Further, students might be helped by a course【C3】______considers the computer’s impact【C4】______society. But that is not【C5】______is meant by computer literacy.

   【C7】______how to use a computer and learning how to program one are two distinct activities.

【C1】

选项 A、moreover
B、for
C、whereas
D、though

答案B

解析 这四个单词有不同的意思和词性。moreover是副词,其意思是“而且,加之,再者,此外”,它的后面要用逗号与它所修饰的句子分开,如“The proposal was not well thought out;moreover,it would have been too expensive.”for是并列连词,表示解释补充说明性的原因。whereas可作连词,其意思是“然而,但是,尽管”,表示对照,如“She is intelligent, whereas he is lazy.”though可作从属连词和副词,其意思是“虽然,尽管,即使,不过”,表示让步转折;其作副词时,一般用在句末。这四个单词分别表示前后两句的递进关系、因果关系、对照关系和让步关系。从上下文来看,后一句是表示原因,所以应选B。
