公量计算。

澳大利亚某出口公司向中国出口羊毛，在合同中规定按公量计算，公定回潮率为11%。货到目的港净重为20公吨。经抽样，已知实际回潮率为15%。

要求：计算其公量，并写出公量计算公式。

答案

参考答案：

解：公量=[商品实际重量÷（1＋实际回潮率）]×（1＋公定回潮率）  = [20公吨÷（1+15％）]×（1+11％） =19.304公吨

所以公量为19.304公吨。

单项选择题

The more television children watch, the less competent they are in mathematical knowledge. More than a third of children in the United States watch television for more than five hours a day; in South Korea the figure is only 7 percent. But whereas less than 15 percent of children in the United States understand advanced measurement and geometric concepts, 40 percent of South Korean children are competent in these areas. Therefore, if United States children are to do well in mathematics, they must watch less television.
Which one of the following is an assumption upon which the argument depends

A．Children in the United States are less interested in advanced measurement and geometric concepts than are South Korean children.

B．South Korean children are more disciplined about doing schoolwork than are children in the United States.

C．Children who want to do well in advanced measurement and geometry will watch less television.

D．A child’s ability in advanced measurement and geometry increases if he or she watches less than one hour of television a day.

E．(E) The instruction in advanced measurement and geometric concepts available to children in the United States is not substantially worse than that available to, South Korean children.
