No,it isnt. Its a pen. 不,不是。是鋼筆。 Are these your books? 這些是你的書嗎? Yes,they are. 是的。 (2)一般疑問句 以動詞be,have或助動詞、情態(tài)動詞開頭,以yes或no作回答的問句叫做一般疑問句。回答時可以用完整的句子回答,但大多數(shù)情況下只需作簡略回答。如: Is this your pencil? 這是你的鉛筆嗎? Yes,it is.是的。 Have you any magazines? 你有雜志嗎? Yes,I have.有。EXERCISES 【1】Heres exercise-book. A. a B. an C. two D. 句中的a和an都是不定冠詞,放在單數(shù)可數(shù)名詞前,修飾限定名詞,表示“一個、一塊”的意思。如果名詞的讀音以輔音音素開頭,用不定冠詞a,如:a banana, a pear;如果名詞的讀音以元音音素開頭,要用不定冠詞an,如an orange,an egg。在本句中,book是可數(shù)名詞單數(shù),用冠詞a,而單詞exercise是以元音音素“e”開頭的詞,故要用冠詞an。 【2】根據(jù)上下文,在空格上填上一個恰當?shù)脑~。 (1) you in Class 4? Yes, I . (2)This is a car and that is a car, . (3)Is this a Chinese bike? No. a Japanese bike. (1)本題是以be為謂語的一般疑問句,主語是you,應填Are;答句主語是I,填am。 (2)當前后兩句表述的意思相同,僅主語不同時,在句末逗號后應填上too,表示“這是,那也是”。 (3)Its是It is的縮寫形式,It指代this。由于No后面用的是句號,且后面的句子是一個完整的句子,應看做為一個獨立的句子,故its應大寫第一個字母。 答案 (1)Are; am (2)too (3)Its 【3】從下面各句A、B、C、D中找出一處錯誤并改正。 (1)Thats a Chinese car. A B C D (1)Chinese,Japanese,English等詞均屬專有名詞,書寫時要將第一個字母大寫,應改為Chinese。 (2)That is a pencil box. A B C D (2)英語中有部分單詞是由兩個詞構(gòu)成的,在兩個詞之間須加連字符號“-”,所以應改pencil box為penhcil-box,同學們在學習時要多加注意。 (3)Whats this in English? A B Its computer. C D (3)有些同學在學習時沒有注意漢語和英語表達不同,僅從漢語的角度去理解英語,所以在名詞前面就缺少了冠詞,應在computer前加冠詞a。 【4】This is my car. (改為一般疑問句并作肯定和否定回答)。 答案 Is this your car? Yes, it is. /No, it isnt. 本題考查一般疑問句的構(gòu)成及答語。如果句中有動詞be(am, is, are),將動詞提到主語前,并大寫開頭字母,句末用問號,主語第一人稱變第二人稱,即變成了一般疑問句。一般疑問句要用Yes或No來回答。它的肯定答語是Yes,it is. ,不定答語是No,it isnt. 。注意答語用it代替this/that。 下面是“失物啟事”與“招領(lǐng)啟事”請認真閱讀并回答問題。 Lost My school ID card.
