Giup e với . Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions. Cell phones are an integrated part of our society at this point, and their main use is communication. They keep students in touch with the rest of the world by giving them the power to interact with it . In my day, if you forgot your lunch you were at the mercy of the office calling home for you. Now, students have the ability to solve their own problems and handle certain "emergencies" on their own. Cell phones also allow students the ability when the time is right, to keep in touch with students at other schools or friends that don't go to school. While not an educational benefit directly, better relationships can lead to higher self-esteem and reduce isolation, which is good for everybody. In the same way, camera phones allow students to capture the kinds of memories that help build a solid school culture, and, in some cases, can act as documentation of misbehavior in the same way that store cameras provide evidence and deter bad behavior. Academically, the cell phone can act as to record video of a procedure of explanation that may need to be reviewed later. It could be used to record audio of a lecture, as well, for later review. And just imagine if class could be easily " taped " for students who are absent? What if they could even be streamed and seen from home instantly? The iPod is a little trickier, because its function varies greatly by model. At its heart , it is a media player, and I know for a fact that many students work better while listening to music. For this reason, they can have a good effect by keeping students from getting too distracted while working ( ironic , because we mostly think of them AS distractions!). If it is a WIFI compatible model, and wireless internet is available, the iPod can be a great tool for looking up information or digging into things more deeply. Depending on the model, it may be able to act as a camera and video recorder as well (with the same benefits as the cell phone). Devices like the Kindle could, conceivably, make learning a lot easier. Imagine carrying all your textbooks in the palm of your hand, rather than strapped to your back! Though expensive, compared to buying new textbooks, the Kindle is a bargain. Many of the books used in high school English classes are actually FREE on the Kindle. 11. The passage mainly discusses ____. A. how some electronic devices are used in education B. how to use electronic devices in the classroom C. what is the best electronic device used in education D. which electronic device will be used as the textbooks 12. The word " it ' in the passage refers to ____. A. the power B. the world C. the rest of the world D. the main use 13. The phrase " at the mercy of " mostly means ____. A. completely dependent on B. at request of C. thankful to D. under orders 14. According to the passage, cell phones do NOT ____. A. help students keep in touch with their friends B. allow students to capture of memories C. help students record audio of a lecture D. enable students to write their assignment 15. The word " which " in the passage refers to ____. A. building better relationships B. achieving higher self-esteem C. that relationships lead to higher self-esteem D. having higher-esteem and lower isolation 16. Which of the following is closest in meaning to the word " taped "? A. recorded B. reviewed C. streamed D. seen 17. The phrase " At its heart " mostly refers to ____. A. the main function B. the core part C. the central unit D. the best usage 18. The word " ironic " is closest in meaning to ____. A. lucky B. special C. funny D. particular 19. Which of the following is NOT true about the iPod according to the passage? A. The iPod can be used to make phone calls. B. The iPod can be connected to the Internet. C. The iPod can be used to record videos D. The iPod comes in different models. 20. Which of the following is true about the kindle according to the passage? A. The Kindle is more economical than new textbooks. B. Everything read on the Kindle is free of charge. C. The Kindle comes in different models as the iPod does. D. You cannot listen to music with a Kindle

VIII. Read the following passage and mark the letter A, B, C or D on year answer sheet to indicate the correct answer to each of the questions. 

    Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication- having a mobile phone shows that they are cool and connected.

      The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

     On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a travelling salesman had to retire at young age because of serious memory loss. He couldn’t remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, evey day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer’s doctor didn’t agree.

     What is it that makes mobile phones potentiallyharmful? The answer is radiation. High-tech machines can detect very small amounts of radiationfrom mobile phones. Mobile phone companies agree that there is some radiation. But they say the amount is too small to worry about.

      As the discussion about their safety continues, it appears that it’s best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it’s wise not to use your mobile phone too often.
