阅读短文,根据意思,判断所给句子的正误。正确的写T,错误的写F。

“How are you?” is a nice question. It’s a friendly way that people in the U.S.A greet(问候) each other. But “How are you?” is also a very unusual(不寻常的) question. It’s a question that often doesn’t need an answer. The person who asks“ How are you?” hopes to hear the answer “Fine”, even if the person’s friend isn’t fine. The reason is that “How are you?” isn’t really a question and “Fine” isn’t really an answer. They are simply (只)other ways of saying “Hello” or “Hi”.

  Sometimes, people also don’t say exactly(确切) what they mean. For example, when someone asks “Do you agree?”, the other person might think, “No, I disagree. I think you’re wrong...”But it isn’t very polite to disagree so strongly(强烈地), so the other person might say “I’m not sure.” It’s a nicer way to say that you don’t agree with someone.

  People also don’t say exactly what they are thinking when they finish talking with other people.For example, many talks on the phone finish when one person say “I’ve to go now.” Often, the person who wants to hang up(挂)says: “Someone’s at the door.” “Something is burning (烧)on the stove(炉).” The excuses(借口) might be real(真的), or not. Perhaps the person who wants to hang up simply doesn’t want to talk any more, but it isn’t polite to say that. The excuse is more polite, and it doesn’t hurt (伤)the other person.

  Whether they are greeting each other, talking about an idea, of finishing a talk, people don’t say exactly that they are thinking. It’s an important way that people try to be nice to each other, and it’s part of the game of language.

1.“How are you?” is another way of saying "Hello." or" Hi."

2.It is polite to say" No. I disagree. I think you are wrong, "if you don’t agree with others.

3.When someone says "I have to go now "On the phone,it means he wants to go on talking.

4."Someone is at the door." may be an excuse for finishing a talk.

5.Sometimes people don't say exactly what they are thinking about just because they try to be nice to each other.

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?
