China will soon put a person into space and become the third nation in the world to have manned spaceflight, a tap Chinese aerospace(航空航天)official said on November 5.
A manned launch(发射) was not far off, Vice President Hu Hongfu of China Aerospace Science Technology Corp(CASTC)told a news conference at the third Zhuhai Air Show.“It will not be long before Chinese astronauts can ride locally - made spaceships into space,”Hu said. The official gave no timetable but said it would happen“at beginning of the 21st century.”
The former Soviet Union and the United States have been putting people into orbit since the early 1960s, but other nations have not considered the challenge worth following.
China has already built and sent up its own satellites for communications and weather forecasting. The new communication satellites would help to encourage the country's broadcasting industry, Hu said.
But the company, which includes over 130 aerospace agencies, said the lifting ability and success rate of China's space - launches were almost equal in quality to those of other countries.
China would gradually close the distance between its country's space industry and that of other nations. He added that they were willing to send up commercial satellites for Taiwan.
On China's plan to end up manned spaceflights, Hu said China had made important development after the successful launch in November last year of the country's first experimental spaceship, Shenzhou. “The whole project is in the research stage and a lot of work needs to be done,”Hu said.“We need to have more tests of the unmanned spaceship.”
China last year announced a four-step manned spaceflight plan with the aim of setting up a spacestation served by a spaceship travelling between two places.

In the 1940s, Pinehaven Park was one of Crafton City's loveliest recreation(娱乐)areas. Over 40 acres of woods and fields were open to the public. In the 1950s, part of the park was taken over by Crafton City's garbage. Fifteen acres were to be used for landfill disposal(理置). As time went on, more and more of the park was used for garage disposal and less for recreation. Two years ago, the park was closed to the public for good. Along with household garbage, industrial chemicals had for years been dumped (倾倒)in the Pinehaven landfill. These poisonous chemicals had begun to seep(渗)back up through the soil. All of Pinehaven Park had become dangerously polluted.
Last year, the fish in the Crafton River began to die. After a series of investigations(研究), it became clear that the people of Crafton City were not to blame. 100～150 miles upstream, big paper mills were dumping industrial wastes into the river. Little by little, the level of poison in the river began to rise. Finally, it became so polluted that the fish themselves could no longer survive.
Downtown Crafton used to be a quiet area. Ten years of remarkable growth changed that in a big hurry. But with Crafton City's new prosperity(繁荣)came a new problem: air pollution. And it is a serious problem. Air pollution levels in Crafton are regularly reaching those of the nation's large industrial cities.
(1)Which of the following best states the central idea of the passage?
[ ]
A．Chemical dumping is a serious threat to Crafton City's soil.
B．The rapid growth of industry has brought air pollution to Crafton City.
C．The disposal of garbage can destroy recreation areas.
D．Industrial growth and progress have resulted in the pollution of Crafton City's water, air, and soil.
(2)According to the passage, what portion of the park had originally been marked for use as a garbage dump?
[ ]
A．Less than half B．Exactly half
C．About one third D．Most of it
(3)As it is used in the passage, the phrase“for good”means ________.
[ ]
A．practically B．for ever
C．thoroughly D．advantageously
(4)According to the passage, one result of dumping industrial chemicals into the landfill was that ________.
[ ]
A．the land became unsafe for humans
B．the animals on the land died
C．the poisonous chemicals were washed into the nearby river
D．the smoke from the chemicals polluted the air surrounding the landfill
