三分陆地,七分海洋
世界海陆分布 不均匀 ,从南北半球看:陆地 主要分布在 北半球,海洋主要分布在 南半球 。但 无论哪个半球,都是 海洋 面积大于 陆地 面积。
海洋彼此相连,而陆地被海洋分割成大大小小的陆块。
水半球中海洋分布最集中,面积占90%; 陆半球中陆地面积最集中,面积占48%。
欧洲是欧罗巴洲的简称,在古代地中海人的语言中是 “西方日落之地”
非洲是阿非利加洲的简称。源自古希腊文,是“阳光 灼热的大陆”。
美洲是亚美利加洲的简称,以意大利航海家亚美 利哥的名字命名。它又分为北美洲和南美洲。
南美洲。
大洋洲是“大洋中的陆地”的意思。
南极洲因位于南极地区而得名。
太平洋:面积最大,约占世界海洋 总面积的一半以上。表层水温最高, 水体最深;岛屿最多,岛屿面积约占 世界岛屿总面积的一半以上。太平洋 西部海底的马里亚纳海沟深达11034米, 是世界上最深的地方。
江苏名师空中课堂
江苏名师空中课堂教育信息化是教育事业的重要组成部分。
近年来,江苏将数字化转型作为教育发展的重大战略,高位布局、系统谋划,取得了一系列显著成绩。
南师大附中新城初级中学黄山路分校是“南京市数字化校园”示范校。
学校通过智能环境建设,优化网络平台应用,推进智慧课堂实践,研发创新教育课程等一系列措施,将校园内所有能整合的信息予以链接互通,形成完整的流程和业务环路,优化了学校逻辑业务的管理能力,也提升了教学效果。
“我们学校在智慧校园创建的过程中,始终以智慧课堂教学为抓手,将传统课堂与智慧课堂相结合,各学科利用信息技术深度融合。
”南师大附中新城初级中学黄山路分校副校长阎冬介绍,从课前备课、课堂教学、课后作业与辅导等各个方面,让信息技术充分辅助教学,“通过课堂实践,课后反思,教师相互的研讨和交流,最后形成学科组统一应用智慧课堂平台相关的模式和方法,再返回到课堂进一步实践,促进了老师精准的‘教’,学生精准的‘学’。
”南师大附中新城初级中学黄山路分校智慧校园建设,是江苏教育信息化建设的一个缩影。
近年来,江苏坚持应用导向,积极推进智慧校园建设,不断激发学校教育数字化转型的内生动力。
通过连续三年的审核认定,全省85%以上的中小学和普通高校通过省级智慧校园认定。
截至2021年底,全省中小学智慧校园开展创新型教学活动的学校比例达72%。
江苏省电化教育馆馆长魏锡源介绍,“广大师生信息化的意识在不断的提升,在教育教学的场景当中,不断地去应用教育信息化的一些技术。
信息化技术的应用场景在不断丰富,比如说我们省现在在搞‘三个课堂’,主要就是‘名师空中课堂’‘网络名师工作室’和‘城乡结对互动课堂’,这三个课堂的建设。
”目前,江苏省“名师空中课堂”平台注册学生数869万,拥有覆盖中小学的课程资源2.3万余节。
“城乡结对互动课堂”搭建了城乡学校结对帮扶的桥梁,通过该项目,全省所有乡村小规模学校、乡镇寄宿制学校和城乡薄弱学校均纳入城乡结对帮扶体系,目前已覆盖全省1375所学校。

Chinese sports brand Li Ning also had a new design at New York Fashion Week in February 2019—it is the second time the brand shows its design at the NYFW. Chen Lijie, the brand’s designer, says his design comes from old Chinese truth (真理) that man is part of nature. “Chinese brands don’t use ‘cheap’ as a selling point any more. They are impressive and can go head to head with foreign brands (外国品牌).” says Shaun Rein, director of China Market ResearchGroup. Rome is not built in a day. Chinese designers spend much time trying to design the best and most fashionable clothes.These Chinese brands become so popular perhaps because of the easy online shopping and the fact that China is growing stronger than before. Also, more and more people begin to like Chinese culture.“We want to replace (代替) the words ‘made in China’ with ‘designed in China’, but there is a long way to go.” said Chinese designer Aric Chen.

It surveyed around 6,200 students from the four countries last year. You will find the answers to many of your questions in this report.Who studies hardest?Chinese students spend the most time studying.

It is quite advanced in many areas.You may not think that a small country is so strong in military technologies(军事科技). But Sweden was the first country to make a stealth warship(隐形战舰). Visby Class Corvette(维斯比级巡逻舰) is such kind of ship. It is hard to find by redar. And it was also the first to make an AIP engine(不依赖空气推进的引擎). With this engine, submarines(潜艇) can get power just under the water.Sweden also has a famous car brand called Volvo. You can see them a lot in some places in China.Some of you may also know IKEA, the world’s largest furniture retailer(零售商),Yes, It is Swedish ,too. In China, you can find IKEA in Beijing, Shanghai, Guangzhou, Chengdu, Nanjing and Shenzhen.When you want to listen to music, you may open QQ music. But many US teens prefer the Swedish one called Spotify. As of June 2016, Spotify had more than 100 million users.How can such a small country do well in so many fields? Rich resources like iron and wood may be one reason. They give the country a strong economy(经济). More importantly, Sweden has a good welfare system(福利制度). It allows people to live in a safe, equal andcomfortable place. And their free education, from kindergarten to university, focuses on science and innovation(创新). This provides the country with many talented people.37.Which of the following is a name for Swedish furniture brand?A. AIP engineB. VolvoC. IKEAD. Spotify38.Sweden can be advanced in so many fields because of .a. its rich resourcesb. its good welfare systemc. its strong military weaponsd. its good education systemA. abcB. abdC. acdD. bcd39.Which is TRUE according to this passage?A.There are several talented people in Sweden.B.Many US teens like Spotify better than QQ music.C.Sweden is smaller than Gansu province in China.D.With an AIP engine, submarines can get power above the water.40.The best title of this passage could be .A. Rich Resources in SwedenB. A Big and Pretty Country——SwedenC. Famous Brands in SwedenD. A Country Full of Wonders——SwedenELanguage changes all the time. New words and phrases appear and develop. The words and pronunciations used by young people in UK can be different to those used by grown-ups Living in a multicultural(多元文化的) society has an effect on language, especiallyon young people, whose friends are often from a mix of backgrounds. TV and music also have big influence on the language of the young. Often UK singers sing in American accents (口音) without realizing.Young British people use lots of language that you usually can’t find in most dictionaries. These informal words and expressions are known as ‘slang’. It is not possible ti make a complete list of modern British slang. By the time people finish the list, it would be out of date!New words come and go like fashions. However, here are a few examples:Safe, sorted, sound, cool or wicked all mean “That’s good” or “I understand”.People seldom use different tag question like … isn’t it?, can’t you? or don’t they?, they use innit.No longer say very, really or completely, people use well.Whatever means I don’t care.’He’s fine‘ or ‘He’s fit’ both mean ‘He looks good’. Fine and fit can describe a boy or a girl.Not everybody uses slang and not everybody likes it. A school in Sheffield, in the north of England, recently stopped its pupils using slang words such as hiya(hello), cheers and ta (both mean thank you). The head teacher says that if young people learn to speak‘correctly’ this will help them get a place at university and a good job.When British people use language like this, it’s no surprise that some students say they can’t unde rstand native(本土的) speakers. But perhaps learners don’t need to worry about communicating with native speakers so much. Research shows that most of the English spoken in the world today is spoken between non-native speakers of the language. In fact, when w e think about “International English”, there is no such things as a native or non-native speaker.41.In the UK, you can find little slang in ____________.A. young people’s languageB. TV programmesC. most dictionariesD. pop songs42.The writer uses the example of a school in Sheffield to say that _________.A. slang words can be used easilyB. slang is changing quicklyC. some people don’t like slangD. slang is out of date43.Which slang can be used in the following dialogue?—But the teacher says we can’t leave if we don’t finish.—_____________. I’m going.A. SoundB. FineC. CheersD. Whatever44.IF you want to learn more about the topic of this passage, you can search the Internet with the key words “_____________”.A. British peopleB. Language changesC. English slangD. English cultures45.You may find this passage in a book of _____________.A. novel(小说)B. cultureC. travelD. history第二卷(共55分)四、基础知识(共15小题,每题1分,计15分)A. 根据括号中所给的汉语写出单词,使句子意思完整准确46.I learned so many things about the world in my _________(物理) class.47.The ______________(总统) of the USA will come to our country.48.—Do you know that Chinese Team ____________(赢得) 26 golden medals in 2016 Rio Olympic Games.—How exciting!49.Everyone in modern society faces different kinds of _____________(竞争).50.

泰山佛光
泰山佛光是岱顶奇观之一。每当云雾弥漫的清晨或傍晚,游人 站在较高的山头上顺光而视,就可能看到缥缈的雾幕上,呈现出一 个内蓝外红的彩色光环,将整个人影或头影映在里面,恰似佛象头 上方五彩斑斓的光环,故得名“佛光”或“宝光”。泰山佛光是一 种光的衍射现象,它的出现是有条件的。据记载,泰山佛光大多出 现在6-8月中半晴半雾的天气,而且是太阳斜照之时。
泰山简介
泰山,古称东岳,又名岱山、岱岳、岱 宗、泰岳,为五岳之首。 泰山拔起于齐鲁丘 陵之上,长达二百公里。主峰突兀,山势险 峻,峰峦层叠,形成“一览众山小”和“群 峰拱岱”的高旷气势。泰山多松柏,更显其 庄严巍峨葱郁;又多溪泉,故而不乏灵秀与 缠绵。缥缈变幻的云雾则使它凭添了几分神 秘与深奥。它既有秀丽的麓区、静谧的幽区、 开阔的旷区,又有虚幻的妙区、深邃的奥区; 还有旭日东升、云海玉盘、晚霞夕照、黄河 金带等大自然奇观及石坞松涛、对松绝奇景 观,宛若一幅天然的山水画卷。
1、诗人“望”见了什 么?
造化钟神秀 阴阳割昏晓
荡 胸 生 曾 云
决眦入归鸟
会当凌绝顶,一览众山小
• 3、《望岳》中每一联都有“望”的意思,但望的角度不 同。试对此做具体的解释。
吟诵有所得,众神卫我形。 仙人游碧峰,处山河在,城春草木深。 • 感时花溅泪,恨别鸟惊心。
望
• 烽火连三月,家书抵万金。
• 白头搔更短,浑欲不胜簪。
天宝十四载(755)十一月,诗人赴奉先(今陕西 蒲城)探亲,未几,安禄山发动叛乱。次年五月,贼破 潼关,诗人被迫北上避难。七月,肃宗即位于灵武(今 属宁夏),诗人闻讯后前往投奔,不料中途为贼兵所俘, 被押至长安;因他官卑职小,未被囚禁。第二年四月, 他乘隙逃离长安,历尽千辛万苦,终于到达了当时朝廷 的所在地—凤翔县。
