is no denying that students should learn something about how computers work,
just as we expect them at least to understand that the internal-combustion
engine has something to do with burning fuel, expanding gases and pistons being

{{/U}} is meant by computer literacy. For computer literacy is not a form of
literacy; it is a trade skill that should not be {{U}}(31) {{/U}} as a
liberal art. {{U}} (32) {{/U}} how to use a computer and
learning how to program one are two distinct activities. A {{U}}(33)
{{/U}} might be made {{U}}(34) {{/U}} the competent citizens of

{{U}}(38) {{/U}} while our society needs some people who are experts at

violin-making. Learning how to use a computer is not
{{U}}(40) {{/U}} difficult, and it gets {{U}}(41) {{/U}} all the

that in the future everyone is going to have to know how to use a computer to be
a {{U}}(43) {{/U}} citizen. What does the phrase "learning to use a

if there is {{U}}(44) {{/U}} set of definite skills that, {{U}}(45)
{{/U}} acquired, enable one to use a

【正确答案】
B
【答案解析】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。
【正确答案】
D
【答案解析】通过分析句子结构，我们知道这里缺少一个及物的谓语动词，虽然选择枝中的四个动词都符合这个要求，但后面what they do提醒我们选择一个与do相同的动词，即D。
