No,it isnt. Its a pen. 不,不是。是钢笔。 Are these your books? 这些是你的书吗? Yes,they are. 是的。 (2)一般疑问句 以动词be,have或助动词、情态动词开头,以yes或no作回答的问句叫做一般疑问句。回答时可以用完整的句子回答,但大多数情况下只需作简略回答。如: Is this your pencil? 这是你的铅笔吗? Yes,it is.是的。 Have you any magazines? 你有杂志吗? Yes,I have.有。EXERCISES 【1】Heres exercise-book. A. a B. an C. two D. 句中的a和an都是不定冠词,放在单数可数名词前,修饰限定名词,表示“一个、一块”的意思。如果名词的读音以辅音音素开头,用不定冠词a,如:a banana, a pear;如果名词的读音以元音音素开头,要用不定冠词an,如an orange,an egg。在本句中,book是可数名词单数,用冠词a,而单词exercise是以元音音素“e”开头的词,故要用冠词an。 【2】根据上下文,在空格上填上一个恰当的词。 (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)本题是以be为谓语的一般疑问句,主语是you,应填Are;答句主语是I,填am。 (2)当前后两句表述的意思相同,仅主语不同时,在句末逗号后应填上too,表示“这是,那也是”。 (3)Its是It is的缩写形式,It指代this。由于No后面用的是句号,且后面的句子是一个完整的句子,应看做为一个独立的句子,故its应大写第一个字母。 答案 (1)Are; am (2)too (3)Its 【3】从下面各句A、B、C、D中找出一处错误并改正。 (1)Thats a Chinese car. A B C D (1)Chinese,Japanese,English等词均属专有名词,书写时要将第一个字母大写,应改为Chinese。 (2)That is a pencil box. A B C D (2)英语中有部分单词是由两个词构成的,在两个词之间须加连字符号“-”,所以应改pencil box为penhcil-box,同学们在学习时要多加注意。 (3)Whats this in English? A B Its computer. C D (3)有些同学在学习时没有注意汉语和英语表达不同,仅从汉语的角度去理解英语,所以在名词前面就缺少了冠词,应在computer前加冠词a。 【4】This is my car. (改为一般疑问句并作肯定和否定回答)。 答案 Is this your car? Yes, it is. /No, it isnt. 本题考查一般疑问句的构成及答语。如果句中有动词be(am, is, are),将动词提到主语前,并大写开头字母,句末用问号,主语第一人称变第二人称,即变成了一般疑问句。一般疑问句要用Yes或No来回答。它的肯定答语是Yes,it is. ,不定答语是No,it isnt. 。注意答语用it代替this/that。 下面是“失物启事”与“招领启事”请认真阅读并回答问题。 Lost My school ID card.
