The power of nature

    There are some things in nature that we cannot stop from happening. We cannot stop the power of nature. A flood comes when there is too much water on the land. Sometimes， it is after a big storm when too much rain falls on the land. Sometimes it is after a big storm at sea， when too much sea water comes onto the land. The fast flood water can hurt us and can hurt our homes. We cannot stop a flood from coming， but we can try to stop the water from coming into our homes. We can try to stop the water by making a wall. We can use sandbags to make the wall.

    An earthquake comes when the land moves. The land goes up and down and in different directions. Then land can crack（断裂）. An earthquake can hurt us. We can get hurt by things that fall down in an earthquake. Falling things can start fires. We cannot stop an earthquake from coming， but we can try to make our homes strong so that they will not fall down in an earthquake.

    A tornado（龙卷风）is fast air that goes around and around over the land. A tornado can pick up anything. It can break anything that is in the way. A hurricane（飓风）is a big storm with fast winds and strong rain. It begins at the sea and can come onto the land. Its fast winds can hurt us and our homes. We cannot stop a tornado or a hurricane from coming， but we can get out of its way. We cannot stop the power of nature， but we can go to places where we can be safe.

To be a good tourist

    Nowadays, travelling is becoming an important part of our life. However, some people have bad habits when visiting places of interest.

    Some people often make loud noise that makes others feel uncomfortable. Some people don't realize the importance of protecting our environment. They throw rubbish everywhere. Some people like to take photos in wrong places, even in dangerous places. These are very rude and unwelcome in public.

    As a student, I think we should remember to do something to be a good tourist. First of all, we should throw rubbish in the dustbin instead of dropping it everywhere. Secondly, don't make too much noise, especially in some quiet places. It is not polite. Finally, we understand that many people like taking photos while travelling. It is fun. But we should take photos in proper places and always remember safety comes first.

    In a word, if all of us can try our best to be good tourists, I believe we can make a great difference to our environment and we can have more fun as well.

    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.
