[简答题]某市博览中心的机电工程由某安装公司总承包，合同约定安装公司负责设备釆购、施工和试运行验收，工期为2个月，合同价为固定总价。机电工程中的一些主要设备由业主指定供货商，其中空调工程的冷水机组等设备，业主指定了某国厂商的产品。安装公司及时向厂商进行了产品询价，得知设备从订货、运输到施工现场最少需要6个月。安装公司依据冷水机组的型 号、规格、数量、技术标准、到货地点、质量保证、运输手段、结算方式和产品价格与厂商签订了设备供货合同。
工程施工到6个月后，因该国的政局不稳定，冷水机组等设备延期60d到达我国口岸，所以 冷水机组等设备在通关时，未经商检就直接运到施工现场。安装公司组织本公司人员对设备进行了开箱验收。因设备晚到60d，安装公司调整了施工进度计划，增加施工人员和机械设备，加班加点，冷水机组等设备按原计划安装到位，通电试运行并验收合格。由于安装公司因赶工期增加了费用支出，向业主提出费用索赔，被业主拒绝。

Genetically Modified Food
Ever since they were first put on the market in the early 1990s,genetically modified(GM，转基因）foods have been increasingly developed and marketed in many countries in the world, mainly on the basis of their promise to end the worldwide food crisis.______(46)Even if it would,is it the best solution?
Despite what it promises,GM technology actually has not increased the production potential （潜力）of any crop.______(47)For instance,a report that analyses nearly two decades of research on major GM food shows that GM engineering has failed to significantly increase US crop production.
______(48)While GM seeds are expensive,GM companies tell farmers that they will make good profits by saving money on pesticides（杀虫剂）.On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops."The promise was that you could use less chemicals and boost production.But neither is true,"said Bill Christison,President of the US National Family Farm Coalition.
At the same time,the authors of the book World Hunger:Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production. ______(49)These indeed deserve our efforts and money. Meanwhile,the rise in food prices results from the increased use of crops for fuel rather than food shortage,according to a 2008 World Bank report.
______(50)Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger,because better ways out are available,among which "green"farming is supposed to be the first choice.
_______（50）
A.Problems come from food distribution and politics.
B.But can GM technology solve world hunger problems?
C.In fact,studies show that the most widely grown GM crop has suffered reduced productivity.
D.As a matter of fact,scientists see better ways to feed the world.
E.Something else,however,has been on the rise.
F.GM has many benefits when it was used at the beginning.
