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.
【小題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.
【小題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.
【小題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.
【小題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.

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon. They don’t feel hurt. If the same two people meet again, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand. Friendships between us develop more slowly but may become lifelong feelings, extending(延伸)deeply into both families.
There is another difficult point for us to understand .Although Americans treat friends warmly in their personal everyday lives, they don’t show their politeness to them if it requires a great deal of time. But in China, we are usually generous with our time. We, as hosts, will appear at an airport even in the middle of the night to meet a friend. We may take days off from our work to act as guides to our friends: It is opposite in America, Americans can not manage the time to do a great deal with a visitor outside their daily plans. They will probably expect the visitors to get themselves from the airport to the hotels. And they expect the visitors will phone them from there. Once the visitors arrive at their homes ,the welcome will be full, warm and real.
For Americans, it is often considered more friendly to invite a friend to their homes than to restaurants, except for business matters.

Good evening, ladies and gentlemen. Welcome to the nine o’clock Mystery Hour. Today we’ll show you two British stories. We hope you’ll enjoy them.
About 900 years ago two green children arrived in a small village in south England. Their eyes and skin were green and they spoke a strange language. They were very tired and weak, so the people of the village looked after them. The boy died a year later, but the girl grew strong and lived the rest of her life there. And her skin colour turned back to normal day by day. Scientists say that sometimes of people don’t have enough food to eat for a long time, their skin goes very pale and can even turn green.
Loch Ness is the largest lake in Scotland. It’s a very deep and cold lake. For hundreds of years, people have talked about a monster(怪物) called Nessie which lives in the lake. About seventy years ago, two people saw something moving in the lake. They said that the animal was playing and rolling around in the water. Since then many people say they have seen the monster. Their descriptions are always the same. It looks like a dinosaur, with a very long neck and a small head. It has a big bump(包,腫塊)on its back. People have tried to photograph the animal, but the pictures have not been very clear. Scientists don’t know whether there is a monster or not. Some say it may be a whale or a very large fish. Some think it’s a snake. Others say there’s nothing at all— nothing but people’s imagination. Maybe we’ll never know what’s in Loch Ness.
【小題1】What kind of story is talked about in this programme?

A.Romantic stories.B.Mysteries.C.Horror stories.D.Comedies.
【小題2】Which sentence is TRUE about the two green children?
A.They both enjoyed a long and happy life.
B.The girl’s eyes and skin were green all her life.
C.At first they spoke the same language as people in the small village did.
D.Maybe they hadn’t eaten enough for long before they reached the village.
【小題3】What does Nessie look like according to some witnesses? 

【小題4】What can we learn from the second story?
A.Scientists are still not sure whether there is a monster or not in Loch Ness.
B.Loch Ness is very deep and warm lake in Scotland.
C.People have taken very clear pictures of Nessie.

閱讀下面短文,將短文中畫(huà)線部分的句子翻譯成中文
How Much Water Is Needed a Day?
Many people think they should drink eight glasses of water a day.Why? Because that is what they have been told all their life.But a new report on science gives some different suggestions:people should drink according to their bodies.112.They should drink as much water as they would like to drink.
The report says most people meet their daily needs for water by letting thirst be their guide.It also gives people some good suggestions:women should get about 2.7 liters(升)of water every day,while men should get about 3.7 liters.
There is an important difference.113.The report doesn’t tell people how many glasses of water to drink.Instead,the experts say it may not be possible to know how many glasses people really need.This is because the daily want of water can include the water in foods.

閱讀下面短文,根據(jù)短文內(nèi)容完成下列各題。
What will the home of the future look like? A team of architects (建造師) in Hong Kong say that city homes will be tiny, as populations continue to grow and space becomes more expensive. They have designed “space flats”. 83它們只有30 平米大。These flats have three small rooms, a living room, a bathroom and a bedroom, as well as a balcony (陽(yáng)臺(tái)),but everything is carefully planned to make good use of the limited space.
The living room is the main room of the flat. It can be used as an office, a kitchen or even a second bedroom. There is a sofa that can be changed into a bed. The dining table can be changed into a computer desk. And, if not needed, both the sofa-bed and the table can be folded away and stored into a small apace in the wall. There is a flat-screen TV, which can also serve as a computer monitor. In one corner of the room, a small cooker, a microwave oven and a miniature refrigerator are hidden out of sight.
The other rooms are small but useful. The bathroom contains a toilet and a shower. The double bed in the bedroom can also be a sofa, if necessary, The balcony has enough room for two people to sit and enjoy the view from the block of flats. All the rooms have high ceiling to provide as much storage space as possible, while the flat has large windows to let in plenty of sunlight.
“Space flats “are now being tested in a building in Hong Kong. “It’s wonderful,” said one resident(居民) “84. The flat is so well designed that you feel that there is plenty of space”
【小題1】Why do the architects think that “Space flats “will be important in the future?
