Rice is an important part of many people’s diets. Researchers from the Harvard School of Public Health in Massachusetts have released a report about rice. It shows that eating white rice increases the risk of type two diabetes. However, eating brown rice reduces the risk of the disease.

The World Health Organization says more than two hundred twenty million people worldwide have diabetes. Type two diabetes results when the body cannot effectively use the sugar it produces.

More than thirty-nine thousand men and one hundred fifty-seven thousand women took part in the study. They were asked about their diet and day-to-day activities, as well as any pre-existing diseases. The study found that the people who ate five or more servings of white rice per week had a seventeen percent increased risk of developing type two diabetes. But those who ate two or more servings of brown rice a week had an eleven percent reduced risk of getting the disease.

Brown rice is the grain in its natural form. White rice results after it has been refined. This involves removing the outer cover, including the husk, bran and germ. Only the inner white kernel is left. White rice is often enriched to replace some nutrients lost during the refining process.

Sun Qi is the lead writer of the report. He says the outer parts of brown rice slow down the work of the body’s digestive enzymes into starch. This means that the release of sugar into the bloodstream is slower after eating brown rice compared to white rice.

A diet of foods that quickly release sugar into the bloodstream has been linked with a greater risk of type two diabetes. The exact reason for this is not known.

Doctor Sun says less refined grains have more nutritional value than refined grains. He says replacing white rice with whole grains like whole wheat or barley could result in a thirty-six percent lower chance of developing type two diabetes. However, brown rice does not last as long as white rice because of the oil-rich layer of bran. This makes it less usable in poor communities.

He only finished fourth in this year's Super Boy talent show. But it didn't stop him capturing (俘获) the hearts of thousands of fans. He can hit high notes with ease. And he is very modest. Zhang Jie,25,shed(流) sweat and tears all the way through the competition, but he never gave up.

His life changed after he competed in My Show. He won first place and signed with a record company.“I was very excited and regarded it as a way to take me closer to my dream,” he said.

Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet ripe or finished. For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns(角) had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in battle. By the eighteenth century, a greenhorn had the meaning it has today—a person who is new in a job.

Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundreds. A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

The Green Revolution is the name given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural scientists who had green thumbs.

Green is also the color used to describe the powerful feeling, jealousy(嫉妒). The green-eyed monster is not a frightening creature from outer space. It is an expression used about four hundred years ago by British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling a person has when someone has something he wants. A young man may suffer from the green-eyed monster if his girlfriend begins going out with someone else. Or, that green-eyed monster may affect your friend if you get a pay rise and she does not.

2.A person who has a green thumb is a person ____.

A. who is good at growing plants B. whose thumbs are in green color
