IV. Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the best option to answer each of the following questions. Did you ever wonder why it is so difficult for adults to start to learn English or a foreign language? Every year, millions of grown-ups around the world spend a large amount of money on learning English but not many of them succeed in becoming fluent English speakers. This is because it is not easy to pick up a new language after a certain age. However, small children learn foreign languages without much difficulty. This is because they have a special ability that helps them learn languages fast. This ability weakens when people grow older. Think of the little time children need to learn their native languages. Therefore, if you have the desire to learn English or any other foreign language, you should begin as soon as possible. Remember that the longer you wait, the harder it will become. Câu 10.

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the best option to answer each of the following questions. More than 80% of American high school students work at part-time jobs in the evenings, on weekends or in summer. These part-time jobs bring teenagers great advantages. One of the benefits of the work is the students can learn the skills that will be useful for the school work. To be able to do so, they must be very organized and able to keep a sensible schedule. They also learn to cope with the job stress apart from the stress of the school work. Some of the most stressful jobs include teaching, nursing, and police work. These skills help prepare teenagers for the latter careers. High school students who work are more likely to succeed as adults than people who enter the job market at a later age with no work experience. Teenagers want a lot of expensive things: clothes, mp3 players, trips with​ their friends, etc. Not all parents can afford them. And even if they can, the teens might not really appreciate that money because they did not earn it. When teenagers make money for themselves, they know its true value and are less likely to spend it foolishly. Câu 15. What is the mam idea of the passage? A. Part-time jobs cause stress​B.
