Question

20．课堂上要尽可能多说英语，这样你的口语就会提高．
Speak English as much as possible in class．，and then your spoken English will improve．

Answer 1

分析 Speak English as much as possible in class．

解答 答案：Speak English as much as possible in class．结合句子的结构，这里是祈使句+and+陈述句，祈使句是以动词原形开头，表示说英语用speak English，English不可数，故尽可能多的as much as possible，课堂上in class，故答案是Speak English as much as possible in class．

点评 祈使句，+and+陈述句：在这里祈使句相当于if 引导的条件状语从句（但此时去掉and）．
Give blood （ if you can ）and many lives will be saved．
还可以用简短的形式表示，即省略动词．
Give me one more hour，and I'll get the work finished．（祈使句）
═One more hour，and I'll get the work finished．（名词短语）
═If you give me one more hour，I'll get the work finished．（if条件句）
═If I am given one more hour，I'll get the work finished．
