1．This has been a timely reminder of the need for ________ care.

A．tentative　　　　　　　　 B．constant

C．permanent D．primary

答案与解析：B　constant"持续的，不断的"。句意：这件事适时地提醒我们要注意时时谨慎。tentative"不确定的，踌躇的"；permanent"永久的"；primary "主要的，初期的，基本的"。

2．The secretary was allowed ten more minutes. She ________ her boss' patience and tried to hurry.

A．sensed B．tolerated

C．realized D．understood

答案与解析：A　考查动词辨析。老板多给的十分钟使秘书感到了(sense)老板的耐心。如果忽略了后面的"and tried to hurry"就很容易误选C项。

A．request B．demand

C．inquiry D．proposal

答案与解析：A　request"请求"，put in a request for"提出请求"。demand"需求，需要"，inquiry"询问"，proposal"建议"，均不合题意。
