第三步：挑战权威之后带来的benefits。

This news spread through the black community. 1People felt it was the time for them to do something. After a conversation with several ministers and civic leaders, the group decided to organize a boycott. On the next Monday, the boycott succeeded----no black people took buses in Montgomery, which 2made they decide to continue the action. 3People formed an organization call MIA, and elect Martin Luther King as their president.

问题：1 这句话太空了，而且和前文的逻辑关系也不是很清楚，建议加上Rosa的举动鼓励大家团结起来争取利益。

2 应该改成make them decide to…不过值得一提的是make 这个单词实在是比较土了，建议换成enable sb. to do. sth./或是render sb. adj 这两个概念。

3 继续行动，和建立组织之间严格说来还有一个小步骤，也就是为了让行动更有效果，建立了……

修改：

The imprisonment of Rosa Park discouraged and infuriated the black, who had been swallowing their anger before this incident. This time they were stimulated to rebel, rescuing the brave woman Rosa Park and more importantly wining their equal rights as an American citizen. Their plan of challenging the white（点题,引出如何进一步挑战） began with a conference composed of several ministers and civic leaders, who decided to organize a boycott among the black, namely, refusing to ride the city’s buses until they were treated with the level of courtesy they expected, until black drivers were hired, and until seating in the middle of the bus was handled on a first-come basis. Moreover, in order to win the battle more effectively, the black formed an organization call MIA and elected Martin Luther King as their president. Their protest lasted over a year, ending when the United States Supreme Court ordered Montgomery to abolish the bus law. （这是挑战之后的成果，废除了公交法）

第四步：例子论述结束，进行议论，把观点和例子结合起来。

If those black people had never fought for their rights, they would still sit 1on the back of the bus, and 2they had to give up their seats whenever white people ask. 3If they had not challenged the white people, who are authority to them, they might still live at the bottom of society.

问题：这个议论写得还是比较精彩的，用的是虚拟语气，从句和过去相反，主句和现在相反。

1 处有问题，坐在汽车后部？ Take a seat in the back of the bus.

2 处的they had to 和之前的they would sit 并不是完全对等，我们可以改成： They would have to take a seat in the back of the bus and give up their seats when the white section was full. 其次if 如果做虚拟，可以做结构省略，had those black people never fought for…

3 生活在社会底层这个表达还是略有点中式。

Had they never challenged their authority, the white, they might still live at the foot of the social ladder.

4 还有一个小问题就是在不写结尾段的情况下，建议在议论部分明确的把你的观点再重申一下。

修改：

Had Rosa Park never refused to give up her seat（概括例子）, the black would still have to take a seat in the back of the bus and give up their seats when the white section was full. Had Rosa Park never challenged the authority for equal rights, the black might still live at the foot of the social ladder.

Thus, it is imperative to question the authority behaving irrationally. （重述观点）

全文总结：

1 SAT作文的开头段三步走，一明确指出观点，二解释为什么，三做出结构提示，即下文举什么例子。

2 中间段的例子主要由论述和议论组成。

论述过程中要围绕观点来展开，分析好题目之后确定要细化的内容。本文要细化的是权威的所指，为什么挑战，怎么挑战以及挑战之后的结果。

议论指的是把例子简单总结，结合观点。

3 高分关键：1）细节充实；2） 逻辑清楚；3） 语言准确。

其中第一点是可以短期提高的，给大家提供一些参考书：《维基百科》、《美国历史重大事件及著名人物》（郝澎）（此书是中英对照） 、《外教社人物传记丛书》（英汉对照）。 后者是我强烈建议的，内容短小精悍，包括了很多熟悉的人物，比如比尔·盖茨、戴妃、莎翁、泰格·伍兹等等。大家可以选取1-2本，一边看一边做摘录，同时多做思维练习。

4 Practice makes perfect. 相比阅读部分，作文部分的提高还是很快的，大家把题目分好类之后，按类别准备例子，然后限时练习。
