China’s economic growth “hard to predict”
The worsening global economic situation makes it difficult for China to predict its growth for next year, a senior official said on Friday.
“How fast China’s economy will grow next year is uncertain,” Liu He, deputy director of the Office of the Central Leading Group on Finance and Economy Work, told China Daily.
“To a large extent, the rate will be decided by the external(外部) situation,” Liu said during a discussion with Swedish Prime Minister Fredrik Reinfeldt and other economists in Beijing.
“This year, GDP is estimated to grow at 9.4 or 9.5 percent, down from 10.6 percent last year,” he said. “However, the impact of the current financial turbulence on our economy is much less than on the rest of the world.”
Nicholas Stern, a former UK government advisor, also told China Daily it will take at least one or two years for the world to recover from the recession, which is now spreading from the US and the UK to the rest of the world.
“We don’t know how long the recession will last, but it is unlikely to be short,” he said.
Liu said China can use the downturn(衰退) as an opportunity to restructure its economy, which has relied heavily on government investment, foreign trade and low-cost technology over the past years.
“When the economy is experiencing fast growth, companies are unwilling to upgrade their technologies,” Liu said.
“The slowdown gives such firms the opportunity to enhance(提高) their competitive edge through better technologies.”
(From China Daily 2009-01-11)

It is the season for long lines and frayed(紧张的) nerves. Here are some ways to survive a holiday flight.
Lighten up
Do yourself a favor and ship your presents. Nearly every US airline charges a fee to check a bag, so shipping gifts is now cheaper and more convenient than carrying them in your luggage.
Weigh your options
Not knowing what you’re going to pay for your luggage is annoying. So calculate your overweight-luggage fees at home. You can find the fees out in advance by visiting new site Luggage Limits, which provides the latest information on more than 90 airlines.
Leave amateurs in the dust
Trust us and get to the airport an extra half-hour early. The check-in and security lines are filled with inexperienced files, and it’s a hard walking. Plus, if you decide to cut it close you may not get onto the flight at all. To reduce costs, airlines have reduced on flights and routes. The remaining flights are more likely to be oversold, especially on busy travel days. Fliers who check in early are the least likely to get bumped from oversold flights.
Take it public
The rates for renting a car at the airport have more than doubled over the past year because rental lot inventories have decreased dramatically(现住地). True, renting at the airport is convenient, but it’s just not worth it anymore. Unless you really need a car, take public transportation, hop a cab, or beg a friend to pick you up at the airport instead.
Say no to bumper cars
Tell the people picking you up to avoid parking their car. They can hang out in their car for free while waiting to get a call from you when you land. Many airports, including JFK and LAX now feature this sensible choice.
【小题1】How does the author think of shipping gifts?

【小题2】Airlines have reduced flights to _________.

A．deal with crisis	B．reduce the time for leave
C．lower the cost	D．provide more job chances

【小题3】 It can be learned from the passage that ______.

A．renting a car at the airport is expensive	B．taxis stay at the airport free of charge
C．cars can park at the airport for free	D．JFK encourages people to take a taxi

【小题4】 What’s the best title for the passage?

A．Five ways to survive a holiday flight.	B．Good seasons for flight.
C．Cars at the airport.	D．How to board a flight

Something big is happening to the human race, something that could be called the Great Transformation.
The Transformation consists of all the changes that are occurring in human life due to advancing technology. For thousands of years such progress occurred slowly. Now everything is changing so fast that you may find yourself wondering where all this progress is really leading.
Nobody knows what all these changes will really mean in the long run. But this mysterious Transformation is the biggest story of all times. It is the story of the human race itself.
Some people worry about what will happen when the deposits(蕴藏)of petroleum are gone, but already researchers are finding all kinds of new ways to get energy. Someday, solar power collected by satellites circling the earth or fission(裂变) power produced by mankind may give us all the energy we need for an expanding civilization(文明).Space exploraton promises to open up much new land for human settlement, as well as leading to the harvest of mineral resources.
Like it or not, our advancing technology has made us masters of the earth. We not only control all the other animals, but also reshape the world’s plant life and even its soil and rocks, its waters and surrounding air.
Technology gives us the power to build a great new civilizaion, if we can just agee on what we want it to be, bu today, there is little global agreement on goals and how we should achieve them.
So it remanins to be seen what will happen as a result of our technology. Pessimists(悲观主义者) worry that we will use the technology eventually to blow ourselves up. But they have been saying that for decades, and so far we have escaped. Whether we will continue to do so remains unknown, but we can continue to hope.
68.The Great Transformation is caused by ________.
A. changes in human life    B.the development of science and technology
C. space exploration        D. unknown reasons
69.Today it is impossible for people to build a remarkable new civilization because __________. A.nobody is optimistic about the future
B.human beings aare unabale to do so
C.people diagree with each other in many ways
D.people are worried too much
70.Advancing technology could possibly make us_______.
A.hesitate    B.decisive      C.powerless      D.mysterious
