四、 关于不定式符号的几个问题
A.不带to的不定式 1.在口语中,动词原形come和 go后可接不带to的不定式。 Go tell her. 去告诉她吧。 Come have a glass. 来喝一杯。 2.在why引起的一些问句中,疑问词直接跟动词原形或not+动词原形。 Why make so much noise 为什么发出这么大的噪音? Why not join us 为什么不加入我们?
3.在had better, had best, would rather, would rather...than, would sooner, would sooner...than, cannot but, cannot choose but, cannot help but等结构后直接跟动词原形或not +动词原形。 You'd better listen to your teacher's opinion. 你最好听一听老师的意见。 We had best call for the doctor at once. 我们最好马上就请医生来。 She can't do anything but ask silly questions. 她一直在问一些愚蠢的问题。 Rather than ride on a crowded bus, he always prefers to ride a bicycle. 他宁愿骑自行车,也不愿挤公共汽车。 He cannot but move to another street, because his building has to be pulled down soon. 他不得不搬到另一条街上去,因为他住的大楼很快就要被推倒。 We cannot help but admire his courage. 我们情不自禁地钦佩他的勇气。
4.如不定式前有行为动词do,那么在表语从句中的不定式和介词except或but之后的不定式可不带to。 The only thing I could do was go home. 我能做的唯一一件事就是回家。 They could do nothing but wait for the doctor to come. 他们只能等待医生的到来。
