that引导的定语从句
1 that引导定语从句，先行词不可能是整个句子。换句话说，定语从句修饰整个句子，一定是非限制性定语从句，关系代词只能用which，不能用that。2 当关系代词在定语从句中作主语，先行词为主句内容时，关系代词的数为单数。结合以上二点，你就会知道 that are similar to air pollution这个定语从句不可能是修饰全句的。that...

It is time+从句（虚拟语气为什么用was不用were）
根据传统语法，在过去式虚拟语气中，但主语为第一和第三人称单数时，非正式语体通常用was代替were。例如，If he were/was here now, I would tell him the truth. I wish he were/was here now. He treats me as if I were/was/is his son. 虚拟语气是早起英语的残留形式，英语发展的趋势是虚拟语气形式逐渐被陈述语气形...

可以说 prefer sb doing / prefer sb'd doing 吗
COCA语料库有这样一个例句： I think I would still prefer his being commemorated therein as the intended meaning. 一般而言，凡是可以后接动名词作宾语的动词，通常都可以后接动名词复合结构作宾语，唯一不同的是前者动名词的逻辑主语就是句子的主语（除非动词本身的语义排斥这种理解如suggest），后者动名词的逻辑主...

怎么区分as是连词还是介词
语法书通常是这么认为的，as/than后面只有一个名词或代词的时候，如果这个名词或代词可以扩展为一个分句，则as/than按照连词分析，as/than为比较分句，分句省略了有关成分。如果这个名词或代词无法扩展为一个分句，则as/than为介词，介词短语表示比较意义。例如，Tom is as tall as John. as John可以扩展为 as John is. 所...

现在分词的使用问题
I can't even afford the streetcar fare for going back home. for+动名词短语=介词短语，作fare的定语。I can't even afford the streetcar fare going back home. 现在分词短语作时间状语，分词的逻辑主语为句子的主语。= I can't even afford the streetcar fare when I go back home. ( So I have to walk home)下面为...
