If you do not use your arms or your legs for some time, they will become weak, when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way.
When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents may be blamed(责备), and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories ? This is because they cannot read or write and they have to remember things, they cannot write them down in a small notebook. They have to remember days, names, songs and stories, so their memory is the whole time being exercised.
So if you want to have a good memory, learn from the people: practise remembering things in a way as other people do.
【小题1】Someone can’t have a good memory if ________.

Are your children liked by their teachers? All parents want their children to impress their teachers and succeed in school. You can get your children to impress their teachers by following these easy steps.
Make sure they’re prepared. Teachers are impressed by children coming to school prepared to learn. Make sure they have everything they need—pencils textbooks, erasers and so on.
Require them to be active in class. Teach them to ask teachers questions when they don’t understand something. Some children think teachers are bothered by questions, but most teachers are impressed when children take the initiative(采取主动) in asking questions. They should take part in class discussions, giving their opinions politely.
Keep your children healthy. If your children are tired and hungry, they won’t be ready to learn. Children need at least 8 to 10 hours of sleep per night. Feed your children a solid breakfast and prepare a healthy lunch. Provide them with fruit and other healthy foods—apples or bananas are better for them than cookies.
Make sure that your children do their homework. If they really don’t understand it, discuss it with them patiently. Don’t help them do their homework. Teachers can always tell who it is that does the work.
Teach your children good manners and habits. Children need to arrive at the school punctually, and be polite to their teachers and classmates. Parents need to teach these skills at home. Nothing is sweeter than children who say “please” and “thank you”,  and these are children their teachers are certain to love.

What do you do if you're in trouble on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.

Body signals (信号)

Pilots from different countries understand body signals if they have the correct training, When you wave your arms up and down in a straight line, it means, "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend (弯曲) your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.

Smoke signals

The smoke from a fire can be seen from far away, so it’s a good way to draw attention. If the weather is dry, it isn’t hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a tire unless you're sure that it can’t spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.

Ground-to-air signals

It's a good idea lo build some signals, too. Use large pieces of wood to make the symbols (标记). If you can't find any wood, use earth. Some useful symbols are:

F "I need food and water"

II "I need medicine."

I "I am badly hurt."

X "I am unable lo move from here."

Pilots' replies

If the pilot lowers the plane's wings from side to side, this means: "message received and understood" (At night, the pilot flashes the plane's green lights.) If the pilot flies the plane in a clockwise circle, this means "message received hut not understood" (At night, the: pilot flashes the plants red lights.)

However, there is no signal which means "message not received. Why not'?

1.How many signals can we use to draw the attention of the passing plane if you're in trouble?

  A. Three.        B. Four       C. Five      D. Six

2.Which picture means "it's not safe to land"?

3.What can we learn from the passage?

A. Swinging your arm from side to side means "yes"

B. If the ground is dark, light smoke can’t be seen.

C If you need some medicine, make a symbol “Ⅱ”.

D. The pilots make replies with a blue light at night.

4.What is the passage mainly about?

Do you want to make friends with others? Please remember to keep your words all the time. In this way, people around you will get along well with you.
To make friends and keep them, you have to keep your words. If you agree to meet someone at a certain time, you should arrive at the place on time or a little earlier. If you agree to help others, you must do it. Of course if there is something unexpected(没有预料到的) happening and you can’t do what you have agreed to do, your friends will understand this.
He is always lying or making excuses for breaking his words. Would you like to have him as one of your best friends? You wouldn’t. And your own friends feel the same way.
So, be more careful when you have to agree to do something for your friends. Don’t have “Maybe”in your mind when you say something about what you are going to do.
