Unit 4 Space exploration教学设计科目：英语 课题：Discovering Useful Structures 课时：1课时教学目标与核心素养：知识目标：识别和分析充当定语或状语的不定式的用法。能力目标：通过自学和练习掌握不定式充当定语或状语的用法。情感目标：使用不定式来描述空间事实和探索空间的努力。教学重点：1. 帮助学生确定不定式充当定语或状语的用途。2. 引导学生使用不定式来描述太空和探索太空。3. 设计具体情境，让学生使用不定式充当定语或状语。教学难点：如何在实际情况下使用充当定语或状语的不定式。课前准备：多媒体，黑板，粉笔教学过程：一、Pre-class1. Greeting2. Leading-in教师活动：在课件上展示以下两句话，并引导学生思考这两句话的含义。Mystery creates wonder and wonder is the basis of man's desire to understand.——Neil Armstrong To succeed, you must accept all the challenges, can't just accept the ones you like.——Mike Gaffka活动目的：通过两句名言导入课堂，先让学生领悟两句话的内涵，然后引导学生观察发现句子中的不定式，思考其功能和含义，引出本单元的主体语法结构。二、     While-class 学生活动：1.学生两人一组观察和讨论活动1中的五个句子，尝试说出每个句子中动词不定式的功能和意义。若学生对句子成分并不熟悉，教师可根据每个句子的意思将动词不定式转换为从句，让学生通过对比了解它们所充当的句子成分。例如：原句：I trained for a long time to fly airplanes a fighter pilot.As we all know, an astronaut needs to be healthy and calm in order to work in space.First of all，you must be intelligent enough to get a related college degree.Some scientists were determined to help humans realise the dream to explore space.On 12 April 1961，Yuri Gagarin became the first person in the world to go into space.从句：infinitives as adverbials to express purposes：I trained for a long time in order that I could fly airplanes a fighter pilot.As we all know，an astronaut needs to be healthy and calm in order that he/she can work in space.infinitive as the adverbial to show the result：First of all，you must be intelligent enough so that you could get a related college degree.infinitives as attributes to modify sth.：Some scientists were determined to help humans realise the dream which was to explore space.On 12 April 1961，Yuri Gagarin became the first person in the world who went into space.总结1：infinitives as attributes to modify sth.不定式（to do）的功能和意义：可作状语，表目的或结果，多可转化为 in order that/so that引导的状语从句；为强调目的，可用 in order to/so as to 。可作定语，起修饰或限定作用，可转化为定语从句。2.学生得出动词不定式可作定语和作状语的结论后，教师可让他们从单元中找出更多类似的句子，也可提供更多的例句帮助学生归纳这两种用法的特点。People have always wanted to learn more about space, and scientists work hard to find answers. (adverbial)They make vehicles to carry brave people into space to find out the secrets of the universe. (attribute;adverbial)They also really wish to discover other planets that are suitable enough to support life. (adverbial)                America's NASA space agency launched Voyager 1 on 5 September 1977 to study deep space. (adverbial)These disasters made everyone sad and disappointed, but the desire to explore the universe never died. (attribute)                                                                  China became the third country in the world to independently send humans into space in 2003. (attribute)Then Shenzhou 6 and 7 completed a second manned orbit and the first Chinese spacewalk, followed by the vehicle Jade Rabbit being sent to the moon to study its surface. (adverbial)    After that, China launched the Tiangong 2 space lab into space and Tianzhou 1 to dock with it. (adverbial) This signalled one step further in China’s plan to establish a space station in the future. (attribute)More recently, China has sent Chang’e 4 to explore the surface of the far side of the moon to make measurements and observations. (adverbial)                                            Europe, the US, and China all have plans to further study and explore planets like Mars and Jupiter. (attribute)不定式作状语表目的：         … work hard to find answers …       … carry brave people into space to find out the secrets …       … launched Voyager 1 … to study deep space …       … sent Chang’e 4 to explore the surface …       … launched … Tianzhou 1 to dock with it.       … being sent to the moon to study its surface …       … be healthy and calm in order to work in space.       …sent Chang’e 4 to explore the surface不定式作状语表结果：       … are suitable enough to support life.        … be intelligent enough to get a related college degree. 总结2：不定式作状语：可以表示目的或结果，多可转化为 in order that/so that引导的状语从句；常用结构：in order to/so as to（表目的）be+adj.+ enough to do（表结果）不定式作定语起修饰作用：       … vehicles to carry brave people into space …       … the desire to explore the universe never died.        … China’s plan to establish a space station …       … plans to … study and explore planets …       … their dream to explore space …       … the third country … to … send humans into space …       … the first person … to go into space.总结3：不定式作定语：起修饰或限定作用，可转化为定语从句；可修饰名词、数词、代词等，常置于被修饰词后；多表示将来的动作；后接不定式作定语的名词有：desire，dream，plan，goal等。拓展：It was very tiring, but I was so proud to have the opportunity. 总结4：不定式作状语：可以表示原因，可根据其在语境中的意义，转化为相应的状语从句。常用结构：be+ proud/pleased/.+to do（表原因）3.根据所学语法完成活动2。Mankind has always been curious about the universe and many people have dreamt that one day they would fly into space.→.… many people have the dream to fly into space one day.Astronauts’ bones and muscles can get very weak in space due to the lack of gravity, so they need to exercise every day, which will help them stay healthy.→.… so they need to exercise every day to/in order to/so as to stay healthy.Astronauts have to use tape to stick everything down while working in space because everything would float off otherwise.→.…  while working in space to/in order to/so as to keep everything from floating off.During a spacewalk, astronauts have to move slowly so that they can keep their bodies under control.→.… move slowly to/in order to/so as to keep their bodies under control.   三、After-class完成活动3，在小组内讨论结果。Sending people to other planets or even beyond the solar system is not an easy goal _________ (achieve). One of the problems is that the trip would take a very long time. For example, _________ (use) the current technology, it would take over two years _________ (get) to the closest planet, Mars, and back. Although light is the fastest thing _________(know) in the universe, it could take more than four years to reach the nearest star system. Will scientists figure out a way _________(store) sufficient food and water for the long journey? Is it possible to travel faster than light? No one knows the answers yet. However, space scientists never give up. They are experimenting with growing crops in space so as _________(help) astronauts get enough food on longer journeys through space.答案：to achieve; using; to get; known; to store; to help四、Summary 不定式（to do）的功能和意义：可作状语，表目的或结果，多可转化为 in order that/so that引导的状语从句；为强调目的，可用 in order to/so as to 。可作定语，起修饰或限定作用，可转化为定语从句。作业布置：复习本课所学语法。
