Some insects, such as butterflies and ladybugs, are quite beautiful. But, did you know that many bugs are also edible and are filled with protein?

Aletheia Price knows this—and a lot more—about bugs. She also thinks you should try eating some. If you visit the website www.eatbug.com, you will find all kinds of information about edible insects. Most of it was written by Aletheia Price when she was fifteen years old. Aletheia started eating bugs at the age of thirteen. Before long, she found that she really enjoyed some of them. She also became interested in finding out more about which kinds of bugs could be eaten and how to cook them.

According to Aletheia, there are at least 1,462 kinds of edible insects. (Doesn’t that make you wonder who tried all of them and decided they were edible?) Some of her favorite dishes include mealworm chocolate chip cookies, ant tacos(玉米卷), and chocolate-covered crickets(蟋蟀). On her website she has recipes for insect entrees(开胃菜) and some helpful tips. For example, when preparing crickets, it is best to remove their legs before cooking, for the legs tend to get stuck in your teeth. She also offers information for anyone who wants to raise bugs for food.

Aletheia realizes that eating bugs is not for everyone. But, if you think about it, you have to admit that eating bugs might be a good idea. There are billions and billions of bugs in this world. If we could get used to eating them, we would have plenty of food for everyone.

1When Aletheia was 13, she _________.

A.wrote articles about bugs

B.ate bugs for the first time

【题目】 As e-cigarettes become more popular, fewer people are taking up smoking traditional cigarettes. But can e-cigarettes, an electronic nicotine delivery system, help people quit smoking altogether? The answer is probably yes. A study led by Matthew Carpenter, a professor at the Medical University of South Carolina found that e-smokers tend to smoke less and have increased quit attempts.

In the pilot study, Carpenter evaluated e-cigarettes in terms of usage, product preference, changes in smoking behaviors and nicotine exposure. Ninety subjects were evaluated45 were randomized to use e-cigarettes, and 45 were randomized to a control group. Everyone was followed over a period of four months. The study was published in Cancer Epidemiology in November and is one of the few randomized studies in the U. S. to examine the effects of e-cigarettes.

Results showed that when smokers were given e-cigarettes, uptake was strong. Many participants rated the e-cigarettes similar to their usual product, suggesting that e-cigarettes might give smokers a suitable alternative to combustible(燃烧的)cigarettes. E-cigarettes offer significantly less exposure to harmful toxicants and therefore are safer. People using e-cigarettes throughout the study smoked an average of 37 percent fewer cigarettes, as compared to those in the control group, showing a positive effect when making the switch and potentially serving as a tool to help smokers quit.

That's good news for Carpenter and his colleagues. Smoking is the leading cause of cancer and has a negative impact on the effectiveness of cancer treatments. People who quit smoking, regardless of their ages, have substantial gains in life expectancy(预期寿命)compared with those who continue to smoke.

Carpenter cautions that while e-cigarettes may help people smoke less or even quit, they are not for everyone. "It is important to protect non-smokers, particularly adolescents, from starting any nicotine-containing product. "

More than 1,500 varieties of e-cigarettes are now available, including different looks, high-tech power settings and many flavors. All these make them more appealing to kids. In fact, e-cigarettes are more popular than conventional cigarettes among youth. "All these should raise our alarm bells," he said.

E-cigarettes were only recently regulated by the Food and Drug Administration. Largely manufactured overseas, the quality control process varies, he says. Without enough information to answer the long-term public health issues of e-cigarettes, researchers like Carpenter are aware of the importance of further studies on the latest tobacco trends. Combustible cigarettes have been around for many decades. E-cigarettes have not, and the science has a lot of questions left to answer, he said.

1Which of the following is TRUE about Professor Carpenter's experiment on e-cigarettes?

A. The test groups include conventional smokers, e-smokers and non-smokers.

B. E-cigarettes expose smokers to fewer poisonous substances.

C. Many participants don't think e-cigarettes as good as traditional ones.

D. It is one of the few studies to test the effects of smoking.

2After reading the passage, we may infer that_______.

A. most e-cigarette smokers will finally give up smoking

B. there are more e-smokers than traditional smokes in the USA

3What can be concluded from the last paragraph?

A. E-cigarettes are faced with many problems and need more study.

B. The U. S. government should strengthen its regulation over e-cigarettes.

C. Smokers should be cautious because of e-cigarettes' low quality.

D. Researchers are concerned about e-cigarettes' harm to people's health.
