单元：Unit 1 Tales of the unexplained

板块：Welcome to the unit

设计思路：

本单元的学习内容主要是关于一些世间未解之谜。作为本单元的第一课时，主要是起热身作用，将鼓励学生充分发挥他们的想象力，同时还将充分利用网络、报纸、电视新闻等多种渠道的信息让学生对后面即将要学的内容有个粗略的了解，希望借此来激发学生对将学内容的兴趣，培养学生探索发现问题的能力和英语口语表达的能力，并将学习本节课教材中出现的一些重点词汇及句型。(PPT3)

Teaching aims:

After learning this section, the students will know about some mysterious and unexplained phenomena in the world. Their ability to make full use of resources to search for the information they need and share the information they get with others will be encouraged. Meanwhile, students are expected to describe what they have known about the posters and what they are eager to know about the unexplained. Their interest in scientific mysteries should be stimulated and their ability to find solutions to problems should be cultivated. Students will be encouraged to communicate with classmates so that not only can the information and their imaginative ideas be shared but also their oral English can be improved. Besides, some useful words and expressions in this part will be taught so that the students will know how to use them.

Teaching procedures:

Step 1 Lead-in

1. Group discussion: In your opinion, what is the most beautiful thing one can experience? Why? (PPT4)

2. Warm-up questions:

●What have you known about Albert Einstein? Why was he so great? (Einstein contributed more than any other scientist to the modern vision of physical reality. His special and general theories of relativity are still regarded as the most satisfactory model of the large-scale universe that we have. He solved lots of problems mysterious to us before…)(PPT5)

●Do you want to know his opinion of the most beautiful thing one can experience? —Introduce his saying about mysteries (The most beautiful thing one can experience is mysteries. They are truly the basis of all arts and sciences .PPT.6) and lead to the topic of this unit. (So you see,mysteries are of vital importance to the world. That’s why we shall begin to learn something about them. Bb: The topic of the unit. Then what kind of attitude should we adopt towards mysteries?—Bb: show interest in…; be

curious about…; trace the causes of…; analyze…; cooperate with…; seek help from…; work intelligently and independently; find solutions to…Before we take up the unit, I have two more questions for you.)

●Have you ever heard of something not only interesting and attractive but also unexplained at all even

with the help of modern science and technology in the world? Show some pictures of them to help answer the question. ( the great pyramids in Egypt; the Bermuda Triangle; the famous Mona Lisa painting; UFOs…) (PPT7-10)

●

●Are you curious about the kind of things? (Yes. Good! You have the potential ability to be a scientist. Maybe you’ll become another Einstein, but you need to have your potentials developed. I hope I can be of some help to you today. )—Bb: potential

Step 2 Posters

1．Pair work:

●Please open your books and let’s look at page one. Read the instructions and focus on the five pictures and illustrations first. Then work in pairs to find the answer to the following questions.(PPT11-12)

(1) Do the five pictures have something in common? If so, what is it?—unexplained; no satisfactory answers; mysterious; no evidence to prove… ;

(2) Can scientists explain these phenomena?

(3) How do you feel about them?

●Think of as many expressions as possible to answer the questions above. Try to make up some sentences and read them to the class. First I will offer you some examples.ppt13—They are mysterious because no satisfactory answers have been offered to explain them so far. Though these mysteries have puzzled people for a long time, they still show great interest in them. People feel puzzled by the mysteries…

本环节旨在激发学生兴趣，培养观察分析问题能力，同时旨在鼓励开口，促进口语提高。

2. Group discussion:

●Talk about the pictures one by one. (Divide the whole class into five groups and each group is assigned a topic. Give out five pieces of paper with topics on each piece. After the discussion, the students should choose one representative for their group to report their findings about their respective topic to the class. They should report like this—show them an example: ---ppt.14 UFO stands for Unidentified Flying Objects, that is, objects, apparently moving in the sky, which we cannot identify. There are lots of reports about UFOs. Some say they are aliens visiting us in their spacecraft, and some say they are military test aircraft, while others say they do not actually exist. Since we have never seen one with our own eyes and there is no definite scientific explanation for it, we are not certain whether UFOs really exist, but we
