当你快速写作时，有时你使用的文字形式并不是你打算使用的形式。
当你修改作文时，认真阅读你写的文章，找出这些错误。或者请他人读你的文章，帮助找出那些表达不清楚的地方。以下是一些可能出现的词形错误的例子：
This fall in stock prices could be a foreshadow of a weakening economy is what my uncle says.
这一句应改为：
This fall in stock prices could be a foreshadowing of a weakening economy is what my uncle says.
另一个例子是：
But certain types of businesses will continue to grow to an extend, he thinks.
Extend是动词，作者本想使用它的名词形式extent。
你能在下面这句话中找到词形错误吗？
She had a puzzle expression on her face.
是的，这位作者应该把puzzle改为puzzled。
再看另一个例子：
What will happened in the near future is anyone's guess.
这位作者应该把happened改为happen。
学习词性可以让你了解每一个词在句中的作用。学习校阅自己的文章也可以帮助你提高写作能力。如果你有许多词形方面的错误，向你的老师或写作导师请教修改建议。
When you write quickly, sometimes you use a word form that is different than the one that you intended to use.
When you revise, read your writing very carefully to find these errors. Or get someone else to read your work and to help you see where you are not clear. Here are some examples of wrong word-form errors that can occur:
This fall in stock prices could be a foreshadow of a weakening economy is what my uncle says.
This sentence should read:
This fall in stock prices could be a foreshadowing of a weakening economy is what my uncle says.
Another example is:
But certain types of businesses will continue to grow to an extend, he thinks.
Extend is a verb, and this writer meant to use the noun extent.
Can you find the word form error in this sentence?
She had a puzzle expression on her face.
Yes, this writer should revise puzzle to puzzled.
One more example is:
What will happened in the near future is anyone's guess.
This writer should change happened to happen.
Learning the parts of speech can teach you how each functions in a sentence. Learning to proofread your own work could help you. Ask your instructor or writing tutor for advice if you have many errors in word forms.
