重力会让大的彗星受到撞击之后又把小的块儿给吸回去（飞得特别快的除外）变成rubber pile，而那些小的星星受到撞击之后就是monolithic了 因为他们的吸引力太小了，碎片挣脱吸不回来，没办法变成rubber pile。
所以 smaller 会变成 monolithic

就像cr的weaken题。这里只要找出直径大于200的asteroid 旋转的还特别快的就行。
1.直接排除ab
2.忽略大小 直接看转速 c 一周一次 d 一个小时一次 e 一天一次，那就选d最具有说服力可以weaken

太难了

five 之前有个 all but five...所以说的就是“全部的彗星除了这五个”，和下一句的exceptions相呼应。大的那坨星星满足了rubble piles的条件 所以他们是monoliths 有快有慢的

同位语，若概念名词，则指代前面整句。
同位语，若具体名词，则只能修饰最近的名词，如(B)(C)，是950 million的同位语，错误

Not by, but by 中间加入as was the case with

E：sales of fund shares in July were not as low as what中的 what 去掉是不是也是对的啊

这里是否还有平行考点？

感觉是highway is road system 不可以是the greatest road system is highway

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。

D是the reason that应该是the reason why吗？？？！

参与到V公司相对低效的工作占用了经理们太多的时间，那些时间本应该用在V公司的核心业务，说明outsourcing有利

a and b ，不用加 also

并列句之前没有逗号

比较对象：真实情况和科学家以为的情况
a much earlier emergence of complex life-forms和previous thought

The opposite situation, when surface temperatures are well below normal-La Nina-is far less common.
答案应该是E吧？

native species是concrete noun，maintenance是action noun，不会导致不平行吗？还是说此处不需要严格平行？

题目指出：On average, the emergency treatment for an elderly person for injuries resulting from a fall costs $11,000.
答案：A frequent result of injuries sustained in falls is long-term pain, medication for which is not counted among the average per-person costs of emergency treatment for elderly people's injuries from such falls. 意思是治疗长期疼痛的人均费用没有被算在内，即成本可能不止$11,000.
