people's 表示人们已经有的东西，不能在加进人类的记忆力，they 不能指代所有格里的名词

for example （后面只能加一个例子）vs such as （可以加多个例子）
D： working year round 做定语限定professional clammers, 导致比较对象不对

C的并列关系错误

E： 如果时间状语是由since引导，那么谓语动词必须以完成时的形式出现

代词them的指代对象有歧义，两个名词都可以发出这个动作

E:including 只能是介词，不是伴随状语，做定语修饰example，逻辑错误

literature没问题，但history感觉怪怪的。即使第一段提到了“history”这个字眼，但文章似乎对历史的描写……没有啊根本。（牢骚: 就连动词的过去式基本上都没看到..haha )

对于A of B that 结构的解释BY RON： it should be 'includes', because the only noun that makes sense as an antecedent here is 'group'.
after all, it's the group that 'includes' its members. if you say 'hoofed mammals that today include cows, camels, ...', then the literal interpretation is that you're talking about hoofed mammals that actually contain cows, camels, and so forth as parts of their bodies! now that would be scary.
and remember that you MUST use the literal interpretation of whatever sentence you happen to be reading; you're not allowed to use words in any manner other than the most literal and formally correct possible.

文章中说了‘ while some manufacturing jobs have been lost due to foreign competition, many more xxxxx ’ 意思说competition确实造成了一些lost但是大部分的lost和他没关。但不管怎么样它也是众多direct cause之一。

仔细读题！ H assist files to taste H 显然不对，
assist sb in doing sth
those of others也不对

grains of pebbles错误

前面的解说有问题啊，第二个不充分不是因为r=1，如果r都等于1那就是充分的，第二个不充分是因为存在6和10这种情况，r可能大于1（即2）可能不大于1（即1），所以不充分。

at any time没有排除现在

A选项：分词短语being concern that the bank's loans will help foreign producers compete with American businesses只能做congressional passage的定语，但是本题的意思是美国国会声明（cite）一个担心，而不是声明一个障碍。
D选项：an obstacle to congressional passage变成了the concern的同位语。但显然地，concern并非本身就是an obstacle，而是美国立法者将concern声明为一个障碍，即，obstacle必须作为宾语的补足语。

the subject is "sports medicine programs".
be geard toward doing sth.

as作比较时连接两个句子；like可以直接跟名词做对比。

D: ----Problem1: 描述conrete subjects不用不定式，而是定语（从句）限定修饰；
----Problem2: "which is"is unnecessary and ugly , 同位语较优！
