Unit 4 Exploing plants Part 1: Teaching Design

(第一部分：教学设计) Period 1: A sample lesson plan for reading (HOW LIFE BEGAN ON THE EARTH) Aims To develop the students’ reading ability

To learn something about astronomy Procedures I. Warming up by learning vocabulary

Good morning, class! Today, w are going to take Unit 4 Astronomy: the science of the stars. Before we read the text, let’s turn to page 99 and get familiarized with the vocabulary first. Pay attention to the making of the word. Study the prefixes, roots and suffixes in the words.

Astronaut Yang Liwei II. Pre-reading 1. Looking and saying

Have you ever wondered how the universe began? Well I'm sure you may have many answers to this question, but I have one that perhaps, you may not have heard of yet. I will be giving you my theory on this subject. Now look at the screen and listen to me telling you something exciting. 科学家透露：宇宙可能有两个

我们的宇宙和一个"隐藏的"宇宙共同"镶嵌"在"五维空间"中。在我们的宇宙早期，这两个宇宙发生了一次相撞事故，相撞产生的能量生成了我们宇宙中的物质和能量。

2. Talking and sharing Do you know how the universe began? In the 1920s in California, astronomer Edwin Hubble observed distant galaxies using an extremely powerful telescope. He made two mind-boggling(unbelievable) discoveries.

First, Hubble figured out that the Milky Way isn’t the only galaxy. He realized that faint, cloud-like objects in the night sky are actually other galaxies far, far away. The Milky Way is just one of billions of galaxies.

Second, Hubble discovered that the galaxies are constantly moving away from each other. In other words, the universe is expanding. The biggest thing that we know about is getting bigger all the time.

A few years later, Belgian astronomer Georges Lemaître used Hubble‘s amazing discoveries to suggest an answer to a big astronomy question: “How did the universe begin?”

III. Reading 1. Listening and reading aloud

Now please listen to the recording and then read the text aloud. Pay attention to how the native speaker is reading along and where the pauses are within each sentence. I will play the tape twice and you shall read aloud twice, too.

2.

Reading and underlining Next you are to read and underline all the useful expressions or collocations in the passage. Copy them into your notebook after class as homework.3. Reading and understanding difficult sentences

Skim the text and identify the difficult sentences of each paragraph. You may put your hand up if you have any questions.

4. Reading and transferring information

Read the text again to complete the table below,

HOW LIFE BEGAN ON THE EARTH What was the earth like after

the “Big Bang”?

Why was the earth different?

How was life developed on

earth? What did small clever animals

do?

5.

Reading and translating

As you have read the text times, you can surely put it into Chinese. Wang Hongqin, will you be the first to have a try, of putting the first paragraph into Chinese. IV. Closing down Closing down by doing exercises To end the lesson you are to do the comprehending exercises 2 and 3 on pages 26 and 27.

Closing down by having a discussion—How Did the Universe Begin? There are only three possible answers to this question.

1．It was created by something larger than itself since the first law of thermodynamics(热力学) says that energy cannot be created, only changed. The universe had to be created by something outside itself, because of the same law. We also know that man could not have created it.

2．It was begun by chance (or accident); or 3．The answer is not sure.
