Students hold different ideas about it.30% of us think space exploration is not worthwhile. They think space is too far away from us and our daily life and is a waste of money. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.On the other hand，70% think space is worth exploring because we have benefited a lot from it，such as using satellites for communication and weather forecast. What’s more，with further space research，we may solve the population problem by moving to other planets one day. Also，space research will enable us to find new sources to solve the problem of energy shortages on the earth.As far as I am concerned, it is worthwhile to explore the space. Not only can it promote the development of society but also enrich our life. Step 11 Pair workExchange drafts with a partner.

Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

部编版语文八年级下册《核舟记》说课稿
(2)教学内容的设计，一般须遵从学生认知规律，由表及里，由浅入深、完整、生动地呈现事物或事理本身的美学价值。在整体感知课文的艺术美和解决文字障碍之后，通过动手做“核舟”、改写评点“解说词” ，使学生在动手做、动手改、动口说中，理清课文层次和说明顺序。最后，学生们再一次通读全文，使他们的认知经历了从语言文字到形象生动的表象，再到语言文字的完整过程。帮助他们将语言形式和语言内容紧密结合起来。吉尔伯特·海特在其《教学的艺术》一书中曾谈到：“如果我们不能获得一声出自内心的笑，那么这一天的教学就白费了”。通过演课本剧，加深了学生对课文的理解和记忆，有利于培养学生的思考能力，想象能力，逻辑思维能力和语言表达能力。也正是获取一声声出自内心的笑的一种行之有效的方法。
部编版语文七年级上册《猫》说课稿
一、说教材《猫》选自《郑振铎文集》，是人教版初中语文七年级下册第五单元的教学内容。本单元收录的五篇课文都是描写动物的佳作。本课更是通过描写与人类最亲近的动物之一——猫，来启示大家动物是人类的生存伙伴，它们和人类是平等的，正是有了它们，才使我们的世界丰富多彩、生趣盎然。因此，这些可爱的小生灵们值得我们用心去珍惜和呵护的。基于对教材的认识，根据新课程标准的要求。我指定了以下教学目标：1.自读课文，分别概括三只猫的不同来历、外形、性情、在家中的地位、结局以及对我的影响。2.跳读课文，通过作者对第三只猫的亡失而产生的心里感受与前两只猫进行对比，说出文章主旨以及你得到的启示。《猫》这篇文章描写了“我”三次的养猫经历，曲折的表达出同情、怜爱弱小者的思想感情，并从中告诉读者：凡事不可主观臆断，妄下结论，否则就难免出错，甚至造成无法弥补的悔恨。因此，我将教学目标的第一点：概括三只猫的不同来历、外形、性情、在家中的地位、结局以及对我的影响作为本课的教学重点。而说出文章主旨以及得到的启示作为本课教学难点。
