1、名词错误 名词单、复数用错,可数与不可数名词的混用。 例如: ①We study quite a few subject, such as maths, Chinese, English and physics.? A few后面应该用复数,所以subject改为subjects。 ②They were eager to know everything about China and asked me lots of question. Question为可数名词,lots of后面是复数形式,所以question改为questions ③I hope that you two could come and visit us some times soon. “Times”表示次数时是可数名词,表示时间概念时是不可数名词,根据句意times应改为time。 2、时态错误 在一篇结构完整、语义连续的短文中,时态的使用也应该连贯一致,但是英语表示时间时,主句和从句时态可能不一致,却仍表明完整正确的意思。这就要求考生准确判断句中动作的时态,培养对英语时态的敏感度。 例如: ①He can’t remember what he once knows. 主句用的是一般现在时,宾语从句中有once(从前)作为明显的时间状语,因而从句中动词应用过去时knew。 ②It was kind of them to meet me at the railway station and drove me to their home. “and”两边应该是平行的,“and” 前面是动词原形meet,“and”后面应该也用动词原形,所以将drove改为drive。 3、语态错误 在PETS二级短文改错题中最常见的语态错误是被动语态被误用为主动语态。因为汉语表达习惯上有时不加“被”字也能表示被动,因而造成考生对被动语态不敏感。另外,不及物动词不能携带宾语,因而也没有被动语态。 例如: She was very angry at not telling the truth when she listened to the account. 意思是:当她听这个叙述的时候,她很生气没有被告知真相。这里“她”是被告诉的对象,因而telling应改为being told。
