我也来两道prep的数学...

prep的数学真刁钻。。。555

1、问t^2+5t+6余几

（1）t除7余6

（2）t^2除7余1

答案d

我选的c

2、5个不同的正数的数学arithmetic mean >=30?

(1)each of the integers is a multiple of 10

(2)这5个数的和是160

答案d

我选的b

记得上次有个mm说她错了7个还50，我今天错了9个也50。。。。难道prep也有测试题。。。

jenniferdsb

谢谢楼下的MM,allen和kevin都说了N遍了,我还是没想清楚,汗...

但你这第N+1遍让我豁然开朗,嘿嘿

楼上的mm，题目中已经把x+5放在分母上，他就不会=0

(2)可以推出arithmetic mean >=30偶们都知道,就省去不说了

(1)关键在于对 multiple 的理解, multiple 是倍数,文中已知是5个不同的正数,所以这5个数最小是10+20+30+40+50=150

这5个数的arithmetic mean =30

（1）t除7余6

（2）t^2除7余1

什么叫  t^2+5t+6余几？

一道GWD-7-40 SC: XY给的答案是D, 可偶觉得是A, 查了以前的讨论,没有结果

还是觉得我们大队的人最牛,所以决定贴在这里,大家帮看看啊!

Q40:

Since February, the Federal Reserve has raised its short-term interest rate target five times, and because of the economy’s continued strength, analysts have been predicting for weeks that the target will be raised again in November.

 

1. because of the economy’s continued strength, analysts have been predicting for weeks that the target will

2. with the economy’s strength continuing, analysts predicted for weeks that the target

3. because the economy continues strong, analysts predicted for weeks that the target would

4. due to the economy’s continued strength, analysts have been predicting for weeks that the target

5. due to the fact of the economy’s continued strength, analysts predicted for weeks that the target will

A，because of表达不如because简洁，analyst后面的时态不佳
B，with修饰作用和analysts不匹配 continue一般不用进行时，或者分词形式
C is the best
D，due to表示原因不如because，analyst后面时态不佳
E，due to表示原因不如because，will与前面predicted不匹配
OG里面有两题是predict，后面都是that引导从句，并用will
注意这里前面时predicted，所以后面用了would
首先because of后面只能跟简洁的名词，象这样有又是所有格又是修饰成分的不行，
另外关键的一点是要用would因为是predit预测，would 是有虚拟的含义
其实这样的题目不难，他都would都出来了，大家应该对这个比较敏感，为什么他出would啊，明明前面有will这个其实就是提醒大家注意再读句子，所以偶一贯强调，有差异的地方就是考点！！

最后那句话是Sinogigi写的，是个N前辈来着。她的看法你可以参考一下。

还有啊，有人曾经提到过due to=caused by，你可以用这个代进去看可不可以。很快DE可以排除。

我支持A

due to用在这里不好

认为A中的Strength用的不好。3M仔细体会一下。

mymengming

because the economy continues strong, analysts predicted for weeks that the target would

because of是不如because好,但是这里的continues strong 不好吧

predicted for weeks好像也不是很好
