1 . Is It Worth Buying Organic Food?
Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.
The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”
For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.
While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.
Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

2 . The Silk Road is the name of different roads that long ago connected Europe, Africa and Asia. People reached these different places along these roads. Scientists believe people began to travel the Silk Road about 3000 years ago. By the time the Chinese silk trade became important in the world, the Silk Road covered almost 6500 kilometers. It spread from Rome to China, which is from the West to the Far East.
Traders travelling along the Silk Road carried silk, of course. They also carried and traded spices (香料), cloth, valuable stones and gold.
There is a famous old story along the old road. It is said that Roman soldiers travelled through central Asia. They started to live somewhere near the ancient Chinese village of Liqian. Sortie of these Romans married local Chinese women and the story of blue-eyed villages of China was started.
During its busiest period, the Silk Road allowed people from many different cultures and countries to meet each other and mix. The Silk Road allowed the sharing of valuable goods and new ideas. These included people and trading goods from the Mediterranean, Persian, Magyar, Armenian, Bactrian, Indian and Chinese areas. All these peoples travelled the Silk Road, and they shared goods, stories, languages, and cultures.
In modern times, the old Silk Road routes (路线) are still used, but now they are crossed by trains instead of camels and horses. There is even a Silk Route Museum in Jiuquan in China. It has over 35,000, objects from all along the Silk Road. In this way, China protects the history of many countries and peoples.
