My colleagues in this famous photograph 2 to see “Bucky get the Prize”. This picture was taken on September 11, 1985, the day before we sent off the manuscript describing the discovery of C60 to the editorial offices of Nature(and 3 itself).Every one of the people in that photograph 4 (with the exception of the one woman walking in the back- 5 who that mystery woman was) , 6 that there is also some sadness in our hearts today. While the chemistry prize this year is for the discovery of the fullerenes, it is given to individuals, and this individual honor can be shared by no more than three. The Nobel committee has done 7 with this problem. We understand. But the sadness remains. On the other hand, 8 the limit of three. For example, 9 when there is only one person receiving an award in physics or chemistry. It was told that you just get one lecture for that prize. Now that 10 of having a long lecture from each of the three winners this year in each of the two fields, physics and chemistry, all on the same day and in the same room. I can see that one must set limits somewhere. This discovery was one of the most spiritual experiences that 11. 12 that this spiritual experience, this discovery of what Nature has in store for us with carbon, is still ongoing. 13 “The Discovery of the Fullerenes” but rather “Discovering the Fullerenes“. Fullerene researchers worldwide 14 . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 III. Translate the following paragraphs into Chinese:1) The solubility rules mentioned above are rough approximations. Soluble can be taken to mean that several tens of grams of the compound will dissolve in 100 g of water at room temperature. Moderately soluble might mean from 5 to about 15 g of compound in 100 g of water. Only a gram or so of a slightly soluble compound and much less still of a very slightly soluble compound will dissolve in 100 g of water at room temperature.上面所讲的溶解度规则就仅仅是粗略的估计。易溶可以理解为室温下 100g 水中能溶解 该化合物几十克;中等溶解度是指在 100g 水中溶解 5-15g;室温下 100g 水中仅仅溶解 一克左右的是微溶,低于一克的是难溶化合物。 上面所讲的溶解度规则是粗略的估计上面所讲的溶解度规则是粗略的估计. 易溶(易溶(Soluble )可以理解为室温下在)可以理解为室温下在 100 克水中能克水中能 溶解该化合物几十克;中等溶解(溶解该化合物几十克;中等溶解(Moderately soluble)是指在)是指在 100 克水中能溶解该化合物克水中能溶解该化合物 5 至至 15 克;于室温下在克;于室温下在 100 克水中仅仅溶解克水中仅仅溶解 1 克左右叫微溶(克左右叫微溶( slightly soluble ) ,低于,低于 1 克克 为难溶(为难溶(very slightly soluble)化合物)化合物) 32) Which bonds or broken and the order in which they are formed or broken are described by a reaction mechanism. A mechanism consists of a sequence of chemical equations, one for each molecular collision. If the rates of individual steps in a mechanism can be predicted or measured, the overall rate of process can be calculated from them. The mechanism tells us which molecules need to collide and in what order. However, it does not provide much detail about the rate at which each step can occur, about how or why specific bonds are made and broken, or about how temperature affects the reaction rate.3) What should we teach to help students become scientifically literate? Most practicing scientists would argue that “science” connotes a process or procedure for making inquires about our world and for evaluating the hypotheses these inquires generate. The results of science give us a human perception of the
