你与你的同班同学相处得好吗?（ ）you（ ）（ ）your classmates

①要学会在合作中竞争。在合作中竞争，就要尊重竞争对手，向竞争对手学习。②合作的过程是互帮互学，互相提高的过程。同学之间的共同点为我们的合作铺平道路，不同点则使我们在竞争中互相启发、各显神通、取长补短、携手共进。（说明：学生的答案，言之有理，即可酌情给分）

解题思路：由题意可知：要求至少再过几天，他们三人中有两人会在图书馆相遇，先分别求出4和6，4和10，6和10的最小公倍数，然后比较即可得出．

4=2×2，6=2×3，10=2×5，
所以4和6的最小公倍数是2×2×3=12；
4和10的最小公倍数是2×2×5=20；
6和10的最小公倍数是2×3×5=30；
因为12＜20＜30；
所以至少要经过12天，他们三人中有两人会在图书馆相遇；
答：至少要经过12天，他们三人中有两人会在图书馆相遇．

点评：
本题考点： 求几个数的最小公倍数的方法．

考点点评： 此题主要考查求两个数最小公倍数的方法：两个数的公有质因数与每个数独有质因数的连乘积是最小公倍数；数字大的可以用短除解答．

解题思路：设小文的步行速度为v，求出小莉骑自行车的速度；又知道从家到校的时间相同为5min，求出两人走的路程；根据题意（小莉比小文多走720m）列方程求解．

设小文的步行速度为v，则小莉骑自行车的速度为3v，
∵v=[s/t]，
∴小文走的路程：
s₁=vt，
小莉走的路程：
s₂=3vt，
由题意知，小莉比小文多走720m，
即：s₂-s₁=3vt-vt=720m，
∴v=[720m/2t]=[720m/2×5×60s]=1.2m/s．
故答案为：1.2．

点评：
本题考点： 速度公式及其应用．

考点点评： 本题也是数学上的追及问题，运动时间相同是隐含条件，利用好两人走的路程关系列方程是关键．

第一个 Hi ! welcome to our class ! My name is Linda . There are 70 students in our class . You will be very happy in here . Our Englishi teacher is Mr.Zhang ,a very handsome man ,he is 32 and his class is interesting ,i like his class . My favorite subject is math ,our math teacher is a 47 years old woman ,she is strict ,but we love she very mach , i think you will love her ,too .The Chinese is a beatuiful girl ,she is so living and active , but i don't like her . 第二个 Dady ,this is my classmate Kity , Kity is very good and she is a Chinese K ity ,this is my Dad ,he is a doctor .其他的要你自己想了.

上课认真、下课复习、做作业不马虎、
最重要要把学习当做一种乐趣、不要当成是一种
学习本身在于快乐、心里开朗、对学习也是一种帮助哦
别给自己太多压力、尽力就好、无论考多少、那都是自己努力得来的
加油!

这个问题,首先要想到逆向思考,考虑没有同年同月同日的概率,然后用1减.再看没有的概率,总的情况当然是730的40次方,每个人都有730次可能（别告诉我有闰年）,分步考虑,40人,所以是这些.没有重生日的,那么这40人的生日必然是占据了这730天中的40天,而且每个人在这40天中占哪一天都可以,因此是A730 40（730是下标,40是上标）一除,一减 就OK了 数太大了好像.

45+45x2/5=63人

750+600=1350m
750-600=150m

Are you good with your classmates

看,我们班的同学,可真有意思!说他们调皮吧,却又调皮得离谱!瞧,昨天就出了件震天撼地的大事!那个胖乎乎、黑黑的波波,差点把我们学校四年级的一个学生给“掐死”了,幸亏老师及时赶到,不然,后果不堪设想.最后,在老师的细心教导下,他开始觉悟了,表示今后一定痛改前非,同时,向那位四年级的学生主动承认了错误.喏,那个风度翩翩、神采奕奕的胡君赢走过来了.瞧他那副笑眯眯的脸蛋,就知道老师又表扬他了,过去一问,可不是,原来他的一篇作文在绍兴县报上发表了,怪不得那么高兴呢!告诉你们吧,他可是我们班的“第一人”呢!我们班的同学时时在努力学习,为的是“击败他”,可是,结果总是胡君赢反胜他们!瞧,我们班的“大书法家”宋巨梁又在施展他的才华了呢!那一本正经的样子,在纸上一笔一画地写着,怪不得有“大书法家”之称呢!他的作品要是给你看到,一定让你忘不了.正因为他,我们班很多同学都拜他为师了呢!当然,我们班的“人才”是数不胜数啊!那风趣幽默的马军总是逗得大家捧腹大笑,那神采飞扬得盼飞,在球场上是无人可挡,那“百灵鸟”王露萍总会让大家一饱耳福,那……,总之,我们班确实是个“人才”倍出的大家庭.要是你来我们班,准能偿遍“酸、甜、苦、辣、喜、怒、哀、乐”.

Hi Jack,
How have you been? I'm very well over here. I'm writing to you today to tell you about my new life as a senior high school student.
As you know, this is a fresh new start for us. Many people say that senior high school years are the most difficult times of a student's life. We have to work hard and keep fit to ensure that we can withstand the pressure of the college entrance examinations. As for me, I have adjusted myself well to this new life. I have made so many friends during this short period. Together, we will aspire each other to work hard.
But I must mention also that I do miss our old teachers and classmates. Having spent three years with them, we have developed deep feelings. They have been with me through all the difficulties in life. I am grateful to my teachers for their assistance and guidance. Without them, I won't have made it here today.
As for the future, I must work harder than I used to be. Three years later, we will be sitting for the college entrance examination. I don't have much time to waste. Therefore, I must make sure that I pay attention in class, be consistent in my work and try and improve myself. I hope you will do the same too! And I hope that we will both get into the university that we have been dreaming of.
Yours sincerely,
Tom

Dear Mei,I have heard some of your classmates suggested that you should represent your class and participate in the Debate Competition in English.This is a great honor!Everybody knows that you always get the highest grade in English exams,and you speak English fluently as well.Mei,don't be shy!We trust your abilities,and that is why you are the first person coming into our minds when we think of the person who should participate in the debate.Step forward and let your excellent skills shine!Just remember,we all support you,and we all believe that you can do very well.Believe in yourself,and you will thrive.Love,XXX

- -.楼主的数学老师屎的早啊.
设：楼号=x
房间号=y
如上得：
x+y=220
10x+y=364
联立方程组,解得x=16；y=204；

就是一个二元一次方程
假设楼号为x,房间号为y
x+y=220;10*x+y=364
求解结果为x=16,y=204
快速算法:从题意来看,房间号不变,楼号的9倍等於两个数字相减的结果,既144/9=16

解题思路：本题是一个等可能事件的概率，试验发生包含的事件数是50，碰到同性同学的事件有24个，碰到异性同学的事件有25个，做出两个事件的概率，比较出结果．

由题意知本题是一个等可能事件的概率，
试验发生包含的事件数是50，
碰到同性同学的事件有24个，
碰到异性同学的事件有25个，
做出两个事件的概率，
分别为[24/50]，[25/，50]
∴碰到异性同学的概率比碰到同性同学的概率大，
故选A

点评：
本题考点： 概率的意义．

考点点评： 本题考查等可能事件的概率公式，不管是怎样的一个题目在计算概率时，所用的方法都是一样的，做出两个事件的事件数，求比值做出概率．

解题思路：根据题意，折线统计图的折线分六段，即从家到学校，在学校一段时间，从学校回到家，中午在家吃饭或休息一段时间，又重复前一过程，据此分析，图C从家立即又到学校，从学校又立即回家不符合这一要求；图B是从家经过一段时间到学校，从学校立即即回家，从家立即又到学校，从学校又立即回家，符合要求；图A和图B差不多，只是中午在家过了一段时间，也不符合要求．

依据题意，折线统计图的折线分六段，即从家到学校，在学校一段时间，从学校回到家，中午在家吃饭或休息一段时间，又重复前一过程．
故选：B．

本题考点： 单式折线统计图．

考点点评： 此题主要考查利用图象解决实际问题．正确理解图象横纵坐标表示的意义，理解问题的过程，就能够通过图象得到问题的相应解决．

解题思路：设小文的步行速度为v，求出小莉骑自行车的速度；又知道从家到校的时间相同为5min，求出两人走的路程；根据题意（小莉比小文多走720m）列方程求解．

设小文的步行速度为v，则小莉骑自行车的速度为3v，
∵v=[s/t]，
∴小文走的路程：
s₁=vt，
小莉走的路程：
s₂=3vt，
由题意知，小莉比小文多走720m，
即：s₂-s₁=3vt-vt=720m，
∴v=[720m/2t]=[720m/2×5×60s]=1.2m/s．
由v=[s/t]得，s=vt=1.2m/s×5×60s=360m
故答案为：1.2；360．

点评：
本题考点： 速度公式及其应用．

考点点评： 本题也是数学上的追及问题，运动时间相同是隐含条件，利用好两人走的路程关系列方程是关键．

解题思路：这道题有多个单位“1”，可用倒推法每一个单位“1”求出来解．这道题从后往前做，根据“又借给了丁4本和剩下的[1/2]，最后剩下1本”入手，把借给了丁4本后剩下的看作单位“1”，1本所对的分率是[1/2]，所以这时的单位“1”的量是1÷[1/2]=2（本），由此可知借给丁之前有4+2=6（本）；这时原题可变为“先借给了甲2本和剩下的[1/4]，然后借给了乙3本和剩下的[1/3]，又借给了丙4本和剩下的[2/5]，最后还剩下6本”，同上方法可求出借给丙之前有6÷（1-[2/5]）+4=14（本）；借给乙之前有14÷（1-[1/3]）+3=24（本）；蔡明共有24÷（1-[1/4]）+2=34（本）．

（1）又借给了丙4本后，还剩的本数： （4+1÷12）÷（1-25）=（4+2）÷35=6×53=10（本）；（2）又借给了乙3本后，还剩的本数： （10+4）÷（1-13）=14÷23=14×32=21（本）；（3）借给了甲2本后还剩的本...

点评：
本题考点： 分数和百分数应用题（多重条件）．

考点点评： 这是一道有多个单位“1”，较复杂的分数应用题．
