1 I am not sure what I should choose.这里面的sure是表语,后面的what从句是充当什么成分?表语从句?(一个句子中可以有两个表语?)宾语从句?(主句是系表结构,可以有宾语吗?)
2 我看到介词口诀中最后一句是"修饰动形要记牢",我想问介词可以修饰动词吗?若可以请举例,小弟不甚感激!

第一句话的句法不用抠那么细了知道后面是个从句就行了
第二个可以给你举个例子
He swam across the river.他游过了这条河.
swam across 中的 across 就是用来修饰动词 swam 的

am not sure where I could have left it中where引导的到底是状语从句还是表语从句 I am sure that...的句子成分?sure是表语,that后面应该不能加宾语或补语吧? I am not sure what your talking I am not sure what else to 关于 I am not sure后的宾语从句 I'm not sure what I should do next 求这句话的同义句中学英语语法问题I am not sure what is he talking about.I am not sure I am sure I will pass the exam.是宾语从句,那么怎么区分形容词的宾语从句和表语从句呢? i'm not sure when to go tomorrow.是表语从句还是宾语从句? I am not sure what to except同义句 i am not sure what have to do today. I am not sure what to do next 什么意思
