chapter 4 numbers language【本講教育信息】一. 教學(xué)內(nèi)容： chapter four: language and speaking二. 重點、難點1. 祈使句（imperative sentence）定義：祈使句是用來表達(dá)命令、請求、勸告、警告、禁止的句子。祈使句最常用于表達(dá)請求、命令。（1）祈使句因?qū)ο螅粗髡Z）是第二人稱，所以通常都省略。祈使句的動詞都為動詞原形，句末則使用句號來表示結(jié)束。如：go and wash your hands. 去洗你的手。（表命令）be quiet, please. (please be quiet.) 請安靜。（表請求）（2）肯定結(jié)構(gòu)：do型（即：動詞原形+賓語+其他成分）。如：please have a seat here. 請這邊坐。有的祈使句在意思明確的情況下，動詞可以省略。如：this way, please. = go this way, please. 請這邊走。be型 （即：be+表語+其他成分）。如：be a good boy! 要做一個好孩子!let型（即：let+賓語+動詞原形+其他成分）。如：let me help you. 讓我來幫你。（3）否定結(jié)構(gòu)： do 型和be型的否定式都在句首加dont構(gòu)成。如： dont forget me! 不要忘記我！ dont be late for school! 上學(xué)不要遲到！ let型的否定式有兩種： “dontlet+賓語+動詞原形+其他成分”和“l(fā)et+賓語+not+動詞原形+其他成分”如： dont let him go. / let him not go.別讓他走。有些祈使句可用no開頭，用來表示禁止。如：no smoking! 禁止吸煙！no fishing! 禁止釣魚?。?）“l(fā)et”開頭的祈使句由“l(fā)et”開頭的祈使句是個常見的動詞句型，它的主要用法有下列三種：表示“建議”。在此句型里，let后面要跟第一人稱的代詞賓格形式。如：let me try.該句型語氣委婉，比dont開頭的祈使句客氣。試比較：dont disturb him. lets not disturb him.表示“間接命令”或“愿望”。在此句型中，let后面要跟第三人稱代詞賓格形式或名詞。如：just let her try! 就讓她試試吧！let each man decide for himself. 讓每個人自己決定吧?。?）使用“l(fā)et”的祈使句時，必須注意以下幾點：“l(fā)et”的否定式有兩種形式：“dont let ”和 “l(fā)et not”。 如果賓語是第三人稱用“dont let ”；如果賓語是第一人稱，則用“l(fā)etnot”。 如： dont let this type of things happen again. its raining now. lets not go out until after the rain.“l(fā)et”適用于現(xiàn)在時態(tài)，可以有被動語態(tài)。如： let the recalcitrant criminals be sent to prison. let all the dedicated capable staff be promoted. “l(fā)et”后面跟不帶“to”的不定式，還可以是某些副詞：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.用“l(fā)ets”時把談話者的對象包括在內(nèi)；用“l(fā)et us”時，并不包括對方。如：lets try it, shall we?let us do it by ourselves, will you?2. david, pay attention. 大衛(wèi)，請注意。pay attention to 注意pay attention to your pronunciation. 請注意你的發(fā)音。數(shù)詞概述：數(shù)詞是表示數(shù)目多少或順序先后的詞。數(shù)詞的種類： 基數(shù)詞和序數(shù)詞。1. 基數(shù)詞的構(gòu)成1-12 單獨記： one, two, three , four, five, six, seven, eight, nine, ten, eleven, twelve13-19詞尾為-teen. e.g: thirteen, fourteen, fifteen20, 30, 40逢十詞尾為ty, twenty, thirty, forty21-99在十位數(shù)和個位數(shù)之間加連字符構(gòu)成。eg: 73 seventy-three , 88 eighty-eight101-999光說幾百，再加and，再加末尾兩位數(shù)。eg: 178 one hundred and seventy-eight 238 two hundred and thirty-eight1000 以上的數(shù)詞，先從后向前數(shù)， 每三位用一逗號隔開 第一個逗號表示thousand（千）， 第二逗號表示million(百萬)， 第三個逗號表示billion(十億)，然后一節(jié)一節(jié)用幾百幾十幾的方法。eg: 1004 one thousand and four 147258 one hundred and forty-seven thousand , two hundred and fifty-eight 18657421 eighteen million, six hundred and fifty-seven thousand , four hundred and twenty-one 注意：在這類數(shù)詞中hundred, thousand, million, billion等詞一般都用單數(shù)形式。序數(shù)詞的記憶口訣：一，二，三要單獨記，one-first, two-second, three-thirdth 要從四加起, fourth, sixth,eight , 少個t, eighthnine 去掉e, nine-ninthv 要用f來代替five-fifth, twelve-twelfthty就成tie, twenty-twentieth若問“幾十幾”或“幾百幾”，只變個位記心里，twenty-onetwenty-first重點句子：1. please have a seat.請坐。sit (v.) 動詞， 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 ( 93)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( 39=27) 10. 9 divided by 3 equals /is 3( 93=3)重點習(xí)題：1. this is a meeting of the worlds most _ ( power, powerful) countries.2. i played tennis five _ ( times, time) last week.3. the _ ( alive , living) things cant 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. dont, will b. please, will c. please,/ d. dont,/9. could you tell me _ to do next? nothing more. lets have a rest.a. why b. when c. what d. how10. tell the boys _ in the classroom.a. dont make a noise b. not to make noisec. not to make a noise d. not make a noise11. lets _ our time.a. not waste b. no wasting c. not to waste d. no waste12. _ rude to your classmates. a. dont be b. isnt c. be not d. arent13. 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
