应熟练掌握平行四边形的判定定理.27.(1) 80/km h ;(2)7分钟;(3)220=-S t .【解析】【分析】(1)根据函数图象中的数据可以求得汽车在前9分钟内的平均速度;(2)根据函数图象中的数据可以求得汽车在中途停了多长时间;(3)根据函数图象中的数据可以求得当16≤t ≤30时,S 与t 的函数关系式.【详解】解:(1)由图可得,汽车在前9分钟内的平均速度是:12÷9=43km/min ; (2)由图可得,汽车在中途停了:16-9=7min ,即汽车在中途停了7min ;(3)设当16≤t ≤30时,S 与t 的函数关系式是S=at+b ,把(16,12)和(30,40)代入得 16123040a b a b +=⎧⎨+=⎩, 解得220a b =⎧⎨=-⎩, 即当16≤t ≤30时,S 与t 的函数关系式是S=2t-20.【点睛】本题考查一次函数的应用,解答本题的关键是明确题意,利用一次函数的性质和数形结合的思想解答.28.(1)① 2,②证明见解析;(2)①见解析,②▱ABCD 是10阶准菱形.【解析】【分析】(1)①根据邻边长分别为2和3的平行四边形经过两次操作,即可得出所剩四边形是菱形,即可得出答案;②根据平行四边形的性质得出AE ∥BF ,进而得出AE=BF ,即可得出答案;(2)①利用3阶准菱形的定义,即可得出答案;②根据a=6b+r ,b=5r ,用r 表示出各边长,进而利用图形得出▱ABCD 是几阶准菱形.【详解】解:(1)①利用邻边长分别为2和3的平行四边形经过两次操作,所剩四边形是边长为1的菱形,故邻边长分别为2和3的平行四边形是2阶准菱形;故答案为:2;②由折叠知:∠ABE=∠FBE,AB=BF,∵四边形ABCD是平行四边形,∴AE∥BF,∴∠AEB=∠FBE,∴∠AEB=∠ABE,∴AE=AB,∴AE=BF,∴四边形ABFE是平行四边形,∴四边形ABFE是菱形;(2)①如图所示:,②答:10阶菱形,∵a=6b+r,b=5r,∴a=6×5r+r=31r;如图所示:故▱ABCD是10阶准菱形.【点睛】此题主要考查了图形的剪拼以及菱形的判定,根据已知n阶准菱形定义正确将平行四边形分割是解题关键.29.(1)A型空调和B型空调每台各需9000元、6000元;(2)共有三种采购方案,方案一:采购A型空调10台,B型空调20台,方案二:采购A型空调11台,B型空调19台,案三:采购A型空调12台,B型空调18台;(3)采购A型空调10台,B型空调20台可使总费用最低,最低费用是210000元.【解析】分析:(1)根据题意可以列出相应的方程组,从而可以解答本题;(2)根据题意可以列出相应的不等式组,从而可以求得有几种采购方案;(3)根据题意和(2)中的结果,可以解答本题.详解:(1)设A

∴2001002÷=∴修车后李师傅骑车速度是修车前的2倍.【点睛】本题考查了从图象中读取信息的数形结合的能力,需要注意分析其中的“关键点”,还要善于分析各部分图象的变化趋势.。

It is 23% of China's population.The western area is rich in mineral(矿产) and energy resources(能源) (water,coal,sun energy,and wind power). It also has large grassland,ice and snow resources waiting to be developed. It is home to many wild animals and plants,and it gives us with important medicinal resource.The Chinese leaders have decided to develop the western area. Jiang Zemin said,“Without development of the western area,how can we modernize the whole country,and how can China become an economic power?”Since 1949,when the People's Republic of China was founded,it is not the first time for China to develop its western part.

On it were test questions for history. “That’s our history paper. I’m sure of it,” said James,“ It’s in Mr. Trotter’s handwriting.” “Yes,I think so.”said Dick. “ I’ll sell the paper for $1 to our classmates.” said James. So in the three days he went round the class and sold the “test paper” to his classmates. James felt happy because he got $40. All the students were sure that these questions would be in the test paper. The questions were quite difficult so they had to work hard at preparing them.The day for the exam came. Mr. Trotter walked into the classroom. “History test,”he said and then gave out the test paper. Oh dear! It was different from the paper that James had found. None of the questions were the same. None of the students did well. James had to give all their money back to his classmates. Ever since he has never looked in teachers’rubbish bins again.43. Who wrote the test questions on the paper?A.

Then they leave the notesin obvious(明显的) places,such as on the table or no the floor in the middle of the livingroom. I don’t think I like to write notes to myself. Most of the time I lose them or forgetto look at them until it’s too late. I prefer to use an alarm clock(闹钟) to tell me what Ishould do. I have ten alarm clocks in my house. They could tell me about things. For example,if I have to make a telephone call at a certain time,I’ll set an alarm clock to go off afew minutes early and put the clock by the telephone. Or if I want to watch a certain television programme,I’ll set an alarm clock at the right time and put the clock on top ofthe TV set. I can remember almost anything if I use my clocks. However,sometimes an alarmclock goes off and I don’t know what it means. I always remember setting it,but not why Iset it. If the clock is by the telephone. I know I may have set it to tell me to call someone,but I can’t be sure. I might have set it to tell myself that somebody was to call me at acertain time.47.
