be going to 的用法

be going to + 動(dòng)詞原形——表示將來(lái)的打算、計(jì)劃或安排。常與表示將來(lái)的tomorrow, next year等時(shí)間狀語(yǔ)或when 引導(dǎo)的時(shí)間狀語(yǔ)從句連用。各種句式變換都借助be 動(dòng)詞完成，be隨主語(yǔ)有am, is, are 的變換，going to 后接動(dòng)詞原形。

肯定句： 主語(yǔ) + be going to + 動(dòng)詞原形 + 其他。 eg: ? He is going to take the bus there.

否定句： 主語(yǔ) + be not going to + 動(dòng)詞原形 + 其他 eg:I’m not going to see my friends this weekend.

be going to 與 will 的區(qū)別

① 對(duì)未來(lái)事情的預(yù)測(cè)用“ will + 動(dòng)詞原形”表達(dá)，will 沒(méi)有人稱和數(shù)的變化，變否定句要在will 后面加not, 也可用will 后面加 not,或者縮略式won’t, 變一般疑問(wèn)句將will 提至 句首。Will planes be large in the future? ?Yes, they will. / ?No, they won’t.

②will 常表示說(shuō)話人相信或希望要發(fā)生的事情，而be going to 指某事肯定發(fā)生，常表示事情很快就要發(fā)生。I believe Lucy will be a great doctor.

③ 陳述將來(lái)的某個(gè)事實(shí)用will. I will ten years old next year.

④表示現(xiàn)在巨大將來(lái)要做的事情用 will.I’m tired I will go to bed.?

⑤ 表示意愿用will.I’ll tell you the truth.

⑥ 表示計(jì)劃、打算要做的事情用 be going to, 而不用 will.
