错误一：时态

针对这个问题，可能你的口语老师会教你用the reason why I…is that…这个句型来回答。但所有考生在第一次作答时，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.

错误二：there be句型与have/has混杂使用

看以下及组形容 词：interesting与interested;exciting与excited;surprising与surprised。什么叫形容人?基本上来讲，可能出现的情况无非以下两种：a. somebody + be动词 + 以ed结尾的形容词 + 介词 + something 如：I‘m surprised about this piece of news. b. something make(s) somebody + 以ed结尾的形容词 如：This piece of news makes me surprised. 什么叫形容一件事或一种东西?也就是：a. something + be动词 + 以ing结尾的形容词 如：This piece of news is surprising. b. 以ing结尾的形容词 + 名词 如This is a surprising piece of news.

错误五：动词短语忽略成分

有些动词短语的搭配是固定的，只有把短语完整的说全的情况下才可以接之后的名词，但许多考生很容易忽视这一点。如：listen to, go to, look forward to, pay attention to等等。所以我们要在练习中尽可能的回忆当时学校课堂上所交的那些口诀，来确保每一个说出的动词短语不会遗忘任何成分。

错误六：情态动词后不加动词原形

有的考生会因为过度重视时态问题，如一味的想着整个作答都要基于某种时态而忽略情态动词后要加动词原形这一原则。如I thought the reason why I chose to study that subject was I could got a better job after learning that。而正确的说法则是I thought the reason why I chose to study that subject was I could get a better job after learning that.
