二 小组探究(二)汉泽英
三 精讲点拨典型例题解析:
1.--What a nice classroom! --It ____ every day.
A. is cleaning B. has cleaned C. must clean D. is cleaned
解析:推测这句话的意思应该是“它每天都被打扫”,考查被动语态的结构be + 动词的过去分词。因此答案应该选D。
2.I know Beijing well. I ____ there three times.
A .will go B. have been C. went D. have gone
解析:推测这句话的意思“我很了解北京,我去过那三次”。表示去过应该采用的时态是现在完成时,因此可排除A和C,区别have been和have gone,have been 去过;have gone 去了(还没回来)。因此应该选择B。
1.--Look at the sign on the right. --Oh, smoking ____ here.
A .doesn’t allow B. isn’t allowed C. didn’t allow D. wasn’t allowed
2. --Will you come to the dinner party? --I won’t come unless Jim ______.
A. can’t be invited B. was invited C. will be invited D.is invited

错误地 偶然地 根据
1)教学 操练1a, 1c, 2c学生看书本上1a ,1b 完成1a,1b 2)教学2a, 2b ,听一听 填一填 完成2a and 2b. 3)2a,2b 回答问题1. What is this article about? 2. Was it invented on purpose or by accident? 3. When was it invented? 4. Who was invented by? 二.精讲点拨:
1. Potato chips were invented by mistakes. mistake 作名词 “错误” make a mistake 出错e.g. You have made a mistake here. mistake…for… 错把……当作…… They mistook him for his brother. by mistake 错误地 e.g. They sent the letter to me by mistake. 2. Geroge wanted to make the customer happy. make表示“使……怎么样”,其后常带复合宾语。常见结构为:主语+make+宾语+名词/形容词(做宾补) water (产生) a p smell . 典型例题解析:1. Did you know that tea…was invented by accident? by accident “偶然地,碰巧”。同义词组 是by chance,同义词是accidentally, 反义 词组是on purpose. e.g. he found a new way to solve the problem by accident. 2. Although tea wasn’t brought to the western world until 1610, …(1) although 作连词, 意为 “虽然,尽管”,引导让步状语从句, 我们不能根据汉语习惯, 在后面使用连词but, 不过它可以与yet, still连用;若主从句的主语相同, 且从句谓语含有动词be, 可将从句主语和动词be省略。e.g. Although he is very busy, he always talks with us. (2) not…until 意为 “直到……才”until 引导一个时间状语从句。 I did not go to bed until I finished my homework. 3. According to an ancient Chinese legend, the emperor Shen Nong discovered tea…(1) according to 是个短语介词,意为 “根据……;依照……”后接代词,名词或由疑问词以及whether引出的名词性从句。e.g. According to the radio, it will rain tomorrow. (2)discover意为“发现”,指发现的对象是 本来存在的。 find意为“找到”,强调结果。 invent意为“发明”,发明的对象是以前没 有的东西。3. Some leaves from a nearby bush fell into the water and remained there for some time. (1) nearby adj. “附近的“,e.g. He works in a nearby factory. (2)leaf 的复数形式为leaves (3)remain 表示 “继续留在某处” e.g. How long will you remain here? (4) fall into “落入, 陷入”e.g. He was drunk and fell into the water.
