三、状元笔记
解题思路
1. 找准相关动词的逻辑主语,确定该动词与逻辑主语间是什么关系(主动还是被动);
2. 搜索句子中相关的时间信息,确定非谓语动词的恰当形式(一般式还是完成式)
考点三 动名词的重要用法
1. 动名词具有名词的特性:作主语、宾语、表语等,可用于介词后。
【例句】 (1)His coming made us happy. 他的到来让我们感到高兴。
(2)He devoted his life to helping others. 他一生致力于帮助别人。
2. 动名词作宾语时,其逻辑主语可用形容词性物主代词(my,his)或名词性物主代词(me,him)。动名词作主语时,其逻辑主语要用形容词性物主代词。
【例句】Do you mind my/me smoking here? 你介意我在这里抽烟吗?
3. 动名词的被动式为:being done
【例句】He is afraid of being laughed at. 他害怕被嘲笑。
4. 重要句型:
【例句】It is no use talking to him. 跟他谈话没用。
状元典例
He is looking forward to _____________________________(there be)a chance。
答案:there being 思路分析:look forward to 后要接doing。

2. 下列结构中用不定式作主语补足语:
sb. be said/ believed / known / reported / considered / found/ thought + to do / to have done (to be done/ to have been done)
【例句】

【例句】If the weather permits, we’ll go out.
