These days, cars are designed using computers. Let’s look at how a new car is created.
First, several designers talk about the new car and any good ideas that they have. Then they sit down at their computers and draw many sketches. The best two or three drawings are chosen and then more detailed(细节的,详情的) drawings of cars are developed on the computer. You can change the size, shape or color of any part on the computer to see how the car would look and then (73 ) you can choose the best design.
Both the inside and the (71) ________of the car have to be designed. Part of the inside of the car is built so that the designers can sit in it. They can feel if there is enough room inside and if they can reach everything. Then some cars are built—there are more than 15 000 parts of a car to test.
(74) When everything is safe, the cars are made in the factory. Again, computers are used to make sure that all the parts are ready as they are needed. (72)The factory usually stays open all through the night so that the car production never stops.
【小题1】Fill in the missing word:
“Both the inside and the _____________of the car have to be designed.”
【小题2】The underlined phrase “stays open” means______________________. (Only in English)
【小题3】“You can choose the best design.” means:
The best design can __________  __________.
【小题4】Please translate the following sentence into Chinese:
“When everything is safe, the cars are made in the factory.”
__________________________________________________________________________
【小题5】The main idea of the passage is
____________________________________________________________________.

The human brain weighs about 1.4 kilograms, but it can hold much more information than most computers. However, there is another difference between humans and computers. Computers don't forget information they are given, but humans often do. No one remembers everything, and luckily we don't usually have to. But everyone can improve their memory if they want to. Here are some suggestions.

◆Try to use new informati6n immediately. For example, if you meet someone who says "Hi! I'm Carlos," don't just say "Hello." Repeat the person's name. Say"___________"

◆Break a big number into smaller parts. For example, it's hard to memorize (记忆) 109244153. But if you break it into three parts--109/244/153—it becomes easier.

◆Write out what you need to remember ever and over again. This will help you keep it in mind longer, especially for memorizing formulas (公式) or facts.

◆Always review information. If you bring what you've learned back to your mind, they become easier to remember. For example, before you go to sleep, it’s a good idea to review the new things you learned that clay.

◆Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what's right and what's wrong, and it will lead to the right answer.

◆Never tell yourself that you have a bad memory. You can always do something to help improve your memory. And everyone's memory gets better if they use it often enough.

All of the suggestions are helpful. If you follow them, you are certain to improve your memory.

A. Hello, Carlos. B. How do you do?
