King Hiero asked the crown (皇冠)-maker to make him a gold crown. But when the king got the crown, he wondered i1. the crown was entirely (全部地) made of gold. Then the king s2. the crown to Archimedes, the best scientist in the kingdom.

Archimedes thought about the p3. while a servant (仆人) poured some water into a bath for him. Archimedes got in the bath and some water came out of it, onto the floor. Archimedes was very e4.. “That’s it!” shouted Archimedes to the servant. “If we put an object (物品) in a pot full of water, some of the water will come out. The object displaces (取代) the water. A b5. object will displace a lot of water. A small object will displace a l6. water.”

Archimedes went to the palace to weigh the crown. It w7. one kilogram. He put the crown in a pot of water. Five centimetres of water came out. He then put one kilogram of gold in a8. pot of water. Three centimetres of water came out of this pot. Archimedes said to King Hiero, “Silver made the crown bigger. That is why the crown displaces m9. water. So, the crown is not made entirely of gold; it is made of both gold and silver.”

King Hiero was very a10. when he heard this, and he sent the crown-maker to prison.

Do you like to meet new people? Do you like to talk, or are you shy? Whatever your answers are, these tips can help you.

★Have some topics ready to start a conversation.

Say something about the weather or the place you’re in. Talk about the weekend we all have something to say about .

★Make the conversation interesting

Read the latest news. Read restaurant and movie reviews. Find out about the popular music or what’s new in fashion or sports.

★Be a good listener.

Keep eye contact（眼神交流）and say, “Yes,” “Hmm,” “Uh-huh,” “Right,” and “I know.” And say, “Really? That’s interesting.” It encourages people to talk.

★Don’t be boring.

Don’t just say, “Yes” or “No” when you answer a question. Give some interesting information, too.

★Don’t talk all the time.

Ask, “How about you?” and show you are interested in the other person, too. People love to talk about themselves! 

★Ask information questions.

Ask questions like “What do you do in your free time?” or “What kind of food do you like?” Use follow-up questions to keep the conversation going. But don’t ask too many questions, or it will be an interrogation! 

★Be positive

Those Negative comments can sound impolite. And if you don’t want to answer a personal question, simply say, “Oh, I’m not sure I can answer that,” or “I’d rather not say.”

科目：初中英語(yǔ) 來(lái)源：天津市和平區(qū)2019-2020學(xué)年九年級(jí)上學(xué)期期末英語(yǔ)試卷 題型：閱讀單選

Why Should We Learn Body Language

In English classes, we spend a large amount of time studying grammar and learning new words. We work hard to improve our reading and listening skills. Few of us, however, pay enough attention to body language. So body language is not important, is it?

The answer is, “Yes!” As the old saying goes, “Actions speak louder than words.” Sometimes, we can communicate things even without a single word. For example, shrug our shoulders (聳肩), and, without a word, we’ve just said, “I don’t know.”

Body language can help us stress what we are saying. It can help us express our true, inner feelings. Moreover, body language can help us find out if someone is lying. Often, people who are lying do not make eye contact (接觸). They may turn away or raise their shoulders because they are uncomfortable with the conversation.

In job interviews, the interviewers can sometimes judge the interviewee before he or she speaks. Body language is important in our personal lives, too. It can show if you really care about your friends. Leaning forward into the conversation, for example, means you are interested in what is being said. Listening without making eye contact means you are not paying attention but are waiting for your turn to speak.

Scientists have been studying body language for a long time. They say more than 70 percent of our messages are delivered (遞送)through body language. Sometimes, body language is more accurate (精準(zhǔn)的) than the words we use.

So it is very important for us to learn body language. By understanding body language, we are less likely to be misunderstood. We will find it easier to get a job. We will also have lasting friendships.

1.According to the first paragraph, in English classes, people do all of the following EXCEPT ________.

A.studying grammar B.learning new words

C.improving listening skills D.practicing using body language

2.According to the passage, in which of the following pictures is the woman saying, “I don’t know.”?

A. B. C. D.

3.According to the passage, people who are lying may ________.

A.learn forward B.make eye contact

C.raise their shoulders  D. shrug their shoulders

4.According to the author, body language can help us ________.

① get a job ② lie without anyone knowing

③ prevent misunderstandings ④ improve our English reading skills

A.①③ B.②④ C.①④ D.②③

5.By writing this passage, the writer mainly wanted to ________.

A.teach readers to understand body language

B.tell readers it is important to learn body language

C.show readers how to find out if someone is lying

D.help readers improve their English reading and listening skills
