SECTION 2: VOCABULARY, GRAMMAR, AND READING Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks from 11 to 15. Dear Sunday Globe, I am writing to you about your article in last Sunday's newspaper, "Cell Phones Make Life Easier." You did an excellent job explaining the good points of cell phones: they're convenient, we feel safer always being able to call someone; and they are very helpful in business. On the other hand, you didn't talk about their bad points at all. I hope you'll let me give your readers some advice on cell phone etiquette. The first point I'd like to address is when not to use your phone. It's polite to switch off your phone or turn off the sound when you're in class or in a meeting. If you get an important call, you should ask for permission to leave the room and then don't talk for too long. Furthermore, for conversations that need more time, it is best to ask the person to call back at a more convenient time. Cell phones can also cause you to neglect the people you are with. I find it really annoying when my friends constantly check their 0 messages on their phone. In fact, I want to tell them to turn off the cell phone and enjoy my company! vl Another point that needs to be made has to do with personal space. I think it is very impolite to make noite calls in small spaces or crowded rooms. This makes others uncomfortable and forces them to listen toonibn your personal conversations. Additionally, it disturbs other face-to-face conversations; that's why I neverbo use my cell phone within a few meters of other people except in emergencies. Lastly, I would like readers to pay attention to the dangers of using your phone while doing something e else. For instance, driving and texting is a bad combination. Likewise, using your phone or texting when que walking can make you careless. You don't want to get hit by a car. Pay attention to where you're going!vlvenn Sincercly, Amber Jala 1.Why did Amber decide to write this letter? 2.which advide is not INCLUDED in Amber's first point? 3.what does the pronoun "This" refer to in garagraph 2? 4.which of the following summarizes the THREE major point Amber make in her letter? 5.
