Question

    There is one thing that can ruin vacations, make business meetings less than successful, and can cause more problems than anything else for air travelers. Jet lag!

1.The travel time is too fast for the human body to adjust easily. Long distance air travel to a new time zone disrupts (打乱) three important senses: the sense of place, the sense of time, and the sense of well-being.

Sense of place: To some degree, all locations are geographically and even chemically different from one another. Humans, like all living things, have a strong sense of place. 2.

Sense of time: We all also have a natural sense of time that is linked to our sense of place. Our bodies function on a program that takes about a day to run.3.This is why travel to a distant time zone makes us miss the usual hometown patterns of something as simple as the times of sunrise and sunset.

Sense of well-being: We have a sense of well-being when we are healthy and happy. 4.That is why flying to a new environment and time zone often causes a disruption in our sense of well-being.

For thousands of years, people didn’t experience disruption in their sense of time and place because there were no rapid means of transportation.5. However, although we can travel by plane now, our bodies have not yet adapted to long-distance air travel. That is why we suffer the jet lag.

A.The invention of the airplane changed all this.

B.We can make the effort to overcome the jet lag.

C.They sense the different qualities of dawn, noon, and midnight.

D.Jet lag results from traveling a long distance to a new zone.

E.This sense is strongly connected to our senses of place and time.

F.It took weeks, months, years, or even generations to travel great distances.

G.This makes people homesick for familiar surroundings and wish for their own bed

1.D

2.G

【解析】

这是一篇说明文。文章讲述了时差反应会打乱我们的空间感、时间感以及我们对身体健康的感觉，所以坐飞机长途旅行后，时差反应会让我们感到不适。

1.考查上下段内容的衔接。空格位于段首。第一段段意为：对于坐飞机旅行的人来说，有一件事情能毁坏你的假期、让会议不成功或者比其它事情能引起更多的问题，这就是时差反应。所以第二段首句应对第一段提出的中心词（jet lag）做进一步的解释。D选项（长途旅行后进入到一个新的时区就会引起时差反应）中的jet lag与首段中心词呼应，其中的traveling a long distance与下句中的The travel time呼应，故选D。

2.考查段落内容的一致性。空格位于段尾，根据这一段的中心词Sense of place(空间感)可知，这一段内容都是围绕空间展开的。G选项（这使得人们更加想念他们熟悉的环境，想要他们自己的床）中的familiar surroundings与their own bed表达的都是空间概念，并且其中的this与上句（像其它所有的生物一样，人有强烈的空间感）可形成指代关系。故选G。

3.考查段落内容的一致性。空格位于段中，根据这一段的中心词Sense of time(时间感)可知，这一段内容都是围绕时间展开的。C选项（它们能感知到黎明、中午和午夜的不同）中的dawn, noon与midnight表达的都是时间概念，并且其中的they与上句中的our bodies可形成指代关系。故选C。

4.考查上下句之间的衔接。空格位于段中，根据这一段的中心词Sense of well-being(身体舒适感)可知，这一段内容都是围绕身体舒适感展开的。E选项（这种感觉与我们的空间感、时间感紧密相关）中的this与上句中的a sense of wellbeing形成指代关系，其中的place and time与下句中的a new environment and time zone呼应。故选E。

5.考查上下句之间的衔接。空格位于段中。空格上一句句意为：几千年以来，由于人们没有快速的交通工具，所以他们不会被时空感打扰。A选项（飞机的发明改变了这一切）与上句可形成很好的衔接关系。并且选项A中的The invention of the airplane（飞机的发明）与下句中的although we can travel by plane now(尽管现在我们可以坐飞机旅行)前后呼应。故选A。
