America is a mobile society. Friendships between Americans can be close and real，yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two，perhaps a few letters for a while— then no more. If the same two people meet again by chance，even years later，they pick up the friendship. This can be quite difficult for us Chinese to understand，because friendships between us develop more slowly but then may become lifelong feelings，extending (延伸) sometimes deeply into both families.

Americans are ready to receive us foreigners at their homes，share their holidays，and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives，they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes，we，as hosts，will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans，however，express their welcome usually at homes，but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes，the welcome will be full，warm and real. We will find ourselves treated hospitably.

    For the Americans，it is often considered more friendly to invite a friend to their homes than to go to restaurants，except for purely business matters. So accept their hospitality at home!

  Height is just one of the thousands of features your genes decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out.

But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.

No doubt you're wondering how fast you should grow. It depends. There's no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up).

Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you're at now, how you've been growing up to this point, and what other changes your body may be going through.

Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt（高峰）during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later ----between 7 and 13 for girls and 9 and 15 for boys.

You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty. 

1.. The Chinese for the word “puberty” is 　　　　　　　　　.

   A. 童年时期          B.婴幼儿时期        C.习惯养成期        D. 生长发育期

2. If you want to know how fast and how tall you should grow, _____.

   A. you should have enough exercise   B. you can ask doctors for help

   C. you should save the environment   D. You can record your growth during puberty

3. This passage is mainly about 　　　　　　　　　.

   A. how the genes work in your body           B. when is the time you grow fast

   C. why you look like your parents                D. how you grow to a certain height 

4. After reading this passage, we can explain 　　　　　　　　　.

   A. how good it is to be a doctor             B. how much sleep time we need

   C. why genes can’t decide everything            D. what healthy diet is

5. Which is NOT mentioned in the passage?

   A. Your height most probably depends on how high your parents are.

   B. Girls’ age for starting puberty is usually earlier than that for boys’.

   C. The time showing the first changes of puberty is never noticed.

   D. You may be scared sometimes when you grow too fast.

What do you do if you're stranded（处于困境的）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 fire 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 to 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 to 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 pilots flies the plane in a clockwise circle, this means "message received but not understood".(At night, the pilot flashes the plane's red lights.)

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

 

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

 

 

　

 

2. 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.

　　3. What is the passage mainly about?

　　A. The explanation of building signals on an island.

　　B. The importance of making signals on an island.

　　C. Ways of sending out signals on a lonely island.
