动词ing形式的用法及变化规则
动词ing形式的用法及变化规则
口诀：现在听我说，动词ing别忘了，加了ing要加be。
动词现在分词是由动词原形在词尾加ing构成的。具体规则如下：
1.一般情况下，直接在动词原形后加ing。
例如：think—thinking。sleep—sleeping。study—studying。speak—speaking。carry—carrying。say—saying。
2.以不发音的字母e结尾的单词，在加ing前要去掉e。
例如：wake—waking。make—making。come—coming。take—taking。leave—leaving。have—having。
3.以重读闭音节结尾，呈现“辅音，元音（a e i o u），辅音”结构的动词，先双写末尾的辅音字母，再加ing。
例如：shop。begin。cut。put。get。hit。run。set。sit。spit。swim。beg。drop。fit。nod。dig。et。regret。rid等。
注意：visit不是以重读闭音节结尾，不用双写。而XXX虽然重读第一音节，词尾音节不重读，但是现在分词仍要双写末尾辅音字母，然后再加ing，如：XXX。初中阶段此类词只有这一个。
4.以ie结尾的动词，把ie改为y，再加ing。
例如：die—dying。XXX—lying。
一、写出下列动词的现在分词形式：
work—working。visit—visiting。play—playing。study—studying。dance—dancing。have—having。travel—travelling。take—taking。drop—dropping。sing—singing。shop—shopping。swim—swimming。XXX—lying。
二、选择题练：
