不要和陌生人说话 Don't Talk to Strangers

Before we go to school, we get our parents to supervise us all the time, so we live in a very safe environment. While when we go to school, parents can't keep their eyes on us all the time, they are so worried about us, so they begin to tell us how to keep ourselves safe. The most important thing is that don't talk to strangers, as a teenager, we haven't had the ability to judge who is the good guy and who is the bad guy, so it is better not to talk to the strangers. The bad guys will like to talk to the teenagers, they want to do something to pay the teenagers' attention, thus they can induce the children to go with them and do the bad thing. In order to protect teenagers' security, teenagers are taught to keep distant from the stranger.

在我们上学前，我们一直有父母的照看，所以我们生长在一个很安全的环境。然而当我们上学以后，父母不能一直监视着我们，他们很担心我们，因此他们开始教导我们如何保持自身的安全。最重要的事情就是不要和陌生人说话，作为一名青少年，我们还没有能力去判断好人和坏人，所以最好不要和陌生人讲话。坏人会喜欢和青少年聊天，他们想要做一些事情来吸引青少年的注意，以此来引诱青少年跟他们走，做坏事。为了保护青少年的安全，青少年应该和陌生人保持距离。

Physical fitness is today's hot topic. And everywhere you turn you hear something new. But is it all true?

The more you sweat, the more fat you burn .

This myth has encouraged people to work out in extreme heat or wear layers of clothes or rubber or plastic weight-loss suits in the hope of sweating fat off. Unfortunately, it's water they're losing, not fat.

Fat burns when it is used as a fuel source for exercise, which doesn't happen initially. When you first begin to exercise, you burn carbohydrates or sugars. It takes about 20 minutes of easy to moderate aerobic activity before the transition from burning sugars to fat begins. (Aerobic exercise is any rhythmic and continuous activity that uses oxygen and large muscle masses of the body, such as the arms and legs. Examples are bicycle riding, jumping rope, walking, jogging, aerobic dance, and swimming.) So, to burn the flab, plan on working out at least 40 minutes.

If you stop working out, your muscles will turn to fat.

If you decrease your activity and continue to eat the same or more, you may gain back that spare tire that you worked so hard to lose. It's not, however, because your muscles turned to fat. Muscles may atrophy or lose their tone, but they won't turn to fat. Muscle is muscle and fat is fat.
