“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.

We sometimes call the lion “the king of the jungle (丛林)” because it is stronger and more dangerous than other animals. It can run faster than many animals and it can hunt (捕猎) the best. It is the highest animal in the   21  food chain (食物链).[
In the sea, the shark is one of the animals at the  22  of the food chain. It can swim faster than most other sea animals, and it can use its big teeth to eat them.
What is at the top of the world’s food chain?  23  are! We are not the biggest or fastest, but we are the   24  We could not run faster than cheetahs (猎豹),  so we  25  cars and now we can move the fastest. We could not  26  better than lions, so we invented guns (枪). Now we can hunt the best.
People’s inventions are clever, but they can be dangerous, too. For example, people invented  27 , and now they make the air and rivers dirty. This can make   28  changes. Dirty rivers kill fish.  Then bears cannot eat the fish and the bears die. If we kill one part of the food chain,   29  also die. Remember that we are a part of the food chain, so we are in danger too! If we protect animals, we are protecting   30 ! We should and we could do something for the world!
