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 and the University of California, San Diego, has found that you and your friends have more genes in common than strangers do, the Guardian reported.
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 percent of genes that match.
“One percent may not sound like much to the layperson (外行), but to geneticists (遗传学家) it is a significant 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 is it a coincidence that you become friends with people who share your genes? Not at all. In fact, it is evolution 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 critical 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 survive.
Researchers also found that among all the genes studied, those affecting 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 more often and are therefore more likely to meet and become friends with each other.
Based on their findings, the team has developed an interesting test called the “friendship score”. It calculates 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 who your friends are going to be, or would you still prefer to figure it out by yourself and let time be the judge?
1.What is the author’s main purpose in writing the article?
A.To explain why friends share skills and interests.
B.To report on recent findings about making friends.
C.To analyze what influences the way people make friends.
D.To explain an interesting test called the “friendship score”.
2.According to the researchers of the study, people _______.
A.form friendships by complete coincidence
B.are genetically similar to their friends, compared to strangers
C.make friends with those who share nearly 10 percent of their genes
D.may share more similar genes with their friends than with their fourth cousins
3.With the examples of ancient people developing the ability to speak and helping each other build a fire, the author intends to _______.
A.show how ancient people helped each other survive
B.explain that similar interests are what lead to friendship
C.show that it is evolution that brings friends together
D.tell us why it was easier for ancient people to find friends
4.According to the article, people with similar genes that affect their sense of smell ______.
A.like to hang out at cafes more often
B.are easily attracted to the smell of their friends
C.are more likely to be attracted to a similar environment
D.can identify people in a crowd who can become friends

Do you think it is ever a good idea for a teenager to have a credit card?
My kids watch closely as I swipe the card through the register．They’ve seen me do it hundreds, thousands of times．Cool．They are itching to swipe it through the machine themselves． When we walk out of the store with our groceries or pet food, or whatever, it’s almost as though money has not changed hands, painless, easy．
So it shouldn’t be shocking to discover that teenagers are becoming card carrying consumers in their own right．The question is, should they?
While some argue it’s best to teach kids how to use a credit card while still living under the family roof, not everyone agrees． Dave Ramsey, financial expert says getting a credit card for your teenager is actually, “an excellent way to teach him or her to be financially irresponsible．”
Now parents are required to co-sign on credit cards for children under 21．“If their name is on the credit card, then the parent may say, ‘Hey, my name is on this．Don’t get me into trouble,” says Mary Beth Pinto, a marketing professor．“When parents were the co-obligors（共同借贷人），the children caused less debt．If the parents are the co-obligors, the tendency is that the parents were explaining how to use the cards．” Still, Pinto believes parents should start the process much earlier．“Yes, there has to be teaching going on and it has to start when they’re younger． You’re not going to get rid of credit cards．They are here to stay． You have to have them． You can’t fight progress,” Pinto said．
Ramsey, however, disagrees．“Throwing teens into a pool of （credit）sharks is a sure way to guarantee a life-time of heartache,” he said．“You can make online purchases and rent a car with a credit card．Of course, you must have money in your bank account before you can make a purchase with a credit card．But paying for things with money is what you are supposed to do．”
1.The author mentioned her experience in Para 2 mainly to______．
A． prove the convenience of using credit cards
B． tell what impression credit cards leave on kids
C． give advice on using credit cards wisely
D． explain the pleasure credit cards bring to customers
2.The underlined word in Para 2 can be replaced by __________．
A． eager B． afraid C． embarrassed D． thankful
3.What’s Ramsey’s attitude towards teens’ using credit cards?
A． He feels it is worth a try
B． He is very supportive
C． He is strongly against it
D． He considers it as a pleasant experience
4.Pinto will most likely agree that __________．
A． parents should let teens own their credit cards earlier
B． you shouldn’t be in control of credit cards
C． it is never good for anyone to get a credit card
D． learning to use credit cards is practical

Do you blank out or feel so nervous in exams that you have trouble writing answers to questions that you knew just last night? If so, you likely have a case of test anxiety.
But, don't be afraid. By recognizing the problem, you are taking the first step towards overcoming it.
Believe it or not, a touch of nervousness can sharpen your mind, allowing you to perform more quickly. This is because under stress, the body releases the hormone adrenaline (肾上腺素), which prepares it for something important that will happen. However, too much anxiety can result in sleeplessness, loss of appetite before tests, and poor performance. Some people might feel hot and tired. With great anger they often shout or complain for no reason.
If you worry a lot or are a perfectionist, you are more likely to have trouble with test anxiety. Those who have prepared poorly for a test or have had negative experiences taking tests may also experience test anxiety.
When you feel a storm of anxiety coming on, stop what you're doing and make your mind a blank. If possible, actually tell yourself to 'STOP!' This will get your mind off the stress. Then think of being at a place of comfort and let your body relax. As you continue the test, find questions you know the answers to and answer them first. This will help restore your confidence.
Important of all, talk to yourself using positive languages. Make it a habit to replace each negative thought with a logical reason. For example: "I've studied hard and I know the material, so I'm ready to do the best I can."
Another thing you can do is to learn to accept mistakes. In fact, they can be valuable learning opportunities.
Last but not least, start test preparation early — three to five days ahead of the quiz or test. After all, good study habits and skills — for example, time management and note-taking —will give you the feeling that you are in control.
1.What is probably the best title of the passage? ( No more than 10 words )
2. Who will more easily suffer from test anxiety according to the passage? ( No more than 10 words)
_______________________________________________________________________________
3. What does the underlined word “hot” in Paragraph3 probably mean? （No more than 3 words）
_______________________________________________________________________________
4.What makes you feel that you are in control of the test in the last paragraph?
（No more than 7 words）
_______________________________________________________________________________
5.Do you think that a touch of anxiety can have a positive effect? And why?
（No more than 20 words）
