Question

关于as if的两道选择题
1 The teacher paused as if ____ his students to ask questions on the point he had just said.
A.expecting B.to expect
2 The old man stopped as if____wheather he was in the right direction.
A.to see B. seeing
这两道题到底有什么区别是语法上的还是as if的语境的
为什么一个是ing 另一个是不定式?

Answer 1

1.A ,这是一个现在分词短语用作伴随状语.写成完整句子应该是：The teacher paused as if he were expecting his students to ask questions on the point he had just said.
2.A,这是个不定式做目的状语.
从这两个例子可以看出选择非谓语动词的时候,一定要考虑句子的意义和语法的要求,不要只考虑一个.
