Question

19．到本學(xué)期結(jié)束的時(shí)候，我們將已經(jīng)學(xué)完了兩冊(cè)課本．（by the．time---）We will have finished two books by the time this term is over/ends．．

Answer 1

分析 We will have finished two books by the time this term is over/ends．

解答 We will have finished two books by the time this term is over/ends．
根據(jù)句意"我們將已經(jīng)學(xué)完了兩冊(cè)課本"可知，句子的主句部分需要使用將來(lái)完成時(shí)，而從句中使用一般現(xiàn)在時(shí)表示將來(lái)時(shí)．
by the time引導(dǎo)時(shí)間狀語(yǔ)從句時(shí)的用法有兩種：
1．表示將來(lái)的時(shí)間．
主句用將來(lái)完成時(shí)，而從句用一般現(xiàn)在時(shí)來(lái)表示將來(lái)的動(dòng)作．
如：I will have finishied the work by the time my father comes back．
2．表示過(guò)去的時(shí)間．
主句用過(guò)去完成時(shí)，而從句用一般過(guò)去時(shí)．
如：He had built a lab for himself by the time he was 12 years old．

點(diǎn)評(píng) 翻譯題在解題時(shí)首先要確定好句子的時(shí)態(tài)，然后要把握好短語(yǔ)表達(dá)，最后要注意句子結(jié)構(gòu)．
