问题 材料题

概括下面一段文字的主要内容,不超过30个字。

        目前,全球电子商务的发展潜力惊人,而 法律监管尚存在许多空白,尤其是如何规范跨国界网上交易,成为电子商务发展的严峻问题,美国和欧盟目前除加强内部立法外,正在加强沟通,力求建立一种为世界各国和地区接受的电子商务游戏规则。但是美欧之间的利益和文化差异,不可避免地导致他们在商务立法和监管方面的 差别 。如不久前,法国一位法官命令美国雅虎公司设法阻止法国用户在雅虎拍卖网站购买纳粹纪念品。雅虎公司则认为这种要求在技术上是不可能实现的。在跨国界网上交易中,究竟是以销售者所在国的法律为准,还是以购买者所在国的法律为准,引起美、法人士的不同意见。另外,美欧双方对“隐私”和“电子签名”等电子商务中基本问题的要求也都不尽相同。所有这些,造成国际电子商务屡屡出现争端。

     Among the most popular forms of dieting is the South Beach diet, developed by Arthur Agatston

of Miami, Florida. Dr. Agatston developed the South Beach diet for his patients with heart problems

to lose weight. Since weight matters a lot in keeping heart healthy and traditional low-fat diets were too

difficult for them to stick to, Dr. Agatston decided to create a plan that could help his patients. At first,

the diet was just for his patients. Soon, thanks to his patients' success, the diet became the buzz in

Miami, and eventually, word spread across the nation.

     This diet focuses on a healthy balance between carbohydrates (碳水化合物) and fats. It is based

on eating a combination of "good" carbohydrates and fats, while limiting those "bad" ones. It is divided

into three different phases.

     The first phase lasts for two weeks and is the strictest of the three. During this phase, you are asked

to restrict (限制) all carbohydrates (good and bad). You are allowed to eat all types of fish, cheeses,

eggs, and nuts, and a large number of vegetables. Most dieters can expect to lose between 8 and 12

pounds during this phase.

     During Phase 2, you are allowed to reintroduce some of those carbohydrates that are not allowed

before. You are encouraged to start eating carbohydrates that have a low glycemic index (升糖指数).

But you should keep in mind that the key is moderation (适度). Most people continue to lose 1-2

pounds per week. You continue with this phase until you reach your target weight.

     Phase 3 is designed to help you keep your weight. During Phase 3, you can reintroduce some of

the carbohydrates that have a higher glycemic index, although again, this should be in moderation. Phase

3 is meant to be a way of life.
