北师大版高一英语必修一教案第单元第课(整理版)

本课流程

Reading部分说课稿 Unit one lifestyles

Lesson one a perfect day?

第一个板块——教材分析

※第一环节——说教材。作为高中英语开篇单元，

本单元的话题是lifestyles,主题与生活紧密贴切。

那么作为本单元的第一课A Perfect Day?其重要

性不言而喻。本课的知识点是大部分学生乐于学

习和接受的，相信他们对本课的学习充满期待。

第二环节——说教学目标。

新英语课程标准指出，基础教育阶段英语课程的总体目标是培养学生的综合语言运用能力。而综合语言运用能力又以学生语言技能、语言知识、情感态度、学习策略和文化意识五个方面的综合素养为基础。

1)Knowledge Objects

2) a. To discuss favorite TV programs and daily activities

3) b. To revise Present Simple and Present Continuous.

4) c. To read two texts in order to check predictions.

5) d. To read two texts for specific information.

6) Ability Objects

7) a. Enable the students to learn how to scan and skim.

8) b. Enable the students to guess the meaning of the words from the context.

9) c. Enable the students to understand the importance of reading.

10)d. Enable the students to read a lot after class

11)Emotion Objects

12)a.To discuss the healthy lifestyles and improve the awareness of cross-cultural

communication.

13)b. Let the students know and respect different ways of lifestyles of people and

let them know how to plan her/his future after reading the texts.

在仔细研究教材和分析学生的心理和生理特点的基础上，我认为本课的重难点有：Teaching Important Points:

1) Help the students to master the key words associated with lifestyles.

2) Talk about people’s different lifestyles.

3) Get the general idea about two passages.

Teaching Difficult Points:

1) How to grasp the key information of an article in the limited time.

2) Train the students to use the third person in Present Simple to complete sentences correctly.

3) The omit of “be” in Present Continuous.

第二个板块——教学与学法分析。

第一环节——说教法。在教学过程中，不仅要使学生“知其然”，还要使学生“知其所以然”。我们在以师生既为主体又为客体的原则下，展现获取理论知识、解决实际问题的思维过程。

基于本课题的特点，我主要采用了以下的教学方法

1. 直观演示法：利用图片等手段进行直观演示，激发学生的学习兴趣，活跃课堂气氛，促进学生对知识的掌握。

2. 活动探究法：引导学生通过创设情景等活动形式获取知识，以学生为主体，使学生的独立探索性得到了充分的发挥，培养学生的自觉能力、思维能力、活动组织能力。

3. 集体讨论法：针对学生提出的问题，组织学生进行集体和分组语境讨论，促使学生在学习中解决问题，培养学生团结协作的精神。

第二环节——说学法。我们常说：“现代的文盲不是不懂字的人，而是没有掌握学习方法的人”，因而，我在教学过程中特别重视学法的指导。让学生从机械的“学答”向“学问”转

变，从“学会”向“会学”转变，成为学习的真正的主人。这节课在指导学生的学习方法和培养学生的学习能力方面主要采取以下方法：思考评价法、分析归纳法、自主探究法、总结反思法。

第三个模块——教学程序分析。

在这节课的教学过程中，我注重突出重点，条理清晰，紧凑合理，各项活动的安排也注重互动、交流，最大限度的调动学生参与课堂的积极性、主动性。主要有：

Step1.Lead-in:

教材开头的情景设置导入新课，根据教材的特点，学生的实际、教师的特长，以及教学设备的情况，我选择了多媒体的教学手段。这些教学手段的运用可以使抽象的知识具体化，枯燥的知识生动化，乏味的知识兴趣华。

1. Begin the class with showing some pictures about different life styles.

2. Ask the students: What kind of life style do you think the people in the pictures have? and what’s your favorite lifestyle and why?

3. Tell the students we are going to learn about A perfect Day.

Step2. Warming –up: TV Spider gram: what are your favorite programs and why? Step3. Learning the new words:

Step4.Understanding the texts and collecting information:

掌握阅读技巧，提高于都速度：

The first article: A Couch Potato

1. Listen to the tape, and during the listening, please underline the new words and repeat after the tape silently.

2. Read again and answer the question: What does a couch potato refer to?

3. Collect the information about Brian’s “a perfect day” and describe his life. The second article: A Workaholic

1. Play the tape and ask the students to underline the new words and repeat after the tape silently.

2. Read again and answer the question: What is workaholic?

3. Please read the text about Bob and describe his busy life.

Step5. Read and find the differences

训练学生纵横分析问题的角度：

Read these two articles and find the differences between Brian’life and Bob’s life. Step6.Grammar exercises about Present Simple and present Continuous

掌握重要语法知识点：

First turn to page 9 ,analysis and explain Present Simple and Present Continuous .Then do the exercise 8 and 9.

Step7. Discussion

调动课堂积极性：

1. Which one is healthier?

2. What can Bob or Brian do to improve their lifestyle?

Step8. Homework:

训练写作，同时巩固所学，将课内的学习延伸到课外：

Write a composition “My Perfect Day”

Words:100 words or so

Suppose you can design your a day freely what is your perfect day like?

Step9. Blackboard Design

我比较注重直观地、系统的板书设计，并及时地体现教材中的知识点，以便于学生能够理解掌握。我的板书设计是：

模块3 U7 L1 1 The Spirit of Explorers Viking Voyages to America The Vikings were the first Europeans to reach America. They achieved this long before Columbus ever set sail. The Vikings were a group of people whose ancestors came from Scandinavia. They controlled the seas and coasts of Northern Europe between the 8th and 10th centuries AD. By around 900 AD, there were many places in Northern Europe where the Vikings chose to live. In 982 AD, when a man called Eric the Red decided to set sail further west, there were as many as 10,000 Vikings living in Iceland. According to the old stories of Iceland and Norway, Eric the Red was forced to leave Iceland because he had committed a murder, for which he got into trouble. Eric reached Greenland and discovered that people could live in the place where he landed. He returned to Iceland and told people there about Greenland. He persuaded some people to go back with him to Greenland. Eric set sail once again, this time with 25 ships, of which only 14 made it to Greenland. Not long after Eric the Red had landed in Greenland, a man called Biarni set sail from Iceland in search of Eric's party. Biarni was hoping to join his father who was with Eric, but he was blown off course and found himself in an unknown land, from where he eventually reached Greenland. In the year 1002, when Eric the Red's son Leif was planning a trip further west, Biarni was the man with whom Leif discussed his plans. Leif followed Biarni's directions and sailed to what is believed to be the coast of present-day Canada. He then sailed further south to an island which is now known as Newfoundland. We know about Eric the Red and Leif's deeds through stories which were written down centuries later in Norway and Iceland. They are the first records we have of Europeans sailing to the Americas. U7 L3 3 The Sea World UNDER WATER WORLD The Best place to See Sea Creatures Polar World We have polar bears and a real iceberg too! You can only see a small part of it above the water. It's three times as big underwater. Watch the acrobatic seals at feeding time. Meet our less energetic but more friendly penguins. You'll love them! Ocean Floor See some of the most beautiful coral and the most unusual fish in the world. Watch some fish “flying” through the water. They are less colourful than some other fish but they move beautifully. Sea Theatre See our intelligent dolphins. There are fantastic shows every two hours. Discovery Pool Especially for younger children. They can touch crabs and other smaller creatures. They can be educated about daily life on the beach in this exciting area. Virtual Reality Voyage Our most up-to-date attraction. Come with us on a “virtual reality” trip to the ocean floor and see some of the strangest fish in the world.
