生产经营单位应当向从业人员如实告知作业场所和工作岗位存在（）、防范措施以及事故应急措

As a girl, I've spent a great deal of my time on earth concerned about my weight. So I do know something about exercise. Let me tell you about the calorie-burning activities I've tried or will try.

Salsa (萨尔萨舞)

I try to maintain my weight through dancing. Dancing improves my coordination and sense of rhythm in addition to burning calories. I'm personally interested in salsa, which I find sexy and expressive(有表现力的). But I have not yet to start classes, because classes are very expensive, and I cannot find a dance partner.

Ping-Pong

Ping-pong is the national sport of China, so how could I know nothing about it?

My father is a ping-pong fan, and a really good player. He's won several informal (非正式的) matches. My relationship with ping-pong has always been on-and-off. I'll get into it for a while, and then lose interest. The reason is because I can’t find a good partner. Some stronger can depress you, while someone weaker (or just as weak) can make the game boring.

Tae Kwon Do （跆拳道）

I've recently decided to try tae kwon do as my regular exercise activity. There’s a story behind this choice: A few weeks ago, I was sitting on a bus, concentrating on a book. Suddenly, the bus became very quiet except for the sound of a woman’s crying. I looked up to see what had happened and overheard whispers that she had just quarreled with a man, and the man slapped(拍打) her face. No one on the bus dared say anything because the man looked really strong. Even now I feel ashamed I was among the silent.

That’s why I've made up my mind to learn something that will help me protect others and myself.

Science Daily—Kids may roll their eyes when their mothers asks them about their school day, but answering her may actually help them learn. New research from Vanderbilt University reveals that children learn the solution to a problem best when they explain it to their mom.

“We knew that children learn well with their moms or with a peer, but we did not know if that was because they were getting feedback and help,” Bethany Rittle-Johnson, the study’s lead author and assistant professor of psychology at Vanderbilt’s Peabody College of education and human development, said. “In this study, we just had the children’s mothers listen, without providing any assistance. We’ve found that by simply listening, a mother helps her child learn.”

Rittle-Johnson believes the new finding can help parents better assist their children with their schoolwork, even when they are not sure of the answer themselves. Although the researchers used children and their mothers in the study, they believe the same results will hold true whether the person is the child’s father, grandparent, or other familiar persons.

“The basic idea is that it is really effective to try to get kids to explain things themselves instead of just telling them the answer,” she said. “Explaining their reasoning, to a parent or perhaps to other people they know, will help them understand the problem and apply what they have learned to other situations. We saw that this simple act of listening by mom made a difference in the quality of the child’s explanations and how well they could solve more difficult problems later on.
