以下是引用SunnyBean在2004-7-16 11:23:00的发言:石头哥哥,好久没有来CD了,刚发了个帖子就被你得找了,谢谢。看到你的提示,搜了一下大全,只有下面这一句的then 作连词是对的,其他的都是混淆选项。看来你所言极是,and then比较好些。 1. The owner of Steele’s Grocery in Osage, Ohio, saved $600 monthly on heat during the winter by putting all his refrigerator air compressors together in an insulated compartment, then installing two fans and a duct that carried waste heat from the compressors into the main part of the store.
(A) then installing two fans and a duct that carried
(B) then he installing two fans and a duct that carried
(C) then two fans were installed with a duct that carried
(D) installing two fans, and then carrying through a duct (E) installing two fans, and a duct carrying 答案是A.
我认为这里then还是adv.修饰installing,与putting一样都是by的表动作的动名词宾语,then并非作为连词,因为后面没有谓语只是一个动名词短语。 |
