Microsoft Word will mark contractions like “I’m”, “don’t”, and “doesn’t”, as grammatical errors, showing that dashed line under them. For more casual documents, this can be annoying.
Microsoft Word会将诸如“我”，“不”和“不”之类的收缩标记为语法错误，并在其下方显示虚线。 对于更多的临时文档，这可能很烦人。
In certain very formal workplaces, or under very formal style guides, contractions may be considered inappropriate and too informal. That’s why Microsoft Word has this option. But, if think contractions are fine—and they are, in most situations—you can tell Word not to bug you about them.
在某些非常正式的工作场所，或在非常正式的风格指导下，收缩可能被认为是不适当的且过于随意。 这就是Microsoft Word具有此选项的原因。 但是，如果认为收缩很好-并且在大多数情况下都可以-可以告诉Word不要为它们烦恼。
