The health problems about cloned animals , particularly those who appear healthy but have hidden illnesses or problems that appear unexpectedly later in life, have the potential to cause real risks to the safety of the food products from those animals. Ian Wilmut, a lead scientist involved in the creation of Dolly, the first cloned animal, has warned that even small imbalances in a clone’s hormone, protein, or fat levels could bring its milk or meat into danger.

As part of its risk assessment on animal cloning, the Food and Drug Administration (FDA) concluded that milk and meat from cloned animals and their offspring (后代)are as safe to eat as products from conventional animals. The FDA further announced that it would not require food products from cloned animals or their offspring to be labeled as such.

Consumer watchdog groups pointed out that the FDA’s analysis was based on limited data supplied mainly from the cloning companies themselves. In addition, while food safety is an obvious concern of consumers, it is not the only issue that makes people uncomfortable with animal cloning. For example, surveys indicate that 63 percent of consumers would not buy food from cloned animals even if it were labeled as “safe”. Concerns about the morality of cloning, as well as concerns for animal welfare, lead a big majority of people to oppose cloning animals for food. However, these issues were not considered by the FDA. Without labels to identify cloned foods, consumers who oppose animal cloning would be forced to make purchases against their principles without knowing. Consumers have a right to know how their food is produced so they can make informed decisions about what they buy and what they feed their families.

1.What is Ian Wilmut’s attitude towards food products from cloned animals?

A. Approving. B. Cautious.

C. Uncertain. D. Indifferent.

2.What does the underlined word “such” in Paragraph 2 refer to ?

A. Safe. B. Expensive

C. Unsafe D. Conventional.

3.We can learn from the last paragraph that _____.

A. consumers didn’t believe what the FDA said

B. the FDA took consumers’ concerns seriously

C. consumers were well-informed about the safety of food

D. the FDA forced consumers to buy things they didn’t want

4.What is the main idea of the text?

A. Concerns for animal welfare.

B. The problems with animal cloning.

C. Why people are uncomfortable with animal cloning.

D. Concerns about the food products from cloned animals.

Dos and Don’ts for USA Travel

Despite what difficult procedures (程序) you may have endured to get to the U.S., including visa troubles, airport security screenings, and the like, the United States is a rather relaxing place once you arrive. 1. Following are basic tips about traveling in the USA.

Don’t try to see and do too much.

2. Many foreign visitors to the United States try to see New York, Washington DC, Miami, and Los Angeles all in one trip. That kind of touring can leave a traveler very tired if you have limited vacation days. The best way is to focus on a region and more deeply.

3.

While traveling in the United States, do be sure to smile, ask questions, say “please” and “thank you”, and be patient. In almost all cases, your kindness will be rewarded by locals who want to show you the best of their cities and towns.

Do obey traffic signs and laws.

Traveling outside of the United States, I have noticed that stop lights and “No Parking” signs in some parts of the world are only suggestions for drivers. Not in America. Drivers must come to a full stop at a red light and remain stopped until the light turns green. 4.

Do be on time.

America take punctuality very seriously. 5. Give yourself more time than you think you’ll need to get to some place, especially if you’re not familiar with the area as unexpected delays can happen, such as heavy traffic.

A. It is considered rude to be late.

B. Besides, drivers should obey the speed limit.

C. Do be kind, smile, and enjoy yourself.

D. Don’t assume you can smoke anywhere.

E. The United States is larger than Europe.

F. Try to use the vocabulary they use in their everyday life.

G. But we do have a few rules that foreign visitors may not know about.

On a freezing afternoon, I picked up a wallet in the street. There was no identification(身份證) inside. Just three dollars, and an old letter that looked as if it had been carried around for years. I opened the letter and saw that it had been written in 1924——almost 60 years ago！ I read it carefully, hoping to find some clue(線索) to find the wallet’s owner.

It was a “Dear John” letter. The writer, in a delicate script(娟秀的字跡),told her lover, whose name was Michael, that her mother did not allow her to see him again. It was signed Hannah and her phone number. So I called.

“No, of course! We bought this house from Hannah thirty years ago. Hannah had to live in the nursing home many years ago. Maybe you can go there.”

Then I phoned the nursing home and was told, “Yes, Hannah is with us. Hannah was a sweet, silver-haired old-woman with a warm smile and friendly eyes. ”

I went up to the third floor of the nursing home. I showed her the wallet and the letter. The moment she saw it, she took a deep breath. “Young man,” she said, “this letter was the last contact I had with Michael. ” She then said deeply: “I loved him very much. But I was only sixteen and my mother felt I was too young. I never did marry, I guess no one ever matched up to Michael...”I took the elevator to the first floor. As I stood at the door, holding the letter to the guard. He looked at it closely and said, “Hey, I know ,the letter is Mr. Goldstein’s. He’s always losing it.”

“Who’s Mr. Goldstein?” I asked. “He’s one of the old-timers on the eighth floor. That’s Michael Goldstein’s wallet, for sure.” We went there where Michael Goldstein was reading a book. I told him I know where Hannah is. He grew pale. “Hannah? You know where she is? How is she? When that letter came, my life ended. I never married. I guess I’ve always loved her.”

“Michael,” I said. “Come with me.” We three took the elevator to the third floor. We walked toward the Hannah’s room, still watching TV. Michael Goldstein went over to her. “Hannah,” he said softly. “Do you know me? Hannah, I’m Michael, Michael Goldstein. Do you remember?”

“Michael? Michael? It’s you!” He walked slowly and they embraced(擁抱) tearfully. A perfect ending for a love affair that had lasted nearly 60 years.

1.What do you think is the best title of the passage?

A. Forever Love. B. A Beautiful Girl.

C. Kindness and Chance D. A Great Story.

2. A “Dear John” letter is a letter for____________?

A. love B. marriage.

C. refusing D. party.

3.According to the story, we learned that___________.

A. when in Rome, do as the Romans do

B. Rome is not built in one day

C. All shall be well and Jack shall have Jill

D. Practice makes perfect

4.The writer's purpose of writing this story is to______

A. show how great and loyal the real love is

B. show where there is a will there is a way

C. prove what a surprise Hannah got

D. prove how they regretted to see each other.

Mark Twain was a great writer. He was from the USA. He was born in 1835. He was also a famous speaker. He was famous for his sense of humour. Many people liked to listen to him talk because he liked to tell some interesting stories to make people laugh all the time.

One day Mark Twain was going to a small town because of his writing. Before he was going to leave, one of his friends said to him that there were always a lot of mosquitoes in the town and told him that he’d better not go there.
