第九讲:首字母填空(一)首字母填空的特点和中考趋势首字母填空题答题时要求既要使所填的词在语法和语义上正确,又要使其符合短文内容与情景的需要,所给出的词首字母同时起着提示和限定的作用。
它不仅考查学生在词汇、语法等方面的基础知识,还考察理解、推导、分析等综合能力。
从近几年的考题来看,短文填空题所考查的单词涉及的词性范围较广,几乎涉及到了十大词类;文中所涉及的语言知识面较宽,学生需运用已学过的词法、句法及常用词组、短语、惯用法等知识进行具体分析后再答题,有一定的难度。
文章短小、精致,字数通常在100~150之间。
短文的体裁不一,有记叙文、说明文、议论文等。
短文题材丰富,内容通俗易懂,与现代生活紧密相关,如:英国人分期付款购房;度假回来的路上买家具的小故事;食物对不同年龄段的人的不同影响;被驯化的动物可以为人们做事情等,可读性、趣味性强,符合初中生的认知特点。
(二)首字母填空的解题技巧台阶式解题法:台阶一:掌握七种句子成分与十种词性之间的对应关系。
通过对单一成分的分类练习,掌握该句子成分与何种词性相对应。
词性正确是答案正确的前提。
批注:词性和句子成分在解答首字母填空题时很重要。
如果学生可以判断出一个句子缺少了什么成分,而又知道该种句子成分由何种词性的词汇可以充当,这样可以大大缩小选择范围,也可以避免一些语法错误。
以下是详细的讲解及训练。
1) 对主语的判断1. T_______ are helpful to students.2. H_____ is more important to me than money.3. Some famous s_______ are going to give lectures in our university in August.4. F_______ is my favourite sport.5. C________ stamps is my hobby.Keys: 1. Teachers 2. Health 3. scholars 4. Fishing 5. Collecting批注:由于做篇章式样的首字母填空时会受到前后逻辑关系的影响,会加大填空难度。
② They have known the matter, haven’t they? (不能用don’t they?) 他们已经知道那事情了,是吗?四.当陈述句中只含有行为动词时,若动词加了s,就用does, 若动词为原形,就用do,动词为过去式,则用did。
例如:You cleaned your house last week, _didn’t___ __you__? 你上周打扫了你的房间,是吗?Your father plays the computer very well, __doesn’t__ ___he _? 你父亲电脑技术很好,是吗?They look so happy today, _don’t ___ _they___? 你今天看起来很高兴,是吗?五.反意疑问句的陈述部分带有little, few, never, hardly, seldom,nobody, nothing, barely, scarcely等否定意义的词时,问句部分用肯定式。
如:①She never tells a lie, does she?(不用doesn’t she?) 她从不说谎,是吗?②He was seldom late, was he?(不用wasn’t he?) 他几乎不迟到,是吗?六、反意疑问句的陈述部分为I am……时,问句部分习惯上用aren’t I?表示。
如: I am a very honest man, aren’t I? 我是个很诚实的人,是吗?七.陈述部分的主语为不定代词something, anything, nothing, everything时,问句部分的主语用it。
如:①Something is wrong with the computer, isn’t it? 电脑有问题了,是吗?②Nothing has happened to them, has it? 他们什么事也没发生,是吗?八、陈述部分的主语为不定代词somebody (someone), anybody (anyone), nobody (no one), everybody (everyone)时,问句部分的主语用he或 they,这时问句动词的数应和he或 they一致。

They can even change your life - many useful things were invented by accident.For example, at first, jeans were o 87 for workers. They were very s 88and become weak easily. But other people found they could last for a long time without breaking orgetting weaker as well. Later on, jeans became popular all over the world.When you see colorful fireworks, you probably don't think about the Chinese cook who invented them in old times by accident. He mixed together some common things from the kitchen. The m 89burnt and made a beautiful light.The invention of the Band-Aid (创可贴) was also a surprise. About 90 years ago, Earle Dickson worked at Johnson & Johnson. His wife was always accidentally cutting her fingers in the kitchen, but she couldn't bandage (包扎) herself up. Dickson decided to make something to help his wife cover her cuts. So he used a piece of gauze (纱布) and put it on some tape (胶布). Later, his boss made this into a popular product: the Band-Aid.Nowadays, microwave ovens are popular around the world. But in the b 90 , people invented the microwave for the war. American Percy Spencer found that microwaves could cook. He saw a candy in his pocket getting soft when he worked b 91 the microwaves. Spencer then did many tests to p 92 that microwaves could cook food. In 1947, the first microwave oven in the world came into being.86.g________ 87. o________ 88. s________ 89. m________ 90. b________91.b________ 92. p________[拓展]单词:创口贴包扎微波炉纱布胶布86. gifts 87. only 88. strong 89. mixture 90. beginning 91. beside 92. prove2.The earth is our home; we must take care of it. This means we should keep the land, air and water clean.To pollute m 86 to make things unfit (不合适的) and unclean to use. Pollution comes in many ways. We see it, smell it, taste it and drink it. Pollution is beginning tothreaten (威胁) our health ,or happiness and our life.Man, has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the g 87 . When land was used up or water became dirty, men moved to another place. At the beginning the problem was not so s 88 because there was plenty of clean air, land and water.There weren't so many people then and their needs were fewer. All the dirty things could be taken in by nature and soon covered over (恢复). But this is no longer true. The increase of population and the d 89 of modern industry have changed that. Man is slowly polluting his environment. By putting dirty water and chemicals into rivers and lakes, we have polluted our drinking water and k 90 the fish.Our increasing population is part of the problem. More people, more waste.Where is this all to e 91 ? Are we turning the world into a big rubbish dump, or is there any hope that we can get rid of the pollution?

Mark s 86 and helped the boy pick up these things. Since they were going the same way, he helped to carry some of his things. As they walked, Mark knew that the boy' was Bill, that he loved video games, baseball and history, that he was having a lot of t 87 with his other subjects and that he had just broken up with his girlfriend.They arrived at Bill's home first and Mark was invited in for a Coke and to watch some television. The afternoon passed h 88 with a few laughs and some small talks, then Mark went home. They continued to see each other around school, had lunch together once or twice, and then they b 89 finished middle school. They ended up in the same high school where they sometimes saw and talked with each other over the years.
