Important and Difficult Points: Make sure the students master the grammatical items. Knowledge Links: Teach students to remember the grammatical rules. Learning Guidance: Refer to the text book and cooperate with partners Learning Process:
一、but用作并列连词 作为并列连词,表转折，语气最强, but 可以连接两个并列的分句或者两个并列的成份,译为“但 是”,“可是”。能表示下列意义: 1、表示意义转折。例如: I was going to write, but I lost your address. 2、表示对比或对照,通常与否定词连用。例如: He is not good at maths, but he is good at English He scarcely knows French, but he speaks English perfectly. 3、出现在句首或句与句之间,表示异议,惊奇或吃惊。如: A:I have won the long jump. B: But that's wonderful! But that question doesn’t arise. 但没发生那个问题。 4、用在表示歉意的词语之后,引起一个句子,常不能译为“但是”,可以不译出。如: I'm sorry, but I can't come. Excuse me, but can you tell me the way to the library? 【注意】不要按汉语意思将“虽然…但是…”直译为although…but… but 不可与although/ though 连用。 误：Although we are poor, but we are happy. (去掉Although或but中任一个) 巩固练习: ( A 级) 1. Stand over there _____ you’ll be able to see it better. A.or B. while C. but D. and 2. —I think George doesn’t really care for TV plays. —Right, _____ he still watches the program. A. and B. but C. or D. so
二however作为连词和副词的用法。 作为连词时，其引导的从句可放在主句前，也可放在主句后，表示“不管…”。 However I cooked eggs, she still refused to eat them. 不管我用什么方法做鸡蛋，她仍不肯吃。 ▁▂▃▄▅▆▇█▉▊▋▌精诚凝聚 =^_^= 成就梦想 ▁▂▃▄▅▆▇█▉▊▋▌ ▃ ▄ ▅ ▆ ▇ █ █ ■ ▓点亮心灯 ~~~///(^v^)\\\~~~ 照亮人生 ▃ ▄ ▅ ▆ ▇ █ █ ■ ▓ However 用作副词时，表示转折，其意为“可是”“然而”等。可放在句首、句中或句末，但必须用 逗号与主句隔开。 如：My father, however, did not agree. 但是，我父亲不同意。 My room is small; however, it’s comfortable. 我的房间很小，但却很舒服。 He said that it was so; he was mistaken, however. 他说情况如此，可是他错了 【注意】：however当副词讲时，不能像 but 那样直接连接两个句子，注意正句中的标点符号。 如：我们都已尽了最大的努力，不过我们还是输了。 误：We all tried our best, however we lost the game. 正：We all tried our best, but we lost the game. 正：We all tried our best; however, we lost the game. 正：We all tried our best. However, we lost the game. 三．连词while 的用法。 While 可作从属连词，意思是“虽然”，此时可与although互换。 例如: While I haven’t seen his, I have regarded his as my friend. 虽然我没有见过他，我一直把他当作我的朋友。 While 可作并列连词，表然而，强调前后之间的对比，所引导的句子一般不位于句首。 例如: He likes pop music, while I like classical music 他喜欢流行音乐，然而我喜欢古典音乐。 四．表示转折的从属连词有although, though, even if , even though, while, as, no matter (how,/what/ when…)= however/ whatever/whenever Although she lacks experience, ( yet /still ) she is ready to do the job. He won’t let out the secret even if /though he knows it. While we don’t agree on the matter, we continue to be friends. Don’t trust him, no matter what he says. Child as/though he is, he knows a lot.
【拓展】: although意为“虽然，尽管”，较正式，通常放在句首，而though 多用于非正式文As 表示虽然引导让步状语从句时，要把从句中的表语，状语甚至动词原形放到句首，当把名词放在as前时，名词前不加冠词。另外，though引导的从句，即可用正常语序，也可同as一样，即把表语，状语甚至谓语动词等放到句首。Although 不可以倒装。 ▁▂▃▄▅▆▇█▉▊▋▌精诚凝聚 =^_^= 成就梦想 ▁▂▃▄▅▆▇█▉▊▋▌
