【文章內容簡介】 gs a beautiful picture. 3． (1)T (2)F I have reached the point where I am supposed to make a decision of my own. Ⅳ .語篇助記 I used to hate science, because it was difficult and plicated for me. Although through physics, I know the followings: water has three states, which are solid, liquid and gas。 when water boils, it gives off steam。 when heated, metals, such as iron used in electrical equipment, potassium, sodium, calcium and copper and so on, expand rather than contract。 steel is a mixture of iron with other substances. I still have no much interest in science. But half a year ago, a lecture made by Professor Lee, who had made many discoveries in his areas of science, astonished and changed me. We were proud of him for his winning the Nobel Prize for Chemistry. The aim of the lecture was to develop the interest of teenagers in science. Professor Lee, director of Chemistry Department of a university, brought many science facilities with him, including balance, tongs, tubes, crucible etc. He did several experiments, and one of them interested me. We drew a conclusion with his help that iron doesn39。t rust in dry air and in air－ free water but rust in ordinary water because iron reacts with oxygen in the water. Professor Lee also told us copper makes partial reaction when heated in oxygen, while it makes no reaction when it is placed in water. What a wonderful world! At the end of the lecture, Professor Lee said teenagers were supposed to care more about the latest discoveries in science. Now I have known how snow forms and how salt dissolves in water. 譯文： 我過去不喜歡科學 ， 因為它對我來說很難 ， 而且很復雜 。盡管通過物理 ， 我知道了下列一些事情：水有三態(tài) ， 即固體 、液體和氣體；當水沸騰時 ， 它會釋放出蒸汽；當金屬 ， 如用于電氣設備中的鐵 、 鉀 、 鈉 、 鈣和銅等被加熱時 ， 它們會膨脹而不是收縮；鋼是鐵與其他物質的混合物 。 但我依舊對科學沒什么興趣 。 但半年以前 ， 李教授作的一次演講使我驚愕而且改變了我 。 這位李教授在他個人的 (研究 )領域里有很多
