短语 语法
填空题 when ____you buy the car ——In 1998
did
为什么不用were 要用did
并说明什么情况下改用are 什么情况下可以用do
我是这样理解的：
如果在一个句子里已经有一个实义动词了,那么助动词do（并根据人称和时态,加以变化）
如：when ____you buy the car ? ——In 1998
在这个句子当中已经有个实义动词buy了,就应该用助动词do.因为是过去时,所以改成did
如果一个句子里没有实义动词的话,就用be动词（并根据人称和时态,加以变化）如：Where _______ Tom ? 在这个句子没有实义动词,就应该用be动词
不知道这个方法对你适不适用
