【语篇解读】 本文为说明文。中国已成为第一个在月球背面成功着陆航天器的国家。嫦娥4号探测器的任务是探索月球永不面对地球的一面。它使中国成功地完成了地球上其他国家所没有完成的事情。中国计划将宇航员送上月球并建立自己的空间站。
1．Where did the Chang’e 4 prbe land?
A．On the lunar side facing the earth.
B．On the invisible side f the mn.
C．In a yunger crater n the mn.
D．In a previus space statin.
答案 B [细节理解题。根据第一段中的“The Chang’e－4 prbe (探测器) has als faces the earth.”可知，嫦娥4号探测器的任务是探索月球永不面对地球的一面。“the side f the mn that never faces the earth”即是“the invisible side f the mn”。]
2．Why is the craft equipped with a cntainer?
A．T see what seeds can cme ut n the mn.
B．T cllect sme imprtant matter n the mn.
C．T find whether the seeds can grw n the mn.

答案 C [推理判断题。根据第四段“Chang’e－4 als has t create a miniature (微型的) bisphere”可知，嫦娥4号上还装有矿物检测仪器，以及一个装有种子的容器，试图用这些种子来创造一个微型生物圈。由此可知，用容器里的种子来看看是否能在月球上生长。]
3．What can we learn frm the text?
A．The dark side f the mn is as cld as the ther side.
B．The bright side is yunger and thinner than the ther side.
C．Other places in space may hardly receive signals frm the craft.
D．The tw cameras n the craft can send pictures t the earth easily.
答案 B [细节理解题。根据第一段中的“The dark the visible side.”月球的暗面比能看到的(即亮的)那一面古老、表面要厚些。也就是说亮的那一面比另一面(暗的一面)要年轻些，要薄一些。]
4．Accrding t the text，what will China d in the future?
A．China will land manned space craft n the mn.
B．China will built anther space statin n the mn.

B
Mdern day rbts may nt be as entertaining as R2D2 r the rbt frm Lst in Space，but rbts are very imprtant t space explratin and are being used in a variety f different ways fr several imprtant reasns.
Rbts make great explrers n planets，mns，and ther landing areas.Aside frm the earth，just abut every surface in the slar system is unsafe fr humans t explre.The air n mst ther planets is insufficient fr humans t breathe，making it necessary t wear a space suit and xygen equipment.The temperatures n these surfaces are much t ht r much t cld fr any humans t withstand．Plus there wuld be cmplicatins with radiatin，weather，and a lack f gravity.Rbts have much less limitatin in these areas and can survive much lnger under these cnditins.
Rbts are designed fr cllecting scientific data.Rbts are als able t perfrm many tasks at ne time and can prcess infrmatin much quicker and mre efficiently.Imprtant scientific prjects frm detecting minerals，analyzing grund samples，t finding water are all perfrmed much quicker and accurately by rbts.
The use f rbts has made the cst f space explratin much less expensive than it wuld cst fr humans t d the wrk.In rder t successfully send humans int space we wuld need t build a vehicle that can nt nly carry humans，but als enugh fd and water t keep them alive fr the duratin f the trip.Mrever，rbts have n prblems wrking fr hurs n end.Rbts never cmplain，they dn’t require fd r water，and they never need a bathrm break.
Over the past 30 years r s there have been many different types f rbts used successfully in the explratin f space.Perhaps the mst famus and successful rbts are Spirit and Opprtunity wh have bth been explring the surface f Mars.They have bth been very successful with experiments n sil and rcks and have even fund evidence f water in Mars’ histry.
【语篇解读】 本文是一篇说明文，介绍了机器人对太空探索非常重要，机器人正用于太空探索。

C．N Rbts，N Space Explratin
D．Rbts Are Used in Space Explratin
答案 D [主旨大意题。根据第一段中的“but rbts are very several imprtant reasns.”可知，本文主要介绍了机器人正用于太空探索，故D项正确。]
6．Accrding t the passage，which f the fllwing is NOT true?
A．The use f rbts in space explratin csts mre than the use f humans.
B．It is dangerus fr humans t explre ther surfaces in the slar system except the earth.

7．The underlined wrd “withstand” in paragraph 2 mst prbably means “________”．
A．remainB．bear
C．defeatD．develp
答案 B [词义猜测题。根据画线词所在的句子“The temperatures n these any humans t”可知，温度太高或太低，人类无法忍受，由此可知画线词词义为“忍受”，故选B。]
8．What is the writer’s attitude in this passage?
A．Negative.B．Persuasive.
C．Subjective.D．Objective.
答案 D [观点态度题。纵观全文可知，作者只是客观地介绍了机器人在太空探索中的应用，并没有带任何感情色彩，故选D。]
