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．
