where= at/in/to which. 当先行词为room时,我们说 go to the room, 不能说 go in the room或者 go at the room. 但我们可以说go there. 所以这里要用where,而不能用in which. 如果介词换成to, 即 to which, 则是可以的。或者原句中去掉go, That is the meeting-room ______ they used to have meeting. 此时用...

Sb is said/believed/known等后接动词必须用不定式,不能改用现在分词。当不定式的动作与谓语动作具有同时性时,则不定式需要用进行体。Huddleston著《剑桥英语语法》将这种结构称为提升主语(raised subject),即一个分句的主语被提升到高一级的分句中作主语。原句是下面这样的。It is said/believed/known that sb does/...

He drove faster than was wise.你在哪本书上看到说也可看作由as/than充当了比较分句的主语。这个句子我用Huddleston《剑桥语法》的观点解释如下:than为连词不作分句成分。所以比较分句只有系表结构而缺失主语。一个比较分句省略主语而保留谓语动词只可能是以下二种情况之一:1 比较分句的主语为比较对应项。2 比较分句的...

can表示推测不能用于肯定句。但非推测的can可以表示客观条件的允许或理论上的肯定性,而不是主观推测。火星上并没有理论上支持的能让生命存在的可能性。所以无论是主观推测还是客观条件许可,在这里都不能用can.

答疑网这类问题和解答很多的。你可以查阅。简单回答如下:如果把as和than分析为连词,不作从句成分,则比较分句必然是一个结构不完整的分句,必须留出一个空位。该空位就是主句比较项在从句的对应项。即主句比较项的对应项必须在从句中省略,不可出现。你的句子简化如下:The diet has at least 30 percent fewer calo...

以下三个句子都是正确的。比较分句省略了that从句(that从句结构可从主句获知)。1, The boy is more clever than we expected.= The boy is more clever than we expected that he would be.2, The boy is more clever than was expected.= The boy is more clever than it was expected that he would be,3, The boy is m...
