1. such为什么不能指代borrowers呢？
2. 且我认为such a group表示“这样的一组”，such作限定词限定group
3. 因此我认为 C错在with such a group 是独立主格 ，作状语修饰整句；E错在they的赘余

为什么一个数字只能用一次呢？

The modifier doesn't make sense as a modifier.

The main sentence says that Japan's population IS shrinking. I.e., it's discussing something that is happening at present.

A projected decline is in the future. So, "with a projected decline" can't be used as a modifier, since the future doesn't describe the present.

Note that the correct answer handles the situation by linking two different verbs——in two different tenses——with "and". No modifier.

比较的是生孩子的女性的年龄分布，而不是不同年龄女性生的孩子数量

谁知道有没有无性别者呢。

although不需要什么前后平行

actually, no, it's not essential. the "in contrast to some" already covers that base.

for instance, consider the following:
in contrast to some other restaurants in the area, Les Jardins only serves beer and wine, not hard liquor.
--> this sentence ALREADY implies that "some other restaurants" serve hard liquor. therefore, if you're going to add that reference for emphasis, you should make it a nonessential modifier:
in contrast to some other restaurants in the area, which serve a range of hard spirits, Les Jardins only serves beer and wine, not hard liquor.

for the same reason, you want commas around this modifier. if you don't have them, the sentence actually becomes redundant!

There are a simple reason and misconception as to why people find this question confusing:
--> the 90 degree angle between P and Q seems like it is cut perfectly right down the centre >> to make two 45 degree angles.
--> that's why your brain instinctively thinks the answer is r = sq(3), since the distance seems the same from the left and to the right of the origin!

However, that's the trick to this question and that's why it is CRUCIAL that you train yourself to be highly critical and wary of accepting the simple answer!

Upon closer inspection of the question:

P(-sq(3),1)
Which means the triangle beneath point P has:
height = 1
base = sq(3)
meaning >> radius = 2 (30-60-90 triangle)

毕佬，D选项宾从后面的谓语是不是打错了？flowing ice不应该是不可数名词吗？后面的have是不是应该为has？最开始就排除了D，求解。

1： x=5. median=（15+17）/2=16
2: x 不唯一。

填空題，等於從上述往下推論要一致:狗會幫助狗朋友--->達到加強效果
A---> a familiar person/ an unfamiliar person 引入外來因子，如果成立，反而削弱原先推論
B--->反向削弱，沒狗朋友卻留更多，代表一開始認為狗會幫助朋友的立論有誤
C---> hostilit引入外來因子，如果成立，反而削弱原先推論
D--->appeared uninterested in food引入外來因子，如果成立，反而削弱原先推論
E--->合理，狗朋友在一起就幫助；沒在一起就無所謂

有了which是一个从句，所以需要有谓语动词，C错。

by far多用于最高级，而不是比较级。记住！

ever before 需要用完成时态。

要从语义判断时态

raising修饰cost，导致前半句的核心意思变成city propose sth at a cost，整个句子的意思就不对了，类似 the victory is achieved at a great cost.
at a cost: 以...为代价，以...为成本

题干里面提到了3种钱：assistance，income，supplement，不要把第一种和第三种搞混了
失业人员：每月有政府的补助X。
失业人员如果接受一个比X还少工资的工作：政府会补差价，补到这些人也拿到X。政府的目的在于鼓励公司用便宜的价格雇佣他们，减少失业率。
但是失业人员会这样想，不工作得到的也是X，工作得到的也是X，还不如不接受这种工作的好。
但是如果失业人员工作后再去找新的工作，得到的工资就会超过X，而不工作后直接去找新工作不会得到这么高的工资。那么接受这个工作还是很划算的因为以后就会有更高的收入了。所以失业人员最好还是接受这种工作。

想问B为什么不对？？第一段最后不是用到situation这个词了吗？

A项 在逻辑上，合同商和工程师两个人不会同时去责备他们两者中的一个
E项 one another一般用于“多于两者”的情况，即，
例如一共有三个人，我们可以说：
each blames one another.
这句话的意思是，每一个人责备三者中的一个
如果一共只有两个人，则我们会用：
each blames the other.
the other表示“另一个”
