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)

譯：哦，這個問題很難回答，因為我們通常用來描述一種科學現象的現有術語在這里不夠用。

句子分析：it是形式主語，to answer this question是句子主語;since引導原因狀語從句，we would normally use to describe a scientific phenomenon是定語從句，修飾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)

譯：天文學家和科學家認為黑洞是一個空間區域，而不是一個物體，物質會掉進黑洞而沒有物體可以從中逃脫出來，即使是光也不行。

句子分析：into which和from which引導兩個定語從句，介詞：into和fall搭配;from 和escape搭配。這種介詞+which的定語從句的形式請多注意。

3. The theory is that some stars explode when their density increases to a particular point. (p2)

譯：(關于黑洞形成的)理論就是一些星球的密度增長到某個特定的點就會爆炸。

句子分析：這是一個主系表結構句。that用來引導表語從句，不可省略。其中又包含一個when引導的時間狀語從句。to a particular point是達到某一個特定的點的含義。更多上海自考串講筆記請聯系上海自考在線老師【點擊咨詢】
