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.

But this is quite different【C11】______saying that all ought to know how to program one.【C12】______that to people who have chosen programming as a career.

【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。
