The most important thing is to negotiate with them about the future of the plant (2)动名词作表语:动名词作表语,表示抽象的一般性的行为。 Our work is serving the people我们的工作是为人民服务。 His hobby is collecting stamps他的爱好是集邮。(注)动名词作表语时与进行时态中的现在分词形式相同,但其所属结构迥异,进行时态说明动作是由主语完成的。动名词做表语,说明主语的性质或情况。 People cannot but feel puzzled,for they simply cannot understand how he could have made such a stupid mistake. His victory in the final was no more convincing than I had expected (3)分词作表语 分词做表语有两种情况,一种是现在分词做表语,一种是过去分词做表语,这两者区别是考试中经常考到的地方。一般来说,表示心理状态的动词如excite,interest等都是及物动词,汉语意思不是“激动”,“高兴”,而是“使激动”、“使高兴”,因而现在分词应该是“令人激动的”、“令人高兴的”,过去分词则是“感到激动的”和“感到高兴的”。所以,凡表示“令人的”都是-ing形式,凡是表示“感到”都用-ed形式。换句话说,若人对感兴趣,就是somebody is interested in.,若人/物本身有兴趣时,就是说sb./sth. is interesting.这类词常见的有: interesting使人感到高兴-interested感到高兴的 exciting令人激动的-excited感到激动的 delighting令人高兴的-delighted感到高兴的 disappointing令人失望的-disappointed感到失望的 encouraging令人鼓舞的-encouraged感到鼓舞的 pleasing令人愉快的-pleased感到愉快的 puzzling令人费解的-puzzled感到费解的 satisfying令人满意的-satisfied感到满意的 surprising令人惊异的-surprised感到惊异的 worrying令人担心的-worried感到担心的 Travelling is interesting but tiring旅行是有趣的,但是使人疲劳。 The pupils will get confused if they are made to learn too much如果要学生学得太多,他们会感到糊涂的。 The argument is very convincing他的论点很令人信服。 They were very excited at the news听到这个消息,他们非常激动。 3不定式和动名词作宾语的区别 英语中大多数动词既可跟不定式,也可跟动名词作直接宾语,但有些动词要求: (1)不定式做宾语和宾语补足语 1)下面的动词要求不定式做宾语 attempt企图 enable能够 neglect忽视 afford负担得起 demand要求 long渴望 arrange安排 destine注定mean意欲,打算 begin开始 expect期望 omit忽略,漏 appear似乎,显得 determine决定 manage设法 cease停止 hate憎恨,厌恶 pretend假装 ask问 dread害怕 need需要 agree同意 desire愿望 love爱 swear宣誓 volunteer志愿 wish希望 bear承受 endeavor努力 offer提供 beg请求 fail不能 plan计划 bother扰乱;烦恼 forget忘记 prefer喜欢,宁愿 care关心,喜欢 happen碰巧 prepare准备 decide决定 learn学习 regret抱歉,遗憾 choose选择 hesitate犹豫 profess表明 claim要求 hope希望 promise承诺,允许 start开始 undertake承接 want想要 consent同意,赞同 intend想要
