    1、學(xué)生觀察1a中的圖片相互提問:A:what can you see in picture 1?
    B: I can see……. A:What are they doing? B: They are …….(學(xué)生通過相互提問熟悉圖畫內(nèi)容,為聽力做準備。)
    2、教師讓學(xué)生歸納1a-2c中所出現(xiàn)的反意疑問句,讓學(xué)生觀察、總結(jié)反意疑問句的構(gòu)成。知識剖析: 反意疑問句要點簡述
    反意疑問句又叫附加疑問句,是在陳述句后,對陳述句所敘述的事實提出的疑問。
    其基本結(jié)構(gòu)有兩種:一是“肯定陳述句+簡略否定問句”;
    二是“否定陳述句+簡略肯定問句”。
    反意疑問句的前后兩部分在時態(tài)、人稱和數(shù)上都要保持一致。
    如:It looks like rain, doesn’t it?
     He doesn’t need to work so late, does he?
    幾種特殊情況:
     1. 陳述部分是there be 句型,疑問部分也用 there be 句型。
    There is a book on the desk, isn’t there?
     2. 陳述部分如有 nothing, nobody, never, few, little, hardly 等否定詞時(不包括加否定前綴變來的,如:dislike, unhappy等),疑問部分用肯定形式。
     They have never been to the farm, have they?
    There is little water in the glass, is there?
    He dislikes history, doesn’t he?
     3. 陳述部分為祈使句時,反義部分用 will you , won’t you 。以Let’s開頭的祈使句,疑問部分用 shall we .
     Go to the cinema now, will you?
     Let’s have a party, shall we?
     4. 陳述部分含賓語從句時,疑問部分一般反問主句,但主句含有 I/We think/believe/suppose … 時, 疑問部分要反問從句(要注意否定轉(zhuǎn)移情況)。
    He knew that the woman was a thief, didn’t he ?
    I don’t think he is a good student, is he?

    自主互助學(xué)習(xí)
    學(xué)生觀察3a中的圖片相互討論并預(yù)測3a答案
    知識剖析:學(xué)習(xí)反意疑問句,特別要注意的問題
    1.陳述句如果是there be結(jié)構(gòu)時,疑問句部分仍用there。如:
    There once was a man named Saint Nicholas, wasn’t there?
    2. 在英語口語中,“I am +表語結(jié)構(gòu)”,后面的反意疑問句多用aren’t I 來體現(xiàn)。
    如: I am very interested in learning English, aren’t I?
     3. 陳述句的主語是動詞不定式,動詞的-ing形式或從句,疑問部分的主語多用it來體現(xiàn)。如:Taking care of our environment is very important, isn’t it?
    What he said it is right, isn’t it?
    4. 陳述句中含有not, no, hardly, neither, never, few, little, too …to等否定詞或具有否定意義的詞時,疑問部分常用肯定形式。如:
    Few people knew the news, did they?
    Tom has never been to England, has he? 但陳述句中如果帶有否定意義的前綴和后綴的單詞時,整個句子仍視為肯定句,反意疑問部分多用否定形式。
    如:She is unhappy, isn’t she?
    5. 陳述句的主語是nobody, no one, everyone, somebody等不定代詞時,反意疑問部分的主語多用they(當(dāng)強調(diào)全體時)或he(當(dāng)強調(diào)個體時)。如果陳述句的主語是something, nothing, anything, everything等不定代詞時,反意疑問部分的主語多用it。
    如:No one knows him, do they?
    Someone is waiting for you, isn’t he?
    Nobody says a word about the accident, do they?
     Everything seems all right, doesn’t it?
    6. 陳述句是主從復(fù)合句時,如果主句的謂語動詞是think, believe, expect, feel, guess等詞,且主語是第一人稱I時,反意疑問部分的人稱、時態(tài)與賓語從句保持一致,同時還要考慮到否定的轉(zhuǎn)移。如:
    I believe that the boy can get a ticket for you, can’t he?

    知識剖析:重點、難點句子
    1.P 79 1a How much did that shirt cost? 那件襯衣多少錢?
    句中cost作動詞,意為“花費”,與pay, take, spend同義,但用法不同,其句型為“某物+cost +人+時間/金錢”。試比較下列句子:
     The book cost me five dollars. 這本書花了我5美元。
    It took me five dollars to buy the book. 買這本書花了我5美元。
    I spent five dollars on the book. 我花5美元買這本書。
    注意:四個表示“花費”的動詞,其句式各不相同,小結(jié)為:
    (1)sth. cost sb. money某物花某人金錢
    (2)It takes sb. money to do sth. 花某人金錢做某事
    (3)sb. pay money for sth. 某人為某物花金錢
