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.

A.In 1986 B. In 1987 C. In 1990 D. On Friday 13th

43. Computer viruses became extremely dangerous _________.

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

COMPUTER HARDWARE

A computer needs both hardware and software to run, but decisions about the hardware must be made before you buy a computer. Understanding some basic information about the hardware is very important and will help you decide on the most suitable computer for you.

• Processors: The processor controls all of the activities of a computer. Processor speed is often shown in gigahertz (GHz). High processor speed means that your computer can run faster.

• Random Access Memory, or RAM: It is displayed in gigabytes (GB). The RAM shows how powerful your computer is. The more RAM in a computer, the more tasks your computer can do at the same time.

• Storage space: It shows how much information (such as documents, music, photos, etc.) a computer can store. It is also displayed in gigabytes (GB). There is other information about the hardware, such as the screen size, the battery, and the weight, that you need to know before choosing the best computer for you.

1. processor

a. shown

2. RAM

b. to keep something and use it later

3. displayed

c. the part of the computer that controls all other parts

4. storage space

d. a type of computer memory

5. store

e. the amount of information a computer can keep
