我刚回答的一个问题,
是这样回答的当时我回答第3题是这样的：in删掉（不定式作定语时,当所修饰的名词为place/time/way时,不定式后的介词习惯上省略.注：非以上三个词,要记得有介词.如I'm looking for a room to live in.）
后来再修正如下：
1.(for→of)
2.（your→my）
3.（It后面加个is）
4.(rapid－rapidly)
5.（More－Many）
6.（Besides －However）
7.（rush －rushed）
8.（doing－done）
9.（or－and）
10.(正确）
怎样是对的?
第5题再这样改：people前面加its，
