4、u.Andthatismy_,Tim:AndJane,isthisyour_?,Jane:No,itisnt.Itsherruler.,Tim:OK,andthisismy_.,Andthisisyour_,Jane.,eraser,ruler,book,pencilcase,pencil,是以be动词(is,are等)，情态动词(can等)或助动词(do,does等)开头表示疑问的句子。对一般疑问句的回答通常需要作肯定或否定回答。,一般疑问句：,巧变一般疑问句,秘诀：一调二改三问号一调：即把句中的be（am/is/are)调到主语的前面。二改：句中的主语若含有I(my/we)等第一人称代词时

5、，需将它们改为you(your/you）三问号：句末的句号改为问号。,Yes,itis./No,itisnt.,它们是一般疑问句简略的答语。肯定答语：Yes,主语+be.否定答语：No,主语+be+not.2.简略答语的主语要由问句的主语来决定。若问句中主语是that或this，答语的主语用it.若主语是名词时，答语的主语应用相应的人称代词。,如何将含be动词的肯定句变为否定句,一般将含be动词am,is,are的肯定句转化为否定句时，直接在be动词am,is,are后加上“not”即可。其他部分不变。e.g.1.Thisisaruler.变：Thisisnotaruler.2.Iamastu

6、dent.变：Iamnotastudent.3.TimandIaregoodfriends.变：TimandIarenotgoodfriends.,口诀,be动词真伟大，生出amisare.表示否定很简单，not加在be后边。若要变为疑问句，be应移到主语前。还有一点要注意，句末问号别忘记。,be动词用法口诀,我(I)用am，你(you)用are，is连着他(he)，她(she)，它(it)，其余单数用(is)，复数就用are。,一、将下列句子变成一般疑问句和否定句1.Thisisanapple.2.Itsmycomputer.3.Thisismybackpack.4.Myphonenumbe
