让学生享受“说”英语的乐趣

记得有一年接手一个五年级的班,上了几个星期的课,我和学生之间都比较熟识了,但令我奇怪的事情是学生见了我之后都是一句礼貌的“老师好”。我非常惊讶,难道已经学了两年英语的小学生连几句“Hello!Good morning!Good afternoon!”的日常打招呼的英语用语也不会吗钥另一件事情是院一次上课的时候,学生把窗都关上了,我就对着靠窗的一位同学说院“Please open the window.”

一九九七年上半年上海市高等教育自学考试基础英语试卷(英语专业)评析

九七年试卷与九六年试卷相比,题型没有什么变化,细节方面略有不同,主要体现在阅读理解第二篇的构思上。总体来说,本套试题难度不大,尤其是第一大题—Multiple choice,都是很普通的语法、用词、短语结构知识,选项一目了然,似乎比九六年的容易些。Cloze—题只有两三处不太容易吃准,如关好窗户,英语里是 fasten the window,但从上下文里看很容易搞错,填     

英语的“风、雨、雪”

刮风、下雪及下雨等自然现象如何用英语比较正确、规范地表达出来,很多同学拿不准,现归纳如下,供同学们参考。I.wind这个词只有作名词时,才会有“风”的含义。例如:There isn’t much wind today.今天风不大。A cold wind was blowing from the north.从北方刮来一股冷风。除可用much,a lot of,little,no等修饰说明风力大小外,一般情况下,wind是可数名词。如果指特殊场合下的风,wind要带定冠词the。例如:The wind blew off my hat.风吹落了我的帽子。当然blow这个词也可用来表达“刮风”这个含义。其主语可以是it,也可以是wind。例如:It’…

古小诗欣赏

一幅山间静景图——(六朝梁)吴筠《山中杂诗》山际见来烟,竹中窥落日.鸟向檐上飞,云从窗里出.从游人的视角看:大山间有烟飘出,太阳从竹缝中落下,鸟儿飞向人家的房檐,窗户里流出云雾…….这一幅山间静景图(画幅边,还有一位游人),由烟飘“来”,日“落”下,鸟“飞”檐,云“出”窗——四句动景汇成.四句景语,尤妙在句“云从窗里出”,所谓“篇终出人意表”(姜夔《白石诗说》),“收场—(齿句),即勾魂摄魂之具”(李渔《闲情偶寄·大收煞》);无此句压轴,则前三句景,皆平常寡味矣;而连成一气读,则如清人沈德潜《古诗源》评曰:“四句写景,自成一格.”
