作介词后的宾语从句 I’m worried about whether we should study each other,
跟不定式to do Have you decided whether to go with us.
定语从句的用法
定语从句中只能使用that的情况
1.当先行词为anything,everything,nothing等不定代词时,只能使用“that”。
例:Is there anything that I can do for you?(我能给你做点什么吗?)
2.当先行词为all,any,much,many词时,只能使用“that”。
例:Tom told her mother all that had happened.(汤姆把事情的全部情况告诉了他的妈妈。)
3.当先行词是形容词最高级或被形容词最高级修饰时,只能使用“that”。
例:This is the most wonderful time that I have ever had. (这是我度过的最美好的时光。)
4.当先行词是序数词修饰时,只能使用“that”。例:
He was the first person that passed the exam.他是第一个通过考试的人。
5.先行词被the only,the very,the same,the last修饰时,只能使用“that”。例:This will be the last chance that he can get.(这将会是他得到的唯一机会。) He is the only person that can help you out.(他是唯一能帮你的人。)
6.先行词里同时含有人或物时,只能使用“that”。
例:They talked of things and persons that they remembered in the school.(他们谈论他们记得的有关学校的事和人。)
7.当主句是以who,which开头的特殊疑问句或先行词是who时,只能使用“that”。
例:Which is the book that he bought from the library yesterday?(哪本是你们昨天从图书馆借的书?)
注意:●指物时,在介词后只能用which,而不能用that.
●定词从句修饰代表地点、时间的先行词时,要看代表先行词的关系词在定语从句中是否作谓语动词的宾语.如作动词的宾语,就要用关系代词that 或which引导定语从句.反之,要用关系副词 where(表地点)或 when(表时间),在定语从句中作状语.
如:Mary would never forget the evening when she lost the book. I’ve been to the city that you visited last week.
被动语态注意事项
●构成
被动语态表明一个被动性动作,它由“助动词be+及物动词的过去分词”构成。
一般现在时 am/is/are pp.
一般过去时 was /were pp.
一般将来时 will be pp. am/is/are going to be pp.
情态动词 may/ can/ must/ should be pp.
被动语态否定式为be not pp.,
情态动词被动语态否定式为情态动词+not be pp..
●主动语态变为被动语态时,通常将主动语态中的宾语变为被动语态的主语;主动语态的主语变为由介词by引导的宾语;谓语动词变为被动语态“be 过去分词”形式,例如:
Everyone likes the interesting film. (主动语态) → The interesting film is liked by everyone. (被动语态)
They used knives to cut things. (主动语态) → Knives are used to cut things. (被动语态)
●某些动词可以跟双宾语如give、pass、bring、write;buy、make等,在变为被动语态时如果直接宾语变为被动语态中的主语,则间接宾语通常由介词to、for引出。例如:
My sister gave me a nice watch for my birthday. →A nice watch was given to me by my sister for my birthday.我过生日时收到了姐姐的一块手表。
They have bought us many books. → Many books have been bought for us by them. 很多书都是由他们给我们买的。
●某些动词make、hear、see、watch等在主动语态中,其宾语补足语要求用不带to的不定式。但在变为被动语态时通常省略的不定式符号to必须恢复。如:He made us clean the classroom after school. →We were made to clean the classroom after school. 我们被迫在放学后打扫教室。
I saw him come into the room. → He was seen to come into the room. 人们看见他进了屋子。
●在主动语态中如果谓语动词是含有介词或副词的短语动词,变为被动语态时不能丢掉该介词或副词。如:
They must take good care of the children. → The children must be taken good care of. 孩子们必须小心照看。
●英语中某些动词如sell、lock、draw、smell、touch、feel、sounds、write、be worth doing、sth. needs doing等可以用主动表示被动意义。如:This kind of books sells well. 这种书畅销。 The door won’t lock. 门锁不上。
