Crossing your legs is an extremely common habit; most people don’t even notice that they’re doing it when they sit down. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. This causes your body to increase your blood pressure to push the blood back to the heart.
Crossing your legs can also lead to neck and back pain. When you sit with your legs crossed, your hips are in a twisted position, which can cause one of your pelvic (骨盆的) bones to rotate. Since your pelvic bone supports your neck and spine, this can cause pressure on your lower and middle back and neck.
You also might notice that when you sit with your legs crossed for long periods of time, your feet and legs get tingly or have the feeling of being asleep. This is because when one leg sits on top of the other, it causes pressure on the veins (血管) and nerves in your legs and feet. It can cause numbness and/or temporary paralysis in the legs, ankles, or feet.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.

Since an early age, I have been told to be kind to others. One day I was in line at our local post office. Behind me stood a man, which coat was dirty and ragged. It was clearly that he hadn’t bathed or change his clothes for a long time. Hardly had he come in that the others stood back several foot away from him. In fact, I didn’t notice her at first. After I had my business finishing, I turned back to see what had been taken place. Turning to leave, I said to him, “Wish you nice day!” The man nodded, a big smile in his face.

If you have ever been in a school play or even made to believe you were a doctor, a detective, or a space traveler, you know the enjoyment that acting brings. Almost all of us have the wish to play the part of someone — or something else.1.
In the ancient world, acting was often connected with religious ceremonies and other special occasions. As far back as 2200 B.C., trained Chinese actors performed ceremonial dances in costume and makeup at harvest festivals. 2. The imitation (模仿) of movements and gestures was gradually added to the dance, as well as the wearing of masks, the singing of chants, and finally the use of dialogue.
While acting was coming into its own in the ancient Chinese classical theatre, it was doing the same in the western world, in Greece. From about 500 B.C. on, acting became a highly specialized art in Greece. Greek actors, however, still wore masks, and their motions (动作) were largely fixed by custom. 3.
Modern acting, by contrast, gives the individual actor great opportunity to develop his or her personal talents for serious, comic, or musical drama. The names, faces, and styles of famous movie actors are known worldwide. 4. A special form of acting takes place in radio drama, which was highly popular before television. In radio drama the actors face a unique challenge. They are unseen by their audience. So they must rely on voice alone to make their characters real to the listeners.
5. Only forty percent of Broadway actors are employed, most of them for only part of the year. Those who become stars need not only talent, but determination. They must not be easily discouraged. Otherwise, they might give up before the opportunity for fame presents itself.
A. The origins of acting are in the act of remembering.
B. Drama in Greece began with festivals honoring Dionysus.
C. It is believed that this was the first step in the development of acting.
D. Historical records indicate that this desire is as old as civilization itself.
E. Acting is not, as many people think, a quick, easy road to fame and riches.
F. Broadway and television provide other stages on which actors can display their talent.
G. Consequently, they had little opportunity to display their individual personalities.
