短文理解1
The Gobi Desert, in the north of China, is now seven times bigger than Britain. China has large desert areas and much of its agricultural land is being threatened by desertification, which is getting worse. In addition, soil erosion has led to a huge loss of farmland and the drying up of rivers. Consequently, the livelihoods of 35 million people are being threatened. Furthermore it is even affecting cities. The nearest sand dune is less than 100 miles from Beijing, where unpleasant sandstorms are becoming more frequent. The worse the situation, the more pressure there is on the government to take action.
The reasons for the changes are complex. It is clear that pollution of the air and water by factories is affecting the environment. Trees and other vegetation die, and so soil is eroded. The more trees that die, the less water is held in the earth. The need for wood for fuel and buildings leads to further deforestation, which causes further soil erosion. Local farmers find it more and more difficult to make a living. They end up using inefficient farming methods, which again leads to soil erosion.
The Government is carrying out anti-desertification projects, including the creation of a forest belt around deserts. The tree-planting campaign, known as the Great Green Wall, is meant to protect Beijing from sandstorms. China hopes to control the expansion o£ desert land by the year 2010 and plans to establish a protected eco-system in desert areas by 2050.
Questions 41一45.
41.Britain is   .
A.one eighth of the size of the Gobi Desert
B.20% of the size of China
C.as big as the Gobi desert
D.bigger than Gobi desert
42.The total desert area of China is .
A. decreasing B. remaining constant
C. not mentioned in the text D. increasing
43. The trees die because.
A. the soil is poor B. the air and water is polluted
C. they get diseases D. they are not well planted by people
1226
44.The Chinese government is planting trees around .
A.the deserts
B.China
C.Beijing
D.the north of China
45.The expansion of desert land .
A.will definitely be controlled by 2010
B.won’t be controlled by 2010
C.should be controlled by 2010
D.must be controlled by 2010
短文理解2
Recently, a rather sophisticated(老练的)woman told me shyly that she saves up all her presents until Christmas morning and then sits up in bed and opens them, just like a child. She thought I would laugh at her and say how silly she was. But in fact I was absolutely delighted to meet someone who treats Christmas as 1 do.
Many people today have a very different attitude to Christmas. They think it’s just a time when shopkeepers make a lot of money and everyone rushes round buying presents they don’t want to give and food they don’t want to eat. But have they grown so far away from their own childhood that they can’t remember all the good things.
First of all, Christmas takes you out of the ordinary dull routine of life. For children, the fun begins weeks before when the decorations are put up, and excitement gradually increased as December the 25山 approaches.
Everyone seems much friendlier to each other than usual at Christmas time.
You can lean(倚靠)on a car window when you? re stopped at the traffic lights and say uMerry Christmas,v and people will smile and respond. You probably wouldn’t think of doing that at any other time of year. Perhaps it’s because most people are on holiday or because everyone knows that they are sharing a similar experience. Giving presents can be very satisfying, too, if you plan far enough in advance and really think of the right present for the right person.
Indeed, whatever shopkeepers gain out of Christmas, it is still a “holy day,” the words from which “holiday” is derived, and it gives people time to pause and concentrate for a moment on non-commercial values.
Questions 46 —50.
46.When the woman told the writer her Christmas story> she was shy because
A, she thought it was too private B. it showed her greediness
C. she thought it was too childish D. it showed her honesty
47.Many people have different attitude to Christmas because .
A.shops earn too much money
B.people eat too much food
C.everyone gives out a lot of gifts
D.the festival is too commercialized
48.The writer thinks that Christmas .
A.brings excitement into the boring life
B.begins several weeks before Dec. 25th
C.gives a better time to children than adults
D.is a time for the shops to make money
49.People are more friendly to each other at Christmas time because .
A.they receive a lot of gifts and good wishes from other people
B.Christmas provides them with an experience they can share
C.more people put on a smiling face and reply to greetings
D.shopkeepers are happy when they can make more money
50.The main idea of the passage is that .
A.adults do not enjoy Christmas as much as children do
B.early planning is the key to a good time for Christmas
C.shopping for presents is a part of the Christmas celebration
D.Christmas has not lost its charm in modern society

短文理解3
The Internet’s ability to connect a wide range of cultures encourages variety. However» for the time being, English dominates online because from the start it was the lingua franca of cyberspace. Will this always be the case?
Currently about 70% of Internet content is in English, but only about 44% of Internet users are native English speakers. Worldwide, native Spanish speakers outnumber native 1228
speakers of English online, and the number of native Chinese speakers is greater than both those groups put together. Statistics show that the situation is changing. For instance, three years ago 75% of web pages were in English, but that number has dropped to 50% today.
Furthermore? Internet use among non-native speakers of English is growing at a faster rate than that of native English speakers. By 2003, the number of native English-speaking web users will have dropped to 29%, according to one estimate.
As a result, some researchers say that the early predominance of English is going to decline. They say that English will keep a special role in connecting communities whose native languages are different, but in about 20 years, time, Spanish, French, Arabic and Chinese will also have taken on this connecting role. If this is true, then monolingual native English speakers may be more likely to learn another language and also become bilingual» or even multilingual.
Questions 51—55.
51.English became the dominant Internet language because it is spoken in cyberspace.
52.Less than half of Internet users have English as their first language.
53.There are fewer native Spanish speakers than native English speakers online.
54.Approximately 40% of Spanish speakers have some sort of access to the Internet.
55.Only about half of web pages are in English compared to three-quarters three years ago.

  • 游客 购买了资源 某施工单位(乙方)与某建设单位(甲方)签订了某项工业建筑的地基处理与基础工程施工合同。由于工程量无法准确确定,根据施工合同专用条款的规定,按施工图预算方式计价,乙方必须严格按照施工图及施工合同规定的内容及技术要求施工。乙方的分项工程首先向监理工程师申请质量认证,取得质量认证后,向造价工程师提出计量申请和支付工程款。 工程开工前,乙方提交了施工组织设计并得到批准。 问题: 1. 在工程施工过程中,当进行到施工图所规定的处理范围边缘时,乙方在取得在场的监理工程师认可的情况下,为了使夯击质量得到保证,将夯击范围适当扩大。施工完成后,乙方将扩大范围内的施工工程量向造价工程师提出计量付款的要求,但遭到拒绝。试问造价工程师拒绝承包商的要求合理否?为什么? 2. 在工程施工过程中,乙方根据监理工程师指示就部分工程进行了变更施工。试问工程变更部分合同价款应根据什么原则确定? 3.在开挖土方过程中,有两项重大事件使工期发生较大的拖延:一是土方开挖时遇到了一些工程地质勘探没有探明的孤石,排除孤石拖延了一定的时间;二是施工过程中遇到数天季节性大雨后又转为特大暴雨引起山洪暴发,造成现场临时道路、管网和施工用房等设施以及已施工的部分基础被冲坏,施工设备损坏,运进现场的部分材料被冲走,乙方数名施工人员受伤,雨后乙方用了很多工时清理现场和恢复施工条件。为此乙方按照索赔程序提出了延长工期和费用补偿要求。试问造价工程师应如何审理?

  • 游客 购买了资源 由某企业承建的某多功能现代化商务综合大厦,地上46层,地下3层,全现浇钢筋混凝土框架-剪力墙结构,主体结构采用泵送混凝土等新技术。建筑物周边都十分接近规划红线,周边建筑及地下管线对因工程基坑开挖引起地层变形移动影响十分敏感,且基坑北面临近地铁。该工程地下室基坑开挖深度较大,为确保基坑开挖安全编制了专项施工方案,并由安全总监签字确认后实施。该地下室位于总厚达40m多的淤泥质土之中,根据本工程的特点,经多方案比较,决定基坑围护结构采用80cm厚的地下连续墙,而支护结构则为五道钢筋混凝土水平支撑的总体方案。经验算,可以满足结构变形和稳定要求,确保地下室开挖施工不致于影响地铁的正常运行、周边道路、建筑物及各种地下管线的正常使用。在工程施工中发生如下事件: 事件一:本工程地下水位较高,约为-0.5m,开挖范围位于淤泥质土体内,含水量大,施工必须事前采取降水措施,因基坑围护是采用地下连续墙,具有较好的挡水和抗渗性能。结合实际情况,决定采用轻型井点降水并编制了降水施工方案。 事件二:根据地质勘察资料、上部结构形式、荷载和施工条件等情况,基础施工采用人工挖孔扩底灌注桩与平板式筏形基础,板厚2m,桩基承台连同地下室的筏形基础同时展开施工。基础底板厚2m,桩基承台厚1.8m,混凝土强度等级C40,抗渗等级P8。由于承台和筏板混凝土浇筑量大,在开始阶段施工中出现了少许裂缝。为确保施工质量,项目部制定了以下控制裂缝的措施: (1)优先选用低水化热的普通硅酸盐水泥拌制混凝土,并适当加入木质素磺酸钙减水剂。 (2)在保证混凝土设计强度等级的前提下,适当提高水灰比,减少水泥用量。 (3)降低混凝土的浇筑温度,控制混凝土内外温差在30℃以内。 (4)分层分块逐步浇筑,加强养护,及时对混凝土进行覆盖保温、保湿材料。 (5)预埋冷却管,通入循环水将混凝土内部降温。 事件三:在进行办公楼大厅顶盖模板支架预应力混凝土空心板现场浇筑施工时,发生模板支撑体系坍塌事故,造成6人死亡、12人受伤。经有关部门调查,造成事故主要原因是模板支架搭设质量不符合要求;现场搭设模板支架中使用的部分钢管材料存在质量缺陷;施工现场管理存在严重问题。事后,建设行政主管部门对该施工企业作了相应的行政处罚,公安机关依法对有关责任单位的涉案人员追究刑事责任。 问题 (1)结合事件一说明井点降水施工方案的内容主要包括哪些? (2)请指出本案例中有哪些不妥之处,并说明理由。 (3)分析说明事件二承台和筏板混凝土浇筑中出现裂缝的主要原因是什么? (4)事件三工程事故可定为几级重大事故?请说明理由。 (5)事件三事故类型是什么?
