Per Capita Expenditure=overall use*product price/population
PCE上升，use不变，那么需要population下降或product price上升；
product price上升：1. 升高原产品价格
2.直接开发价格更高的新产品

-Airport的结论是建立在怎样的基础上？
-居民完全有能力预知风险，他们应该自己负责机场噪音的影响。
B.如果是20年之前搬来的居民当然有资格投诉机场，但20年之内搬来的都是已知机场噪音后作出的选择。

错选A，没有认真审题目里写的是哪个地区。

如果题目问的Weaken，一定要找能切实损害到方案可行性的。
目的：增加过路费以提高收入
A.可能有反对，但不一定会阻止方案通过
B.需要花钱调整机器，但这个钱之后可以收回来
C.通勤者买更多优惠券，这个差距之后也可以弥补
D.20%commuters直接换路线，这意味着增加过路费可能完全无法提高收入
E.irrelevant

B. all of which引导的必然是定语从句，其使得整个句子缺少谓语动词。另外，划线部分身后的代词its的指代对象必须为单数名词，这造成了其在本题中没有指代对象。

"the increase in X" means that X itself has increased. therefore, "the increase in the previous year" doesn't make sense, because the implication would be that the previous year itself had increased (what would that possibly mean?).

"the increase of TIME PERIOD", by contrast, means exactly what it should mean in this particular instance.

E. the number是不可数名词，所以至少应该改为much;
double as much as the increase of需改为double the increase of。这是因为，当“非数字物体（即，这个名词本身没有纯粹的数字概念，例如dogs、cats等绝大多数名词）”比较时，我们通常会用double(twice) as much as或double(twice) as many as，例如：
twice as many dogs
double as much water
但是，当“数字”比较时，我们不能加as many或as much，例如：
twice the increase
double the decrease
显然地，增长和下降本身就是数字的概念。因此，不能用double as much as the increase of;

哦哦看错了，答案是D

"laws to require..." isn't a correct idiom if you're discussing the actual text of the laws themselves. if you were discussing the ultimate purpose of those laws, then this could be idiomatic;1. laws specifying long jail sentences for drunk drivers --> correct 2.laws to specify long jail sentences for drunk drivers --> incorrect ) 3. laws to discourage drunk driving --> correct (this IS actually the ultimate purpose of the laws)

这道题为何不是D？
(2) The total number of bulbs in the first box is 9 more than the total number of bulbs in the second box.
第一个盒子的灯泡总数 是 9 + 第二个盒子的灯泡数，这明显可以求的呀？

C选项：动词die是点动词（所谓点动词，就是那些开始即完成的词），由于点动词根本就没有持续的时间，所以开始就意味着到达了终点，自然不可能用ing的形式。（参考名词和ing的区别）

in general, "so [adj/adverb] that [complete sentence]" is used when "[complete sentence]" has a DIFFERENT SUBJECT than the original sentence.
e.g., When I came back from vacation, I was so tan that my friends didn't even recognize me.
(subject changes from "i" to "my friends")

if the subject is still the same, then "so [adj] as to [verb]" is a more efficient way to write the construction.

this sentence:
they (= major economic shifts) are unable to be distinguished...
！ we're not actually talking about an "inability" possessed by the economic shifts themselves.

i also find something a bit awkward about the use of "unable" to describe something that's not actually an inability of the subject.

here's what i mean:

this plant is unable to perform photosynthesis.
legitimate, because this actually describes an inability of the plant itself.

该提答案错了吧
