Let's _______ a talk about learning Chinese.

Let's _______ a talk about learning Chinese.
A. had B. having C. to have D. have
这道题怎样做?各位仁兄帮帮忙!急!
He will go to the market if it ____ tomorrow.
A. won't rain B. doesn't rain C. isn't rain D. isn't raining
还有这题,也请帮帮忙!

请看下面几句话:

Let's go swimming this afternoon.(让我们今天下午去游泳吧!)

Let's do the exercise.(让我们做运动吧!)

Let's jump into the water.(让我们跳到水里吧!)

Let's play a game.(让我们做个游戏吧!)

同学们,你们发现let's后面的动词有什么特点了吗?对了, let's后面所接的必须是动词原形, 是没有任何词形变化的。你们一定要记住哟!
1. if 引导的条件句中,如果所说的与事实相反,则要用虚拟语气。其具体的规则如下:

主句
从句

与现在事实相反
Would/should/could+动词原形
一般过去时

与过去事实相反
Would/should/could have done
过去完成时

与将来事实相反
would/should/could/might/动词原型
动词的过去式should +动词原型 were to +动词原型

1) If I were you, I would not accept his offer.

如果我是你,就不会接受它的建议。

2) If it should rain tomorrow, the race would be put off.

如果明天下雨,比赛将会推迟。

3) If you had been more carefully, you would have passed.

4) If it were not for the learning tower, the city of Pisa wouldn’t be so famous.

如果没有斜塔的话,比萨称也不会这么有名。

2.混合时态虚拟语气 很多情况下,从句和主句并不于同一时间的事实相反,这时需仔细判断其所述情景,运用适当的语气和时态。

1) If you had followed my advice, your English would be much better.

如果你当时听了我的话,现在你的英语就会好得多了。(从句与过去事实想相反,主句与现在事实相反)

2) If he weren’t a kind-hearted man, he wouldn’t have helped such a man as you that day.

(从句是与一般特性相反的假设,主句表示与过去事实相反的结局。)

3) If it hadn’t been for you, I would have to make another trip there tomorrow.如不是你的话,我明天还要再走一趟。(从句与过去事实相反,主句与将来事实相反。)

4)If I were you,I wouldn't have missed the film last night.如果我是你,我就不会错过昨天晚上的那部电影。(从句与现在事实相反,主句与过去事实相反。)

5)If he had followed the doctor's advice,he would recover already.如果他遵照医生的劝告,现在病就好了。(从句与过去事实相反,主句与现在事实相反。)

3.在if虚拟条件句中,有时可把连词省去,采用倒装语序把谓语动词were或助动词had,should移到句首构成非真实条件从句的另一种句型,其意思不变。例如:

1)Had we time to spare,we would be glad to go to the park.如果能抽出时间,我们很乐意逛公园。

2)Were it not for the discovery of electricity,the modern world would experience great inconvenience.假如没有发现电,现代世界将很不方便。

3) Should I get a rise, I would treat you to whisky.如果我能长工资,就请你喝威士忌。

4.有时假设的情况不用if引导虚拟条件从句来表述,而用介词(如without, but for等)引出的短语、分词(如supposing等)引出的短语、并列连词(如or,otherwise,but,though等)、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。例如:

1)But for your advice,I would not be able to do this work.要不是你的劝告,我是不会做这份工作的。

2)Victor obviously doesn't know what's happened,otherwise he wouldn't have made such a stupid remark.显然维克多不知道发生了什么事情。不然的话,他就不会说这样愚蠢的话了。

Let's __have_____ a talk about learning Chinese.
理由是let后面要加原型

He will go to the market if it ___ doesn't rain _ tomorrow.
理由是四个字:主将从现!!

第一道:D
Let's 后接动词的原形,故选D

第二道:B
考的是时间状语从句,主句将来时,从句用一般现在时故排除AD
而rain有两种词性,一种是“雨”的意思,是名词。it isn't rain 的意思是这不是雨的意思,不符合句意;另一种是动词“下雨”的的意思。it doesn't rain的意思是不下雨。根据句意应选B。

绝对准确!!!!!!!

Let's _have__ a talk about learning Chinese.

He will go to the market if it __won't rain __ tomorrow.

D B
1.因为Let后面的动词要用原型,A是过去式,B是现在分词形式 C是动词不定式
所以选择D
2.因为If在这里是引导条件状语重句,要用一般现在时。就只有B,C选项
而rain是名词,就要用do,或does及他们的否定形式,所以选择B
绝对正确。我们上次考试有雷同的题目,是初二的吧?
