A CPU is similar to a calculator, only much more powerful. The main (1) function of the CPU is to perform arithmetic and logical operations on data taken from memory or on information entered through some device, such as keyboard, (2) scaner, or joystick. The CPU is (3) controlled by a list of sortware instructions, called a (4) computer program. Sortware instructions entering the CPU originate in some form of memory storage device (5) such as a hard disk, floppy disk, CD-ROM, magnetic tape. These (6) instructions then pass into the computer's main random access, (7) memory (RAM), where each instruction is (8) given a unique address, or memory location. The CPU can access specific pieces of data in RAM by (9) specifying the address of the data that it (10) wants.

Mình cho bạn cả bài nhé chứ như thế này rối lắm:

Have you ever followed instructions for knitting something or have you read a piece of music? If you have, you have behaved in a similar way to a computer. A computer obeys a program to carry out a particular task. Just as a knitting pattern is expressed in numbers and piece of music in lines and dots, so a computer program is expressed in the form of programming language. Like the English language (or any other language), there are rules of grammar, and a program must be correct in every way.
There are hundreds of programming language, but only a few are well-known and widely used. The most popular language which is used in offices is called Cobol. This language is used for printing payrolls and keeping records of goods. Engineers and scientists use Fortran in order to carry out calculations. However neither of these two programs is very popular with people working on home computers. Basis is the most popular language for home computers, chiefly because it is easy to learn and use.
Although these languages are useful for many purposes, it is time that a new simple program was devised. Such a program ought to be not only easy to use but also completely reliable.

Read the passage below and decide whether the statements are TRUE or FALSE?

We are all around computers. Computers play an important play in our day to day lives, like we are very much dependent them for doing many things including giving users the ability to quickly and easily store and process data. Since the invention of computer they have evolved in terms of increased computing power and decreased size. Computers are used in many sectors like Education, Health and Medicine, Financial Institutions, Transport System, E-Commerce, Defence etc.

Computers connect us to the world of unknown. They help us gathering knowledge and huge information from the internet and storing it. Computers are multitasking and accurate enough to be used almost anywhere and everywhere including banks. Computer provide security from destructive forces and from unwanted action from unauthorized users like cyber attack or access attack.

Now computer is not just a calculating device, it has become much more than that. One of the main advantages of computer is its incredible speed, which helps human to complete their task in few seconds. All the operations can be performed very fast just because of its speed else wise it takes a long time to perform the task.

Question: Computers provides prevention against cyber attack or access attack.

A. True

B. False

Read the following passage and choose the correct answer to each questions.

Your mind's ability to bring back experiences you have had is your memory. There are two kind of remembering, recall and recognition. For instance, you may not be able to recall the poem you read yesterday in class, but if you see it again, you will know it instantly because you recognise it.

Some few people have "total recall", often spoken of as photographic memory. A person with total recall can recite a whole page of a book he has read only once, or play a musical composition after hearing it once. This is very unusual, however, and most people have difficulty in remembering even the names they heard the day before. This is not because most people lack the ability to remember, but because they had not paid much attention to what they heard. They felt no personal reasons to remember. Having a personal reason for remembering is one of the most important factors in a good memory.

When you have a strong reason for remembering, concentrate as you read or listen, and try to connect the new information to things you already know. A detail is easy to remember when it fits into a whole that make sense. If you understand the entire history lesson before you try to remember any particular dates, your memory may surprise you.

1. One way to improve your memory is __________.

A. to ask other people to repeat something again and again

B. to have a camera with you all the time

C. to concentrate on what you listen or read

D. to learn everything you read or hear by heart

2. This article as a whole tells us about __________.

A. people who can remember whole pages

B. people who can’t remember names

C. your memory and how you may improve it

D. recognition as one way to remember things

3. A person with photographic memory __________.

A. can only remember things if he looks at a photograph

B. can remember every detail of what he sees or hears

C. can be found in mental hospitals

D. brings his camera everywhere he goes

4. Which of the following is NOT true according to the passage?

A. Most people lack the ability to remember.

B. Recognition and recall are the two kinds of memory.

C. Your memory is your ability to bring back experiences you had.

D. A person can remember things better if he has a strong reason for doing it.

5. While not directly stated, it may inferred from the article that __________.

A. details are more easily remembered than the whole

B. recall and recognition are the same

C. if one tries hard enough, he can remember as well as another

D. wanting to do a thing is very important to being able to do it
