expensive vs. expansive
释义：前者应该是个中国学生很早就学到的词，形容和金钱相关的“昂贵”。而后者是和expand相关的，可在留学文书里用于形容“可延展性”、性格的“豁达”、或者空间相关的“辽阔”。
例句：
The market will not collapse, but it will be a ton more expensive and cover many fewer people.
We at length came abreast of the expansive, glittering lake, which divided the ample meadows.
