一、教法建议
【抛砖引玉】
本单元围绕实验这一题材，通过介绍实验室的注意事项，有助于学生养成良好的习惯，并使学生掌握提出要求的方式；循循善诱的化学教师、令人深思的化学课，更会有利于培养学生认真观察、一丝不苟的严谨的治学精神；注意定语从句在日常教学中的感性知识的渗透，为今后的系统学习做好准备。
【指点迷津】

二、学海导航
【学法指要】
⒈ _____ you begin to do something, you must do it well. That's the way.
A. Because B. Imagine C. Suppose D. Once
【解答】答案是D。该题为条件状语从句。once除作副词外，还可作连词，意为“一旦……就”，相当于if；但if侧重考虑条件是否具备，once则强调从句动作所涉及的结果，不存在条件是否具备问题。
⒉You'll fail in the examination ______ you work hard at your lessons.
A. if B. unless C. as D. since
【解答】答案是B。本题测试逻辑思维。四个选项都是连词，unless相当于if not。句意：如果你不努力学习功课，考试就不能及格。A、C、D选项不合逻辑，故应排除。
⒊The light is on. Don't forget to ______ when you leave.
A. turn off B. turn off it C. turn it off D. close it
【解答】答案是C。英语短语动词有三种，其结构分别是：
(1)vt. +adv. (2)vi. +prep. (3)vi. +adv.前两种是及物动作，第三种为不及物动作（例如get up）。第一种的宾语如果是名词，置于adv.前后均可；如为代词，则必须置于adv.之前。第二种的宾语，不论是名词还是代词，必须置于介词之后。turn off中的off是副词，因此选C。
⒋He tasted the medicine and found it _____ .
A. tasted bad B. was tasted badly C. tasted badly D. tasted well
【解答】答案是A。taste用作动词时，既可作及物动词，又可作系动词。题干上的taste是及物动词，意为“品尝”；选项中的taste是系动词，意为“尝起来……”，后接形容词、介词短语作表语。bad是形容词，据此排除其它选项。
⒌Last night he stayed at home _____ to the movie.
A. instead go B. instead of go
C. instead goint D. instead of goine
【解答】答案是D。instead of是短语介词，可接名词、介词短语、形容词、副词等。注意instead of前后谈及的两件客体在意义结构上必须是平行关系。例如：
①He got excited instead of angry.
②He went to Shanghai instead of back to Beijing.
③He walked more slowly instead of faster.
【妙文赏析】
Perhaps the most unforgettable person I have ever met is my teacher Mr.Smith. He taught us history. I still remember his lively way of teaching. Because he explained everything clearly and to the point, his classroom was always full of students. He expressed his ideas in a lively and interesting way, introduced many helpful things to his teaching, such as painting, recording and maps. He even sang a song in class to deepen his points. If it is true that life makes a wise man smile and a foolish man cry, Mr Smith is of course a wise man.
【思维体操】
短文改错：
此题要求你对一篇文章改错。先对每一行做出判断是对还是错。如果是对的，在该行右边横线上划一个勾（√）；如果有错误（每行不会多于一个错误），则按情况改错如下：
此行多一个词：把多余的词用斜线（\）划掉，在该行右边横线上写出该词，并也用斜线划掉。
此行缺一个词：在缺词处加一个漏字符号（ ），在该行右边横线上写出该加的词。
此行错一个词：在错的词下划一横线，在该行右边横线上写出改正后的词。
注意：原行没有错的请不要改。

2. ________
3．________
4．________
5．________
6．________
7．________
8．________
9．________
10. _______
【解答】
⒈away改为out. "break out"意为"突然爆发、发生".
⒉ 正确
⒊in改为of."warn sb. of sth."意为"提醒或警告某人注意某事".
⒋other改为others. others为代词，意为“其余的人或事”。
⒌take改为taking. "it is no good doing sth."意为"做某事没有用".
⒍staying改为stay. Stay out为祈使句。
⒎ 去掉in
⒏ 去掉on. call sb./sth.表示“给某人打电话”，而call on意为“拜访”、“号召”。
⒐Always改为Never，因为根据句意应为“不要自己去救火”。
⒑that改为which，引导一个非限制性定语从句。注意关系代词that不能用于非限制性定语从句中。
三、智能显示
【心中有数】
在近些年的英语高考中，本单元要求掌握的连词as, while, unless及半系动词taste等都是比较重要的内容及考查热点。其中as表示时间，注意和when, while的区别，表示原因，注意和because, since, for的区别；while在本单元中表示转折，相当于but，强调前后的对比。
【动脑动手】
单项填空 从A、B、C、D四个选项中，选出可以填入空白处的最佳答案。
⒈ ______ the day went on, the weather got worse.
A. With B. Since C. While D. As

6._______ , I must say I'm pleased to see so many friends here.
A. First of all B. Not at all
C. After all D. At all
【解答】
⒈ 答案是D。此处连词as引导时间状语从句，表示“随着……”。
⒉ 答案是A。该句中的as相当于when；during虽可表示时间，但它是介词，不能接句子。句意是“母亲焦急是因为小爱丽斯病了，尤其是当时父亲还在法国。”
⒊ 答案是D。并列连词while含有对照之意。句意是：“她以为我在谈论她女儿，而实际上我是在谈论我的女儿。”
⒋ 答案是B。unless引导一个条件状语从句。
⒌ 答案是C。第一个taste是及物动词，意为“品尝”；后一个taste是系动词，意为“尝起来……”，后接形容词good作表语。
⒍ 答案是A。first of all意为“首先”。全句的意思是：“首先我要说，我很高兴在这里见到这么多朋友。”
