曼哈顿讲平行那章说，linking verbs are parallelism markers. To read is to feel
[infinitive phrase] is [infinitive phrase]

read of 了解到

A项
1）比较对象有误
2）had anticipated过去完成时并没有过去时点作为背景，不正确
C项
1）结构上没有错误，但是划线部分并没有和未划线部分形成转折关系
the spraying can be carefully planned, but accidents, weather conditions, and pilot errors 如果这里跟着are the cause of就看不出来转折关系，所以应该用cause larger deposit
2）过去完成时时态错误
D项
1）weather conditions that are not foreseeable和unforeseeable weather condition表达的意思不一样，例如：
the book is not touchable.描述的是书的一种特征，他们是不可触摸的
the book is not touched. 描述的是一个事实，这些书没有被触摸过，但并不代表他们是不可触摸的
本题讲的是“没有被预见到的天气情况”，而不是“不具备可预见性的天气”
E项
1）比较对象不平行
2）过去完成时时态错误

B项 try 和recover不应该是and连接的平行关系，应该是try to recover
C项 recover A from B是固定搭配，不能换成out of
D项 try后面不与for搭配
E项 to do 多余

这题和manhattan那个例句不一样，例句supposed修饰ancestor逻辑不符合，但这里就是要修饰ancestor，表示不确定是不是ancestor，而不是确定了ancestor不确定是不是地中海的

2: m(m+n)=odd m只能是odd-m是even的话这个条件就不成立。 m=odd. odd*n=odd-odd^2=even even/odd=even. 所以n是even。

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
