时态错误是中学生写作时普遍存在的问题。主要原因是:   
1.对各种时态的基本概念不清楚。  
2.时间立足点把握不准。   
3.母语干扰。由于汉语中动词没有“时态”的变化,许多同学在用英语表达时大脑中缺乏时态的概念,因而出现的时态错误随处可见。   
4.考场时间不够。高考英语试卷多,容量大。做到书面表达题时,时间所剩无几,匆匆完卷,根本来不及顾及时态、语态。如:   
He is working in this company ever since he was graduated from college.(误)   
析:此句应为:He has been working in this company ever since he graduated from college.
表示一段从过去开始延续到现在的时间时,主句动词应用现在完成时态或现在完成进行时态。   
二、语态错误
汉语在表达时用主动形式较多,学生往往在该用被动语态的地方用了主动语态。如: Mary was dressing in white.(误)   
析:dressing应改为dressed。英语中dress,seat等动词常用于被动语态中。   
My dog called AhFu.(误)   
析:此句应为:My dog is called AhFu.
