club可知这里是指加入了一个英语俱乐部,结合选项,应用动词join,意为加入,指加入一个组织.因为句子是一般过去时,所以应用过去式joined.故选C.35.I'll go to visit my aunt in England _____ the summer holidays start.()A.while B.since C.until D.as soon as【考点】从属连词.【分析】暑假一开始,我就去拜访在英格兰的姑姑.【解答】答案:D while意为"当…的时候";since意为"自从…以来";until意为"直到才";as soon as意为"一…就…".根据"I'll go to visit"以及"the summer holidays start"可知主句用了一般将来时,后面的从句是一般现在时,所以要用as soon as,故选D.36.The astronaut is so tired that he ____ for eleven hours.()A.has been asleep B.has fallen asleepC.has gone to bed D.has gone to sleep【考点】现在完成时.【分析】这个宇航员是如此的累以至于他睡了11个小时了.【解答】答案:A.根据for eleven

to…意为"为…做出了巨大贡献",在句中是指"为学校的成长做出了巨大贡献".所以此处应用名词contribution,意为:"贡献".故选A.41.Thanks for your invitation,but I'm so sorry I can't go.I need to ________ my baby at home.()A.take away B.take off C.take care of D.take out of【考点】动词短语.【分析】谢谢你的邀请,但是非常抱歉我不能去.我需要在家照看我的孩子.【解答】答案:C.take away带走;take off起飞,脱掉;take care of照顾,照看;take out of取出.根据I need to ________ my baby at home,可知这里的意思应该是我需要在家照看我的孩子,take care

bb a-=-=⎧⎨⎩,∴1210ab==⎧⎨⎩;(2)设购买污水处理设备A型设备x台,B型设备(10−x)台,则:12x+10(10−x)⩽105,∴x⩽2.5,∵x取非负整数,∴x=0,1,2,∴有三种购买方案:①A型设备0台,B型设备10台;②A型设备1台,B型设备9台;③A型设备2台,B型设备8台.(3)由题意:240x+200(10−x)⩾2040,∴x⩾1,又∵x⩽2.5,x取非负整数,∴x为1,2.当x=1时,购买资金为:12×1+10×9=102(万元),当x=2时,购买资金为:12×2+10×8=104(万元),∴为了节约资金,应选购A型设备1台,B型设备9台.【点睛】此题考查一元一次不等式的应用,二元一次方程组的应用,解题关键在于理解题意列出方程.24. 对于某一函数给出如下定义:若存在实数p,当其自变量的值为p时,其函数值等于p,则称p为这个函数的不变值.在函数存在不变值时,该函数的最大不变值与最小不变值之差q称为这个函数的不变长度.特别地,当函数只有一个不变值时,其不变长度q为零.例如:下图中的函数有0,1两个不变值,其不变长度q等于1.(1)分别判断函数y=x-1,y=x-1,y=x2有没有不变值?如果有,直接写出其不变长度;(2)函数y=2x2-bx.①若其不变长度为零,求b值;②若1≤b≤3,求其不变长度q取值范围;(3) 记函数y=x2-2x(x≥m)的图象为G1,将G1沿x=m翻折后得到的函数图象记为G2,函数G的图象由G1和G2两部分组成,若其不变长度q满足0≤q≤3,则m的取值范围为 .【答案】详见解析.【解析】试题分析:(1)根据定义分别求解即可求得答案;(2)①首先由函数y=2x2﹣bx=x,求得x(2x﹣b﹣1)=0,然后由其不变长度为零,求得答案;②由①,利用1≤b≤3,可求得其不变长度q的取值范围;(3)由记函数y=x2﹣2x(x≥m)的图象为G1,将G1沿x=m翻折后得到的函数图象记为G2,可得函数G的图象关于x=m对称,然后根据定义分别求得函数的不变值,再分类讨论即可求得答案.试题解析:解:(1)∵函数y=x﹣1,令y=x,则x﹣1=x,无解;∴函数y=x﹣1没有不变值;∵y=x-1 =1x,令y=x,则1xx=,解得:x=±1,∴函数1yx=的不变值为±1,q=1﹣(﹣1)=2.∵函数y=x2,令y=x,则x=x2,解得:x1=0,x2=1,∴函数y=x2的不变值为:0或1,q=1﹣0=1;(2)①函数y=2x2﹣bx,令y=x,则x=2x2﹣bx,整理得:x(2x﹣b﹣1)=0.∵q=0,∴x=0且2x﹣b﹣1=0,解得:b=﹣1;②由①知:x(2x﹣b﹣1)=0,∴x=0或2x﹣b﹣1=0,解得:x 1=0,x 2=12b +.∵1≤b ≤3,∴1≤x 2≤2,∴1﹣0≤q ≤2﹣0,∴1≤q ≤2; (3)∵记函数y =x 2﹣2x (x ≥m )的图象为G 1,将G 1沿x =m 翻折后得到的函数图象记为G 2,∴函数G 的图象关于x =m 对称,∴G :y =22)22()(2(2)()m x x x x m m x x m -⎧-≥⎨--<⎩ .∵当x 2﹣2x =x 时,x 3=0,x 4=3; 当(2m ﹣x )2﹣2(2m ﹣x )=x 时,△=1+8m ,当△<0,即m <﹣18时,q =x 4﹣x 3=3;当△≥0,即m ≥﹣18时,x 5x 6 ①当﹣18≤m ≤0时,x 3=0,x 4=3,∴x 6<0,∴x 4﹣x 6>3(不符合题意,舍去); ②∵当x 5=x 4时,m =1,当x 6=x 3时,m =3;当0<m <1时,x 3=0(舍去),x 4=3,此时0<x 5<x 4,x 6<0,q =x 4﹣x 6>3(舍去);当1≤m ≤3时,x 3=0(舍去),x 4=3,此时0<x 5<x 4,x 6>0,q =x 4﹣x 6<3;当m >3时,x 3=0(舍去),x 4=3(舍去),此时x 5>3,x 6<0,q =x 5﹣x 6>3(舍去);综上所述:m 的取值范围为1≤m ≤3或m <﹣18. 点睛:本题属于二次函数的综合题,考查了二次函数、反比例函数、一次函数的性质以及函数的对称性.注意掌握分类讨论思想的应用是解答此题的关键.。

David said people with wrinkles (皱纹)could be called old people. 41 , Mary didn’t agree, for some people may gain wrinkles at an earlier age because of their 42 work. Then Lily expressed her idea that those reaching their 60s or more could be called old people. This time, Emily expressed her doubt and said some old people might still be 43 and trying to pursue(追求)their dreams, which makes them appear young. The clas s was over and we still didn’t reach any conclusion, so the teacher asked us to 44 about it after class.The question has 45 me of the saying of J.

She began 50 her painting lessons though she had all-white hair and lots of wrinkles. 51 , I didn’t support her idea of attending school at so old an age, but after seeing her painting 52 , I began feeling it a good 53 .So if we have our dreams and 54 after them, we aren’t old.

Just at that moment,Mr.Kwak called us back.I had to leave the game and of course I got a bad result.I couldn’t help thinking that if I were a bird living on Galapagos Island,I would be dead soon.The fun game made me realize that natural selection is really competitive(竞争的).Everyone is trying his or her best to—survive.61.What did the writer’s group use to pick up the beans?A.Spoons.B.Forks.C.Knives.D.Hands.62.How many beans did the writer get at last?A.None.B.One.

Whoever he met, he would like to show off(炫耀) how popular he was at school.One day, his grandpa said to him, “Mario, I know that you don’t have as many friends as you think. Many of them are not true to you.”Mario thought maybe his grandpa was right. However, he wasn’t sur e how he could test whether his schoolmates were real friends or not, so he asked his grandpa. The old man answered, “I have just exactly what you need. It’s in my room. Wait a minute.” The old man left, soon returning as if(好像) carrying something in his hand, but Mario could see nothing there.“Take it. It’s a very special chair. Because it’s invisible, it will be hard for you to sit on it. However, if you manage to sit on it, you can use the chair’s magic power(力量)to tell who your real friends are.”Mario took the strange invisible chair to school. At break time he asked everyone to form a circle, and he put himself in the middle, with his chair.“Nobody move. You’re about to see something amazing,” said Mario. Then he tried sitting on the chair. Havin g difficulty seeing it, he missed and fell to the ground. Everyone had a pretty good laugh. “Wait,wait,” said Mario, making another try. But again he missed the seat.Mario didn’t give up. He kept trying to sit on the magic chair. Finally, he did it. T his time he felt himself in mid-air.Then he experienced the magic that his grandpa had been talking about. Looking around, Mario saw George, Lucas and Diana holding him up, so he wouldn’t fall. But some schoolmates whom he had regarded as friends had done nothing but made fun of him. Mario was quite thankful to his grandpa, who helped him test who his true friends were.66.
