Ask any group of teenagers in the UK what they most like to eat, and foods like pizza, burgers and chips are always mentioned.
But what teenagers like to eat is not necessarily what they should be eating. According to the National Diet and Nutrition (营养) Survey, far too many young people in the UK between the ages of 4 and 18 eat too much fat, sugar and salt in their diet and take in too many calories. And their intake of starchy carbohydrates (含淀粉的碳水化合物), fiber, iron, vitamins and calcium (钙) is too low.
For a growing body, eating foods containing plenty of calcium, such as milk, yoghurt and cheese, is very important as calcium is essential for the development of healthy, strong bones. Similarly, foods that are rich in iron are good for young rapidly developing bodies, so red meat, bread, green vegetables, and dried fruit are also good to eat.
It is during our teenage years that lifestyle habits can become entrenched (根深蒂固的), so it is important that young people are educated about what foods are good for them. In 2005, in order to change eating habits and open teenagers' minds to new tastes, chef Jamie Oliver started a "Feed Me Better" project. As part of a television series, "Jamie' s School Dinners", he worked with teachers and cooks in a number of schools across the UK to provide more nutritious school meals. Although some teenagers and parents refused to have a try at first, the project went very well and helped to influence governmental policy on nutritional standards for school meals.
No one expects to end the teenage love affair with fast and junk food but, hopefully, if projects like "Feed Me Better" continue to give out the right messages, more young people will understand the importance of eating healthily.

Grasshoppers are having to change their song — one of the iconic sounds of summer — to make themselves heard above the noise of road traffic, ecologists have discovered. The study, published in the British Ecological Society's journal Functional Ecology, is the first to show that human-made noise affects natural insect populations. Animals use sound to communicate for many reasons, including marking out territory, warning of predators and finding mates, and although previous research shows birds, whales and even frogs change their calls in noisy environments, the impact of human-made noise on insects has been neglected until now. Ulrike Lampe and colleagues from the University of Bielefeld in Germany caught 188 male bow-winged grasshoppers, half from quiet locations and half from beside busy roads. The grasshoppers use their song to attract mates.
The team then studied the differences in the two groups' songs in the laboratory. To encourage them to sing they exposed the males to a female grasshopper, and then recorded their courtship songs. Analysis of almost 1,000 recordings revealed grasshoppers living beside noisy roads produced different songs to those living in quieter locations.
According to Lampe: "Bow-winged grasshoppers produce songs that include low and high frequency components. We found that grasshoppers from noisy habitats increase the volume of the lower-frequency part of their song, which makes sense since road noise can mask signals in this part of the frequency spectrum(频谱)."
The team's findings are important because traffic noise could be upsetting the grasshopper's mating system(交配系统). "Increased noise levels could affect grasshopper courtship in several ways. It could prevent females from hearing male courtship songs properly, prevent females from recognizing males of their own species, or impair females' ability to estimate how attractive a male is from his song," Lampe explains.
Having discovered that human-made noise affects insect communication, the researchers now want to learn more about how the mechanism works, and whether the grasshoppers adapt to noise during their development as larvae（幼虫）, or whether males from noisy habitats produce different songs due to genetic differences.
The bow-winged grasshopper is a common species in Central Europe. Adults occur mainly between July and September, preferring dry grasslands. Around 1.5 cm long, they vary in colour from green and browns to red and purple. The male's song consists of 2 second-long phrases that increase in amplitude (振幅) towards the end. The beginning of a phrase is characterized by slower ticking sounds that increase in speed and amplitude, leading to a buzzing sound towards the end of the phrase. A courtship song usually includes 2 phrases.The author wrote the article to _________________.

WASHINGTON The head of the World Bank says for the first time in human history, it is possible to end poverty around the world. Jim Yong Kim told a Washington audience Tuesday, he wants to make ending world poverty by 2030 a top goal for the bank and governments around the world.
World Bank President Jim Yong Kim says that the problems of poverty, hunger and inequality are wide, urgent and a matter of survival of millions.
“We know that despite the great successes of the last decade, there are still about 1.3 billion people living in extreme poverty, 870 million who go hungry every day, and 6.9 million children under five dying every year,” he said.
But Kim told a Washington audience that the previous successful efforts to cut the number of people living in extreme poverty by half give them hope.
“We are at an auspicious moment in history, when the successes of past decades and an increasingly favourable economic outlook combine to give developing countries a chance－for the first time ever－to end extreme poverty within a generation,” he said in a speech at Georgetown University. “Our duty now must be to ensure that these favourable circumstances are matched with deliberate decisions to realize this historic opportunity.”
Kim says success will require increasing the speed of economic growth, particularly in South Africa and South Asia.
But he warned that civil unrest could happen if economic growth does not help people at all income levels, and also include women and youth．
Kim says that the World Bank and other development agencies will have more resources to get this job done right. “Meeting this 2030 goal will take extraordinary effort,” he said.
However, Kim warned that all the progress in fighting poverty could be destroyed by climate disasters unless the nations of the world do more to prevent climate change.In the opinion of Jim Yong Kim, world poverty _____．
| A．is difficult but hopeful to end by 2030 |
| B．exists only in Africa and Asia |
| C．is not quite hard to end by 2030 |

Which of the following gives Jim Yong Kim the hope to end world poverty?
| A．Economic growth is increasing in developing countries． |
| B．Great successes have been achieved in science and technology． |
| C．A decreasing number of people are living in poverty． |
| D．All countries have started to fight poverty． |
The underlined word "auspicious" in Paragraph 5 most probably means "_____"．
| A．unforgettable | B．lucky |
| C．disappearing | D．important |
What’s the passage mainly about?
| A．The key of ending world poverty is preventing climate change. |

| D．The progress in fighting poverty. |
You are watching a film in which two men are having a fight. They hit one another hard. At the start they only fight with their fists. But soon they begin hitting one another over the heads with chairs. And so it goes on until one of the men crashes (撞击) through a wind and falls thirty feet to the ground below. He is dead！Of course he isn't really dead. With any luck he isn't even hurt. Why? Because the men who fall out of high windows or jump from fast moving trains, who crash cars or even catch fire, are professionals. They do this for a living. These men are called stuntmen. That is to say, they perform tricks. There are two sides to their work. They actually do most of the things you see on the screen. For example, they fall from a high building. However, they do not fall on to hard ground but on to empty cardboard boxes covered with a mattress (床垫). Again, when they hit one another with chairs, the chairs are made of soft wood and when they crash through windows, the glass is made of sugar! But although their work depends on trick of this sort, it also requires a high degree of skill and training. Often a stuntman' s success depends on careful timing. For example, when he is "blown up" in a battle scene, he has to jump out of the way of the explosion just at the right moment.
Naturally stuntmen are well paid for their work, but they lead dangerous lives. They often get seriously injured, and sometimes killed. A Norwegian stuntman, for example, skied over the edge of a cliff (悬崖) a thousand feet high. His parachute (降落伞) failed to open, and he was killed. In spite of all the risks, this is no longer a profession for men only. Men no longer dress up as women when actresses have to perform some dangerous action. For nowadays there are stuntgirls too.Stuntmen are those who ______.
| A．often dress up as actors |
| B．prefer to lead dangerous lives |
| C．often perform seemingly dangerous actions |
| D．often fight each other for their lives |
Stuntmen earn their living by ______.
| A．playing their dirty tricks |
| B．selling their special skills |
| C．jumping out of high windows |
| D．jumping from fast moving trains |
Which of the following is the main factor (因素) of a successful performance?
| A．Strength. | B．Exactness. |
| C．Speed. | D．Carefulness. |
What can be inferred from the author' s example of the Norwegian stuntman?
A.Sometimes an accident can occur to a stuntman.
B The percentage of serious accidents is high.
C. Parachutes must be of good quality.
D. The cliff is too high.
Several interesting American museums tell about health subjects. One is the Doctor Samuel D. Harris National Museum of Dentistry. It is at the University of Maryland in Baltimore. That is where the first college in the world to train dentists began. The museum tells about the history of the medical treatment of teeth.
Visitors can see some frightening devices that once were used to remove infected (受感染的) teeth. They also can see sets of teeth made of animal bone. They were made for a famous American -- the first President, George Washington. Most people do not consider a visit to the dentist their idea of a good time. However, the director of the museum says he wanted to make the museum a fun place to visit. He says he also wants to teach visitors about the importance of taking care of their teeth.
Another museum collects devices that help people hear. The Kenneth W. Berger Hearing Aid Museum is at Kent State University in Kent, Ohio. The museum has more than three-thousand hearing aids from around the world. They include old and strange devices. Some hearing aids were made to look like other objects. That is because in the past many people did not want anyone to know they were wearing a hearing aid. It is common for people to think it uneasy to pay a visit to ____.
| A．the University of Maryland | B．the Museum of Dentistry |
| C．the Hearing Aid Museum | D．the dentist |
The text mainly tells about _____.
| A．museums in the US |
