提问:

Most of the world's supply of uranium currently comes from mines. It is possible to extract uranium from seawater, but the cost of doing so is greater than the price that uranium fetches on the world market. Therefore, until the cost of extracting uranium from seawater can somehow be reduced, this method of obtaining uranium is unlikely to be commercially viable. Which of the following would it be most useful to determine in evaluating the argument? A.Whether the uranium in deposits on land is rapidly being depleted B.Whether most uranium is used near where it is mined C.Whether there are any technological advances that show promise of reducing the cost of extracting uranium from seawater D.Whether the total amount of uranium in seawater is significantly greater than the total amount of uranium on land E.Whether uranium can be extracted from freshwater at a cost similar to the cost of extracting it from seawater

提问:

老师,这道题怎么解的?我自己的理解是,速度慢的机器有1到3台,把每台多出来的1小时加在一起除4,求得的平均值就是小数点后的数字。所以求的平均值最小是0.25不可能是0.2因此选项A,7.2是不可能的。但是不知道这道题是不是这么理解的。

老师,这题答案是D,但我觉得是C。题中说大于10小于100的整数,应该是89个,掉到过来98+9,个位数是7

提问:

这个是Tina 老师在语法课上讲的一道题,不知道为什么搜不出来。想问一下,正确答案B 选项中的begun为什么不是过去分词引导的状语从句修饰the autographed quilt? Tina 老师在课上讲的是:begun是就近修饰名词fad的,我就很迷茫。我一直记得您讲过过去分词和现在分词作状语是修饰不到SVO 的O 上的,那这个为什么例外呢?谢谢您!
