托福口语和写作部分都对考生的词汇Vocabulary有明确的要求，Speech Rater和E-Rater这两个评分引擎将会评估考生的词汇量，如果频繁使用不准确的、表意模糊的词会表明你的词汇量有限，从而影响2个部分的分数。

Very / so

Very这个词在英语表达中“very”是一个力度很低的词语，“very”的频繁使用不仅会让考官觉得无聊，还显示出了考生贫瘠的词汇量，甚至有的时候very并不能给句子加分，比如：My mother is very caring 和 My mother  very caring 两句的表达其实是没有因为very产生不同。

所以，别再用毫无新意的very了，如果你的确有频繁使用very的习惯，可以在口语写作的练习中加以重视，适当使用一些替换词，逐步取代单调的very+形容词表达法，如：

very afraid terrified

very boring  dull

very careful  cautious

very cold  freezing

very difficult  challenging

Of course

不建议使用of course的原因有两个，因为这样的过渡会暗示你的读者以及听众并不聪明，或者你并没有充分解释你的想法。

Of course,living in a dorm is a lot less expensive than living in an apartment.

Clearly, living in a dorm is a lot less expensive than living in an apartment.

Thing / Stuff

使用“thing”或“stuff”意味着你不知道如何描述一个物体或一些现象，暴露了自己的词汇匮乏，所以建议考生一定要学会用详细的词去进行描述表达。

Finally, I have taken my things to my new dorm.

Finally, I have taken my belongings（财物）to my new dorm.

The stuff in the meeting lasted more than two hours.

The proceedings（事件）in the meeting lasted more than two hours.

Always

使用always是典型的夸大了论点中的观点，因此，不建议托福考生使用这个副词，可以尝试替换为usually 。

My roommate always throws his clothes on the floor.

My roommate usually throws clothes on the floor.

Never

这里特意指出，never和always有相似的问题，never也容易夸大。

My roommate never lost her temper because she was a good person.

Instilled in her that being angry was an unacceptable form of human expression, my roommate rarely lost her temper.

A lot

在关于数量的表达中，也要做到用词，并且正式，在写作中，a lot of/lots of表示为“许多”，较为不正式，除了使用many或者much来表达，还可以恰当的使用a plethora of进行表达。

A  lot  of books are piled onto the bookshelves by the wall.

A plethora of（过多的）books are piled onto the bookshelves by the wall.

Good

在托福口语写作中小伙伴们是不是还在用 good？你的词库真的该更新啦！这些词不仅仅简单基础，无法体现出你的词汇量，也不能表示事物不同程度的“好”。

My TOEFL mentor was a good help to when while I was completing my speaking and writing practice tests.

My TOEFL mentor was a splendid（的）help to when while I was completing my speaking and writing practice tests.

Nice

和前面很多词的问题一样，nice也是一个表意模糊不准确的词，而对于想取得高分的托福考生来说，应该选择更加准确的词来表达。

For these reasons, I have usually found my mother to be nice.

For these reasons, I have usually found my mother to be cordial（亲切的）.

Really

Really的问题像开头提到的very和so，是一个不太精确表达程度的词，所以建议大家可以用更高 级的词汇替换表达：

I told my friend that it was really important to talk to the professor if he had questions about his final term project.

I told my friend that it was distinctly important to talk to the professor if he had questions about his final term project.

Anything

Anything可以是一切事物，这种不准确的用词描述尽量不要出现在托福考试中，考生们需要学会详细描述事物，展开解释anything这个词也会让你的论据更加充分。

I would do almost anything in order to live with a compatible roommate.

Interviewing several people before making my choice, requiring references, and making sure the chosen candidate gives me a $2,000 deposit will ensure that I can select the most qualified person to live with me.

通过以上这些词不难看出，托福考试的用词还是以准确、不模糊语义为出发点，在此基础上再使用恰当的高 级词汇，但是一定要弄清词意与语境才运用，也要注意不同单词在表达程度和感情色彩上的区别。
