同学。。。好认真。。。很欣赏。。。继续努力。。。

; T& h0 ?. s* k" d1 {1.       A和原句的in this肯定不对，SAT中this不能单独存在，记住见到this单独存在一定错呃。B对的，for后面表示原因是一个完整句子，很对嘛！
2.       原句being错（自杀词），A的telling现在分词表伴随应该是在相同时间发生的事情（进行时），后面句子是一个算是客观事实吧，比较陈述的反正是，所以不符。B是Linda的同位语，很简洁，SAT中同位语优先原则知道吧！（要对其敏感一些哦）
3.       这里表示目的的，所以要用不定式，不仅准确而且简洁。改成to catch。SAT中to do很常见，因为简洁原则。
5 n& H  Z* v) B5 r  X6 q4.       这里to是介词，后面要加doing，改成being。这个需要积累，有些adj后面的to不是不定式，要注意啊！
5.       这是介词搭配呃：necessary+for sth…   condition+to sth…
6.       分号相当于and，所以前后句子并列平行。Is one和is another很明显看出平行啊，那看两句主语，前面是driving，后面就得turning off啦！
7.       后面是sth and sth很明显是复数嘛，谓语动词咋能是is嘞？要改are呃。这是个倒装，形容语提前了，但是动词形式还是要看主语的嘛！
% m* \' E' C. Z+ A* D# v0 f8.       原句being自杀，A的whose形容人而前面是city，不对。B中although表示转折，算是一个插入语吧，不影响大局。后面动词要单数因为city是主语。
9 j! v$ p1 e5 A- f. q/ ?5 E9.       这个好熟悉呀！我当年最晕的题（其实就是今年），走街串巷似乎问遍全球的…呵呵…几种解释：becoming放soon后面修饰soon了不对，应该修饰path，所以要把soon去掉；然后就是时态，明显前后不一，这里现在分词表示伴随结果必须和原句时态相符。
2 k/ c& H8 y; i& |10.   原句没错而且平行原则对仗工整的很啊！那个A似乎比较罗嗦，而且听不懂他在说啥，有歧异，还有就是不在不得已的情况下不要随便换主语，还有不要轻易用被动。
* |+ l) U# z$ W3 D3 b11.   时态问题。前面有next Sep了，后面就应是will。这个would没有时态暗示时候不能轻易动用呃。
+ {4 ?0 O! Z0 X5 r% a) C12.   这是代词指代不明确。句子有college还有president，这个its不好定位了。They和its在一个句子里出现很容易模糊指代。答案把主语补充上，和原句构成平行结构很工整嘛，而且比较选项也能看出答案很简洁呃。
13.   现在分词可以伴随表示伴随方式或结果，这个是原因，表示解释的，不能直接explaining。还有就是这个doing指代的也比较模糊，正确答案把主语补充上了，很对哇！
2 l+ w0 r5 O! s& ?) X14.   原句lesser不是比较级而是形容词，后面有than所以错了。A又是物做主语吧，不要呃，那个least还改变句意了…B相当简洁相当准确尤其是那个to do…
$ E8 g3 @; u+ F$ E" J+ ~15.   in a world that后面是一个完整句子吧，所以that就不对了呃，不能做状语。所以要改成where，而且前面是world也表示地点，不会用that的。这个要注意！最好背住！
% F6 K/ f4 u; T9 J9 |! k: K16.   原句是run-on句型错了。你那A是马虎了吧，明明是人，是biographer，你咋给弄成biography了呢？除此之外，这个分号和and都是对的，没有区别。B很好嘛。这个马虎要不得啊，几千块跑香港还是国外去，一定得控制…呵呵…
