(1) We've talked a lot _____ cars. What about trains?
A. of B. with C. about D. in
解析：由于受 a lot of 这一常用结构的影响，许多同学毫不犹豫地选了A，但是错了。原因是：若选 of，a lot of cars即为动词 talk 的宾语，但事实上，动词 talk 是不及物动词。正确答案是C，句中的a lot是修饰动词 talked的状语，talk about才是一个动词短语。 全句意为"我们对汽车已谈了不少，现在谈谈火车怎么样?"
(2) We all regarded the poor old man ____sympathy。
A. as B. with C. of D. by
解析：许多同学一看到句中的 regard 和选项中的 as，马上就联想到 regard ... as.。.(把....。.看作....。.)这一搭配，从而断定此题应选A。错了，原因是将此搭配套入原句，句子意思不通。正确答案是B，句意为"我们大家都很同情这位老人"。
3. 适当转换句式
有时将题干的句式转换成自己更熟悉的句式，就很容易选出正确答案。比如将疑问句、强调句、感叹句或倒装句改为陈述句，将被动句改为主动句，无序句调整为正常句。例如：
-Mr. Wang, whom would you rather _____ the important meeting?
-Tom。
A. have attend B. have attended
C. having attend D. have to attend
解析： 若将疑问句改为陈述句，就是I would rather have Tom attend the important meeting. 其中would rather后必须接动词原形，have sb. dosth。是"要某人做某事"。所以选A。
