Generally, the amount of energy coming in is equal to the amount of energy going out. So, we say the earth’s energy budget is balanced. If more energy was coming in than was going out, the earth’s temperature would increase. On the other hand, if too much energy is thrown back, and not taken in, we would see the earth’s temperature dropping.
Of all of the sun’s energy that hits the earth, about 67% is taken in by the land, oceans, air and clouds and about 33% is thrown back into space.
小题1:The picture above shows us how ________ hits the earth.
A. the high temperature B. the heavy rain C. the sun’s energy
小题2:In the 2nd paragraph, the underlined phrase “equal to ” means “______”.
A. less than B. the same as C. more than
小题3:Picture ______ shows us the main idea of the last paragraph.
A. B. C.
小题4:If too much energy is thrown back, we will feel ______on the earth.
A. cold B. hot C. warm
小题5:The amount of energy that is _______ influences the temperatures.
A. well balanced
B. thrown back
C. taken in
答案
小题1:C
小题2:B
小题3:B
小题4:A
小题5:C
解析
试题分析:本文介绍的是太阳传递给我们能量,地球接受太阳的能量。如果地球吸收的能量越少,返回的能量越多的话,地球的温度就会降低。这就是太阳和地球之间能量的关系。
小题1:细节理解题。根据原文The sun gives energy and the earth receives the sun’s energy.及观察图片可知,是太阳能量撞击地球。故选C。
小题2:细节理解题。less than少于,the same as同样的,more than超过,equal to意为:等于,故选B。
小题3:细节理解题。根据原文最后一段Of all of the sun’s energy that hits the earth, about 67% is taken in by the land, oceans, air and clouds and about 33% is thrown back into space. 可知太阳能量的百分之六十七被陆地,海洋等吸收,剩余的百分之三十三被返回空间。故选B。
小题4:细节理解题。根据原文if too much energy is thrown back, and not taken in, we would see the earth’s temperature dropping.可知如果太多的能量被返回,我们将会感到地球温度下降。故选A。
小题5:细节理解题。通过阅读原文可知太阳能量被地球吸收的数量会影响温度。故选C。

Mistakes choosing food
University kitchens serve(供应) many kinds of food. Some students choose unhealthy food, because now their patents are not nearby to help them choose. Some students visit the kitchen many times while studying. Late at night, some students get harmful fast food such as fish and chips with Coke to drink. Students also have less time for walking, running, and doing sports because of their schoolwork.
Eating right
If you’re careful, you don’t have to add fifteen pounds. Here are some ideas:
Think more about what you eat.
Eat plenty of vegetables and healthy meats.
Don’t eat desserts full of sugar; have fruit after dinner.
Try not to eat so much unhealthy food while you study.
It’s all right to have a little fast food sometimes---but not often.
Write down the foods you eat.
Walk, run, do sports---move and you will feel better!
Remember that the “freshman fifteen” can happen to anyone. Talk to your friends about it. Together, try to eat healthy food and not to eat unhealthy food. Walking, running, and playing sports is always more fun with friends. Help each other and you can have a healthy and happy freshman year.

People often say they feel good when the sun is shining and sad when it is cloudy.In fact, sunlight makes us feel good.When sunlight hits our skins,our bodies produce a vitamin. Vitamins are natural chemicals(化学物质)which we all need to stay healthy.Sunlight helps our bodies produce vitamin D.Vitamin D helps our bodies make a special chemical.This special chemical affects our brains(大脑)and makes us feel happy.For example, there are long, dark winters of little sunlight in Sweden and Norway,so many peple in these countries often feel sad.Without much sunlight, their bodies produce less vitamin D.Without enough vitamin D, their bodies make less of this special chemical which makes them feel good.To help the people in these countries feel better,special “sunrooms”with artificial(人造的)lights have been built.People can go there and get “sunlight”for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.
小题1:Which of the following is NOT mentioned as a factor (因素) that can affect one’s emotions?
A.Weather. | B.Actions of others. |
C.Personality. | D.Age. |
A.It is a kind of artificial chemical. |
B.It makes us worried by affecting our brains. |
C.It is needed by us all to keep fit. |
D.It is in the sunlight. |
A.We feel good when we are in the bright cool weather. |
B.We will be happy when we are caught in the rain. |
C.All people in Norway and Sweden feel sad in winter. |
D.The more vitamin D you have, the happier you’ll be. |
A. Why Do We Feel Sad?
B. The Weather Influences People’s Emotions.
C. People Need More Vitamin D.
D. We Can Hardly Change the Weather.
Respect your teachers.First of all, students should respect the teachers. You should your teachers in the classes. That means to give your respect to him, to stand from your chairs when the teacher enters the classroom, etc. Attend any class attentively. In class of a certain subject or a teacher you don’t like very much, if it is totally anarchy(无政府状态), how can we talk about respect?
Play by the .
If your teacher wants you to take notes in class, do it. If she tells you to sharpen your pencils only before class starts, listen to her. If she late homework, do yours on time. Sometimes classroom rules seem strict or even silly, but most teachers know what’s necessary to make things run well and what it takes to let the learning begin. And the better the learning environment, the you will be!
Expect him/her to like you.
Teachers are teachers because they like kids. Given the chance, most teachers want to be your , too. Respect your teacher, but do not be afraid of him/her. He/ she wants you to have a great school year just as much as you want to have one!
Put first things first.
Friends are a fun part of school. But they are not the most important part. When your teacher is teaching, give him/her full attention, when it’s hard to do. Class will end and the ten-minute break will come soon enough, and that’s the time for playing with your friends

The professor went to the kitchen and returned a pot of coffee and all kinds of cups-crystal(水晶的), glass, plastic, some nice looking, some plain looking, some , some cheap. And he told them to help to the coffee. When all the students had a cup of coffee in hand, the professor said, "I"ve noticed that all the nice looking expensive cups were , leaving behind the plain and cheap ones. While it is for you to take only the best for yourselves, that is the root of your and stress. You know that the cup itself adds no quality to the coffee. you really wanted was coffee, not the cup, you consciously went for the best cups.
Now consider this.Life is the coffee. The jobs, money and in society are the cups. They are just to hold life. and the type of cup does not change the quality of our life. Sometimes, by only of the cup, we fail to enjoy the coffee that God has us. God offers us the coffee, not the cups. Please enjoy your coffee ! "
The happiest people don"t have the best of everything. They just make of everything.
Live simply. Love generously. Care deeply. Speak . And leave the rest to God.
