单选题

Of all the sciences, only two are subjects that have a direct (直接的) and noticeable effect on our lives every day. One is meteorology, the study of weather. Heat, cold, sun and rain affect us in many ways—in the kind of clothing we wear, for example, and the types of activities we do outdoors. Economics is the other science that affects the everyday lives of all of us. Each time we spend money, or it is spent on us, we are contributing (贡献) the economic life of our country and, in fact, of the world.
Most people have a basic understanding of the weather, but how many people feel comfortable with the subject of economics? Often, economics seems to be a mysterious (神秘的) subject. Newspapers and television use terminology (术语学) that can resemble (像；类似) a foreign language. They speak of the gross national product, the cost of living, the prime rate, the money supply, productivity, the unemployment rate, the balance of payments, and so forth.
In some ways, economics is like an enormous jigsaw puzzle (拼图游戏). Each piece is basic, but the pieces interconnect, one to another, in a large picture. To look at the whole picture, you must begin piece by piece.

单选题 Next the author will most probably talk about ______.

【正确答案】 A

【答案解析】先来分析一下文章的结构，根据作者叙述的顺序推断出他下一步该讲什么。文章的第一段提出两个概念“meteorology”和“economics”；第二段通过对这两种学科的比较，说明“economics”很复杂，一般人并不熟悉；第三段承接第二段，进一步说明“economic”的复杂性，并以“you must begin piece by piece”作为过渡句。由以上分析可以看出，作者紧接着会谈到如何研究“economics”的问题，这与选项A的内容相符。

单选题 When talking about the weather, the author suggests that ______.

【正确答案】 C

【答案解析】文章中作者虽然提到了天气，但“meteorology”并不是本文讨论的重点，只是用它和“economics”作比较，突出“economics”的复杂性。在第二段中有这样一句话“Most people have a basic understanding of the weather...”，再根据它和“economics”的比较可以推断出：人们对于天气还是多少有一定的了解的。由此可见，正确答案是C。

单选题 Which of the following is TRUE?

A、 Economics is the only science that affects our lives.
B、 Economics is so complex that there are many terms (术语) that we can not understand.
C、 People only know a little about meteorology.
D、 Economics is a science about spending money.

【正确答案】 B

【答案解析】根据第二段的“Newspapers and television use terminology that can resemble a foreign language.”可以看出，经济学如此复杂，以至于报纸、电视上出现的术语就像是外语一样(让一般人无法理解)。由此可以看出，选项B是正确答案。

单选题 The passage suggests that we should examine economics little by little because ______.

【正确答案】 C

【答案解析】文章的最后一段将经济学比作拼图游戏，每一个小块都是基础，而整体又如此复杂，所以研究它时必须从小处着手，一步一步地来。选项C的内容与此意思相同，所以是正确答案。
