　　译林牛津版高二英语语法考点(2)：状语从句的省略

　　省略（Ellipsis）是为了避免重复，突出新信息并使上下文紧密连接的一种手段。省略在语言中，尤其在对话中，是一种十分普遍的现象。在近几年的高考试题中，省略现象也尤为常见。

　　〖考点二〗状语从句的省略

　　03.The research is so designed that once _____ nothing can be done to change it.

　　A. beginsB. having begun C. beginning D. begun

　　04. Though ______ money, his parents managed to send him to university.

　　A. lacked B. lacking of C. lacking D. lacked in

　　当见到when（或if, where, wherever, whenever, as soon as, than等）+ possible / necessary时，可理解中间省略了it is / was.

　　When (it is) necessary, you can help us to do something.

　　Answer these questions, if (it is) possible without referring to the book.

　　Ill inform you by e-mail when (it is) necessary.

　　He looked as if (he were) afraid of nothing.

　　【注意】由if构成的省略结构，已属于固定短语。如：if any, if necessary, if possible, if not, if so等。如：

　　If necessary, ring me at home.

　　He may be busy. If so, Ill call later. If not, can I see him now.

　　用so, not, neither, nor或其它手段来省略上文或问句中的一部分或整个句义。

　　1、so与 not常可用来替代前面说的话，so表示肯定的替代，not表示否定的替代，即+谓语+not或not+谓语+so。So还可以和even, still, if, absolutely等连用，not可与 if, perhaps, of course, better why (not)等连用，构成缩略句。

　　-Can Emily do this work?埃米莉能做这件工作吗？

　　-I think so.我想她行。

　　-I think not.（或I dont think so.）我想她不行。

　　-Did you know anything about it?这件事你以前知道吗？

　　-Not until you told me.直到你告诉了我，我才知道。

　　2、So+谓语+主语表示前面的肯定情况也适合于后者；So+主语+谓语强调主语的情况的确如此；Neither/Nor +谓语+主语表示前面的否定情况也适合于后者。

　　-He did well in this examination.-So he did.

　　-She has been to the Great Wall.-So have I.

　　If you dont go to the cinema, neither will I.
