            將來(lái)完成時(shí)表示到將來(lái)某一時(shí)刻已完成的動(dòng)作或狀態(tài)。將來(lái)完成時(shí)由shall/will have加過(guò)去分詞構(gòu)成。

            1.1 將來(lái)完成時(shí)的構(gòu)成
            肯定句:主語(yǔ) + shall/will have + 過(guò)去分詞...
            否定句:主語(yǔ) + shall/will + not + have + 過(guò)去分詞...
            疑問(wèn)句:Shall/Will + 主語(yǔ) + have + 過(guò)去分詞...?
            疑問(wèn)代詞/疑問(wèn)副詞 + shall/will + 主語(yǔ) + have + 過(guò)去分詞...?

            將來(lái)完成時(shí)

            1.2 將來(lái)完成時(shí)的肯定句
            句型:主語(yǔ) + shall/will have + 過(guò)去分詞...
            將來(lái)完成時(shí)的肯定句由“助動(dòng)詞shall/will have + 過(guò)去分詞...”構(gòu)成:

            I shall have done it by next week.我將于下周前做完它。
            I shall have completed my report by Friday.到星期五我就會(huì)完成我的報(bào)告。
            The snow will have disappeared before the end of February.積雪將于2月底之前融化。

            1.3 將來(lái)完成時(shí)的否定句
            句型:主語(yǔ) + shall/will + not + have + 過(guò)去分詞...
            將來(lái)完成時(shí)的否定句是在助動(dòng)詞shall/will后加not,之后是“have + 過(guò)去分詞”:

            We have worked together for several years. She won't have forgot-ten me.我們?cè)谝黄鸸ぷ髁藥啄?,她大概不?huì)不記得我。

            1.4 將來(lái)完成時(shí)的一般疑問(wèn)句
            句型: Shall/Will + 主語(yǔ) + have + 過(guò)去分詞...?
            回答方式:Yes,主語(yǔ) + shall/will.
            No,主語(yǔ) + shall/will + not.
            將來(lái)完成時(shí)的疑問(wèn)句是將助動(dòng)詞shall/will置于主語(yǔ)之前(大寫(xiě)shall/will的第一個(gè)字母),在句尾加問(wèn)號(hào);這種語(yǔ)序是倒裝語(yǔ)序:

            Will you have done it all by 10:30pm? —No,I won't have done it by then.你能在晚10點(diǎn)半之前把它全部做完嗎? ——不,我那時(shí)還做不完。
            Will you have finished reading the book by Friday? —Yes,I'll have finished reading the book by Tuesday.你會(huì)在星期五之前看完這本書(shū)嗎? ——是,我最遲在星期二就看完這本書(shū)了。

            1.5 將來(lái)完成時(shí)的特殊疑問(wèn)句
            句型:疑問(wèn)代詞/疑問(wèn)副詞 + shall/will + 主語(yǔ) + have + 過(guò)去分詞...?
            將來(lái)完成時(shí)的特殊疑問(wèn)句是將疑問(wèn)代詞/疑問(wèn)副詞置于助動(dòng)詞shall/will之前(shall/will的第一個(gè)字母無(wú)需大寫(xiě)),和一般疑問(wèn)句差不多;這種語(yǔ)序是倒裝語(yǔ)序。就主語(yǔ)提問(wèn)時(shí),將疑問(wèn)代詞或帶有疑問(wèn)限定詞的名詞詞組置于助動(dòng)詞shall/will之前,在句尾加問(wèn)號(hào);這種語(yǔ)序是陳述句語(yǔ)序:

            How many words shall we have learned by the end of the term? 到本學(xué)期末我們可能學(xué)了多少詞匯?

            1.表示將來(lái)某一時(shí)刻前業(yè)已完成的動(dòng)作

            一般都要用一個(gè)表示將來(lái)時(shí)間的狀語(yǔ),如由by(截至),before(在……以前)引導(dǎo)的介詞詞組或由when(在……時(shí)候),before(在……以前)等連詞引導(dǎo)的狀語(yǔ)從句:
