September is the time for students to go back to school! For Chinese students, most schools start on the same day. We will share summer stories with the same classmates 16 the first-year students. But in US schools, students get ready for classes a little 17 .
First of all, US schools don’t all start on the same day. Classes begin any time between August
and September. Every 18 decides when to begin their classes. If summer are too 19 , then school will usually start a little later.
Every year we usually see the same teachers and classmates, but US students have some big changes. In US high schools teachers divide 20 into different levels. Students can choose their favorite teachers and courses according to their abilities and 21 . This means that every year US students will 22 different classrooms for each class. They will meet 23 classmates and teachers. Also, students will go to school a few days early to get their 24 so that they can know the plan for their classes.
For first year students, the first day of school also means they finally get their own lockers(储
物箱). Primary school students in the US have to share closets(储物柜)with their 25 . But once students make it to junior high they finally get one.

III. 阅读理解(共15小题,每小题2分,计30分)
阅读A、B、C三篇材料,然后从各小题所给的四个选项中选出最佳选项。
A
Giving directions in different places
If you ask people of different countries “Could you tell me the way to the post office? You will get different answers.
In Japan, people use landmarks (路标) instead of street names. For example, Japanese will say to travelers,“Go straight do wn to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop. ”
In Kansas, America, there are no towns or buildings within (在……之内) miles. So instead of landmarks, people will tell you directions and d istance. For example, people will say, “Go north two miles(英里). Turn east, and then go another mile.”
People in Greece sometimes do not even try to give directions. They will often say, “Follow me.” Then he or she will take you through the streets of the city to the post office.
Sometimes if a person doesn’t know the answer to your question, he or she, like a New Yorker, might say, “Sorry, I have no idea.” But in Yucatan, Mexico, no one answers “I don’t know.” People there think “I don’t know” is not poli te. They usually give an answer, but often a wrong one. A visitor can often get lost in Yucatan!
But one thing will help you everywhere. You might not understand a person’s words, but maybe you can understand his or her body language. He or she will usually point to the correct direction. Go on in that direction and you may find the post office!
(B)26. People in Japan ________ to show the way.
A. tell you directions and distance
B. use landmarks
C. often says “Follow me.”
D. Sorry, I have no idea.
(B)27. In Kansas, America, there are towns or buildings within (在……之内) miles.

Every year, more than nine million people all over the world come to visit London.
They go to the museums and theatres; they look at interesting old buildings or have a drink in a park.
A quick and easy way to get to different places in the city is to take an underground train. The London underground is one of the best and most widely used transport networks(网状组织)in the world. The trains run all day and most of the night. You'd better not take the underground between eight o'clock and ten o'clock in the morning, or four o'clock and six o'clock in the afternoon. The trains are so crowded that you can hardly move or find a place to sit.
London's famous red buses form a big part of getting around in London. Although the London underground is the fastest and the simplest way of getting around London, the buses play their pat and are an experience you should try at least o nce. By sitting on the top deck (层) of the bus, you can get a great sightseeing (观光的) experience of London as well.
Some special visitors' buses take you to many of the interesting places in the city on one journey. It takes about one and a half hours, but you can cancel your journey and get off (and on again) at the different places you want to visit.
London taxis are called "black cabs”. Most of them are black, but some are not. You can sto p one if it has a "For Hire (供租用的) sign on it. The drivers are friendly and helpful.
In a word, London is a big and beautiful city with lots to see and to do. Welcome to London.

Four: underground train, red buses, spec ial visitors’ buses and taxis (black cabs).
43. If you go to visit London, which two kinds of transportation are you going to choose? Why? Underground trains/an underground train and red buses. Because they are quick and interesting.

Everyone has his dreams of the 46. future. But do you know what future really is? I think future is now. That is to say, w e must treasure(珍惜) every minute and second.
There is an old English 47. saying, “Gain time, gain life. ” Then what is time? Time is something that can’t be seen or touched, but we feel it passing by. Time is always with us. We often say “Time is money”, but it is 48. more valuable(valuable) than money, because when money is spend, we can earn it back. But if time is gone away, it will never return. That’s why we say time is priceless.
Grasping the present is grasping the future. As students, we should work hard in order to create a bright future of our own. We should make the best use of every hour and be the master today. We should try our 49. best (good) to do things well. And never put off what can be done today till tomorrow. Time and tide wait for no man. If you waste today, you will 50. regret(regret) tomorrow.

第十二章分式 1.分式与整式不同的是:分式的分母中含有字母,整式的分母中不含字母 对于任意一个分式,分母不能为零,分式有意义 对于任意一个分式,分母为零,分式无意义 4.分式的值为零含两层意思:分母不等于零;分子等于零。 5.平方差公式 a2-b2=(a+b)(a-b)两个数的平方差,等于这两个数的和与这两个数的差的积 6.完全平方公式a2+2ab+b2 = (a+b)2a2-2ab+b2=﹙a-b﹚2两个数的平方和,加上(或者减去)这两个数的积的2倍,等于这两个数的和(或者差)的平方 7.常见的恒等变形如x-y=-(y-x),(x-y)2=(y-x)2, (x-y)3= -(y-x)3. 8.约分:把一个分式中相同的因式约去的过程叫做约分 9.最简分式:如果一个分式中没有可约的因式,则为最简分式 10.通分:把几个异分母的分式分别化成与原来的分式相等的同分母的分式,叫做分式的通分 11.通分和约分都是依据分式的基本性质进行变形,其共同点是保持分式的值不变. 12分式的基本性质:分式的分子和分母乘(或除以)同一个不等于0的整式,分式值不变。 通分的关键:确定几个分式的最简公分母。通常取各分母系数的最小公倍数与字母因式的最高次幂的积作公分母,这样的公分母叫做最简公分母。求最简公分母时,首先要因式分解,将所有的表达式都化成积的形式,然后,再定最简公分母. 解分式方程的一般步骤:(1)去分母,方程两边同乘各分母的最简公分母,将分式方程转化为整式方程; (2)解整式方程;(3)验根:可把整式方程的根分别代入最简公分母,如果使最简公分母为0,那么这个根叫分式方程的增根,必须舍去;如果使最简公分母不为0,那么这个根是原分式方程的根;(4)写出方程的解. 15、用分式方程解应用题常见的等量关系 一.工程问题 1.工作效率×工作时间=工作总量工作总量÷工作效率=工作时间 工作总量÷工作时间=工作效率 设工作总量为“1”的公式:1÷单独完成的工作时间=工作效率;1÷工作效率=单独完成的工作时间。 2.完成某项任务的各工作量的和=总工作量=1 二.营销问题 1.商品总利润=商品总售价一商品总成本价= 商品单件利润×销售量 2.商品单件利润=商品单件售价一商品单件成本价 3.商品利润率=商品总利润/商品总成本价×100%=商品单件利润/商品单件成本价×100% 4.商品销售额=商品单价×商品销售量 5、折扣=实际售价÷原售价×100%(折扣<1) 三.行程问题 1.路程=速度×时间,速度=路程/ 时间 2.在航行问题中,其中数量关系是(同样适用于航空):顺水速度=静水速度+水流速度 逆水速度=静水速度-水流速度 增长率问题原来量×(1 增长率)=现在量 第十三章全等三角形 1、能够完全重合的两个三角形叫做全等三角形 2、全等三角形的性质: (1)全等三角形的对应角相等,对应边相等. (2)全等三角形中的对应线段相等.即对应的角平分线,对应的中线,对应的高线相等。
