She went to work, however, and tried to concentrate. Alice is a good student．However, she has one shortcoming． The composition is all right. There is room for improvement, however. 1. “但是，可是”（相当于 yet; however;）； e.g. She cut her knee badly, but didn't cry. I'd love to go to the theatre tonight, but I'm too busy. He was tired but happy after the long walk. 2. 用于表示歉意的话语之后，表示谢绝或不赞成； e.g. Excuse me, but could you tell me where the post office is? I’m sorry, but I have another appointment tonight. 3. “而; 却”（相当于 on the contrary 相反地）； e. g. You've bought the wrong shirt. It's not the red one I wanted but the blue one. Tom went to the party, but his brother didn't. 4. 含“but”的习惯搭配: ① “not... but...”意为“不是...而是...”，连接两个并列的名词、形容词、副词、短语或分 句等； Bamboo is not a tree, but a kind of grass. He failed not because he isn't clever but because he didn't work hard. ② have no choice but to do ... 除了...，别无选择 / do/does/did nothing but do... 除了...， 别无他事可做 ③ not only ...but also ...意为“不但...而且...；既...又...”，连接两个并列成分 【考例】 --- Would you like to come to dinner tonight? --- I'd like to, ___ I'm too busy. A. and B. so C. as D. but [答案]D。but 与前面形成转折，符合语意。而表并列的 and， 结果的 so，原因的 as 都不符 合句意。 【考例】---Would you like to come to my house for dinner tonight? ---I'd love to， I have lots of work to do． A. so B or C. and D．but [答案]D。[解析]考查转折连词。so(表结果)，or(表选择)，ad(表并列)，but(表转折)，根据句 意：“我很乐意去， 但我还有一些事要做”可推断选 but，表转折。 【考例】It was very cold and windy, _________ those farmers were working hard on the farm. A. and B. or C. but D. so [答案]C。[解析]考查连词的用法。 but 表转折，and 表并列，or 表选择，so 表顺接。根据句 意选 C。 and 的用法： 用来连接语法上同类的词、短语或句子。 1. “和”、“又”、“并且”（相当于 also; in addition to）； e. g. bread and butter 面包和黄油 slowly and carefully 缓慢而仔 细地 Tidy up your room. And don't forget to make your bed! She came in and sat down. 她进来以后就坐下了。 【注意】：并列结构中，and 用于肯定句，通常否定句用 or。 e. g. There is no air or water in the moon. He can't read or write. 2. “加”（相当于 plus），连接两个数字,谓语动词用单数。 e. g. 5 and 5 makes 10. 5 加 5 等于 10。 3. 用在祈使句后，表示结果，意为“那么, 就” 。 e. g. Work hard and you will succeed. 努力干吧，你会成功的。 4. 常见搭配： e. g. go and fetch 去拿 come and look at 来看看 wait and see 等着瞧吧 and so on 等等 try and improve. 尽量改进 two thousand, two hundred and sixty four 二千二百六十四 【考例】---I don't like chicken ___ fish. ---I don't like chicken, ___ I like fish very much. A. and； and B. and； but C. or； but D. or；and [答案] C。否定句中表并列用 or, but 表转折。 【考例】Study hard, ________ you'll pass the exam. A. or B. and C. but D. so [答案] B。[解析] 考查并列连词。or 表示选择，and 表示并列，but 表示转折。 从属连词： 连接两个或两个以上的分句。 表原因的从属连词: because “因为” because 的用法： 1. 表示的是必然的因果关系，语气较强，通常放在主句之后，若需强调则放在主句之前。 e. g. I did so because I was happy. 2. 通常用来回答 why 提出的问题。 --Why do you look so sad? --Because I have lost my wallet. 3. 在英语里不能将 so 与 because 连用! e. g. 因为下雨，所以我们呆在家里。 正：Because it was raining, we stayed at home. 正：It was raining, so we stayed at home. 误：Because it was raining, so we stayed at home. 4. because of, 意为“因为”, 是复合介词，其后可接名词或名词性短语等。 e. g. He couldn’t come because of illness. 他因病不能来。 He couldn’t come because he was ill. 【注意】：because of 不能直接引导从句或后接 that 引导的从句。 【考点拓展】since（从属连词，“既然，由于”），as（从属连词，“因为，由于”）； 【考例】I have been trying my best to study English ________I want to have a chance to be a volunteer for the Beijing Olympics. A. until B. because C. though D. when [答案] B。[解析] 本题考查连词的用法。until 表示“直到……才”常用来引导时间状语从句； because"因为”用来引导原因状语从句，而 though"尽管”用来引导让步状语从句。根据主从句 的前后关系判断，应该选用表示原因的 B 项。 【考例】Ricky caught a "bad cold yesterday, ________ he had to stay at home. A. because B. but C. or D. so [答案] D。 because 因为，引导句子；because of 因为引导短语 But 但是，（表示转折＝ however，＝whereas），不能够和 though/although 连用对不起，除了（＝except）Or 和（ and 的否定形式），或者，否则（通常是将来时态，表示结果）So 所以，表示结果，不能够和 because 连用；如此引导形容词/副词。句意为： Ricky 昨天得了重感冒，所以他不得不呆在 家里。 表让步的从属连词： although 虽然，尽管 though  although/though 的用法： 1. 在一般情况下二者可以互换使用，都可与 yet, still 连用，但不能与 but 连用。 e. g. Although he is poor, he’s still happy. 虽然他很穷，他仍然很快乐。 I will try it, though I may fail. 即使我可能失败, 我也要试一下。 【注意】： ① although 引导的让步状语从句位于主句之前的情况较多，though 引导的让步状语从句可 位于主句之前或主句之后。 ② though 可用于句尾: We all tried our best. We lost the game, though. 我们都已尽了最大的力量. 不过我们还是输 了. 巩固提升： 一、单选题 1．Keep an English diary, ______your English will improve.
