As a teenager, school was difficult for me. I had a kind of attention disorder, which means I couldn’t direct my attention to what I was doing. So when everyone else in the class was centering their attention on tasks, I could not.
In my first reading class, Mrs. Smith asked us to read a story and then write on it, all finished in 45 minutes. I immediately put up my hand and said, “Mrs. Smith, you see, the doctor said I have attention problems. I might not be able to finish the task.”
She looked down at me through her glasses, saying, “You are not different from your classmates, young man.” With her encouragement, I tried. But I didn’t finish the reading when the bell rang. I had to take it home.
In the quietness of my bedroom, the story suddenly all became clear to me. It was about a blind person, Louis Braille. He lived in a time when the blind couldn’t get much education. But Louis didn’t give up. Instead, he invented a reading system of raised dots(点), which opened up a whole new world of knowledge to the blind.
Wasn’t I the “blind” in my class, being made to learn like the “sighted” students? With thoughts running through my head, I found myself deeply attracted in reading and writing. I completed the task in less than 40 minutes. I realized that I was not different from others. I just needed a quieter place. If Louis could find his way out of his problem, why should I ever give up?
I didn’t expect anything when I handed in my paper to Mrs. Smith, so it was quite a surprise when it came back to me the next day with an “A” on it. At the bottom of the paper were these words, “See what you can do when you keep trying?”
1.School was difficult for the writer because ________.
A.he didn’t like the teacher B.the tasks were too boring to him
C.he got a kind of attention disorder D.his classmates talked with him in class
2.Mrs. Smith’s words in Paragraph 3 show that ________.
A.she encouraged him B.she laughed at him C.she felt sorry for him D.she was pleased with him
3.What can we learn from the passage?
A.Never stop reading. B.Never give up easily. C.How to be a great teacher. D.How to learn as a blind.

Success seems to be what everyone longs for in life no matter how old he is. Students want to succeed at study. Adults look forward to their success at work. Have you ever wondered what is the key to success? Some may say the answer is good luck. Some may say hard work is the key. In fact, hard work really does pay off. Scientists find that perseverance(坚持不解) leads to better grades and higher achievements in school.
“Being passionate(热情的) is not enough to make sure that you can achieve success in your schoolwork,” say researchers, and they thought of “courage” as a key to success. Courage is also considered as effort in reaching long-term goals, and a strong will to continue one’s efforts no matter what difficulties they might go through.
Researchers think that the finding could help create new training to help children develop the skill and help them to succeed in their future.
Researchers from the Academy of Finland studied more than 2,000 students from Helsinki. They were followed through their learning from 12 to 16, the sixth grade until the ninth grade in local school years. Researchers found that the factor(因素) that best predicts courage was related to goals. What they had achieved in their past learning played no role in developing the skill.
Professor Katariina Salmela-Aro, who led the study, said, “Courage means a young person is really interested in his or her studies and does not give up easily. A key factor of courage is high perseverance when facing difficulties or in a terrible situation. The important finding is that these factors are the key to success and well-being. Our study shows the power of courage.”
Professor Salmela-Aro also thinks it is important to develop new practices and build character to improve courage in teenagers. She added, “Young people should see everyday school work as part of their life in a wider context(背景) and set achievable goals for themselves. Schools must also serve as a place where it is safe to fail and learn to deal with setbacks. One must not be discouraged by setbacks, but draw power and new energy from them!”
1.What is Paragraph 2 mainly about?
A.Where courage comes from. B.How students can draw power.
C.What courage is thought of as. D.Why having energy is important.
2.According to the passage, Professor Katarina Salmela-Aro believes that ________.
A.courage might be developed with the help of schools
B.teenagers with courage show strong interests in success
C.courage can help reduce the number of difficulties in learning
D.teenagers’ achievement in the past can influence their courage
3.The word “setbacks” in Paragraph 6 probably means “________”.
A.changes B.difficulties C.weakness D.efforts

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?
