甲建筑公司2012年1月签订了一项总金额为1000万元的固定造价合同，最初预计总成本为800万元，2012年度实际发生的成本为800万元，2012年12月31日，甲建筑公司预计为完成合同尚需要发生成本400万元，该合同的结果能够可靠计量，2012年12月31日，甲公司应确认的减值损失为( )万元。

A．0
B．200
C．66
D．130

答案

参考答案：C

解析： 完工进度=800÷(800+400)=67%，应确认的营业收入=1000×67%=670(万元)，确认的减值损失=[(800+400)-1000]×(1-67%)=66(万元)。

Damaged nerves in the spinal cord do not regenerate themselves naturally, nor even under the spur of nerve-growth stimulants. The reason, recently discovered, is the presence of nerve-growth inhibitors in the spinal cord. Antibodies that deactivate those inhibitors have now been developed. Clearly, then, nerve repair will be a standard medical procedure in the foreseeable future.
Which of the following, if true, casts the most serious doubt on the accuracy of the prediction above

A．Prevention of the regeneration of damaged nerves is merely a by-product of the main function in the human body of the substances inhibiting nerve growth.

B．Certain nerve-growth stimulants have similar chemical structures to those of the antibodies against nervegrowth inhibitors.

C．Nerves in the brain are similar to nerves in the spinal cord in their inability to regenerate themselves naturally.

D．Researchers have been able to stimulate the growth of nerves not located in the spinal cord by using only nervegrowth stimulants.

E．(E) Deactivating the substances inhibiting nerve growth for an extended period would require a steady supply of antibodies.
