(3)∵f (0)=0,f (1)=1,f (2)=0,f (3)=f (-1)=-f (1)=-1 又f (x )是以4为周期的周期函数.∴f (0)+f (1)+f (2)+…+f (2013)=f (2 012)+f (2 013)=f (0)+f (1)=1. 20.(本小题满分12分)解:(1)证明:连接AO ,在1AO A 中,作1O E AA ⊥于点E ,因为11//AA BB ,得1OE B B ⊥,因为1A O ⊥平面ABC ,所以1A O BC ⊥,因为AB =得A O B C ⊥,所以B C ⊥平面1AA O ,所以BC O E ⊥所以O E ⊥平面11BB C C , 又11,AO AA ===得215AOAE AA ==(2)如图所示,分别以1,,O A O B O A 所在的直线为x,y,z 轴建立空间直角坐标系,则A(1,0,0), C(0,-2,0), A 1(0.0,2),B(0,2,0)由(1)可知115A E A A = 得点E 的坐标为42(,0,)55,由(1)可知平面11BB C C 的法向量是42(,0,)55,设平面11A B C 的法向量(,,)n x y z = ,C 1x由100n AB n A C ⎧⨯=⎪⎨⨯=⎪⎩ ,得200x y y z -+=⎧⎨+=⎩,令1y =,得2,1x z ==-,即(2,1,1)n =-所以cos ,10||||O E n O E n O E n ⨯<>==⨯即平面平面11A B C 与平面BB 1C 1C10。

3、(1)某班七个同学体育课三步上篮的投篮数据 如下: 5、5、6、x、7、7、8。已知这组数据 的平均数是6,则这组数据的中位数是( ) A、7 B、6 C、5.5 D 5 (2)一组数据:x,8,10,10的中位数与平均数 相等,求这组数据的中位数。
所以,这组数据的中位数是138. (2)若增加一名选手,他的成绩是132,那么这组数据的 中位数又是多少? 解:将这些数据排序为:
127, 128,130, 132, 134,135 , 138,138, 139, 143,144, 145
所以,这组数据的中位数是 135+138= 136.5

She also believes in “Women’ s Liberation(解放)”.“I don’t wish that I were a man,” she says, “and I don’t think many women do. But I do wish that people would stop looking down upon us women.

But she is remembered as much for her aid work as for her acting.Born in Belgium in 1929, Audrey’ s father was B ritish and her mother was Dutch. Audrey was sent to live at a British school for part of her childhood. During World War II , she lived and studied in the Netherlands. Her mother thought it would be safe from German attacks. Audrey studied dance as a teenager and during college when she returned to London after the war. But she realized she wasn’ t going to be a ballerina. So she began taking acting parts in stage shows. Later she began to get small parts in movies.But it was Audrey Hepburn’ s move to America that brought her true fame. In 1951 she played the character “Gigi” in the Broadway play of the same name to great critical praise. Two years later, Roman Holiday made her a star at the age of 24. Audrey made more than 25 movies. Among her most popular roles was Holly Golightly in Breakfast at Tiffany’s in 1961. Three years later she played Eliza Doolittle in My Fair Lady.She was married two times and had one son by each husband. In 1989, the UN Children’ s Fund named Audrey a goodwill ambassad or. She travelled all over the world in support of UNICEF projects. The UN agency said she was a tireless worker. She often gave 15 interviews a day to gain money and support for UNICEF projects. Audrey Hepburn often said her loyalty to UNICEF was the result of her experiencesas a child during World War Ⅱ. She said she knew what it was like to be starving and to be saved by international aid. She was a goodwill ambassador until her death in 1993 from colon cancer.61.In Paragraph 1, “her aid work” means ________.A. winning an Academy Award as Best ActressB. taking acting parts in stage showsC. making moviesD. acting as a goodwill ambassador for UNICEF62.

Before this time health care had to be paid for by individuals.Nowadays central government is directly responsible for the NHS although it is administered by local health authorities. About 83 percent of the cost of the health service is paid for by general taxation and the rest is met from the National Insurance contributions paid by those in work. There are charges for prescription and dental care but many people, such as children, pregnant women, pensioners, and those on Income Support, are exempt from payment.Most people are registered with a local doctor (a GP, or General Practitioner) who is increasingly likely to be part of a health centre which serves the community.As the population of Britain gets older, the hospital service now treats more patients than before, although patients spend less time in hospital. NHS hospitals—many of which were built in the nineteenth century — provide nearly half a million beds and have over 480, 000 medical staff. The NHS is the biggest employer in Europe although Britain actually spends less per person on health care than most of her European neighbours.During the 1980s there was considerable restructuring of the Health Service with an increased emphasis on managerial efficiency and the privatization of some services (for example, cleaning). At the end of the 1980s the government introduced proposals for further reform of the NHS, including allowing some hospitals to be self-governing, and encouraging GPs to compete for patients. Patients would be able to choose and change their family doctor more easily and GPs would have more financial responsibility.

A short time after she had begun teaching, she set up a school for young girls in her grandparents’ home, which she conducted until she was thirty-three.She was forced to give up teaching at her grand-parents’ home, however, when she became ill, a few years of inactivity followed.In 1841 Dorothea began to teach again, accepting a Sunday school class in the East Cambridge, Massachusetts prison. Here she first came upon insane people (精神病人) locked up together with prisoners.In those days insane people were treated even worse than prisoners. There were only a few madhouses in the entire country.Therefore prisons, poor houses, and houses of correction were used to keep the insane.Dorothea Dix made a careful investigation(调查) of the inhuman treatment of the insane. It was considered unusual for a woman to devote herself to such work at that time. But this did not stop Dorothea Dix from providing proper medical care for the insane. Gradually, because of her investigations, conditions were improved. More than thirty mental institutions were founded or rebuilt in the United States because of her hard work. Dorothea also spread her investigations to England and to other parts of Europe.During the Civil War, Dorothea served as superintendent(负责人) of women hospital nurses in the Union army. When the war was over, she returned to her work of improving conditions for insane people.71. What kind of school was Dorothea’s school at Worcester, Massa chusetts?72. How did Dorothea Dix first realize the mistreatment of insane people?73. Why was Dorothea Dix’s work with the insane interrupted(中断)?74. How are the events of Dorothea Dix’s life presented in the passage?75. What does this article mainly tell us about?第四部分: 单词翻译及写作第一节:单词拼写。

2024年学校周周清制度(四篇)
2024年学校周周清制度一、周周清的对象主要是后进生对大多数能自查自纠,完成学习任务的学生,可让他们吃“自助餐”,即有计划地课外书籍、预习下周教学内容等,而不将他们列为周周清的对象。
二、周周清的目的是查漏补缺即查出本周所学的过不了关的知识点,使学生更有针对性地复习,并接受教师的有针对性的重点辅导,以确保没有一个学生掉队。
三、周周清的主要科目及内容英语:查本周所学的单词,要求须朗读、背诵、默写正确,句型口头操练流利,指定课文能熟背,重点句型会译写。
数学:能背本周所学概念,能口述本周所学例题的解答部分,能口答有关练习题。
理化:能背本周所学概念,正确口答所学的例题及练习题。
四、周周清的程序1、各班任课老师组织学生以自查、同桌互查、组与组对调查、教师抽查等多种形式,查清问题,作好记录并及时公布。
2、必要时,学部或年级备课组长组织班与班对调检查验收,时间为星期五或星期日。
3、如周周清过不了关的,任课老师得辅导、复验,直到限时(一般不超过周日晚上)过关为止。
4、双休日不整班上课(毕业班除外),不集中讲评作业,只对学生困难的学生个别辅导,其余学生应让他们自由活动,或进阅览室看书,或参加其它活动(培尖、娱乐、体育……),要有老师宏观组织,以确保活动有序、有效。
五、周周清的督查1、学部教务处组织督查、统计,并切实及时解决存在问题。
2、学校督学、校长办公室不定期检查学部周周清的情况,列入对学部的考核。
