雅思口语易错点之时态

　　时态错误可以算语法错误中低级而又最不易发现的两种了。它的低级是因为时态是所有考生在笔头上都已掌握的很好;但一转到口头上，就很难保持了。请看以下的例子：

　　Part I问题：Why did you choose to study that subject?

　　针对这个问题，可能你的雅思口语老师会教你用"the reason why I…is that…"这个句型来回答。但所有考生在第1次作答时，基本上都会忽略所提出问题的时态，而在作答时用一般现在时来回答：The reason why I choose to study this subject is that I am interested in learning it at that time。

　　很显然，正确的回答应该把句中的choose变为chose，is变为was，am也要相应的变成was：如：The reason why I chose to study this subject was that I was interested in learning it at that time.
