【考点】角平分线的定义。

【分析】根据平角和角平分线的定义求得。

【解答】解:∵∠AOB是平角,∠AOC=30°,∠BOD=60°,

∴∠COD=90°(互为补角)

∵OM,ON分别是∠AOC,∠BOD的平分线,

∴∠MOC+∠NOD= (30°+60°)=45°(角平分线定义)

∴∠MON=90°+45°=135°。

故答案为135.

18、已知线段AB=10cm,直线AB上有一点C,且BC=4cm,M是线段BC的中点,则AM的长是 8或12 cm.

【考点】两点间的距离。

【分析】应考虑到A、B、C三点之间的位置关系的多种可能,即点C在点B的右侧或点C在点B的左侧两种情况进行分类讨论。

【解答】解:①如图1所示,当点C在点A与B之间时,

∵线段AB=10cm,BC=4cm,

∴AC=10﹣4=6cm.

∵M是线段BC的中点,

∴CM= BC=2cm,

∴AM=AC+CM=6+2=8cm;

②当点C在点B的右侧时,

∵BC=4cm,M是线段BC的中点,

∴BM= BC=2cm,

∴AM=AB+BM=10+2=12cm.

综上所述,线段AM的长为8cm或12cm.

故答案为:8或12.

(2)说明OF平分∠AOD.

【考点】角平分线的定义;对顶角、邻补角。

【分析】(1)根据邻补角的定义,即可求得∠2的度数,根据角平分线的定义和平角的定义即可求得∠3的度数;

(2)根据OF分∠AOD的两部分角的度数即可说明。

【解答】解:(1)∵∠BOC+∠2=180°,∠BOC=80°,

∴∠2=180°﹣80°=100°;

∵OE是∠BOC的角平分线,

∴∠1=40°。

∵∠1+∠2+∠3=180°,

∴∠3=180°﹣∠1﹣∠2=180°﹣40°﹣100°=40°。

(2)∵∠2+∠3+∠AOF=180°,

∴∠AOF=180°﹣∠2﹣∠3=180°﹣100°﹣40°=40°。

∴∠AOF=∠3=40°,

∴OF平分∠AOD.

第二种方式为:50+0.02x.

(2)设上网时长为x分钟时,两种方式付费一样多,

依题意列方程为:(0.05+0.02)x=50+0.02x,

解得x=1000,

答:当上网时全长为1000分钟时,两种方式付费一样多;

(3)当上网15小时,得900分钟时,

A方案需付费:(0.05+0.02)×900=63(元),

B方案需付费:50+0.02×900=68(元),

∵63<68,∴当上网15小时,选用方案A合算

Raisins(葡萄干) in ice cream, in chocolate, and in

cookies…Your favourite snacks cannot be without raisins!

But do you know how people get raisins from full and juicy

grapes? Dry(晒干) them in the sun? Well, that may be one way.

But people from Xinjiang have another way.

People there build many “blockhouses(碉堡)” out of earth(地面) near a grape garden. It is in these blockhouses that the best raisins are made.

People build many “blockhouses” on the hillside. The blockhouses are usually three metres tall and are as big as the size of a classroom.

They are quite different from the houses we live in. They have lots of holes in the wall. Inside there are many wooden shelves.

After picking the grapes, people put them on the shelves. Because of the hot weather, hot dry wind gets through the holes in the wall and dries the grapes up. 30 to 45 days later, the fruit will turn into soft, sweet raisins!

In around the year 535, people in Xinjiang started to send raisins as presents to the emperor(皇帝)。 This means that 1,500 years ago people began to know how to make raisins!

A. 树桩 B. 枝条 C. 架子 D. 洞孔

39、 Why are the “blockhouses” different from the houses we live in?

A. Because they have lots of holes in the wall.

B. Because they aren’t as big as the houses we live in.

C. Because there aren’t any windows in them.

D. Because there’re lots of grapes growing in them.

40、 Which of the followings is Not true?

A. People can find raisins in some ice cream, chocolate and cookies.

B. People only dry the full and juicy grapes in the sun to get the raisins.

C. The grapes need 30-45 days to turn into raisins in the blockhouses.

则6x﹣8表示:如果每人做6个,那么就比计划多8个。

13、如图是一个正方体展开图,把展开图折叠成正方体后,“我”字一面的相对面上的字是 梦 。

【考点】专题:正方体相对两个面上的文字。

【分析】正方体的表面展开图,相对的面之间一定相隔一个正方形,根据这一特点作答。

故答案为:梦。

14、如图,B处在A处的南偏西45°方向,C处在A处的南偏东15°方向,C处在B处的北偏东85°方向,则∠ACB的度数为 80° 。

【考点】方向角。

【分析】根据方向角,可得∠1,∠2,∠3的度数,根据平行线的性质,可得∠5,的度数,根据角的和差,可得∠2,4的度数,根据三角形的内角和定理,可得答案。、

【解答】解:如图:

B处在A处的南偏西45°方向,C处在A处的南偏东15°方向,C处在B处的北偏东85°方向,

∴∠1=45°∠2=85°,∠3=15°,

由平行线的性质得∠5=∠1=45°。

由角的和差得

∠6=∠2﹣∠5=85°﹣45°=40°,

∠4=∠1+∠3=45°+15°=60°,

由三角形的内角和定理得∠ACB=180°﹣∠6﹣∠4=180°﹣40°﹣60°=80°,

故答案为:80°。

15、如图,将△ABE向右平移2cm得到△DCF,如果△ABE的周长是16cm,那么四边形ABFD的周长是 20cm 。

【考点】平移的性质。

【分析】根据平移的性质可得DF=AE,然后判断出四边形ABFD的周长=△ABE的周长+AD+EF,然后代入数据计算即可得解。

【解答】解:∵△ABE向右平移2cm得到△DCF,

∴DF=AE,

∴四边形ABFD的周长=AB+BE+DF+AD+EF,

=AB+BE+AE+AD+EF,

=△ABE的周长+AD+EF,

∵平移距离为2cm,

∴AD=EF=2cm,

∵△ABE的周长是16cm,

∴四边形ABFD的周长=16+2+2=20cm.

故答案为:20cm.

16、按下面的程序计算,若开始输入的值x为正数,最后输出的结果为11,则满足条件的x的不同值分别为 5,2,0.5 。

【考点】代数式求值。

【分析】解答本题的关键就是弄清楚题图给出的计算程序。由于代入x计算出y的值是11>10,符合要求,所以x=5即也可以理解成y=5,把y=5代入继续计算,得x=2,依此类推就可求出5,2,0.5.

【解答】解:依题可列,

y=2x+1,

把y=11代入可得:x=5,即也可以理解成y=5,

把y=5代入继续计算可得:x=2,

把y=2代入继续计算可得:x=0.5,

把y=0.5代入继续计算可得:x<0,不符合题意,舍去。

∴满足条件的x的不同值分别为5,2,0.5.

三、解答题(本大题共12小题,共102分)

17、计算:

(1)[﹣5﹣(﹣11)]÷(﹣ ÷ );

【解答】解:(1)原式=6÷(﹣ ×4)=6÷(﹣6)=﹣1;

(2)原式=﹣4﹣3+(﹣8)÷(﹣ )=﹣4﹣3+16=9.

18、解方程:

(1)6+2x=14﹣3x(写出检验过程);

(2) =1.

【考点】解一元一次方程。

【分析】(1)方程移项合并,把x系数化为1,求出解,检验即可;

(2)方程去分母,去括号,移项合并,把x系数化为1,即可求出解。

【解答】解:(1)移项得:3x+2x=14﹣6,

合并得:5x=8,

解得:x=1.6,

当x=1.6时,左边=6+3.2=9.2,右边=14﹣4.8=9.2,

∵左边=右边,

∴x=1.6是方程的解;

(2)去分母得:3(x+2)﹣2(2x﹣3)=12,

去括号得:3x+6﹣4x+6=12,

解得:x=0.

19、如图,点B在线段AD上,C是线段BD的中点,AD=10,BC=3.求线段CD、AB的长度。

【考点】两点间的距离。

【分析】根据线段中点的定义可得BC=CD;再根据AB=AD﹣BC﹣CD,代入数据进行计算即可得解。

【解答】解:∵C是线段BD的中点,

∴BC=CD,

∵BC=3,

∴CD=3;

由图形可知,AB=AD﹣BC﹣CD,

∵AD=10,BC=3,

∴AB=10﹣3﹣3=4.

20、一个角的补角加上10°后,等于这个角的余角的。3倍,求这个角以及它的余角和补角的度数。

【考点】余角和补角。

【分析】设这个角为x°,则得出方程180﹣x+10=3(90﹣x),求出即可。

【解答】解:设这个角为x°,

则180﹣x+10=3(90﹣x),

解得:x=40.

即这个角的余角是50°,补角是140°。

21、化简求值:(3ab2﹣a2b)﹣2(2ab2﹣a2b),其中a=1,b=﹣2.

【考点】整式的加减—化简求值。

【分析】先化简,然后将a与b的值代入即可求出答案。

【解答】解:原式=3ab2﹣a2b﹣4ab2+2a2b

=﹣ab2+a2b,

当a=1,b=﹣2时,

原式=﹣1×1×4+1×(﹣2)

=﹣6;

22、证明:多项式16+a﹣{8a﹣[a﹣9﹣3(1﹣2a)]}的值与字母a的取值无关。

【考点】整式的加减。

【分析】先将多项式16+a﹣{8a﹣[a﹣9﹣3(1﹣2a)]}进行化简,化简时去括号,然后合并同类项,以此来判断是否与a的取值无关。

【解答】证明:16+a﹣{8a﹣[a﹣9﹣3(1﹣2a)]}

=16+a﹣{8a﹣[a﹣9﹣3+6a]}

=16+a﹣{8a﹣a+9+3+6a}

=16+a﹣8a+a﹣9﹣3+6a

=4.

故多项式的值与a的值无关。

23、如图,EF⊥BC,AD⊥BC,∠1=∠2,∠B=30°。求∠GDB的度数。

请将求∠GDB度数的过程填写完整。

解:因为EF⊥BC,AD⊥BC,

所以∠BFE=90°,∠BDA=90°,理由是 垂直的定义 ,

即∠BFE=∠BDA,所以EF∥ AD ,理由是 同位角相等,两直线平行 ,

所以∠2= ∠3 ,理由是 两直线平行,同位角相等 。

因为∠1=∠2,所以∠1=∠3,

所以AB∥ DG ,理由是 内错角相等,两直线平行 ,

所以∠B+ ∠GDB =180°,理由是 两直线平行,同旁内角互补 。

又因为∠B=30°,所以∠GDB= 150° 。

【考点】平行线的判定与性质。

【分析】先根据垂直的定义得出∠BFE=90°,∠BDA=90°,故可得出EF∥AD,再由平行线的性质得出∠2=∠3,利用等量代换得出∠1=∠3,故AB∥DG,再由∠B=30°即可得出结论。

【解答】解:∵EF⊥BC,AD⊥BC,

∴∠BFE=90°,∠BDA=90°(垂直的定义),即∠BFE=∠BDA,

∴EF∥AD(同位角相等,两直线平行),

∴∠2=∠3(两直线平行,同位角相等)。

又∵∠1=∠2,

∴∠1=∠3,

∴AB∥DG(内错角相等,两直线平行)

∴∠B+∠GDB=180°(两直线平行,同旁内角互补)。

又∵∠B=30°,

∴∠GDB=150°。

故答案为:垂直的定义,AD,同位角相等,两直线平行,∠3,两直线平行,同位角相等,DG,内错角相等,两直线平行,∠GDB,两直线平行,同旁内角互补,150°。

24、如图,点P是∠AOB的边OB上的一点过点P画OB的垂线,交OA于点C;

(1)过点P画OA的垂线,垂足为H;

(2)线段PH的长度是点P到 OA 的距离, 线段CP的长度 是点C到直线OB的距离。线段PC、PH、OC这三条线段大小关系是 PH

【考点】点到直线的距离;垂线段最短。

【分析】(1)过点P画OA的垂线,即过点P画∠PHO=90°即可,

(2)利用点到直线的距离可以判断线段PH的长度是点P到OA的距离,PC是点C到直线OB的距离,线段PC、PH、OC这三条线段大小关系是PH

【解答】解:(1)如图:

(2)线段PH的长度是点P到直线OA的距离,

线段CP的长度是点C到直线OB的距离,

根据垂线段最短可得:PH

故答案为:OA,线段CP,PH

25、周末小明陪爸爸去陶瓷商城购买一些茶壶和茶杯,了解情况后发现甲、乙两家商店都在出售两种同样品牌的茶壶和茶杯,定价相同:茶壶每把定价30元,茶杯每只定价5元。两家都有优惠:甲店买一送一大酬宾(买一把茶壶赠送茶杯一只);乙店全场9折优惠。小明爸爸需茶壶5把,茶杯x只(x不小于5)。

(1)若在甲店购买,则总共需要付 5x+125  元;若在乙店购买,则总共需要付 4.5x+135  元。(用含x的代数式表示并化简。)

(2)当需购买15只茶杯时,请你去办这件事,你打算去哪家商店购买?为什么?

【考点】列代数式。

【分析】(1)由题意可知,在甲店买一把茶壶赠送茶杯一只,故需付5只茶壶的钱和x﹣5只茶杯的钱,已知茶壶和茶杯的钱,可列出付款关于x的式子;在乙店购买全场9折优惠,同理也可列出付款关于x的式子;

(2)计算后判断即可。

【解答】解:(1)设购买茶杯x只,

在甲店买一把茶壶赠送茶杯一只,且茶壶每把定价30元、茶杯每只定价5元,

故在甲店购买需付:5×30+5×(x﹣5)=5x+125;

在乙店购买全场9折优惠,

故在乙店购买需付:30×0.9×5+5×0.9×x=4.5x+135;

(2)选择甲店购买,理由:到甲店购买需要200元,到乙店购买需要202.5元。

∵200<202.5,

∴选择甲店购买,

故答案为:(1)(5x+125),(4.5x+135)

26、某数学兴趣小组研究我国古代《算法统宗》里这样一首诗:我问开店李三公,众客都来到店中,一房七客多七客,一房九客一房空。诗中后两句的意思是:如果每一间客房住7人,那么有7人无房可住;如果每一间客房住9人,那么就空出一间房。

(1)求该店有客房多少间?房客多少人?

(2)假设店主李三公将客房进行改造后,房间数大大增加。每间客房收费20钱,且每间客房最多入住4人,一次性定客房18间以上(含18间),房费按8折优惠。若诗中“众客”再次一起入住,他们如何订房更合算?请写出你作出这种决策的理由。

【考点】一元一次方程的应用。

【分析】(1)根据题意设出房间数,进而表示出总人数得出等式方程求出即可;

(2)根据已知条件分别列出两种住房方法所用的钱数,进而比较即可。

【解答】解:(1)设客房有x间,则根据题意可得:

7x+7=9x﹣9,

解得x=8;

即客人有7×8+7=63(人);

答:客人有63人。

(2)如果每4人一个房间,需要63÷4=15 ,需要16间客房,总费用为16×20=320(钱),

如果定18间,其中有四个人一起住,有三个人一起住,则总费用=18×20×0.8=288(钱)<320钱,

所以他们再次入住定18间房时更合算。

答:他们再次入住定18间房时更合算。

27、(1)观察思考

如图,线段AB上有两个点C、D,请分别写出以点A、B、C、D为端点的线段,并计算图中共有多少条线段;

(2)模型构建

如果线段上有m个点(包括线段的两个端点),则该线段上共有多少条线段?请说明你结论的正确性;

(3)拓展应用

8位同学参加班上组织的象棋比赛,比赛采用单循环制(即每两位同学之间都要进行一场比赛),那么一共要进行多少场比赛?

请将这个问题转化为上述模型,并直接应用上述模型的结论解决问题。

【考点】直线、射线、线段。

【分析】(1)从左向右依次固定一个端点A,C,D找出线段,最后求和即可;

(2)根据数线段的特点列出式子化简即可;

(3)将实际问题转化成(2)的模型,借助(2)的结论即可得出结论。

【解答】解:(1)∵以点A为左端点向右的线段有:线段AB、AC、AD,

以点C为左端点向右的线段有线段CD、CB,

以点D为左端点的线段有线段DB,

∴共有3+2+1=6条线段;

(2) ,

理由:设线段上有m个点,该线段上共有线段x条,

则x=(m﹣1)+(m﹣2)+(m﹣3)+…+3+2+1,

∴倒序排列有x=1+2+3+…+(m﹣3)+(m﹣2)+(m﹣1),

∴2x= =m(m﹣1),

∴x= ;

(3)把8位同学看作直线上的8个点,每两位同学之间的一场比赛看作为一条线段,

直线上8个点所构成的线段条数就等于比赛的场数,

因此一共要进行 =28场比赛。

28、如图,OB、OC是∠AOD的两条射线,OM和ON分别是∠AOB和∠COD内部的一条射线,且∠AOD=α,∠MON=β。

(3)根据上面的结果,请填空:当∠AOM=n∠BOM,∠DON=n∠CON时,∠BOC=  β﹣ α 。(n是正整数)(用含α和β的代数式表示)。

【考点】角的计算。

【分析】(1)根据∠BOC=∠MON﹣∠BOM﹣∠CON,等量代换即可表示出∠BOC的大小;

(2)①当∠AOM=2∠BOM,∠DON=2∠CON时,等量代换即可表示出∠BOC的大小;②当∠AOM=3∠BOM,∠DON=3∠CON时,等量代换即可表示出∠BOC的大小;

(3)当∠AOM=n∠BOM,∠DON=n∠CON时,等量代换即可表示出∠BOC的大小;

【解答】(1)∵∠AOM=∠BOM= ∠AOB,∠CON=∠DON= ∠COD,

∵∠BOC=∠MON﹣∠BOM﹣∠CON=∠MON﹣ ∠AOB﹣ ∠COD=∠MON﹣ (∠AOB+∠COD)=∠MON﹣ (∠AOD﹣∠BOC)=β﹣ (α﹣∠BOC)=β﹣ α+ ∠BOC,

则∠BOC=2β﹣α。

(2)①当∠AOM=2∠BOM,∠DON=2∠CON时,

∵∠BOM+∠CON= (∠AOM+∠DON)= (α﹣β),

∴∠BOC=∠MON﹣(∠BOM+∠CON)=β﹣ (α﹣β)= β﹣ α;

②当∠AOM=3∠BOM,∠DON=3∠CON时,

∵∠BOM+∠CON= (∠AOM+∠DON)= (α﹣β),

∴∠BOC=∠MON﹣(∠BOM+∠CON)=β﹣ (α﹣β)= β﹣ α;

(3)当∠AOM=n∠BOM,∠DON=n∠CON时,

∵∠BOM+∠CON= (∠AOM+∠DON)= (α﹣β),

∴∠BOC=∠MON﹣(∠BOM+∠CON)=β﹣ (α﹣β)= β﹣ α;

故答案为: β﹣ α。
