【题目】【改编】Can you believe everything that you read? It seems as if every day, some new articles come out about a new discovery about this or that. For example, water is bad for you, or good for you. The answer depends on which scientific study has just come out. People cannot decide which food items are healthy, how pyramids were constructed, and why dinosaurs disappeared. When we look for answers we sometimes can believe persuasive researches and scientists. But how trustworthy are they really? Here are two examples of scientific hoaxes.

As far back as 1726, Johann Beringer was fooled by his fellow scientists into thinking he had made an amazing discovery. The fossils of spiders, lizards, and even birds with the name of God written on them in Hebrew were unlike anything that had been found before. He wrote several papers on them and was famous for those only to have it revealed that they were planted by jealous colleagues to ruin his reputation.

When an early human being was discovered in 1912, scientists at this time were wild with excitement over the meaning it had for the theory of evolution. There were hundreds of papers about this Piltdown man over the next fifty years until it was finally discovered to be a complex hoax. The skull (头骨) of a man had been mixed with the jawbone of an orangutan (猩猩) to make the ape (猿) man.

The next time you read the exciting new findings of a study of the best scientist, do not automatically assume that it is true. Even qualified people can get it wrong. While we certainly should not ignore scientific research, we do need to take it with a grain of salt. Just because it is accepted as the truth today does not mean it will still be trustworthy tomorrow.

【题目】【原创】The spread of Western eating habits around the world is bad for human health and the environment. Those findings come from a new report in the journal Nature.

There are ways to solve this diet-health-environment problem. But they will require a change in eating habits. And what we eat can be a product of culture, personal taste, price and ease.

David Tilman , a professor of ecology, examined information from 100 countries to identify what people ate and how diet affected health and found as nations industrialized, population increased and earnings rose, more people began to adopt what has been called the Western diet.

The Western diet is high in refined or processed sugar, fat, oil and meat. By eating these foods, people began to get fatter -- and sicker.

David Tillman says overweight people are at greater risk for non-infectious diseases like diabetes, heart disease and some cancers.

Unfortunately when people become industrialized, if they adopt this Western diet, they are going to have these same health impacts, and in some cases if you are Asian, you have them more seriously than what happens in the West."

China, he says, is an example where the number of diabetes cases has jumped. And that’s happening all across the world, in Mexico, Nigeria and so on.

A diet bad for human beings is also bad for the environment. As the world's population grows, experts say more forests will become farmland for crops or grasslands for grazing cattle.

"We are likely to have more greenhouse gas released in the future from agriculture because of this dietary shift than all the greenhouse gas that comes out of cars, airplanes, boats and ships. So our change in diet is likely to be worse for the world for climate warming than all the transportation sources we use right now."

He says one possible solution is leaving the Western diet behind.

D. Raising more cattle.

【4】In which section of a newspaper can you find this passage?
