解析:

1. D  此句中指出的是:中國人該找到的空間。顯然用room, 而不是其它實物體名詞。

2. B  journey和trip只作名詞,travel和tour既可作名詞,又可作動詞; travel正式的通常概念上的旅行,最后一定要返回出發(fā)地;tour側(cè)重到多處觀光,強調(diào)路線曲折。

3. A  根據(jù)句意,中國人是首次登北極,故用first。

4. C  選項A、 B和D不合句意;announce多強調(diào)宣布公眾所關(guān)心的社會問題。

5. D  短語a while ago方才, 剛才。

6. C  hold back阻止, 抑制; 其它搭配均不合句意。

7. A  which引導(dǎo)非限制性定語從句,關(guān)系代詞which在從句中作主語。

8. A  根據(jù)句意,此處該用介詞during。其它為連詞,不合句意。

9. B  作幾個常用詞的用法比較:rise(太陽、水、氣等的)升起;raise(人為的)升起;lift舉起;carry攜帶。

10. C  眾所周知的時刻,known as polar day作定語,修飾a time。

11. A  版圖與擴展之間存有主謂關(guān)系,故用spreading。

12. D  work out設(shè)計出, 做出;pick out 挑選; keep out 使在外; carry out貫徹, 執(zhí)行。本句句意為:中國在實施著許多研究,目的是想了解更多的北方氣候和環(huán)境的變化。故選D。

13. B  根據(jù)第12題句意,可知。

14. B  such as表示列舉, for example = for instance舉例說明,such that如此。

15. A  have something to do with 與......有關(guān)。

16. C  選項A、D不合句意;B為不及物動詞;故選C。

17. C  in greater depth意為在更深層處,greater強調(diào)與此之前的含蓄比較。

18. A  include強調(diào)包含有,而contain表示內(nèi)容,不用進(jìn)行時,including為介詞。

19. D  of與抽象名詞連用相當(dāng)于該名詞的形容詞,即of great support = very supportable。

20. C  為which was established的省略形式

Except for the sun, the moon looks like the biggest object in the sky. Actually it is one of the smallest, and only looks big because it is so near to us. Its diameter(直徑) is only 2,160 miles (3,339 km) ,or a little more than a quarter of the diameter of the earth.

Once a month, or more exactly, once every 29.5 days, at the time we call “full moon”, its whole disc looks bright. At other times only part of it appears bright, and we always find that this is the part which faces towards the sun, while the part racing away from the sun appears dark. People could make their pictures better if they kept this in mind — only those parts of the moon which are lighted up by the sun are brighter. This shows that the moon gives no light of its own. It only throws back the light of the sun, like a huge mirror hung in the sky.

Yet the dark part of the moon’s surface is not completely black; usually it is just light enough for us to be able to see its shape, so that we speak of seeing “the old moon in the new moon’s arms”. The light by which we see the old moon does not come from the sun, but from the earth. We know well how the surface of the sea or of snow, or even of a wet road, may throw back uncomfortably much of the sun’s light on to our faces. In the same way the surface of the whole earth throws back enough of the sun’s light on to the face of the moon for us to be able to see the parts of it which would otherwise be dark.

72. Why is the dark part of the moon not completely black?

A. The sun shines on the moon’s surface.

B. The earth throws back sunlight on to the moon.

C. The moon throws back the light from the sun.

D. The moon has light of its own.

73. The underlined word “disc” in the second paragraph refers to _______.

A. a round plate                                 B. a round record

C. the moon that reflects sunlight         D. the moon which looks like a round plate

74. By saying “the old moon in the new moon’s arms” , we mean a time when ______.

A. the two moons are closely linked

B. the new moon is at its brightest

C. the moon is partly bright and partly dark

D. the new moon is hugging the old moon

75. Which of the following is true according to the text?

A. The moon which appears round at its brightest is called full moon.

B. The moon’s diameter is exactly one fourth of that of the earth.

C. The light by which we see the old moon comes from the sun

D. The part of the moon which is not lighted by the sun is completely dark.
