as,听说考试“模仿朗读”备考指导,(,五,),5,语,调,英语中的基本语调有：升调,(),，降调,(),，升降调,(),降升调,(),和平调,(),。其用法为：,(1),升调：主要用于一般疑问句，带有疑问语气；也可用于,祈使句，表示委婉、客气；或用于陈述句，表示疑问、不肯定,或不耐烦等。如：,Can you come to us for lunch,？,你能来和我们一起吃午饭吗？,You know her,？你认识她？,So long,！太长了！,(2),降调：主要用于陈述句、特殊疑问句、祈使句,(,表命令,),和感叹句。如：,The birds are singing in the trees.,鸟儿正在树上歌唱。,When shall I give you the book,？,我什么时候要把书,给你？Leave the book on the desk.,把书放在桌子上。,What a beautiful picture,！多美的画啊！,(3),前升后降调：主要用于：,选择疑问句。如：,Which do you prefer,tea or coffee?,你更喜欢喝哪一种，茶还是咖啡？,以状语或状语从句开头的句子。如：,In my opinion,，,he is perfectly right.,依我看，他完全正确。,计数或列举。如：,One,，,two,three and four.,一，二，三，四。,I want a pen,，,a ruler and some paper.,我需要一枝笔、一把尺子和几张纸。,注意：,and,连接的几个并列的词或短语，,and,前面的都读,升调，其后的读降调。,(4),前降后升调：主要用于带有疑问语气的反意疑问句。如：,You havent finished it,，,have you,？,你还没完成，是吗？,如果反意疑问句中的疑问成分很少，则全部用降调。如：,Its a nice day,isnt it,？天气真好，不是吗？,(5),平调：指说话声调维持在同一个高度，而无升降。,如何丰富句子的表达,大多数考生写英语作文时，往往不注意语句表达形式的多,样化，句子千篇一律，缺乏生气。这里列举一些简单可行的方,法，以帮助考生丰富句子表达，提高英文写作水平。,1,改变句子长度,初学写作的人容易堆砌简单的短句，读起来单调乏味。如,果改变句子长度，做到短句、中长句、长句兼而有之，情况就,大不一样了。如：,There is one positive result of the rising crime.This has,been,the,growth,of,neighbourhood,crime,prevention,programs.These programs really work.They teach citizens to,patrol their neighbourhoods.They teach citizens to work with the,police.They have dramatically reduced crime in cities and towns,across the country.The idea is catching on.,文段中,7,个句子都是短句，十分单调。现在我们对句子长,度做些调整：,One positive result of the rising crime rate has been the,growth of neighbourhood crime prevention programs.These,programs really work.By teaching citizens to patrol their,neighbourhoods and work with the police,they have dramatically,reduced crime in cities and towns across the country.The idea is,catching on.,修改后的这段文字，有短句和，有中长句，也有长,句，不仅避免了句子单调化，还使长句更说明问题，短句也,更显力度。,2,将若干简单句合并为一个简单句,为避免堆砌简单短句，可把原若干简单句合并成只带一个,共同主语的简单句。,(1),使用并列谓语,He put on his coat.He picked his hat and umbrella.Then he,hurried from the house.,变为：,He put on his coat,picked his hat and umbrella,and hurried,from the house.,他穿上外套，拿起帽子和雨伞就急匆匆地从家出去了。,(2),使用分语短语,Judith is alarmed by the increase in meat price.She has become,a vegetarian.,变为：,Alarmed by the increase in meat price,Judith has become a,vegetarian.,因担心肉价上涨，朱迪思已开始吃素食。,(3),使用同位语,She was the mayor of the town.She was an amiable person.She,invited the four students into her office.,变为：,The mayor of the town,an amiable person,invited the four,students to her office.,镇长是一位和蔼的人，她邀请了四名学生到她的办公室。,(4),使用短语,英语中的短语十分丰富，选择面极宽。选用适当的短语把,几个简单句合并起来，是增加句子灵活性的一条捷径。如：,The streets are icy.We could not drive the car.,变为：,Because of the icy streets,we could not drive the car.,由于路面结冰，我们不能开车。,(5),善于使用连接词,有的考生写复杂句时，动辄用,so,and,but,or,then,however,yet,等，非但达不到丰富表达方式的,目的，反而会使句子结构松,散、刻板。如：,The Mississippi River is one of the longest rivers in the world,and in spring often overflows its banks,and the lives of many,people are endangered.,and,把,3,个分句一贯到,底，既乏味又可笑。因此，应慎用上,述并列连词、副词等。如果可能，不妨多用一些表示从属关系,的连接词，如,who,which,that;because,since;after,as,before,when,whenever;if,unless;as if,等。如上例可改,为：,The Mississippi River,which is one of the longest rivers in the,world,often overflows its banks in spring,endangering the lives of,many people.,密西西比河是世界上最长的河流之一，在春季时河水经常,会泛滥，严重危及两岸人民的生活。,3,打破传统的主谓结构,主谓结构的句子写多了，偶尔用几个词或短语恰到好处地,插入主谓之间，或将主谓倒置，可以为句子表达增添几分新意。,如：,Her ability to listen is an acquired skill that attracts many,friends.,变为：,Her ability to listen,an acquired skill,attracts many friends.,她,所具备的善于聆听的特质吸引了很多朋友。,
