Beijing had its biggest snowfall since 1951. Britain is suffering through its longest cold snap (寒潮) since 1981. And freezing weather is hitting the Deep South, including Florida’s orange groves and beaches.
Whatever happened to global warming?
Such weather doesn’t seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases. But experts say the cold snap doesn’t contradict global warming at all—it’s just a temporary phenomenon in the long-term heating trend. “It’s part of natural variability,” said Gerald Meehl, a senior scientist. With global warming, he said, “we’ll still have record cold temperatures. We’ll just have fewer of them.”
Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes. But experts did not connect the current cold snap to climate change.
So what is going on?
“We basically have seen just a big outbreak of Arctic air over populated areas of the Northern Hemisphere”, Arndt said.
In the atmosphere, large rivers of air travel roughly west to east around the globe between the Arctic and the tropics. This air flow acts like a fence to keep Arctic air restricted. But recently, this air flow has become bent into a zigzag (之字形) pattern, wandering north and south. If you live in a place where it brings air up from the south, you get warm weather. In fact, record highs were reported this week in Washington state and Alaska.
But in the eastern United States, like some other unlucky parts of the globe, Arctic air is coming from the north. And that’s how you get a temperature of 3 degrees in Beijing, a reading of minus-42 in mainland Norway, and 18 inches of snow in parts of Britain. The zigzag pattern arises naturally from time to time, but it is not clear why it’s so strong right now.
What is the best title of the text?
A. Freezing weather is hitting the Deep South.
B. We’ll still have record cold temperatures.
C. The air flow has become a zigzag pattern.
D. Cold snap doesn’t contradict global warming.
With global warming, we will ______.
A. also meet with severe cold snap
B. have more hot temperatures forever
C. never experience cold temperatures
D. have more cold temperatures
According to experts, the current cold snap ______.
A. suggests that the climate has changed greatly
B. is not related to the climate change
C. shows that the climate will turn cold
D. is affected by global warming
Beijing had its biggest snowfall since 1951 because of ______.
A. a fence from the Arctic B. a cooling trend in climate
C. a big outbreak of Arctic air D. its large population
We can conclude that ______.
A. not all the parts of the Northern Hemisphere are cold in face of the cold snap
B. the zigzag pattern arises naturally accidentally
C. Beijing will get cold weather next year
D. Washington state and Alaska will not face cold weather next year

Everyone knows you must exercise regularly to keep good health. Indeed, staying physically fit is a big part of our culture. we consider(or rightly so)that healthy people are attractive people. Since most of us want to be attractive, there is no shortage of exercise clubs, training videos, magazines and books offering to help us stay physically fit.
Unfortunately, however, our culture doesn’t place the same emphasis on mental fitness. Although we tend to like men and women with strong, healthy-looking bodies, we don’t have the same degree of respect or attraction for smart, educated, mentally healthy people. This is a pity, because there are great rewards for people who have developed the ability to think well.
If your mind is well trained and flexible, you will be able to understand a great deal of what happens around you. And if you are also well educated --- that is, if you understand basic science, mathematics, music, art, literature, history and so on --- you will find it much easier to make good decisions throughout your life. Over the long run, this leads to a sense of control over your destiny and a much better life than otherwise.
People who are poorly educated or who don’t think well --- that is, people who are not mentally fit --- see things differently. Their world is controlled by mysterious, often malevolent(惡意的)forces. Such people live within a system they will never master, forced to follow rules they will never understand. Although it may not be obvious, most spend their lives being manipulated(控制)by others. They are told what to do, what to think, how to spend their money, and what they should and should not aspire(渴望)to in life.
In my opinion, if you want to live well, you must be able to use your mind well. For this reason, I want you to be able to concentrate, to solve problems, to understand complex ideas, and to think clearly and quickly. Such skills will make it easier for you to make informed decisions, understand current events, choose good friends, manage your money well, make wise lone-term decisions and appreciate music, art and literature.
The key to developing such skills is to enjoy learning, and to have the ability and motivation to teach yourself.
63. The writer of the passage feel disappointed that ____.
A. too little has been done to help people to keep physically fit
B. too much has been done to help people to keep physically fit
C. mentally healthy people are not as popular as physically healthy people
D. physically healthy people are not as popular as mentally healthy people
64. The underlined word “this” in the 3rd paragraph means ____.
A. the understanding of a great deal of what goes on around you
B. the understanding of basic science and mathematics
C. good training in body and mind
D. being able to make good decisions in life
65. The writer of this passage thinks those who are not mentally fit ____.
A. live a poor and mysterious life B. can’t control over their life
C. often do what others do D. enjoy being fooled and ruled
66. The best title of the passage will most probably be ____.
A. Train Your Body B. Train Your Mind
C. Make Informed Decisions D. Think Hard and Work Hard

Many do-it-yourself homeowners are interested in
trying out solar power to leam about the technology and
perhaps to provide energy for limited-use applications.
There are a variety of ways to find cheap solar panels
(板), including buying used and building your own
with factory seconds.Both methods will save money
while forcing you to learn the ins-and-outs of a solar
power array (陣列).
We've all seen solar-powered street signs or PV
panels being used for various purposes at remote locations.
When those units become cracked or chipped and are considered "unsafe", companies are forced to replace them, generally to avoid responsibility issues.Because it's difficult to get rid of PV panels, many companies, if approached, are willing to give them away or to sell them for modest prices.Depending on the degree of damage present, expect to see performance degradation (降級(jí)) in the range of 10% to 60%.A multimeter (萬(wàn)用表) can be used to test the panel before buying.If the panel's free, take it anyway.It could still be useful in a home solar project.
A solar panel is really nothing but a box serving as a container for a large group of solar cells.Factory second solar cells are usually sold on eBay at a small part of their regular cost.The cells come in a variety of sizes.You will need to figure out how much power a single cell produces to determine how many will need to be wired together to form an array.
A simple search of the Internet will show numerous sites detailing home solar panel projects.Do-it-yourself lovers are generally quite generous in supply photographs of their work and description of what went wrong and right with the project.
Getting cheap solar panels with slight imperfections, either used or through sales of factory seconds, is a perfect solution for home-built renewable energy projects.The high number of solar lovers online provide a wealth of useful information.Only limited skills are required, plus an understanding of the basic wiring involved.All are well within the talents of almost any home handyman.Beyond the satisfaction of having completed the project, you'll come away with a functional solar panel that will be a source of power for use around the house or at remote locations.
Solar energy systems are quickly becoming more popular with homeowners as prices continue to decline.
72.The author writes the passage to introduce ____.
A.ways of finding cheap solar panels B.ways of saving energy
