Should - Meaning, pronunciation, collocation and usage 英漢雙解 | Mr. Ng 線上詞典

Should is usually followed by an infinitive without ‘to': should 通常后接不带to的不定式 : You should eat more fresh fruit. 你应该多吃些新鲜水果。 Sometimes should is used without a following infinitive: 有时should 后面不接不定式: I don't always do everything I should. 我并非总是做所有该做的事情。

Should does not change its form, so the third person singular form does not end in ‘-s': should没有词形变化，故其第三人称单数形式也不加-s: She should see a doctor about that cough. 她应该去找医生看看她那咳嗽。

Questions and negatives are formed without ‘do': 构成疑问句和否定句时不用do: Should we come back later? 我们等会儿回来吗？ You should not bring up embarrassing topics. 你不应该提起令人尴尬的话题。

The negative form should not is often shortened in conversation or informal writing to shouldn't: 在对话或非正式文体中，其否定形式should not常缩略为shouldn’t : Those kids shouldn't be in there. 那些孩子不应该在那里。

Should is often used in question tags: should常用于附加问句中: We should leave a tip, shouldn't we? 我们应该给小费，是不是？

Should has no participles and no infinitive form.

There is no past tense, but should have followed by a past participle can be used for referring to actions that did not happen or for actions that have probably happened: should没有分词和不定式形式，也没有过去式，但should have后接过去分词可以用来表示没有发生或很可能已经发生的动作: I should have brought an umbrella (=I did not bring one). 我本来应该带把伞的。 The meeting should have finished by now (=it is likely it has ended). 会议现在应该已经结束了。

When indirect speech is introduced by a verb in the past tense, should can be used as the past tense of shall: 在由动词过去式引导的间接引语中， should 可以用作shall的过去式: I explained that I should be too busy to see them the following day. 我解释说我第二天会很忙，没有时间见他们。
