推荐答案:
D的最大问题是Greg没有谓语，who引导的是一个定语从句，这样一来，整个大句子没有主句。如果把who以及前面的逗号去掉，则D为最佳选项。

From that moment onward, politics and history became my passions. In school we had been taught that there was no society freer than the United States, but that was only part of the story. By reading about the political struggles of minorities, women, blue-collar workers, and others, I learned that freedom is not something you're given, it's something you have to fight for. And once you win it, you have to make sure no one tries to take it away again. I learned somuch from Mrs. Fletcher that day, and our conversation transformed me forever. I developed an awareness of the world around me, became less self-absorbed, and took a very important lesson from the past: progress begins with people who choose to stand up for what is right. It was like I'd had a rebirth after talking with Mrs. Fletcher, and that is why I agree with the idea that the most memorable days of our lives are those in which we learn something new about ourselves and experience an awakening.

随进度精讲语法，即按正常的教学进度将提前略讲的语法内容不断深化和扩展，着眼于应用。如略讲现在完成时，学生只知道 I have worked here. I haven worked here. Have you worked here? Yes, I have. No, I haven。 四种简单形式。精讲时，要重点突出since, for等时间状语在现在完成时中的应用。
3.阅读与词汇、语法教学同步进行。

4分作文： Some people would say that something that is not successful does not have any value. I would have to disagree with this statement. Sometimes, things that are not successful still have some value. For example, the Columbia space shuttle and the Vietnam War were not successful, but they had value. Thus, it is true that something not successful can still have value. For instance, the Columbia disaster. Columbia was destroyed in an accident when the shuttle tried to re-enter the atmosphere. This accident was a horrible failure and many people were very upset by it. The value, though, comes from the new way in which we now look at things. Because of Columbia, the space program now know what is wrong. Hopefully, they will change it. Vietnam is also an example of something not successful. We went to Vietnam in an attempt to get rid of communists. Thewar went on for a while, but we were not able to win. Many soldiers were killed and the public were very angry about the whole thing. Soon there were many protests across the country and college students especially became active against the war. By the time the war was ended the people were very upset with their country. These two examples show that something not successful can still have value. As we have seen, both Columbia and the Vietnam War were not successful. Yet, we got something of value out of them. 【点评】 开始段落把中心观点讲出来了，并且也有thesis statement。
