Analyze the important sentences among the text
1. Well, it's difficult to answer this question, since the terms we would normally use to describe a scientific phenomenon are inadequate here.(p1)
译：哦，这个问题很难回答，因为我们通常用来描述一种科学现象的现有术语在这里不够用。
句子分析：it是形式主语，to answer this question是句子主语;since引导原因状语从句，we would normally use to describe a scientific phenomenon是定语从句，修饰terms; inadequate: 不充分的，不合格的。
2. Astronomers and scientists think that a black hole is a region of space not a thing into which matter has fallen and from which nothing can escape---not even light. (p1)
译：天文学家和科学家认为黑洞是一个空间区域，而不是一个物体，物质会掉进黑洞而没有物体可以从中逃脱出来，即使是光也不行。
句子分析：into which和from which引导两个定语从句，介词：into和fall搭配;from 和escape搭配。这种介词+which的定语从句的形式请多注意。
3. The theory is that some stars explode when their density increases to a particular point. (p2)
译：(关于黑洞形成的)理论就是一些星球的密度增长到某个特定的点就会爆炸。
句子分析：这是一个主系表结构句。that用来引导表语从句，不可省略。其中又包含一个when引导的时间状语从句。to a particular point是达到某一个特定的点的含义。
4. But if the star is very large (much bigger than our sun) this process of shrinking may be so intense that a black hole results. (p2)
译：但如果星球很大(比我们的太阳还要大得多)，其收缩过程可能很剧烈，以致于产生了黑洞。
句子分析：这是一个if引导的条件状语从句，so…that表示如此…以致，是结果状语从句。
如：I'm so tired that I can even sleep on my way home.
5. Imagine the earth reduced to the size of a marble, but still having the same mass and a stronger gravitational pull, and you have some idea of the force of a black hole. (p2)
译：假想一下地球收缩到弹球儿那么大，但仍具有同样的质量和更强的吸引力，你就会对黑洞的力量又某种概念。
句子分析：该句的主要结构为imagine….and you ……事实上相当于if you imagine…, you will have some idea….. 这种句子结构在历年的考试中曾出现过。请记住：祈使句+ and + 陈述句= if引导的条件状语从句。如：Hurry up and you can catch the last train!
另外，该句还有两个定语成分reduced to the size of a marble和having the same mass and a stronger gravitational pull用来修饰the earth.前者为过去分词，而后者为现在分词。词组：
have some idea of sth对…有所了解
