今天将的要点主要为三处 ①must be doing一定正在干什么 could have done/might have done 可能做了某事 couldn’t have done 不可能干过某事 needn‘t have done本不必做某事 should have done/should not have done =ought to have done/ought not to have done 本应该做而没有做/本不该做而做了
③ as if似乎 好像as though even if即使 纵然 就是 哪怕 even though with的复合结构后不接句子 with + 宾语 + doing (表示主动,正进行) He lies there, with his eyes looking at the window. with + 宾语 + do+ed(表被动) All the afternoon he worked with the door locked. with + 宾语 + 动词不定式,即:to do(表将来) (to do无被动形式)→_→ I can’t go out with a lot of homework to do with the windows open(adj.) with time going by(v·ing) with a book in his hand (prep phrase) with a lot of difficlut prombles settled(v·ed) with a lot of homework to do(to do)
①V-ing 作伴随状语表示动作发生的过程 I stood under the tree reading the newspaper. The girl was sitting on the bench in the park burying herself in the book. without 为介词 介词+V-ing 常考查被动 without being dealt with
③当that前十单数可数名词且该名词前面有形容词修饰时 so + adj.+a/an +n.或such+a/an + adj.+n. It was such a fine day/so find a day 在so…that…的结构中 若将so+adj./adv.置于句首 其后的 主语要用部分倒装 So cold was the weather (原The weather was so cold) that we had to stay at home. So fast does light travel (原Light travels so fast ) that it is hard for us to imagine its speed. 部分倒装,将助动词(dose do did have has had)系动词(am is are was were) 情态动词(①只做情态动词:must,can(could),may(might),ought to ②可做情态动词又可做实义动词:need,dare ③可做情态动词又可做助动词:shall(should),will(would) ④有情态动词特征:have(had) to,used to)提到主语前面 I love you→do I love you He loves you→dose he love you I loved you→did I love you I am love it→am I love it I can do it→can I do it I have/had finish it→have/had I finish it he has been doing/has he been doing(过去完成时)
首先了解四个术语 定语 定语从句 先行词 关系词 定语:定语是用来限定、修饰名词或代词的,定语是对名词或代词起修饰、限定作用的词、短语或句子,汉语中常用‘……的’表示。 定语从句:修饰某一名词或代词的从句。 先行词:被修饰的名词或代词叫先行词。 关系词:引导定语从句的关联词称为关系词,关系词有关系代词和关系副词 关系代词 that which who whom whose as 关系副词 where when why等 关系词有三个作用 ①引导定语从句 ②代替先行词 ③在定语从句中担当一个成分
二、限制性定语从句和非限制性定语从句 1. 限定性定语从句:对先行词起到修饰限制的作用,使该词的含义更具体,更明确。这类从句不能省掉, 否则句子的意义就不完整。 I was the only person in my office who was invited. 我是我办公室唯一被邀请的人 2. 非限定性定语从句:同主句的关系不十分密切,只是对先行词作附加或补充的说明,不起限制的作用,如 果省去,主句的意思仍然清楚完整。这类定语从句在书写时大多用逗号与主句分开。 Last week I met John, who seemed to be very excited. 上个星期我遇见约翰 他看起来很激动
三、关系代词: A. that 指人/物,作主语或宾语 1. A plane is a machine. It can fly. A plane is a machine that can fly. 2. He is the man. I told you about him. He is the manthat I told you about.
B. which 指物,作主语或宾语 1.These are some trees. They were planted last year. These are the trees whichwere planted last year. 2. This recorder is made in Japan. He is using it. This recorder which he is using is made in Japan.
C. who指人,作主语或宾语。 1. The man is our teacher. I talked with him. The man who I talked with him is our teacher. 2. Wang Lin is our monitor. She is 16 years old. Wang Lin who is 16 years old is our monitor.
