Wasting food is a serious problem around the world. It is reported that up to 2 billion tons(吨) of food get lost or wasted every year. This is as much as half of all the food in the world. The UN Environment Program and the Food Agriculture Organization held a “Think, Eat, Save” program on Jan 24,2013 to help reduce food waste.
China, in recent years, has also experienced serious problems with wasted food. CCTV reported that the food Chinese people waste every year is enough to feed 200 million people for a year. So, Chinese have stepped up their efforts to cut food waste. The Clean Your Plate Campaign began on the Internet in January,2013. It calls on people to reduce food waste.
Luckily, the campaign has got the support of many. In a restaurant in Xinjiang, the owner gives the guests who have eaten all that they ordered a sticker(贴花). People can enjoy a free meal when they have 10 stickers. Almost all the restaurants in China have began to offer smaller dishes and encourage their guests to take leftover(剩余饭菜) home.
However, to reduce foo d waste is a big task, and it needs time. It’s important that everyone does their bit.
Here is some advice on how to reduce food waste.
1. Do not order too much in a restaurant. Only order as much as you want to eat. If you cannot eat all the food you ordered, take the rest of it home
2. Don’t be too picky about food. Some food may not taste great, but your body needs it.
3. Keep an eye on what food you have at home. Don’t buy too much, especially vegetables and fruit.
51. According to the passage, about _______tons of food is produced in the world every year.
A. 2 billion B. 4 billion C. 200 million D. 6 billion
52. The Clean Your Plate Campaign calls on people to _______.
A. do volunteer work B. work part time in restaurants
C. cut down on food waste D. wash your plates after dinner
53. The underlined word “picky” means _____ in Chinese.
A. 浪费的 B. 节约的 C. 值钱的 D. 挑剔的

What do people do with their old, out of date but still useful computers? Most people don't know how to deal with them. Many old computers are put away. Many more are simply thrown away as rubbish.
Finally, some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products. Dell, Hewlett Packard and other companies now also take back some old computers of their own brands.
In some countries, laws have been passed, too. Computer companies have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay for the cost. That will encourage them to make computers which are easier and cheaper to repair and upgrade(升级).
Yet many people are throwing away good computers, while others cannot afford them at all. Hundreds of organizations are working on this problem. They collect and repair old computers. Some also teach others how to repair computers. These repaired computers then go to schools, charities(慈善团体) or people who need them. Giving a used computer to one of these organizations can turn one person's rubbish into someone else's useful things and cut down waste, too.
54. How many computer company names are mentioned in the second paragraph?
A. One. B. Two. C. Three. D. Four.
55. According to the laws in some countries, computer companies must _____.
A. recycle most of their products B. collect all their used products
C. repair and upgrade old computers D. make more cheaper computers
56. What do the organizations do to solve the problem of old computers?
A. Help the computer companies to collect them.
B. Help people to le arn to use them.
C. Repair and send them to those who need them.
D. Turn all rubbish into useful things.
57. What is the main idea of this passage?
A. Encouraging to make cheap computers. B. Recycling old computers.
C. Helping those who need computers. D. Repairing old computers.

Last week, 169 Junior 1 students at No.35 Middle School of Shenyang took their first no-teacher exam. After the teacher handed out the exam paper, he left the room and never came back. A student collected in the papers when the exam ended.
“That test was not only a test of knowledge, but also a test of moral (道德). We wanted to show students how important honesty is,” said Cai Wenguo, the school’s headmaster. The school says no cheating (作弊)happened in the test. Next year, it wants 80% of its exams to be without teachers. But students have different ideas.
“I was happy and excited during the exam because my teachers trusted (信任) me,” said Lang Yudan, a 13-year-old girl in Class 11.
“Schools must trust students a lot not to use invigilators (监考人). But I think it is too early. Some students will cheat if there are no invigilators. And the students will not be able to ask for help when needed” said Hua Sha.
“I don’t like having invigilators in exams. When they walk around the classroom, they make me nervous. I would get higher marks without them in the room because I would feel more relaxed,” Liu Qingxi said.
“I think it’s very important to have invigilators in exams. Many students want to check their answers with each other after they have finished papers. And they can also keep the classroom in order when something unusual happens. They may make me nervous, but I still think we need them,” Shangguan Yuan said.
Not using invigilators may be a good idea. But before using it, schools must tell students the importance of honesty and try to find ways to solve something unusual in exams.
62. The passage mainly talks about ______________.
A. how to pass an exam B. how to make students honest
C. whether invigilators are needed in exams D. what a no- teacher exam is
63. No. 35 Middle School of Shenyang held a no-teacher exam to _________.
A. let the students have a good rest B. teach the students in a better way
C. help all the students pass the exam D. find whether the students were honest
64. From what the students have said, we know _____________
A. not all of them agree with the headmaster
B. invigilators are not needed at all.
C. something unusual never happens in exams
D. invigilators really help them a lot
65. In the sentence “And they can also keep the classroom in order when something unusual happens” “they” refers to (指)__________.
A. students B. headmasters C. the answers D. invigilators

We know that trees are useful in our everyday life. They give us 1 things,such as wood, oxygen, rubber, medicines 2 many other things. They can also tell us a lot about our climate. The following are the reasons. If you cut 3 a tree you can see that it has many rings. Most trees grow one ring 4 year. Because of this we know how old a tree is. A tree over a hundred 5 means that it has more than a hundred 6 . When the climate is dry or very cold the tree does not grow very much and their rings 7 usually thin. When it is wet and warm, the rings 8 thicker. If the rings are suddenly very thin or suddenly very thick, this means that the 9 changed suddenly. If we look at the rings on this tree, we can learn about the climate for a hundred years. We can see 10 changing today.

In most parts of the world, many students help their school make less pollution. They join in “environment(环境) clubs”. In an environment club, people work together to make our environment clean.
Here are the things students often do.
Turn off the water! Do you know that some toilets can waste(浪费) twenty to forty tons of water an hour?
In a year, that would fill a small river! In environment clubs, students mend those broken toilets.
No-car day. On a no-car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air, so remember:
Walk, jump, bike or run.
Use your legs! It’s lots of fun!
No-garbage(垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school!

于是入朝见威王,曰:“臣诚知不如徐公美。臣之妻私臣,臣之妾畏臣,臣之客欲有求于臣,皆以美于徐公。今齐地方千里,百二十城,宫妇左右莫不私王,朝廷之臣莫不畏王,四境之内莫不有求于王:由此观之,王之蔽甚矣。”
王曰:“善。”乃下令:“群臣吏民能面刺寡人之过者,受上赏;上书谏寡人者,受中赏;能谤讥于市朝,闻寡人之耳者,受下赏。”令初下,群臣进谏,门庭若市;数月之后,时时而间进;期年之后,虽欲言,无可进者。燕、赵、韩、魏闻之,皆朝于齐。此所谓战胜于朝廷。

王之蔽甚矣( ) 时时而间进 ( )

十年春,齐师伐我。公将战。曹刿请见。其乡人曰:“肉食者谋之,又何间焉?”刿曰:“肉食者鄙,未能远谋。”乃入见。问:“何以战?”公曰:“衣食所安,弗敢专也,必以分人。”对曰:“小惠未徧,民弗从也。”公曰:“牺牲玉帛,弗敢加也,必以信。”对曰:“小信未孚,神弗福也。”公曰:“小大之狱,虽不能察,必以情。”对曰:“忠之属也。可以一战。战则请从。”
公与之乘。战于长勺。公将鼓之。刿曰:“未可。”齐人三鼓。刿曰:“可矣。”齐师败绩。公将驰之。刿曰:“未可。”下视其辙,登轼而望之,曰:“可矣。”遂逐齐师。
既克,公问其故。对曰:“夫战,勇气也。一鼓作气,再而衰,三而竭。彼竭我盈,故克之,夫大国,难测也,惧有伏焉。吾视其辙乱,望其旗靡,故逐之。”

大家一定要在平时的练习中注意积累,同学们在初三时期要怎么做呢?接下来是读文网小编为大家带来的初三下学期语文期末模拟测试题,供大家参考。
一、(一)1.(1)入则无法家拂士 (2)共看明月应垂泪 (3)关关雎鸠 君子好逑 (4) 举杯邀明月,对影成三人(5)生于忧患而死于安乐也 (6)为什么我的眼里常含泪水? 因为我对这土地爱得深沉 (7)一鼓作气
(二)2.D
3.(1)凭您的力气,连魁父这座小山都不能削平,(又)能把太行、王屋(这两座山)怎么样呢?(2)于是就率领三个(能)挑担的子孙,凿石挖土,用畚箕(把土石)运到渤海边上。 4.妻是担忧(关切)的语气,智叟是讥笑(责难)的语气。
5.开放性试题,言之成理即可。【示例一】:看法:我认为愚公移山是不明智的。理由:移山费时费力,只凭人力是难于实现的。寓言最后不得不借夸娥氏二子之力来完成,这不正印证了这一点吗?且移山还可能导致自然环境的破坏,不如搬家、开路或绕道而行来得容易。【示例二】:看法:我认为愚公移山是聪明之举。理由:尽管移山比搬家或绕道困难得多,但移山才是彻底解决问题的办法。移山之举说明愚公有着远大的抱负,敢于挑战自然,而且坚信人定胜天的道理,他懂得只要代代坚持,就一定有实现愿望的一天。【示例三】:看法:我认为不能简单地以“智”、“愚”来认识愚公移山的行为。理由:从现实可行性和功利效益的角度来说,愚公确实“愚”。但从精神意志的角度来说,他知难而上、顽强不屈的精神和人定胜天的信念,不正给了我们积极的启示吗?
(三)6.示例:因为:① GPS系统运用的信号是较弱的那种无线电波,穿透能力不强。② 张凯在卧室不能同时接收4颗以上的卫星信号,就不能用GPS确定自己的位置。③ 在楼下,没有了墙体等阻碍GPS就能够接收到足够卫星信号,确定了自己的位置。(共6分。每点2分) 7.要点:①能接收到更多的卫星信号;②计算数据的速度快;③规划路径能力强;④地图数据精准详细。(答出三点即可,每两点2分)
(四)8.日出前,它包裹得严严紧紧,看不出一点要开的意思; 日落时,花瓣儿重新收缩起来。
9.因为它每天开放的花蕾都不同,每天新陈交替。
10.“闪”把太阳花开放时的动作写的活泼生动,给人一种调皮的感觉。
11.因为作为单独的太阳花朝开夕谢,只有一日。但是,每天,都有一批成熟了的花蕾在等待着开放。而且太阳花在开花的时候,朵朵都是那么精神充沛,不遗余力。
12.不管环境多么恶劣,依然勇敢面对,绝不低头。珍惜机会,尽情展示自己的风采。表演结束了,不留恋,不耍赖,坚决的离开,无私地发挥自己的余热。
(五)13.(1) ①乔纳森•斯威夫特格列佛游记②格列佛帮助利里浦特人打败了敌国(不来夫斯古帝国)。(2)小人国的宫廷游戏有两种,一种是绳上跳舞,另一种是在棍子上下跳来爬去。表演的是那些正在候补朝廷中重要官职的人和希望得到皇帝宠幸的人。
二、14. 栏目三:追寻历史渊源/探访名胜古迹 栏目四:欣赏地方艺术/品味民俗风情
15.郑樵,南宋著名的史学家,一生清贫简朴,厌恶官场黑暗,隐居山林,在新县的“夹漈草堂”,写就一言中极富盛名的史书《通志》。16. 四 欣赏地方艺术 莆田是一个有着浓厚艺术特色的地方,莆仙戏艺术引领你走进独特的莆田艺术世界。

10.如图,将正方形OABC放在平面直角坐标系中,O是原点,A的坐标为(1,),则点C的坐标为()
A. (﹣,1) B. (﹣1,) C. (,1) D. (﹣,﹣1)
考点: 全等三角形的判定与性质;坐标与图形性质;正方形的性质.
专题: 几何图形问题.
分析: 过点A作AD⊥x轴于D,过点C作CE⊥x轴于E,根据同角的余角相等求出∠OAD=∠COE,再利用“角角边”证明△AOD和△OCE全等,根据全等三角形对应边相等可得OE=AD,CE=OD,然后根据点C在第二象限写出坐标即可.
解答: 解:如图,过点A作AD⊥x轴于D,过点C作CE⊥x轴于E,
∵四边形OABC是正方形,
∴OA=OC,∠AOC=90°,
∴∠COE+∠AOD=90°,
又∵∠OAD+∠AOD=90°,
∴∠OAD=∠COE,
在△AOD和△OCE中,
,
∴△AOD≌△OCE(AAS),
∴OE=AD=,CE=OD=1,
∵点C在第二象限,
∴点C的坐标为(﹣,1).
故选:A.
点评: 本题考查了全等三角形的判定与性质,正方形的性质,坐标与图形性质,作辅助线构造出全等三角形是解题的关键,也是本题的难点.
11.关于一次函数y=﹣2x+3,下列结论正确的是()
A. 图象过点(1,﹣1) B. 图象经过一、二、三象限
C. y随x的增大而增大 D. 当x>时,y<0
考点: 一次函数的性质.
分析: A、把点的坐标代入关系式,检验是否成立;
B、根据系数的性质判断,或画出草图判断;
C、根据一次项系数判断;
D、可根据函数图象判断,亦可解不等式求解.
解答: 解:A、当x=1时,y=1.所以图象不过(1,﹣1),故错误;
B、∵﹣2<0,3>0,
∴图象过一、二、四象限,故错误;
C、∵﹣2<0,
∴y随x的增大而减小,故错误;
D、画出草图.
∵当x>时,图象在x轴下方,
∴y<0,故正确.
故选D.
点评: 本题主要考查了一次函数的性质以及一次函数与方程、不等式的关系.常采用数形结合的方法求解.
12.如图,矩形ABCD中,AB=8,AD=6,将矩形ABCD绕点B按顺时针方向旋转后得到矩形A′BC′D′.若边A′B交线段CD于H,且BH=DH,则DH的值是()
A. B. C. D.
考点: 矩形的性质;一元二次方程的应用;旋转的性质.
专题: 几何图形问题.
分析: 设DH的值是x,那么CH=8﹣x,BH=x,在Rt△BCH中根据勾股定理即可列出关于x的方程,解方程就可以求出DH.
解答: 解:设DH的值是x,
∵AB=8,AD=6,且BH=DH,
那么CH=8﹣x,BH=x,
在Rt△BCH中,DH=,
∴x2=(8﹣x)2+36,
∴x=,
即DH=.
故选C.
点评: 此题主要考查了正方形的性质,勾股定理等知识,解题关键是利用勾股定理列出关于所求线段的方程.

④日光灯管厂要检测一批灯管的使用寿命.
考点: 全面调查与抽样调查.
分析: 一般来说,对于具有破坏性的调查、无法进行普查、普查的意义或价值不大时,应选择抽样调查,对于精确度要求高的调查,事关重大的调查往往选用普查.
解答: 解:①了解全班同学的视力情况,适合普查;
②了解某地区中学生课外阅读的情况;,适合用抽查;
③了解某市百岁以上老人的健康情况,必须普查;
④日光灯管厂要检测一批灯管的使用寿命,适合抽样调查;
故答案为:②④.
点评: 本题考查了全面调查与抽样调查,由普查得到的调查结果比较准确,但所费人力、物力和时间较多,而抽样调查得到的调查结果比较近似.
