     Different weather makes people feel different. It influences (影响) 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 every cold at other times. People in these states 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 students were very high when a very strong wind came, but after the strong wind, their IQ was 10%

below. The wind can help people have more intelligence. Very hot weather, on the other hand (另一方面),

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 18C, people become stronger. 　

 　Low air pressure (气压) may make people forgetful. People leave more bags on buses and in shops

on low-pressure days. There are a  "good weather" for word and health. People feel best at a temperature

of about 18 centigrade (摄氏度). 　　

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

A few years ago, when I was still in high school, I met a wonderful and warm teacher. At that time in my life, there were many changes to adjust to, apart from the usual teenage troubles. My parents had divorced, so my elder brother and I had chosen to stay with my dad. Due to the fact that he was keeping the house, we didn’t have to move.

During this time, my teacher took a special interest in me. Being my English teacher, she encouraged my mind to travel to creativity I had long given up. She brought me out of the shell I built.

She became my mother, my older sister, my friend and my teacher. The one thing she couldn’t do though was to make me more girly as growing up with only my dad and brother made me a real tomboy.

Sometimes, I would be really immature（不成熟的）, especially if she was scoring me less than others on purpose. She knew I could do better than what I was handing in and so pushed me to extend further than limits.

When I finished school and then after college I was about to leave my hometowns she gifted me a watch that every second, with my pulse, should remind me of the one person who will forever wait and love me without reservation.

Time has passed and our friendship is distant, but in my heart, soul and mind, she is the closest I ever got.
