甲公司与乙公司签订一购销合同,约定甲公司向乙公司提供空调机1000台,6月5日前交货,由乙公司自行提货。乙公司提货后三个月内付清全部货款230万元。乙公司以其所有的价值50万元的房产作为抵押。5月25日,乙公司与丙公司签订合同,将甲乙合同项下的空调机转售给丙公司,并告知丙公司直接向甲公司提货。4月5日,丙公司向甲公司要求提货时,甲公司因为未接到乙公司的通知,拒绝交付货物。丙公司与乙公司经过交涉后,乙公司通知甲公司向丙公司交货。丙公司于6月30日从甲公司提取了该批空调机。7月1日,甲公司将其向乙公司收取货款的权利让与丁公司,同时通知乙公司向丁公司付款,并保证:"如果乙公司不能支付货款,由甲公司承担责任"。同年9月,丁公司要求乙公司付款,乙公司告知丁公司货物由丙公司提走,应向丙公司要求付款。丁公司向丙公司要求付款,丙公司提出两项抗辩事由:(1)甲公司延迟交货,已错过最佳销售季节,导致空调机滞销;(2)所交空调机只能制冷不能制热,与乙丙合同所规定的质量不合,因此拒绝付款。根据《中华人民共和国合同法》、《担保法》的有关规定。 如乙公司拒绝支付货款,丁公司可以采取的措施有_________。
A. 要求甲公司支付230万货款
B. 行使对乙公司房产的抵押权
C. 行使对乙公司房产的抵押权不能获得清偿的部分,有权直接要求甲公司承担保证责任
D. 行使对乙公司房产的抵押权不能获得清偿的部分,应当对乙公司提起诉讼

One of the most vivid symbols of global warming is the torrents of melt water that drain from the lakes that form each summer on Greenland’s ice sheet. Recent studies have shown that this water, which flows deep into the ice through natural drainpipes called moulins, allows the ice to slide faster over bedrock toward the ocean. And the faster the ice flows, the faster sea levels rise. But a Dutch study using 17 years of satellite measurements in western Greenland suggests that the movement associated with the meltwater is not as rapid as had been feared. The acceleration appears to be a transient summer phenomenon, the researchers said, with the yearly movement actually dropping slightly in some places. "The positive-feedback ,mechanism between melt rate and ice velocity," says the report, published Friday in the journal Science, "appears to be a seasonal process that may have only a limited effect on the response of the ice sheet to climate warming over the next decades." Greenland is still losing more ice through melting than it gains through snowfall, other measurements show. The study was led by Roderik S. W. van de Wal of the Institute for Marine and Atmospheric Research of the University of Utrecht. He said the overall slowdown might be because of changing plumbing deep inside the ice. The study builds on earlier work also showing a limited overall change in ice flow from the surface melting. The authors and independent experts familiar with the research stressed that the findings did not preclude the possibility that more widespread surface melting could eventually destabilize big areas of Greenland, the world’s second largest ice storehouse. Richard B. Alley, a glaciologist at Pennsylvania State University, said that big lakes were likely to form as areas of melting spread inland, and that this could unlock new ice regions to start sliding more. But Dr. Alley and other experts said the new study showed that it was unlikely that Greenland’s ice had already become destabilized in ways that could cause a surge in sea levels. The third paragraph can be best understood that ______.
A. the ice sheet responds to climate warming in a certain season
B. melt rate and ice velocity are mutually influencing
C. climate warming exerts only seasonal influence on ice movement
D. ice movement associated with seasonal melting is exaggerated

案例: 某投资公司建造一幢办公楼,采用公开招标方式选择施工单位。招标文件要求:提交投标文件和投标保证金的截止时间为2003年5月30日。该投资公司2003年3月6日发出招标公告,共有5家建筑施工单位参加了投标。第5家施工单位于2003年6月2日提交了投标保证金。 开标会于2003年6月3日由该省建委主持。第4家施工单位在开标前向投资公司要求撤回投标文件和退还投标保证金。经过综合评选,最终确定第2家施工单位中标。投资公司(甲方)与中标施工单位(乙方)双方按规定签订了施工承包合同,合同约定开工日期为2003年8月16日。工程开工后发生了如下几项事件: 事件一:因拆迁工作拖延,甲方于2003年8月18日才向乙方提供施工场地,导致乙方A、 B两项工作延误了2天,并分别造成人工窝工6个和8个工日;但乙方C项工作未受影响。 事故二:乙方与机械设备租赁商约定,D项工作施工用的某机械应于2003年8月28日进场,但因出租方原因推迟到当月29日才进场,造成D项工作延误1天和人工窝工7个工日。 事故三:因甲方设计变更,乙方在E项工作施工时,导致人工增加14个工日,其他费用增加了1.5万元,并使施工时间增加了2天。 事故四:在F项工作施工时,因甲方供材出现质量缺陷,乙方施工增加用工6个工日,其他费用1000元,并使H项工作时间延长1天,人工窝工24个工日。 上述事件中,A、D、H三项工作均为关键工作,没有机动时间,其余工作均有足够的机动时间。 合同约定人工费标准为30元/工日,应由甲方给予补偿的窝工人工费标准为18元/工日;施工管理费、利润等均不予补偿。在该工程中,乙方可得到合理的费用索赔有哪几项费用索赔额是多少
