高中英语否定句的类型:
1. 一般否定句的构成方式是在功能词(即系动词,助动词或情态动词)后加否定词not等形式。常译为"不是"或"非"。
—It's a long time since I saw my sister.
—Why not visit her this weekend?(2007,全国I,24)
2 部分否定句的构成方式是由含有以下表全部概念的词all/ everything/ always/ entirely/ altogether/ everywhere/ everybody/ both 等加否定词not构成。注意:在否定句中只要有以上的词,即可视为部分否定,而不管否定词在句中的位置。常译为"不是一切/不总是……都……"。(刘锐诚,2006)
I agree with most of what you said, but I don't agree with everything .(1997,全国,14)
