China has launched a mission to try to get rock samples from the Moon. Its robotic Chang'e-5 spacecraft departed the Wenchang launch complex on a Long March 5 rocket early on Tuesday morning local time, and if successful should return to Earth in mid-December. It's more than 40 years since the Americans and the Soviets brought home lunar rock and "soil" for analysis. China aims to be only the third country to achieve this feat, which will be an extremely complex endeavour.

It's a multi-step process that involves an orbiter, a lander-ascender and finally a return component that uses a capsule to survive a fast and hot entry into Earth's atmosphere at the end of the mission. But confidence should be high after a series of lunar missions that started just over a decade ago with a couple satellites. These were followed up by lander-rover combinations—with the most recent, Chang'e-4, making a soft touch down on the Moon's farside, something no nation had previously accomplished.

Chang'e-5 is going to target a nearside location called Mons Rümker, a high volcanic complex in a region known as Oceanus Procellarum. The rocks in this location are thought to be very young compared with those sampled by the US Apollo astronauts and the Soviet Luna robots. This will give scientists another data point for the method they use to age events in the inner Solar System.

When Chang'e-5 arrives at the Moon, it will go into orbit. A lander will then detach and make a powered descent. Once down, instruments will characterise the surroundings before getting some surface material. The lander has the capacity also to drill into the soil. An ascent vehicle will carry the samples back up to rendezvous with the orbiter. A shepherding craft will direct the capsule to enter the atmosphere over Inner Mongolia.

1.The underlined word “feat” in the first paragraph refers to ______.

A getting rock samples from the Moon

B building the Wenchang launch complex

C going beyond the Americans and the Soviets

D taking amounts of the soil from the Sun

解析：选A。推理判断题。根据文章第一段第二段后半部分的the Americans and the Soviets brought home lunar rock and "soil" for analysis可以得知这个feat就是把月球上的岩石带回地球来研究，故选A。

2.What did the spacecraft use to bear the hot air when returning to the Earth?

A The lander.

B The capsule.

C The shepherding craft.

D The flying satellite.

解析：选B。细节理解题。根据文章第二段第一句finally a return component that uses a capsule to survive a fast and hot entry into Earth's atmosphere at the end of the mission可以得知在返回地球的时候为了预防过热的空气，科研人员用太空舱来保护航天器，故选B。

3.What is the importance for Chang'e-5 to get rocks in Mons Rümker?

A It will confirm the Moon is a high volcanic complex.

B It will help know the exact age of the inner Solar System.

C It will prove the US Apollo astronauts are actually right.

D It will show the Soviet Luna robots are better than China’s.

解析：选B。推理判断题。根据文章第三段最后一句This will give scientists another data point for the method they use to age events in the inner Solar System可以得知嫦娥五号获得的岩石样本能更准确太阳系内部的年龄，故选B。

4.What will Chang'e-5 do before getting the samples?

A It will go back to the earth orbit.

B It will drill deep into the hard soil.

C It will make clear of surroundings.

D It will analyse the soil of the moon.

解析：选C。推理判断题。根据文章最后一段段第二句Once down, instruments will characterise the surroundings before getting some surface material可以得知在开始挖掘样本之前，那些工具要弄清周围的环境，故选C。
