专题04 重难语法精讲练

  姓名：_________ 班级：_________ 学号：_________

经典考点一：让步状语从句

(1)让步状语从句通常由although, though等连词引导。例如：

Though he is young, he knows a lot．

Although I am tired, I must go on working．

易错考点：although只能用在句首，而though既可以放句首也可以放句末。

(2)although(though)不能和but用在同一个句子中。例如：

Though it was raining hard, but he still went out． （╳）

应该说：Though it was raining hard, he still went out．或It was raining hard, but he still went out．

经典考点二：时间状语从句

时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。

It was raining hard when I got to school yesterday．

He won’t believe it until he sees it with his own eyes．

when，while，as辨析：

①when引导的从句，动词既可以是延续性的，也可以是终止性的。一般来说，当主句的动作正在进行时，when引导的从句的动作才发生；

例：He was riding to school when he was hit by a car this morning． 当他被一辆小汽车撞到的时候他正骑车上学。

②while引导的从句中，动词只能是延续性的，一般来说，当while引导的从句的动作正在进行时，主句的动作才发生；

例：They were singing while we were dancing．   我们在唱歌的时候他们在跳舞。

③as表示随着短暂动作的发生，另一行为伴随发生。

例：She sang as she walked． 她一边走一边唱歌。

★当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”( 用现在时态表示将来的动作或状态)

 since: “自从”, ★重要经典考点: 现在完成时 (主句) + since+ 一般过去时 (从句)

Mr． Green has made quite a few friends since three years ago．

It is four years since my sister lived in Beijing．

→★It is +一段时间+ since+ 从句 (一般过去时)

not…．．．．．until/ till．．．．．．．  直到……才

…．．．．．till．．．．．．．．    直到……为止

① until表示动作、状态的持续，强调“一直到……为止”，或强调某个动作或状态一直持续到另一个动作或状态出现之前。常与表示延续性动作的动词连用。
例：I waited until three o’clock, but he didn’t come．
②not … until表示“到……为止；直到……才”，常与表示瞬间性动作的动词连用。
例：The children didn’t come home until it was dark．

注意：一旦看到否定，再看到选项中有until，可以迅速联想到“not．．．．．．until．．．．．．”结构，再结合句意进行判断选择。
经典考点三：目的状语从句和结果状语从句

①so that  表示为了．．．（表目的）

②so．．．that．．．，such．．．that．．．  表示如此．．．以至于．．．

so＋形容词/副词＋that从句

例：Nanjing is so beautiful that lots of visitors come here every year．

南京如此美以至于每年许多游客来这。

so＋形容词＋a/an＋可数名词的单数＋that从句

例：Nanjing is so beautiful a city that lots of visitors come here every year．

南京如此美以至于每年许多游客来这。

so＋many/much/few/little＋名词＋that从句；

例：He had so little education that he wasn’t able to read or write．

他所受教育很少以至于他既不会读也不会写。

such＋a/an＋形容词＋可数名词单数＋that从句；

例：She is such a good girl that we all like her．

她是如此好的一个女孩，以至于我们大家都喜欢她。

such＋形容词＋不可数名词/可数名词复数＋that从句。

例：They are such interesting novels that I want to read them once again．

这些小说非常有趣，我想再读一遍。

特别提醒：

①so that引导目的状语从句时，表示“以便；为了”，从句中常使用can /could /may /might /will /would /should等情态动词或助动词；引导结果状语从句时，从句中一般不用can和may等词，在so that前可以用逗号，意思是“因此;所以”。

 ②当that引导的结果状语从句为肯定句时，so ．．． that ．．．可以与be ．．． enough to do句型转换；当从句为否定句时，可以与too ．．． to ．．． 或be not ．．． enough to do句型转换。这也是常考题型，需要注意。

③如果名词前有many, much, little, few等词修饰时，只能用so, 不用such。

例：

①The box is so light that he can carry it． = The box is light enough for him to carry．

这个箱子够轻，他搬得动。

经典考点四：原因状语从句

(1)原因状语从句通常由because, since, as引导。例如：

He didn’t come to school because he was ill．

Since you can’t answer the question, I’ll ask someone else．

(2)because表示直接原因，语气最强。because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。as和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从句多放在句首。例如：

——Why aren’t you going there?

——Because I don’t want to．

(3)because和so不能同用在一个句子里。

经典考点五：条件状语从句

(1)条件状语从句通常由if, unless引导条件状语从句时，一般遵循主将从现的原则。如果主句是一般将来时，情态动词加动词原形或祈使句时，状语从句用一般现在时。

例： I’ll help you with your English if I am free tomorrow．

(2)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。

例如：

Hurry up, or you’ll be late． =If you don’t hurry up, you’ll be late．

注意：

①unless=if…not．

如：You will get lost easily unless you have a map．

= You will get lost easily if you don’t have a map．

②if既有”如果”也有“是否”的意思。作“如果”讲时遵循主将从现的原则，作“是否”讲时引导宾语从句。

例：I don’t know if he will come back tomorrow．

经典考点六：比较状语从句

比较状语从句，只用于两者之间进行比较的情况下，通常由as…as, 比较级 + than…等连词引导，一般和比较级连用。例如：

参考答案

1． A

【详解】句意：我们生活在一个快速发展的世界里，除非我们不断学习，否则我们将被落在后面。

考查连词辨析。unless除非；if如果；after在……之后；though虽然。“we keep learning”是“we will be left behind”的否定条件，用unless引导条件状语从句。故选A。

2． C
