误:We are plant (plant) the trees in spring.
正:We plant (plant) the trees in spring.
解析:同学们往往会用汉语的思维方式去翻译,就成了“我们是在春天植树”,这是学习英语最忌讳的。在一般现在时中,be动词是表状态,行为动词是表动作,两种动词不能同时出现在句子中。
2. 第三人称单数形式易出错。例如:
误:He plaies (play) football very well.
正:He plays (play) football very well.
误:Danny gos (go) to school at 7:10.
正:Danny goes (go) to school at 7:10.
解析:以辅音字母加y结尾的动词变第三人称单数形式是把y换成i再加es。与名词变复数不同,英语毕业论文,以o结尾的动词第三人称单数形式是在词尾加es。
3. 在句式变换时易出错。例如:
误:Does Jenny has (has) a good friend?
正:Does Jenny have (has) a good friend?
误:Brian doesn’t lives (not live) in China.
正:Brian doesn’t live (not live) in China.
解析:第三人称单数作主语的一般现在时句子进行句式变化时,可记住如下口诀:“见助动,用原形”。
4. 对do的理解易出错。例如:
误:We don’t (not do) our homework in the afternoon.
正:We don’t do (not do) our homework in the afternoon.
解析:do是一个比较难理解的词,它有三个含义:a) 是所有行为动词的总称;b) 是助动词,无实义;c) 是一个具体的行为动词意为“做,干”。此句中的do表示“做,干”,not指把此句变为否定句,故须在do前加助动词don’t。
5. 对主语的 “数”判断有误。例如:
误:Li Ming with me are (be) in Beijing.
正:Li Ming with me is (be) in Beijing.
解析:表面一看是“我和李明两个人在北京”,但with me在此作状语,不能作主语,故用is。
另外,宾语从句中,从句部分若是表示客观真理,不管主句是何种时态,从句都要用一般现在时;在时间和条件状语从句中,主句表将来,从句要用一般现在时。
