用不定式代替从句部分,例：i don't know what to do.我觉得从什么解释都解释不通啊,怎么能这样用呢?

用不定式代替从句部分,例：i don't know what to do.我觉得从什么解释都解释不通啊,怎么能这样用呢? I don’t think it will rain .这句话中哪个部分是主句,哪部分是从句. 用不定式连接下列句子I'm ashamed.I must say I don't know much about the country. I don't know when l shall start the work.(用动词不定式改写）I don't know when _____ _____ the work. i don't want to say anything that might hurt youi don't want to say anything to hurt you 第一个是定语从句 一个不定式做定语两句话是一个意思吧? 关于think的反义疑问句I think I am right,don’t I?为什么要用don’t?不是说think、belive、expect、suppose、imagine等词引导的定语从句,疑问部分与宾语从句相对应构成反义疑问句么?I think I am right中I am ri I don't know what to say at the meeting (用John代替句子主语) 第一题怎么解释,第三题用不定式代替的定语从句是不是结构不完整? I will never forget the school.I have studied there for 3 years .（改为定语从句）I hope that I can pass the Mid-term Exam.(用不定式改写)I'd like to go to NewYork.I don't know the language there.(改为复合句）He said he knew I really don‘t know which one to buy 为什么用动词不定式有两个动词吗如果有请指出 I'm new here.-Don't worry.I'll do what I can to help you.中what .you是宾语从句吗?或是在这里to help是动词不定式,是宾补,请问怎么样才算是宾补呢? what to say 是固定用法么?请问下:I don't know what to say.这句话..know后面 宾语从句里面的主语呢?另外就是用what say不可以么?有从句的情况下,是可以出现动词原形的啊,怎么成了to say不定式了? I haven't seen her since yesterday .划线部分since 用a few mintes ago 代替 宾语从句 which one 和what 后跟不定式的区别I've never seen so many beautiful pictures.I don't know _____.A.which one to takeB.what to take 哪个正确, 什么时候宾语从句用陈述句语序什么时候不用 I don't know what's your hobbies I don't think that+从句（造句）注中文 afraid i don't understand请问这句是从句吗? I don't mind ____(work)over time.I wouldn‘t consider______(make)these changes.何时用动词不定式什么时候用ing啊（这个ing是指像remember后面可以加ing也可以加动词不定式）
