Not very long ago, the question would have seemed absurd. Now it is on the lips of respected scientists; MPs are beginning to talk of "a war on sugar", and even England's chief medical officer has said sugar may have to be, like the old enemy tobacco, taxed in order to protect the nation's health. There came a time in the evolution of public attitudes to smoking, when the doctors had been shouting for long enough that the public was broadly aware of the risks and the only question left,for Government was: what should we do about it? Some believe we are now at the same point in our attitudes to sugar. Others - largely but not only representatives of the food and drink industry - say the entire debate has been skewed, by those who spread stories deliberately to make people nervous. More or less everyone agrees that eating too much sugar is bad for you. There is also no doubt obesity is a growing problem which is putting a significant, avoidable burden on the NHS by increasing the rates of diabetes, heart disease and other long-term conditions. But to what extent is sugar - rather than saturated fats, or salt, carbohydrates or proteins, or any of the other devils of modem diets - the cause of obesity and how much should we worry about it? Yesterday, hopes of achieving anything resembling clarity from the World Health Organisation (WHO) were confused once again, which, widely expected to reduce the recommended sugar intake by a half in new draft guidance, instead said it would continue to recommend that sugar make up no more than 10 per cent of the energy we consume, while adding that cutting this to five per cent would have "additional benefits". The decision will now go out to public consultation. Simon Capewell, professor of the University of Liverpool, said that he suspected "dirty work" on the part of food and drinks companies might lie behind the WHO's less than resounding message. "The food industry say Govemment has no business interfering in families, we must... Which of the following can be the proper title for the passage? A) Is sugar the new evil? B) How much sugar do you take daily? C) Is sugar to be taxed? D) How much do you know about sugar?

I'm a speed reader. Have been since I was a teen. Mother worked for the continuing education department of a university, and they were offering a class on speed reading and needed one more person to fill out the class. I became that one person. The class met for only an hour or two for a few weeks, but when the goal of a class is speed, you don't need to meet for long. The instructor said to make our eyes go across the lines of words as fast as they could and not to be concerned about what the words meant. I read Animal Farm in 10 ten minutes. Cover to cover. The instructor asked what the book was about. I said I didn't know, but if I had to guess I'd say it was about animals on a farm. He looked displeased. I've been speed reading ever since. I can't stop and I can't slow down. Today, for example, I plan on reading Churchill's History of the English Speaking Peoples over lunch. I hope it's more memorable than Animal Farm. As a result of all this speed-reading, I often experience a delay between what I think I read and what something actually says. The other day I passed by a mall with a large sign that said "Auto Theft Sale". I thought how efficient it was for auto thieves to simply sell all the stole cars in a big tent at the mall. A half-mile later it dawned on me that the sign had said "Auto Tent Sale". Every time I drive through a construction zone, I gasp . The sign says: "Hit a Worker $10, 000 (about 62,000 yuan)." It reads like they're offering a reward. Of course, it's not an offer. It's just that my eyes rarely take in the last line that says, "Fine." It's a $10, 000 fine if you hit a worker. Someone really needs to rephrase that one. Speed reading has bitten me on the backside more than once. Especially as a writer. Just ask any of my editors. What left the instructor unsatisfied in the class? A) It took the author ten minutes to complete Animal Farm. B) The author read fast but didn't get the main idea of the book. C) The class was only an hour or two for a few weeks. D) All the class actually failed to follow his advice.

Ques: Though "nanometer" is now a fashionable term all over the world,few people know exactly what it is.It has become a new favorite of manufacturers and sellers in recent years.Many "high-tech" products bearing the name "nano" have entered the market,bringing more mysterious feeling to surprised consumers. Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles or crystallites of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works? Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation of the application of nano technology into medicine. Ji(director Institute of Nanomedicine): A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water.When people drink it,it will produce no special effect on human body. Prof.Ji told the reporter,so far,the investigation of nano materials is still confined in the laboratory.No commercial micro products can be produced yet.With the present level of science and technology,the time of everyday goods age of daily use articles made of nanometer materials is still years away. The commodities labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material,which makes them _ . Prof.Ji explained that nano cup is a real cup.It can also be included in the list of nano products in a certain sense.But the nano cup has not... Which of the following shows the right relationship? A) nanometer<millimeter<micrometer<meter B) nanometer<micrometer<millimeter<meter C) micrometer<millimeter<nanometer<meter D) millimeter<micrometer<nanometer<meter
Ans: B
Ques:The fast development of modern technology has not only provided people with more income, but also enable them to enjoy long weekends and holidays. Never before have so many people traveled to so many different parts of the world and, with the help of fast, comfortable forms of modern transport, more and more people are tempted to leave their homes to see more of the world. It seems as if there are travelers everywhere. People travel because traveling benefits them in a number of ways. First, it enables them to get much pleasure from sight-seeing and photo-taking. Second, traveling makes them fully relaxed and ready to get back to work happily. Third, it offers them an opportunity to visit old friends and make new friends as well. Finally, it allows them to see different customs, learn new things, gain new experience and enables them to come back with a broader mind. With so many advantages to traveling, I think people should be encouraged to travel from time to time, especially on holidays, if their pocket and health permit. Traveling benefits people in _ ways A) 2 B) 3 C) 4 D) 5
