Would is usually followed by an infinitive without ‘to': would 通常后接不带to 的不定式: A picnic would be nice. 去野餐挺不错的。 Sometimes it is used without a following infinitive: 有时后面不接不定式: They didn't do as much as they said they would. 他们做的没有他们说的那么多。
In conversation and informal writing, would is often shortened to 'd: 在谈话和非正式书面语中, would 常简写为 ’d: I thought you'd like a drink before dinner. 我原以为你吃饭前要喝点酒。
Would does not change its form, so the third person singular form does not end in ‘-s': would没有词形变化,第三人称单数后面不加 -s: As a child, she would often run away from home. 小时候她就常常离家出走。
Questions and negatives are formed without ‘do': 构成疑问句和否定句时不加do: Would you like a cup of coffee? 你想喝杯咖啡吗? He would not tell us his secret. 他不想告诉我们他的秘密。
The negative form would not is often shortened in conversation or informal writing to wouldn't: 在谈话或非正式书面语中否定形式would not 常常简写为wouldn’t: I wouldn't want to have your job. 我不想干你的工作。
Would is often used in question tags: 常用于附加疑问语中: You wouldn't lie to me, would you? 你不会对我撒谎,是不是?
Would has no tenses, no participles, and no infinitive form.
There is no past tense, but would have followed by a past participle can be used for talking about actions that did not happen: would 没有时态、分词和不定式形式。虽然没有过去时态,但是would have 可后接过去分词,用于谈论没有发生的动作: She would have bought the house if she had been able to afford it (=she did not buy it). 如果她能支付得起,她就买下那栋房子了。
In some cases would can be used as the past tense of will, for example in indirect speech introduced by a verb in the past tense: 在某些情况下,would 可以用作will 的过去式,如在由过去时态的动词引导的间接引语中: I promised that I would visit her the next day. 我答应第二天去拜访她。
