七上译林版Unit 2 Hobbies 行为动词的一般现在时 1.概述 一般现在时表示经常性或习惯性的动作、目前的爱好、能力等以及不受时限的客观事实。这时我们常使用行为动词的一般现在时(包括动词原形和动词三单）。 一般现在时的标志词：always ,often,usually,sometimes, seldom, never等频率副词或every morning/ evening day/week/year, in the morning/afternoon/ evening等时间状语连用。 【Note】用一般现在时进行表达时，不能同时使用 be动词和行为动词。 2. 行为动词的一般现在时的用法 三单：第三人称单数形式，即非你非我单数形式 ①如果主语是非三单，行为动词用原形。 I often play football. 我经常踢足球。 They usually have bread and milk for breakfast.他们通常早餐吃面包和牛奶。 ②如果主语是三单，行为动词用三单形式。 Mike usually goes to school by metro. 迈克通常坐地铁去上学。 判断主语是否三单两种方法：①将主语转化成人称代词，若转化后为he, she, it，则为三单；②排除法，主语非你非我，又是单数，则为三单。 Note: ①不定代词（someone/anything等）以及指示代词this，that;动名词、不定式作主语为三单形式； ②of短语看of前的核心名词；时间、金钱、距离作整体时看作单数；either/neither of +复数名词正式用法用作单数；集体名词（team, group, family等）整单个复。Who/what疑问代词作主语通常单数，需根据实际判断。 3.行为动词一般现在时的句式结构 句式 结构 例句 肯定句 主语+动词的第三人称单数形式/动词原形+其它 Jane likes dogs. 简喜欢狗。 They usually finish homework before dinner. 他们通常在晚饭前完成作业。 否定句 主语+don't/doesn’t+动词原形+其它 I don't like cats. 我不喜欢猫。 My sister doesn’t brush teeth in the evening. 我妹妹晚上不刷牙。 一般疑问句 Do/Does+主语+动词原形+其它？ 肯定回答： Yes,主语+do/does. 否定回答： No,主语+don’t/doesn’t. 一Do you like hamburgers?你喜欢汉堡吗？ Yes, I do./No, I don’t.是的，我喜欢。/不,我不喜欢。 — Does he go to work by car? 他开车上班吗？ —Yes, he does. 是的，他是。 —No，he doesn’t. 不，他不是。 4. 动词第三人称单数的变化规则： 一般情况在动词末尾直接加“s” say-says; read-reads; play-plays; get-gets 以x,sh,ch,s结尾的动词，加 “es” fix-fixes; brush-brushes; teach-teaches; dress-dresses 以辅音字母加o结尾，加 “es” do-does; go-goes 以辅音字母加y结尾，变y为i，再加 “es” study-studies; fly-flies 特殊变形 have-has 5. 口诀巧记忆 动词三单变形口诀 动词三单现在时，一般词尾加s, sh、x、ch、s连词尾（西施吃蛇），直接加上es,词尾辅音加个o, 选择加上es, 辅音加y来结尾，变y为i有道理，es后面紧跟随。 6. 做题方法步骤 一找二断三变形 ①找出主语并圈画出；②判断主语是否为第三人称单数，这里有两个方法来判断：(1)主语若为名词，用代词来代替，判断代词是否为it, he, she; (2) 排除法，判断主语是否排除you, I 或者复数；③确定行为动词是否变形，为三单，根据口诀变形；不是三单，动词不变形。 即学即练 1. My brother often ____（watch）TV on Saturday evening. 解析：①圈出主语My brother; ②判断主语是否为三单，my brother用代词代替是he, 属于三单；③动词改为三单形式，根据口诀：sh, x, ch,s 连词尾，直接加上es, watch以ch结尾，加es,变为watches. 答案： watches 2. The apples ________ (look) yummy. 解析：①圈出主语The apples；②判断主语是否为三单，the apples用代词代替是they, 不属于三单；③主语非三单，动词用原形，所以此处用look. 答案： look 跟踪训练 1、 单项选择(本大题共20小题) 1.
