April 1st, or April Fool's Day is the day when we play jokes on people. Do you have it in your country?April Fool's Day started in the sixteenth century in Europe. Before that time, New Year's Day was celebrated on April 1st.If they were teased, they were called fools.Nowadays we play jokes on people on April 1st.For example, someone might put salt in the sugar bottle so another person could put it in his coffee “by accident”．Or someone might change the time on another person's alarm clock so that person would unknowingly wake up earlier or later than planned. Or maybe a person would tell a lie to make someone else shocked.After we play the trick, we say “April Fool”. Then the poor person realized he was fooled. It is generally done in the spirit of fun and doesn't cause any real harm (伤害) to anyone. Do you have any great jokes to play on anyone today? Try it out. Just don't forget to say “April Fool” when the other person begins looking a little confused.26．Before the sixteenth century, New Year's Day was ________.A．April 1st B．January 1stC．October 1st D．February 1st27．Which of the following situations doesn't make you “April Fool”？A．Someone might put salt in the sugar bottle, then you could put it in your coffee “by accident”．B．A man might take your bag by mistake, then he could say sorry to you.C．Someone might change the time on your alarm clock, then you would unknowingly wake up earlier or later than planned.D．A person would tell a lie to make someone else shocked.28．Sometimes people lie to shock someone on ________.A．New Year's Day B．Christmas DayC．April Fool's Day D．Thanksgiving Day29．In the 2nd paragraph, the closest meaning of the underlined word “teased” is ________ in English.A．hit B．criticizedC．laughed at D．shocked30．What should be the right attitude (态度) towards “April Fool”？A．It is generally done in the spirit of fun and doesn't cause any real harm to anyone.B．It is done for the real fools.C．We needn't say “April Fool” when we play jokes on people on April 1st.D．Don't play jokes on people.Valentine's Day is a very old holiday. It goes back to the times of Ancient Rome (古罗马)．One of the characters we often see on Valentine's Day is Cupid. He was the son of Venus, the goddess of love. He shoots people with arrows (箭) of love. When a man and a woman are hit by his arrows, they will fall in love.Today people celebrate Valentine's Day on February 14.If a man and a woman are in love, they will give each other gifts. The most popular gifts are flowers (especially roses) and chocolates. Couples may also go to a restaurant for a very nice dinner or plan something else romantic.In the United States, Valentine's Day is not just for lovers. Children make special Valentine's cards for their classmates. Families and friends may give candy or other small gifts to each other. It can be a fun day.31．Who is Cupid?A．The arrow of love.B．The goddess of love.C．The son of the goddess of love.D．The first person to celebrate Valentine's Day.32．When a man and a woman are hit by Cupid's arrows, they will ________.A．fall in love B．get gifts from GodC．hate each other D．fight each other33．What are the most popular gifts on Valentine's Day?A．Roses and chocolates.

They put up their tents(帐篷)and then rode off to a forest to see how the trees were growing.In the afternoon when they were about ten kilometers from their camp(营地)，it started to snow. More and more snow fell. Soon Bob could hardly see his hand before his face. He could not find the road! Bob knew there were two roads. One road went to the camp，and the other went to his house. But all was white now. Everything was the same. How could he take his friends back to the camp?Bob had an idea. The horses! Let the horses take them back! But what would happen if the horses took the road to his house? That would be a trip(行程) of thirty-five kilometers in such cold weather!It was getting late. They rode on and on.

=++-的图象经过二三四象限，不经过第一象限．故答案为：一．【点评】本题考查的是一次函数的图象与系数的关系，熟知一次函数(0)y kx b k =+≠中，当0k <，0b <时函数的图象在二、三、四象限是解答此题的关键． 13．（3分）已知二次函数23(1)1y x m x =-+-+，当12m x +>时，y 随x 的增大而减小，则m 的取值范围是 2m - ．【分析】根据函数解析式可知，开口方向向下，在对称轴的右侧y 随x 的增大而减小，在对称轴的左侧，y 随x 的增大而增大． 【解答】解：函数的对称轴为112(3)6m m x --=-=⨯-，又二次函数开口向下，∴在对称轴的右侧y 随x 的增大而减小，当12m x +>时，y 随x 的增大而减小， ∴1162m m -+．解得2m -， 故答案为：2m -．【点评】本题考查了二次函数的性质，能根据解析式推知函数图象是解题的关键，另外要能准确判断出函数的对称轴．14．（3分）如图，抛物线2(2)3(0)y a x a =++<与y 轴正半轴交于点A ，过点A 作//AB x 轴交抛物线于点B ，抛物线的对称轴交抛物线于点M 、交x 轴于点M ，连结MA 、MB 、MA 、NB ，则四边形ANBM 的面积为 6 ．【分析】根据二次函数的性质得到抛物线2(2)3y a x =++的顶点坐标为(2,3)-，抛物线的对称轴为直线2x =-，利用抛物线的对称性得到4AB =，然后根据三角形面积公式计算即可． 【解答】解：抛物线2(2)3y a x =++的顶点坐标为(2,3)-，抛物线的对称轴为直线2x =-， //AB x 轴，224AB ∴=⨯=，∴四边形ANBM 的面积1143622AB MN =⨯⨯=⨯⨯=． 故答案为6．【点评】本题考查了抛物线与x 轴的交点：把求二次函数2(y ax bx c a =++，b ，c 是常数，0)a ≠与x 轴的交点坐标问题转化为解关于x 的一元二次方程．也考查了二次函数的性质．15．（3分）设1(2,)A y -，2(1,)B y ，3(2,)C y 是抛物线222y x x =--+上的三点，则1y ，2y ，3y 的大小关系为 123y y y >> ．【分析】根据二次函数的性质得到抛物线2222(1)3y x x x =--+=-++，开口向下，对称轴为直线1x =，然后根据三个点离对称轴的远近判断函数值的大小．【解答】解：抛物线2222(1)3y x x x =--+=-++，开口向下，对称轴为直线1x =-， 而3(2,)C y 离直线1x =-的距离最远，1(2,)A y -点离直线1x =-最近， 123y y y ∴>>．故答案为123y y y >>．【点评】本题考查了二次函数图象上点的坐标特征：二次函数图象上点的坐标满足其解析式．也考查了二次函数的性质． 三、解答题 16．解方程： （1）2310x x ++=（2）2(3)4(3)0x x x -+-=．【分析】（1）求出24b ac -的值，代入公式求出即可． （2）先分解因式，即可得出两个一元一次方程，求出即可． 【解答】解：（1）2310x x ++= 22434115b ac -=-⨯⨯=，∴12x =；（2）分解因式得：(3)(34)0x x x --+=， 340x x -+=，30x -=， 123,35x x ==．【点评】本题考查了解一元二次方程的应用，主要考查学生的计算能力．17．已知二次函数2241y x x =--+，先用配方法转化成2()y a x h k =-+，再写出函数的顶点坐标、对称轴以及描述该函数的增减性．【分析】利用配方法整理成顶点式，然后写出顶点坐标和对称轴，由对称轴和抛物线开口方向写出函数的单调性．【解答】解：222412(1)3y x x x =--+=-++．∴该函数的图象的顶点坐标是(1,3)-，对称轴为1x =-，抛物线开口方向向下， ∴当1x <-时，y 随x 的增大而增大，当1x >-时，y 随x 的增大而减小．【点评】本题考查了二次函数的三种形式，二次函数的性质，二次函数图象与x 轴的交点问题，熟练掌握配方法的操作整理成顶点式形式求出顶点坐标和对称轴更加简便． 18．已知关于x 的一元二次方程22(21)10x k x k k --++-=有实数根． （1）求k 的取值范围；（2）若此方程的两实数根1x ，2x 满足221211x x +=，求k 的值． 【分析】（1）根据方程有实数根得出△22[(21)]41(1)850k k k k =---⨯⨯+-=-+，解之可得．（2）利用根与系数的关系可用k 表示出12x x +和12x x 的值，根据条件可得到关于k 的方程，可求得k 的值，注意利用根的判别式进行取舍．【解答】解：（1）关于x 的一元二次方程22(21)10x k x k k --++-=有实数根，∴△0，即22[(21)]41(1)850k k k k ---⨯⨯+-=-+，解得58k ．（2）由根与系数的关系可得1221x x k +=-，2121x x k k =+-，222222121212()2(21)2(1)263x x x x x x k k k k k ∴+=+-=--+-=-+，221211x x +=，226311k k ∴-+=，解得4k =，或1k =-， 58k ， 4k ∴=（舍去）， 1k ∴=-．【点评】此题主要考查了根与系数的关系，将根与系数的关系与代数式变形相结合解题是一种经常使用的解题方法．19．要修一个圆形喷水池，在池中心竖直安装一根水管，水管的顶端安一个喷水头，使喷出的抛物线形水柱在与池中心的水平距离为1m 处达到最高，高度为3m ，水柱落地处离池中心3m ，水管应多长？【分析】以池中心为原点，竖直安装的水管为y 轴，与水管垂直的为x 轴建立直角坐标系，设抛物线的解析式为2(1)3(03)y a x x =-+，将(3,0)代入求得a 值，则0x =时得的y 值即为水管的长．【解答】解：以池中心为原点，竖直安装的水管为y 轴，与水管垂直的为x 轴建立直角坐标系．由于在距池中心的水平距离为1m 时达到最高，高度为3m ， 则设抛物线的解析式为：2(1)3(03)y a x x =-+， 代入(3,0)求得：34a =-．将a 值代入得到抛物线的解析式为： 23(1)3(03)4y x x =--+，令0x =，则92.254y ==． 故水管长为2.25m ．【点评】本题考查了二次函数在实际生活中的运用，重点是二次函数解析式的求法，利用顶点式求出解析式是解题关键．20．若二次函数2(0)y ax bx c a =++≠中，函数值y 与自变量x 的部分对应值如表：（1）求该二次函数的表达式；（2）当4y 时，求自变量x 的取值范围．【分析】（1）根据表中点的坐标得出函数的对称轴，设二次函数的表达式是21()2y a x k =++，把点的坐标代入求出即可；（2）求出4y =时对应的x 的值，再根据二次函数的性质得出即可． 【解答】解：（1）根据表中可知：点(1,2)--和点(0,2)-关于对称轴对称， 即对称轴是直线12x =-，设二次函数的表达式是21()2y a x k =++，把点(2,0)-和点(0,2)-代入得：221(2)021(0)22a k a k ⎧-++=⎪⎪⎨⎪++=-⎪⎩，解得：1a =，94k =-，2219()224y x x x =+-=+-，所以该二次函数的表达式是22y x x =+-；（2）当4y =时，224y x x =+-=， 解得：3x =-或2，所以当4y 时，自变量x 的取值范围是3x -或2x ．【点评】本题考查了二次函数的图象和性质，用待定系数法求二次函数的解析式等知识点，能求出二次函数的解析式是解此题的关键．21．如图，在ABC ∆中，90B ∠=︒，5AB cm =，7BC cm =，点P 从点A 开始沿AB 边向点B 以1/cm s 的速度移动，同时点Q 从点B 开始沿BC 这向点C 以2/cm s 的速度移动．当一个点到达终点时另一点也随之停止运动，运动时间为x 秒(0)x > （1）求几秒后，PQ 的长度等于5cm ；（2）运动过程中，PQB ∆的面积能否等于28cm ？说明理由．【分析】（1）根据5PQ =，利用勾股定理222BP BQ PQ +=，求出即可； （2）通过判定得到的方程的根的判别式即可判定能否达到28cm ． 【解答】解：（1）当5PQ =时，在Rt PBQ ∆中，222BP BQ PQ +=，222(5)(2)5x x ∴-+=， 25100x x -=， (510)0x x -=，10x =（舍去），22x =， ∴当2x =时，PQ 的长度等于5cm ．（2）设经过x 秒以后PBQ ∆面积为8， 1(5)282x x ⨯-⨯= 整理得：2580x x -+= △253270=-=-<PQB ∴∆的面积不能等于28cm ．【点评】此题主要考查了一元二次方程的应用，解题的关键是找到等量关系，列出方程并解答．22．某商场今年年初以每件25元的进价购进一批商品．当商品售价为40元时，三月份销售128件，四、五月份该商品的销售量持续走高，在售价不变的前提下，五月份的销量达到200件．假设四、五两个月销售量的月平均增长率不变 （1）求四、五两个月销售量的月平均增长率；（2）从六月起，商场采用降价促销方式回馈顾客，经调查发现，该商品每降1元，销售量增加5件，当商品降价多少元时，商场可获利2250元？【分析】（1）由题意可得，3月份的销售量为：128件；设四、五月份销售量平均增长率为x ，则4月份的销售量为：128(1)x +；5月份的销售量为：128(1)(1)x x ++，又知5月份的销售量为：200件，由此等量关系列出方程求出x 的值，即求出了平均增长率； （2）利用销量⨯每件商品的利润2250=求出即可．【解答】解：（1）设四、五月份销售量平均增长率为x ，则2128(1)200x += 解得10.2525%x ==， 2.25x =-（舍去） 所以四、五月份销售量平均增长率为25%；（2）设商品降价m 元，则(4025)(2005)2250m m --+= 解得15m =，230m =-（舍去）所以商品降价5元时，商场获利2250元．【点评】此题主要考查了一元二次方程的应用，本题的关键在于理解题意，找到等量关系准确的列出方程是解决问题的关键．23．如图所示，一元二次方程2230x x +-=的两根1x ，212()x x x <是抛物线2y ax bx c =++与x 轴的两个交点C ，B 的横坐标，且此抛物线过点(3,6)A （1）求此抛物线的函数解析式；（2）设此抛物线的顶点为P ，对称轴与线段AC 交于点Q ，求点P ，Q 的坐标． （3）在x 轴上是否存在以动点M ，使MQ MA +有最小值，若存在求出点M 的坐标和最小值，若不存在，请说明理由．【分析】（1）求出一元二次方程2230x x +-=的两个根就可以求出抛物线2y ax bx c =++与x 轴的两个交点C ，B 的坐标，再有待定系数法就可以直接求出抛物线的解析式．（2）由（1）的解析式化为顶点式就可以求出抛物线的顶点坐标和对称轴，再根据A 、C 的坐标就可以求出直线的解析式，再将顶点坐标的横坐标代入解析式就可以求出交点坐标． （3）根据（2）求得的P 、Q 的坐标得知P 、Q 关于x 轴对称，由轴对称的性质连接AP ，与x 轴的交点即为所求点M ，求出P 、Q 的解析式就可以求出M 的坐标，由勾股定理就可以求出MQ MA +的最小值．【解答】解（1）解方程2230x x +-=，得13x =-，21x =，∴交点(3,0)C -，(1,0)B ，设解析式为(3)(1)y a x x =+-， 点(3,6)A 在抛物线上，所以解得12a =， ∴21322y x x =+-；（2）由22131(1)2222y x x x =+-=+-， 可知顶点P 的坐标(1,2)--，对称轴为1x =-． 设AC 线段的解析式为y kx b =+， (3,6)A ，(3,0)C -在直线上， ∴3630k b k b +=⎧⎨-+=⎩，解得1k =，3b =， 3y x ∴=+．将1x =-代入得2y =，所以Q 点的坐标为(1,2)-；（3）存在．理由如下： 点P 、Q 关于x 轴对称，∴连接AP ，与x 轴的交点即为所求点M ，连接QM ，QM PM ∴=，QM AM PM AM ∴+=+．设直线AP 的解析式为y ax k =+． 同上理可得2a =，0k =，2y x ∴=；令0y =，则0x =，所以点M 的坐标为(0,0)．过点A 向PQ 做垂线，垂足为H ，则4AH =，8PH =， 在RT AHP ∆中，2245PA AH PH =+=，5MQ MA ∴+=【点评】本题考查了待定系数法求抛物线的解析式和直线的解析式，根与系数的关系，二次函数的性质，勾股定理的运用及轴对称最短路线问题．。

Some students had more specific suggestions. Li llian Li, for example, said the best way to learn new words was by reading English maga zines. She said thatmemorizing the words of pop songs also helped a little. When we asked about studying g rammar, she said, “I never study grammar. It’s too boring.”Wei Ming feels differently. He’s been learning English for six years and really loves it. He thinks studying grammar is a great way to learn a language. He also thinks that watch ing English moviesisn’t a bad way because he can watch the actors say the words. Sometimes, however, he findswatching movies frustrating because the people speak too quickly.Liu Chang said that joining the English club at school was the best way to improve her E nglish. Students get lots of practice and they also have fun. She added that having conver sations with friends was not helpful at all. “We get excited about something and then end up speaking in Chinese,” she said.阅读文章，判断下列句子是否正确，正确的写“T”，错误的写“F”（10分，平均每小题2分）( ) 1. Lilian Li thought the best way to learn new words was by memorizing them.

April is the most beautiful time to go there and it’s a great time to see the sights and learn about the culture.◎Have your eyes ever rested upon the pyramids in Egypt? Visiting Egypt is an adventure. Please pay attention to my advice and go only in December or January because at any other time in the year it is just too hot, dry and dusty. Enjoy!◎Barcelona, Spa in is my favorite city. It’s an expensive place to go, but it is really worth the visit. If you go in summer, you won’t regret it.◎Lisbon at sunset is a wonderful sight to see! The colors of the sunlight are very beautiful! Saint Jorge’s Castle in the city is a fascinating place to look at.◎Florence, Italy is a city that is hard to forget. Rome is also pretty cool and the food is excellent, but I always feel worried about being pick-pocketed (扒窃) while I am there.◎Oslo, Norway. I went there when I was about 11 years old and my best friend’s family was originally from there. It was really beautiful and what I remember most is that everyone I saw there had blonde hair.1. If you go to Japan in April, you can ______.A. feel too dry and dangerousB. visit the beautiful Saint Jorge’s CastleC. enjoy the beautiful cherry blossom2.

People in Oslo are really handsome.C. The writer thinks there are always many thieves in Rome.【第三篇】Halloween is a strange holiday. It started several centuries ago in Europe . It began as "Hallow Evening" which means "holy night". At that time November 1st was called "All Saints' Day" ( 万圣日) and people honored ( 尊敬) all the saints who didnot have their own special day. People believed that all the spirits of dead people were active on the night of October 31st . So people would play all sorts of tricks on each other .Black is one of the traditional Halloween colors, probably because Halloween festivals and traditions took place at night. Pumpkins are a symbol of Halloween, so orange has become the other traditional Halloween color. Making lanterns out of pumpkins is a Halloween custom , Halloween is great fun for children. They dress up as ghosts or witches . Small children go "Trick –or -- Treating". They wear costumes, knock on doors, and shout ,"Trick or Treat!" People almost always choose to give them candy as a treat , instead of choosing to receive a trick from the children. Adults sometimes "trick or treat" their friends,too. Usually the "treat" is a glass of wine or some small gifts.根据短文内容，完成下列句子，每空一词。

I was only 6 years old at that time. It was a very big room. I sat at the desk near the window, but I couldn’t see anything because the window was too high. There was a big map of the world on the wall and an old blackboard. I don’t think I was worried or afraid at that time. There was another little boy next to me. He sat there and kept silent at first. Then he began to cry, because he didn’t want to stay there.More and more students came in, but the boy didn’t stop crying. “Mom, I want to go home.” He cried again and again. Later, the teacher came in. She went to the little boy, and said something to him. I couldn’t hear what she said. Soon the boy stopped crying and beg an to smile.
