1.易错记动词的现在分词，
【例题】改错。
( )(1) Mum is makeing a cake in the kitchen. ________ 【来源：21·世纪·教育·网】
A B C
( )(2) Tom is runing in the playground now. ________
A B C
【答案】(1) B making a cake (2) B running
【点拨】现在_è??è??????????¨è??_的现在分词的构成规则主要有：一般情况下在动词词尾加-ing； 以不发音的字母e结尾的动词,先去掉e,再加-ing；末尾只有一个辅音字母的以重读闭音节结尾 的动词，先双写末尾的辅音字母.再加-ing；以字母组合ie结尾的动词,先将ie变为y.再加-ing。 题(1)中make的现在分词变形应该是先去掉尾字母e,再加-ing,故选B.改成making a cake.题 ⑵中run的现在分词变形应该是先双写末尾的辅音字母n,再加-ing.故选B.改成running0
2.易将进行时态的句子结构弄错。
【例题】根据上下文或中文提示完成对话。
(1)What are you doing. Sam?
________watching TV.
(2)What is Lucy doing?
She is________(给... 浇水)the flowers.
【答案】 (1) I'm (2) watering
【点拨】 现_??¨è??è????????é??_述句结构是“主语+ be动词+现在分词."?所以be动词和现在分 词缺一不可。题(1)对于此类问句的答句应该是I'm/We are+现在分词问句中有人名Sam, 所以是Sam 一个人回答.故填I'm。题(2)根据问句可知是现在进行时态.设空处需要填动词的现在分词.water the flowers意为"浇花",故填 watering。
3.易混淆动词wash和clean的用法
【例题】根据中文提示完成句子。
(1)你的妈妈现在正在洗衣服吗？ 是的。
________ ________ mother________ ________now?
Yes, she is.
(2)我的爸爸正在打扫房子。
My father________ ________ the house.
(3)海伦在家经常洗碗。
Helen ________ ________ ________often at home.
【答案】 (1) Is you_r,_was_hing clothes (2) is cleaning (3) washes the dishes
【点拨】 wash和clean_?????¨è????¨??????_都有将某物弄干净的意思.但二者有所区别：wash通常 指用水、洗涤剂、肥皂等洗掉物品或身体某一部分的脏东西：而clean则更强调除去灰尘、打扫、擦 净，并不注重采用哪种清洁方式。题(1)和题(3)中所洗的对象 “衣服”和“碗”都需要浸泡在水中， 须用wash来表示。题(2)中的“打扫房子”通常指去除灰尘，须用clean来表示。21教育网
