May/might be doing 也许正在做 They may be watching TV now. 口诀: “情动”加上 have done,推测事情已经干; “情动”加上 be doing,推测事情在进行; 条件状语从句中的虚拟语气:条件句分为真实条件句和虚拟条件句两种, 真实条件句用陈述语气,虚拟条件句用虚拟语气。

(虚拟条件句是虚拟语气 的重点) 虚拟条件句关键是要熟练掌握以下三大公式: 三个相反 与现在事实相反 与过去事实相反 从句 主句 If sb did/were… If sb had done… Sb would/should/could/might do… Sb would/should/could/might have done/have been… 与将来事实相反 If sb did/were… If sb were to do… If sb should do… Sb would/should/could/might do… 1、宾语从句中的虚拟语气:有三种情况。

一是在动词 insist(坚持), order 命令) command(命令), ( , suggest (建议) ,advise(建议) 。

Recommend(建议,推荐) ,require(要 求),request(请求) ,demand(要求) ,desire(要求,愿望) 等动 , 词后面的宾语从句中一般用虚拟语气,其结构为“主语+should+动词 原形” 其中 should 可以省略。

, 把以上 10 个动词简称为:一个“坚持” ,两个“命令” ,三 个“建议” ,四个“要求” 。

二是动词 wish 之后接宾语从句一定要用虚拟语气。

从句的时态是: 1、与过去事实相反用 had done/had been, 2、与现在事实相反用 did 或 were, 3、 与将来事实相反用 “would/might/could/should+动词原形” 。

注意:wish 在简单句中并非表示的是虚拟语气,如: wish you success.祝你成功。

三是在 would rather 的宾语从句中,也要使用虚拟语气,其从句中 would rather you didn’t hear 谓语动词的时态用一般过去时。

如:I what I said. 少数“it 我宁愿你没有听到我说的话。

2、主语从句中的虚拟语气 is+形容词+that+主语+should+动词原形” 其中 , 样 可 以 省 略 。

常 见 形 容 词 有 : should 同 important,necessary,strange,unusual,curious,remarkable,surpri sing,desirable,natural 等。

3、定语从句中的虚拟语气 “it is(high/about) time that+主语+动词的过去式,或者 是“should+动词原形” 。

Time 是先行词,that 是引导词,其意思 是“早该做什么事了” 如:1、It is high time that you went to school.=it is high time that you should go to school.你该上学了。

2、It is about time that you picked up your daughter at school.= It is about time that you should pick up your

daughter at school.你该去学校接你女儿了。

熟 练 掌 握 强 调 句 型 : 句 型 结 构 是 : it is/was+ 被 强 调 部 分 +that/who+句子原有部分。

在强调句型中,强调人时,一般用 who, 也可用 that,但强调时间,地点等时只能用 that,不能用 when,where 等。

1、 2、 3、 4、 强调主语 强调地点状语 强调时间状语 强调宾语。

not …until…的三大句型: 例:妈妈回家之后我才睡觉。

正常 I did not go to bed until my mother come back home. 强调 It was not until my mother came back home that I went to bed. 倒装 Not until my mother came back home did I go to bed. 怎样识别 not …until…是强调句还是倒装句呢?很简单,如果否定 词 not 在句首,就是倒装句,如果 it 在句首,就是强调句。

it 的 10 大句型 1、It was for the first time that I wrote to a foreign pen friend.这确实是我第一次给一个外国笔友写信。

这是强调句型。

还原为: I wrote to a foreign pen friend for the first time. 2、It is the first time that I have written to a foreign pen friend. 这是我第一次给一个外国笔友写信 这是定语从句,that 之后的时态要用现在完成时态。

3、It was eight when the class began.8 点钟开始上课。

这是时间状语从句,强调句型: It was at eight that the class began. 4、 is possible that I will enter this key university.我上这所 It 重点大学是可能的。

这是主语从句。

It 是形式主语。

that I will enter this key university 是真 正主语。

还原成: That I will enter this key university is possible. 5、 is/has been three years since he got married.他结婚(成 It 家)已经三年了。

It is/has been some time since sb did(短暂性动词)sth.意为“自 从某人干某事已经有多长时间”例如: It is/has been three years since he worked here.他不在这儿工 作已经三年了。

6、It will be one year before she finishes middle school.再 有一年时间她就中学毕业了。

It is/was/ will be some time before…意为“过多长时间后再干 什么” 。

7、It is high time we went to school.我们上学的时间到了。

这时定语从句,在 It is(high)time that…句型中,that 之后谓 语动词的时态要用一般过去时或“should+动词原形” 属于虚拟 , 语气。

8、It is said that a new factory will be built nearby my

图5

hometown.据说一家新工厂将见在我家乡附近。

这时主语从句。

it is+过去分词+that….. 。

类似的句型还有: It is reported that…/ It is known that…/ It is thought that…/ It is suggested that…/ It is believed that…/ It is hoped that… 等。

9、It looks as if it is going to snow.看起来要下雪了。

这时表语从句,类似的句型还有: It seems to sb that…/ It (so)happened that…/ It appears to sb that(=as if)…等。

10 、 It is necessary that we should master a foreign language.我们掌握一门外语是必需的。

这是主语从句,在“It is+少数形容词+that sb should do …” 这 种 句 型 中 , it 同 样 是 形 式 主 语, that 之 后 从 句的 谓 语 动 词 是 “should+动词原形” ,其中 should 可以省略。

这样的形容词 有 necessary/important/unusual/strange/natural 等。
