在论述题中，问题大多具有委婉性，尤其是历年真题部分，在给考生较大发挥空间的同时也大大增加了考试难度。
考生要认真阅读题目中提供的有限材料，明确考察要点，最大限度的挖掘材料中的有效信息，建议考生答题时用笔将重点勾画出来，方便反复细读。
只有经过仔细推敲，揣摩命题老师的意图，积极联想知识点，分析答题角度，才能够将考点锁定，明确题意。

试题注重情景的设置，需要利用特点语言环境中上下文的联系，正确分析结构，理解句意是做此类题目的关键。
1.it/that/one用法区别〔it主要指代前面提到的同一物；one用来指代前面出现的单数名词，相当于a/an+单数名词，表泛指概念，往往是同类而同一物；that用来替代前面出现的特指的单数可数名词或特指的不可数名词，相当于the＋单数/不可数名词〕2.it用在某些动词后,如:enjoy,like,,dislike,resent,hate,don’tmind,befondof,feellike,seeto之后,即这些动词后面的宾语从句前要加it代替其后的从句3.用于强调句或固定句型〔itis/was…when/since/before…〕中.4.作形式宾语或形式主语〔主要代替ving,todo或从句〕5.考查it构成的习语，it也常表示抽象的情况,属于虚指.如:Takeiteasy.【知识要点】It的用法〔一〕作人称代词1、it代替前面〔或后面〕的单数名词或分句等所表示的事物。
e.g.Youcannoteatyourcakebuthaveit.〔it代替前面的cake〕Althoughwecannotseeit,thereisairallaroundus.〔it代替后面的air〕Theysayhehaslefttown,butIdon’tbelieveit.〔it代替前面They…town分句中的情况〕2、代替有生命但不能或不必分阴阳性的东西〔包括婴儿〕。

用法区别”足以做动词1. 【答案】 D 【解析】句意：她是外国人的事实使得她在哪个国家很难找到工作。
考查 it 的用法。
句中 for her to get a job in that country合结构做made 的宾语，difficult 是宾语补足语，此处要用有这种用法。
2. 【答案】 D 【解析】考察 it 的用法。
句意为：“医生认为对你来说休个假很好。
后接的是一个宾语从句，这个宾语从句里含到了结构 it is good for sb to do sth 在这里 it 作的是形式宾语，猪油 it 可以作形式主语或者形式宾语。
3. 【答案】 B 。
【解析】 意思是： 我喜欢这个前面有一个美丽花园的房子， 下来。
第一句话中的 特指。
该题容易误选 【考点定位】 it/that/one 4. 【答案】 D【解析】句中 “not how much you read but what you read 所有选 D 使之构成强调句型。
【考点定位】本题考查强调句型和名词性从句。
5. 【答案】 C【解析】本题较难，但根据句意 “作一名家长并不是很容易，并且作为一名有着特殊需要的 孩子家长， 由于当这种特殊需要的孩子家长而带来额外的压力 ”。
分清指代， it 指代上 文 being the parent of a child with special needs内容， carry 的宾语为 extrastress,with it 表示原因，防止误选 C. ，由此可知选 A 【考点定位】考查代词 it 用法。
6. 【答案】 D.【解析】本题考查 it 作形式主语，代替 that improvements in health care will lead toa stronger, more prosperous economy ，而其他选项均不可以充当形式主语。
7. 【答案】 C【解析】此题考查 it 的特殊用法。
it 可用于某些动词之后，无确切的含义，构成习语。
此 处 If Ican help it 意为“如果我有办法的话 ”。
有时我们也可以说成 It can't be helped 或 There is no help for it。
表示 “实在没有办法 ”。
常见口语中带 it 的惯用语：（you've/I 've ）got it 懂了，明白了 ;forget it 算了吧，别提了，休想，不可能 ;Don 't mention it （别人道谢时回答）不客气 ;Take it easy 别急，慢慢来 ; “make it + 时 间"把… 定在（某时）；lt/all depe nds 那要看情况而定；It ' hard to say 情况很难说 ; It comes to nothing 没什么结果。
8. 【答案】 B解析】考查代词。
第一空不定代词 it 指代前面的 postcard ；第二空 to 后的宾语应为反 身代词 herself.9. 【答案】 C【解析】考查 it 作形式主语，代指 watching myself on TV ，其他选项均不可以充当形式宾语。
10【答案】 D【解析】考查it作形式主语，句中it充当形式主语，真正的主语是the way，其后又有定语从句 he keeps changing his mind 修饰。
【 it 用法答案与解析】1. 选 C。
one 指 a coat 。
比较： it = the + 名词， one = a+ 名词，换句话说， it 是特指的，而 one 则是泛指的。
