Different weather makes people feel different. It influences health, intelligence(智力) and feelings.

    In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states(州) have more heart trouble after the weather changes in February or March.

    The weather can also influence intelligence. For example, in a 1983 report by scientists, IQ(智商) of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).

    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 unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18℃, people become stronger.

    Low air pressure(气压) may make people forgetful(健忘). People leave more bags on buses and in shops on low-pressure days. People feel best at a temperature of about 18℃.

    Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather's problem.

    Mary was ill yesterday. She went to see a doctor.

    "Doctor, I'm not feeling 1 at the moment," she said. "Every time I do my homework at night, I feel 2. If I walk to school, I have to sit down and 3  for ten minutes."

    The doctor looked 4 Mary carefully. At last he said, "5 serious, but I'm afraid you are 6 too much."

    "I don't understand. What do you mean?" asked Mary. "I mean you eat too much 7 ,"said the doctor.

    "Oh! You mean I'm too 8. That's a problem," said Mary. "What should I do if I don't want to be heavy?"

    "The answer is easy," said the doctor. "If you want to be thinner and healthier, you 9 eat a lot of food and you also should take more 10."

    Water is very important to us. Every day we drink water, cook with water, take a shower in water, and have many other activities with water. Let's read and learn more about it!

    70percent of an adult's body is water. And about 80percent of a baby's body is water.

    Drinking too much water q{#blank#}1{#/blank#} can cause water intoxication (醉).

People should have about eight c{#blank#}2{#/blank#} of water every day.

    By the time you feel thirsty, your body has l{#blank#}3{#/blank#} over one percent of its water.

    About 80percent of the Earth's surface is covered with water.

    Only one percent of this water is fresh, 97percent is salt water and two percent is f{#blank#}4{#/blank#} in glaciers (冰川).

    And now, it's time to s{#blank#}5{#/blank#} water!

    Life comes in a package. This package includes happiness and sadness, failure and success, hope and despair. Life is a learning process. Experiences in life teach us new lessons and make us a better person. With each passing day we learn to deal with various situations.

Love plays a main role in our life. Love makes you feel wanted. Without love a person could become cruel. In the early stage of our life, our parents are the ones who show us with love and care. They teach us about what is right and wrong, good and bad. But we don't always care about it. It is only after marriage and having kids that a person understands others' feelings.

Happiness can bring people a peaceful mind. No mind is happy without peace. Sadness is the cause of the death of a loved one or the failure. But all of these things will pass away.

Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows us a specific way. Success brings in money, pride and self-respect.

Hope is what keeps life going. Parents always hope their children will do well. Hope makes us dream. Hope builds in patience. Life teaches us not to despair even in the darkest hour, because after every night there is a day.

Life teaches us not to regret over yesterday, for it has passed and is out of our control. Tomorrow is unknown, for it could either be bright or dark. So the only choice is to work hard today, so that we will enjoy a better tomorrow.
