1．根据材料内容，选择正确答案。
C
Prana was a beautiful dog, whose name means “breath of life”. Although he died several years ago, I can still remember the days we spent together and what he has taught me about love.
I have two apple trees in the garden. Prana loved apples. When he went outside, he'd catch an apple and take it into the house to eat later. The apples had been on the ground and were often dirty so I wasn't always happy that Prana had brought them into the house.
It was an autumn day in America, but it was very cold. A big snow fell and we had not done anything for its coming. On that special day, Prana went outside and I watched him through the window. I noticed that he was madly digging（挖） holes and bringing the apples to the ground so they could be seen above the snow. I did not know why he was doing this. He seemed to want to do something special.
When I called him back, he had his usual one apple in his mouth. About five minutes later, I looked outside. The garden was completely covered with birds. Prana had dug up all those apples for his bird friends to eat. He knew that they wouldn't have stored enough food for the coming winter!

One Monday morning, I was waiting at the bus stop in Harvard Square. It was very cold, about -8℃.

"What would go wrong with my husband's operation （手术）?" "Will I get to him before it starts?"
Among the others at the bus stop was a woman who was about 50 years old. She wore an old hat, an old pair of boots and a dark coat, but she had no gloves （手套）. Another woman who looked younger came to the older woman and said, "Your hands must be very cold. You will get frostbite （生冻疮） in this weather if you don't wear gloves." With these words, she dropped her heavy bag to the ground. After a while, she took out a pair of purple gloves from her bag, took the older woman's hands and gently placed a glove on each hand. "Thank you. You're so kind." The old woman said again and again.
I was deeply moved （感动） by this act of kindness. A moment ago, I was feeling sorry for myself, but now I felt hopeful and optimistic （乐观）. I thought in this world there were still many people in trouble who were in great need of our help.

Long, long ago people made fires from lightning （闪电）. But they had to keep the fire burning, for they couldn't start it again if there was no lightning. Later, they found out hitting two pieces of stone together could make a spark（火花）. The spark could fire dry leaves. In this way they could make a fire again if it went out. Then people also learned to make a fire by rubbing （摩擦）. They made a hole in a piece of wood and put a smaller stick into the hole. They turned the stick again and again. After a few minutes they got fire.
Years went by, people learned other ways to make a fire. Sometimes they used the heat from the Sun. They held a piece of glass in the right way and made a piece of paper on fire.
About two centuries ago, people began to make matches. Matches brought people a quick and easy way to make fires. Today matches are still being used, but people have more new ways to make fires.

A. No, he didn’t (×) B. Yes, he did (√) 例--- Don’t you usually come to school by bike?-- _______. But I sometimes walk. A. No, I don’t (×) B. Yes, I do (√) [析] 习惯上英语中的yes意为“是的”，no意为“不”，但在“前否后肯”的反意疑问句或否定疑 问句中，yes意为“不”，no意为“是的”。 20.---- Excuse me, is the supermarket far from here?---- No，it's about _______. A. 7 minutes walk B. 7 minute walk C. 7 minutes' walk D. 7 minute's walk 答案为C。本题考查名词所有格用法。当名词的复数以-s结尾时，则只需要加“'”即可，则“7分钟的距离”为“7 minutes' walk”。 21. You can not imagine how much I ______ on this dress. Is it beautiful? A. paid B. took C. cost D. spent [剖析] 答案为D。本题考察四个表“花费”的动词辨析。主语为人，且和介词on搭配的动词是spend。 22. ---- Do you know _____ university student who is talking with Joe?---- Yes， she，s my cousin, Kate. A. a B. an C. the D. / [剖析] 答案为C。university虽然以元音字母u开头，但其前若使用不定冠词时，则要用 a.不过此题中不能使用不定冠词，而是特指和Joe说话的那个大学生，故要选the。

大家知道，现在的中考英语试题总体不难，只要不放弃英语学习的学生都可以考及格以上，但欲考接近满分却并非易事。因为为了适当拉开学生距离，命题老师往往也会出一两个所谓的压轴题，以把那些真正的英语尖子生选拔出来。有时候我们学生与重点高中失之交臂，就是失分在下面我精选的难题上。 ( ) 1. ________ it is today! A. What fine weather B. What a fine weather C. How a fine weather D. How fine a weather 解析：选A. 此题容易误选B. weather是不可数名词，前面不能有不定冠词。英语中经常考查的不可数名词有work, news, adivice, information等。 ( ) 2. Which is the way to the __________? A. shoe factory B. shoes factory C. shoe’s factory D. shoes’ factory 解析：选A. 此题极易误选B, C, D. 英语中名词单数可以修饰名词，如：an apple tree →two apple trees. 但注意a man teacher→two men teachers。 ( ) 3. This class ________ now. Miss Gao teaches them。 A. are studying B. is studying C. be studying D. studying 解析：选A. 此题容易误选B. class, family, team等单词如果表示整体谓语就用单数，表示个体就用复数，从语境及其后面的代词them可以看出，class表示个体，故选择A。( ) 4. We will have a _________ holiday after the exam。 A. two month B. two-month C. two month’s D. two-months 解析：选择B 此题容易误选C, D. 在英语中数词中间用连字符号加名词单数，构成符合名词，在句中只能作定语，如果选择C, 需要把逗号放s后面。 ( ) 5. There is no enough ________ on the corner to put the table。 A. place B. room C. floor D. ground 解析：选B. 此题最容易误选A.。room在句中是空间而非房间。句意：角落里没有摆桌子的空间了。 ( ) 6. We can have _____ blue sky if we create _____ less polluted world。(苏州2010) A. a; a B. a; the C. the; a D. the; the 解析：选A. 此题容易误选C, D. 根据句意：如果我们创造一个没有污染的世界，那么我们就用一个蓝色的天空。 ( ) 7. —Are you ______ American or English? —English.. We are working in Wuhu. (芜湖10) A. a B. \ C. the D. an 解析：选B 此题容易误选D. 句中American是形容词而非名词，如果句中改为Are you __________ or an English man? 就选择D。 ( ) 8. You like playing basketball, and he likes running, _______? A. don’t you B. doesn’t he C. do you D. does he 解析：选择B. 此题容易误选A. 其实不是对前面的句中进行反问，而是对he likes running 进行反问。 ( ) 9. —Why not take ____umbrella with the sign “Made in China”？It is _____ useful umbrella? —What _______ good advice it is! A. an; an; a B. an; a; \ C. a; an; a D. \; an; a 解析：选B. 大多数学生容易做错此题。记住an用在元音音素前而不是元音字母前，记住了这一点就知道了an umbrella 和a useful umbrella. 在最后一句中advice是不可数名词，前面不能接不定冠词。故选择B ( ) 10. — When shall we meet again next week?

一、中考初中化学科普阅读题 1．都市中的光化学烟雾在温暖、干燥而且阳光充足的日子特别严重。它的原级污染物，主要是一氧化氮(NO）。一氧化氮乃是空气中的氮气和氧气，在汽车引擎的高温下，相互反应而生成。事实上，这个一氧化氮的生成过程，与闪电时产生一氧化氮的过程相同。其他光化学烟雾的原级污染物，包括汽油挥发所产生的碳氢化合物和一氧化碳(CO）。 一氧化氮是一种无色的气体，但是当它从汽车废气排入空气后，与空气中的氧气反应，产生红棕色的二氧化氮。二氧化氮（NO2）可以与空气中的水分子起作用，而生成硝酸(HNO3）和亚硝酸(HNO2）。这个反应同时也会帮助空气中的水汽凝聚。但是由于硝酸及亚硝酸的酸性极强，如果吸入含有这种液体微滴的空气，将对人体造成相当程度的伤害。 依据文章内容，回答下列问题： （1）NO的物理性质______________________________。 （2）NO和NO2的化学性质不同的原因____________________。 （3）用化学方程式表示产生NO的过程____________________。 （4）NO2和H2O反应的化学方程式是____________________。 （5）你认为应该如何防止光化学污染____________________。（写一条即可） 【答案】无色气体分子构成不同 N2+ O22NO 2NO2+ H2O = HNO3+ HNO2减 少汽车尾气的排放 【解析】 【分析】 【详解】 （1）物理性质是不需要发生化学变化就能表现出来的性质，通常包括颜色、状态、气味、溶解性等。 （2）决定物质的性质的是组成和结构，NO和NO2的化学性质不同的原因分子的构成不同。 （3）产生NO的过程化学方程式：N2+ O22NO （4）NO2和H2O反应的化学方程式是2NO2+ H2O = HNO3+ HNO2 （5）防止光化学污染的措施很多，如：少开私家车，使用清洁燃料，减少污染物的排放等 2．伶仃洋上“作画”，大海深处“穿针” 港珠澳大桥是连接香港、珠海和澳门的特大型桥梁隧道结合工程，横跨珠江口伶仃洋海域。它的构造图如下图所示，若行进在桥上，可一览沿途多种类型的风景。而它也是伶仃洋上最美的一处风景。
