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__6 j( B0 _+ S5 ^: R2 M: w9 s
  答案:supernova 名词,[天]超新星" u7 _; d1 o3 N
  1 将as 改为since或者because。在表示原因的连接词中,只有as引导的原因状语从句不能位于主句之后,只能位于句首。. e# V+ _8 ]0 O  [$ h2 U1 u
  2 将adequate 改为inadequate,或者在are后加not。从逻辑上分析,因为我们拥有的科学术语“不充足”,所以才无法回答这个问题,所以用否定形式。
$ j& m0 B% }, V  3 在which 前加into。这是一个定语从句,意思是“黑洞是太空中物质可以掉进去的地方”,所以定语从句应该为“into which matter has fallen”。
8 r' g7 r, f! O) `9 {  4 将but 改为 so。 上文已提到“连光都无法从黑洞中逃出”,所以我们根本无法看到黑洞。这里应该是因果关系,而不是转折关系。
& A7 \( t8 P, a  5 将thus改为so。这句话的意思是“那只是空间—或者我们认为它只是空间”。so做 think 的宾语,thus 只能做连词,不能做宾语。; }* ?. j9 \( e% Z3 W! M* l
  6 将which 改为whose。这个定语从句的意思是“它是一颗星,其密度非常大,由于自身的引力,它在不断地收缩”。matter 属于star,所以关系代词应该用whose。
1 d; [) I2 I$ h- S  d8 H4 L  7 去掉in。result为不及物动词,意为“形成了”,而“result in sth。”意为“导致某结果”。
2 X, n; h& Y; l# W, @8 I4 j  8 将masses 改为mass。mass 可指“大量的物质”,而“the masses”特指“劳动群众”,用在此处不妥。5 R1 D0 m: U7 z4 l2 I0 m$ ?
  9 将ideas 改为idea。“idea”在表达“印象”时,为不可数名词,不可以用复数。  ?- P0 X6 }! f/ ~2 f8 K: o4 g
  10 将no改为any。分析便知,任何在黑洞附近的东西都会被吸进去。
