1. A It couldn’t be better意思是“再好不过了”，是对别人邀请的回答，而Of course you can表达生硬，不符合交际用语习惯，If you like是对别人请求的回答，It’s up to you意思是“随便”。

2. D means是单复数相同的名词，从空前的every我们知道，means在这里是单数，同时它与try间的关系是被动的，因此用被动语态。

3. B A有较大干扰性，what引导的是名词性从句，而这里需要的是boy后的定语从句，因此用whom。

4. D 从空后的Here you are.我们知道，说话人同意，因此用by all means意思是“行；可以没问题”。

5. A There is no possibility that为固定句型，意思是“没有可能……”。
