“主语+be+adj.(+for sb.)+to do”结构等重点句型详解知识点包括“主语+be+adj.(+for sb.)+to do”结构、当先行词是表示时间的名词时,定语从句的引导词的情况、have作使役动词时的常见结构、even if/though所引导的让步状语从句等部分,有关“主语+be+adj.(+for sb.)+to do”结构等重点句型详解的详情如下: “主语+be+adj.(+for sb.)+to do”结构Two years ago,I was told I had a serious disease which was difficult to cure. 两年前,我被告知患有一种很难治愈的严重疾病。 (1)句式分析:这是一个主从复合句。主句是I was told I had a serious disease,其中包含了I had a serious disease这个宾语从句;which was difficult to cure是which引导的定语从句,修饰先行词disease。 (2)which was difficult to cure 是“主语+be+adj.(+for sb.)+to do”结构。该结构的用法为: ①主语是不定式 to do 的逻辑宾语,所以 to do 后不能再接sth.,且 to do 用主动形式表示被动意义。如: 他是一个很容易被劝服的人。 [误]He is a person who is easy to be persuaded. [正]He is a person who is easy to persuade. ②to do 中的动词若是不及物动词,则要加上相应的介词,若是及物动词则不需要。如: 这把椅子坐起来很舒服。 [误]The chair is comfortable to sit. [正]The chair is comfortable to sit on.(sit 是不及物动词,sit on the chair) ③如果要指出不定式动作的发出者(即不定式的逻辑主语),则在 to do 前加 for sb./sth.。如: This kind of job is very easy for them to do. 这种工作对他们来说是很容易做的。 当先行词是表示时间的名词时,定语从句的引导词的情况Have you ever faced a time when things looked dark and you had no hope at all? 你是否曾经面对过一段事情看起来很黑暗且根本没有希望的时期? (1)句式分析:这是一个主从复合句。主句是Have you ever faced a time,when things looked dark and you had no hope at all是when引导的定语从句,修饰先行词a time。 (2)when引导定语从句,先行词为a time。当先行词是表示时间的名词时,定语从句的引导词有两种情况:
Do you still remember the day when we worked together? 你还记得我们在一起工作的日子吗?(作状语) Do you still remember the day (that/which) we spent together? 你还记得我们在一起度过的日子吗?(作宾语) 注意:做题时,不要一见到先行词是表示时间、地点或原因的名词就用when,where或why引导定语从句,而应看看引导词在定语从句中做什么成分。若作时间、地点或原因状语,用when,where或why;若作主语或宾语,就要考虑用that或which。 have作使役动词时的常见结构The doctor wanted me to relax,so he had me listen to some music,and one of the songs was “Happy”. 医生想让我放松,所以他让我听一些音乐,其中一首名叫“快乐”。 (1)句式分析:句中had me listen中的had (have)是使役动词。 Our office would like to have you speak to the park visitors on July 28 at 11:00 am. 我们办公室希望你在7月28日上午11点给来公园的参观者做演讲。 (2)have作使役动词时的常见结构: 结构 意义 have sb. do sth. 让某人做某事 have sb./sth. doing sth. 让……持续做某事,让……一直处于某种状态 have sth. done ①让别人做某事;②遭受……;③使某事被做 I often have Tom buy me lunch. 我常常让汤姆给我买午饭。 He had his computer stolen the other day. 前几天他的电脑被偷了。 He had us laughing by telling jokes all through the meal. 在整个就餐过程中,他一直笑话不断,让我们笑个不停。 even if/though所引导的让步状语从句To be a good daughter,I agreed to learn even though I wasn't interested in it at all. 为了成为一个好女儿,我同意学习,尽管我对它一点都不感兴趣。 (1)句式分析:这是一个主从复合句。even though引导了让步状语从句。 (2)even if相当于even though,意为“即使,尽管”。even if/though所引导的让步状语从句可用现在时代替将来时。 Even if you take a taxi, you will still miss the train. 即使你乘出租车也赶不上这班火车了。 Even if we could afford it, we wouldn't go abroad for our vacation. 即使我们付得起这笔钱,也不出国度假。 |
