是的,"will"是情态动词。情态动词用于表达能力、可能性、许可或意愿等,而"will"用来表示将来的意愿或预测。
情态动词"will"在英语中扮演着重要的角色,其过去式"would"同样不可或缺。两者在功能和含义上有着密切的联系,了解它们的共性和差异对于掌握英语至关重要。
一、will与would的共性
"will"和"would"都可以用来表示时间、意愿、习惯和能力。
1. 表示将来时态,"will"用于构成一般将来时、将来进行时、将来完成时和将来完成进行时,而"would"则用于构成过去将来时等时态。例如,"By this time tomorrow, you will have reached New York."(到明天这个时候你就已经到纽约了)和"He said the weather would turn out fine the next day."(他说第二天天气会转好)。
2. 表示意愿,"will"用于现在或将来,"would"则用于过去。例如,"If you will help me now, I'll surely help you sooner or later."(要是你现在愿意帮我,我迟早也会帮你)和"However I tried, he just wouldn't listen."(不管我怎样努力,他就是不听)。
3. 表示习惯性或倾向性,"will"和"would"分别表示现在和过去的习惯。例如,"Sometimes he will tell lies."(有时候他也会说谎)和"Every day he would get up at six o'clock."(以前他每天早晨六点钟起床)。
4. 表示能力或功用,"will"和"would"同样用于现在和过去。例如,"This room will (=can) hold 60 people."(这个房间能容纳60人)和"He said the box wouldn't open."(他说那盒子打不开)。
二、请求与建议的表达
"Will / Won't you...?"和"Would / Wouldn't you...?"都可用于表达请求或建议,但"would"的使用使得语气更加委婉。例如,"Will / Would you please stand there?"(请你站在那里好吗?)和"Won't you come here?"(你过来好吗?)。
三、will与would的特殊用法
1. "will"的特殊用法包括在第二人称陈述句中表示建议或命令,意为"应该"或"必须"。例如,"You will act at once."(你应该马上行动)。
2. "would"的特殊用法包括:
(1)构成虚拟语气,如"If he were here, I would tell him the truth."(如果他在这里,我就会告诉他真相)和"Had you worked hard, you would have not failed the exam."(要是你努力学习了的话,你就不会考试不及格了)。
(2)用于构成"would like", "would rather", "would sooner"等表达,如"I'd rather not go there."(我宁愿不去那里)。
(3)"would have+过去分词"表示过去未曾实现的愿望,意为"本想……(却没有……)",例如,"I would have helped you, but I was too busy."(我本想帮你,可我太忙了)。
