A VISIT TO THE MOON
Last month I was lucky enough to have a chance to make a trip into space with my friend Li Yanping, an astronomer. We visited the moon in our spaceship!
   Before we left, Li Yanping explained to me that the force of gravity would change three times on our journey and that the first change would be the most powerful. Then we were off. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earth’s gravity. It was so hard that we could not say anything to each other. Gradually the weight lessened and I was able to talk to him. “Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground.” I asked.“We are too far from the earth now to feel its pull,” he explained, “so we feel as if there is no gravity at all. When we get closer to the moon, we shall feel its gravity pulling us, but it will not be as strong a pull as the earth’s.” I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger.
   When we got there, I wanted to explore immediately. “Come on,” I said. “If you are right, my mass will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less!” I laughed and climbed down the steps from the spaceship. But when I tried to step forward, I found I was carried twice as far as on the earth and fell over. “Oh dear,” I cried, “walking does need a bit of practice now that gravity has changed.” After a while I got the hang of it and we began to enjoy ourselves.
   Leaving the moon’s gravity was not as painful as leaving the earth’s. But returning to the earth was very frightening. We watched, amazed as fire broke out on the outside of the spaceship as the earth’s gravity increased. Again we were pushed hard into our seats as we came back to land. “That was very exhausting but very exciting too,” I said. “Now I know much more about gravity! Do you think we could visit some stars next time?” “Of course,” he smiled, “which star would you like to go to?”  

 

文本分析:本课是人教版新课标模块3 Unit 4 Astronomy-Science of the Stars的using language部分,要通过课文的学习达到应用语言的目的。课文是一篇科幻游记,属于记叙文。文章记述了作者与朋友去月球旅行的全过程。从出发前朋友向作者解释万有引力的三次变化,到飞行过程中作者的不同体验及其作者与朋友的对话,到作者在月球上的所做所感,到返回地球时作者的收获和情感变化,无不渗透着科学探索的惊险刺激和乐趣所在。

学生分析:学对象普通高中高一班的学生,语言基础比较差,对科普类话题的文章兴趣较低,高考写作略有了解,并接触过一些不系统的练习。他们拥有基本英语获取信息、处理信息、分析问题和解决问题的能力,但是普遍存在新题型写作的困惑,所以需要特别注重新高考题型下提高学生用英语进行思维运用和表达的能力,尤其是写作能力和语言应用能力。

教学目标: 

1. 学生通过快速阅读技能,找出记叙文的五要素when, who, where, what, how教学重点

2. 通过阅读文本内容了解在地球,太空中,月球上重力的变化等科普知识以及找出作者在旅程中的不同体验和情感变化,理解spaceship, weightless, gravity, pull, float的意思同时借助学生对文本的理解,让学生感受科学探险的乐趣。(教学重点

3. 通过语法填空的形式,对文本重要词汇weightless, get hang of, now that等进行运用,复述文本主要内容,使阅读过程中获得的碎片信息连成一个整体的篇章框架。(教学重点

4. 通过阅读和复述的铺垫,学生通过找记叙文的5要素;寻找归纳主题句主要要点,用自己的话归纳提取要点等写作策略列出记叙文概要写作的要点提纲。(教学重难点

5. 通过小组讨论派代表写,学生对照概要写作要求评价,培养自我检查和合作能力

教学方法以学生为主体,以学生活动为主旋律,通过各种操练方式让学生通过自主学习,合作探究理解课文内容, 鼓励学生用所学知识技能解决问题,落实到写作。

课时安排: 40mins 

教学步骤:

课前导学:1. 课前安排学生阅读一篇关于the moon的文章,作为科普知识补充。

2. 观看视频“太空游之零重力飞行” “阿波罗月球行走 ” (激发学生兴趣,科普知识动态化)

Step1: Warming up  (2mins)

1. Ask students to do a science quiz:

• If I drop a pen, what will happen? Why?

• If I fell from a tree, what would happen to me?

• If I were in space, what would happen to me?

设计说明通过实物演示,图片展示将枯燥的科普知识通过直观的生活例子表现,以及之前导学知识的铺垫 使原本比较枯燥的科学知识变得生动形象,学生能讲出由于重力的变化,在地球和在太空中物体的不同表现,导出重要词汇float, weightless, gravity

2. How about on the moon? 引领学生一起学习这节课的话题 A Visit to The Moon.

设计说明】通过PPT的效果, 5秒钟后火箭升入太空的视觉动画,形象逼真,把文章标题变得更有体验性.

Step 2: Fast reading  (3mins)

1. What’s the genre(体裁) of the passage?  Narrative/ expository/ argumentative?

2. What’s the writing order of the passage? Time or space?

3. Find out the 5 factors: when, who, where, what, how.

设计说明】通过快速阅读策略,找出这篇文章的体裁,写作顺序,和记叙文的5要素。

Step3: Careful reading Para 2&3  (10mins)

Q1: How many times did the force of gravity change on the trip to the moon?

2. Read and fill in the blanks.

Change  

the first

the second

the third

When

off the earth

in space

on the moon

Gravity

The first change would be the _______ _______

as if there was ______ _______ at all.


His weight

heavy

w________


What happened

be____ ___ into our seats

could not_____ ____

_______ _______ around in our spaceship cabin.


设计说明】通过细读找出文本中相应的信息,通过表格形式更加直观地概括出三次重力的变化以及作者在飞行过程中的体验以及在月球上的所做所感。

Para 4  Read and find adjectives of his feelings.  

The changes of his feelings __________ -- _________ -- _________ -- __________--__________--  __________ --____________...

设计说明】通过找形容词理出作者的情感变化,让大家感受作者太空游时的惊险刺激和乐趣。

Step4Retelling  (8mins) After I returned to the earth, I was invited to share my experience to the Moon.

Last month, I was lucky to make a trip to the moon with LiYanping, ________ astronomer by spaceship.

Before the journey, he told me that the force of gravity would change three times on the journey. When we were off the earth, we __________(push) back into our seats__________(escape) the pull of the earth’s gravity. When we rose in space, we floated ____________(weight) around in our spaceship cabin. Then we got to the moon, we didn’t move more freely ________ fell over at first now________ gravity had changed, so walking did need a bit of practice. However, after I got the hang______ it, we began to enjoy ourselves. We had totally different experiences and________( feel) during the three changes.

We finally returned to the earth and felt _____________(exhaust)but excited.

设计说明】通过设置情境我回到地球后和其他人分享我的月球之行经历,让大家通过语法填空的形式复述文本主要内容,注重对文本重要词汇weightless, get hang of, now that进行运用,使阅读过程中获得的碎片信息连成一个整体的篇章框架,为概要写作做好铺垫。
