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

Computers are now an important part of human life. Without them, the modern world will stop: nobody will be able to travel, work, shop, watch TV, get money, or send messages.

However, together with computers come viruses - a kind of computer program. They move from one computer to another and damage the memory or other parts of the computer. Some viruses are difficult to stop; they can damage millions of computers in a very short time. The first virus called Brain appeared in 1986. In 1987, a more dangerous virus called Jerusalem appeared. It stayed in the computer and did nothing until the date was Friday 13th when it started to damage the computer's memory.

By the late 1990s, most computers were part of the e-mail and Internet systems. This meant virus programs could do a lot of destruction very quickly. The Melissa virus, for example, could move from one computer to another by e-mail - it automatically sent itself to every other email address in the address book.

In an effort to fight against viruses, programmers wrote antivirus software. Virus programmers are getting better all the time, but so is the antivirus software. However, a virus is always spread before a remedy takes action. People believe that one day a computer virus will bring the whole world to a stop for a few hours, which may paralyze many nations' government systems and cost the lives of many people who are traveling in a plane or undergoing an important operation.

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

In today's competitive world, what responsible parents would not want to give their children the best possible start in life? For this reason, many parents want their children, often as young as ten months old, to become familiar with computers. They seem to think that if their children grow up with computers, they will be better equipped to face the challenges of the future.

No one has proved that computers make children more creative or more intelligent. The truth may even be the opposite. Educational psychologists claim that too much exposure to computers, especially for the very young, may negatively affect normal brain development. Children gain valuable experience of the world from their interaction with physical objects. Ten- month-old babies may benefit more from bumping their heads or putting various objects in their mouths than they will from staring at eye-catching cartoons. A four-year-old child can improve hand-eye coordination and understand cause and effect better by experimenting with a crayon than by moving a cursor around a computer screen. So, as educational psychologists suggest, instead of government funding going to more and more computer classes, it might be better to devote resources to music and art programs.

It is ludicrous to think that children will fall behind if they are not exposed to computers from an early age. Time is too precious to spend with a "mouse". Now is the time when they should be out there learning to ride a bike. There will be time later on for them to start banging away at keyboards.

Câu 41: Why do parents want their children to learn how to use a computer from an early age?

A. Because they want their children to be well prepared for their future.

B. Because they are afraid their children will become competitive.

C. Because they believe their children will have difficulty learning to use one if they don't start early.

D. Because this is what all the other parents seem to do.

Câu 42: Children who spend a lot of time on their computers _________________

A. tend to like music and art more than those who don't.

B. tend to have more accidents than those who don't.

C. do not necessarily make more progress than those who don't.

D. will suffer from brain damage.

Câu 43: The author implies that children learn better _________________

A. when they hold and feel things around them.

B. after they have developed hand-eye coordination.

C. as they get older.

D. when they use a computer.

Câu 44: What would be an appropriate title for this passage?

A. Computers in schools B. Never too early to start

C. More computers mean brighter future D. Let kids be kids

Câu 45: What is true according to the passage?

A. There is no evidence that children who use computers are more clever than those who do not.

B. It is better for children to take computer lessons than art lessons.

C. Computers seriously harm children's eyesight.

D. Parents should not put off buying a computer for their children.

Câu 46: What does the word "ludicrous" in the third paragraph (first sentence) mean?

A. suitable B. sensible C. humorous D. ridiculous

Câu 47: What does the word “they” in paragraph 3 refer to?

A. time B. children C. computers D. mouses
