Do you have good friends? Do you sometimes feel so close to them that they are like family to you?

It turns out that this isn’t just an expression. A study by Yale University has found that you and your friends have more genes(基因) in common than strangers do. Researchers looked at the genes of 1, 932 people and compared them in pairs of unrelated friends and strangers. They found that friends have 1% of genes that match.

“1% of genes may not sound like much to the layperson(外行), but to geneticists(遗传学家) it is a larger number,” Professor Nicholas Christakis of Yale University told Discovery News. In fact, this is the same amount of genes you share with your fourth cousins, those who have the same great-great-great grandparents as you.

So do you happen to become friends with people who share your genes? Not at all. In fact, it is evolution(进化) that brings you together.

People who share certain genes also share skills and have similar likes and dislikes, researchers said. In ancient times, it was important that people who were alike stayed together. For example, people who had a similar susceptibility(易感性) to the cold were more likely to help each other build a fire, giving them a better chance to stay alive.

Researchers also found that among all the genes studied, those producing a change in sense of smell were the most similar in friends. This is probably because people who smell things in the same way are more easily drawn to similar environments. For example, people who like the smell of coffee may hang out at cafes(咖啡馆) more often and as a result are more likely to meet and become friends with each other.

With their findings, the team has developed an interesting test called the “friendship score”. It can help tell how big the chances are that two people will be friends by studying their genes.

So, here is a question for you: would you like to take this test and know in advance(提前) who your friends are going to be, or would you still prefer to learn about it by yourself and let time be the judge?

1.From the passage, we know that friends ________.

A.look like our cousin B.share 1% of genes with us C.feel close to our family　　　　　　　　　 D.can help us when we feel cold

2.According to the passage, the writer probably agrees ________.

A.we develop our friendship by chance B.our genes decide who we can make friends with

C.everyone should take the test called “friendship score” D.people sharing certain genes have skills and interests in common

3.The writer takes the example of ancient people in Paragraph 5 to ________.

A.study how ancient people dealt with the cold B.predict that similar environments lead to friendship

C.prove that it is evolution that brings friends together D.explain why ancient people gave each other chance to keep alive

4.Which of the following would be the best title for the passage?

A.Friendship: Its Influence on People and Behavior B.Friendship: Its Benefits to Teens and Decision Making

C.Friendship: Is It Necessary to Be Judged by Time? D.Friendship: Is It Possible to Be Influenced by Genes?

九年级英语单选题困难题查看答案及解析

Can you speak to dolphins? Of course you can but you won’t be able to understand them! We interviewed a biologist and asked her what research on dolphin communication has shown. This is what she told us.

Just like dogs, cats and other mammals, dolphins communicate by using sound, vision (视觉), touch and taste. Each dolphin has its own signature whistle to identify itself and to call others. Dolphins don’t have the ability to smell, but their hearing and eyesight are excellent.

We also asked Jane if dolphins have got their own language. She told us that they have and that dolphins started talking to each other from birth. They make different sounds, including whistles, squeaks and click. Sometimes they even sound like a heavy metal band!

We then asked Jane if any interesting experiments have been done. She told us that a very interesting experiment had been done with a mother dolphin and her two-year-old baby in an aquarium. They talked to each other over the telephone! The two dolphins were in separate tanks which were connected by a special under water system. Unfortunately the biologists couldn’t understand what the dolphins were talking about because they haven’t been able to decode (转换) dolphin language yet. However, it was very clear that the dolphins knew what they were talking about.

Finally we asked Jane if there was hope that we would be able to understand dolphins in the near future. She told us that she and her team have been listening to dolphins for more than 17 years, using special equipment to record and analyze their language. Unfortunately they haven’t been able to decode it yet, but who knows — maybe one day we’ll get a phone call from a dolphin.

1. It’s clear that ________.

A. we can speak to dolphins but not talk with

B. dolphins have not got their own language

C. researches on dolphins have just begun

D. only biologists know what dolphins talk about

2. The best title of the reading may most probably be_______.

A. An Interesting Experiment

B. Mother Dolphin and Baby

C. Animal Talk

D. Further Research

3. The word “analyze” in the reading mean________.

A. use　　 B. translate　　 C. copy　　 D. study

4.Which of the five senses haven’t dolphins got?

A. Smell　　 B. Touch　　 C. Taste　　 D. Vision

5. The interesting experiment tells us_______.

A. dolphins could talk in their own language

B. only mother dolphin was able to talk to her baby

C. the biologists can decode dolphin language

D. the two dolphins were talking by touch

九年级英语单选题中等难度题查看答案及解析

Is it possible for animals to raise a human child? There are many stories that suggest it is possible. Not just wolves and dogs, but also sheep, bears and even monkeys are able to look after human children, Daily Mail reported.

There is the case of Ivan Mishukov, a 6-year-old boy from Moscow. Police found him living with dogs in the city's streets in 1998. There, he had been begging for two years. Ivan found food to feed the dogs. And in return, the dogs kept him warm and protected him while he slept. When he was saved, he could hardly speak. Luckily, he later joined the army and lived like a normal adult.

But not all children who are raised by animals can adapt to human society. In 1848, British soldier Colonel William Sleeman found a little boy living with many wolves in India. He took him to a village, taking care of him and trying to teach him to speak. But nothing worked. The boy still behaved like a wolf, eating raw (生的) meat and refusing to wear clothes, no matter how cold the weather was. About two years later, he got very sick and passed away.

Some animals are believed to have strong maternal instincts (母性本能), which guide them to care for young animals, even those of other species(物种). However, people need to know that children raised by animals may experience long-term negative effects when they enter human society, according to Daily Mail.

1.Ivan Mishukov was raised by________.

A.wolves B.monkeys C.dogs D.bears

2.What could the dogs do for Ivan?

A.They begged food for him. B.They warmed him.

C.They talked with him. D.They took him to join the army.

3.The case of the boy raised by wolves shows us that children raised by animals________.

A.can learn from animals B.can live longer

C.can speak animal language D.may harm human beings

4.What did the Daily Mail say?

A.Animals can take good care of human babies.

B.Some animals have strong maternal instincts.

C.Some animals can't tell themselves apart from other species.

D.Children raised by animals are stronger than other people.

5.Where might you find this passage?

Many animals around us are smart. Let’s get to know some of them.

Dolphins are smarter animals in the sea. Researchers put sea animals to a test. In the test, the researchers made red marks on the animal’s bodies and took them in front of a mirror. Many sea animals either ran away or fought with the ones in the mirror. However, when the dolphins saw themselves in the mirror, they tried to clean the red marks off their bodies. So the researchers believed that the dolphins knew the ones in the mirror were just themselves.

Bees work hard, and they are smart enough to learn something. Researchers found a group of bees and taught them to tell which horizontal line (水平线) was higher than the other. If they could find the higher line, they would get sugar as a prize. After training for a period of time, the researchers tested the bees. To their surprise, the bees found the higher horizontal line quickly and got sugar. Instead, when the researchers showed them vertical lines (垂直线), the bees simply flew away, because they knew there was no way to get sugar.

Chimpanzees (黑猩猩) are very human-like. They can learn fast and well. Researchers showed the numbers from one to nine on the screen. Chimpanzees and some college students were asked to remember where the numbers were after watching the numbers in less than a second. The adult chimpanzees and the college students performed almost the same, but the young chimpanzees performed much better. It was amazing.

1.In the test, the dolphins _______________.

A. felt afraid and ran away from the mirror

People are always afraid of making mistakes. But sometimes it’s not bad to make mistakes, and here is way.

At first, mistakes are a clear sign that you are trying new things. It’s always good to try new things, because when you are trying new things you are growing. If you never try new things, how can you improve? How can you create? The simple answer is, “You can’t.” Look around you, everything you see is the result of someone trying new things.

Another good thing about mistake is this: when you are making mistakes, you are learning. Consider this : Edison failed 10,000 times before he invented the light bulb. When he was asked how he felt to fail that many times, he said that he hadn’t failed 10,000 times, but rather had learnt 10,000 things that didn’t work.

Finally, when you make a mistake, you are that much closer to success. Why? Because you have said what you should say, and you have done what you should do. Every time you make a mistake, you are closer to success. But it doesn’t mean that you can make mistakes without thinking. Instead, when you try new things you have to think them over, so that you can keep away from some unnecessary mistakes.

We shouldn’t spend all our time and money on the only one way, but use them correctly. Because our time and money are limited(有限的) .

There is an old saying, “ If you are not making mistakes, you are not trying hard enough.” So go bravely and make mistakes. And learn. And grow. And succeed.

1. If you are making a mistake, that means_______ .

A. you are careful.　 B. you’re kind.　

C. you ‘re growing. D. you know nothing.

2. If you never try new things, you can’t _____ .

A. improve　　　　 B. create　　 C. spend　　 D. A and B

3. After Edison failed 10,000 times, he ________ .

A. gave up　　　　　　　　　　　 B. invented the light bulb.

C. invented the computer.　 D. invented 10,000 new things.

4.When you make a mistake, you are closer to_______ .

A. time　 B. money　　 C. success　　 D. everything

5.What’s the main idea of the passage?

A. Never make mistakes.

B. You can make mistakes without thinking.

C. Sometimes it’s good to make mistakes.

D. Making mistakes is terrible.
