  • chatting online can be _fun,but kids must be sure they stay safe on_web

    A./ ;a B.a;the C./;the D.a;a

    选C.

    be fun很有趣,常用短语,不含冠词.

    web表示“网页”经常加定冠词或形容词性物主代词、所有格.如:

    So we have meetings--big meetings -on【 the web 】for disclosure of important information.

    因此有大型的网络会议,用于在网上宣布重要信息

    但注意:“一个网址”:a web site.
