Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources (资源), we are short of(缺乏) others, for example, fresh water(淡水). It is reported that we will have no coal (煤) or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps (水龙头) when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, eve
A. eat too much
B. don’t work hard
C. waste things

Specialisation can be seen as a response to the problem of an increasing accumulation of scientific knowledge. By splitting up the subject matter into smaller units, one man could continue to handle the information and use it as the basis for further research. But specialisation was only one of a series of related developments in science affecting the process of communication. Another was the growing professionalisation of scientific activity.
No clear-cut distinction can be drawn between professionals and amateurs in science: exceptions can be found to any rule. Nevertheless, the word "amateur" does carry a connotation that the person concerned is not fully integrated into the scientific community and, in particular, may not fully share its values. The growth of specialisation in the nineteenth century, with its consequent requirement of a longer, more complex training, implied greater problems for amateur

[单项选择]Intelligence used to be seen as a fixed entity, some faculty of the mind that we all possess and which determines in some ways the extent of our achievements. Since the Intelligence Quotient was relatively unaffected by bad teaching or a dull home environment, it remained constant. Its value, therefore, was a predictor of children’s future learning. If they differed markedly in their ability to learn complex tasks, then it was clearly necessary to educate them differently—and the need for different types of school and even different ability groups within schools was obvious.
Today, we are beginning to think differently. In the last few years, re search has thrown doubt on the view that innate intelligence can ever be measured and on the very nature of intelligence itself. Perhaps most important, there is considerable evidence now which shows the great influence of the environment both on achievement and intelligence. Children with poor home backgrounds not only do less well in the
