    A study shows that one million lives might be saved each year if people wash their hands with soap(肥皂) often. It also says that hand-washing with soap could be among the best ways to reduce diseases. Doctors say many diseases can be prevented from spreading by hand-washing. These include the common cold, influenza(流行感冒), hepatitis(肝炎), infectious diarrhea(腹泻) and so on.

    Doctors say you are easy to catch a cold by touching your nose or eyes after someone nearby has sneezed or coughed. Another reason to catch a disease is to eat food prepared by someone whose hands were not clean.

    They also say that hand-washing is especially important before and after preparing food, before eating and after using the toilet, after touching money and sneezing or coughing. The most helpful way is to wash them together while using soap and warm water. You do not have to use special soap. Be sure to wash all areas of the hands for about ten to fifteen seconds.

    Have you ever tried to hide your emotions (情感)from someone during a conversation? {#blank#}1{#/blank#}

    Scientists from the Ohio State University have found that people are able to tell other people's emotions according to changes in the color of their faces.

    Scientists studied pictures of people's facial expressions. {#blank#}2{#/blank#} For example, happiness makes our faces red around the cheeks and a little blue around the chin. Disgust(厌恶)creates not only a blue-yellow color around the lips, but also a red- green color around the nose and forehead.

    “We believe these color patterns are the result of small changes in blood flow triggered(触发) by the central nervous(神经) system." Lead researcher Alex Martinez said.

    {#blank#}3{#/blank#} Does the color alone or also facial expressions help people tell other's emotions?

    To figure this out, scientists added color patterns to pictures of faces that showed no facial expressions. {#blank#}4{#/blank#}They were able to tell the emotions 75 percent of the timewithout any difficulty.{#blank#}5{#/blank#} For example, when two people are heatedly arguing over something, we say they are red in the face. When a person is very angry, we'd say he or she is blue in the face.
