单选题 The conveniences that Americans desire (reflecting) not so much a (leisurely) lifestyle as a busy lifestyle in which even minutes of time (are) too valuable (to be wasted).
【正确答案】 A
【答案解析】reflecting 改为 reflect。句中that Americans desire是定语从句，修饰先行词The conveniences。A．reflecting 应当是主句的谓语，但它是现在分词，不可单独作谓语，所以要改为reflect。
