一、教法建議
【拋磚引玉】
本單元圍繞實驗這一題材，通過介紹實驗室的注意事項，有助于學生養成良好的習慣，并使學生掌握提出要求的方式；循循善誘的化學教師、令人深思的化學課，更會有利于培養學生認真觀察、一絲不茍的嚴謹的治學精神；注意定語從句在日常教學中的感性知識的滲透，為今后的系統學習做好準備。
【指點迷津】

(3) once (4) unless

二、學海導航
【學法指要】
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。該題為條件狀語從句。once除作副詞外，還可作連詞，意為“一旦……就”，相當于if；但if側重考慮條件是否具備，once則強調從句動作所涉及的結果，不存在條件是否具備問題。
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。本題測試邏輯思維。四個選項都是連詞，unless相當于if not。句意：如果你不努力學習功課，考試就不能及格。A、C、D選項不合邏輯，故應排除。
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。英語短語動詞有三種，其結構分別是：
(1)vt. +adv. (2)vi. +prep. (3)vi. +adv.前兩種是及物動作，第三種為不及物動作（例如get up）。第一種的賓語如果是名詞，置于adv.前后均可；如為代詞，則必須置于adv.之前。第二種的賓語，不論是名詞還是代詞，必須置于介詞之后。turn off中的off是副詞，因此選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用作動詞時，既可作及物動詞，又可作系動詞。題干上的taste是及物動詞，意為“品嘗”；選項中的taste是系動詞，意為“嘗起來……”，后接形容詞、介詞短語作表語。bad是形容詞，據此排除其它選項。
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是短語介詞，可接名詞、介詞短語、形容詞、副詞等。注意instead of前后談及的兩件客體在意義結構上必須是平行關系。例如：
①He got excited instead of angry.
②He went to Shanghai instead of back to Beijing.
③He walked more slowly instead of faster.
【妙文賞析】
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.
【思維體操】

此行多一個詞：把多余的詞用斜線（\）劃掉，在該行右邊橫線上寫出該詞，并也用斜線劃掉。
此行缺一個詞：在缺詞處加一個漏字符號（ ），在該行右邊橫線上寫出該加的詞。
此行錯一個詞：在錯的詞下劃一橫線，在該行右邊橫線上寫出改正后的詞。
注意：原行沒有錯的請不要改。

3．________
4．________
5．________

7．________
8．________
9．________
10. _______
【解答】
⒈away改為out. "break out"意為"突然爆發、發生".
⒉ 正確
⒊in改為of."warn sb. of sth."意為"提醒或警告某人注意某事".
⒋other改為others. others為代詞，意為“其余的人或事”。
⒌take改為taking. "it is no good doing sth."意為"做某事沒有用".
⒍staying改為stay. Stay out為祈使句。
⒎ 去掉in
⒏ 去掉on. call sb./sth.表示“給某人打電話”，而call on意為“拜訪”、“號召”。
⒐Always改為Never，因為根據句意應為“不要自己去救火”。
⒑that改為which，引導一個非限制性定語從句。注意關系代詞that不能用于非限制性定語從句中。
三、智能顯示
【心中有數】
在近些年的英語高考中，本單元要求掌握的連詞as, while, unless及半系動詞taste等都是比較重要的內容及考查熱點。其中as表示時間，注意和when, while的區別，表示原因，注意和because, since, for的區別；while在本單元中表示轉折，相當于but，強調前后的對比。
【動腦動手】

C. After all D. At all
【解答】
⒈ 答案是D。此處連詞as引導時間狀語從句，表示“隨著……”。
⒉ 答案是A。該句中的as相當于when；during雖可表示時間，但它是介詞，不能接句子。句意是“母親焦急是因為小愛麗斯病了，尤其是當時父親還在法國�！�
⒊ 答案是D。并列連詞while含有對照之意。句意是：“她以為我在談論她女兒，而實際上我是在談論我的女兒�！�
⒋ 答案是B。unless引導一個條件狀語從句。
⒌ 答案是C。第一個taste是及物動詞，意為“品嘗”；后一個taste是系動詞，意為“嘗起來……”，后接形容詞good作表語。
⒍ 答案是A。first of all意為“首先”。全句的意思是：“首先我要說，我很高興在這里見到這么多朋友。”
