Question

20．課堂上要盡可能多說英語，這樣你的口語就會提高．
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．結合句子的結構，這里是祈使句+and+陳述句，祈使句是以動詞原形開頭，表示說英語用speak English，English不可數，故盡可能多的as much as possible，課堂上in class，故答案是Speak English as much as possible in class．

點評 祈使句，+and+陳述句：在這里祈使句相當于if 引導的條件狀語從句（但此時去掉and）．
Give blood （ if you can ）and many lives will be saved．
還可以用簡短的形式表示，即省略動詞．
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．（名詞短語）
═If you give me one more hour，I'll get the work finished．（if條件句）
═If I am given one more hour，I'll get the work finished．
