Weather has a strong effect(影响) on people. It influences health, influences health(智力), and feelings.

    In August, it is very hot and wet in the southern part of the United States. Southerners have heart trouble and other kinds of health problems during this month. In the northeast and the Middle West, it is very hot at times and very cold at other time. People in these states tend to(趋向) have heart trouble after the weather changes in February or March.

    The weather can also influence intelligence. For example, in a 1983 study by scientists, the IQ scores of a group of college students were very high during a hurricane(飓风), but after the storm their scores dropped 10%. Storm can increase intelligence. Very hot weather, on the other hand, can lower(降低) it. Students in many schools of the United States often do badly on exams in the hot months of the year.

    Weather also has a strong influence on people's feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel sad during cold weather. In hot summer weather, on the other hand, fat people may feel unhappy. At about 18℃, people become stronger.

    Are you feeling sick, sad, tired, forgetful（健忘）, or very intelligent today? The weather may be the reason.

    Students spend more time at school than anywhere else. At school, children need a safe and comfortable environment to help them learn. By doing the following, parents can help make sure children have a good school life.

    {#blank#}1{#/blank#}. Ask your children if they see anyone bullied(被欺负), if they are bullied, or if anything else makes them feel uncomfortable. Look for warning signs, such as a sudden drop in grades or a loss of friends.

    {#blank#}2{#/blank#}. Tell children that fighting could lead to them getting hurt, or hurting someone else. Tell them about other ways they can solve a problem, such as walking away or telling to teachers or the adult you know well.

    {#blank#}3{#/blank#}. Talk to your children about what they do online—what websites they visit, who they email, and who they chat with. Let them know they can talk to you if anything they see online makes them uncomfortable.

    {#blank#}4{#/blank#}. Teach children to follow traffic lights and rules when walking or biking. Stress that they should cross the street at crosswalks.

    {#blank#}5{#/blank#}. Don't go anywhere with them, or accept gifts from them when you don't know. If they see a stranger hanging around or in their school, they should tell the people that you know.

    As Grade Nine students, we are as busy as bees. Every day we have to spend a lot of time finishing our homework, so we don't have much time to do sports. However, almost all the students realize the importance of exercise. We still try to spare time(课余时间) to do sports after school.

    Tom (a 15-year-old boy from Class 9)

    Doing sports is part of my life. As soon as the bell of the last class rings every day, I will be excited and rush out of the classroom to play football with my classmates in the football field. Playing football can help me keep healthy and always make me energetic(精力充沛的). In this way I can learn better later on.

    Lucy (a 14-year-old girl from Class 6)

    Rope skipping(跳绳) is my favorite sport. I often do it with my sister Lily. We want to take part in the school rope skipping competition(竞赛). So we practice it again and again so as to win the competition.

    Jim (a 16-year-old boy from Class 2)

My dream is to be a professional runner. I usually train hard every day so that I can make my dream come true. Sometimes my parents are not happy. They say I spend too much time in running. But I never go running during the class. I do it after school. I don't think it has any bad effects on my study.

    Robots were something in science novels and movies. Now there are many robots working in factories. In fact, most working robots are not like humans at all, some are more like strange machines. They do most of dirty or dangerous jobs over and over again. Robots never get bored or tired but humans will if they do the same jobs. Scientists believe there will be more new robots everywhere, but it may take hundreds of years. They will have different shapes. They will look like humans or animals. In India, scientists made robots that look like snakes. They can help find people inside fallen buildings.

    A few days ago, I ran into a stranger as he passed by. I said sorry to him and he said, "Excuse me, too, I wasn't even watching for you." We were very polite this stranger and I. Then we went on our way after saying goodbye.

    Later in the kitchen at home, as I cooked our meal, my daughter Betty walked up to me, very quietly. When I turned around. I nearly knocked her down. "Get out of the way!" I shouted angrily. She ran away, crying.

    That night, when I lay in bed, my husband said to me, "You were so rude to Betty. Go and look around on the kitchen floor, and you'll find some flowers there. Betty brought those for you. She picked them herself - pink, yellow, and your favourite blue."

    When I heard this, I thought deeply: While meeting with a stranger, I was calm and polite; but with my daughter, I was not patient. I felt sad and tears began to fall.

    I quietly went to Betty's bed, "Wake up, my dear," I said, "Are these the flowers you picked for me?" She smiled, "I found them by the tree. I knew you'd like them, especially the blue." I said, "I am so sorry that I treated（对待）you that way today." And she whispered（悄声说）, "Mommy, that's okay - I still love you anyway." I kissed her and said, "I love you too and I do love the flowers."

    That day Betty gave me a lesson on how to get along with each other in the family. I spent much time on work before and didn't realize how important family life was. I decided to change myself in the future.
