Sharks use their good sense of smell to search for prey（猎物）. But a new study shows that the rising levels of carbon dioxide in the ocean could reduce sharks' ability to find food. It's bad news for a healthy ocean. Sharks are top predators（掠食动物）and are like the ocean's weed controllers.

Dixson works at the Woods Hole Oceanographic Institution in Massachusetts. Her earlier work has shown that clown fish in acidifying（酸化的）water act strangely. "We want to expand this research to sharks .because we know how important it is for sharks to find their food through their sense of smell," said Dixson.

Her team started by placing sharks in each of three different pools for five days. Each pool had a different level of carbon dioxide in it. The first had the same amount as today's ocean water. The second had a level of carbon dioxide that scientists expect to reach by 2050. The third pool had the highest level of carbon dioxide that could develop by the year 2100.

Sharks weren't allowed to eat any food while in the pools. This made sure that they would be hungry. Then, Dixson released the sharks one at a time into a pool with two side-by-side streams of flowing water. In one stream, the researchers pumped water, in which a dead squid had been overnight. This water smelled strongly of the squid. The other stream contained ocean water with no scent（气味）. Because each stream flowed at the same rate and in the same direction, the squid smell stayed in its stream. The sharks could choose to swim in either stream.

Sharks that had been swimming for five days in pools of regular ocean water spent more than 60 percent of their time in the squid-scented stream. The same was true for sharks that had been in water with the carbon dioxide level that could develop by the year 2050. But sharks exposed to the highest level of carbon dioxide spent just 15 percent of their time in the squid-scented stream.

1.Why did the writer mention the sharks smell at the beginning of the passage?

A. Because the writer appreciates their ability to find food.

B. Because the writer considers them dangerous to human beings.

C. Because the writer intends to show how to control weed in the ocean.

D. Because the writer worries about the sharks in the ocean.

2.What is Paragraph 3 mainly about?

A. What the ocean in the future will be like.

B. Who helped Dixson conduct the study.

C. What kinds of pools were used during the study.

D. What the levels of carbon dioxide will be at in the ocean in the future.

3.The researchers pumped water where a dead squid had been overnight to ______.

A. help the sharks look for food

B. test the sharks' sense of smell

C. prove that sharks like eating squids

D. explain why carbon dioxide in the ocean affects sharks

4.What does the underlined sentence in the last paragraph suggest?

A. Sharks like the squid-scented stream better.

B. Sharks like the stream with the high level of carbon dioxide.

C. Sharks spent 15% of their time in the squid-scented stream.

D. The high level of carbon dioxide can affect the sharks ability to smell.

Moving to a new town or even a new neighborhood is stressful at any age, but a new study shows that frequent moves in childhood are related to poorer well-being(幸福) in adulthood, especially among people who are more introverted(内向的) or neurotic(神经症的).

The researchers tested the relationship between the number of childhood moves and well-being in a sample of 7108 American adults who were followed for 10 years.

“We know that children who move frequently are more likely to perform poorly in school and have more behavioral problems,” said the study’s lead author Shigehiro Oishi. “However, the long-term effects of moving on well-being in adulthood have been overlooked by researchers.”

The study’s participants, who were between the ages of 20 and 75, were contacted in 1994 and 1995 and were surveyed again 10 years later. They were asked how many times they had moved as children, as well as about their psychological well-being, personality type and social relationships.

The researchers found that the more times people moved as children, the more likely they were to report lower life satisfaction and psychological well-being at the time they were surveyed. The research also showed that those who moved frequently as children had fewer quality social relationships as adults.

The researchers also looked to see if different personality types affected frequent movers’ well-being. Among introverts, the more moves participants reported as children, the worse off they were as adults. “Moving a lot makes it difficult for people to keep long-term close relationships.” Said Oishi. “This might not be a serious problem for outgoing people who can make friends quickly and easily.”

The findings showed neurotic people who moved frequently reported less life satisfaction and poorer psychological well-being than people who did not move as much and people who were not neurotic. However, the number and quality of neurotic people’s relationships had no effect on their well-being, no matter how often they had moved as children. In the article, Oishi thinks this may be because neurotic people have more negative reactions to stressful life events in general.

“We can guess that moving often creates more stress,” Oishi said. “But we need more research on this link before we can conclude that moving often in childhood can, in fact, be dangerous to your health in the long-term.”

1.What can be learnt about the new study from the passage?

2.What is the purpose of the study?

3.According to Oishi, ________ .

4.The fifth and sixth paragraphs mainly talk about ________ .

5.It can be inferred from the passage that ________ .

A study showed that the experiences children have in their first few years are important . These experiences affect the development of the brain. When children receive more attention, they often have higher IQs. Babies receive information when they see, hear and feel things, which makes connections between different parts of the brain. There are a hundred trillion (万亿) connections in the brain of a three-year-old child.

Researcher Judit Gervain tested how good newborns are at distinguishing different sound patterns. Her researchers produced images of the brains of babies as they heard different sound patterns. For example, one order was mu-ba-ba. This is the pattern “A-B-B". Another order was mu-ba-ge. This is the pattern “A-B-C”. The images showed that the part of the brain responsible for speech was more active during the “A-B-B” pattern. This shows that babies can tell the difference between different patterns. They also were sensitive to where it occurred in the order.

Gervain is excited by these findings because the order of sounds is the building block of words and grammar. “Position is key to language," she says. “If something is at the beginning or at the end, it makes a big difference: ‘John caught the bear.’ is very different from ‘The bear caught John.’ ”

Researchers led by scientist Patricia Kuhl have found that language delivered by televisions, audio books,the Internet, or smartphones－no matter how educational－doesn’t appear to be enough for children’s brain development. They carried out a study of nine-month-old American babies. They expected the first group who’d watched videos in Chinese to show the same kind of learning as the second group who were brought face-to-face with the same sounds. Instead they found a huge difference. The babies in the second group were able to distinguish between similar Chinese sounds as well as native listeners. But the other babies －regardless of whether they had watched the video or listened to the audio－learned nothing.

1.What makes connections in a baby’s brain?

A. Having a higher IQ. B. The connection with other babies.

C. The baby’s early age. D. Experiencing new information.

2.What did Judit Gervain and her team find in the experiment?

A. Word order is relevant to meaning. B. Babies identify different sound patterns.

C. A certain brain region processes language. D. Babies can well understand different words.

3.What does the underlined sentence mean in Paragraph 3?

A. Words have different sounds.

B. Grammar is important in learning languages

C. Different orders have different meanings.

D. Different languages have different grammar.

4.What is the main conclusion from the study led by Patricia Kuhl?

A. Babies shouldn’t watch a lot of television.

B. Social communication improves babies’ brain development.

C. Listening to different languages helps to develop babies’ brain

D. Foreign languages are beneficial to babies’ brain development
