【题目】 Americans were shocked to discover that the national bird was in danger of disappearing from the skies forever. Studies in 1970 showed only about 1,000, or fewer, bald eagles(秃鹰) in the country.

The major cause of the problem was people. The spread of civilization(文明) destroyed many of the eagles' feeding and nesting areas. And the eagles were being affected by D-D-T and other insect poisons. The poisons were in the animals the eagles ate. They reduced the eagles' ability(能力) to use calcium(). This made the outside of the eagles' eggs very thin. Often, the eggs broke before baby birds were developed.

In 1972, the U. S. government banned(禁止) D-D-T. People also became interested in protecting places where eagles live. And stronger efforts were made to carry out laws protecting the birds. Scientists began a program that placed baby bald eagles which were born under human care, into nests of wild bald eagles. Often, the wild birds accepted the babies.

These efforts appear to have been successful in saving the American bald eagles. Today the number of the bald eagles has increased to more than 11, 000.

1The main reason of the problem that the bald eagles were in danger is ______.

A. calcium()B. peopleC. the programD. the wild animals

2The wild bald eagles seemed ______.

A. willing to raise the baby eagles hatched(孵出)by man

B. shocked they were in danger of disappearing

C. satisfied with D-D-T and other insect poisons.

D. unwilling to help the scientists to carry out the program

3If no measures had been taken, the bald eagles would ______.

A. have died out in the country

B. have nested(筑巢) in the mountains

C. have broken all their eggs

D. have become wild birds

4Today Americans are no longer ______ the bald eagle.

A. interested in B. disappointed in C. proud of D. anxious about

【题目】 The world's first hydrogen-powered(氢动力) trains have begun running in Germany last month. The new trains will run 100-kilometer trips and can travel up to 140 kilometers an hour.

A French railroad company called Alstom built two hydrogen-powered trains. Teams in Germany and France cooperated on the project, which was supported by the German government. The new train model, called the Coradia iLint, signals the beginning of efforts in Germany and other nations to move away from pollution-producing diesel(柴油) trains.

Compared(相比较) with diesel trains, the Coradia iLint is designed to run on non-electrified train lines with low levels of noise. It uses a process that combines hydrogen and oxygen to produce electrical power. If the system produces more energy than the train needs at that time, it can store the extra energy in batteries. The only emissions(排放物)are water and steam.

A single tank of hydrogen can run a Coradia iLint train for about 1,000 kilometers. This is very similar to the distance a diesel-powered train can run on with a single tank.

Hydrogen-powered trains cost more than diesel trains to build. But Alstom officials say the operating costs are much lower. The company plans to provide another 14 Coradia iLint trains by the year 2021. Several other European countries have also expressed interest in developing hydrogen train systems. France has already said it wants its first hydrogen train to be operated by 2022.

1What's the topic of the passage?

A. A new kind of train

B. Diesel(柴油) trains

C. Water and steam

D. A French railroad company

2Compared with diesel trains, what's the advantage of the Coradia iLint?

A. The Coradia iLint uses electrical power.

B. The Coradia iLint can store the extra energy in batteries.

C. The Coradia iLint is designed to run with low levels of noise.

D. All of the above.

3How many Coradia iLint trains in total will the Alstom have by the year 2021?

A. Two B. Fourteen C. Twelve D. Sixteen

4According to the passage, we can infer that __________.

A. Alstom is the name of hydrogen-powered(氢动力) train.

B. The project was supported by the French government.

C. A diesel-powered train can run about 1,000 kilometers with a single tank.

D. Only one European country has interest in developing hydrogen train systems.

【题目】 In 1996, Subaru Takaiashi sailed alone across the Pacific Ocean. Many other people did this before Subaru, but he was special. At 14, he was the youngest person to sail across the Pacific by himself.

Subaru left Tokyo on 23 July, 1996. His boat was 30 feet (9 metres) long. In the boat, he had a two-month supply of food and water. He also had a radio and other modern equipment for sailing.

The beginning of this trip went very well. Subaru often talked to his parents by radio. He didn't have any problems with his boat. Then on 11 August, the engine in his boat quit.
