During the years after the terrorist attack on the World Trade Center, structural engineers have been trying hard to solve a question that would otherwise have been completely unthinkable: Can building be designed to stand catastrophic blasts (攻击；爆破) by terrorists?

Soon after the terrorist attacks on the twin towers, structural engineers from the University at Buffalo and the Multidisciplinary Center for Earthquake Engineering Research (MCEER) traveled to ground zero as part of a project funded by the National Science Foundation. They spent two days beginning the task of formulating (构思) ideas about how to design such structures and to search for clues on how to do so in buildings that were damaged, but still are standing.

“Our objective in visiting ground zero was to go and look at the buildings surrounding the World Trade Center, those buildings that are still standing, but that sustained damage,” said Mr. Bruneau, Ph.D. “Our immediate hope is that we can develop a better understanding as to why those buildings remain standing, while our long-term goal is to see whether earthquake engineering technologies can be married to existing technologies to achieve enhanced performance of buildings in the event of terrorist attacks,” he added.

Photographs taken by the investigators demonstrate the monumental damage to the World Trade Center towers and buildings nearby. One building a block away from the towers remains standing, but was badly damaged. “This building is many meters away from the World Trade Center and yet we see a column (柱子) there that used to be part of that building,” explained A. Whittaker, Ph.D. “The column became a missile that shot across the road, through the window and through the floor.”

The visit to the area also brought some surprises, according to the engineers. For example, the floor framing (框架) system in one of the buildings was quite strong , allowing floors that were pierced by tons of falling debris (残砾) to survive. “Good framing systems may provide a simple, but reliable strategy for blast resistance,” he added. Other strategies may include providing alternate paths for gravity loads in the event that a load-bearing column fails. “We also need a better understanding of the mechanism of collapse,” said A. Whittaker. “We need to find out what causes a building to collapse and how you can predict it.”

A. Reinhorn, Ph.D. noted that “earthquake shaking has led to the collapse of buildings in the past. Solutions developed for earthquake-resistant design may apply to blast engineering and terrorist-resistant design. Part of our mission now is to transfer these solutions and to develop new ones where none exist at present.”

1.The question raised in the first paragraph is one _____ .

A. that was asked by structural engineers a month ago

B. that is too difficult for structural engineers a month ago

C. that was never thought of before the terrorist attack

D. that terrorists are eager to find a solution to

2.The column mentioned by Dr. Whittaker _____ .

A. was part of the building close to the World Trade Center

B. was part of the World Trade Center

C. was shot through the window and the floor of the World Trade Center

D. damaged many buildings near the World Trade Center

3.A surprising discovery made by the investigators during their visit to ground zero is that _____.

A. floors in the faraway buildings remained undamaged

B. some floor framing systems demonstrate resistance to explosion

C. complex floor framing systems are more blast resistant

D. floors in one of the buildings were pierced by tons of debris

4. What Dr. Reinhorn said in the last paragraph may imply all the following EXCEPT that _____.

A. blast engineers should develop new solutions for terror-resistant design

B. blast engineering can borrow technologies developed for terror-resistant design

C. solutions developed for earthquake-resistant design may apply to terrorist-resistant design

D. blast engineering emerges as a totally new branch of science

After the September 11 terrorist attacks, some high schools in America wanted the students to pledge allegiance（宣誓效忠） to the flag. Is it necessary or not? Let’s see how the kids think of this requirement.

Lea Mouallem, Marymount High School

I believe that saying the Pledge of Allegiance is a way of reminding our country that no matter what happens, we are united. I don’t think our president wants us to go and join the army now, but he wants to tell us that we will be able to overcome the disaster as a whole nation that is working together.

Harry Chin, 15, Culver City High School

I am not for the Pledge of Allegiance and I am not against the Pledge of Allegiance because I just say it so many times that it loses meaning. I say it every day at school in the second period. It doesn’t mean anything any more.

David Tran, 15, Warren High School.

The Pledge of Allegiance is another sign of country. We should have some respect to it. In many schools, we don’t say the Pledge every morning-we just stand up and let the National anthem ring through the silence. We said the Pledge of Allegiance on Sept. 12.

Danny Maryanor, 16, Santa Monica High School

I wonder why we were suddenly asked to recite the Pledge when many of us stopped after elementary school; and the Pledge was recited before the play of “Ode to Joy” （欢乐颂）with recorders. This was not to express patriotism（爱国主义）, or even to remember those who lost their lives on Sept. 11.

I feel I cannot support a nation that in this time of crisis looks outward for revenge（报复）instead of inward for peace. Perhaps we should think more about our problems.

1．Saying the Pledge of Allegiance to the flag first appeared in American schools_______.

A．after Sept. 11, 2000  B．before Sept. 11, 2001

C．on Sept. 11, 2001                D．after Sept. 11, 2001

2．Who were for the Pledge of Allegiance?

A．Lea Mouallem; David Tran         B．Harry Chin; Danny Maryanor

C．Lea Mouallem; Danny Maryanor       D．Harry Chin; David Tran

3．Which of the following is TRUE?

A．Harry Chin thought the government required them to join the army.

B．Lea Mouallem thought the Pledge of Allegiance of no meaning.

C．Danny Maryanor felt the terrorist attacks happened partly because of America’s own problem.

D．The Pledge of Allegiance is of another country.

4．According to the passage, it can be imagined that___________.

A．all high school students say yes to the Pledge of Allegiance.

B．all high school students say no to the Pledge of Allegiance.

C．all kids don’t agree to the requirement of saying the Pledge of Allegiance.

D．all high schools will require their students to pledge allegiance to the flag.

Thousands of people in the world are a hundred years old － or more and certain parts of the world are famous for the long lives of their inhabitants: the Vilacamba Valley in Ecuador, and the home of the Hunzas in the Himalayas.

Why do so many people live to a healthy old age in certain parts of the world? What is the secret of their long lives? Three things seem to be very important: fresh air, fresh food and a simple way of life. People work near their homes in the clean mountain air instead of traveling long distances to work by bus, car or train. They do not sit all day in busy offices or factories, but work hard outdoors in the fields. They take more exercise and eat less food than people in the cities of the West. For years the Hunzas of the Himalayas did not need policemen, lawyers or doctors. There was no crime, no divorce and not much illness in their society. They were a happy, peaceful people, famous all over India for their long, healthy lives.

Do you want to live to a hundred years old? Here are some rules for success. First, live in the right place. Second, choose the right kind of job. Doctors, dentists and bus－drivers die young. Farmers, priests and orchestral conductors live much longer. If you are in the wrong kind of job, you can still improve your way of life.

An old man in the Caucasus was talking about his past life. “I was young then，” he said, as he described his 87th year. His secret was: “Think young and stay young.” An old woman from Missouri, the USA, gave this advice, “Drink a little whisky and some warm beer every day.” An English lady just said, “Take a cold bath every morning.” The shortest, simplest piece of advice came from Mr Jim Chapman, aged 103. “Just keep breathing，” he told reporters.

1.Who is most likely to live a long life?

2.We can see from the passage that long－lived people avoid ______.

3. The passage indicates that we can change our ______ to live a long life.

4.What is mainly talked about in the last paragraph?

Today, people all over the world are moving out of small villages in the country to go and live in big, noisy cities. They are moving from the peaceful hills, mountains, fields, rivers and streams of the countryside to the busy world of streets, buildings, traffic and crowds. This movement from rural areas to urban areas has been going on for over two hundred years.

In many countries, the main reason people come to live in towns and cities is work. After one or two large factories have been built in or near a town, people come to find work, and soon an industrial area begins to grow. There is usually a residential area nearby, too. The families of these workers need schools, hospitals and shops, so many people come to live in the area to provide these services and a city grows.

In every major city in the world, there is a business district where the big companies have their main offices. In the United States, this area is usually in the city center downtown. It is here that you can see many huge skyscrapers(摩天大楼) and office blocks. The people who work here often travel a long way to work each day. Many of them live in the suburbs of the city, far away from the industrial area and the city center. Some suburbs are very pleasant, with nice houses and big gardens. There are usually parks for children to play in and large department stores where you can buy all you need.

But what is the future of the big cities? Will they continue to get bigger and bigger? Perhaps not. Some major cities have actually become smaller in the last ten years, and it is quite possible that one day we will see people moving out of the major cities and back into smaller towns and villages.

1.Why do people move to live in cities or towns?

A．Because they can live more comfortably there.

B．Because they like noisy life better than peaceful life.

C．Because they mainly want to find work there.

D．Because they are sure of having a better life there.

2.The underlined phrase “a residential area” means an area________.

A．where people can buy things

B．which is suitable for living in

C．where people can do business

D．which is near a city center

3.Which of the following statement is NOT true about the business district?

A．Big companies usually have their main offices in the business district.
