be 动词专项练习 小升初英语(知识讲解+专项练习) be 动词在英语中是非常重要且基础的一类动词,其基本形式有 am、is、are,过去式有 was(am/is 的过去式)和 were(are 的过去式)。它在不同时态和句式中有着多样的用法。 一般现在时: 当主语是第一人称单数 I 时,be 动词用 am。例如:I am a student.(我是一名学生。) 当主语是第三人称单数(he/she/it,或单个的人名、地名、事物名称等)时,be 动词用 is。例如:He is tall.(他很高。)The book is on the desk.(书在桌子上。) 当主语是第二人称 you,以及第一、二、三人称的复数(we/you/they)时,be 动词用 are。例如:You are kind.(你很友善。)They are happy.(他们很开心。) 一般过去时: 当主语是第一人称单数 I 和第三人称单数(he/she/it 等)时,be 动词的过去式用 was。例如:I was at home yesterday.(我昨天在家。)She was late for school.(她上学迟到了。) 当主语是第二人称 you,以及第一、二、三人称的复数(we/you/they)时,be 动词的过去式用 were。例如:You were in the park last week.(你上周在公园。)They were busy last month.(他们上个月很忙。) 一般将来时: 常见结构为 “be going to + 动词原形”,其中 be 动词会根据主语的人称和数进行变化。例如:I am going to visit my grandparents.(我打算去看望我的祖父母。)He is going to play football.(他打算去踢足球。)They are going to have a party.(他们打算举办一个派对。) 另一种结构是 “will + 动词原形”,此时 be 动词用原形 be。例如:It will be sunny tomorrow.(明天将会是晴天。)We will be there on time.(我们会准时到那里。) There be 句型: 表示 “某地有某物 / 某人”,be 动词的形式要根据其后最靠近的名词的单复数来确定。如果是单数名词或不可数名词,be 动词用 is;如果是复数名词,be 动词用 are。例如:There is a book on the desk.(桌子上有一本书。)There are two pens in the pencil - box.(铅笔盒里有两支钢笔。)当出现多个名词时,遵循 “就近原则”,如:There is a cat and two dogs in the room.(房间里有一只猫和两只狗。) be 动词在疑问句和否定句中的变化: 一般疑问句:将 be 动词提到句首,句末用问号。例如:Is he a teacher (他是一名老师吗?)Are they students (他们是学生吗?) 否定句:在 be 动词后加 not。例如:He is not (isn't) at home.(他不在家。)They are not (aren't) happy.(他们不开心。) 小升初 be 动词专项练习 一、用 be 动词的适当形式填空(每空 1 分,共 20 分) I _____ a student.
