If you want to improve your child’s results at school, you could do a lot worse than ensuring that they do plenty of exercise. Scientists have already shown that physical activity can make you brainier. But a team in America has used scans to show that an important part of the brain actually grows in children who are fit. These youngsters tend to be more intelligent and have better memories than those who are inactive.
Scientists also found that one of the most important parts of their brains was 12 percent larger than those of unfit children. They believe that encouraging children to take exercise from a very young age could help them do better at school later. Researchers from the University of Illinois, in the U.S., studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan (核磁共振摄影扫描), a technique which provides very detailed pictures of organs and tissues in the body.
They also tested the fitness levels of the children by making them run on a treadmill (跑步机). The scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around 12 percent larger in the fitter children.
Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had important implications for encouraging individuals to take part in sport from a young age. “We knew that experience and environmental factors and socioeconomic status all impact brain development,” he said. “If you get some terrible genes from your parents, you can’t really fix that, and it’s not easy to do something about your economic status. But here’s something that we can do something about.” If you want to improve your children’s result in school, ____________.
| A．it is worse to ensure that they do plenty of exercise |
| B．you can have their brain scanned |
| C．it could be better to make sure that they do a lot of exercise |
| D．you can do a lot except ensuring that they do exercise |
According to the passage, which of the following statements is NOT true?
| A．The fitness level of the children is linked to their intelligence. |
| B．Children who have a larger hippocampus will probably have better memories. |
| C．You can do something about the genes from your parents. |
| D．Unhealthy children will probably have a smaller hippocampus than others. |
All the following factors that have some influence on one’s brain are mentioned EXCEPT ____________.
| A．genetic factor | B．economic status | C．physical fitness | D．economic development |

Students who date(约会) in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia.
“Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships,” said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.
Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.
Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students’ academic(学术的) efforts. He found that some students never or hardly ever reported dating from middle to high school, and these students always had the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.
“At all points in time, teachers considered the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,” according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit (学分), being well organized, finishing homework, working hard and reading assigned chapters.
“Dating a classmate may be as complicated as dating a co-worker,” Orpinas said, “when the couple break up, they have to continue to see each other in class and perhaps see the ex-partner dating someone else. It is reasonable to think this could be linked to depression and could divert (转移) attention from studying.”
“Dating should not be considered a ceremony of growth in middle school,” Orpinas concluded.According to the passage, students who date in middle school may_____
| A．have poorer academic performances |
| B．be more likely to hurt others |
| C．enjoy better school lives |
| D．be less likely to use alcohol and tobacco |
When doing his study, Orpinas ________________.
| A．followed a group of students of 6th and 12th grade |
| B．completed a survey and a report each year |
| C．found that the students’ study skills have connection with their frequency of dating |
| D．completed questionnaires about the students’ academic efforts |
What can possibly happen to the school couples after they break up?
| A．They don’t want to see each other any longer. |
| B．They will think it’s reasonable to get depressed. |
| C．They will miss their ex-partners sometimes. |
| D．Their attention to studying will be affected. |
Orpinas’ attitude towards dating in middle school is_____
| A．supportive | B．negative |
| C．positive | D．Unconcerned |
The weather predictions for Asia in 2050 read like a story from a doomsday movie．
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring．In the decades to come, Asia—home to more than half the world's 63 billion people—will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels．
"It's not a pretty picture," said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam．Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come．
Already, changes are being felt in Asia but worse is likely to come．Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters．According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate or build sea defenses, storms will become stronger and insects and water-borne diseases will move into new areas as the world warms．
All this comes on top of rising populations and demand for food, water and other resources．Experts say environmental worsening such as deforestation and pollution will likely enlarge the results of climate change．
In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two - thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill．
The year before, a winter cold strike and a summer heat wave killed more than 2,000 people in India．This passage is mainly about ____ ．

Which of the following is NOT true according to the passage?
| A．Asian climate will change greatly． |
| B．Some islands may be flooded in the future． |

Norm Pethrick, a 36-year-old man in Australia’s northern city Darwin, was praised on Thursday for jumping onto a crocodile’s back to save his wife Wendy at Litchfield National Park, a popular tourist spot southwest of Darwin, a local newspaper reported.
Ms. Pethrick was standing on a river bank Wednesday afternoon when the saltwater crocodile lunged (扑), locking its jaws on both her legs as it tried to drag her underwater.
Norm Pethrick, who with his wife had been collecting water, immediately went to help her. He jumped onto the back, poked (戳) the eyes of the crocodile and finally got his wife free.
Ms. Pethrick was later taken to Royal Darwin Hospital for a medical treatment. The doctors said she was suffering eight puncture wounds in her right leg, a puncture wound in her left leg and a serious cut to one of her fingers.
“This could have been a fatal and tragic situation,” said the general manager of Royal Darwin Hospital (RDH), Dr. Len Notaras, according to a local report.
He said Ms. Pethrick was saved by her husband’s “quick and diligent actions”. Dr. Notaras also said she would remain in hospital for three to four days and have an operation to clean the wounds, which are easy to get infected because of bacteria on the teeth of the crocodile.This passage is most likely to be found in ______.
