 重点句型解析
 1. Could you please clean your room?（1）“Could + 主语 + please + 动词原形 + 其他？”这一句型相当于“Could + 主语 + 动词原形 + 其他，please？”意为“请……，好吗？”。这两种句型均表示礼貌的请求，语气委婉，客气。其中could在此句中不表示过去，而表示说话人的语气委婉。因此回答时，不能用could回答。例如：    Could you please help me with my English?    = Could you help me with my English, please?    请你帮我学英语好吗？    －Could I have a look at it, please? 请让我看一看它好吗？    －Certainly！当然可以。 2. They should …in order to get good grades and get into a good university.（1）本句中的in order to是一个固定搭配的短语，意思是“为了”，后接动词原形构成不定式结构在句子中作目的状语，否定形式是在to前面加not。in order to可以和so as to 互换，但后者不能放在句首。例如：    In order not to be late, you should go now.    为了不迟到，你现在应该走。（2）in order to+动词原形和so as to+动词原形可以转换成in order that+从句和so that+从句。例如：     He did anything in order to make money.    = He did anything in order that he could make money.    为了赚钱，他什么都做。    Please go in quietly so as not to wake the baby.    =Please go in quietly so that we won’t wake the baby.    请不声不响地进去以免弄醒孩子。 3. For one week, she did not do any housework and neither did I. “neither +be动词/助动词/情态动词 + 主语”表示“……也不”，指后者与前者具有相同的情况，但是表示的是否定意义的相同。相当于一个主谓倒装的否定句。neither 此处意为“也不”，是副词。例如：    Mary doesn’t like singing. Neither do I.    玛丽不喜欢唱歌，我也不喜欢。（我和Mary 有相同的情况，前句是否定句，下文用neither开头，主谓倒装）    如果上文是肯定句，下文表示与上文有相同情况时，用“so+ be动词/助动词/情态动词 + 主语”。例如：    Mary likes singing. So do I.    玛丽喜欢唱歌。我也喜欢。（我和Mary有相同情况，前句是肯定句，下文用so开头，主谓倒装） 【拓展】当表示对上文所讲内容的赞同时，可以用“so + 主语 + be动词/助动词/情态动词”或者“neither + 主语 + be动词/助动词/情态动词”来表示。前者用于肯定句，后者用于否定句。例如：    Mary plays the piano well. So she does.    玛丽钢琴弹得很好。她确实弹得好。(表示对上文所讲内容的赞同，前句是肯定句，下文用so开头，主谓不倒装)    Mary doesn’t play the piano well. Neither she does.    玛丽钢琴弹的不好。她确实弹得不好。（表示对上文内容的赞同，前句是否定句，下文用neither开头，主谓不倒装） 4. And she won’t be happy if she sees this mess.（1）本句中if后面的部分是这个句子中的条件状语从句。在以when，after，as soon as等引导的时间状语从句以及以if，unless等引导的条件状语从句中，如果主句是一般将来时，从句则用一般现在时表将来。例如：       I’ll tell her the good news when she comes back.    当她回来的时候，我将把这个好消息告诉她。    If it doesn’t rain, he will come here on time.    如果不下雨，他会按时来这儿的。 常见的“主将从现”有以下三种情况：   1）条件状语从句的主句是一般将来时，那么从句常常用一般现在时。例如：    When I grow up, I’ll be a nurse and look after patients. 我长大后要当一名护士，照顾病人。  2）如果主句是祈使句，那么从句通常要用一般现在时。  例如：    Don’t laugh at me when I make a mistake. 我犯错误的时候不要笑话我。   3）如果主句是含有情态动词的一般现在时，根据需要从句多用一般现在时。例如：You should be quiet when you are in the reading room. 在阅览室时应保持安静。 5. I do not understand why some parents make their kids help with housework and chores at home.本句中的make作使役动词，意为“使……；让……”讲时，常构成make sb. do sth. 意为“使/让某人做某事”，类似的动词还有let，have等。例如：    The boss made them work for long time. 老板让他们长时间工作。    They made us forget past. 他们使我们忘记了过去。    Their boss often let them work long hours every day. 他们老板经常让他们每天工作很长时间。 【拓展】make作使役动词，还可以构成：make + 宾语(sb./sth.) + 形容词/名词（作宾补），即make sb. / sth. + adj./n.。例如：    What he said makes us happy. 他所说的话使我们很高兴。    We made John our monitor. 我们选约翰当班长。 练一练：Ⅰ. 句型转换。A）按要求转换句型。1.
