Does stress cause gray hair？Many people believe that tension and stress can cause your hair to lose its color.In fact，it is an_old_wives’_tale that being upset all the time can result in premature graying.Here is a closer look at this situation and why some believe that this old wives’ tale could be true.
As one ages，the hairs on the head also age.In fact，just about everything on the human body begins to show signs of wear and tear after a while.The joints wear and become stiff and skin wears and becomes wrinkled.Hairs on the head grow and eventually die.They are replaced，but in the process something else happens.
When new hairs are replaced，the color or pigment (色素) is also added to them.However，as one ages，this pigment becomes less and less available.At first，hairs will have a limited amount of pigment and they will appear to be grayish in color.In time，they will lose all of their pigment and will be white.Many things are known to cause graying，and genetics is a very powerful factor.If one of your parents turns gray at an early age，there is a good chance that you will too.Some people begin the graying process in high school，while others may be over the age of forty.
Constant worry and tension can have many harmful effects on the human body.It is a known fact that stressful times can cause one to suffer hair loss.It would make sense that if it can cause these problems，perhaps it also may contribute to graying.However，there is no sound evidence to support this.
On the other hand，many medical professionals believe that there may be a link between graying and a constant state of anxiety or tension.Does stress cause gray hair？There is no scientific evidence to support the theory，but it is best to avoid stressful situations.

阅读下列短文，从每题所给的A.B.C和D项中，选出最佳选项。
Chocolate soap is supposed to be good for the skin. But it’s not so good for the tongue. Unfortunately for the US soldiers of World War II, the chocolate bars the army gave them tasted like they were intended for use in the bath.
In the army’s defense, it wasn’t trying to win any cooking awards. In fact, it specifically ordered that its chocolate bars not be too delicious, so soldiers wouldn’t eat them too quickly. These bars were created for survival, not taste. “They were awful,” John Otto, a former army captain in World War II said. “They were big, thick things, and they weren’t any good. I tried ’em, but I had to be awful hungry after I tried them once.”
As unappealing as the chocolate bars were to some, others liked them. Samuel Hinkle, the chemist who created the chocolate bars, pointed out that the number of bars made were far greater than the army needed. “It soon became obvious that the generous American soldiers were sharing their valued possessions with their foreign friends, whether soldiers of other countries or local citizens.”
The bars turned many hungry Europeans into friends of the United States. “People wanted them,” said Otto. “You’d give them to kids. In some places they were very hungry. And they sure helped relax people about American soldiers.”
Otto said he never saw a European turn his or her nose up at the chocolate. “It was food,” he said. “At that time, everyone was very hungry. I saw German kids standing outside the U.S. army kitchen. They weren’t begging, just standing there very politely. When we were done, the kids would eat the food out of the garbage. They were that hungry.”
Other Europeans did not see chocolate until well after the war ended. “We didn’t
