在现代文阅读试题中,能力层次要求较高的题.多以“概括表述”的形式出现.练好这类题,不仅能带动现代文阅读其它题的准确迅速解答,而且还能有效地提高理解分析和语言表达能力.下而例谈这类题的解答技巧.[文段]①C_(60)结构稳定.性质活泼奇特.用途广泛.②它的分子内有许多的π键.是加成反应的活性源.在一定条件下与较多的试剂发生加成反应,C_(60)H_(18)、C_(60)H_(37)、C_(60)F_8、C_(60)F_(42)、C_(60)F_(60)等都是它的加成物.③其中高氟化物,是高温润滑剂、耐热和防水的理想材料.④C_(60)的另一种反应是在球的六边形边上多处形成桥键.⑤C_(60)的第三种反应简称为移植反应.⑥因为巴基球外刚内空,化学大师们从六边形的通道,经过反应将其它原子或原子团“填”入巴基球的“笼”中,产生具有特殊导电性和催化功能的新物质,开辟了十分喜人的全新的化学领域.
In the modern reading examination questions, the questions with higher competence levels are often presented in the form of “general expressions.” Such questions can not only lead to accurate and prompt answers to other questions in modern reading, but also can effectively improve. Understand the analytical and linguistic expression skills. Next, talk about the skills of answering such questions. [Text] 1C_(60) Stable structure, lively and peculiar in nature, versatile. 2 It has many π bonds in its molecule. The active source of the reaction. Addition reaction with more reagents under certain conditions, C_(60)H_(18), C_(60)H_(37), C_(60)F_8, C_(60)F_(42 ), C_ (60) F_ (60), etc. are all its adducts. 3 Among them is high fluoride, which is the ideal material for high temperature lubricant, heat resistance and waterproof. Another reaction of 4C_ (60) is in the ball. On the side of the hexagon, several bridges are formed. The third reaction of 5C_(60) is referred to simply as the transplant reaction.6 Because the base of Bakyo is just outside the space, the masters of chemistry pass from the hexagonal channel and pass through the reaction. Atomic or atomic groups “filled” into the “cage” of the Baky ball, creating new substances with special conductivity and catalytic functions, opening up a very exciting new field of chemistry.
