一般现在时 【概念引入】 在英语中，不同时间发生的动作和情况，要用不同的动词形式表示，这种不同的动词形式叫做动词的时态。今天我们要学习的是一般现在时。 【用法讲解】 一、一般现在时的使用范围。 1. 表示现在的状态。 例如：I’m twelve. 我十二岁。 Where’s the schoolbag? 书包在哪里？ 2. 表示经常或者习惯性的动作。 例如：I have lunch every day. 我每天吃午饭。 Gina always asks: “Where is my schoolbag?” Gina总是问：“我的书包在哪里啊？” 3. 表示客观事实或者存在。 例如: My sister is a teacher. 我姐姐是一位老师。 The earth turns around the sun. 地球绕着太阳转。 4. 表示主语所具备的性格和能力。 例如：She likes English very much. 她很喜欢英语。 Bill likes beef, but he doesn’t like chicken. 比尔喜欢牛肉但是不喜欢鸡肉。 以上所述均是一般现在时的基本使用范围，除此之外一般现在时还有其他一些特殊用法，比如:一般现在时可以用在一些从句中表将来等，我们会在以后的学习中讲到。注意： 一般现在时态经常与often（经常），sometimes（有时），always（总是），usually（通常）等副词连用，也经常与every day（每天）, every week（每周）, every month（每月）, every term（每学期）, every year（每年）, once a week（一周一次），twice a year（一年两次）等时间状语连用。 例如：She gets up early every morning. 她每天早上早起。 I go to see my grandmother every month. 我每个月都去看我的奶奶。 二、谓语动词在一般现在时中的使用情况。 一般现在时态分为be动词的一般现在时和实义动词的一般现在时。 1．动词be的用法 be动词包括“am，is，are”，中文意思为“是”。这三个词的用法要随着主语的变化而变化。“am” 用于第一人称单数（I）；“is” 用于第三人称单数（he，she，it），以及单数可数名词或者不可数名词前; “are”用于第一人称复数（we），第二人称单数和复数(you), 第三人称复数（they）。 例如：I am a student. 我是个学生。 He / She is a student. 他/她是个学生。 We/They are students. 我们/他们是学生。 You are my teacher. 你是我的老师。 You are my teachers. 你们是我的老师。 be动词用法歌诀： 英语有个动词be，“面孔”不同要注意；
英语一般现在时结构归纳 英语是我们在很多地方都通用的哦，今天小编就给大家分享一下英语的知识大全，欢迎大家阅读 英语知识 常用结构： 1.主语+谓语+其他(表动作) It never snows in Australia in December. 澳大利亚的12月里从来不下雪。 They usually go to school by bike. 他们通常骑自行车上学。 He writes to his father twice a month. 他每月写两次信给他爸爸。 2.主语+be+表语(表状态) He is a student. 他是学生。 ⅠBe动词的一般现在时 主语+be(am , is , are)+其它 肯定句式:主语+be( am, is, are)+其它. 如，The color is blue. 否定句式:主语+be(am, is, are) +not +其它.如，The color is not blue.
一般疑问句:Be(am, is, are) +主语+其它?. 注:在这种构成中，be动词有人称和数的变化，即要根据主语选用am / is / are。Be动词分为单数和复数，am和is是表示单数，am只跟I搭配(除了I其余的单数都用is)，are表示复数。 Ⅱ实义动词的一般现在时 ①主语(第三人称单数)+动词(第三人称单数形式)+其它 肯定句式:主语(第三人称单数)+动词(第三人称单数形式)+其它，如，He likes it 否定句式:主语(第三人称单数)+doesnt+动词(原形)+其它.如：He dosent like it. 一般疑问句:Does+主语(第三人称单数)+动词(原形)+其它?
