(单选题)
It is said that the agreement ______ between the two companies last month will become effective from May 1st.
A.to sign
B.to be signed
C.signed
D.signing
参考答案:C
参考解析:
考查过去分词作定语。句意:据说这两家公司上个月签署的协议将从5月1日起生效。分析句子成分可知,that从句引导的是主语从句,主语从句中的主干成分是the agreement will become effective from May 1st,______ between the two companies last month为非谓语动词充当后置定语,意为“这两家公司上个月签署的”,结合后置定语的时间状语last month,且sign和the agreement之间为被动关系,因此空格处应该填入过去分词signed。故选C。
