39. sword manufacture fficeffice" />
V2 from zhoutanlu
关于sword manufacture,这道题目有点难度,关键我最后时间不够了,没仔细看,讲到contemporary sword manufacture反而利用了古代制剑术的刀片的缺点,这个是结论,问得是加强也不知道削弱。答案里面有铁的原料啊什么的,记得的同学补充一下吧。
40. hip replace 的原因
V1 from fivered
一些科学家猜测有关引起要hip replace的原因,有的人认为是有种可能是由于胃的酸性使得钙的吸收减少造成hip变坏,还有的人认为是因为血液中的什么吸收不好造成钙的流失的。 问支持后者的结论而weak前者的选项?
我选的是个什么因为其实胃酸不能吸收破坏钙。
小组说:1.stomach acid 导致Ca吸收不好 2.血液中啥导致Ca吸收不好
support2,weaken1 是血液的问题,胃酸没不好。
41. Gortland的进出口(OG原题!)
202.Gortland has long been narrowly self-sufficient in both grain and meat. However, as per capita income in Gortland has risen toward the world average, per capita consumption of meat has also risen toward the world average, and it takes several pounds of grain to
produce one pound of meat. Therefore, since per capita income continues to rise, whereas
domestic grain production will not increase, Gortland will soon have to import either grain or meat or both.
Which of the following is an assumption on which the argument depends?
(A) The total acreage devoted to grain production in Gortland will not decrease substantially.
(B) The population of Gortland has remained relatively constant during the country’s years of growing prosperity.
(C) The per capita consumption of meat in Gortland is roughly the same across all income
levels.
(D) In Gortland, neither meat nor grain is subject to government price controls.
(E) People in Gortland who increase their consumption of meat will not radically decrease
their consumption of grain.
