A new chapter opened in mankind's exploration of the moon on Thursday morning as the first probe(航天探测器) to land on the moon's far side reached its destination after a 26day journey. The Chang'e 4 lunar probe，representing China's latest step in lunar investigation，landed at 10：26 am at the Von Kármán crater and then sent back three photos of the landing site shot by cameras on the probe's lander(着陆器)，marking the world's first images taken on the surface of the far side.
One of the photos，published by the China National Space Administration，shows the place where Chang'e 4's rover，which was named Yutu 2 on Thursday night，will be heading to explore and survey. Thus began the first long journey to the side of the moon that faces away from the Earth.It is meant to fulfill scientists' longheld desire to closely observe the lesser known region.
Tidal(潮汐的) forces on Earth slow the moon's rotation to the point that the same side always faces Earth.The other side，most of which is never visible from Earth，is the far side of the moon.While it has been photographed by spacecraft，starting with a Soviet probe in 1959，no probe had ever made a soft landing there，so scientists had not been able to conduct surfacelevel observations and surveys of the region.
Wu Weiren，chief designer of China's lunar program，said in Beijing on Thursday that the landing“was perfect”．He called the event“an important milestone for China's space exploration”，adding that it has made a good start for future lunar exploration efforts.
With its investigation of the far side，particularly the Von Kármán crater，the Chang'e 4 mission will enable scientists to find out what they haven't known about the moon and deepen their knowledge of its early history and of the solar system.
【语篇解读】 嫦娥四号探测器在月球背面着陆，这标志着中国探月工程的巨大进步，同时也为人类了解月球的背面提供了信息。
1．What is the first paragraph mainly about?
A．The basic data of the Chang'e 4 lunar probe.
B．The Chang'e 4's worldfirst landing on the moon's far side.
C．The Chang'e 4's 26day visit to the far side of the moon.
D．The description of the photos taken on the surface of the moon's far side.
B [考查主旨大意。根据第一段第一句“A new chapter opened in mankind's exploration of the moon on Thursday morning as the first probe(航天探测器) to land on the moon's far side reached its destination after a 26day journey”可知，本段主要介绍了嫦娥四号实现了人类首次在月球背面着陆。故选B。]
2．What does the underlined word“it”in the third paragraph refer to?
A．The lander.
B．The rover.
C．The far side of the moon.
D．The Chang'e 4 lunar probe.
C [考查词义猜测。根据第三段的第二句“The other side，most of which is never visible from Earth，is the far side of the moon”以及画线词所在句中的“While it has been photographed by spacecraft”可知，it在这里指代“the far side of the moon”，故选C。]
3．What can we infer from this text?
A．It is only on the moon that people can explore the deep space.
B．The scientific information obtained by Chang'e 4 will be new to the world.
C．It is the first time for people to see the pictures of the far side of the moon.
D．Chinese space technology is more advanced than that of any other country's.
B [考查推理判断。根据第一段最后一句中的“marking the world's first images taken on the surface of the far side”可知，嫦娥四号月球探测器发回的照片是世界上首次在月球背面拍摄照片，由此可推知，B项正确。]
4．In which section of a website can we probably read this text?
A．Tourism.
B．Health Care.
C．Science and Technology.
D．Art and Entertainment.
C [考查文章出处。本文为新闻报道，介绍了嫦娥四号探测器首次在月球背面着陆，这标志着中国探月工程的巨大进步，由此可推知，本文可能出自一个网站的科技版面。故选C。]
