9.17回馈放狗

yamyam

一站用来练手，理所当然地跪了。Q50，V就不说了。数学基本没啥做，全部都在考前练了寂静，碰到了好几道原题。特来回馈放狗，为下次攒人品~~

数学
1. DS：a>b>c>0，问c<3否？（也有可能是c>3）
    条件1： 1/a<1/3（符号方向还是不记得，有可能是反的。构筑算出来a<3，可以推出来。）
    条件2： 1/a+1/b+1/c=1 （这个条件纠结了很久，最后答案选了D，不确定）

2. 补充寂静49题。

DS：给一堆人做疾病检查，For what percentage of people能得到correct result（其实就是问一项检查，在一堆人里，能得到正确检查结果的人百分比是多少）

条件1：对于有病的人来说，检查正确率是90%；对于没病的人来说，检查正确率是 92（数字可能有偏差）

条件2：这群人里，8%的人是有病的


构筑应该是选了C，两个合起来能是sufficient的。

3.y=x^4-16x^2这条曲线和x轴有几个交点。直接令y=0，算x就好。

4. DS：问n能否被6整除
条件一：n除以36，余数是27
条件二：n除以3，余数是xx
这道题记不住具体数字了，需要补充，反正也是考余数知识点的

其他的就记得不是很清楚。重点考察的题型有，余数+公因子，我碰到了起码5道以上。寂静里也有类似的了，不熟的需要多看看。还考了几道工效的题，记住【工作量/效率=时间】这个公式就行。

IR
考前一道题都没做过，最后5分。大部分是数学题，感觉对于大部分人来说应该不难。
[size=14.6667px]最难的一道是说设计短问卷。有一道题是固定不变的，其他三道题每次随机抽取。然后给出了一个表格。第一列是各题的编号，第二列是这个题总共被用了多少次，第三列是最近一次被用是几次之前的事。
[size=14.6667px]然后问题有两三个。第一个是对于QuestionB,[size=14.6667px]QuestionE,[size=14.6667px]QuestionF,（编号乱说的）从两个选项“有可能出现在下一次问卷中” “不在下一次问卷中”中选。其他的记不住了。因为没复习过IR，不太知道这个题属于什么套路。大家随意感受一下。


作文
一个国家的旅游发展官员写给经济部长的memo里提出，因为办了足球比赛，旅客数量比三年前显著增多。为了tourism的发展？提议应该申请主办另一场运动赛事，这样可以帮助tourism发展，同时对经济有帮助。


Verbal做的很烂，估计也没啥参考性，以下不看也罢。
阅读撞上了三篇寂静。第一篇R&D，第二篇两个地方的Recession，第三篇是看不懂的女性雕像……第四篇忘了。SC常考的考点是主谓一致，平行结构，对比。（不过总共也就这么几个考点……）记得最清楚的一道题，划线部分考了xxx lacked skills to/for/in xxx，…… be restricted to do/doing sth。感觉那道题的选项变化主要就在这两个部分，最后我也不知道应该选哪个，大家可以查一下这两个搭配上有没有什么讲究。。

摘自某论坛上的讨论 https://ell.stackexchange.com/questions/53141/restricted-to-do-something-from
关于restricted 的讨论



I have a question.

Restrict to do something and restrict from doing something have the same meaning?

for example,

I am restricted to smoke one cigarette one day I am restricted from smoking one cigarette one day.

Are those sentences the same meaning or not?

I just had an argument with my colleague over this topic.

I think restricted to do something and restricted from doing something are different. please help.

These are quite different.

In the first example, to is making restricted mean something like limited:

I am restricted to smoking one cigarette per day.
This means:

I am limited to smoking one cigarette per day.

The other example, from is quite different:

I am restricted from smoking one cigarette per day.
This would literally mean the exact opposite:

I am not allowed to smoke one cigarette per day.
The general understanding is that it's saying you can not smoke cigarettes at all but it could also be interpreted as being allowed to smoke two or more cigarettes, but not just one.

I'd argue that, in AmE, people wouldn't generally use this form.
