正在学习被动语态,做题的时候有两个句子中的be动词的位置有点搞不懂。
教科书例句:How ofen are these rooms cleaned?
遇到的问题的句子:
1.A film studio is a place where films are made.
2.How many languages are spoken in Switzerland?
例句1和2中为什么不是A film studio is a place where are films made How many are languages spoken in Switzerland?呢,前面那个How ofen中be动词都提前了。
How often are these rooms cleaned?【答】这是特殊疑问句,如果疑问词(短语)不是主语,句型应该是“疑问词+一般疑问句语序”,How often 是疑问词(短语),被动语态的一般疑问句是把助动词be放在主语前面。
1.A film studio is a place where films are made. 【答】这里的 where films are made 是定语从句,如果它的谓语动词是被动语态,be不能放在主语前面。
2.How many languages are spoken in Switzerland? 【答】这是一个特殊疑问句,“How many languages ”是疑问词+其修饰的名词作主语,如果它的谓语动词是被动语态,be不能放在主语前面。
