Text{{/B}} There 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 driven,
{{U}} {{U}} 1 {{/U}} {{/U}}people should have some basic idea of
how the things that they use {{U}} {{U}} 2 {{/U}} {{/U}}what
they do. Further, students might be helped by a course {{U}} {{U}}

单选题
A. moreover
B. for
C. whereas
D. though
【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。

B. perform
C. do
D. undertake
【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。
