有既可以用what,又可以用that的宾语从句吗?举个例子

有既可以用what,又可以用that的宾语从句吗?举个例子 英语中where~that,who~that,when~while,以及which的用法区别有时候that可以通用 有时候有只可以用that 有时候又不可以用that 谁给我详解下 引导词 既可以做前面一个句子的宾语,又可以做后一个句子的主语的是什么,that,还是what 关于what引导的宾语从句,怎么理解what引导的宾语从句?也就是与that which引导的有什么不同.这个句子,we arrived at what was calledXXX.为什么要用what?其他的为什么不可以 What colour is your watch?可以用 What colour your watch?吗?What colour is your watch?也可以用 What colour your watch?吗?少了一个is 和没有is有什么区别呢?What make is that? 也可以用What is that make?吗 为什么呢?What make 冠词“类别”的区别a/an/the+单数可数名词 这是可以互换吗?但又有什么差别?例：what's this in English?----It's (a) ruler 这句话可以用the+单数可数名词吗?It's said that (the) umbrella was invented over four thousa 冠词“类别”的表示方法a/an/the+单数可数名词 这是可以互换吗?但又有什么差别?例：what's this in English?----It's (a) ruler 这句话可以用the+单数可数名词吗?It's said that (the) umbrella was invented over four one half of the station did not know what the other half was doing.这里的what 可以省略吗?可以用that代替吗? because of what I learned from it.(what 为什么不可以用that 英语 It is demand that influences supply 可以用what代替that吗? The mother made a promise that pleased her child可以用what 代替that吗? How do you find the work what/that I do? 这里 what和that是不是都可以用? 英语语法关于代词我搞不清楚...比如什么句式使用what 什么时候不能...什么时候用it...又不能用that.貌似有的情况可以用one.晕了. remember用法I do not remember it ever being so hot.这个句子用的remmember it doing?有这种用法?即使that可以省，is又怎么可以省？为什么“可以不用is”？ what's that?____is a pencil我写的是that,但老师说事一定要用it.为什么?that也可以啊我觉得 what 在名词性从句中的用法是什么 ,我总是和that有所混淆,状语从句和定语从句中有可以用what 混有水蒸气的下列气体中,既可以用农硫酸干燥,又可以用苛性钠干燥的是 What are those?可以用Those are……回答吗?还有What is that?可以用That is……回答吗?
