Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.
The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中风 ) are examples of such diseases.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.
Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones ( 家畜 ). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.
67. What is the main cause that people suffer from a lot of new sicknesses?
A. Ancient people did a great deal of physical exercise.
B. People today have a lot of alcohol.
C. People today have more tobacco.
D. Food today is quite different from that of ancient times.
68. Which of the following belongs to the dairy products?
A. Milk B. Corn C. Pork D. Flour
69. New kinds of sicknesses have been found because ________.
A. the human body has changed compared with humans who first appeared on the earth
B. the way we live has changed a little
C. our body can’t deal with the changes in life style
D. the way we live today is proper for the human body
70. According to some scientists, Stone-age people were much healthier than people today because they ate a lot of ________.
A. milk and other dairy products B. salt and sugar
C. wild animals, fresh wild vegetables and fruits D. grain foods
With the rapid social development, the Internet now provides social networks that include online movies and videos．The major television networks have much less control over your mind and their broadcasts for entertainment and, more importantly, advertising．It has long been known that television’s audience will spend more time on the Internet than watching TV．People have found another means of entertainment by going to websites which seem to satisfy their specific interests more completely．This isn’t very good news for the television networks．
The influence of people using DVRs （Digital Video Recorder） also has led to fewer and fewer viewers watching television commercials．Market research indicates the effectiveness of TV ads is getting weaker as a result．Many DVR owners are fast forwarding and skipping television commercials．With viewers now spending an average of four times longer on the Internet and more viewers avoiding commercials, this trend isn’t good for television’s advertising revenues（收益）．
Major TV advertisers know full well that their advertising dollars on TV aren’t as an effective investment as they once were．The major players in advertising have been moving towards the Internet as a serious alternative means of advertising．
For thousands of people involved in Internet marketing, it’s history-making to share the revenue that previously all went to major television networks．There’s already a group of Internet marketers being paid a larger amount of advertising revenue．These are everyday people that work usually from home on their own．Advertisers can direct their advertising to websites where viewer types are more likely to be interested in their product or service．
The development of the Internet and its role and change in our lives cannot be compared to any other form of media created throughout the history of mankind．People are going to websites for entertainment because _______．
| A．they’d like to follow the last trend |
| B．there are fewer commercials |
| C．there are more movies and videos |
| D．they can choose what meets their particular needs |
We can learn from the second paragraph that ______．
| A．viewers are bored with television commercials |
| B．the television viewing time should be limited |
| C．many television commercials are of poor quality |
| D．there are more commercials on DVRs than on TV |
It can be inferred from the passage that _____．
| A．people spend time on the Internet mainly for entertainment |
| B．most people prefer to work at home nowadays |
| C．the Internet will attract more and more advertisers |
| D．the appearance of TV changed our lives |
The passage mainly tells us ________．
| A．the rapid social development |
| B．the fast development of the Internet advertising |
| C．the way to advertise on the Internet |
| D．the influence of television commercials |
“To be or not to be”.Outside the Bible, these six words are the most famous in all the literature of the world.They were spoken by Hamlet when he was thinking aloud, and they are the most famous words in Shakespeare because Hamlet was speaking not only for himself but for every thinking man and woman.To be or not to be----to live or not to live, to live richly and abundantly and eagerly, or to live dully and meanly and scarcely．A philosopher(哲学家) once wanted to know whether he was alive or not, which is a good question for everyone to put to himself occasionally.He answered it by saying, “I think, therefore I am.”
But the best definition of existence I ever saw was one written by another philosopher who said, “To be is to be in relations.” If this is true, then the more relations a living thing has, the more it is alive．To live abundantly means simply to increase the range and intensity （强度）of our relations．Unfortunately, we are so constituted (自作决定的)that we get to love our routine．But other than our regular occupation, how much are we alive? If you are interested only in your regular occupation, you are alive only to that extent．So far as other things are concerned----poetry and prose, music, pictures, sports unselfish friendships, politics, international affairs----you are dead.
On the contrary, it is true that every time you acquire a new interest----even more, a new accomplishment----you increase your power of life．No one who is deeply interested in different kinds of subjects can remain unhappy.The real pessimist is the person who has lost interest．
Bacon said that a man dies as often as he loses a friend．But we gain new life by contacts with new friends, and new ideas and thoughts, too．Where your thoughts are, there will be your life also．If your thoughts are limited only to your business, only to your physical welfare, only to your narrow circle of the town in which you live, then you live in a narrow restricted (有限的) life．But if you are interested in the characters of a good novel, then you are living with those highly interested people; if you listen intently to fine music, you are always away from immediate surroundings and living in a world of passion and imagination．
To be or not to be ---- to live intensely and richly, or merely to exist, that depends on ourselves.Let us widen and intensify our relations．While we live, let us live．What does the author mainly want to do by this passage?
| A．Argue against an idea． | B．Put forward an idea． |
| C．Introduce some famous sayings． | D．Explain some famous sayings． |
What does the underlined word “pessimist” most probably mean?
| A．Somebody who always expects the worst to happen． |
| B．Somebody who is always interested in making new friends． |
| C．Somebody who always lives in a world of passion and imagination． |
| D．Somebody who likes to live a rich and abundant life． |
Which of the following behaviors is most probably NOT encouraged by the author?
| A．Thinking more than your own business． |
| B．Caring only about your physical welfare． |
| C．Reading good novels． |
| D．Listening to fine music． |
What is the main idea of the passage?
| A．To be or not to be, that is a question． | B．I think, therefore I am． |
| C．To be is to be in relations． | D．A man dies as often as he loses a friend． |
Many of the most damaging types of weather begin quickly, strike suddenly, and disappear rapidly, destroying small areas while leaving neighboring areas untouched. Such event as a tornado(龙卷风) struck the northeastern part of Edmonton, Alberta, in July 1987. Total damages from the tornado went beyond $250 million, the highest ever for any Canadian storm.
Traditional computer models of the atmosphere have limited value in predicting short-lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the slight atmospheric changes that come before these storms. In most nations, for example, weather-balloon observations are taken just once every twelve hours at places separated by hundreds of miles. With such limited data, traditional forecasting models do a much better job predicting general weather conditions over large areas than they do forecasting specific local events.
Until recently, the observation intensive (十分细致) method needed for exact, very short-range forecasts, or “Nowcasts,” was not possible. The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties concerned in rapidly collecting and processing the weather data from such a network were hard to overcome.
Fortunately, scientific and technological advances have overcome most of these problems. Radar(雷达) systems and satellites are all able to make detailed, nearly continuous observation over large areas at a lower cost. Communications satellites can send out data around the world cheaply and immediately, and modern computers can quickly collect and analyze this large amount of weather information.
Meteorologists(气象学者) and computer scientists now work together to design computer programs and video equipment able to change weather data into words and graphic displays(图解) that forecasters can understand easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, nowcasting is becoming a reality.Why can’t traditional computer models predict short-lived local storms?
| A．The weather data people collect are often wrong. |
| B．Detailed weather data in some small areas are not available. |
| C．The computers are not advanced enough to predict them. |
| D．The computers are not used to forecast specific local events. |
The word “Nowcast” in Paragraph 3 means .
| A．a network to collect storm data |
| B．a way of collecting weather data |
| C．a more advanced system of weather observation |
| D．a forecast which can predict weather in the small area |
What can make “Nowcasts” a reality according to the passage?
| A．Scientific and technological advances. | B．Advanced computer programs. |
| C．Computer scientists. | D．Meteorologists. |
What does the passage mainly talk about?
A.The advantages of “Nowcatsts”.
B.A tornado in Edmonton, A1bertA.
C.The difficulty in predicting tornado.
D.A great development in weather forecast.
