chỉ cần đọc rồi khoanh thôi mà b. Read the passage and choose the best answer A, B, C or D I’m interested in sports, especially athletics, and I run seven or eight kilometers every day. I particularly enjoy cross country running, where you have to run across fields, jump over streams and so on.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions. During the teenage years, many young people can at times be difficult to talk to. They often seem to dislike being questioned. They may seem unwilling to talk about their work in school. This is a normal development at this age, though it can be very hard for parents to understand. It is part of becoming independent of teenagers trying to be adult while they are still growing up. Young people are usually more willing to talk if they believe that questions are asked out of real interest and not because people are trying to check up on them. Parents should do their best to talk to their sons and daughters about school work and future plants but should not push them to talk if they don't want to. Parents should also watch for the danger signs: some young people in trying to be adult may experiment with sex, drugs, alcohol, or smoking. Parents need to watch for any signs of unusual behaviour which may be connected with these and get help if necessary. Question 28: Why do adults sometimes find teenagers difficult to talk to…. A. because most teenagers are quiet B. because teenagers don't want to talk to other people. C. because teenagers think adults are not honest D. because most teenagers hate adults. Question 29: When can you expect young people to be more talkative than usual. A. When people talk to them because they are really interested and not just checking on them? B. When adults give them a lot money to spend. C. When adults talk to them about something other than their work in school. D. When adults talk to them about sex, alcohol and drugs. Question 30: Some teenagers experiment with drinking bad smoking because A. cigarettes and alcohol are available everywhere. B. cigarettes and alcohol are cheap C. women like smoking and drinking men D. they regard them as a mark of adulthood Question 31: The word BEHAVIOUR in the passage most nearly means A. feeling B. manners C. activities D. reaction Question 32: This passage is taken from a… A. handbook for parents B. school timetable C. teenage magazine.
