1.I am afraid that the grandparents have some ---the naughty

1。I am afraid that the grandparents have some ___the naughty grandson。A trouble with B trouble in C troubles in D troubles with 答案是A,记得与trouble搭配的是in,还有不是有some嘛,应该用复数啊!为什么选A啊?回答：have trouble in doing sth;have troule with sth。trouble是不可数名词,当然可以用some了,再说了some和any都可表示任何一个的意思,他们与单数可数名词也是可以连用的。2。Her tactless remarks just added fuel to fire and difficulty to ____peace with others。A making B make 答案是A,为什么啊?回答：add 。。。to 。。。是不定句型。其中的to是介词后接名词或动名词。3。She pretended ____the truth already,but it caused unexpected trouble for herself。A to had known B to have known 答案是B。后面是caused,不是应该用过去完成时嘛!回答：pretend to do sth是句型,其后面的不定式的时态要根据不定式与谓语动词发生的先后关系来决定,这里的意思是“他假装知道”,这个不定式的动作显然发生在pretend之前所以要用完成时to have doen的形式。没有to had known这样的形式。4。Ido not remember how many years ago_____I last showed you around the factory。A it was that B it was when 答案是A。为什么啊?好像是强调句,可是去掉it was that有点不同耶!回答：是强调句,去掉以后也成立啊。how many years ago I last showed you around the factory,只是你要知道这是宾语从句要用正常语序。不可以说 I do not remember how many years ago did I last show you around the factory 5,The director gave me a better offer than _____ A that of Dick’s B Dick’s C he gave Dick 答案是C,为什么啊?AB错哪里了?回答：应该选C。这其实是一个省略句。补充完整应该是：The director gave me a better offer than he gave Dick an offer。也就是说这是offer 与offer比较。而这两个offer都是the director提供的。在A、B两项里都用了dick's（迪克的）,迪克的什么呢?是迪克提供的offer?那又是给谁提供的呢?意思很不清楚。造成比较对象混乱。
