点拨 本句中使用了插入语do you think。插入语经常插到一个语法结构完整的句子里去，对句子的内容作一些附加说明，有时表示说话者的态度和看法等，它不和句子的成分发生结构上的关联，常置于句首、句中或句末。把插入语去掉之后，句子的结构和语义还是完整的。 拓展常用于插入语的动词有suppose, know, hope, believe, guess, find, say等。如：you came by air, i suppose.用作插入语的主要有：副词、形容词、介词短语、不定式、动词-ing形式短语和分句。如：two middle-aged passengers fell into the sea. unfortunately, neither of them could swim.if she ran towards it, it might attack her. worse still, it could even carry off the baby in its mouth.your performance in the driving test didnt reach the required standard in other words, you failed.to be frank with you, i have no money on me. judging from what he said to me today, his minds made up.it is so nice to hear from her. believe it or not, we last met more than thirty years ago.仿写 _ _ (令我惊讶的是, 他说的话和所做的事没有任何关系。)6. although he is one of chinas most famous scientists, yuan longping considers himself a farmer, for he works the land to do his research. 分析 这是一个含让步状语从句的主从复合句。结构为: 让步状语从句(although he is one of chinas most famous scientists)+主句(yuan longping considers himself a farmer)。 主句中包含“consider + 宾语 + n.”结构。 for引导的从句并不表示原因, 而只是为主句中所说的话提供推断的理由, 加以解释, 此时for前要加逗号。 e.g. the shop was quite new, for it had opened only the week before. work vi./ vt. 经营, 管理 work the land = grow crops on it耕耘土地 e.g. he works a big farm. 他经营着一个大的农场。7. in 1974, he became the first agricultural pioneer in the world to grow rice that has a high output.the first . to do sth. 第一个做。动词不定式(to grow rice) 作定语, 修饰the first agricultural pioneer。the first, the last, the second, the only等短语后多用动词不定式作后置定语。8. this special strain of rice makes it possible to produce one-third more of the crop in the same fields. make it +宾语补足语+动词不定式, it做形式宾语, 动词不定式是真正的宾语。 it做形式宾语, 通常和下列动词连用: consider, think, make, find, believe, count, declare, deem, fancy, feel, guess, imagine, judge, prove, see, show, suppose, understand, take等。9. using his hybrid rice, farmers are producing harvests twice as large as before. 英语中的倍数表达法共有三种形式: 1) 倍数 + 形容词/副词的比较级 + than. 2) 倍数 + as +形容词/副词的原级 + as. 3) 倍数 + the + 名词+ of. e.g. this building is five times higher than that one.这座楼比那座楼高出五倍。 this building is five times as high as that one.这座楼是那座楼的五倍高。 this building is five times the height of that one. 这座楼是那座楼的五倍高。the new building is four times the size of the old one.the new stadium being built for the next asian games will be _ the present one. a. as three times big as b. three times as big asc. as big as three times d. as big three times as【点拨】正在建的下一届亚运会的新体育馆是现在体育馆的三倍大。倍数的表达：倍数+ as + 形容词的原级+ as .。10. he enjoys listening to violin music, playing mah-jong, swimming and reading. 动词-ing形式作宾语。 考例 after he became conscious, he remembered _ and _ on the head with a rod. a. to attack; hit b. to be attacked; to be hit c. attacking; be hit d. having been attacked; hit 点拨 remember doing sth.“记着做了某事”(事已完成)；且he和attack与hit之间是动宾关系，故用被动语态。remember to do sth. “记得要做某事”(此事未做)。 讨论记录 第二单元注意培养学生的同情心及人道主义精神，学习袁隆平淡泊名利无私奉献的精神。学生在归纳总结时尽量用自己的话语讲述袁隆平的一生。在复习时，从词汇，短语，句子等不同层面归纳本单元所学，要求学
