英语主语和谓语的调整定语和状语的调整 英语句子结构的调整是语法灵活性的体现，同时也是表达需要的结果。这种调整不仅影响了句子的整体意义和语气，还对主谓一致性产生了重要的影响。主谓一致性是英语语法中的一个基本原则，指的是句子中的主语与谓语在数（单数或复数）和人称（第一人称、第二人称或第三人称）上必须保持一致。在句子结构调整的过程中，主谓一致性的规则同样适用，但可能需要进行相应的变化以适应新的句子结构。 句子结构调整主要包括主语和谓语的调整、定语和状语的调整以及从句的调整等。这些调整可以通过添加、删除或重新排列句子成分来实现。 1. 主语和谓语的调整 主语和谓语的调整是最常见的句子结构调整方式。主语是句子的核心，谓语则描述了主语的行为或状态。在调整句子结构时，主语和谓语的位置和数量可能会发生变化，从而影响到主谓一致性。 例如，将陈述句转换为疑问句时，主语和谓语的位置会发生变化。原句“They are playing football.”中的主语是“they”，谓语是“are playing”。转换为疑问句“Are they playing football?”后，主语和谓语的位置颠倒，但主谓一致性仍然保持不变。 新概念英语mp3 高中英语单词听力 新概念英语mp3下载 人教版初中英语mp3 2. 定语和状语的调整 定语和状语是句子的修饰成分，它们可以调整句子的细节和语境。在调整句子结构时，定语和状语的位置和数量也可能会发生变化。 例如，在将简单句扩展为复合句时，可以通过添加定语或状语来丰富句子的内容。例如，原句“She is a teacher.”可以通过添加定语来扩展为“She is a dedicated teacher.”在这个例子中，定语“dedicated”的添加并没有改变主谓一致性的规则。 3. 从句的调整 从句是句子中的一个完整句子，它可以作为主语、宾语、定语或状语等成分出现在主句中。在调整句子结构时，从句的位置和类型可能会发生变化。 例如，在将陈述句转换为复合句时，可以通过添加主语从句或宾语从句来实现。例如，原句“I like music.”可以通过添加宾语从句来扩展为“I like the music that sounds beautiful.”在这个例子中，宾语从句的添加并没有改变主句的主谓一致性规则。 When something on your fruit or vegetable looks strange，it isn't unusual to throw it to the side without any hesitation.But some "unusual" parts of fruits and vegetables actually contain abundant amounts of health benefits or they may offer other little﹣known uses.Those strings in your banana are no different.     Often thrown away with its skin，banana strings，which are scientifically called phloem bundles，are just as nutritious as the rest（inner part）of the fruit.They are packed full of fibre，vitamin A，and vitamin B6 and other nutritional content.Phloem can be found in all plants，which is responsible for the transport of nutrients. "Phloem bundles are made up of living cells that send food products and sugar to all the different parts of the plant，" says Rebecca Lee，a registered nurse and the founder of remediesforme.com.And that is exactly what those strings do in the banana，transporting necessary nutrients throughout the delicious fruit so that it can grow up properly.     "They are not disgusting，and they just help the banana grow and become delicious，" Dr.Elizabeth Trattner A.P.DOM，Doctor of Chinese and Integrative Medicine，told Reader's Digest."It is fine to eat and although its structure is a little different from the inside."     Those phloem bundles can also be used to determine if your banana is ready to eat.If all of the nutrients haven't been transported completely in a balanced way throughout the fruit yet，then the phloem bundles stay on more tightly，meaning the banana is under ripe.Then the opposite occurs with ripe and over﹣ripe bananas，as the strings can be removed more easily.But if your bananas do end up being over﹣ripe，throw them away？Absolutely not! （1）What are the strings of a banana？       A.Its nutrition producers.
