问题 Vielle Software releases free trial versions of its products______potential customers can try out the programs for a limited time.

选项 A、despite
B、so that
C、or
D、though

答案B

解析 此句的主要成分“Vielle Software releases free trial versions”是一个完整的句子,故应将“______potential…time”看成修饰成分。此修饰成分中包含谓语can try,因此选项中可引导修饰成分的状语从句引导词(B)和(D)为备选答案。根据上下文语义,此处应意为“为使潜在的顾客们能够试用产品而提供了免费体验版”,故表示目的的(B)so that(以便)为正确答案。如选择表示让步的状语从句引导词(D)though(尽管),则意为“尽管潜在的顾客们能够试用产品,但还是提供了免费体验版”,句意不通顺。介词(A)和并列连词(C)不能引导此修饰成分。
