一. 教学内容： chapter four: language and speaking 二. 重点、难点1. 祈使句（imperative sentence）定义：祈使句是用来表达命令、请求、劝告、警告、禁止的句子。祈使句最常用于表达请求、命令。（1）祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为动词原形，句末则使用句号来表示结束。如：go and wash your hands. 去洗你的手。（表命令）be quiet, please. (please be quiet.) 请安静。（表请求）（2）肯定结构：①do型（即：动词原形+宾语+其他成分）。如：please have a seat here. 请这边坐。有的祈使句在意思明确的情况下，动词可以省略。如：this way, please. = go this way, please. 请这边走。②be型 （即：be+表语+其他成分）。如：be a good boy! 要做一个好孩子!③let型（即：let+宾语+动词原形+其他成分）。如：let me help you. 让我来帮你。（3）否定结构：① do 型和be型的否定式都在句首加don’t构成。如：don’t forget me! 不要忘记我！don’t be late for school! 上学不要迟到！② let型的否定式有两种： “don’t＋let+宾语+动词原形+其他成分”和“let+宾语+not+动词原形+其他成分”如：don’t let him go. / let him not go.别让他走。③有些祈使句可用no开头，用来表示禁止。如：no smoking! 禁止吸烟！no fishing! 禁止钓鱼！（4）“let”开头的祈使句由“let”开头的祈使句是个常见的动词句型，它的主要用法有下列三种：①表示“建议”。在此句型里，let后面要跟第一人称的代词宾格形式。如：let me try.该句型语气委婉，比don’t开头的祈使句客气。试比较：don’t disturb him. let’s not disturb him.②表示“间接命令”或“愿望”。在此句型中，let后面要跟第三人称代词宾格形式或名词。如：just let her try! 就让她试试吧！let each man decide for himself. 让每个人自己决定吧！（5）使用“let”的祈使句时，必须注意以下几点：①“let”的否定式有两种形式：“don’t let …”和 “let … not”。如果宾语是第三人称用“don’t let …”；如果宾语是第一人称，则用“let…not”。 如：don’t let this type of things happen again.it’s raining now. let’s not go out until after the rain.②“let”适用于现在时态，可以有被动语态。如：let the recalcitrant criminals be sent to prison.let all the dedicated capable staff be promoted. ③“let”后面跟不带“to”的不定式，还可以是某些副词：out，in，down，alone等。 如：let the puppy out.open the windows and let the fresh air in.the room is too sunny. let the blinds down.let me alone, please.④用“let’s”时把谈话者的对象包括在内；用“let us”时，并不包括对方。如：1. let’s try it, shall we?let us do it by ourselves, will you?2. david, pay attention. 大卫，请注意。pay attention to 注意……pay attention to your pronunciation. 请注意你的发音。 数词概述：数词是表示数目多少或顺序先后的词。数词的种类： 基数词和序数词。1. 基数词的构成1-12 单独记： one, two, three , four, five, six, seven, eight, nine, ten, eleven, twelve13-19词尾为-teen. e.g: thirteen, fourteen, fifteen20, 30, 40逢十词尾为ty, twenty, thirty, forty21-99在十位数和个位数之间加连字符构成。eg: 73 seventy-three , 88 eighty-eight101-999光说几百，再加and，再加末尾两位数。eg: 178 one hundred and seventy-eight238 two hundred and thirty-eight1000 以上的数词，先从后向前数， 每三位用一逗号隔开 第一个逗号表示thousand（千）， 第二逗号表示million(百万)， 第三个逗号表示billion(十亿)，然后一节一节用几百几十几的方法。eg: 1004 one thousand and four147258 one hundred and forty-seven thousand , two hundred and fifty-eight18657421 eighteen million, six hundred and fifty-seven thousand , four hundred and twenty-one 注意：在这类数词中hundred, thousand, million, billion等词一般都用单数形式。2. 序数词的记忆口诀：一，二，三要单独记，one-first, two-second, three-thirdth 要从四加起, fourth, sixth,eight , 少个t, eighthnine 去掉e, nine-ninthv 要用f来代替five-fifth, twelve-twelfthty就成tie, twenty-twentieth若问“几十几”或“几百几”，只变个位记心里，twenty-one—twenty-first 重点句子：1. please have a seat.请坐。sit (v.) 动词， 意思是坐，seat（n.）意思是座位。2. pay attention 注意3. add 3 and 9 ( 3 +9)4. subtract 3 from 9 (9-3)5. multiply 3 by 9 ( 3 ×9)6. divide 9 by 3 ( 9÷3)7. 3 plus 9 equals/is 12 ( 3+9=12)8. 9 minus 3 equals/ is 6 (9-3=6)9. 3 multiplied by 9 equals/is 27( 3×9=27)10. 9 divided by 3 equals /is 3( 9÷3=3)重点习题：1. this is a meeting of the world’s most ______ ( power, powerful) countries.2. i played tennis five ______ ( times, time) last week.3. the ______ ( alive , living) things can’t live without air or water.4. the chinese ______ ( invented, invention ) the compass.5. 13 is an ______ ( odd, even) number.6. he was ______ ( amusing, amused) to hear the news.7. ______ higher, and you will see the house. a if you stand b. to stand c. when you stand d. stand8. ______ forget to wire to me when you _____ get there next tuesday. a. don’t, will b. please, will c. please,/ d. don’t,/9. could you tell me _____ to do next? nothing more. let’s have a rest.a. why b. when c. what d. how10. tell the boys _____ in the classroom.a. don’t make a noise b. not to make noisec. not to make a noise d. not make a noise11. let’s ______ our time.a. not waste b. no wasting c. not to waste d. no waste12. _______ rude to your classmates.a. don’t be b. isn’t c. be not d. aren’t13. how many people are there? about _______.a. five hundred b. five hundreds c. hundreds d. hundreds of14. usually children have ______ holiday in summer.a. an 8-week b. a 8-week c. an 8-weeks d. a 8-weeks15. this room is ______ than that one. a. two time bigger more b. twice biggerc. two time bigger d. two times more bigger16. when were you born? i was born ______.a. in oct.8,1990 b. in 1990, oct.8c. on oct.8, 1990 d. on 1990, oct.8
