　26.D．解析：通过对整篇文章的理解，D项最符合。
　　C
　　For a long time being happy was considered natural，and there was nothing special to do about it. Now we know that we can work at getting along well with other people. It is possible to act in such a way that other people will like us better.
　　One way is being unselfish，not wanting everything your own way or asking for the best share of everything, including the attention of your friends. Another way is to look for good points, not bad ones in other people.
　　You don’t have to be spineless(无骨气的)in order to be popular. In fact，you will be liked and respected(尊重)if you are not afraid to stand up for your rights(权利). But do it politely and pleasantly. One way to develop a good character is being friendly and polite to your own group,  to older people，to strangers and especially to those who do not look important or do not interest you.
　　You cannot expect to be p erfect,  so you must learn not to b e too unhappy when you make a mistake. Everyone makes mistakes, and no one is to be blamed unless he refuses to learn from them. Many young people become discouraged(泄气的) when they know their unpleasant qualities—selfishness，laziness，etc. Just remember that we all have some of these faults and have to fight against them.
　　When sometMng is wrong，it is best to try to make it right. Perhaps you don’t like a teacher or a classmate. Try to see why，and look at yourself，too. Make sure that you are not doing something to make others dislike you. In time, things may turn out all right, then you simply have to learn to get along the best you can w ith the situation, without thinking too much about it. Worrying never helps in a situation you can’t change.
　　27．Which of the following is the closest in meaning to the underlined part?
　　A.Not sharing anything with others.
　　B.Not thinking too much of yourself.
　　C.Not attracting the attention of your friends.
　　D.Not making friends with people who have bad points.
　　28．How can we get along well with others according to the passage?
　　A.We should find out unpleasant qualities in others and in ourselves.
　　B.We should show others our unpleasant qualities.
　　C.We should stand up for our rights in any way we like.
　　D.We should fight against our unpleasant qualities.
　　29．What can we know from the passage?
　　A.Even if we don’t have good relationships with others，we needn’t work at it.
　　B.Even if someone is not important to us，we still need to treat him politely.
　　C.Even if we are willing to learn from ouy mistakes，we are still to be blamed.
　　D.Even if the situation cannot be changed, we still need to worry much about it.

　　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(物质) that cause illnesses，as well as aging.
　　In another study，researchers ined 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.
　　T he 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.
　　30．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.
　　31．What result did the researchers find out?
　　A.Apples produce chemicals that can change hu man 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.
　　32．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.
　　33．What can we infer(推断)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.
　　△旨大意】天个苹果，疾病远离我，可最近项研究表明，天个苹果，有助于抗老化。

　　31.B 解析：根据“According to the result, the researchers believed that the antioxidants(抗氧化剂) in the apple extract helped clean up dangerous chemicals(物质) that cause illnesses，as well as aging.”
　　32. C。 解析：根据“when dinosaurs began to die off the plant，which would finally become today’s apple tree, experienced a great genetic change.”
　　33.A解析; 吃苹果会给我们带来更多的优点比我们可能相信之前。
