67. 就记得个1997年7月第一个星期not only 是美国独立日，but also 中国什么什么的（它没考 not only， but also），但是中国的这个英国殖民地回归 Greater than 美国的那个，后面有than for /than those for/..of....美国之类的（我选的挺没把握的，看谁来考古）
77. 考了一道独立主格，populated by..., each,,, each后面一定要跟单数
78.一个not only, but also的平行，选那个not only to, but also, to
79.有一道主语是brain scans,谓语一定要用复数
80关于which 还是 ing形式的题
81.还有一题是一道全划线的题，我最后选的结构是：同位语在开头，然后是主句
74. 还有一个说brain can restrain of ××， so experience can be as well. 这个我想了很久，因为我不知道后面那个××是什么意思，好像是个turaf还是什么单词，但是我觉得experience应该不能做主动，所以选了can be as well那个。不知道对不对。
75. 还有一个是××× +动词+宾语，establishing and ××-ing... 反正我觉得后面两个动词都是修饰前面的那个句子的，不是那个宾语
76. each of which×××
71.(discription about a kind of crop), they are short stemmed, ... and can be collected more easily than (the previous version)
they are short stemmed, can... and be collected more easily than can the precious version.
Now I think the second choice makes more sense, but I am not sure cause I can't remember clearly right now
72．好像考了一个which..., but which is thus unable....,这个我很纠结，因为有一个选项是which...., and which is unable...我最后选了前面那个，觉得but有强调的意思，但是thus又感觉很怪。
73．还有一个是california is the first state把××课程又重新在学校开动，..ing and ing, ...ing...反正三个ing的动词，一定搞清楚逻辑关系。
68．语法考了那个those attending ...什么的，if not, ...你把表邮回来那个，我选最后一个if....if....
感觉很多平行，and 前后注意ing 和ing 的平行，我记性不太好了。。
69． Things would be different if ... had been...
Check the tense please
70.as many ... as the number of firms, employees and ...
the difference of the answers are the number of or the amount of...Please check
