Antifreeze is a liquid(液体) that is added to water to keep it from freezing． When water freezes and turns to ice，it expands(膨胀)．The force of water expanding is so great that it will break the hardest metal．Water is used in car engines(发动机) to keep them cool while they run，and if this water is allowed to freeze in winter it can break the iron block of the engine．That is why antifreeze is necessary．

Water freezes at 0℃；the usual kind of antifreeze will not freeze until the temperature is－40℃．A mixture(混合物) of five parts of water and four parts of antifreeze will prevent freezing at－18℃；four parts of water and five parts of antifreeze reduce this to －22℃．

Alcohol is a kind of good antifreeze，but when the air is running it becomes hot and the alcohol boils away，so it must be changed very often．Most people use antifreeze that does not boil away when the engine is running．There are several chemicals that do this．One of the most popular is called ethylene glycol．

Mr. and Mrs. Smith have just opened a small restaurant. In order to attract customers, they put a notice in front of the restaurant, which said: “Meals on the house for three days.”

A foreign student who didn’t know much English passed by the restaurant on the second day. It was lunchtime and he felt hungry. “Well, here is a restaurant. I’m going to have something to eat,” he said.

He saw the notice when he walked towards the restaurant. “American people are really strange. They even eat dinners on the house! But how can I get onto the top of the house?” he asked himself.

He looked around and found a ladder（梯子）against a tree nearby. He was very glad. But as he reached the top, he heard someone shouting at him: “Hey, what are you doing up there?” Mr Smith was looking at him angrily. Beside him was a policeman.

“Doesn’t your notice say ‘Meals on the house for three days’? Is it just a joke?” the foreign student answered.

On hearing this, both Mr Smith and the policeman burst into laughter(开怀大笑). “Do you know what On The House means?”

You want to know about my staying in America, right? Well, to tell you the truth, it is really an eye-opening experience to study here.

In China, I had English classes five times a week since the fifth grade. ①However, I didn't know how different textbook English could be from everyday English until I came to Hotchkiss School, Connecticut.

When I first studied English, I was told to say "I am fine." when people say "How are you?" But in the US, I found that people say, "I am good." or "I'm tired."

One day, someone greeted me with "What's up?" It made me confused. I thought for a moment and then smiled because I didn't know what to say.

Since then, I have discovered more and more differences between Chinese and US cultures.

To my surprise, US girls spend a lot of time in the burning sun to get a tan. However, in China, girls try every possible way to get their skin paler, or "whiter".

I was also surprised by how hard-working US students are. In China, schoolwork is almost everything, so we study hard and that's it. But here, a "good" student gets good grades, does a lot for the public and plays sports or music.

The kids here are so talented. ②I am starting to be sorry that I gave up playing the piano at an early age and that I have never thought about sports.

1.According to the writer, textbook English is everyday English.

A. quite different from B. the same as

C. more different than D. easier than

2.What does the word "tan" in the sixth paragraph mean in Chinese?

A. 晒黑 B. 晒白 C. 能量 D. 热量

3.A good US student spends his / her time_______.

A. only in doing homework

B. only on sports or music

C. on studies, sports or music and public work

D. on public work

4.Which is the best title for the passage?

A. My Own Travel in the US B. My Studying in the US

If you have a brother or sister, you already know you are different from each other. You live together in the same house and have the same parents, but you have different personalities.

Why is this? One possible reason is the way your parents treat you. First-born children receive all the attention from their parents. Most families have twice as many photos of a first-born than any other child. Parents usually give first-born more responsibility and depend on them to take care of younger brothers and sisters. As a result, first-borns are often responsible, hard-working, andjealous. They often want to do well at school and work. There are more first-born American Presidents, for example, George Bush, George Washington, and Lyndon Baines Johnson-than second or last-born children.

When a second child arrives, parents are more relaxed. The second child has to compete with the first-born for the parents’ attention and love. Their children often choose different sports and hobbies to do well at school and work, but have to be creative to get their family’s attention. They are often friendly and cool. Many famous talk-show hosts were born last.

1.The writer thinks that the second children are often ______.

A. outgoing and jealous B. cool and friendly

C. hard-working and serious D. creative and responsible

A. 友好的 B. 冷静的 C. 快乐的 D. 嫉妒的

C. it’s easy for the second child to get his or her parents’ attention

D. there are more first-born successful people than second or last-born people
