Mr Smith ---me to buy several --eggs for dinner.A.asked ,dozen B suggested,dozens of Chad,dozen D

答案应该是：a
1.ask sb to do sth 让某人做某事
2.dozen一打,的具体用法：
dozen可用复数吗?dozen后要接of吗?你知道dozen的用法吗?请先看下面一道试题：
We already have _________ pencils,but we need two _________ pens.
A.dozen of,dozen B.dozens of,dozens C.dozens of,dozen D.dozens of,dozen of
关于dozen的复数是否加词尾-s的问题比较复杂,大致原则是：
1.当它与具体数字连用时,既不加复数词尾-s,也不后接介词of.尽管有的词书也有 two dozen of 这样的用例,但这已属过时用法,在考试中应避免,如1992年全国高考有一道单项选择题就认为two dozen of为错误选项：
Shortly after the accident,_________ police were sent to the spot to keep order.
A.dozens of B.dozens C.dozen of D.dozen [D]
2.当它不与具体数字连用,而是表示不确定的泛指数时,则不仅要加复数词尾-s,而且要后接介词 of,此时可将dozens of(许多,几十)视为习语.如：
I’ve been there dozens of times.我去过那儿几十次.
She’s got dozens of boy-friends.她的男朋友很多.
下面一例中的dozens加了复数词尾-s也属为似情况：
Pack them in dozens.按打装袋吧.
3.当与 a few,several 等数目不很具体的词连用时,加不加复数词尾-s均可,但需注意：不加复数词尾-s时,其后的介词of可以省略；加词尾-s时,其后介词 of不能省略.如：
several dozen (of) pencils=several dozens of pencils几打铅笔
注：英语较少使用many dozen的说法,要表示类似意思可用dozens of.
4.当它后面的名词受 the,these,those 等特指限定词修饰时,或其后的接的是us,them这样的人称代词时,则此时必须用介词 of.如：
two dozen of these eggs 两打这种鸡蛋
three dozen of them 它们中的3打
注：score,hundred,thousand,million等也具有以上类似用法.
这是我网上摘录下来的,很便于理解的.
