what they could do 还是what they could to do
有这样一道题，我们先来看看：
The soldiers tried their best and did what they could_________ against the flood. A. fight B. to fight C. fighting D. fought
【分析】有的同学一看到空格前的情态动词 could 就断定此处应填动词原形 fight，即断定选A答案。其实选错了，正确答案应是B。这是一个省略句，即在 could 后省略了动词 do，若把句子补完整应为The soldiers tried their best and did what they could do to fight against the flood (士兵们竭尽全力抗洪)。即句中的不定式短语 (to fight against the flood) 用作目的状语的，而不是与情态动词(could)一起构成谓语。请再看类似例句：
(1) He did what he could to help us. 他尽力帮助我们。
(2) He saved what he could to buy a car. 他尽量节约每一分钱以便买车。
(3) He ran as fast as he could to catch the early bus. 他拼命地跑以便赶上早班车。
至此，有的同学可能又会想当然地认为，今后只要遇到类似结构的题选带to不定式就万事大吉了，但也不一定，例外还是有的，还得具体问题具体分析。请看下例：
(4) He ran as fast as he could _________ to catch the early bus.
常用英语词汇辨析
A. to hope B. hope C. hoping D. hoped
若根据以上“经验”认为此题要选A答案，那就又错了。此题应选 C，其中的现在分词短语 hoping to catch the early bus 用作伴随状语。
(5) He spent every minute he could _________ spoken English.
A. practise B. to practise C. practising D. practised 【分析】此题应选 C，它与以上各题的情形均有所不同，虽然与上面的第(4)题的答案一样，均为动词的 –ing 形式，但也不完全一样：第(4)的 hoping 为现在分词，在句中用作伴随状语；而此题的 practising 是动名词，之所以用它与前面动词 spent 的搭配有关，即 spend … (in) doing sth。若将此句补充完整，即为 He spent every minute he could spend in practising spoken English.
(6) Mr Smith made up his mind to devote all he could _________ his oral English before going abroad. A. improve B. to improve C. improving D. to improving
【分析】此题答案选D，注意两点：一是 devote … to … 是固定搭配，意为“把……贡献给……”；二是其中的 to 是介词，不是不定式符号，后接动词时要用动名词。 so / such,so...that / such...that 用法辨析
使用注意事项：
1. so为副词，一般修饰形容词和副词。such为形容词，修饰名词。so fast, such a nice picture。
2. so也可修饰名词，但必须符合以下语序：so+形容词+a/an+名词。即so后面的名词必须为可数名词单 数形式。so big a dog=such a big dog。如用了复数只能说such big dogs。
3. 与many, much, few, little这四个表示“数量”的词连用只能用so。需要提醒的是，little还可作为“小” 的意思，这个时候仍然用such。I have never seen such little sheep before.
4. 当so…that引导的结果状语从句为肯定句时，可与be…enough to do替换；当为否定句时，可与too… to…或be not…enough to do替换。 He is so young that he can’t go to school. = He is too young to go to school.
=He is not old enough to go to school.
5. so that引导目的状语从句表示“为了，以便”，从句中常用can/could/will/should等情态动词。 They are hurrying so that they won’t miss the train. 引导结果状语从句时，意思为“因此，结果”。
He hurt his back, so that he won’t be able to play in the match.
相关例句：
1. She is so lovely a girl.
2. He has such a beautiful bike.
3. She is such a clever girl that everyone likes her. 4. There are so many people in the park.
5. This story is so interesting that I want to read it again. 6. He spoke so quickly that I couldn't follow him. 7. The box costs so little that I can afford it.

关于can't help do sth, can't help but do与can't help doing sth有很多同学搞不清楚，现作一个讲解，以期为莘莘学子拨开云雾，解除心中的疑惑。
①.can't help doing sth 禁不住做某事；情不自禁做某事. 如：其中，help 有“克制、抑制”的意思，意思是：不能克制住做某件事，即“情不自禁”。例如：

Hearing at this story, I can't help myself weeping. 听到这件事，我情不自禁地哭了。 She couldn’t help smiling. 她禁不住笑了起来。
She couldn’t help envying Helen. 她不由得不妒忌海伦。
We cannot help being impressed by their kindness. 我们不由得不被他们的善良感动。 ②.can't help to do sth 不能帮助做某事，换句话说就是和help to do sth的否定句. I can't help to do it. 我不能帮忙做这事。

He couldn't help to wash the clothes. 我不能帮忙洗衣服。
But one hundred and ninety is their final bid. I can not help it. 但190美元是他们的最终出价，我也不能做什么。(意为：没有办法)
③. can't help but do= have to do sth <省略to 的不定式> ，不得不做某事(其中，but 是介词，意为“除了这件事之外”)。
I could not but tell him about it. 我不得不告诉他这事。 She could not help but leave there. 她只好离开那里。

1) repair的对象范围很广，从房屋、道路、机器到日常生活必需品， 是使受到一定损失或失灵的东西恢复其形状或功能。 如:Who has repaired the broken leg of the table? 谁把桌子的断腿修好了？
Mary repaired the radio just for the fun of it. 玛丽修理收音机只是为了消遣。

She is mending her shoes. 她正在修理她的鞋子。
3) fix用于需要重新“调”物体的结构，把松散的部件固定结实，将分离的物体各部分装配起来。 用于美国口语中，与repair无多大区别。 Can you fix the broken chair? 你能修理那把坏了的椅子吗?
The workers are fixing the machine. 工人们在安装机器。 Have you had your watch fixed? 你已找人修你的表了吗？
