T: In which ways are the fields of science important to our everyday life? SK: Geograph is important. If we do well in it, we can find more coal, gas and oil, as well as all kinds of metal. SL: Meteorology is important. If we master it, we can tell our farmers much information about farming. If so, they will increase their productivity and avoid losses. SM: In our geograph lessons, our teacher told us that the stars and planets in the universe have effects on the earth, especially the weather on the earth. So we should learn astronomy well and know as much about it as possible so that we can forecast their effect. SN: Biology is an important subject. It affects our everyday life directly. If we develop better medicine, some diseases will be got rid of. SARS,for example, broke out in our country last year. We needed a lot of effective medicine then. If it had not been for the success our scientists achieved, we would have had much more losses. T: OK. Let's stop here. Knowledge is power.
