Smog is a big problem in many Chinese cities. But it seems that besides wearing a mask, few of us know what has caused the smog and what to do to beat it. Chai Jing, a former news interviewer with CCTV, discussed the questions in her documentary Under the Dome.

The 103-minute film was on websites on Feb 28. In the film, Chai visits polluted places and talks to officials and scientists. She thinks that burning too much coal and oil are the main causes of PM2.5 and smog.

To solve the problem, Chai suggests that we should clean our coal and oil or replace them with cleaner energy such as natural gas. In her film, Chai also emphasized (强调) that everyone can do something to help control smog too. For example, we can live a greener life by using more public transport. Or if we see things that could harm the environment, we can try to stop it. In the film, when she sees a restaurant cooking without any suitable filter facilities (过滤设备), she calls the hotline 12369. The restaurant installed the filter a week later.

Chen Jining, the new minister of environmental protection, praised Chai. “This film encourages ordinary people to take notice of the environment. This is what we need in the future.”

3.What can we tell from the story?

A. Only factories produce heavy smog.

B. Only the government can control smog.

C. Smog can’t be controlled by ordinary people.

D. Living a green life can help reduce smog.

4.What’s Chen Jining’s attitude towards Chai’s film?

You are probably familiar with the saying:An apple a day keeps the doctor away. A recent research carried out by the Chinese University of Hong Kong may change the saying:An apple a day may keep aging away.

The research chose fruit flies(果蝇), as they share many genes(基因)with humans. The fruit flies were either fed normally or had an apple extract(浓缩物) added to their diet.

It turned out that those fruit flies that were given apple extract lived about 55 days—five days longer than the flies that were normally fed. The research group also found it easier for the flies to walk, climb and move about as they aged.

According to the result, the researchers believed that the antioxidants(抗氧化剂) in the apple extract helped clean up dangerous chemicals(化学物质) that cause illnesses, as well as aging.

In another study, researchers examined diets of thousands of women. They discovered that those who regularly ate apples were 20 percent less likely to suffer heart illnesses and stroke.

The apples’ genetic code(遗传密码) was discovered recently. It allows scientists to develop nicer and healthier fruits. Researchers are already using the information to grow a kind of apples full of antioxidants that can keep eyes and joints healthy and protect humans against heart illnesses and cancer.

Apples that kill the desire(欲望) to eat could also be produced, with the first“extra-healthy’’apples on supermarket shelves within just four or five years.

The team that keeps studying apple DNA includes 100 scientists from five countries. Their research also suggests that around 65 million years ago, when dinosaurs began to die off the plant, which would finally become today’s apple tree, experienced a great genetic change. The number of many of its genes doubled. The extra genes allowed the apple to get used to worse conditions and go through a different development from peaches, strawberries and other related fruits.

1.Why were fruit flies used for the research?

A. Because they have a similar diet to humans.

B. Because they have a history as long as apples.

C. Because they feed on nothing but apple extract.

D. Because they share a lot of genes with humans.

2.What result did the researchers find out?

A. Apples produce chemicals that can change human genes.

B. Apples have antioxidants that kill chemicals that cause aging.

C. Apples are rich in vitamins that are needed in humans’ bodies.

D. Apples produce chemicals that make apples taste more delicious.

3.What happened to apples around 65 million years ago according to the research?

A. Their genes stopped their development as the environment got worse.

B. Their genes became twice in number but they finally died off like dinosaurs. [

C. They experienced a great genetic change making them used to worse conditions.

D. They went through a similar development to peaches, strawberries and other related fruits.

4.What can we infer from the passage?

A. Eating apples may bring us more advantages than we might believe before.

B. People who have the habit of eating apples don’t need to see a doctor.

C. Apples that kill the desire to eat are already available in supermarkets now.

D. People will eat apples instead of peaches and strawberries from now on.

We all dream about things that we would like to do and things we hope to achieve in the future. But are everybody’s dreams the same? Here are some of the findings of a survey about hopes and dreams, in which thousands of students across China took part.

What are the hopes of teenagers? We received several different answers to the question: what would you like to do after you finish your education? It seems that some students would like to start work as soon as they can, so that they can help offer their parents better lives. Other students hope to go on studying after they finish school and to go to university. Although money is important, many teenagers want to do jobs they like. According to the survey, the most popular choice of job is computer programming.

What are the dreams of teenagers? Teenagers have all kinds of dreams. Some are more realistic(现实的) than others. For example, many students would like to be volunteers if Beijing could hold the World Cup, maybe working as translators or tour guides. And many students dream of having a trip to every corner of the world one day.

According to the survey, less realistic dreams are also common, but many students reported that they were willing to work hard to achieve their dreams. Quite a few dreamed of becoming famous, perhaps famous sports people or singers. Some students would like to go on exciting trips. One student would love to sail across the Pacific Ocean. And then there are dreams that there is no possibility for students to achieve. Three students would like to be able to fly.

It is clear from the survey that teenagers have similar hopes. It seems that most students hope to have a good education and find a good job. On the other hand, students dream of very different things: good things, and even crazy things. It is very important to dream, so hold on your dreams, one day they may just be realized.
