4、row , turn ,go ,come, run,fall5: prove, turn out 连接词：that / whether /as if /as though (if不引导表语从句)连接代词：who / whom / whose / which / what 连接副词：when / where / why / how / because表语从句1. that1) that 在从句中不担任句子成分，无实际意义，一般不能省略2)在表“建议，劝说，命令”的名词idea, suggestion, request, proposal 等后面的表从句中，谓语动词用“should + 动词原形”

5、，should可省略My opinion is that its getting better and better.My suggesstion is that we (should) start early tomorrow.2.whether在表语从句中表 “是否”,但不充当句子的成分。if “不能”引导表语从句。如:What the doctor really doubts is whether my mother will recover from the serious disease soon.The question is whether it is worth doing.3

6、.as if, as though 引导的表语从句1)as if/though引导的表语从句常置于连系动词look, seem, sound, be, become等后面，常用虚拟语气，表示不存在的动作或状态。e.g. It sounds as if/though somebody was knocking at the door.2) 主语+连系动词（look/seem/appear）+that/as if从句*as if/as though引导的表语从句如果是事实，就用陈述语气；如果与事实不符，就用虚拟语气(主句一般现在时,从句就用过去式，be的话变成were。主句是过去式，从句用过去完成
