that不能省略 thatweareinvitedtoaconcertthiseveningisgoodnewstous 3 that引导宾语从句 常可省略 可接that从句作宾语的动词有 see say know imagine discover believe tell show think consider besure beafraid等 可以接复合宾语的动词有 think make

宾语从句是否定句时 只用if 不用whether iwonderifitdoesn train 2 用if会引起误解 就要用whether pleaseletmeknowwhetheryouwanttogo 此句如果把whether改成if 可作条件状语从句 因而产生歧义 3 宾语从句中的whether与ornot直接连用 就不能换成if idon
