What is a black hole? Well, it is difficult to answer the question,

as the terms we would normally use to describe a scientific phenomenon __1__

are adequate here. Astronomers and scientists think that a black hole is __2__

a region of space which matter has fallen and from which nothing can __3__

escape—not even light. But we can’t see a black hole. A black hole __4__

exerts a strong gravitational pull and yet it has no matter. It is only

space—or thus we think. How can this happen? __5__

The theory is that some stars explode when their density increases

to a particular point; they “collapse” and sometimes a supernova occurs.

The collapse of a star may produce a “White Dwarf” of a “neutronstar”—

a star which matter is so dense that if continually shrinks by the force of __6___

its own gravity. But if the star is very large, this process of shrinking may

be so intense that a black hole results in. Imagine the earth reduced to the __7__

size of a marble, but still having the same masses and a stronger __8__

gravitational pull, and you have some ideas of the force of a black hole. __9__

And no matter near the black hole is sucked in. __10__

答案:

1 將as 改為since或者because。在表示原因的連接詞中,只有as引導(dǎo)的原因狀語從句不能位于主句之后,只能位于句首。

2 將adequate 改為inadequate,或者在are后加not。從邏輯上分析,因?yàn)槲覀儞碛械目茖W(xué)術(shù)語“不充足”,所以才無法回答這個(gè)問題,所以用否定形式。

3 在which 前加into。這是一個(gè)定語從句,意思是“黑洞是太空中物質(zhì)可以掉進(jìn)去的地方”,所以定語從句應(yīng)該為“into which matter has fallen”。

4 將but 改為 so。 上文已提到“連光都無法從黑洞中逃出”,所以我們根本無法看到黑洞。這里應(yīng)該是因果關(guān)系,而不是轉(zhuǎn)折關(guān)系。

5 將thus改為so。這句話的意思是“那只是空間—或者我們認(rèn)為它只是空間”。so做 think 的賓語,thus 只能做連詞,不能做賓語。

6 將which 改為whose。這個(gè)定語從句的意思是“它是一顆星,其密度非常大,由于自身的引力,它在不斷地收縮”。matter 屬于star,所以關(guān)系代詞應(yīng)該用whose。

7 去掉in。result為不及物動詞,意為“形成了”,而“result in sth?!币鉃椤皩?dǎo)致某結(jié)果”。

8 將masses 改為mass。mass 可指“大量的物質(zhì)”,而“the masses”特指“勞動群眾”,用在此處不妥。

9 將ideas 改為idea?!癷dea”在表達(dá)“印象”時(shí),為不可數(shù)名詞,不可以用復(fù)數(shù)。

10 將no改為any。分析便知,任何在黑洞附近的東西都會被吸進(jìn)去。
