An ancient Chinese legend says Shen Nong discovered the tea when he was boiling drinking water in the open air. Some leaves from a nearby bush fell into the water and remained there for some time. And a pleasant smell came from the water then. He tasted the mixture and it was wonderful. And in this way, tea was invented. 4. 完成教材3b的任务，要求学生再次阅读短文内容，回答3b中所提出的问题（5分钟）5. 用3c方框中所给的单词的正确形式完成句子；设置一个5分钟的时限；然后请5位同学分别朗读句子，同时核对答案。1. invented 2. drunk 3. produced 4. brought 5. traded环节说明：将听、说、读、写的任务结合起来不仅锻炼了学生的语言综合运用能力，还巩固了学生对目标语言的学习、识记和运用。当堂评价方案（详见当堂训练部分）备课资料包a. 词汇包：1.remain (v.) 保持；剩余；残余remain意为“停留，留下”，相当于stay。“呆在那里”可以说remain / stay there，但“呆在家里”只能说stay (at) home。【备课例句】 She remains in the house all these days. 她这些天一直呆在那栋房子里。They all wished us to remain. 他们都希望我们留下来。【横向辐射】remain作连系动词remain用作连系动词，意为“保持(某种状态)，继续存在，仍旧是”，后面接形容词，名词，分词，不定式或介词短语。【例句】 She remained sitting when they came in他们进来时，她仍然坐着(没有站起来)。Peter became a manager but John remained a worker. 彼得当上了经理,但约翰仍然是一个工人。Whatever great progress you have made, you should remain modest. 无论你取得了多么大的进步,你都应一直保持谦虚。This remains to be proved. 这有待证实。(将来被动动作)Whether it will do us good remains to be seen. 这是否对我们有好处,还要看一看。【课堂变式】The leaves _in the water for a long time. A. came B. remained C. lived D. arrived 【解析】根据for a long time可知是指树叶在水中停留了很长时间，正确答案是B。2. by accident偶然地；意外地【备课例句】He made this mistake by accident.他犯这个错误纯属偶然。【课堂变式】She found her keys _when she cleaned her room after she lost them two weeks ago. A. with mistake B. in this way C. by accident D. with pleasure 【解析】由when she cleaned her room after she lost them two weeks ago可知她是偶然地找到了她丢失的钥匙，正确答案是C。b. 句式包：1. In England, tea didnt appear until around 1660.在英国，茶直到1660年才出现。此句是由until引导的时间状语从句。not. until 意为“只到才”。【备课例句】She didnt leave until I felt better.只到我感觉好点了，她才离开。【横向辐射】until的用法until常用作介词或连词，用来引导介词短语或从句在句子中作时间状语。1. 在肯定句中，until与延续性、持续性动词连用，表示“直到为止”。I worked until late in the afternoon. 我一直干到下午很晚的时候。2. 在否定句中，until常与瞬间动词、短暂性动词连用，表示“直到才”，“不到不”。The rain didnt stop until midnight. 雨直到半夜才停。I wont leave until you promise to help me. 你不答应帮助我，我不会离开。【课堂变式】How was your climbing Mount. Huang?I didnt believe I could do it _I got to the top.A. until while C. after D. and【解析】考查连词用法。notuntil直到才。根据句意“直到我爬到山顶我才相信我能做到”可知选A。
