2 . A giant dam was built many years ago to control the Colorado River in the U.S. This dam was built to protect the land and houses around the river.
This huge dam is in the Black Canyon. It is possible to drive a car from one side of the river to the other on a road, which is on the top of the dam. This dam is so big that there is an elevator inside. The elevator goes down forty-four stories from the road to the bottom. There is enough concrete in this dam to build a highway from New York to San Francisco. Thousands of people worked on this dam for five years.
This huge dam was called Boulder Dam when it was finished in 1936.Later it was renamed Hoover Dam in honor of a president of the United States. Hoover Dam, one of the highest dams in the world, is situated between the states of Arizona and Nevada.

3 . Would you BET on the future of this man?He is 53 years old. Most of his adult life has been a losing struggle against debt and misfortune. A war injury has made his left hand stop functioning,and he has often been in prison. Driven by heaven-knows-what motives,he determines to write a book.
The book turns out to be one that has appealed to the world for more than 350 years. That former prisoner was Cervantes,and the book was Don Quixote(《堂吉诃德》). And the story poses an interesting question: why do some people discover new vitality and creativity to the end of their days,while others go to seed long before?
We’ve all known people who run out of steam before they reach life’s halfway mark. I’m not talking about those who fail to get to the top. We can’t all get there. I’m talking about people who have stopped learning on growing because they have adopted the fixed attitudes and opinions that all too often come with passing years.
……
What does the underlined part in Paragraph 3 probably mean?
A.End one’s struggle for liberty. |
B.Waste one’s energy taking risks. |
C.Miss the opportunity to succeed. |
D.Lose the interest to continue learning. |
4 . Invited by Mr. Ye Huixian, host of the well-received TV programme "Stars Tonight", Miss Luo Lin, Miss Asia of 1991, appeared as the guest hostess on the Shanghai TV screen last Sunday.
Born in Shanghai and taken to Hongkong when she was only six years old, Luo Lin has never dreamed of being Miss Asia. Her childhood dream was to be an air hostess. Before she took part in the competition, she had been an airhostess in Cathay Airline for seven years. However, it still took her three months to learn the art of walking on the stage, dancing, singing, making-up and other proper manners, designed by the Asia TV Station.
"It’s really a hard job for me. I won’t enter for such competition any more. Anyhow, I am quite lucky. I am also glad to have had more chance to work for the social welfare since I won the title. This time, in Shanghai, I’d love to make a deep impression on my TV audience," said Luo Lin with a sweet smile.
Q:Which of the following is NOT true?
A.Luo Lin is a native of Shanghai. |
B.Luo Lin moved to Hongkong with her parents. |
C.Luo Lin won the title of Miss Asia in 1991. |
D.Asia TV Station helped Luo Lin to become Miss Asia. |
Plants can also detect volatile compounds produced by other plants. A tree under attack by Hungry insets, for instance, may give off volatile compounds that let other trees know about the Attack. In response, the other trees may send off chemicals to keep the bugs away ——or even Chemicals that attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying: a chemical Sensor(传感器)called an electronic nose. The “e-nose” can tell compounds that crop plants make When they’re attacked Scientists say the e-nose could help quickly detect whether plants are being Eaten by insects. But today the only way to detect such insects is to visually inspect individual Plants. This is a challenging task for managers of greenhouses, enclosed gardens than can house Thousands of plants.
The research team worked with an e-nose than recognizes volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds Based on these interactions, the e-nose gives off electronic signals that the scientists analyze using computer software.
To test the nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all common greenhouse crops. Then scientists collected samples of air around damaged leaves from each type of crop, These plants had been damaged by insects, or by scientists who made holes in the leaves with a hole punch(打孔器). The e-nose, it turns out, could identify healthy cucumber, pepper and tomato plants based on The volatile compounds they produce, It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage ---- by insects or with a hole Punch ---- had been done to the tomato leaves.
With some fine-tuning, a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareva, a biochemist at Purdue University in West Lafayette, Ind. who studies smells of flowers and plants. Hopefully, scientists believe, the device could bring large benefits to greenhouse managers in the near future.
