This unit is about the Internet, which has a great influence to our humans and our lives. During the Listening & Speaking & Talking and Reading and Thinking section, the influence in examples has been shown. Thus, use the Present Perfect Tense is appropriate. However, in order to show the justice or weaken the doer of the behavior/action, it’s better to use the Present Perfect Passive Voice than the Present Perfect Tense. Besides, having learned to use the Present Perfect Passive Voice, students can beautify their language in their writing. 1. Learn the structure of the Present Perfect Passive Voice and its functions. 2. Learn to change the sentences with the Present Perfect Passive Voice into the sentences with the Present Perfect Passive Voice. 3.

Listening and Speaking introduces the topic of “ask about online habits”. Many middle school students have been surfing the Internet for many years, but what they do with the Internet and how much time they spend every day may not be very clear to themselves, nor to other students. This section allows students to investigate their peers' Internet use, which is conducive to their mutual understanding and understanding of the Internet. It can also help them reflect on their own online behavior, learn from other people's good online habits, and get rid of their bad online behavior.The listening text of this section is an investigation interview. The investigators interview specific groups with the same questions to obtain information, so as to understand their views, practices or attitudes on this issue. There are two specific questions: “how much time do you spend online every day? What do you usually do online?”. The answers of the three respondents provide rich and different information, and achieve the purpose of the investigators. The oral discourse structure of survey interviews generally includes greeting and explaining the purpose of the interview, presenting the interview questions and the respondents' answers. Listening and Talking introduces the theme of “choosing the right application ". Listening text is a conversation between Laura and Xiao Bo. In this part of listening, “oink”; “piggy bank” may cause the students' hearing comprehension limitation. Oink refers to sound word and pig's sound. So, add some oink to my piggy bank is often used to describe "making a little money".1. Guide students to understand the content of listening texts in terms of listening for definitions.2. Cultivate students' ability to define words and understand an investigation interview.

三、畅意表达,理解英雄1.畅意表达。师:通过学习课文,你们明白了杨利伟为什么被称为“航天英雄”吗?请同学们大胆表达自己的想法。(生自由交流回答)预设 杨利伟是中国人民解放军航天员大队的首飞航天员,圆满完成了中国的第一次载人航天飞行任务。在充满不可预料的各种危险和意外的情况下,杨利伟为了国家、民族的利益奋不顾身,他具有不怕牺牲、敢于牺牲的大无畏精神和拼搏勇气,所以被称为“航天英雄”。2.理解英雄。师:是否只有为国捐躯者才能成为英雄呢?请同学们四人一小组讨论一下,然后说说你们组的意见。(生小组内交流讨论后,推荐代表在全班交流,师指导明确)预设 不是的。凡是为了国家、民族的利益而不顾个人安危,并为此奉献出自己的智慧和力量的人,都应该给予英雄的荣誉。杨利伟在中国的第一次载人航天飞行中,遇到许多突发事件,危难考验不时出现,如果没有大无畏的精神,没有为国家、民族做贡献的意识,是不可能临危不惧、坚持到底的。

3、文章怎样写“作为争取民主的战士”的闻一多先生的“说”与“做”的? 文章先写他的“说”,写他“说”的事实,由“小声说”到“向全国人民呼喊”,写他“说”的内容与目的反对独裁,争取民主。再叙他的“做”:起稿政治传单,在群众大会上大骂特务,走在游行示威队伍的前头,昂首挺胸,长须飘飘。用他的“说”和“做”揭示其争取民主、反对独裁的大无畏精神。 4、细读全文,画出精辟的语句,然后复述课文大意,并说出闻一多前期和后期思想品格上的主要特点,前后期有什么变化,又有什么共同的地方。闻先生前期为了探索其救国救民的出路而潜心学术,不畏艰辛,废寝忘食,十数年如一日,终于在学术上取得累累硕果。后期则投身于民主运动,敢于为人民讲话,面对凶残的敌人无所畏惧,视死如归,体现出民主战士的大勇,成为中国革命知识分子的楷模。闻先生在前期和后期所走的道路不同,反映了他对社会认识的变化。但作为一名卓越的学者,一名伟大的爱国者,一名言行一致的志士仁人,他却是始终如一的。
五、研读课文第一部分 我以为自己要牺牲了 1在这一部分中出现了什么意外?“在火箭上升到三四十公里的高度时,火箭和飞船开始急剧抖动,产生了共振。这让我感到非常痛苦。 ”“共振以曲线形式变化着,痛苦的感觉越来越强烈,五脏六腑似乎都要碎了。我几乎难以承受,觉得自己快不行了。” 2、这种共振是正常现象吗?这种现象后来 解决了吗?并非正常现象。 “飞船的共振主要来自火箭的振动。随后他们改进技术工艺,解决了这个问题。在“神舟六号”飞行时,情况有了很大改善;在后来的航天飞行中再没有出现过。 ”3、这一部分中表现了杨利伟什么精神?为祖国航天事业勇于牺牲的精神。第二部分 我看到了什么1、杨利伟在太空看到了什么?1、地球只是一段弧 2、准确判断各大洲和各个国家的方位 3、中国上空仔细辨别大概到哪个省了,正从哪个地区的上空 飞过,祖国的各个省份我大都看到了。
【感悟精彩句子】1. “今天,一架大水车来把我们扬到高处,游览古城的人要把这水车和清凉的水作一个美丽的背景摄影留念。”写到大水车的用意是什么? 大水车是丽江古城的标志性建筑,成为了丽江古城的地标,也是游客们一定要去拍照留念的地方。历史足迹明显,地域特色突出。2. 一些薄云掠过月亮时,就像丽江古城中,一个银匠,正在擦拭一只硕大的银盘。联想,古城的民俗难以忘怀。3.“我知道,作为一滴水,我终于以水的方式走过了丽江。”这样的结尾,体现了一滴水怎样的情怀?〖ZK)〗欣赏了风景如画的丽江,考察了“土”味浓郁的建筑,体会了丰富多彩的民俗民风,美感袭身,皆满足矣。融入更加广阔的江海,开始一滴水热情、奔放的新生活。
【活动目的】1. 使学生明礼诚信,做一个诚实守信,言行一致的人。2. 锻炼学生组织活动的筹划能力、展示学生的表演才艺。【活动准备】1. 学生事先准备好有关诚实守信的相关书面材料2. 班长为本次主题班会的主持人,准备好相关讲稿。【活动过程】一、激情导入男:我们的祖国是一个有着悠久历史、灿烂文明的大国。女: 中华民族是一个勤劳、勇敢、智慧民族。男:在我们漫漫的人生路上,什么不可丢弃?女:在我们遇到艰难困苦时,什么要永留身边?男:它在我们身边,离我们是那样近;它又离我们越来越远,是那样模糊。女:它是我们远行路上的灯塔,指引着我们前行的方向。合:它就是我们人生路上的朋友——诚信!即诚实守信。男:什么是诚实守信呢?(学生交流:诚实意味着实事求是,表里如一,说实话,做实事,不虚伪,不夸大其辞。诚实的人,不说谎话,不会欺骗自己,同时也不欺骗别人,做事大大方方,不做违背良心的事,实事求是,言行一致,说到做到。)
一、引入 主持人:感谢父母,他们给予你生命,抚养你成人;感谢老师,他们教给你知识,引领你做“大写的人”;感谢朋友,他们让你感受到世界的温暖;感谢对手,他们令你不断进取、努力;感谢太阳,它让你获得温暖;感谢江河,它让你拥有清水;感谢大地,它让你有生存空间。感恩,是一种心态,一种品质,一种艺术。感恩是礼貌。有人帮助了我们,我们随口说声“谢谢”,可能会给对方心里带来一股暖流。有人为我们付出了许多,我们感谢他,他可能会更加多的帮我们。怀着感恩的心,是有礼貌,是知恩图报。所以,感恩,是一种有礼貌的品质。感恩是画笔。学会感恩,生活将变得无比精彩。感恩描绘着生活,将生活中大块的写意,挥洒得酣畅淋漓;将生活中清淡的山水,点缀得清秀飘逸;将生活中细致的工笔,描绘得细腻精美。所以,感恩,是一种多样的艺术。下面我宣布“让我们都有一颗感恩的心”主题班会现在开始!
解析:水是生命之源,节约水资源是我们每个居民都应有的意识.题中给出假如每人浪费一点水,当人数增多时,将是一个非常惊人的数字,100万人每天浪费的水资源为1000000×0.32=320000(升).所以320000=3.2×105.故选B.方法总结:从实际问题入手让学生体会科学记数法的实际应用.题中没有直接给出数据,应先计算,再表示.探究点二:将用科学记数法表示的数转换为原数已知下列用科学记数法表示的数,写出原来的数:(1)2.01×104;(2)6.070×105.解析:(1)将2.01的小数点向右移动4位即可;(2)将6.070的小数点向右移动5位即可.解:(1)2.01×104=20100;(2)6.070×105=607000.方法总结:将科学记数法a×10n表示的数,“还原”成通常表示的数,就是把a的小数点向右移动n位所得到的数.三、板书设计借助身边熟悉的事物进一步体会大数,积累数学活动经验,发展数感、空间感,培养学生自主学习的能力.
光年是表示较大距离的一个单位, 而纳米(nanometer)则是表示微小距离的单位。1纳米= 米,即1米= 纳米。我们通常使用的尺上的一小格是一毫米(mm),1毫米= 米。可见,1毫米= 纳米,容易算出,1纳米相当于1毫米的一百万分之一。可想而知,1纳米是多么的小。超微粒子的大小一般在1~100 纳米范围内,故又称纳米粒子。纳米粒子的尺寸小,表面积大,具有高度的活性。因此,利用纳米粒子可制备活性极高的催化剂,在火箭固体燃料中掺入铝的纳米微粒,可提高燃烧效率若干倍。利用铁磁纳米材料具有很高矫顽力的特点,可制成磁性信用卡、磁性钥匙,以及高性能录像带等 。利用纳米材料等离子共振频率的可调性可制成隐形飞机的涂料。纳米材料的表面积大,对外界环境(物理的和化学的)十分敏感,在制造传感器方面是有前途的材料,目前已开发出测量温度、热辐射和检测各种特定气体的传感器。在生物和医学中也有重要应用。纳米材料科学是20世纪80年代末诞生并正在崛起的科技新领域,它将成为跨世纪的科技热点之一。
二、教学背景如今的孩子很多都是独生子女,一家人围着,疼都疼不过来,在一些孩子的心中认为父母等对自己的关心、养育都是理所当然的,大多“以自我为中心”,忘记对父母的付出说一声:“谢谢”。孩子对父母的养育变的冷漠,在家任性、霸道。人需要有一颗感恩的心,互相理解,世界才会充满爱。针对当前孩子存在这方面问题,需要加强对学生进行亲情教育。三、教学目标1、通过这次活动启迪学生去体会父母对自己的付出,更重要的是引导学生学会做人做事。2、联系实际,理解学会感恩能从多方面利于青少年成长,形成良好的道德品质。3、学会有一颗感恩的心,对于别人对自己的付出,懂得体会,感谢,学会与他人交往,为他们将来走向社会打下基础。四、教学重点1、唤起学生的感恩情感2、做一些可及的感恩行为,学会理解父母,树立健康心理
