第1题（12分）通常，硅不与水反应，然而，弱碱性水溶液能使一定量的硅溶解，生成Si(OH)4。

1-1已知反应分两步进行，试用化学方程式表示上述溶解过程。

早在上世纪50年代就发现了CH5+的存在，人们曾提出该离子结构的多种假设，然而，直至1999年，才在低温下获得该离子的振动-转动光谱，并由此提出该离子的如下结构模型：氢原子围绕着碳原子快速转动；所有C-H键的键长相等。

1-2该离子的结构能否用经典的共价键理论说明？简述理由。

1-3该离子是（）。

A.质子酸B.路易斯酸C.自由基D.亲核试剂2003年5月报道，在石油中发现了一种新的烷烃分子，因其结构类似于金刚石，被称为“分子钻石”，若能合成，有可能用做合成纳米材料的理想模板。

该分子的结构简图如下：1-4该分子的分子式为；1-5该分子有无对称中心？1-6该分子有几种不同级的碳原子？1-7该分子有无手性碳原子？1-8该分子有无手性？第2题（5分）羟胺和用同位素标记氮原子（N﹡）的亚硝酸在不同介质中发生反应，方程式如下：NH2OH+HN﹡O2→ A+H2ONH2OH+HN﹡O2→ B+H2OA、B脱水都能形成N2O，由A得到N﹡NO和NN﹡O，而由B只得到NN﹡O。

2007年广东省联赛答案解释1、C；渗透压只跟血浆中的分子、离子浓度有关，与蛋白质的分子质量无关。

（1）概念：渗透压指的是溶质分子通过半透膜的一种吸水力量，其大小取决于溶质颗粒数目的多少，而与溶质的分子量、半径等特性无关。

由于血浆中晶体溶质数目远远大于胶体数目，所以血浆渗透压主要由晶体渗透压构成。

血浆胶体渗透压主要由蛋白质分子构成，其中，血浆白蛋白分子量较小，数目较多（白蛋白>球蛋白>纤维蛋白原），决定血浆胶体渗透压的大小。

（2）渗透压的作用晶体渗透压——维持细胞内外水平衡胶体渗透压——维持血管内外水平衡2、B；A：红细胞本身没有线粒体，不能进行有氧呼吸；B：无氧呼吸停止后，Na-K泵停止工作，K+外流导致血浆中的浓度升高；C：跟外排作用无关；D：物质代谢减慢才对。

3、C；A：最多通气为零，不可能为负值；B：8.5KPa以后基本趋于平衡；D：反射弧的效应器不应该是肺泡，而是呼吸肌。

4、C；AD：都是内环境里的缓冲物质，可以跟酸中和；B：因为蛋白质是弱酸性的，所以和钠构成强碱弱酸盐，也有缓冲特性，可以与酸反应；C：这反应应该也可以发生，但题目说的是内环境中，而血红蛋白只在红细胞内，所以不属于内环境。

5、C；昆虫除原尾目无触角、高等双翅目和膜翅目幼虫的触角退化外，其它种类都有1对触角。

触角长在昆虫两只复眼的中上方，昆虫活动的时候，这两根触角总是不停地摆动着，东察西探，象是寻找猎物的雷达。

触角是主要的感觉器官，有嗅觉、触觉和听觉的功能。

触角能够帮助昆虫寻找食物和配偶，并探明身体前方有无障碍物。

在有些昆虫中，触角还有其它用处，例如雄性芫菁在交配时用来握住雌虫，魔蚊幼虫用来捕捉食物，仰泳蝽的触角在水中能平衡身体，水龟虫则用来帮助呼吸。

触角都长在头前面的两个叫做触角窝的小坑里。

触角通常有许多小节组成，基本上可以分为三大节。

靠近触角窝的一节通常比较短粗，是支撑上面各节的，相当于树叶的柄，叫做柄节。

Part III Reading comprehension (40 minutes) Task 1Self-employed private physicians who charge a fee for each patient visit are the foundation of medical practice in the United States. Most physicians have a contract relationship with one or more hospitals in the community. They send their patients to these hospitals, which usually charge patients that they care for. Some hospitals belong to a city, a state or, in the case of veterans’ hospitals, a federal government agency. Others are operated by religious orders(教堂) or other non-profit groups.Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government’s Public Health Service.Physicians are among the best paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to earn incomes of more than $100 000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would be physicians first attend college for four years, which can attend medical school for four years. Tuition alone can exceed $10 000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency（实习期）in a hospital, the first year as an apprentice physician. The hours are long and their pay is relatively low.Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also of each other’s patients in emergencies.Physicians word long hours and must accept a great deal of responsibility. Many medicalprocedures, even quite routine ones, involve risk. It is understandable that physicians want to be well rewarded for making decisions which can mean the difference between life and death.36.According to the passage, it is very unlikely that an American hospital is owned by_____.A. a churchB. a corporation.C. a cityD. a state37.The expenses for becoming a doctor are spent on _______.A. schooling and training C. facilities he or she usesB. practice in a hospital D. education he or she provides38.According to the passage, how long does it take for a would-be physician to become anindependent physician in the USA?A. About seven yearsB. Eight yearsC. The yearsD. About twelve years39.Sometimes several physicians set up a group medical practice mainly because .A.they may have more patientsB.they can take turns to work ling hoursC.facilities may be a big burden to an individualD.no one wants to assume too much responsibility40.Which of the following statements could fully express the author’s view towardsphysicians’ payment in the USA?A.Physicians’ expensive education and the characteristics of their work make them welldeserve the handsome pay.B.It is reasonable for physicians to have a large income because their work is verydangerous.C.Physicians should be better paid because they work long hours under bad conditions.D.Physicians shoulder great responsibilities, so it is understandable that they should bewell rewarded.Task 2Don’t Waste Advertising DollarsWalking down any of Shanghai’s main shopping streets this week, newcomers might think the locals have been celebrating Christmas for centuries. Christmas may not be a customary holiday in China, but businessmen in Shanghai know it will bring something more valuable than tradition: people willing to spend money. Most Chinese may feel little connection with the Christmas celebration, but with most shops offering discounts(折扣), the message couldn’t be clearer—it is the season to part with one’s hard-earned cash.Much of that marketing drive is directed towards the thousand of foreigners and forting companies seems no avoiding the season’s commercial(商业的) greetings. Along some major roads, nearly every shop window displays some symbols to the holiday: a man-made fir tree(杉树) with lights, or a snowman.With an increasing number of Westerners arriving in the city for work, young Shanghainese, eager to keep pace with fashions, have begun to show their interest in Christmas. But some people still don’t think Christmas is an important festival in China. At least it is important than the New Year and China’s Spring Festival.41. In the first sentence, the word ―newcomers‖ (Line 1, Para. 1) probably means.A. people who are very youngB. people from other countriesC. local peoplesD. Shanghainese42. To the business people in Shanghai, Christmas will bring ________.A. profitsB. greetingsC. discountsD. tradition43. Which of the following statements is true?A.Christmas is the season for common people to earn money.B.Most Chinese people think they have something to do with Christmas.C.Christmas is the season people will hold their hard-earned money tightly.D. Few Chinese people feel they are connected with the Christmas celebration.44. Why do some young Shanghainese show great interest in Christmas?A. They want to follow the up-to-date Western fashions.B. They think Christmas is more important than New Year’ Day.C.They think themselves connected with Christmas celebration.D.They want to part with their hard-earned cash during Christmas.45. What is the author’s idea towards Christmas celebration?A.Chinese young people should not celebrate Christmas seasons.B.Young people should show their interest in not Christmas celebrations.C.Christmas is a good season for business people to earn money in China.D.Different people have different views towards the western style celebration.Task 3Arora HillsA secure place, a peaceful place, a better placeCome and live next to Nature. In the community of Arora Hills you are surrounded by the beauty of life. This exciting new community is home to three winding streams, expansive recreational parks and miles of nature trails as well as peaceful rolling hills.
