     into use in April 2000, the hotline was meant for residents reporting water and heating supply breakdowns.

       A．Put                     B．Putting                C．Having put           D．Being put

【回答】

A

解析： 本题考查非谓语动词。首先排除B,C两个选项，因为热线是被投入使用，然后分析比较A,D两个选项，D选项表示正在被投入使用，与时间状语不吻合。如果考生指代过去分词可以作时间状语的话，那么本题可以直接找出*，本句话可以改为：（when it was）put into use in April 2000. the hotline means for residents reporting water and heating supply breakdowns.
