Question

19．到本學期結束的時候，我們將已經學完了兩冊課本．（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"我們將已經學完了兩冊課本"可知，句子的主句部分需要使用將來完成時，而從句中使用一般現(xiàn)在時表示將來時．
by the time引導時間狀語從句時的用法有兩種：
1．表示將來的時間．
主句用將來完成時，而從句用一般現(xiàn)在時來表示將來的動作．
如：I will have finishied the work by the time my father comes back．
2．表示過去的時間．
主句用過去完成時，而從句用一般過去時．
如：He had built a lab for himself by the time he was 12 years old．

點評 翻譯題在解題時首先要確定好句子的時態(tài)，然后要把握好短語表達，最后要注意句子結構．
