11、这一点也符合新的英语教学大纲的要求。首先，用听本单元的单词录音进行导入，让学生从整体上感知下单词。然后，对重点单词进行讲解，既有对单词用法的拓展，又有对短语释义的延伸。讲解和巩固练习结合，让学生加深理解词汇用法并当堂掌握。而且，练习形式多样化，有翻译，有填空，有选择，从各个角度来对词汇关进行突破。2.annual2.annual annual annual adj./n.adj./n.每年每年的的,一年一次的一年一次的,年刊年刊,年鉴年鉴 an annual event an annual event 一年一度的活动一年一度的活动 an annual report an annual repo

37、节课是关于动词V-ing 形式的语法课，设计意图是通过当堂讲解和练习来让学生掌握该语法的考点。首先，通过让学生填表格导入新课，先让学生从形式上认识V-ing形式的一般式和完成式及其对应的被动形式。然后，逐个讲解v-ing 形式作主语，宾语，表语，定语等，并且讲练结合，当堂巩固。最后，课堂检测，既能让学生自我检测，又达到了整体上巩固语法的目的。语态时态主动形式 被动形式一般式完成式(not)doing(not)being done(not)having done(not)having been done V-ing 可作主语、宾语、表语、定语、状语和宾语补足语，但不能单独作谓语。V-ing 形式
38、表示的动作与主要动词同时发生或发生在主要动词之后，用其一般式;V-ing 形式表示的动作在主要动词之前发生，用其完成时，在具体应用中也常以一般式代替完成式。Swimming is good for health._(raise)your hat to a lady is good manners.(kill)by sharks in the sea is a common thing.RaisingBeing killed Teaching is learning.教学相长 My hobby is _(make)model planes.What worried the child most
39、was (not,allow)to visit his mother in the hospital makingnot being allowed1).动名词和不定式都可以作主语，动名词作主语表示一般或抽象的多次性行为，不定式作主语往往表示具体的或一次性的动作。如：Playing with fire is dangerous.（泛指玩火）To play with fire will be dangerous.（指一具体动作）2)V-ing形式和不定式都要有对称性;当主语是不定式时，表语也用不定式；反之，当主语是 V-ing 形式时，表语也用 V-ing 形式。To see is to bel
