Unit4 Astronomy: the science of the starsReading: How Life Began on the Earth InterpretationGood morning, ladies and gentlemen. It’s my great honor and pleasure to be here sharing my lesson with you.I have been ready to begin this representation with six parts. Analysis of the teaching material, the students, the teaching aims, the important and difficult points, the studying methods, and the teaching procedure.Part 1 Teaching MaterialThe content of my lesson is New Senior English for China Book_3__ Unit_4_. This unit is about_Astronomy: the science of the stars. By studying of this unit, we’ll enable students to know sth. about astronomy and science of the stars and develop the interest in_science and learning English.At the same time, let the students learn how to_use the noun clauses as the subject and distinguish the noun clauses as the subject and as the object. From this lesson, it starts with warming up, pre-reading, reading and comprehending part. (As we all know, reading belongs to the input during the process of the language learning. The input has great effect on output, such as speaking and writing.) Therefore, this lesson is in the important position of this unit. If the Ss can master it well, it will be helpful for them to learn the rest of this unit.Part2 Analysis of the studentsThe students in Senior High School, grade one have already learned English for years, they can speak and communicate with their friends in English. They are moderate, mature and sensitive. They are highly motivated in learning English and have the ability to learn by themselves. Furthermore, the topic of this unit is about astronomy, which is full of mystery, the students will have greater interest in learning it. However, the differences in english level among students is the biggest challenge. Therefore the teacher should provide enough background information to make them better understand the text. Therefore, I will adopt appropriate teaching methods to arouse their interest in learning.Part 3 Teaching AimsAccording to the new standard curriculum and the syllabus (新课程标准和教学大纲), and after studying the teaching material, the teaching aims are the followings: 1.Knowledge objects (语言目标：语音，词汇，语法，功能，话题)(1)The Ss can master the usage of the important words and expressions.(2)The Ss can use the noun clauses as the subject and as the object in the proper situation.(3)The Ss can understand the content of the lesson, talk about astronomy and get their own idea about protecting the earth.2.Ability objects (技能目标：听，说，读，写)(1) To develop the Ss’ abilities of listening, speaking, reading and writing(2) To guide Ss to set up effective studying strategies.(3) To improve the student’s reading ability, especially their skimming and sca nning ability.(4) To train the Ss’ abilities of studying by themselves and cooperating .3.Emotion or moral objects (情感目标：兴趣，自信，合作，爱国，国际视野) (1)By completing the task, the Ss increase their interest in astronomy and science and set up self-confidence in learning English and protect the earth in proper ways.(2)Teach the Ss to cooperate with others and cultivate the patriotic spirit and international visions, put the moral education in the language study.Part 4 the Important and Difficult PointsBased on the requirement of the syllabus. The important points are_new words and expressions in the text, such as theory, billion, violent,fundamental, give birth to etc. The difficult points are the usages of noun clauses as the subject and as the object, how to distinguish these two kinds of noun clauses.Part 5 Teaching MethodsAs is known to us all, a good teaching method requires that the teacher should help Ss develop good sense of the English language. For achieving these teaching aims, (after the analysis of the teaching material and teaching aims,) I will use the following methods according to the modern social communication teaching theories(现代社会交际教学理论) .municative Approach(交际教学法)2. Whole Language Teaching(整体语言教学法)3. Task-based Language Teaching (任务教学法)4. Total Situational Action (情景教学) a “scene —activity” teaching method , it establishes a real scene and the interaction between the teacher and the Ss. At the same time, CAI (电脑辅助教学) can provide a real situation with its sound and picture, it can develop the Ss creativity in learning English.Part 6 Teaching ProcedureStep1.Lead-in.(__10___min)1.Ask students to read the questions in warming up part, then discuss with their group members. After that ask several representatives to give their ideas.2. Ask students: Do you know any big events in the astronomy in history? If you know, can you tell us sth. about them? Are you interested in science? Do you know how earth began to form?Purpose of my design: (1) to catch Ss’ attention abou t the class/topic/passage.(2)To set up suspense/develop interest in the astronomy and the science.Step 2.

Then ask one student to say his/her guess.Now, let’s see what happened in the text./ let’s check whether it is right or not.

人教版高中英语必修3Unit4 Grammar-Subject Clause (说课)

Unit4 Grammar-Subject Clause (说课)Ladies and Gentlemen,It’s my great pleasure to have an opportunity to talk about some of my teaching ideas. My topic is Unit 4 Language Learning from Senior High English of Module 3. To make my presentation much clearer,I’ll explain my lesson plan in the following six parts: Analysis of the teaching material, the teaching methods, the studying methods, the teaching procedure, blackboard design, and comments. First, let me talk about the teaching material.Part 1 Analysis of the teaching material:(1) Status and functionThis lesson is about language. It is about the usages of the subject clause, which is the basis of the whole unit. And it also plays an important part in the exams. In order to let the students have a better understanding of this grammar, I’ll rearrange the teaching contents. During the class, I will help the students to discover the forms and the meaning of the subject clause. And then , I'll summarize the usages of the subject clause, especially the heated exam points.(2)Teaching aims:Knowledge objectives1. Enable the students to identify the subject clause.2. Help the students get a general understanding of this grammar item, including: thedefinition, position, characteristics, and structures of a subject clause. ,the usages of subjunctive mood in the subject clause..Ability objectives1. To make the students the real masters in class and develop the students' awareness of self-learning.2. To train the Ss’ communicative ability by using the subject clause.(3)Teaching important points:1. To grasp the usages of the subject clause.2. To master the heated exam points----the usage of the conjunctions, the word order ofthe clauses, the usages of it as the grammatical subject etc..(4)Teaching difficult points:1. Developing Ss’ ability of observing and analyzing information.2. Using the subject clause to write a composition.(5)Teaching aids: Multi-media computer, BlackboardPart 2 Teaching methods:Communicative Approach, Task-based language teaching.Part 3 Studying methods:1. Individual study.2.Cooperative study.Students should be good at grasping the chances of communication in English, take an active part in the class activities and do well in the cooperation with their partners. Part 4 Teaching procedurePart 5: CommentsAt the end of these periods, the students will be able to identify the subject clause and grasp the usages and the important points. They can also know how to use them to make up sentences in writing compositions. Moreover,I can improve the students' communicative ability. Meanwhile, through the class activities, the students are enabled to understand the importance of unity, cooperation, friendship and love between each other.activities intentions methods Step 1Lead in Task 1:Read and translate seven sentences on the screen and figure out the functions of the clauses.To experience the subject clauses. Pair work T-Ss checkStep 2 Discovery and summary 1.Have the students work in pairs to analyze the sentence structures and compare them . 2.Make a summary of thedefinition of the subjectclauseTo help Ss to know the forms of the subject clause and the structures.Pair work T-Ss checkStep 3 Exploring and analysis 1. Read additional sentences on the screen, and have the students underline the conjunctions and compare them. 2. Make a summary of the conjunctions that can introduce subject clauseTo help the students get a better understanding of the subjectclause so that itwill be easier for Ssto use them.Individual work T-Ss checkStep 4 Samples and correction Practice 1. Give the samples of the subject clause ,and then explain the usages of it ,stressing the important points during the teaching process. 2. Have the students do some exercises about theheated exam points, andthen help them make asummary.To help the students pay attention to the important points of the subject clauseand help them getbetter grades in theexams.Individual work T-Ss checkHowever, I think it is a little difficult for my students to grasp all the usages of the subject clause in such a short time, especially the poor students. So I can't make sure that everyone in my class can achieve the aims that I have set, in particular the writing task. There is no doubt that they need to practice more to consolidate this grammar.That’s all. Thank you very much!。

答案：
文章用海明威的例子来说明一个问题：当生活给你一个打击，你就借势
向前。

1. D 通读全文可知“不应该把所有的坏运气都看作坏事”(它也许是推动你前
进的一次机会或者动力)。

根据此意需要选 D项
2. D 根据文章最后一段可以得到提示：“When life gives you a kick, let it kick
you forwards!” 当生活给你一个打击，你就借势向前。

3. A 海明威通过这个“厄运”学到了一些东西。

学到了 / 学会了要用learn表达。

4. B 从第四段最后一句“Hemingway did rewrite the stories and eventually
became a world-famous writer.”可知在他丢书稿的时候他尚未成名，所以
是在努力(struggling)当中。

5. C 即将出版的书稿丢了，这对尚未成名的海明威来说不啻是一次灾难(disaster)。

6. C 这几个月的辛勤劳动的成果就这样付诸东流了(simply wasted)。

(weak)部分。

weak与the best相对。

9. B 朋友鼓励他要乐观(optimism)，要有自信心(confidence)，而confidence
与optimism并列，表达相近的意思。

10. C 从前一句的“Don’t pray for fewer problems; pray for more ability.”可知不
是要祈祷问题会减少，而应该去起到自己获得更大的能力。

那么，下一
句：不是祈祷少一些挑战，而应该祈祷自己具备更高的智慧 (greater
wisdom)来应对这些挑战。

不是寻找一个简单的解决途径，而是要可能
的最佳的方法。
