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 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 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 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.

1.What’s the main idea of the second paragraph?

A. The aim of the research.

B. The members of the research.

C. The method of the research.

D. The organizer of the research.

2.Which of the following is TRUE about the study?

A. Researchers had face-to-face talks with some children.

B. Mothers played an important part in the study.

C. Half of the children drank one daily serving of soda.

D. The result of the study is unknown.

3.What does the underlined word mean?

A. Bought.　　 B. Drank.　　 C. Fought.　　 D. Studied.

4.What can we learn from Doctor Suglia?

A. The relation between aggressive behaviors and soft drinks is not clear.

B. Children who drink a lot of soda must have behavior problems.

C. There are a lot of ingredients examined in relation to behaviors.

D. Children shouldn’t drink soda.

Dreaming is believing, claim researchers of a new study, who found that dreams have an effect on people’s behavior, judgment and they might contain important hidden truths as well.

“Psychologists’ interpretations (解释) of the meaning of dreams vary widely. But our findings show that people believe their dreams provide meaningful insight (见识) into themselves and their world,” said a lead author of the study Carey More wedge, an assistant professor at Carnegie Mellon University.

In six different studies, researchers surveyed nearly 1,100 people about their dreams. One of the studies focused on general beliefs about dreams and involved 149 university students. All students were asked to rate different theories about dreams. The experts found that a surprising majority of the participants supported the theory about dreams revealing (揭示) the hidden truths about themselves and the rest of the world.

In a second experiment, they surveyed 182 people at a Boston train station, and asked them to imagine one out of four possible situations that could have occurred the night before a scheduled airline trip. Most of the participants said that dreaming of a plane crash would be more likely to affect their travel plans than would just thinking about a crash, or being warned by the government of a terrorism risk. They said a dreamed crash would influence their travel plans just as much as learning about a real crash on their planned route would.

Another experiment involved 270 men and women from across the United States. In a short online survey, they were asked to recall one of the dreams they had seen about any person they knew. The findings showed that people were more likely to remember and describe pleasant dreams about a person they liked, rather than a person they disliked. Meanwhile, in most cases they tended to consider an unpleasant dream as more meaningful if it was about a person they disliked.

“In other words,” said More wedge, “people attribute (归因于) meaning to dreams when it corresponds (与……一致) with their pre-existing beliefs and desires.” The researchers say that more investigation (研究) is needed to fully understand how people interpret their dreams. According to More wedge, most people realize that dreams are not predicting their future, but they still try to find some meaning in there.

1.The purpose of the studies is to _______.

A. determine when people tend to remember their dreams

B. research whether dreams have anything to do with real life

C. find out how people interpret their dreams and what impact that has

D. understand what causes people to dream and how to interpret dreams

2.According to the second experiment, what might influence people’s travel plans most?

A. Thinking about a past plane crash.

B. Dreaming about a plane crash.

C. Hearing a government’s warning of a terrorism risk.

D. Imagining a plane crashing on their planned route.

3.What can be concluded from the study?

A. When a dream conflicts with people’s existing beliefs and desires, they tend to attribute less

meaning to it.

B. Most people disagree that dreams help them better know themselves and the world.

C. A majority of people believes that dreams can predict their future and try to find their meaning.

D. Dreams can be a useful tool for learning and problem solving.

4.Which kind of dream is seen as more meaningful than the rest?

A. A pleasant dream about a person the dreamer likes.

B. A pleasant dream about a person the dreamer dislikes

C. An unpleasant dream about a person the dreamer likes.

D. An unpleasant dream about a person the dreamer dislikes.

If you like texting and are trying to lose weight, a new study found that using texting to track(追踪) diet and exercise habits may help you lose weight.

Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are trying to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.

Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.

The study included 26 obese women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (回复) and tips.

Every morning, the women received a text from an automated(自动的)system that said, “Please text yesterday’s personal information of steps you walked and how many sugary drinks you had.” Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.

After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.

“Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior,” Dori Steinberg, who was responsible for this research, said.

Steinberg said, "Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cellphone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time.”

1.According to the study, traditional methods _________.

A. are easier for people to lose weight

B. may cause people to give up losing weight

C. provide brief feedback and tips

D. are easy to track diet and exercise behavior

2.Which is NOT true about text messaging according to Steinberg?

A. It saves time.

B. It saves money.

C. It can be entered quickly.

D. It is easy to receive feedback.

3.What’s the best title for the text?

A. Texting helps keep healthy

B. Texting saves time and money

C. Texting can help you lose weight

D. Texting provides brief feedback and tips

4.What’s Dori Steinberg’s attitude towards text messaging?

A. Unknown.　　 B. Negative.

C. Positive.　　 D. Unconcerned.
