Answer 1

1、更改为having revised,根据句意有先后顺序。
2、On the ground of 意思“以....为理由；根据”eg.The cutbacks are justifiable on the grounds of cost.削减符合成本方面的考虑。枝扰氏直接在of后加名词或动名词
3、demand做谓语动词时后面语句应该跟虚拟的谓语动词即should+动词原形，这里should可以省略；完整的形式是demand/require/...+that+主语+（should）+动词（原形）+...，所以应该选B
有一些词就是这样的，在此不详列。
4、原句意思是“在过去青年人常向朋友们发送信件，而不是像如今这样发送即时电子信息”，句中强调了时间的对比，故D选项不合适，in the past 和today相对比，在句中的位置上夜要显示出来。
5、这个说实话考察得有点偏，属于词义学上的东西，当然对于高中生而言也不超纲，as a result of 一般后面跟负面的因素，而due to则中性或更积极因素。句中提到是riot，所以结果不好，其原因是队伍长等李旁负面因素。
6、其实是你自己立即出现偏差，在这里novels +that+句子形成一个以that引导的定语从句。是不是很直白！
7、这里没有省略，用much of在这是指south america的国土面积，面积本身当然是不可数的，如时间，eg. Another ten minutes is really a lone time when Sam waited for his father before operation room.
8、这里是时态的一致性问题，前面已经是现在时，整个句子的时态要一直，不能限于意思而忽略时态问题。
9、这里as引猛散导的比较对象是公众所持有的观点，重心在持有“has"上，而不是观点持有和烟草公司的比较上。前后比较的对象要一致。

这里回答得比较清晰，如仍不懂可私下问我。

Answer 2

1. having revised, 有先后晌罩指顺序就要用having done
2.He was dismissed on the grounds of negligence.
+名词、doing 不加that
3. 后面加宾语，好歹也是us,怎么会是we呢？再说表述不如不定式简洁。
4.过去，年轻人上课总是传纸条，而不像现在发短信。
若选D，e-message的谓语就变成了 PASS，应该是SEND，C的分号另起一句说明现在怎么怎么样，send也用对了。
5. 我也不知道，你再仔细看看，是不是有别的不一样。
6.要记住书里的东西用现在时，你写闷旅作文的时候也注意。
7.不是，把SA看成一个整体,MUCH OF直接表示整体的大部分。
8.你觉得可能性不大？要看看整句宴配句子，It is LIKELY that......
9.凡是比较就要结构完全一致，public HAS,前面有谓语，你后面也要有谓语，it作形式主语，DOES和HAS平行。
