They are at a camping site.为什么用at ,可不可以这样,They are a camoing site.
不可以,意思就变了
前句意思 是他们在露营地
后句意思是 他们是露营地
介词不可以省略的
再问： BE动词，我不知道如何使用，什么时候用，什么时候不用，谢谢!
再答： Be有两种形式 第一，系动词，所构成的句子结构为主系表，表现形式有：is, am, are, was, were，在句子中翻译为“是” 如： I am a girl. 我是个女孩。 第二，助动词，无实际意义，与其他动词一起构成时态。表现形式有：is, am, are, was, were以及Be原形。 如： I am reading. 我正在看书。（进行时） be动词的用法 be [bi:] vi 现在时 I am, you are, he is, we are, you are, they are （缩略式 I'm, you're, he's, we're, you're, they're）, （否定缩略式 I'm not, isn't, aren't）, 过去时 I was, you were, he was, we were, you were, they were （过去时否定缩略式 wasn't, weren't）, 过去分词 been, 现在分词 being 英语的“be”是个特别动词；有些语言，如中文和马来文，并没有“be”这样的动词。 “Be”除了原形的“be”之外，还有另外七种形式：am, is, are, been, being, was, were. 在句子中，“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb). 【当主动词时，“be”在性质上属于接系动词(The Linking Verb), 后面要有名词、形容词、地方副词或短语作补足语(The Complement)。例如： 1. The man is a science teacher. 2. Mary's new dresses are colourful. 3. I have been there before. 4. Mother is in the kitchen now.
