【用法】
1.unless引导条件状语从句

They will go tomorrow unless it rains.除非明天下雨,否则他们会去那儿的。
Don’t touch the instruments unless the teacher allows you.没有老师的允许,不要乱动仪器。
(2) unless通常可以与if…not结构互换。
They will go tomorrow unless it rains.
= They will go tomorrow if it doesn’t rain.
2.as soon as引导时间状语从句
as soon as意为“一……就……”,引导时间状语从句。主句如果为将来时,从句用一般现在时。
He will come and see you as soon as he gets to our village.
他一来我们村子就会来看你。
3.so…that…引导结果状语从句
so… that…引导的结果状语从句有以下几种形式:
(1)主语+谓语+so+形容词/副词+that从句
The wind was so strong that we could hardly move forward.
风那么大,我们几乎不能前行。
(2) so+形容词+a/an+单数名词+that从句
It was so hot a day that they all went swimming.
天那么热,他们都去游泳了。
(3) so +many/few+复数名词+that从句

我没多少钱,以至于买不了手机。
【注意】当that引导的结果状语从句是肯定句时,so…that可以与be…enough to do进行转换。当that引导的结果状语从句是否定句时,可与too… to或be not… enough to do进行转换。

参考答案
1.As soon as 2. so that 3.unless 4. so that 5.As soon as 6.unless
1.句意:这个男人一说完,愚公就说,他的家人可以在他死后继续移山。根据句意可知,前半句“the man finished talking”是描述愚公说话的时间,应用as soon as“一……就”引导时间状语从句。故填As soon as。
2.句意:因为它们太大了,所以要花很长时间才能走到另一边。分词句子可知,本句考查句型so+形容词+that从句,表示“如此……以至于……”,so...that引导结果状语从句。故填so;that。
3.句意:这个故事提醒我们,你永远不知道什么是可能的,除非你试图让它发生。根据句意可知,“you try to make it happen”是前半句“you can never know what’s possible”的否定条件,所以用unless“除非”引导条件状语从句。故填unless。
4.句意:我妹妹太激动了,以至于昨晚她睡不着。分词句子可知,本句考查句型so+形容词+that从句,表示“如此……以至于……”,so...that引导结果状语从句。故填so;that。
5.句意:她一回到家,就打电话给她的朋友。根据句意可知,前半句“she returned home”是描述她给朋友打电话的时间,所以用as soon as“一……就”引导时间状语从句。故填As soon as。
6.句意:除非我取得好成绩,否则我父亲不能给我买自行车。根据句意可知,“I get good grades.”是“My father can’t buy a bike for me”的否定条件,所以用unless“除非”引导条件状语从句。故填unless。
7.A
句意:我一下飞机就会去看望我的祖父母。
考查时间状语从句。as soon as一……就……”,引导时间状语从句;as far as就……而言;远至;直到;as long as只要(引导条件状语从句),与……一样长;as easily as和……一样容易。根据“I will go to see my grandparents…I get off the plane”可知,句子要表达下飞机这个动作完成后立刻就去看望祖父母,即“一……就……”。故选A。
8.B
句意:假期一开始,格林一家总是去有趣的地方。
考查时间状语从句。but但是;as soon as一……就……;so因此;although尽管。根据“go somewhere interesting ... the holiday begins”可知,假期一开始就去有趣的地方,用as soon as引导时间状语从句。故选B。
9.A
句意:珍妮一回来我就告诉她这个好消息。
考查动词时态。as soon as引导时间状语从句,时态遵循“主将从现”的原则,主句用一般将来时,从句用一般现在时;从句主语是she,因此谓语动词用单数第三人称comes。故选A。
10.C
句意:船长是如此骄傲以至于他最后被希腊人抓住了。
考查so … that引导结果状语从句。too...to...太……而不能……;enough…that…搭配错误;so...that...如此…… 以至于……;enough...to...足够去做……。第二空后“he was seized by the Greeks at last”为句子,所以这里不能用不定式符号to,排除A和D;enough“足够地”,副词,修饰形容词或副词时要放在所修饰词的后面,即proud enough,排除B;“so”后面接形容词或副词,“that”引导结果状语从句。“proud是形容词,“he was seized by the Greeks at last”是一个句子,符合“so...that...”的用法。故选C。
11.A
句意:空调不工作了。教室里如此地热以至于没有人能忍受。
考查副词用法。so那么地;such如此的或如此地;too太……;very非常地。根据“It was ... hot in the classroom that nobody could stand it.”可知,后面有that,且后接形容词hot,应为“so + 形容词+that”结构。故选A。
12.A
句意:这个人工湖太美了,许多游客都来参观。
考查副词词义辨析。so如此,修饰副词或形容词;such如此,修饰名词;very非常,修饰形容词或副词;too太,修饰副词或形容词。根据that可知,应用so/such...that...表示如此……以至于……,空后为形容词,用so修饰。故选A。
13.C
句意:你不能进入图书馆,除非你有身份证。
考查连词辨析。if如果;when当……时;unless除非;although虽然。根据“You can’t go into the library ... you have ID card.”可知,是指除非有身份证,否则不能进入图书馆,用unless引导条件状语从句。故选C。
14.B
句意:除非他尽力并且永不放弃,否则没有人能成功。
考查连词辨析。if如果;unless除非;after在……之后;although尽管。根据“Nobody can succeed ... he tries his best and never gives up.”可知,只有“unless”符合语境,表示条件关系,强调“不尽力且不放弃”就无法成功。故选B。
15.B
句意:天太冷了,你不能出去,除非你穿上厚衣服。
考查连词辨析。if如果;unless除非;once一旦;when当……时。根据“It is so cold that you can’t go outside ...fully covered in thick clothes.”可知,天气很冷,除非穿着厚衣服,否则不能出门。故选B。
16.B
句意:——玛丽功课做得怎么样?——除非她更加努力学习,否则考试就会不及格。
考查连词。after在……之后;unless如果不,除非,表示条件;as soon as一……就……;when当……时候。根据句意可知,更加努力学习是考试及格的条件,unless符合句意。故选B。
17.D
句意:除非他答应今晚10点前回来,否则妈妈不会让Dick出去的。A. if如果;B. when 何时;C. since自从;D. unless除非。从句意来看,这里需要一个表假设的连词,说明后句是表假设的条件状语从句,结合选项,unless可以引导一个表假设的条件状语从句,意为"除非",相当于if not,故答案选D。
点睛: if引导的条件状语从句,当主句是一般将来时,从句用一般现在时表示将来的含义,就是我们常说的“主将从现”,unless也有类似的用法,unless作为连词引导条件状语从句时,可以表示“如果不”或“除非”,unless=if not,如:We will go to the park if it doesn’t rain tomorrow. 可以改写为:We will go to the park unless it rains tomorrow.
18.B
句意:除非我们为顾客提供更好的服务,否则我们的生意就不会好转。because因为,引导原因状语从句;unless除非,引导条件状语从句;after在…之后,引导时间状语从句;since自从,引导时间状语从句。根据主句Our business won’t improve以及从句中offer better service可知,从句中也应表示否定的意思,unless相当于if…not,“如果不”,符合句意,故选B。
19.C
句意:他一到这里我就给你打电话。as soon as引导的时间状语从句,遵循“主将从现”的原则,也就是当主句是一般将来时态时,从句用一般现在时态,从句中的主语he是第三人称单数,动词要用三单形式,故答案为C。
20.B
句意:那个故事是如此有趣以至于每个人非常喜欢它。So+形容词或副词+that从句,表示如此……以至于……;such+a/an+形容词+that从句,表示如此一个……以至于……。Interesting是形容词,这里用so。根据题意,故选B。
21.B
句意“-恐怕电子书对我们的眼睛有害。-但是只要我们合理使用他们,他们就对我们有帮助”。A.一……就……(引导时间状语从句);B.只要(引导条件状语从句);C.尽管(引导让步状语从句);D.目的是,为的是(引导目的状语从句)。根据句意可知,译为“只要我们合理使用他们”,表示条件,故选B。
