China in the 21st century is making great progress in space technology. In 2003, the country sent up the manned spacecraft Shenzhou-V. Four years later, Chang’e-I went into orbit (轨道) around the moon. In 2008 a Chinese man did the country’s first spacewalk.

These achievements would have been unthinkable without the contribution of Qian Xuesen, a key scientist on space programs and rocketry (火箭技术) of the People’s Republic of China. This pioneering scientist passed away in Beijing on October 31 in 2009 at the age of 98.

Once called “the father of our space industry”, Qian began working on China’s missile and space technology in 1956, when China had little technology. When asked by General Chen Geng whether the Chinese could develop their own missiles, Qian said Chinese could do anything that foreigners could.

His research helped lead to the explosion of China’s first atomic bomb (原子弹) in1964, as well as to its first man-made satellite in 1970 and its first manned spacecraft in 2003.

Qian was born in Shanghai. He graduated from Shanghai Jiaotong University in 1934.Then he studied in the US at the Massachusetts Institute of Technology and later at the California Institute of Technology. During World WarⅡ, Qian’s research contributed to the development of rocket technology that the US military (军队) began using in the 1940s. He was once prevented from leaving the country because it was decided that he knew too much about certain military matters. It was not until in 1955 that Qian returned to China with the help of the late premier Zhou Enlai.

“I plan to do my best to help the Chinese build a nation where they can live with dignity (尊严) and happiness, ” Qian told reporters before sailing for China in 1955. The great scientist devoted all his life to keeping the promise.

1. What is the article mainly about?

A. It gives a short history of Chinese missile and space programs.

B. It is about how Qian contributed to the Chinese space program.

C. It lists important events that Qian experienced.

D. It is a brief introduction to Qian, a famous Chinese scientist.

2.. Which statement about Qian is TRUE?

A. He was born in China and brought up in America.

B. He went to America for further study after graduation from university.

C. He returned to his hometown right after finishing his education.

D. He had worked on missiles in the US military before coming back to China.

3.Qian was personally involved in many historic events in China EXCEPT .

A. the first spacewalk                                           B. the first man-made satellite

C. the development of missiles                   D. the explosion of an atomic bomb

4. From the article, we can conclude that ________.

A. the US military had hoped to take full advantage of Qian’s talent

B. Qian had an important position in the US military in the 1940s

C. when World War broke out, Qian was studying at Shanghai Jiaotong University

D. it was not easy to get Qian back from the US

America’s greatest technological achievement, the Hoover Dam, now has a companion piece, a bridge held up by the longest arch in the Western Hemisphere（半球）. The Mike O’Callaghan-Pat Tillman Memorial Bridge, which opened this month and connects the U.S. states of Arizona and Nevada, crosses the vast chasm（峡谷）890 feet above the Colorado River that is controlled by the dam.

The striking 1,900-foot-long structure will improve traffic in the region and help protect the dam from being destroyed. It is the seventh highest bridge in the world, behind four in China, one in Papua New Guinea and one in the US state of Colorado.

“The Hoover Dam is the greatest civil engineering achievement in America’s history,” said the bridge project manager Dave Zanatell. “Our goal was not to outdo or outshine it. Our goal was to, in a respectful way, do something that would be great for our generation and that would stand besides Hoover Dam in a respectful and quality way that would become a part of Hoover’s legacy（遗产）.”

Just as the Hoover Dam was built in the heart of the Great Depression（大萧条）and was seen as an example of the nation’s can-do spirit, some hope this project can also provide some uplift.

The bridge is surprising: at 1,050 feet, its support arch holds up a roadway that lies on 300-foot-long concrete pillars（柱子）, some of the tallest in the world. It contains 16 million pounds of steel.

　The idea of the bridge came into being in the 1960s because the top of the Hoover Dam has been a narrow two-lane road that is the fastest route from Arizona to Las Vegas and then the Pacific Northwest and Canada.

　Access to the dam from each direction is a dangerously winding route, but massive trucks and passenger vehicles shared it for decades. During the day, when thousands of tourists travel to the dam from Las Vegas three times as many accidents as on a normal road will happen.

　The bridge has a sidewalk on the side facing the dam. The wall on both sides is 54 inches high, so walkers can take photos there.

1.Which of the following is true of the Hoover Dam?

A. It was completed recently.

B. It was built during the hard times.

C. It has the longest arch.

D. It’s the seventh highest dam in the world.

2.What is one of the purposes of building the bridge?

A. To protect the dam.                                            B. To save the cultures.

C. To outdo the dam.                                                   D. To develop the tourism.

3.The underlined word “uplift” in Paragraph 4 means _____.

A. lift of the heavy object                              B. support in money

C. spiritual encouragement                                   D. instruction in technology

4.Which of the followings shows the right position of the bridge and dam?

5.The text is mainly about ______.

A. the Hoover Dam

B. American western development

C. a tour along the Colorado River

D. a recently built bridge

Breakthroughs in science and technology are paving the way for modern cities to support bigger populations. Now, we see the most exciting urban innovations to show you exactly how they’ll improve your city’s infrastructure(基础设施).

Lighting Up The Night

Anthony Di Mari dreamed up an electric tree to help irrigate public parks and light them at night. These electric trees contain a special infill (填充物) that collects water from rainfall. The water is then distributed through a shallow underground irrigation system with the help from the trees’ swaying movement. An electric motor turns energy from the waving of the artificial trees into electricity, which is used to light up the trees’ outer LEDs.

Thinking Outside The Box

As more people flock to urban areas, city planners will need to get increasingly creative about how to satisfy residents’ health and transportation needs within decreasing available space. One way to achieve this is by updating infrastructure to support biking and walking by building suspended(悬浮的) roundabouts like hovering in the Netherlands. By lifting bicycle and pedestrian traffic above busy roadways, cities can significantly decrease over-crowded traffic condition.

Waving Hello To Clean Energy

Cities that don’t receive enough sunlight may find an attractive alternative in wave power. Since ocean waves rarely experience disruption(中断), electric engines driven by their clockwork push-and-pull can reliably provide power throughout the year. Further, thanks to advances in wave power technology, engineers have been able to move wave power engines farther offshore, where the waves pack the most punch, making the engines extremely efficient. So in the future, heavily populated coastal cities may use wave to meet their energy needs.

1.What is the special infill used to do?

A. To make the trees beautiful.

B. To produce electricity.

C. To help the trees’ swaying.

D. To collect water from rainfall.

2.How do the Netherlands improve the city traffic according to the text?

A. By updating the city roadway condition.

B. By building walking passages underground.

C. By creating suspended roundabouts above roadways.

D. By supporting more biking and walking.

3.What does the author mainly tell us in the last paragraph?

A. The advantages of wave power.

B. The ways to use wave power.

C. The future of wave power.

D. The advances in wave power technology.
