（2）before在引导时间状语从句时，表达“在……之前”的意思，

3．Then she swam to the shoreafter spendingthe whole night in the water.她在海里游了整整一夜才游到岸边。

介词after的宾语是动名词spending及这个动名词的宾语、状语，这个结构在意义上等于aftershe had spent the whole night in the water。

到达岸边后，姑娘朝着她看到的灯光方向挣扎着往峭壁上爬去。

“on+ 动名词”相当于as soon as或when引导的时间状语从句，强调在那一时刻发生的：On reaching the airport, he was arrested by the police.

他一到机场就被警察逮捕了。

7．That was all she remembered.她所记得的就是这些。

that指前面（从第2句话开始）描述的内容。sheremembered为all的定语从句，关系代词that（不能用which）被省略了。
