二、句型活用1.sothat如此以至于【典型例句】the bus was so full that i could hardly turn around.公共汽车上挤得我几乎无法转身。we were so tired that we cant go any further.我们太累了，再也无法往前走了。【知识归纳】so +adj./adv.+that意为“如此以至于”，引导结果状语从句。【相关链接】引导结果状语的结构还有：bob is so tall a man that he can almost reach the ceiling.鲍勃个子这么高，几乎够得着天花板。i have had so many falls that im black and blue all over.我跌了这么多跤，浑身青一块紫一块的。there was so little water left that only small children and patients were given some.留下的水不多了，只给小孩和病人分了一些。例如：he is such a good teacher that we all love him.他是个很好的老师，我们都很喜欢他。drug dealers are such dangerous persons that people are afraid of them.毒品交易人员是一群危险的人，其他人都很害怕他们。it was such loud music that we couldnt hear ourselves speak.音乐声音太大，我们听不到自己的说话了。注意：“so little+不可数名词+that从句”结构中的little如果不表“数量(少)”之意，而当“小”讲时，则用such little+可数名词复数或such a little+单数可数名词。2.there was nothing to be done不定式作后置定语【典型例句】there are a lot of clothes to wash.(我)有许多衣服要洗。the secretary asked his manager,“do you have any files to be typed?”秘书问经理：“你有文件要打吗？”(打文件的不是you经理)there was nothing to do.(我)无事可做。there was no time to lose.(咱们)没时间可浪费。there were plans to be made at once.要立即制定计划。【知识归纳】其中to be done是不定式作后置定语，修饰nothing。不定式用被动式强调客观上不允许有所行为。作定语的不定式用主动还是被动形式取决于两个条件：其一，不定式与所修饰成分有被动关系，且与句中主语有主谓关系时，不定式用主动形式；其二，不定式与所修饰成分虽有被动关系，但与句中主语并无主谓关系时，不定式则用被动式。3.连系动词appear的用法总结【典型例句】he appears to want to leave.他似乎想离开。she appears to have been told everything.似乎已经有人告诉了她一切。【知识归纳】appear为连系动词，其后接不定式作表语。to have increased 为不定式的完成式，表示该动作发生于谓语动词appear的动作之前。【相关链接】区别appear,seem,look(看起来)意义区别：appear强调外表给人的印象，有时含实质上并非如此的意思。he appears to know more than he really does.他看起来好像懂很多，其实不然。seem暗示有一定根据的判断，这种判断往往接近事实。his health seems to be better.他的健康状况似乎有所好转。look着重从视觉得出的印象。he doesnt look like his age.他看起来比实际年轻(或老成)。句型特点：例如：他看起来相当快乐。看起来仿佛快要下雨了。i seem/appear to have seen him somewhere.我好像在哪儿见过他。4.cant help but不由得【典型例句】i cant help but wonder what will happen.我禁不住想要知道会发生些什么。i cant help but think that it was a mistake.我不禁认为那是一个错误。i cant help but love her.我不禁爱上了她。he cant choose but do it.他只好做这件事了。【知识归纳】cannot help but;cannot but;cannot choose but之后的不定式一般都不带to,常译为“不得不”。【相关链接】cant/couldnt help doing忍不住i couldnt help laughing when i saw her funny expression.看到她滑稽的表情，我禁不住大笑起来。i couldnt help crying.我禁不住哭了。5.i couldnt agree with you more.否定词与比较级连用表示肯定的意义【典型例句】ive never heard a better voice.我从未听过这么好的嗓音。they couldnt have done better.他们打得好极了。it couldnt be worse.太糟了。【相关链接】y
