5、绍17. rather than 而不是18. a circle of good friends 朋友圈子五语法重点Grammar Focus虚拟语气1. 语气就是我们常说的说话人说话的口气:在汉语中，语气是由说话人说话的语调、情节等等表现出来的，动词没有任何变化。而在英语中，除了语调之外，最主要的是动词发生变化而表示不同的语气。在英语中语气分为三类：陈述语气、祈使语气、虚拟语气。2. 虚拟语气：假如我们所说的不是事实，也不是要求、命令、劝告等，而只是一种假设、愿望、建议或是一种实现不了的空想就用虚拟语气。3. 虚拟语气常用在条件句中，及其他一些从句中。    注

6、意：条件句分两种，真实条件句和虚拟条件句。只有在虚拟非真实条件句中，才用虚拟语气，而在真实条件句中，要用陈述语气。    请比较：    1If it is sunny tomorrow , well go to the zoo.     假如明天天气好，我们将会去公园。在这句话中，明天天气好是完全有可能实现的，并非虚拟、梦想，因此是真实条件句。在本句中，适用“主将从现。    2If I were you , I would go at once. 假如我是你的话，我立即就

7、走。在这句话中，条件句，“假如我是你，但事实上，我不可能成为你，这只是假设的情况，没有实现的可能。当条件实现的可能性很小，甚至可以说没有时，就需要用虚拟语气来表示，动词发生了变化。4. 在虚拟语气中，句子动词的时态比真实条件句中的时态后退一步    即：    如今时过去时该用如今时时，用过去时    过去时过去完成时该用过去时时，用过去完成时    将来时过去将来时该用将来时时，用过去将来时    过去将来时过去将来完成时该用过去将来时时，用过

8、去将来完成时    在这一单元中，我们只要求初步接触虚拟语气的用法及构造，学习表示与如今事实相反的情况下如何表达虚拟语气。5. “表示与如今事实相反的情况的虚拟语气    请看例句：If I were you , I would take a small present. 假如我是你的话，我就带上一个小礼物。    注：在这个句子中，即“If I were you 中，一定用were ，而不能用was    这句话中，是与如今的事实相反，“如今假如我是你的话。事实上，我不可能

9、成为你，也就根本没有实现的可能l 请大家注意主句与条件从句中动词时态的变化。从句用过去时主句用过去将来时If 主语主语l 注：虚拟语气中的were 除了在If I were you 的构造中不能改动外，其它情况下有时可用was。l 又如：If I won a million dollars , Id give it to charities. 假如我赢了一百万英镑，我要捐给慈善机构。    在此句中，If条件句中，动词用过去式won，主句那么用should / would 加动词原形。现实情况是我没赢一百万英镑；虚拟的情况是假设我赢了一百万，这种虚拟是不可能变成现

10、实的，因此用虚拟语气。6. 虚拟语气的疑问式，除了动词相应的变化外，其他变化与陈述语气一样    如：    1What would you do if you were in the lions cage ?     假如你在狮子笼里，你会怎么做？    疑问词在句首，主句中助动词提早，从句跟在主句后面。    If I were in the lions cage , Id call for help. 假如我在狮子笼里，我会大呼救命。

11、60;   If I were in the lions cage. Id get out fast. 假如我在狮子笼里，我会迅速出来。    2What would you do if you won the lottery ? 假如你赢了抽奖，你会做什么？    Id give it to medical research.    我会用于医学研究。    Or Id put it in the bank.     我会存到银行。&

12、#160;   Or If I were a millionaire , I would buy a big house in the country.     假如我是百万富翁，我就在乡村买座大房子。    关于虚拟语气，我们要学习的东西还有许多，同学们会在今后的学习当中，渐渐接触到。六Key points 疑难解析1.bring与take      bring的意思是把某人或某物“带来，“拿来，强调方向，即从别处拿到说话人这儿来。    e.

13、g. Next time you come , bring me that book , please.     下次你来的时候，把我的书带来。    take的意思是把人或物“带走，拿走，即从说话人这儿带到别处去。    e.g. Who has taken away todays newspaper ?     谁拿走了今天的报纸？    另外，相似的词还有get 和fetch ，表示到某地找到某人或某物并带回来，强调一去一回。如： 

14、;  Go and get some water. 去弄点水来。   Can you fetch me some paper?     你能给我取点纸吗？2. He might not know anyone at the party.他可能在晚会上谁也不认识。l might 的用法如下：    1是情态动词may的过去式    eg. He said that I might borrow his bike.     他说我

15、可以借他的自行车。    2是may的虚拟语气形式，不表示过去，而表示如今或将来“可以，可能，但语气更委婉、客气，有时表示对可能性有所疑心。如：    a. Might I borrow your bike?  我可能借你的自行车吗？语气比may更委婉    b. He might come today.     今天他可能会来。对“他来的可能性有所疑心3. What if “假如怎么办、“即使又有什么关系？    这是一个固定搭配，引

16、导带条件从句的疑问句。如：What if they dont come?     他们不来怎么办呢？    What if I dont know anyone?     假如我一个人也不认识，怎么办呢？4. I get nervous before big parties.    在大的晚会之前，我会感到紧张。    get nervous 变得紧张，get是系动词，nervous 是形容词做表语。    又如：b

17、e nervous 或feel nervous 均可表达同样的含义。5. in public 公共的、公开的    eg. Lily is very shy , and she is afraid to speak in public.     莉莉很害羞，她害怕在公众场合讲话。6. ask ones permission 征求某人的同意。    without permission 没有得到答应。7. introduce vt. 介绍    introduce sb to

19、me and read a good book than go to a party.     你可能宁愿呆在家里读书，也不愿去参加晚会。    rather than 宁愿也不注：than与形容词比较级无关    rather , than 既可分开用，也可合在一起用，译成“而不是如：    1rather die than surrender 宁死不屈    2I , rather than you , should do the work.
