1、动词第三人称单数的变化规则及练习一、 使用情况：在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。(标志词usually often always sometimes never every等)二、变化规则1、直接在动词后+s 例如： like- likes play-plays 2、以s, x, sh, ch, 接尾的动词：+es 例如： wash-washes3、以辅音+o接尾的动词：+es 例如： go-goes4、以辅音字母+y接尾的动词：变y为i+es 例如： fly-flies以元音字母+y接尾的动词后+s例如：play-play
2、s5、除上述规律外，还应注意下面三点： 1) 动词 have ，遇到主语是第三人称单数时，要用 has； 动词 be 的第三人称单数形式是is。 2）含有动词第三人称单数形式的句子变否定句时，要用 doesnt + 动词原形，如： He goes to school at six in the morning. (变否定句) He doesnt go to school at six in the morning. 3)对含有动词第三人称单数形式的句子提问时，要用助动词 does如： She goes home at five every day. (对划线部分提问) When / What

17、encil? (把主语改成she) _ _四、动词的适当形式填空Jims father (work) in a bank. He (go) to work by bus every morning, sometimes he (ride) his bike. “教书先生”恐怕是市井百姓最为熟悉的一种称呼，从最初的门馆、私塾到晚清的学堂，“教书先生”那一行当怎么说也算是让国人景仰甚或敬畏的一种社会职业。只是更早的“先生”概念并非源于教书，最初出现的“先生”一词也并非有传授知识那般的含义。孟子中的“先生何为出此言也？”；论语中的“有酒食，先生馔”；国策中的“先生坐，何至于此？”等等，均指“先生”为
18、父兄或有学问、有德行的长辈。其实国策中本身就有“先生长者，有德之称”的说法。可见“先生”之原意非真正的“教师”之意，倒是与当今“先生”的称呼更接近。看来，“先生”之本源含义在于礼貌和尊称，并非具学问者的专称。称“老师”为“先生”的记载，首见于礼记?曲礼，有“从于先生，不越礼而与人言”，其中之“先生”意为“年长、资深之传授知识者”，与教师、老师之意基本一致。But he (be) never late for work. He (work) very hard.死记硬背是一种传统的教学方式,在我国有悠久的历史。但随着素质教育的开展,死记硬背被作为一种僵化的、阻碍学生能力发展的教学方式,渐渐为人们
19、所摒弃;而另一方面,老师们又为提高学生的语文素养煞费苦心。其实,只要应用得当,“死记硬背”与提高学生素质并不矛盾。相反,它恰是提高学生语文水平的重要前提和基础。Jim (like) his father very much. They often （play） badminton（羽毛球）in front of their house, sometimes they (play) table tennis in Jims school. 语文课本中的文章都是精选的比较优秀的文章,还有不少名家名篇。如果有选择循序渐进地让学生背诵一些优秀篇目、精彩段落,对提高学生的水平会大有裨益。现在,不少语文教
20、师在分析课文时,把文章解体的支离破碎,总在文章的技巧方面下功夫。结果教师费劲,学生头疼。分析完之后,学生收效甚微,没过几天便忘的一干二净。造成这种事倍功半的尴尬局面的关键就是对文章读的不熟。常言道“书读百遍,其义自见”,如果有目的、有计划地引导学生反复阅读课文,或细读、默读、跳读,或听读、范读、轮读、分角色朗读,学生便可以在读中自然领悟文章的思想内容和写作技巧,可以在读中自然加强语感,增强语言的感受力。久而久之,这种思想内容、写作技巧和语感就会自然渗透到学生的语言意识之中,就会在写作中自觉不自觉地加以运用、创造和发展。Jim (like) to talk with his father. His father (like) to hear Jim talking about his friends and his school. On Saturday or Sunday, they often (play) on the computer. Jim (have) many computer games. But he doesnt (play) them every day. He also (work) hard at his lessons.
