One in four Chinese primary school students say they are too busy to eat fruit every day, while many dislike fruit for the simple reason that their __16__tell them to eat it.
That is the result of a recent survey __17__the Chinese Association for Student Nutrition & Health Promotion(中國學(xué)生營養(yǎng)和健康促進(jìn)協(xié)會(huì)), who last month issued a questionnaire among 1,500 children in Beijing, Shanghai and Guangzhou. They__18___ 28 percent didn't eat fruit every day and of those who did, one in seven did not eat enough.
Among students who didn't eat fruit every day, 50 percent said it was because they "didn't have time" and 40 percent of those who didn't like fruit said it was because "my parents____19___ me to".
"Fruit is a natural source of many nutritional elements(營養(yǎng)元素), can balance a person's nutritional intake and help to ___20___overweight(超重)," says Association director Du Yuxia.
He says about 20 percent of primary school students in Beijing and Guangzhou are overweight, while the figure is  __21___30 percent in Shanghai.
Hu Xiaoqi, a nutrition expert with the Chinese Center for Disease Control and Prevention (CDC), believes a student should eat at least 150 grams of fruit a day. Moreover, fruit juice is not an adequate substitute because the fruit __22__ contains more fiber and vitamins than juices, which are usually high in sugar and contain preservatives.
Hu says primary school students should be encouraged to eat one or two fruits every day. ___23___many students found they didn't have time to eat fruit before breakfast or in the evening, they should be encouraged to ___24__fruit to school and eat it during class breaks . Finally, she suggests that parents encourage their children to eat fruit, instead of forcing them.
Ma Guansheng, deputy ___25____of the CDC's Nutrition and Food Safety Institution(營養(yǎng)和食品安全機(jī)構(gòu)), says: "6-12 years old is a crucial time for physical development. Children at this age need an adequate and balanced nutritional supply to guarantee the normal growth of the body."

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(果蠅), as they share many genes(基因)with humans. The fruit flies were either fed normally or had an apple extract(濃縮物) 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(抗氧化劑) in the apple extract helped clean up dangerous chemicals(化學(xué)物質(zhì)) 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(遺傳密碼) 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 share a lot of genes with humans.

D.Because they feed on nothing but apple extract.

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(推斷)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.
