Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream. However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur. These results provide support for researchers' prediction that naltrexone will turn out to be toxic to certain types of bacteria.
Which of the following, if discovered to be true, would most seriously weaken the support for the researchers' prediction?

正确答案: B

重复的狗就忽略了,放几道考之前我没看到过的。


数学:1、a1=1, an=an-1+n, set为1,3,6,10??, 问the sum of two consecutive terms可能是下面哪个?(注:这里的n和n-1为下角标)          解题思路:把以上数列两两相加,与答案对照。


         2、有个人买了70pounds的两样东西(暂且叫ab吧),问这70pounds一共花费多少钱?条件1是a每pound多少钱,条件2是b每pound多少钱(两者价格不一样)
         解题思路:e吧!


         3、一个人毛收入a, 缴纳所得税b(百分比),将缴纳完之后的钱存入c到银行,剩下的钱再捐d(百分比)到福利机构,问用abcd表示还剩的钱。
         思路:照列就行了 没什么tricky的。


        4、一家公司想通过控制成本,提高selling price来增加profit,从本来的10%到20%。已知本来的selling price是22,问提高的selling price是多少
        思路:两个式子列一下,先求得cost是20,再得增加的price是2。


        5、最贵的5本书平均价格是4,最便宜的5本书平均价格是3,问一共书的平均价格。条件1:买了11本。条件2:最贵的一本是6刀,最便宜的是一本2刀
        思路:当时没思路,现在也懒得想了。就知道单独条件1肯定不行啦。感觉单独条件2挺靠谱!求高手来解答了??


逻辑:1、20-30岁的人喜欢可乐,60+岁的人喜欢咖啡。现在有个城市在未来,20-30岁的人减少,60+岁的人增加,所以得出可乐的销售减少,咖啡增加。weaken
         有两个相关选项吧 d是说preference跟所处的环境有关,e是habit在20岁左右的时候形成,并且change little。


         2、将a物质注射进小白鼠,这个物质就会invade白鼠的血液使得blood poisoned,现在将a物质和b物质一起注射入白鼠体内,发现情况就没那么严重。推断出什么
         有个相关选项是 b物质阻止(还是减缓)了a物质侵入血液。另外忘记了!


作文:有个公司想实行cost-saving model,执行如下:让senior employees来培训apprentice,这样可以免去training program带来的expensive和time-consuming


( 能想起来的就这么多,最后祝各位g友蒙得全蒙对!??)

楼主的最后一道逻辑JJ跟GWD的一题很像啊,求确认
GWD-TN-20
15. GWD-29-Q40
Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream.  However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur.  These results provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria.
Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?

A.    After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.
B.    Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
C.    Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.
D.    The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine.
E.    Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice.
