured(测量)the size of 80,000 birds killed from 1978 to 2016 during the spring and fall migrations in the city of Chicago, Illinois. Over the 40-year period, body size decreased in all 52 species. The average body weight fell by 2.6 percent. Leg bone length dropped by 2.4 percent. The one area of growth was the wingspan, which increased by 1.3 percent.

The researchers said the wing growth likely happened to allow the birds to continue making long migrations with smaller bodies. The study considered a principle known as Bergmann’s rule, in which individuals within a species grow smaller in warmer areas and grow larger in colder ones.

Brian Weeks, a biologist at the University of Michigan’s School for Environment and Sustainability, helped lead the research. He said that he believes the results show a clear connection between a warming climate and the growth of the birds. “In other words, climate change seems to be changing both the size and shape of these species,” he said.

The study found a direct connection between the average summer temperature and the body size of the birds. Dave Willard works with Chicago’s Field Museum, which was in charge of measuring all the birds. He said nearly “everyone agrees that the climate is warming, but examples of just how that is affecting the natural world are only now coming to light.”

“We had good reason to expect that increasing temperatures would lead to reductions in body size, based on earlier studies,” Weeks said. “I was incredibly surprised that all of these species are responding in such similar ways.”

The researchers plan to continue studying the Field Museum data in an effort to find additional evidence to support their findings. They will also further examine the idea that an individual’s physical development can change to fit changing environmental conditions.

1.Which of the following didn’t go down to a lower level?

A.The body size B.The body weight

C.The leg bone length D.The wingspan

2.Which of the following took responsibility for measuring the birds?

A.Ecology Letters B.Brian Weeks

C.The Field Museum D.Dave Willard

3.What does the underlined words “coming to light” in Paragraph5 mean?

A.Known B.similar

C.intelligent D.distant

4.The main idea of the passage is that　　　　

A.fifty-two species of birds became smaller.

B.the warming climate could affect bird growth.

C.the warming climate makes the birds grow larger.

D.the researchers have proved their findings.
