A．it                           B．that                        C．which                    D．one

【回答】

A

【詳解】

考查代詞。句意：預防艾滋病的知識應定期在大學教授，因為這可能對防止學生感染艾滋病產生影響。當that在定語從句中做賓語時可以省略，所以可以判斷空格應該填it指代主句主語“Prevention of Aids”，恢復句子是“because of the effects that it can have on keeping students from being infected with Aids”。故選A。

【點睛】

在定語從句中，that充當主語時不可省略，但作為賓語時可以省略。在這道題中定語從句的賓語that省略了，所以可以判斷空格應該填it指代主句主語“Prevention of Aids”，恢復句子是“because of the effects that it can have on keeping students from being infected with Aids”。故選A。
