  参考答案及解析:
, Y+ n) F5 }0 D  supernova 名词,[天]超新星; Y/ h  D& u2 e$ G: C7 ~
  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。5 Z. N) x* Z; s# \9 q6 L& V
  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。+ \3 c/ y8 ~" @( y
  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”。! @5 m2 }7 G  u' W3 d8 F
  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。# [$ y) g1 o, o" U* s( L
  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。
3 u. o5 y8 [7 v: J  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。
* G6 Q, f9 w; Y8 l+ v  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”。* l4 X3 A; x# F/ D/ Q- L4 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。% q: R: L. J3 W3 X
  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。
) b3 k0 B$ ?. P( t1 D, n. m  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。7 }! V; w* R3 A/ W
