高二是高中学习的关键时期，不仅课程任务重，而且很大程度上决定着学生今后的发展方向，以及能否考入理想的大学。有着丰富教学经验的老师，向大家传授高二各学科学习技巧，希望对高二学生掌握良好的学习方法、提高学习效率有所帮助。以下是英语学科的主要学习方法。

　　英语词汇精讲：need的主要用法

　　didn't need to do表示： 过去不必做某事, 事实上也没做。

　　needn't have done表示： 过去不必做某事, 但事实上做了。

　　John went to the station with the car to meet Mary, so she didn't need to walk back home. 约翰开车去车站接玛丽，所以她不必步行回家了。

　　John went to the station with the car to meet Mary, so she needn't have walked back home. 约翰开车去车站接玛丽，所以她本不必步行回家了。 (Mary步行回家，没有遇上John的车。)

　　典型例题

　　There was plenty of time. She ___.

　　A. mustn't have hurried　 B. couldn't have hurried　　C. must not hurry　 D. needn't have hurried

　　答案D。needn't have done. 意为"本不必"，即已经做了某事，而时实际上不必要。

　　Mustn't have done 用法不正确，对过去发生的事情进行否定性推断应为couldn't have done, "不可能已经"。 must not do 不可以(用于一般现在时)。

　　三步骤让你在看电影中轻松提高英语水平

　　Many people effectively learn English from Hollywood movie. Yet, you can see some friends, who watch thousand of hollywood movie, do not speak any words!! Right, the thing is you don't just watch it but you have to watch by learning purpose to create more useful entertainment.

　　很多人一边看着好莱坞的电影一边就把英语(论坛)学好了。但是也有些人看了几千部好莱坞电影，还是一个字都不会说!!对了，关键在于你不能只是看着玩，还必须抱着学习的目的认真的看。

　　The steps may annoy your emotion but if you want to learn English you better follow below steps. Otherwise, you may lost your time and effort without nothing.

　　下面这3个步骤也许会让你觉得不爽，但是如果你真的想通过看电影提高英语的话，你最好还是遵循这3步，否则你要么浪费了时间，要么浪费了精力，最终一无所获。

　　Step1: Watch soundtrack movie (of course!!) and watch it with the subtitle on at the first time. Your eyes and ears should work equally at this stage. Try to understand the theme and the main idea of the movie.

　　第一步：看有声电影(囧不是废话嘛~)，第一遍的时候带着字幕看。这一阶段，你的眼睛和耳朵应当同时工作。试着理解片子的主题和大意。

　　第一步：看有声电影(囧不是废话嘛~)，第一遍的时候带着字幕看。这一阶段，你的眼睛和耳朵应当同时工作。试着理解片子的主题和大意。

　　Step 2: Watch it again, still with subtitle on, but now try to minimize the use of your eyes on the subtitle. Listen as much as possible and look at the subtitle only when you really do not understand. Skip all small detail at the first time and slowly increase the amount of learning by decreasing the number of time you stop the movie.

　　第二步：第二遍看，还是带着字幕，但是尽量少看字幕。努力用耳朵去听，只是在实在不懂的时候再看一眼字幕。刚开始的时候忽略掉听不懂的细节，不要一遇到听不懂的就暂停。然后慢慢的多听几遍，试着越来越少的暂停。

　　Step 3: Watch it without subtitle. It sounds tough but believe me, after enough practice at the first two steps, you will find it easier to watch the movie in pure English.

　　第三步：去掉字幕看。这听上去很难但是你要相信，只要你在前两步练习的足够充分，你就会发现去掉字幕没有想像的那么难。

　　You may need to spend sometime to pass the first two steps. Do not reach the last step to early because it can greatly discourage you. However, if you reach it when you are ready you may never imagined that English is such a piece of cake for you.
