Lichens may grow on the bark of a tree in a steaming tropical rain forest, on the bricks of big city buildings, on rocks in hot springs, on wind-swept mountaintops, and in the driest desserts. In the arctic, they provide the principal food for caribou, and they are one of the few plants that grow in Antarctica. They are pioneers, appearing in barren rocky areas and starting the formation of soil in which mosses, then ferns, and then other plants can take root.
Lichens are a partnership of two plants — fungi and algae. The lichen body is made up of a network of fungal strands. In the upper layers of these grow groups of algae. The two organisms live together to the benefit of both, a relationship known as symbiosis. The fungi provide support, absorb water, and shelter the tender algae from direct sunlight. The algae carry on photosynthesis and provide the fungi with food. The algae can live independently and are recognizable as a species that grows alone. The fungi, on the other hand, cannot live apart from their partners. They can be placed in known classes of fungi but are unlike any species that lives independently.
So definite are the form, color, and characteristics of these double organisms that for hundreds of years, they were classified as one. More than 15,000 "species" were named. If these organisms are classified as separate species, it is difficult to fit them into the existing system of classification. But if they are classified separately, these species of fungi seem rather strange. Lichens are a splendid example of the difficulties faced by taxonomists in classifying species.

The word "barren" underlined in Paragraph 1 most probably means _______ .

A.lifeless

B.frigid

C.hard

D.uncovered

20×7年2月1日,甲建筑公司(本题/称“甲公司”)与乙房地产开发商(本题下称“乙公司”)签订了一份写字楼建造合同,合同总价款为4 700万元,建造期限2年,乙公司于开工时预付20%的合同价款。甲公司于20×7年3月1日开工建设,估计工程总成本为 4 500万元。至20×7年12月31日,甲公司实际发生成本1 984万元,其中包括甲公司在订立合同时发生的差旅费100万元,为组织和管理生产经营活动而发生的管理费用60万元。由于客户要求将原设计中采用的铝合金门窗改为采用隔热效果更好的塑钢门窗,甲公司预计 完成合同尚需发生成本2 976万元。为此,甲公司于20×7年12月31日要求增加合同价款 500万元,并与乙公司达成一致意见。
20×8年度,甲公司实际发生成本2 946万元,年底预计完成合同尚需发生530万元。
20×9年2月底,工程按时完工,甲公司累计实际发生工程成本5 100万元(不包括差旅费和为组织和管理生产经营活动而发生的管理费用)。
假定该建造合同的结果能够可靠估计,甲公司采用累计实际发生合同成本占合同预计总成本的比例确定完工进度。甲公司适用的所得税税率为25%,预计未来期间不会变更;税法规定计提的资产减值损失不允许税前扣除,在实际发生损失时才允许扣除。甲公司预计未来期间能够产生足够的应纳税所得额以利用可抵扣暂时性差异。
要求:根据上述资料,不考虑其他因素,回答以下问题。

下列有关20×9年2月底甲公司建造合同完工时会计处理的表述中,不正确的是 ( )。

A.应当按照合同总收入扣除累计已确认收入后的金额,确认为20×9年合同收入

B.应将“工程施工”科目的余额和“工程结算”科目的余额相对冲

C.若之前存在因减值而确认的存货跌价准备,则应将其转销,并冲减资产减值损失

D.若之前存在因减值而确认的递延所得税资产,则应将其转回,并冲减所得税费用
