倒装句是英语中的一种特殊语序结构。在正常语序中，主语在前，谓语在后。而在倒装句中，我们将谓语动词或助动词提前到主语之前。倒装句主要用于强调某些成分或满足特定的语法要求。让我们通过例子来理解这种语序变化。
当'Not only'位于句首时，我们必须使用倒装语序。倒装的具体步骤是：首先识别句子中的助动词、be动词或情态动词，然后将其提前到主语之前。如果原句没有助动词，我们需要根据主语和时态添加相应的助动词。让我们通过具体例子来看这个转换过程。
'Not only is it'句型专门用于主语为第三人称单数且谓语为be动词的情况。这种句型主要用来描述状态或特征。在倒装结构中，be动词'is'被提前到主语之前。让我们通过几个具体例子来理解这种句型的应用场景和结构特点。
In English, we often use 'Not only' to emphasize something special about a subject. But should we say 'Not only is it' or 'Not only does it'? The answer depends on what follows. Let's explore the difference between these two structures and learn when to use each one correctly.
The structure 'Not only is it' is used when we want to describe a state, condition, or quality. We use the be verb 'is' followed by an adjective or noun. For example, 'Not only is it beautiful, but also functional.' Here, 'beautiful' is an adjective describing the quality of the subject.
The structure 'Not only does it' is used when we want to describe an action or function. We use the auxiliary verb 'does' followed by the base form of the main verb. For example, 'Not only does it save time, but also money.' Here, 'save' is an action verb describing what the subject does.
Let's summarize the key differences. Use 'Not only is it' when describing states or qualities, followed by an adjective or noun. Use 'Not only does it' when describing actions or functions, followed by a base verb. Remember: 'is' for states, 'does' for actions. Practice with these examples to master both structures.
To summarize, remember this simple rule: use 'Not only is it' when describing qualities or states, followed by an adjective or noun. Use 'Not only does it' when describing actions or functions, followed by a base verb. When in doubt, ask yourself: am I describing what something is like, or what something does? With practice, choosing the right structure will become natural. Keep using these patterns in your English conversations!
