精英家教網 > 高中英語 > 題目詳情

Nowadays, it is possible to travel to distant parts of the globe in several hours. This can result in the traveler ending up in a part of the world where time is different from his or her own “body clock” ,which control our sleep patterns.

If we travel east or west by more than four time zones (hours) then we will usually be affected.

In the past when people traveled by sea, there was enough time for the body to adjust to the local time, but with the advent of modern high speed aircraft the body does not have time to adjust. Therefore, there is the term “jet lag(時差反應)”. It normally takes one day per time zone (hour) for the body to adjust to its new surroundings.

The effects of jet lag are usually tiredness and insomnia (失眠) but can also include: poor concentration, nausea (惡心) ,vomiting (嘔吐), constipation (便秘) and general malaise (不舒服). The effects are made worse by alcohol.

Sleeping while flying may help to reduce the symptoms (癥狀) of jet lag, but long periods of immobility aboard aircraft can make the traveler feel numb(麻木的) in the legs. The following are some other tips of reducing the symptoms of jet lag:

①Avoid traveling when you are already tired and rest before departure.

②Stopovers on long flights may be helpful.

③A relaxed flight is important.

④Sleeping tablets will help you to sleep and be correspondingly alert (相對警惕的) during the next day, but they do not speed up adjustment to the new time zone.

⑤Remember the actual traveling time will usually be at least twice the actual time spent in the air since it will include traveling to and from and hanging around in airports.

⑥Avoid heavy commitments on the first day after arrival.

72. The following are the effects of jet lag EXCEPT _____.

        A. tiredness          B. coughing           C. insomnia           D. vomiting

73. The word “immobility” in the fifth paragraph means “_____”.

        A. stillness           B. movement         C. activity             D. happiness

74. We can reduce the symptoms of jet lag by _____.

        A. drinking some alcohol           B. keeping ourselves awake

        C. taking some medicine            D. sleeping while flying

75. What is the main purpose of the passage?

        A. To suggest people travel by sea instead of by air.        

B. To tell people the effects of jet lag.

        C. To give people some advice about reducing the symptoms of jet lag.

        D. To tell people about their body clock.

71—75 BADC


解析:

時差反應就是人們在旅行4個時區后產生的失眠、嘔吐、惡心等癥狀,本文將介紹如何減輕時差反應。

72. B。對照文章第四段The effects of jet lag are usually tiredness and insomnia but can also include: poor concentration, nausea, vomiting, constipation and general malaise.

可以輕松找到答案。

73. A。從文中Sleeping while flying和make the traveler feel numb in the legs“使旅客腿部麻木”可以猜測到最長時間的不活動。

74. D。從文章最后一段Sleeping while flying may help to reduce the symptom of jet lag…可知。

75. C。文章先解釋了什么叫jet lag,然后闡述了jet lag給人帶來的不適,最后給出一些建議,所以這篇文章的主要目的還是告訴人們一些如何應對jet lag的方法。

閱讀理解:
A
There are three branches of medicine. One is called “doctor medicine,” or “scientific medicine.” Scientific doctors try to observe sicknesses, look for logical patterns, and then find out how the human body works. From there they figure out what treatments may work. This kind of medicine is believed to date from the 4th century BC. Although nowadays it is successful, in the ancient world this approach probably did not cure many patients.
A second kind of medicine is called “natural cures,” or “folk medicine,” in which less educated people try to cure sicknesses with various herbs(中草藥). These folk healers also use observation and logic, but they are not so aware of it. They try things until they find something that seems to work, and then keep doing that. Folk medicine flourished long before the development of scientific medicine and was more successful in ancient times than doctor medicine.
The third kind is called “health spas,” or “faith healing.” Sometimes this may be as simple as touching the holy man and being immediately healed. Other times, a magician may make you a magic charm, or say a spell, to cure you. Some religious groups organize special healing shrines for the sick. In these places people rest, get plenty of sleep, eat healthy food, drink water instead of wine, and exercise in various ways. They also talk to the priests and pray to the gods. If you are feeling depressed or you have been working too hard, going to these places may be just the right thing to make you feel better.
1. Doctor medicine ________.
A. has a longer history than folk medicine
B. has been practiced for around 1,600 years

A. Folk healers choose different herbs to cure diseases without any sound basis.
B. People who practice folk medicine need lots of formal education on herbs.
C. The success of folk medicine led to the development of doctor medicine.
D. Natural cures worked better than scientific medicine in ancient times.

Hey there,
So you’re about to spend four years of your life and tens of thousands of dollars of your parents’ money, and all you really know about college is that all of your friends are going. Do you ever stop to wonder why you’re going?
Relax. You’re making the right decision. First of all, you’ll discover what interests you by taking courses in many subjects. For example, it’s hard to decide if you want to be a painter if you’ve never painted any pictures; once you’re in a drawing-room on campus, you’ll know one way or the other. College is also a lot of fun—after you graduate, you’ll be working every weekday for 50 or so years. And remember that college graduates get about twice the income of those who never attended college.
Finding the right college can be difficult. Fortunately, Johnson Review is here to help you every step of the way.
Researching School. To us, the most important decision you’ll make is to choose the school that really fits you best---- not the one that is the most competitive or has the best-equipped rooms.
Applying to School. On JohnsonReview.com, you’ll find hundreds of actual college applications(申請) and links to many more.
Raising Your Scores. American College Test is one of the most important parts of the admissions(錄取) course. It’s not the most important, though, and not everyone needs to prepare for the best. But, if you think you can do better, find the right course for better scores.
Paying for School. Most families need financial aid for the high cost of college. The problem is that financial aid seems difficult to get and many families get caught up in the price of college. However, if you really do your research, you’ll learn that there are many ways to get financial aid and that you can afford to attend any college, no matter the cost.
For more information, call 600-3681 or visit Johnson Review.com, wherever you go, have a nice trip!

請認真閱讀下列短文,并根據所讀內容在文章后表格中的空格里填入最恰當的單詞。
注意:每空格一個單詞。
Some people believe that greed and selfishness has become the basis of modern society. We should return to the old traditions of family and community, and then we will have a better life. To what extent do you agree or disagree with the above opinion?
In this fast-paced world, many values are undergoing major changes. While people traditionally prioritize(區分優先次序) caring, sharing and generosity in life and work, modern people seem to be more self-absorbed and self-concerned.
Modern people act selfishly to survive the harsh competition of life. They say that it is a jungle out there. To survive, you have to fight with whatever means that come handy. Obviously greedy and selfishness go perfectly well with such ideas. In a company, employees do everything they can to get better pay and higher position, even at the cost of colleagues. We are in any way advocating any selfish conduct. It is just that people are pressured to act in a certain way due to outside influences.
In spite of common practice, it is hard to conclude that modern society is built on greed and selfishness, both of which are not newly invented vocabulary. In ancient times people also did greedy and selfish things though such behaviors were more condemned(譴責) then. But we cannot ignore the fact that people in the past lived a relatively more isolated life and faced less pressure compared with their modern twins.
Are we happier to share with others and be generous to them? There is no fixed answer either. Some people take great pleasure helping and giving to others while others feel happy doing the opposite. But I personally think that people should not be too selfish. Caring for others can actually encourage the development of a mutually beneficial relationship.
In conclusion, modern people appear to be more self-centered than those in the past due to strong outside pressure. However, we should encourage people to know the importance of being caring and generous and to build a mutually beneficial relationship with others.
Title: Are Modern People Becoming More Selfish?

Main comparisons
Contexts
 
In the past people put caring, sharing and generosity in the (2)_________ place.
Nowadays, people seem to be more (3)_________ about themselves.
 
People in the past appeared to be modest and self-effacing(謙讓).
