Grammar Point modal verbsmodal verbs- The modal verbs are can, could, may, might, must, ought to, shall, should, will and would. Dare, need, have to and used to also share some of the features of modal verbs.
can、could、may、might、must、ought to、shall、should、will 和 would 均爲情態動詞。dare、need、have to 和 used to 亦具有情態動詞的某些特性。 - Modal verbs have only one form. They have no -ing or -ed forms and do not add -s to the 3rd person singular form:
情態動詞只有一種形式，沒有 -ing 或 -ed 形式，第三人稱單數也不加 -s： He can speak three languages. 他會說三種語言。 She will try and visit tomorrow. 她明天將設法去參觀。
- Modal verbs are followed by the infinitive of another verb without to. The exceptions are ought to, have to and used to:
情態動詞後跟不帶 to 的動詞不定式，但 ought to、have to 和 used to 例外： You must find a job. 你必須找到一份工作。 You ought to stop smoking. 你應當戒煙。 I used to smoke but I gave up two years ago. 我過去抽煙，但兩年前就戒了。
- Questions are formed without do/does in the present, or did in the past:
疑問句現在時不用 do/does，過去時不用 did： Can I invite Mary? 我可以邀請瑪麗嗎？ Should I have invited Mary? 我本該邀請瑪麗嗎？
- Negative sentences are formed with not or the short form -n’t and do not use do/does or did.
否定句用 not 或簡約式 -n't，不用 do/does 或 did。
情態動詞的不同用法可參考本詞典裏各情態動詞詞條。 - In modern English, the traditional difference between should and would in reported sentences, conditions, requests, etc. has disappeared and should is not used very much at all. In spoken English the short form ’d is usually used:
