问题 单项选择题

登顶的路上设置的种种困难,寒冷、缺氧、大风等恶劣的自然因素也同样考验你的心智,每一个挑战者都要接受严格的筛选,要走完这8848米绝非______,在这段时间里必须把握住瞬间的机会,否则会和登顶的机会______。
填入横线部分最恰当的一项是( )。

A.一日之功失之交臂
B.一蹴而就谬以千里
C.一气呵成 结不解缘
D.一步登天 有缘无分

答案

参考答案:A

解析: “一日之功”指成功做某事并不是一日的功力,强调时间和功力的积累。“一蹴而就”,指踏一步就成功;比喻事情轻而易举,一下子就成功。“一气呵成”,一口气做成,形容文章紧凑、连贯,也比喻做事紧凑、不间断。“一步登天”,比喻一下达到很高的境界、程度,也比喻人一下子爬上高位,多含贬义。第一空可以排除C、D两项。“失之交臂”,当面错过机会。“谬以千里”,指错误荒谬到了极点。文中的意思即为如果没把握住瞬间的机会,就会失去登顶的机会,排除B项。正确答案为A。

单项选择题

Congress makes the laws in the United States. It has two parts, which are more or less equal in power. They are known as the House of Representatives and the Senate. The House of Representatives is larger than the Senate whose 100 members (two from each state) serve for six years. The 435 members of the House are elected every two years, and the number from each state is determined by the population of the state. For example, California, which has a large population, has 43 representatives, while the State of Nevada has only one.
The House and Senate are divided into small groups which take care of special matters such as education or foreign affairs. The most important work of Congress is often done in these groups, which are called subcommittees.

In the U.S. Congress, the House of Representatives and the Senate are______.
A. not equal. The House is more powerful
B. almost equal in power
C. not equal. The Senate is far more powerful
D. different. The House is more important

According to the Constitution of the United States, a senator must be at least 30 years old and he must have been a citizen of the United States for nine years at the time of his election. To be elected to the House a person must be 25 years old and must have been a United States citizen for seven years. At the present time, members of Congress include businessmen, farmers, teachers, and especially lawyers. In general, senators are better known than representatives because they are fewer in number and serve for a longer time. Many American presidents served in Congress before they became president.
