问题 口语交际,情景问答题

阅读下面的材料,回答问题。(7分)

材料一:根据观测,20世纪70年代开始,太阳辐射量在不断增强,地球气温不断升高,蒸发加强,使我国黄河流域乃至华北、西北地区更加干旱。

材料二:森林覆盖率低,水土流失严重 历史上植被状况的恶化对黄河断流影响很大,在黄土高原,原有的茂密森林在唐代、宋代之后遭到人为的毁灭性破坏,直到今天,黄河流域的森林覆盖率仍然远低于全国平均水平,其生态破坏的趋势远未能得到根本性的遏制,甚至于有所发展

材料三:20世纪50年代以来,黄河流域人口猛增,人类生产与生活规模无节制扩大,耗水量呈现急剧上升态势。在枯水年份或者枯水季节,黄河沿岸各地只从自身利益考虑,纷纷引水、蓄水、争水、抢水,水资源管理混乱,水量分配不合理,水荒矛盾更加突出。加重了下游水资源匮乏的程度。

小题1:黄河是母亲河,给我们留下了灿烂的文明,请写出两句关于“黄河”的诗句。(2分)

小题2:据资料显示,90年代以来,黄河下游断流日趋严重,几乎年年断流,而且断流的时间越来越长,到1997年断流226天,一年中竟然有2/3的时间断流。从上面几则材料中,你发现黄河断流可能是因为哪些因素。(3分)

小题3:根据以上材料,请你为拯救黄河提两条合理的建议。(2分)

答案

小题1: 黄河之水天上来 奔流到海不复回 黄河远上白云间 一片孤城万仞山等(2分)

小题1:气温升高或气候变暖 生态环境恶化或植被覆盖率低 耗水量激增监管不力(3分)

小题1:植树造林 加强监管 有节制地用水等(2分)

积累黄河诗句合理,书写正确即可;总结原因,表述合理即可;建议只要合理即可。

单项选择题 案例分析题

Transportation Decision Transportation decision consists of the following parts: 1.Selection of the mode is determined by the consideration of distance,cargo weights,linkage,timing and other requirements.Generally speaking,rail has high fixed cost and the relatively low variable cost.It can move heavy,large quantity of cargo in the long distance.But,rail is disadvantaged because of the longer transit time and less frequent service than motor. Motor carriers such as truck companies offer door-to-door service,that is,the cargo can be shipped from the shipper'swarehouse to the consignee's.Trucking fixed cost is the lowest of any carrier,because the equipment is fairly cheap and the motor carriers do not have to invest in the roads on which they run their operations.However,their variable costs are very high.Its expenses include two major components:firstly,the pick-up and delivery costs;secondly,there are gas or fuel costs,labor expenses and toll roads fees to be paid to highway and toll road operators Therefore,motor transport is good for cargo with small quantity to be shipped within short distances. Water is the predominant choice of transportation as it has the capacity to take greatest quantity,travel longest distance with lowest cost.Transport by sea accounts for 80% of in-ternational trade.The major expenses for water are expenses associated with investment and maintenance of the ships and terminals.For example,a 100000-ton container ship costs US$ 200 million.Terminal associated costs include harbor fees and the cost for loading and unloading the goods. Transport by air has the highest cost but it is fast with the lowest ratio of loss and dam-age.If you need to deliver an urgent order,there is little choice but by air. 2.Transport service provider is selected for its experiences,equipment,services and prices.Competitive in the transport industry usually drives the prices down and motivates for better services.A company also chooses its transport service provider because of its long-standing business relationship with certain shipping companies. 3.The alternative routing and scheduling is specific for motor only because railway and water have strict route and timetable.Motor has special advantage in terms of flexibility.It has the ability to load goods at greater frequency,travel through different routes and making deliveries to different loca-tions.Questions:

How is the transportation mode selected?()

A.By suppliers.

B.By customers.

C.By consideration of distance,weight,linkage and other requirements.

D.By government requirements.
