问题 To survive in the intense trade competition between countries, we must______the qualities and varieties of products we make to the world market demand.
选项 A、improve
B、enhance
C、guarantee
D、gear
答案D
解析 动词词义辨析。分析句子的成分，句子的主语we，宾浯补足语the qualities and varieties ofproducts，定语从句we make修饰前面的名词，所以句意是空格填入的动词与the world marketdemand搭配。选项中，只有gear(使……适合)符合句意。guarantee意为“保证”。
