be动词的用法总结及练习题(3)
be动词的用法：注意事项
英语句子中，为了表达时态或被动语态的需要，常常会出现几个助动词连在一块儿使用。也就是说，助动词be会和其它学习啦在线学习网助动词一起使用。这时候，整个句子的一般疑问句和否定句，就不一定是对be 进行变化了，而是以第一个助动词为主进行变化。即哪个助动词在先，就以它为主进行变化。例如：
[肯定句] All the wonderful birds can be found in our Bird Park. (助动词有两个：can be )
[疑问句] Can all the wonderful birds be found in our Bird Park? (移第一个can)
[否定句] All the wonderful birds can not be found in our Bird Park. (在第一个can 后加not)
