Most Americans take pride in inviting guests with open arms. What should you do if an American friend has invited you to visit his family? You've never been to an American home before, and you're not sure what to do. Should you take a gift? What time should you arrive or leave? How long should you stay? Take it easy. I’ll tell you all about it.
The question of whether or not to bring a gift often worries guests. Giving your host a gift is not just a social custom in some cultures—it's expected. But in American culture, a guest does not have to bring a gift. Of course, some people do bring a small gift for their host. Proper gifts might usually be flowers, candy or—if the family has small children—toys. If you choose not to bring a gift, don't worry. No one will even notice.
Plan to arrive on time, or call to tell your host that you will be late. When you've finished the meal, the host may invite everyone to move to the living room for dessert with tea or coffee. After an hour or so, it's about time to head for the door.
Americans usually like to invite guests ahead of time. Only very close friends visit the host unexpectedly without being invited. This is especially true if the guests want to stay for a few days. Here's one golden rule for house guests: short stays are best. Even relatives don’t usually stay for several weeks at a time. Your host family will appreciate our consideration (体贴), and they may even invite you back!

Sometimes, you do not finish drinking your glass of water before you go to bed. 1.
But have you ever wondered if it is still safe to drink?
“If you have clean water in a clean glass, you’re fine to drink it for a day or two,” Kellogg Schwab from the Johns Hopkins University Water Institute in the US told Time.
2. That’s because after about 12 hours, the carbon dioxide (二氧化碳) in the air reacts（反应）with the water in your glass, slightly lowering its pH level.
Also, there might be more microorganisms (微生物) in your water if you leave it out overnight. Microorganisms grow more quickly at room temperature. These microorganisms can stay on your glass. 3. But as long as you clean your glasses very often, this will not be a problem.
In countries like the US and UK, people often drink water directly from the tap (水龙头).4. Most experts say that tap water has a shelf life of six months, according to Zane Satterfield from West Virginia University, US. After six months, there is less chlorine (氯) in the water and bacteria (细菌) start to grow. You’d better not drink the water otherwise you may get sick.
5. Schwab said people should be careful with them. If you leave a bottle of water under the sun or in a car for a long period of time, the plastic produces a chemical called BPA. This chemical can cause heart disease and cancer.
A.What about plastic water bottles?
B.They can make you get sick more easily.
C.Is it safe for you to drink the water later?
D.But you may find that it tastes strange.
E.Some people prefer to drink water from rivers.
F.You might want to drink it the next morning.
G.This is OK—however, tap water cannot be stored for a long time.
George Washington Carver had a goal. This was to help southern farmers who needed good crops. They needed crops that didn’t hurt the soil. Carver went to Simpson College in Iowa, in which he studied for three years. Then he went to Iowa State, where he got two degrees. The college knew he was smart and wanted him to stay. So he joined the team. He was put in charge of a huge greenhouse. There he grew over 20,000 kinds of fungi（真菌），which made him famous.
Carver had many job offers. Thomas Edison offered $175,000 a year. Henry Ford tried to hire him too. Joseph Stalin invited him to the Soviet Union to help with cotton. But Carver refused all offers. Instead, he took a job at Tuskegee Institute. This was a school for African Americans. Carver was paid only $1,000 a year. But he was happy because he had goals to reach and he knew he could reach them at Tuskegee.
Carver worked at Tuskegee for 47 years. He never asked for a raise in pay. And he never received one. He worked so hard that he died in his office chair on January 4, 1943.
Carver came up with over 300 products from peanuts （花生）, all of which could have been patented (申请专利). He could have made millions. But he did not want to. Here is what he said, “Mr. Creator did not charge to grow the peanut. I cannot accept money for my work with it.”
Through his efforts, Carver set up a fund, for he wanted research to continue. He gave his life’s savings to it, which came to $40,000. One honor came after his death. His birthplace was made a national shrine (圣地). How surprised the modest Carver could have been!
1.One job offer which Carver accepted was to work for ______.
A.Thomas Edison B.Henry Ford
C.Joseph Stalin D.Tuskegee Institute
2.How much did Carver offer to the fund？
A.$1,000. B.$20,000.
C.$40,000. D.$175,000.
3.Which of the following best describes Carver?
A.Selfless. B.Stubborn.
C.Stupid. D.Reliable.
4.What’s the main idea of the text?
A.Carver preferred work to money.
B.Carver devoted his whole life to achieving his goals.
C.Carver refused many job offers that would make him rich.
D.Some scientists would rather do good than make much money.
