题目内容

After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: The damage and death toll(死亡人数)could have been much worse.

More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity(强度)that shook America in 1988 claimed 25, 000 victims.

Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4：31 a．m. on a holiday, when traffic was light on the city's highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes(抗震)．

Despite the good news, civil engineers aren't resting on their successes. Pinned to their drawing boards are blueprints(蓝图)for improved quake－resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place.

In the past, making structures quake－resistant meant firm yet flexible materials, such as steel and wood, which bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports. Called smart buildings, the structures respond like living organisms to an earthquake's vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction.

The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

6．One reason why the loss of lives in the Log Angeles earthquake was comparatively low is that______.

A．new computers had been installed in the buildings

B．it occurred in the residential areas rather than on the highways

C．large numbers of Los Angeles residents had gone for a holiday

D．improvements had been made in the construction of buildings and highways

7．The function of the computer mentioned in the passage is to______.

A. counterbalance(起平衡作用)an earthquake's action on the building

B. predict(预测)the coming of an earthquake with accuracy

C. help strengthen the foundation of the building

D. measure the impact of an earthquake's vibrations

8．The smart buildings discussed in the passage________.

A. would cause serious financial problems

B. would be worthwhile though expensive

C. would reduce the complexity of architectural design

D. can reduce the ground vibrations caused by earthquakes

9．It can be inferred from the passage that in minimizing(使……最小)the damage caused by earthquakes, attention should be focused on________.

A．the increasing use of rubber and steel in capital construction

B．the development of flexible building materials

C．the reduction of the impact of ground vibrations

D．early forecasts of earthquakes

10．The author's main purpose in writing the passage is to________.

A．compare the consequences of the earthquakes that occurred in the US

B．encourage civil engineers to make more extensive use of computers

C．outline the history of the development of quake－resistant building materials

D．report new developments in constructing quake－resistant buildings

For centuries,the only form of written correspondence (通信)was the letters, letters were, and are, sent by some form of postal service, the history of which goes back a long way .Indeed, the Egyptians began sending letters from about 2000 BC,as did the Chinese a thousand years later.

Li Lu’ou thought he did the right thing by calling 110 when he saw his two classmates in trouble on the corner of a dark street.

Li and his classmates from NO.2 Middle School Affiliated to Beijing Normal University spent this year’s Valentine’s Day selling roses on the street.As night approached，they cycled back with over 200 yuan in their pockets.

Suddenly，a gang of robbers jumped out at them.The five robbers were tall and strong，so Li ran away to call the police.He thought it would be the most practical thing to do and he was right.His classmates returned safe and sound.

So，what would you have done in Li’s situation？Would you have got off your bike and fought the robbers to rescue your friends?

A new Beijing student code does not encourage you to risk your life to help them.

The new code was introduced to more than 1.7 million primary and middle school students in the city at the start of the new term.

It has cut words which might encourage youngsters to risk their lives for others dangerous situations.Gone are the old calls，which had been in place since 1987，for students to“fight criminals courageously”and “sacrifice themselves to save others”．

Children’s heroic acts usually left them injured or even dead because they failed to fully foresee the dangers of their actions.

A wellknown example was Lai Ning，who was listed among the “top 10 model young pioneers” in 1989 after he lost his life trying to put out a fire at the age of 14.

The deaths connected to teenagers’“heroic acts” started a nationwide debate about the protection of youngsters.

Wei Lusheng，a parent in Beijing，said schools must first teach children how to protect themselves，before learning from heroes.

But educators thought the spirit of courage should not be thrown away in the new student code.

“Getting rid of the words‘fight criminals courageously’do not mean we deny the spirit of‘fearlessness’and ‘readiness’to help others.”said Li Jing，an official in Beijing.“But，we should be more rational about the spirit of sacrifice.”

Li Lu’ou agreed.“Cherishing life is no reason to be a coward，” he said.“but you need make sure you are able to offer help.For example，it would cause more trouble if I jumped into water to rescue someone drowning，but didn’t know how to swim.In that situation it’s better to call the police or an adult.”

41．Which is true about Li and his classmates?

A．They bought roses for each other on Valentine’s Day.

B．They called 110 immediately when they were held up by a gang of robbers.

C．Li risked his life for his classmates in the dangerous situation.

D．Instead of fighting the robbers Li thought it right for him to call the police.

42．The new student code was introduced in Beijing because______.

A．students are facing more danger than they used to

B．the old student code didn’t include the spirit of courage

C．the old one didn’t tell students how to protect themselves while helping others in trouble

D．the old student code encouraged students to sacrifice themselves to save others.
