The theme of the section is “Describe space facts and efforts to explore space”. Infinitives are one of non-finite verbs, as the subjects, objects, predicative, attributes and adverbials. This unit is about space exploration, which is a significant scientific activity, so every scientific activity has strong planning. Therefore, using the infinitives to show its purpose, explanations or restrictions is the best choice.1. Learn the structure, functions and features of infinitives.2. Learn to summarize some rules about infinitives to show purpose and modify.3. Learn to use infinitives in oral and writing English. 1. Learn the structure, functions and features of infinitives.2.

The themes of this part are “Talk about how to become an astronaut” and “Talk about life in space”. As Neil Armstrong said “Mystery creates wonder and wonder is the basis of man’s desire to understand. Space is difficult for human to reach, therefore, humans are full of wonders about it. However, if wanting to achieve the dream of reaching the Moon, some of our human should work hard to be an astronaut at first. Part A(Talk about how to become an astronaut) is a radio interview in a radio studio, where the host asked the Chinese astronauts about his story how to become an astronaut. Yang Liwei told his dreamed to be an astronaut since childhood. Then he worked hard to get into college at 22. The next 10 years, he gradually became an experienced pilot. At the same time, to be an astronaut, he had to study hard English, science and astronomy and trained hard to keep in good physical and mental health and to practise using space equipment. Part B (Talk about life in space) is also an interview with the astronaut Brown, who is back on the earth. The host Max asked about his space life, such as his emotion about going back the earth, the eating, shower, brushing, hobbies and his work. Part A and Part B are interviews. So expressing curiosity about the guests’ past life is a communicative skill, which students should be guided to learn.1. Students can get detailed information about how Yang Liwei became an astronaut and Max’s space life.2. Students learn to proper listening strategy to get detailed information---listening for numbers and taking notes.3. Students can learn related sentences or phrases to express their curiosity like “ I wish to know...” “I’d love to know...”4. Students can learn more about the space and astronauts, even be interested in working hard to be an astronaut

The theme of this unit focuses on “space exploration.” Students will learn about the training and experience needed to become an astronaut. The text is mainly about the development of space exploration. On the one hand, the text helps students to have a good understanding about the great feats humans have achieved, on the other hand, they will further understand the contributions that we Chinese have achieved, and feel confident and proud about our homeland and strengthen their love for our country. The teacher should instruct students to aim high and study harder to make great progress in the space career if possible.1. Read about the development and value of space exploration.2. Explore the mysteries of the universe and the achievements in space exploration.3. Skillfully use the vocabulary of this text to cultivate self-study ability 4. Develop cooperative learning ability through discussion.1. Enable the Ss to talk about the development and value of space exploration.2.

⑦在我看来, 探索太空是值得的。As far as I am concerned, it is worthwhile to explore the space.Step 10 Writing---draftRecently, students in our class have had heated a discussion on whether space is worth exploring. 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.

一．情境引入：师：我们生活在一个变化的世界中,很多东西都在悄悄地发生变化你能从生活中举出一些发生变化的例子吗？生1：从春季到夏季气温在逐渐增加．生2：小树每年都在长高长粗．生3：我杯子里的水喝一口少一口．（说着就拿起杯子喝水，引起同学哈哈大笑）师： 你这个变化中有几个量在变化?生3：两个，一个是喝的口数，一个是水的多少？师： 它们的变化有什么联系吗？生3：有，随着喝的口数的增加，瓶中的水越来越少．生4：那我的这张纸越撕越小（此时该同学顺便从自己本子上撕下一张纸并将这张纸一次一次的撕下去，其他同学们点头称是）师： 你这个变化中又有几个量?它们又是怎么变化的？生4：两个，一个是撕的次数，另一个是纸的大小．师：那么哪个量随哪个量的变化而变化的呢？
北师大初中七年级数学下册用表格表示的变量间关系教案
解：(1)电动车的月产量y为随着时间x的变化而变化，有一个时间x就有唯一一个y与之对应，月产量y是时间x的因变量；(2)6月份产量最高，1月份产量最低；(3)6月份和1月份相差最大，在1月份加紧生产，实现产量的增值．方法总结：观察因变量随自变量变化而变化的趋势，实质是观察自变量增大时，因变量是随之增大还是减小．三、板书设计1．常量与变量：在一个变化过程中，数值发生变化的量为变量，数值始终不变的量称之为常量．2．用表格表示数量间的关系：借助表格表示因变量随自变量的变化而变化的情况．自变量和因变量是用来描述我们所熟悉的变化的事物以及自然界中出现的一些变化现象的两个重要的量，对于我们所熟悉的变化，在用了这两个量的描述之后更加鲜明．本节是学好本章的基础，教学中立足于学生的认知基础，激发学生的认知冲突，提升学生的认知水平，使学生在原有的知识基础上迅速迁移到新知上来

方法总结：观察表中的数据，发现其中的变化规律，然后根据其增减趋势写出自变量与因变量之间的关系式．三、板书设计1．用关系式表示变量间关系2．表格和关系式的区别与联系：表格能直接得到某些具体的对应值，但不能直接反映变量的整体变化情况；用关系式表示变量之间的关系简单明了，便于计算分析，能方便求出自变量为任意一个值时，相对应的因变量的值，但是需计算．本节课的教学内容是变量间关系的另一种表示方法，这种表示方法学生才接触到，学生感觉有点难．这节课的重点是让学生掌握用关系式与表格表示变量间的关系，难点是理解这两种表示方法的优缺点．就此问题，通过让学生对几个例子比较、讨论、总结、归纳两种方法的优点来解决，这样学生就能很好地区分这两种表示方法，并能对不同的问题选择恰当的方法

小学数学人教版五年级上册《用字母表示数》说课稿
2、教学目标新教材对学习目标的分解是以“学生的全域发展”作为标准进行的，更注重了学生的主体性和目标的可操作性。学习目标首先被分解为“知识和能力”、“过程和方法”、“情感、态度与价值观”。不仅解决了“学到什么”和“怎样学习”的问题，尤其解决了“喜欢学”和“主动学”的问题。根据本节课的地位和作用，依据教学大纲以及学生的认知结构心里特征，我制定了如下目标：① 知识目标：根据具体情境学会用字母表示数； ② 能力目标：能用含字母的式子表示数量关系； ③ 情感目标：通过教学引导学生从现实生活经历与体验出发，激发学生学习兴趣，体验用字母表示数的简明性，培养学生的抽象思维能力和归纳概括能力 ④ 教学重、难点：学会用字母表示数，用含字母的式子表示数量关系。二、说教法“教必有法而教无定法”，只有方法得当，才会有效。根据本课教学内容的特点和学生思维活动的特点，我采用了观察比较、顺势诱导、交流归纳的教学方法。
