【简答题】
When I entered Berkeley. I hoped to earn a scholarship. Having been a Straight-A student, I believed I could 36 tough subjects and really learn something. One such course was World Literature given by Professor Jayne. I was extremely interested in the ideas he 37 in class. When I took the first exam, I was 38 to find a 77, C-plus, on my test paper, 39 English was my best subject. I went to Professor Jayne, who listened to my arguments but remained 40 . I decided to try harder, although I didn’t know what that 41 because school had always been easy for me. I read the books more carefully, but got another 77. Again, I 42 with Professor Jayne. Again, he listened patiently but wouldn’t change his 43 . One more test before the final exam. One more 44 to improve my grade. So I redoubled my efforts and, for the first time, 45 the meaning of the word “thorough”. But my 46 did no good and everything 47 as before. The last hurdle(障碍)was the final. No matter what 48 I got, it wouldn’t cancel C-pluses. I might as well kiss the 49 goodbye. I stopped working hard. I felt I knew the course material as well as I ever would. The night before the final, I even 50 myself to a movie. The next day I decided for once I’d have 51 with a test. A week later, I was surprised to find I got an A. I hurried into Professor Jayne’s office. He 52 to be expecting me. “If I gave you the A-pluses you 53 , you wouldn’t continue to work as hard.” I stared at him, 54 that his analysis and strategy(策略) were correct. I had worked my head 55 , as I had never done before. I was speechless when my course grade arrived: A-plus. It was the only A-plus given. The next year I received my scholarship. I’ve always remembered Professor Jayne’s lesson: you alone must set your own standard of excellence. 小题1: A.take B.discuss C.cover D.get 小题2: A.sought B.presented C.exchanged D.obtained 小题3:.

【简答题】某石灰厂对60g生石灰样品(含杂质SiO 2 和CaCO 3 ,SiO 2 不溶于水,也不与酸反应)进行分析实验:①将试样放入质量为80g的大烧杯里,逐滴加入365g20%的盐酸,恰好完全反应;②反应后,待溶液冷却后,称得烧杯连同杯内物质共502.8g. 试计算: ①试样中碳酸钙和生石灰各多少克? ②反应后所得溶液中溶质的质量分数为多少?
【简答题】称取石灰石试样0.2303g,经酸溶后于合适的酸度下加入过量的(NH 4 ) 2 C 2 O 4 溶液,使Ca 2+ 沉淀为CaC 2 O 4 ,经过滤、洗涤后,将沉淀溶于稀H 2 SO 4 中使其生成H 2 C 2 O 4 ,再用 标准溶液滴定所得到的溶液,共消耗22.30cm 3 ,计算此石灰石中CaCO 3 的质量分数。
【简答题】计算题:将0.5000g石灰石试样溶于25ml0.5mol/l盐酸溶液中,用0.25mol/l的氢氧化钠溶液滴定过剩的盐酸溶液,消耗氢氧化钠溶液14ml,试求石灰石中碳酸钙的百分含量并写出反应方程式。(CaCO3的分子量是100)。
【简答题】称取石灰石试样0.2303g,经酸溶后于合适的酸度下加入过量的(NH 4 ) 2 C 2 O 4 溶液,使Ca 2+ 沉淀为CaC 2 O 4 ,经过滤、洗涤后,将沉淀溶于稀H 2 SO 4 中使其生成H 2 C 2 O 4 ,再用 标准溶液滴定所得到的溶液,共消耗22.30cm 3 ,计算此石灰石中CaCO 3 的质量分数。
【单选题】关于 IS 曲线,如下哪个说法是正确的?

IS曲线代表商品与货币市场均衡
D.
IS曲线代表总供给与总需求相等
【简答题】称取 0.5000g 石灰石试样,溶解后,将 Ca 2+ 沉淀为 CaC 2 O 4 ,经过滤、洗涤后将沉淀溶于稀 H 2 SO 4 中,用 c ( 1/5KMnO 4 ) =0.1010mol/L 的高锰酸钾标准滴定溶液滴定,到达终点时消耗 35mL 高锰酸钾溶液,计算试样中 Ca 的质量分数。
