Bob was happy. He was at a new school, and the other students were friendly. “Hi, Bob!” they said. But some students said, “Hi, Peter!” Bob didn't understand. He asked another student, “Why do some students call me Peter?”

“Oh, that's easy to answer,” the students said. “Peter was a student here last year. Now he goes to a different school. You look like Peter. Some students think that you're Peter.”

Bob wanted to meet Peter. He got Peter's address from a student and went to Peter's house. Peter opened the door. Bob couldn't believe(相信) his eyes. He looked really like Peter! Bob and Peter had the same color eyes and the same smile. They had the same black hair. They also had the same birthday. And they both were adopted(领养) by two different families.

Bob and Peter found out that they were twin brothers. Soon after the boys were born, one family adopted Bob, and another family adopted Peter. Bob's family never knew about Peter, and Peter's family never knew about Bob.

Bob and Peter's story was in the newspaper. There was a photo of Bob and Peter next to the story. A young man named John saw the photo in the newspaper. John couldn’t believe his eyes. He looked really like Bob and Peter! He had the same color eyes and the same smile. He had the same black hair. He had the same birthday. And he, too, was adopted by another family.

Later John met Bob and Peter. When Bob and Peter saw John, they couldn't believe their eyes. John looked really like them! Why did John look really like Bob and Peter? You can guess. Bob and Peter are not twins. Bob, Peter and John are triplets(三胞胎).

一、阅读理解(共1道小题,共50.0分) 1. Americans with small families own a small car or a large one. If both parents are working, they usually have two cars. When the family is large, one of the cars is sold and they will buy a van(住房汽车) A small car can hold four persons and a large car can hold six persons but it is very crowded.

1. Today, as in every other day of the year, more than 3,000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3,000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised. First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors exceeded that among female by nearly 10 percent. The statistic is reversing. Third, several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent . Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking levels among youth. 1. According to the author, the deaths among youth are mainly caused by _____. A. traffic accidents B. smoking-related diseases C. murder D. all of these 2. Every day there are over _____young people who will become regular smoker. A. 75 B. 23 C. 30 D. 3,000 3. By "dropout" (in paragraph 3) the author means______. A. students who failed the examination
