托福口语中需要防止的原则性错误

大家一块儿看下面的托福口语例子：

My teacher gave interesting assignments andmotivating the students.

非常显然，这个托福考试口语错误是混用语法结构的一个典型。这会使句子产生歧义：难道是说My teacher gave interesting andmotivating assignments to the students? 由于本句中interesting和motivating 是平行结构. 或者是My teachergave interesting assignments and motivated thestudents? 由于亦可以理解成gave和 motivated是平行结构.所以错误用语法会带来很多意料之外的麻烦。

当大家重复用一个短语或单词的时候，不只会给人以词语量过小的感觉，有时甚至也会导致误解，这对于托福口语分数是非常有影响的。大家来看一个例子：

My teacher wrote the assignment on the chalkboard. The assignment was on thechalkboard until the teacher erased the assignment after we had all done the assignment.事实上这句话的看法会愈加明确，假如大家将重复的词替换为其他表达的话。大家再来看看改进后的表达：

My teacher wrote the assignment on the chalkboard. She erased the board after we had allcompleted the task.

其中 assignment 被替换为 task; teacher 变为了she; chalkboard 被改为了board. 不但句子看上去愈加生动活泼不刻板，信息量也比原来要多了。

通过上面的介绍相信大伙可以发现托福考试口语中绝对不要犯一些原则性的错误，这对于托福口语分数是非常致命的，期望能帮大伙托福口语有所提高。
