Question

【題目】 China will follow up on its successful mission (任務(wù)) to the far side of the moon by sending a probe to Mars next year, one of its top space scientists said Sunday. Wu Weiren, chief designer of China’s lunar exploration program, said the red planet was the natural next step. “Next year we’ll launch a Mars probe to orbit around the Mars, land on it and probe it,” he said. China will also send another probe to take back samples from the moon’s surface.

Wu’s comments came as a Mars simulation(模擬) base opened in Qinghai’s Qaidam Basin. According to the state-run Global Times, while the red rocky area bears a strikingly similarity to Mars, it’s extremely difficult to simulate Mars due to its special natural features and hostile environment—low air pressure, strong radiation and frequent sandstorms, as well as vast differences in geography.

China didn’t send its first satellite into orbit until 1970, by which time America had already landed an astronaut on the moon, but it’s been catching up fast. Since 2003, China has sent six crews into space and two space labs into Earth’s orbit In 2013, China successfully landed a rover, Yutu 1, on the moon, becoming only the third country to do so.

Last December, China landed another probe and a rover, Yutu 2, on the far side of the moon. Progress has been slow going since then: due to the extreme conditions there, the rover often has to hibernate to preserve its capabilities for further exploration, Wu said. “The temperature there is minus 190 degrees Celsius, which all components and parts cannot stand. So we let it sleep for a while, making sure it can spend the night safely. A few days ago, it woke up automatically to work. We’ve gained lots of data in the past few days, and we're going to make the data known to the world,” Wu said.

【1】What’s China’s next step in its space exploration?

A.To get back a probe from Mars.

C.To land a rover on Mars successfully.

D.To open a Mars simulation base.

【2】Which does the underlined word “hostile” in Paragraph 2 probably mean?

A.Stable.B.Uncertain.

C.Unfavorable.D.Friendly.

【3】What can be learned from the last paragraph?

A.Yutu 2 often has to hibernate to save its energy.

B.The data from Yutu 2 is accessible to the world.

C.Progress has been steady in the past exploration.

D.Yutu 2 can survive the moon's extreme conditions.

【4】Which of the following has China achieved in exploring space?

A.Two space labs have been set up.

B.Six crews were sent into space in 2003.

C.Samples from the moon have been taken back.

D.China became the third to send a satellite to Earth’s orbit.

Answer 1

【答案】

【1】B

【2】C

【3】D

【4】A

【解析】

這是一篇說明文。文章主要說明了主要介紹了中國太空探索的發(fā)展及成就。

【1】細節(jié)理解題。根據(jù)第一段第一句China will follow up on its successful mission to the far side of the moon by sending a probe to Mars next year, one of its top space scientists said Sunday.（周日，中國一位頂級太空科學(xué)家表示，中國將繼續(xù)其成功的月球背面探測任務(wù)，于明年向火星發(fā)射探測器。）可知中國太空探索的下一步是明年探測火星。故選B。

【2】詞義猜測題。根據(jù)下文low air pressure, strong radiation and frequent sandstorms, as well as vast differences in geography.為列舉火星上的不利環(huán)境，如低氣壓、強輻射和頻繁的沙塵暴，以及巨大的地理差異等。故可推測劃線單詞意思為“不宜的；不利的”，故選C。

【3】推理判斷題。根據(jù)最后一段中Progress has been slow going since then: due to the extreme conditions there, the rover often has to hibernate to preserve its capabilities for further exploration, 以及A few days ago, it woke up automatically to work. We’ve gained lots of data in the past few days, and we're going to make the data known to the world（幾天前，它自動醒來工作。在過去的幾天里，我們獲得了大量的數(shù)據(jù)，我們將把這些數(shù)據(jù)公之于眾。）可知“玉兔2號”可以在月球的極端條件下生存。故選D。

【4】細節(jié)理解題。根據(jù)第三段Since 2003, China has sent six crews into space and two space labs into Earth’s orbit（自2003年以來，中國已經(jīng)將6名宇航員送入太空，并將兩個太空實驗室送入地球軌道。）可知中國在探索太空方面已經(jīng)建立了兩個太空實驗室。故選A。
