Sixty-five million years ago, according to some scientists, an asteroid bigger
than Mount Everest slammed into North America, (which, causing plant and
animal extinctions, marks) the end of the geologic era known as the Cretsceous
Period.
答案为(E) an event that caused the plant and animal extinctions that marks
我想请问
1.为什麽animal前面不用加"the"?
2.最後的那个"that marks"该怎麽解释?那个that指的是?
谢谢大家

1F:推 colakane:the (plant and animal) extinction"S" 02/19 02:07
2F:→ colakane:2.E选项应该是that mark,没有s,that指的就是 02/19 02:09
3F:→ colakane:extinctions,复数名词对应mark 02/19 02:11
4F:推 colakane:意思是说动植物的灭绝标记着geologic era的结束 02/19 02:13
