四年级英语时态总复习

时态总复习NameDate时态一：现在进行时现在进行时主要表示现在或现在这一阶段正在进行的动作。它的构成形式是：助动词be＋动词的现在分词（Verb-ing）。A．将现在进行时的肯定句改为否定句，只要在助动词be后加not。B．把现在进行时的肯定句变为一般疑问句，只要将助动词be放在主语前面，回答时与其他一般疑问句一样，也用yes或no表示。现在分词的构成方法有三种：1．一般在动词词尾＋ing，如：go-going。2．以不发音字母e结尾的动词，先去掉e，再加ing，如：write-writing。3．动词词尾是一个辅音字母重读闭音节的词，一般先双写最后一个辅音字母，再加ing，如：stop-stopping。现在进行时练习：汉译英1．我们在河边唱歌。。2．你们不在上课。你们在干什么？。3．汤姆在画画吗？不在。。4．他的父亲在看报吗？是的。。按要求改写句子1.Theboyisplayingbasketball.否定句：____________________________一般疑问句：_________________________肯定回答：__________________________否定回答：__________________________对“Theboy”提问：__________________________2.仿照例句造句:Model:read,abook--Whatareyoudoing?--I'mreadingabook.1).read.anewbook.________________2).cleantheblackboard.________________4.She,thewindow,opens,now.(用现在进行时连词成句.)_________________________________5.Thebirdsaresinginginthetree.(就划线部分提问)____________________________________6.Is,who,thewindow,cleaning?(连词成句)________________________________7.Thechildrenareplayinggamesnearthehouse.(就划线部分提问)_______________________________________________8.Sheisclosingthedoornow.(改成否定句)______________________________9.Youaredoingyourhomework.(用"I"做主语改写句子)_______________________________10.They,thetree,sing,now,under.(用现在进行时连词成句.)____________________________________11.TheYoungPioneersarehelpingtheoldwoman.(改成一般疑问句)________________________________________________时态二：一般现在时一般现在时表示现在的一段时间内经常发生的动作、存在的状态。一般现在时的构成谓语动词的人称变化：当主语是第一人称、第二人称或第三人称复数形式时，谓语动词要用动词原形。当主语是第三人称单数形式时，谓语动词用第三单数形式，即动词词尾要加-s或-es。例：Wehavefourclassesinthemorningeveryday.Theymakeprogresseveryday.Shelikessingingverymuch.动词的第三人称单数形式变化可分为规则变化和不规则变化两种情况：1．规则变化①一般直接在动词词尾加-s。例：ask→asks/work→works/get→gets/stay→stays②以字母s,x,ch,sh或o结尾的动词，在词尾直接加-es。例：watch→watches/wish→wishes/fix→fixes/do→does/go→goes/pass→passes③以辅音字母加-y结尾的动词，要先变y变i再加-es。例：try→tries/study→studies/cry→cries/fly→flies2．不规则变化例：be→is have→has一般现在时练习：单项选择
