1.B2.C3.C4.C

觉得3题应该选a，4题不太理解

老师能不能统统解释一下啊

解析：
1. W：Bill认为你不应该用你这把好用的刀修理。
  M：他为什么在乎呢？不是他的刀子。这个男人的隐含的意思是这件事
     并不是Bill所关心的。
     所以正确答案应该选择B。
2. W：难道我们不应该邀请更多的人参加舞会吗？
  M：越多越开心。
     这个男人的隐含的意思是人多的舞会才最有意思。
     所以正确答案应该选择C。
3. W:今年注册应该会比以往容易。
  M：除非电脑坏了。
     把第二句话补全了应该是：Registration will be easier unless
          the computer breaks down. 在口语交际中，如果是对动词的重复，
    一般表示不同意这种做法。所以正确答案应该选择C。
4. W:你要加班吗？
  M：偶尔。
     Every so often是偶尔的意思。相当于occasionally，所以正确答案应
     该选择C。

学习非常愉快，有收获！谢谢！
