Which one is not mentioned in above section.( )(A) increasing the profitalbility(B) improving the capacity(C) using large amount of catalyst(D) lowing the energy requirement(ii) This often means that there will be close liaison(联系) between the chemical companies’technical sales representatives(代表) and the customer, and the level of technical support for the customer can be a major factor in winning sales.2. We can conclude that ( ) from the above section.(A) there are close liaison between the products and customer.(B) a major factor for winning sales is the level of technical support for customer(C) a major factor in winning sales is the close liaison between the chemical companies’technical sales representatives and the customer.(D) the major factors in winning sales are the the close liaison between the chemical companies’technical sales representatives and the customer and the level of technical support for the customer.(iii) A major advance in polymer chemistry was provided by the work of Karl Ziegler and Giulio Natta, which led in 1955 to the introduction of some revolutionary (革命性的) catalysts which bear their name. During the late 1970s production of linear (线性) low-density polyethylene (聚乙烯) was commercialized.3. The introduction of some revolutionary catalysts is due to the in polymerchemistry.4. This paragraph implies that（）(A) During the late 1970s, the linear low-density polythylene are widely produced.(B) In 1955, the linear polyethylene was commercialized.(C) Some revolutionary catalysts were introduced during the late 1970s..(D) The linear low-density polyethylene bears the name of Karl Ziegler and Giulio Natta. (iv) The basic components (构成) of a typical chemical process are shown in Fig. 1, in which each一、阅读与理解（每小题2分，共20分）二、翻译一——英译汉（每小题6分，共30分）三、翻译二——汉译英（每小题6分，共30分）四、翻译三——摘要（20 分）block (方框) represents (代表) a stage in the overall (全部) process for producing a product from the raw materials. Fig. 1 represents a generalized (一般的) process; not all stages will be needed for any particular process and the complexity (复杂程度) of each stage will depend on the nature of the process.5. This paragraph implies that ( )(A）Figure 1 represents particular process.(B）each block in Fig.1 represents a stage of particular process.(C）the complexity of each stage will depend on the cost.(D）not all stages in Fig.1 are included in every chemical process.6. Fig 1 represents a process for producing a product from the. (v) There are over three million known compounds, with no end(没有尽头) in sight as to the number that can and will be prepared(制备,准备) in the future. Each compound is unique(唯一的) and has characteristic(特有的) physical and chemical properties(性质).Let us consider in some detail two compounds—water and mercuric(汞,水银) oxide.Water is a colorless, odorless(无嗅), tasteless (无味) liquid that can be changed to a solid, ice at 0℃and to a gas, steam(蒸汽) at 100℃. It is composed of two atoms of hydrogen(氢) and one atom of oxygen per molecule (分子), which represents(表现) 11.2 percent hydrogen and88.8 percent oxygen by mass (质量). Water reacts chemically with sodium (钠) to producehydrogen gas and sodium hydroxide(氢氧化物), with lime (石灰) to produce calcium (钙) hydroxide, and with sulfur(硫) trioxide(三氧化物) to produce sulfuric(硫的,硫磺的) acid(酸).No other compound has all these exact(精确的) physical and chemical properties; they are characteristic of water alone.Mercuric oxide is a dense(致密的), orange-red powder composed of a ratio of one atom of mercury to one atom of oxygen. Its composition(组成) by mass is 92.6 precent mercury and7.4 percent oxygen. When it is heated to temperatures greater than 360℃, a colorless gas,oxygen, and a silvery(银子似的；有银色光泽的) liquid metal, mercury, are produced. Here again are specific(明确的,特定的) physical and chemical properties belonging to mercuric oxide and to no other substance. Thus, a compound may be identified(区别,识别,鉴定) and distinguished(区分) from all other compounds by its characteristic properties.7. Which one is not correct as to the above passage. ( )(A）There are more than 3 million compounds which are known at present.(B）The number of compounds which can be prepared in the future could be calculated.(C）Every compound is special and unique.(D）There are characteristic physical and chemical properties for each compound.8. There are two compounds are detailed introduced in this passage, they areand , respectively.9. This passage suggested that ( )(A) Water is liquid, but can be changed into solid and gas under cetain conditions.(B) Water is composed of one atom of hydrogen and one atom of oxygen per molecule.(C) Water could react with sodium or lime, but could not react with sulfur trioxide.(D) No other compound has exact physical and chemical properties expect water and mercuricoxide.10. Mercuric oxide has the following properties expect ( )(A）dense (B）orange-red color(C）turn to liquid at more than 360o C(D）the liquid mercury are much darker in color than mercuric oxideII.翻译一（Translating English to Chinese，英译汉)1. Next reaction (反应) was designed based on the obtained experimental (实验的) data.2. The explosive growth in petrochemistry (石油化学) was largely due to the enormous increaseof synthetic polymers (合成聚合物).3. Because of the diversity (多样性) of operations (操作) and close links (联系) in many areas, there is no simple definition (定义) of the chemical industry.4. The purpose of this meeting is to provide information and knowledge in order to reduce uncertainty (不确定性), solve problems and provide better data.5. The basic components (构成) of a typical chemical process are shown in Fig. 1, in which each block (方框) represents (代表) a stage in the overall (全部) process for producing a product from the raw materials.III.翻译二（Translating Chinese to English，汉译英)1. 值得注意的是这些化合物(compounds)的大多数都是无机物(inorganic materials)。
