Does Catherine like anim
29、als? Can Jenny speak French?2、往往读升调;3、译成汉语,都可以 带上“吗”,例如上面三句可分别译为:你父亲是老师吗?凯瑟琳喜欢动物吗? 詹妮会说法语吗? 二、例何将陈述句变成一般疑问句? 要将陈述句变成一般疑问句,可以遵循下列步骤: 1.看句中有没有be动词(am、is、 are、 was、 were)、助动词(do、does 、did、 have、 had)或情态动词(can、must、will、may等),如果有,将其 提到句首,句末打上问号即可。 例:It was rainy yesterday. Was it rainy yesterday? Toms f
30、ather can play the piano. Can Toms father play the piano? I have finished my homework. Have you finished your homework? .47 2.如果句中没有be动词、助动词或情态动词,则根 据谓语动词的形式借助do的相应形式放在句首。 具体方法是:如果谓语动词是原形,则借do;如 果谓语动词是一般现在时第三人称单数形式,则借 does;如果谓语动词是过去式,则借did. 需要注意 的是,借does或did后,原句的谓语动词要变回原 形。 例:They go to school by bi
31、ke. Do they go to school by bike? Bill gets up at 6:30 every day. Does bill gets up at 6:30 every day? The students saw a film yesterday. Did the students see a film yesterday? .48 三.陈述句变一般疑问句应注意的事项 陈述句变成一般疑问句除了遵循上述规则以外,还应注意下列几点 : 1.如果陈述句中有第一人称,则变问句时最好要变为第二人称。 例:I usually have lunch at school. Do yo
32、u usually have lunch at school? My father is playing soccer. Is your father playing soccer? 2.如果陈述句中有some, 则变问句时往往要变成any 。 例: There is some water on the playground. Is there any water on the playground? 3.复合句变一般疑问句通常只变主句,从句不变。 例:I know he comes from Canada. Do you know he comes from Canada? 4如果句中含有实
33、义动词have且表示“有”时,除借do外,也可将 其直接提到句首。 例:I have some friends in America. Have you any friends in America?/Do you have any friends in America? .49 四.一般疑问句的回答 一般疑问句往往采用简短回答,共由三部分(三个单词)组成,对这三部 分(三个单词)的确定可以概括例下: 1.第一个词:不是Yes就是No。(有时根据语气的不同,Yes可由Sure, Certainly, Of course等代替.NO可由sorry 代替.) 2.第二个词:问谁答谁。即答语中的主语
34、须与问句的主语一致(但必须用 主格代词)。 例:Does she clean her room every day? Yes, she does. Is Annas father a doctor? No,he isnt. 如果主语是 this that,回答时用 it 代替,如果问句中主语these, those,回答 时用 they 代替。 3.第三个词:用什么问,用什么答。即沿用问句中的引导词。 Can Jim play soccer? Yes, he can./Does Mr Bean speak English? Yes, he does. 需要注意问题:(1).用 may 引导的问句,肯定回答用may,否定 回答用 cant 或mustnt,用 must 引导的问句,肯定回答用 must,否定回答 用neednt. 例:May I go to the park now? Yes, you may. /No, you mustnt. Must I wash my clothes now? Ye
