Question

Beijing—（13, July） China sent up a new data relay satellite（數(shù)據(jù)中繼衛(wèi)星）, Tianlian I-02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan province．The new satellite will promote the country's satellite communication network for space docking（對接）．

The satellite was launched on a Long-March-3C carrier rocket at 11:41 p．m．, sources at the centre told Xinhua News Agency．The satellite separated from the rocket 26 minutes after its launch and was then successfully delivered into a geostationary transfer orbit （地球同步轉(zhuǎn)移軌道）．

Developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the satellite is the country's second data relay satellite．The first, Tianlian I-01, was launched on April 25．2008．

The two satellites will form a network to improve communications between China's spacecraft and bases on Earth, according to the centre．They will also be used to help the nation's first space docking, scheduled for the second half of this year．

As planned, China will launch space module Tiangong-I, which was designed as a platform that will dock with an unmanned spaceship, Shenzhou, for the county's first space-docking mission this year．

Two more Shenzhou spaceships will dock with Tiangong-I next year, and one will be manned by two or three astronauts, according to China Manned Space Engineering Office, which was the main user of the Tianlian I series data relay satellites．

“The new satellite can cover a greater area to track and command the country’s space vehicles in low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position in outer space．Only three satellites of this kind are needed to form a global communication network, and China has two now．” Pang Zhihao, a researcher and deputy editor-in-chief of Space International, said．

The satellite could also equip astronauts with real-time communications, which will benefit the country's future manned space flights, he said．

1.What is the main purpose to send up Tianlian I-02 ?

A．To test the function of a Long-March-SC carrier rocket．

B．To carry some astronauts into space to do some research．

C．To send more information and clearer pictures to mobile phones on the earth．

D．To promote the country's satellite communication network for space docking．

2.From the passage we know??????????? ．

A．one more such satellite is needed to form a global communication network

B．the satellite was developed by China Manned Space Engineering Office

C．it was less than three years since China launched its first date relay satellite of this kind

D．the satellite could help track and command space vehicles in orbits because it's lower in position

3.Which of the following is TRUE according to the news report?

A．Shenzhou Ⅷ is a manned spaceship．

B．Tiangong-I will dock with three Shenzhou spaceships next year．

C．the satellite is of great importance to China's space exploration．

D．china’s first space docking will be done in the second half of next year．

4.The best title of the passage could be___________．

A．China Launched a New Space Shuttle

B．China's Plan for Space Exploration

C．China’s Progress in China's Space Exploration

D．New Satellite Helps China's Space Exploration

【解析】

試題分析：本文主要講述的是我國發(fā)射了數(shù)據(jù)中繼衛(wèi)星 Tianlian I-02,分析了這顆衛(wèi)星對中國太空探索的重要性和價值。

1.D 細節(jié)題。根據(jù)第一段最后一句The new satellite will promote the country's satellite communication network for space docking（對接）．可知發(fā)射這棵衛(wèi)星的目的在不促進衛(wèi)星的通訊網(wǎng)絡(luò)的對接。故D項正確。

2.A 推理題。根據(jù)倒數(shù)第二段最后3行Only three satellites of this kind are needed to form a global communication network, and China has two now．” Pang Zhihao, a researcher and deputy editor-in-chief of Space International, said．可知需要三顆衛(wèi)星才可以形成一個全球的衛(wèi)星交流的網(wǎng)絡(luò)，中國現(xiàn)在已經(jīng)有了2顆，那么我們還需要一顆就可以了。故A正確。

3.C 推理題。根據(jù)倒數(shù)第二段1,2行The new satellite can cover a greater area to track and command the country’s space vehicles in low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position in outer space．可知這顆衛(wèi)星對太空探索是非常重要的。故C項正確。

4.D 主旨大意題。根據(jù)文章第一段可知本文主要講述的是中國所發(fā)射的一顆新的衛(wèi)星對太空探索的重要性。故D項正確。
