Passage One

Question 21 to 25 are based on the following passage.

Every generation has its defining works. More than 300,000 people worked to put a man on the Moon. Millions of more people built the Hoover Dam and other great projects. These projects didn’t just provide purpose for the people doing those jobs; they gave our whole country a sense of pride that we could do great things.

Now it’s our turn to do great things. I know, you’re probably thinking: I don’t know how to build a dam, or get a million people involved in anything. But let me tell you a secret: No one does when they begin. Ideas don’t come out fully formed. They only become clear as you work on them. You just have to get started.

It’s good to be idealistic. But be prepared to be misunderstood. Anyone working on a big vision will get called crazy, even if you end up right. Anyone taking the initiative will get criticized for moving too fast, because there’s always someone who wants to slow you down. In our society, we often don’t do big things because we’re so afraid of making mistakes that we ignore the fact that all the things will be wrong today if we do nothing. The reality is, anything we do will have issues in the future. But that can’t keep us from starting.

So what are we waiting for? It’s time for our generation-defining public works. How about stopping climate change before we destroy the planet and getting millions of people involved in manufacturing and installing solar panels? How about curing all diseases and asking volunteers to track their health data and share their genomes (基因组)? How about modernizing democracy so everyone can vote online, and personalizing education so everyone can learn? These achievements are within our reach. Let’s do them all in a way that gives everyone in our society a role.

21. Putting a man on the Moon and building the Hoover Dam are mentioned as ____ that every generation has its defining works.

A. effects

B. reasons

C. examples

D. definitions

题目解答

答案

题目考察对文章第一段的理解。作者通过“Putting a man on the Moon”和“building the Hoover Dam”两个例子，说明每一代都有其标志性成就。这些项目不仅为参与者提供了目标，也增强了国家自豪感。根据上下文，这里需要一个词来概括这两个事例的作用。

A. effects：效果。不符合，因为这两个项目是原因而非结果。
B. reasons：原因。不符合，因为它们是例证而非原因。
C. examples：例子。符合，作者用这两个项目作为“每一代都有其标志性成就”的例证。
D. definitions：定义。不符合，因为它们不是定义性内容。

综上，正确答案是C. examples。

答案：C. examples

解析

本题考查对文章细节的理解以及对词汇含义的把握。解题的关键在于理解作者提及“将人类送上月球”和“建造胡佛水坝”这两个事件的目的，以及分析各个选项与文章内容的匹配度。

  1. 首先明确文章第一段的核心观点是“Every generation has its defining works”（每一代人都有其标志性的成就）。
  2. 接着看作者提到“More than 300,000 people worked to put a man on the Moon. Millions of more people built the Hoover Dam and other great projects”，这里详细描述了这两个项目的参与人数等情况，是为了具体说明前面提出的每一代人都有标志性成就这一观点。
  3. 然后分析各个选项：
    • A选项“effects”（效果），这两个项目本身并不是“每一代人都有标志性成就”这一观点的效果，而是用来支撑该观点的具体事例，所以A选项不符合。
    • B选项“reasons”（原因），它们不是导致“每一代人都有标志性成就”的原因，而是作为例子来体现这一现象，所以B选项不正确。
    • C选项“examples”（例子），作者正是用这两个项目作为“每一代人都有其标志性成就”的例证，符合文章的逻辑和表达意图，所以C选项正确。
    • D选项“definitions”（定义），这两个项目并非是对“每一代人都有标志性成就”的定义，所以D选项不合适。
