作业 13 句型转换 一、句子的种类： 陈述句 主语+谓语+宾语；主语+系动词+表语 I played football yesterday. 疑问句 be 动词\情态动词+主语+宾语；助动词+主语+实义动词+宾语 Did you play football yesterday？ 做某事：Do sth ；不要做某事：Don’t do sth Do your homework carefully.请认真做作业 祈使句 让某人做某事：Let sb do sth Let him do his work carefully.让他认真工作 让某人不要做某事：Let sb not do sth. Let him not to be careless. 请让他不要粗心 二、变否定句：我们需要通过谓语动词来体现 （1）当谓语动词是be 动词或情态动词时， 在他们后面+not * My brother can play the guitar well. →My brother can’t play the guitar well. * She is free on the weekend. →She isn’t free on the weekend. （2）当谓语动词是实义动词时，需要在它的前面＋don’t或者 doesn’t，需要注意的是，助动词后面的动词 要变回原型。 * I want to join the English club. → I don’t want to join the English club. * She goes to school by subway. → She doesn’t go to school by subway. （3）意反义词的使用，比如always和never * He is always late for school. → He is never late for school. 三、变一般疑问句： （1）当谓语动词是be动词或者情态动词时，把它们提前到主语的前面。 * Mary is free now. → Is Mary free now （2）当谓语动词时实义动词时，在主语的前面加助动词：do或者does * My mother often cleans my room in the morning. → Does your mother often clean your room in the morning * She has to do the dishes. → Does she have to do the dishes （3）要注意第一人称和第二人称的相互转换。 * I can sing and dance. → Can you sing or dance *My friend goes to bed at 9. → Does your friend go to bed at 9 四、变特殊疑问句： （1）变特殊疑问句，要把特殊疑问词放在句首，特殊疑问词的选择如下： a. 如果画线部分是物品或者某事，特殊疑问词用What b. 如果画线部分是俱乐部，特殊疑问词用What club c. 如果画线部分是时间，特殊疑问词用When或者What time d. 如果画线部分是方式方法，特殊疑问词用How e. 如果画线部分是距离，特殊疑问词用How far f. 如果画线部分是时长，特殊疑问词用How long g. 如果画线部分是in+时间段，特殊疑问词用How soon （2）当所给的谓语动词是be动词或情态动词时，把它们放在主语的前面 当所给的谓语动词是实义动词时，在主语的前面加助动词: do或does * It’s 40 minutes’ walk from my home to school. → How far is it from your home to school * He often goes to school by bus. → How does he often go to school 1．He felt uncomfortable in a room with no air-conditioner this summer.
