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.

Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion . There are a lot of people to feed. We need more  and more food.
One way to produce more food is growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic（遺傳的） material. Foods from plants grown in this way are called genetically modified(改變的) foods, or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases; a kind of rice is being prepared , for example , which stops people becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are,. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people , then hurt them or their children later. But both rich and poor countries are interested in their use, and they are not going to go away. In 2050, we may think differently about them.

Liu Xu is a student from a middle school in Guangxi. Once he was riding home when a  robber (盜賊) suddenly jumped out from the roadside. He pulled Liu Xu off his bike and rode away. Liu Xu was scared, but he didn’t run after the robber. He found a telephone and called the police at 110.
“Safety is the first important in such a situation,” Liu said, remembering what his teacher had told him in his first aid class. “It is not safe to run after an adult who is stronger than you.”
Liu’s school has compulsory (必修的) first aid education. Students must take the class once a week.
Teenage safety has become a serious issue recently. According to a survey, about 16,000 teenagers die in accidents in China every year.
At Liu’s school the first aid classes are to “teach students skills how to protect and save  themselves in emergencies (緊急情況)”. Students there often learn by role-playing in first aid classes. For example, one student performed as a stranger knocking at a door. Another one stood inside the door and asked several questions before letting the “stranger” in. Then they changed roles and did it again. They learned a lot while having fun at role-playing.
The topics of the first aid classes are regularly updated (適時(shí)的). The students have learned skills for surviving in earthquakes. The teacher also taught the students not to go out at night. If someone tried to do bad things to them, they should quickly run into crowed place.

In the United States, children start school when they are five years old. In some states they must stay in school until they are sixteen. Most students are seventeen or eighteen years old when they leave secondary（中等的） schools. There are two kinds of schools in the United States: public schools and private（私立的）schools . Most children go to public schools. Their parents do not have to pay for their education because the schools receive money from the government. If a child goes to a private school, his parents have to get enough money for his schooling. Some parents still prefer private schools, though they are much more expensive. Today about half of the high school students go to universities after they finish the secondary school. A student at state university does not have to pay very much if his parents live in that state. But many students work while they are studying at universities. In this way they develop good working habits and live by their own hands.
小題1: Children can go to school at the age of four in the U.S.
小題2:Most parents prefer to send their children to private schools in America.
小題3:About fifty percent of high school students can go on to universities after they leave the secondary school today.
小題4:Lots of American students go to universities by depending on their parents completely (完全地).
小題5:The passage is mainly about American education.

After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液態(tài)）water. Scientists think there is a chance that the planet could have life.
The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（萬(wàn)億）kilometres －500 million times farther away from us than the moon.
A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft don’t come anywhere near that one-tenth light-speed mark.
At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the sight distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.
Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望遠(yuǎn)鏡）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化學(xué)物質(zhì)）around the planet and discover it Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has life or not. But it’ll probably be many years before we can do this properly.
People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers.
小題1: What did scientists find in September 2010?
A．A planet with water. B．A planet similar to the earth.
C．A planet without life.D．A planet near the earth.
小題2:According to the article, Gliese 581g ________.
A．is at the right distance from its starB．moves around the earth
C．is as far away from us as the moonD．can be reached in about 220 years
小題3: Paragraph 5 is mainly about ______.
A．the possibility of living on Gliese 581g
B．the kinds of chemicals around Gliese 581g
C．the way of looking for life on Gliese 581g
D．the aim of studying the radiation on Gliese 581g
小題4:Which of the following is the best title for the passage above?
A．Gliese 581g, a Likely Living PlanetB．Gliese 581, a Likely Living Planet
C．Gliese 581g and Its StarD．Gliese 581g and Radiation

MSG(monosodium glutamate) is a food additive(食品添加劑),which has been widely used by many food factories all over the world since it appeared first in Japan in 1909.
MSG is a substance that is added to some food to improve its original(原先的) taste and colour. It is used in foods around the world such as cakes, bread, frozen meats, fish and vegetables. In the beginning, people thought MSG was safe just like salt and sugar. However, in 1968 some people reported they seemed to have bad reactions(反應(yīng)) to MSG after having had a meal at a restaurant. They included headaches and quick heartbeat(心跳).It was also reported that MSG excited a person’s brain and caused his death in Japan. Scientists think that MSG may lead to many neurological disorders(神經(jīng)紊亂).In mice studies done by a university, the evidence showed the mice didn’t want to eat the food including MSG.
Today many food companies “hide” MSG on food labels(標(biāo)簽) by using different names. If you see “natural flavorings”,“hydrolyzed protein”and “spices” in a food label, you are probably seeing a hidden way to “report” MSG in a food label. Every time we have a meal in a restaurant, we always feel the food very delicious to taste, but sometimes it is dangerous for our health because some poisonous food additives have been added to the food.
To protect people’s health, our governments, from central to local, are taking actions to stop factories producing poisonous food additives.
小題1: Monosodium Glutamate is _______
A．a(chǎn) foodB．a(chǎn)n additiveC．a(chǎn) factoryD．a(chǎn) country
小題2:MSG is often used in ______.
A．frozen meatsB．cupsC．clothesD．book covers
小題3:The examples in the second paragraph tell us ________.
A．the food including MSG is deliciousB．people like to eat in a restaurant
C．mice like eating the food including MSGD．MSG is not safe sometimes
小題4:If you see “natural flavorings”,“hydrolyzed protein” and “spices” in a food label, you will know ­­­­­­­_____________.
A．you must eat the food in a hidden way
B．the food label must be hidden
C．MSG is probably added to the food
D．you must report the food to your parents

What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects believe that they are all possibilities. The only thing for sure is that the houses will be as green as possible.
The tree house
Many architects in the world would like to build a “tree house.” Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to the home’s temperature.
The Lizard house
Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.
Meals at home
This design is perhaps as much about the future of food production as architecture (建筑風(fēng)格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.
Learning from the past
Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技術(shù)) can also help cut down energy use. For example, a chimney (煙囪) can be a useful air conditioner because it is easier of hot air to flow out at the chimney.
小題1:What is the best title (標(biāo)題) of the passage?
A. Green house of the future.
b. The greener, the better.
C. How to build green houses.
D. Changes of the houses.
小題2:We can heat water, produce electricity or create fresh air for the home            .
A. with the root of a leaf.
b. with the energy from sunlight.
C. with the soil under the ground
D. with gardens on its walls.
小題3:What will happen to the cover of the lizard house when it’s in the bright sun?
A. It will take in light.
b. It will produce energy.
C. It will turn dark.
D. It will turn white.
小題4:The passage seems to tell us that meals at home in the future            .
A. will be more delicious.
b. need more cooks.
C. cost as much as possible.
D. will be greener.
小題5:A chimney can be a useful air conditioner but it used to cause          .
A. pollution.   b. accident.     C. noise.      D. techniques.
