这又是英汉两种语言的一大差别。
英语的助动词,就是起辅助作用的动词,本身没有独立的词义,不能单独做谓语,在句子中只起语法作用,和实意动词一起构成谓语(叫复合谓语),表达否定,疑问,时态,语态和其他语法关系。
其基本形式和作用如下表:原形现在式过去式过去分词现在分词作用Be Am, is,areWas,wereBeen Being 构成各种进行时态和被动语态Have Has, have Had ————构成各种完成时态do Does, do Did ————构成疑问句和否定句,加强语气,代替前面相同的动词Shall ——Should ————构成各种将来时态Will ——would ————构成各种将来时态(一)助动词be的用法1、跟现在分词构成各种进行时态:They are playing war games with toy guns and toy tanks. 他们正在用玩具枪和玩具坦克玩战争游戏。

英语助动词语法讲解
英语助动词语法讲解English:A helping verb, also called an auxiliary verb, is used together with a main verb to show the verb's tense, or to form a question or a negative. The most common helping verbs in English are "be," "do," and "have," but there are also modal helping verbs like "can," "could," "may," "might," "must," "shall," "should," "will," and "would." Helping verbs come before the main verb in a sentence, and their presence can change the meaning or tense of the main verb. For example, in the sentence "I am writing a letter," "am" is the helping verb that indicates the present continuous tense, while "writing" isthe main verb. In the question "Are you going to the store?" the helping verb "are" indicates the question form, and "going" is the main verb.中文翻译:助动词,又称为辅助动词,与主要动词一起使用,用于显示动词的时态,或构成疑问句或否定句。
主动词和助动词
主动词
• 仅由一个主动词构成——简单动词词组(Simple Verb Phrase) 例:He buys lemonade every time he goes shopping.
• 由一个或一个以上的助动词加主动词构成——复杂 动词词组(Complex Verb Phrase) 例: She is visiting Copenhagen. They have been taking music lessons.
• 又能与其他助动词搭配,像是主动词,而不完 全像情态助动词: I don’t have to buy a new car. He didn’t seem to love her.
半助动词半助动词指某些兼有主动词和助动词特征的语法结构比如have之类的结构既可与主动词搭配构成复杂动词词组并表示情态意义从而像是情态助动词
①主动词和助动词
• 英语词组按其在构成动词词组中所起的作 用分为主动词(Main Verb)和助动词 (Auxiliary)两大类。
• 动词词组是以主动词为中心的词组 • 助动词的语法功能是协助主动词表示不同
• 情态助动词表示情态意义,其过去时形式不一 定就表示过去时间
• 情态动词不能重叠使用,随后的主动词为原形 例:It may snow before nightfall. If she became a movie star, she could
afford a new home.
半助动词
• 半助动词指某些兼有主动词和助动词特征的语 法结构,比如 have to, seem to 之类的结构既可 与主动词搭配构成复杂动词词组并表示情态意 义,从而像是情态助动词: I have to buy a new car. He seems to be disappointed
