D选项：two big reasons
1) "the economy of Britain, France, and Germany"
--> illogically implies that these three countries share only one economy. (note that the correct answer correctly uses the plural "economies" to refer to the existence of three different economies.)
2) "with the unemployment rate that has remained"
--> implies, without justification, that the dutch economy is the ONLY economy with an unemployment rate that has satisfied this criterion.

一方在UDS销售，另一方不在UDS销售，这样作对比不是更能比对出结论吗？

注意：题目中的some是adj表示大约的意思
some 4000==》其实指代的是4000 drive-ins ，是一个可数名词

ron:"twice as many", "one-quarter as many", etc. are not only acceptable as idiomatic expressions but also extremely common in the english language.
since this idiom is present in the correct answer, which was written by gmac, IT IS CORRECT.
end of discussion.

amount ==》n .通常去修饰不可数名词（但是amount这个词本身是可数名词的）==》 a large amount of work, money, furniture //
Food was provided in varying amounts.
amount也可以用作v.总计 达到 Our information doesn't amount to much 我们的资料有限

drive-in n. 免下车餐馆,免下车电影院 drive-ins 是复数了...
at the height of sth 在sth的鼎盛时期

shelter: intransitive verb
«person, animal» 躲避 duǒbì

The culprits for service-sector productivity stagnation are the forces—such as corporate takeovers and unnecessary governmental regulation—that distract managers from the task of making optimal use of available resources.

stagnation——improvements 取非

if budget deficit were lower, interest rates would be lower too, thereby increasing investment in the development of new technologies, which would spur productivity growth in the service sector.
discrepancy: in productivity growth between the manufacturing and service sectors.

communal=community as a whole

注意从句的修饰！！不是N是3的倍数，而是原来这个数

1. fewer and less区别
2.amount 不可数

补充 as many 的用法

1. as many的用法(摘自Longman):
as many=a number that is equal to another number 表示同样的数字
They say the people of Los Angeles speak 12 languages and teach just as many in the schools.
in as many days/weeks/games etc.
A great trip! We visited five countries in as many days (=in five days).
*: "twice as many", "one-quarter as many", etc.都是非常常见的用法，记住这样的表达。

这道题最开始做的时候 完全是 主观臆断的排除了cde...只留下了ab ...

当想用being+adj的时候 一定要先去想一下是不是有更好的表达方式==》定语从句 / v-ed / 直接的adj修饰 / 同位语修饰

① , despite being offered $1,000 to do so.《==注意看 显然这个修饰需要main clause的主语直接就是那个人
②since so存在语义重复
③you should avoid "being" when expressing the IDENTITY or CHARACTERISTICS of some individual or thing.
otherwise, evaluate it on the same merits as you would any other verb

ron： first, i'm about 99% sure that we are not allowed to use "ones" to refer to people.

second, i'm also about 99% sure that "THE ones" must refer back to "THE some other noun".
