will he go to * by plane or by train?改为同义句
问题描述：
will he go to * by plane or by train?改为同义句
will he fly to * or (take/taking) a train?
who is the first person that (eat/eating) cakes?
答
will he fly to * or take a train?
or连接的前后要一致,句前有will所以前面动词用的fly原型,后面必然要用take原形了.
who is the first person that eating cakes?
用eating,that后面是定语,-------谁是第一个人；应该是：谁是第一个吃蛋糕的人?而定语是修饰前面的,所以用ing.
