Many Children ________ the Internet , and _____had a bad effect on their studies.

A．are addicted to; it	B．get engaged in; which
C．are related to; what	D．are addicted to; which

Answer 1

       A   

     题意：很多孩子迷恋与因特网，这对他们的学习产生坏的影响。be addicted to 意思是“对…上瘾”， And 是一个并列连词，后面应该是并列句，而不是从句，因此排除B和D。be related to“与…有关”，不符合题意，因此排除。
