问题 This is a new model of ______ typewriter especially designed to meet the needs of traveling businessmen.

选项 A、flexible
B、mobile
C、portable
D、active

答案 C

解析 形容词辨义。这四个选项都是形容词形式,flexible表示“柔韧性,易曲的,灵活的,柔软的,能变形的,可通融的”;mobile表示“可移动的,易变的,机动的”;portable意指“轻便的,手提(式)的,便携式的”,如:a portable book-computer(便携式笔记本电脑);active表示“活动的;活跃的”。根据句意,此处是一种新型的便携式打字机,所以portable符合题意。
