⒈if____,he promises that he will spare no effort in promoting public welfare.
A elected B elect C electing D being elected
⒉If law and order_____not preserved,people will not be able to live a secure life.
A are B were C is D was
A elected B elect C electing D being elected
⒉If law and order_____not preserved,people will not be able to live a secure life.
A are B were C is D was
1.答案是A.这是连词和分词连用或者句子的省略，因为分词elect和主语之间存在被动关系，所以用过去分词。
2.答案是C。law and order的意思是“法制”，是单数含义，所以谓语动词用单数。
