单项填空题解题技巧十法详解一：语境法

 　在处理知识与能力的关系时，很注意在尽可能真实与自然的语境中考查知识的掌握与运用情况，因而对词语辨析、时态选择和某些语法知识常置于一定的语境中。
　　1. If you want to change for a double room you'll have to play ______ $15.
　　A. another B. Other C. more D. each
　　由上下文if you want to change for a double room可推知，必须另外再加钱，故用another，"再加15美元"，即another 15 dollars. 故正确答案为A。而C项应为$15 more.
　　2. ----He promised to come to see you.
　　----But he ____ I've been alone.
　　A. doesn't B. didn't C. won't D. hasn't
　　该题是在语境中考查动词的时态，很容易因为前文中"He promised"而误选B项。事实上，应注意"I have been alone."是分析空格处时态的重要依据。"他不仅过去没有来，而且现在仍然没有来。"故正确答案为D。
　　3. ----It's getting late. I'm afraid I must be going now.
　　----OK. _____.
　　A. Take it easy B. Go slowly C. Stay longer D. See you
　　考生容易受中文思维的影响而误选B. 实际上，根据英文习惯表达应选D. A C项不符合语境，see you是很常见的口头语，意思为"再见"，相当于Goodbye / See you soon / See you later.
