《A butterfly》主要教学过程及板书设计

教学过程

Step1 Warming-up and lead-in

After greeting the students, I will play the song “The bear”, whose lyrics use the simple past tense, to the students. I will write down a segment of the lyrics on the blackboard and review the past form of some verbs, such as “look-looked”, “meet-met” and “say-said”, with the whole class.

Step2 Presentation

I will enjoy the strip pictures of butterfly growth with the whole class to introduce the simple past tense. I will ask students questions while watching the pictures. The questions are: “what was the color of the egg?”, “what did a caterpillar eat?” and “how long did the caterpillar live in the small cocoon?” By orders of strip pictures, the growth a butterfly is showed clearly, and time sequences are showed by “the first”, “then” and “finally”.

As the students answer these questions, answers are written down on the blackboard. I will invite students to work out the rule of the simple past tense. Simple past tense is usually used to talk about a completed action or state that occurred in the past, and to form this tense, one needs to add -ed to the end of a regular verb and remember the past forms of some irregular verbs.

Step3 Practice

1. Conversion task: students are required to converse the following simple present tense into simple past tense to better understand the new structure:

I usually eat an egg for breakfast.

I _____ an egg for breakfast yesterday morning.

People often live in houses.

John _____ in the small village for about two years.

Do you come to your grandma’s twice a week?

He _____ to see his grandma last week.

There are three people in my family.

There _____ many butterflies here 5 years ago.

2. Translation task: students are expected to translate the following Chinese into the corresponding English.

我妹妹早餐吃了一个橙子和一片面包。

约翰之前和他妈妈去逛了百货商场。

我上周买了一个新的文具盒。

Step4 Production

1. Group discussion: divide the whole class into groups of 6 and require them to describe the growth of a tree, at the same time, draw it into strip pictures. Three groups will be asked to have a presentation.

Filling blanks: students try to fill in the blanks below independently:

It _____ a small seed. Then it _____ a sapling after two weeks. Finally it _____ tall and _____ a large tree. There _____ so many big trees.

Step5 Summary and homework

Summary: invite two students to retell the growth of a butterfly with the help of strip pictures.

Homework: ask students to select pictures of their childhood and make a comparison between the present selves and the old selves.

先让外语学习者接触包含语法规则的真实上下文，通过学习大量例句，使学生形成一定程度的感性认识，进而对材料进行加工，最后再总结归纳出语法规则。
