第6题

Two hundred years ago, it took several weeks for the news of the important Battle of T
rafalgar to reach London.Nowadays, you can watch a terrorist attack as it happens anywhere in the world.The communications revolution means that we are constantly bombarded with instant news.This has great advantages, but it also raises important questions.

Satellites have enabled immediate reporting worldwide.A reporter can send the news to a network like CBS News and within seconds it can be all over the world.They send electronic reports that go straight into the newspaper or onto the TV screen.Reporters can now also transmit images through their mobile phones.Consequently, live, “on-the-spot” reporting has become the norm and TV viewers can get a much better idea of what a natural disaster, a conflict or an interesting scientific discovery is like.

In recent years, several changes have occurred in the ownership of news media.Networks owned by large companies and governments have become bigger and very powerful.These networks – such as BBC News 24–are hungry for news and have huge audiences.However, there can only be a limited number of such networks and their ownership is a big issue.

Some companies not only own TV and radio networks but newspaper groups as well.Who decides what news to publish and what sort of “spin” to put on it? Is it always objective? There are now “spin doctors” who manipulate the news,emphasising certain parts and not others – and as a result, much of it is not neutral.Therefore, the question of control of the media matters very much.In some cases, the media companies are more powerful than governments.They can even influence elections.So the question is – should they be controlled and if so, by whom?

1.Immediate reporting has become possible all over the world because of().

A.reporters

B.the use of news networks

C.the use of satellites

D.the communications revolution

2.()has become the norm.

A.Electronic reports

B.Instant news

C.Live reporting

D.Transmitting images through mobile phones

3.In what ways are media companies powerful? ()

A.They can influence elections in some way

B.Nowadays, the manipulation of news reports is possible

C.They not only own TV and radio networks but newspaper groups as well

D.All of the above

4.According to the passage, the big issue is ().

A.ownership of news networks

B.that there can only be a limited number of such networks like BBC News 24

C.that networks owned by large companies and governments have become bigger and very powerful

D.that the news reporting is manipulated by big companies

5.What can be inferred from this passage? ().

A.The disadvantages of the communications revolution outweigh its advantages

B.We should put the question of control of the media on the agenda

C.The news reporting has always been objective

D.A reporter can send news directly to the audiences all over the world

第10题

Genetically-modified (GM) foodstuffs are here to stay.That’s not to say that food prod
uced by conventional agriculture will disappear, but simply that food-buying patterns will polarize: there will be a niche market for conventional foodstuffs just as there is for organic food.It may even be that GM food will become the food of preference because consumers come to appreciate the health benefits of reduced pesticide use.

Currently there are some 20,000 chemicals in use, but the scientists only have detailed information around 1,000 of them.To see the advantages of GM food you have only to consider the recent press revelation that the average lettuce receives eleven pesticide applications before it reaches the supermarket shelf.I’m sure chemicals and their role in disease will become a big issue in the 21st century as the population of the developed world worries increasingly about its health.

The reason GM food will not go away is that we need a three-fold increase in food production by the year 2050 to keep pace with the world’s predicted population growth to ten or eleven billion.It’s not just a question of more mouths to feed either.What is often forgotten is that all these extra people will take up space, reducing the overall land available for agriculture.

The world has 800 million hungry people.Until now, food supplies have been increased by improved varieties, pesticides and artificial fertilizers: the green revolution.Now we’re on the edge of a new one: a genetic revolution.

It may well be that in the long term it is the developing world that benefits most from GM food.It is true that for the next years or so GM crops may be too expensive.

6. According to the passage, food supplies have been increased by all the following except_____________.

A.pesticides

B.artificial fertilizers

C.improved varieties

D.transportation

7.How many chemicals are still less familiar to the scientists?()

A.20,000.

B.1,000

C.19,000

D.21,000.

8.Why will people prefer GM food in the future?()

A.Because it uses less pesticides.

B.Because it is much cheaper.

C.Because the production is increased.

D.Because it is organic food.

9.Which of the following is NOT true?()

A.By 2050, the world population will grow to ten or eleven billion.

B.In the 21st century, GM food will take the place of conventional food.

C.More and more people will reduce the overall land available for farming.

D.More and more people will consume more food and occupy more space.

10.The author’s attitude towards GM food is _______.

A.negative

B.positive

C.critical

D.uncertain

第11题

Impatience has been around for a long time.There is nothing new about people losing th
eir patience while stuck in traffic or waiting in line.But some experts believe that people are less patient today than in the past.

Some analysts suggest that in recent years many people are less patient because of technology.They suggest that “digital technology, from cellphones to emails to Wads, is changing our lives.The instant results we get from this technology have in turn increased our desire for instant satisfaction in other aspects of our lives.”

Psychologist Jennifer Hartstein makes some observations.She explains that “we have become an immediate satisfaction culture, and we expect things to move quickly, efficiently and in the way we want.When that doesn't happen, we tend to become increasingly frustrated and unsatisfied.”

Some believe that e-mail is losing popularity and could soon become outdated.Why? Because many people who send messages do not have the patience to wait hours, or even minutes, for a response.Also, with e-mails, as with letter writing, introductory and concluding greetings are often expected.But many people consider such formalities(客套)to be boring and time-consuming.They prefer instant messaging.Many people do not take the time to proofread what they put in writing.As a result, letters and e-mails contain numerous grammatical and spelling errors.

The thirst for immediate results is not limited to the digital communications.People seem to be losing their ability to wait in other areas of life.For instance, do you ever find yourself talking too fast, eating too fast, driving too fast, or spending money too fast? The few moments it takes to wait for an elevator to come, for a traffic light to change, or for a computer to start may seem like too long a time.

16.According to the first paragraph, people ______.

A.were more patient in the past

B.have been patient for a long time

C.used to be patient while stuck in traffic

D.used to be patient while waiting in line

17.Nowadays people lose their patience because().

A.their desire for satisfaction has increased

B.they are bored with what they have

C.they have more things to do than before

D.their life has been changed by technology

18.Some believe that e-mail could soon become outdated because ______.

A.it takes a long time to start the computer

B.people value formalities between friends

C.people can hardly wait for a response

D.cellphones are more popular nowadays

19.The pursuit of instant results causes people to ______ .

A.become more impolite

B.have more errors in their writings

C.use voice messages instead of emails

D.lose many of their abilities in life

20.The best title for the passage might be “______”.

A.What Are the Problems Caused by Impatience
