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

          改錯模擬試題含答案

            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,因為我們擁有的科學術語“不充足”,所以才無法回答這個問題,所以用否定形式。

            3 在which 前加into。這是一個定語從句,意思是“黑洞是太空中物質可以掉進去的地方”,所以定語從句應該為“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。這里應該是因果關系,而不是轉折關系。

            5 將thus改為so。這句話的意思是“那只是空間—或者我們認為它只是空間”。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,所以關系代詞應該用whose。

            7 去掉in。result為不及物動詞,意為“形成了”,而“result in sth。”意為“導致某結果”。

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

            9 將ideas 改為idea。“idea”在表達“印象”時,為不可數名詞,不可以用復數。

            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去。
