四年级英语语法专项练习（二） Ⅰ一般疑问句1.把be动词（am? is? are）放到句首，其它照写。注意：?遇I/we—you,?? my—your. some—any.? 句号变成问号（？）例如： 陈述句:?? I am good at jumping rope.????? He is good at ping-pong.? 一般疑问句:?? Are you good at jumping rope???????? Is he good at ping-pong?? 2.借助助动词do/does,第三人称单数用does,其余人称用do，放到句首，其他照写。特别记住：前面用does,后面的动词一定要还原成原形。遇I/we—you, my—your, some—any. 句号变成问号（？）例如： 陈述句:?? I like roller skating.??????? He likes swimming.一般疑问句： Do you like roller skating?????? Does he like swimming? Ⅱ否定句1．?在be动词（am?,is,?are后加否定词not。如：is?not?，?are?not?，?am?not，?其中is?not=isn’t,?are?not=?aren’t2、?在can，should，will等后加not。如：can not，?should?not，?will?not； 3、上述都没有的，在动词前加助动词否定形式don’t/doesn’t/。 4、?some?改成any。 I?am?a?student.?→?I?am?not?a?student.? You?are?a?student.?→You?are?not?a?student.? I can swim very well. → I can’t swim very well. I like dancing. → I don’t like dancing. He likes roller skating. → He doesn’t like roller skating. Ⅲ肯定句改特殊疑问句对划线部分提问特殊疑问句的构成。即：特殊疑问句?=?特殊疑问词?+?一般疑问句? 掌握特殊疑问词what（对事、物提问）;who（对人提问）；where（对地点提问）；?how（对状况提问）；?how?old（对年龄提问）；?what?colour（对颜色提问）等。? 答题方法：一找二变三整理。? “一找”，即根据划线部分内容找出合适的特殊疑问句；“二变”，即把余下部分变成一般疑问句；“三整理”，即按特殊疑问句的语序整理句子，注意句首字母要大写，句尾标点为“？”。如：? ?.?→??Who?is?she?? That?is?an?orange.?→What?is?that?? I am?from?America.?→Where?are you?from?? Miss?Wu?is?fine.?→?How?is?Miss?Wu?? He?is?ten.?→?How?old?is?he?? 四步法 1、在一般疑问句的基础上，句首添加一个疑问词即可，可根据划线部分确定是什么疑问词。 2、接着找be动词或can，shall，?will等放在疑问词后面，若没有则请助动词do/does/did帮忙，写在疑问词后面，how?many除外，必须先写物品，再写be动词等。 3、划线部分去掉后剩下的内容照抄，（some?改成any，my改成your等） 4、句点改成问号。 1.
