方位介词 英语 Introduction（引言） Prepositions of direction are essential elements in English grammar. They serve to indicate the position or direction of something in relation to some other object or location. In this article, we will take a closer look at some of the most common prepositions of direction used in English. Step 1: Understanding the Basics（了解基础知识） Before diving into the specifics of prepositions of direction, it is helpful to understand what prepositions are in general. Prepositions are words that indicate the relationship between a noun or pronoun and other words in the sentence. They often describe time, space, or location. In the context of direction, prepositions help to answer questions like "where?" or "which way?". Step 2: Common Prepositions of Direction（常见方位介词） There are several prepositions in English that indicate direction. Some of the most common ones are: - Above: Indicates that something is higher than another object. Example: The clouds are above the mountains. - Below: Indicates that something is lower than another object. Example: The basement is below the ground floor. - Behind: Indicates that something is located to the rear of another object. Example: The bookshelf is behind the couch. - In front of: Indicates that something is located ahead of another object. Example: The traffic light is in front of the intersection. - Next to: Indicates that something is located adjacent to another object. Example: The museum is next to the park. - Near: Indicates that something is close to another object. Example: The gas station is near the highway. There are many other prepositions of direction in English, some of which are less commonly used. Step 3: Using Prepositions of Direction in Context（如何使用方位介词） The best way to understand prepositions of direction is to see how they are used in context. Consider the following examples: - The cat is above the bed. - The bank is below the gym. - The bus is behind the tree. - The library is in front of the mall. - The playground is next to the school. - The pizza place is near the movie theater. In each of these sentences, the preposition of direction serves to indicate the position or location of one object in relation to another. Step 4: Common Errors to Avoid（常见错误） One common error in using prepositions of direction is to confuse "in" and "on". For example, it is incorrect to say "the book is on the table" when the intended meaning is "the book is in the drawer of the table". Another error is to use the wrong preposition of direction. For example, it is incorrect to say "the bank is behind the library" when the intended meaning is "the bank is next to the library". Conclusion（结论） Prepositions of direction are an important part of English grammar. They serve to indicate the position or direction of something in relation to another object or location. By understanding the common prepositions of direction and how to use them correctly in context, you can improve your English writing and communication skills.

在句尾出现的介词我们常常听人家说：不要把介词（prepositions）放在句尾，以免削弱句子的气势。

实际上，英语的介词是可以在句尾出现的；有时还是非在句尾不可。

请看这句：“I may give you financial aid. But it all depends on what the money is for .”这句话的介词“for”在句尾出现。

如果把“for”移到宾语之前，就不合句法了：*“...But it all depends on for what the money is.”这么看来，英语介词是可以放在句尾的。

既然如此，在什么情况下，英语介词才可以放在句尾呢？常见的情况有下面 4 种：㈠当疑问代词或疑问副词作为介词的宾语时，理论上要在介词后面出现，但在实际用法上，它被转移到疑问句前头，介词则留在句尾。

例如：① What are you dreaming of?② Where are you from?①不能改为“Are you dreaming of what?”也不能是“Of what are you dreaming?”②不是“Are you from where?”，更不是“ From where are you?”㈡介词不能移到限定性形容词分句中的关系代词（the relative pronoun in the restricted adjective clause）之前；因此，我们可以③表示心意，但不能用④这样的句子：③ Is this the book that you asked me for?*④ Is this the book for that you asked me?同样的，⑤是对的，⑥是错的：⑤ This is the goal that we are striving towards.*⑥ This is the goal towards that we are striving.㈢在不可分开的片语动词（the inseparable phrasal verb）里，如果介词在句尾，也只好随遇而安，不便移动。

一、概念:介词（是prepositions，简称prep)，又称前置词，是英语中最活跃的词类之一，连接主语和表语。

特别是一些常用介词的搭配力特别强，可以用来表示各种不同的意思。

英语里大部分习语都是由介词和其他词构成的。

介词在句中一般不重读。

在定语从句“介词+who/which”的结构中，不能用that 代替who/which。
