e.g.: 7 p.m. News
7.30. p.m. Weather Report
7.35. p.m. Around the world
8. p.m. Documentary: Wildlife in China
2. Ask students to form sentences orally, based on the schedule I have written on the board.
e.g. Between 7 and 7.30, the News is on TV.
Between 7.30 and 7.35, the Weather is on TV.
Ask students to read ‘Programmes on Golden TV’ and complete the table. And then check.
Step 4. Presentation
1. Remind students that apart from these two, we can also use ‘before, after and until’ to talk about time.
2.Tell students to read the grammar explanations and examples at the top of page 70. And ask them to give some examples from their own li ves.
e.g. I do my homework before I have dinner.
After our English lesson, we will go to the library.
Until I started my secondary school, my mother took me to school every day.
Step 5. Practice
Tell students to read Millie’s TV schedule and complete what she says using the words. When they have finished, ask one to give one answer each. Finally, complete ‘work out the rule’.
Step 6. Production
1.Let the Ss conclude the language points if they have some problems explain them.
2.Do the exercises.
Step 7. Homework
1. Review Grammar A &B and preview Grammar C&D.
2. Finish all the exercises.
五;知识点讲解：
1. 表示时间的介词短语“from…to…”“between…and…”
from…to…表示“从某时到某时”。如：
e,g He works from nice o’clock until five o’clock. 他从九点工作到五点
between…and…意思是“在……之间，在……中间”。如：
e,g Don’t eat between two meals. 正餐之间不要吃零食。
2. 表示时间的连词“before”，“after”和“until”
before作连词，引导时间状语从句，表示“在……前”。以before引导的时间状误从句，既可以放在主句之前，也可以放在主句之后。如果从句放在主句之前，一般要用逗号把它与主句隔开。
e,g Think well before you decide. 深思熟虑以后你再作决定。
after作连词，引导时间状语从句，表示“在……之后”。以after引导的时间状语从句，既可以放在主句之前，也可以放在主句之后。如果从句放在主句之前，一般要用逗号把它与主句隔开。
I found the letter long after he had gone away.
他走后很久我才发现了那封信。
until (till)作连词，引导时间状语从句，表示“到……时;直到……为止”。以until引导的时间状语从句，既可以放在主句之前，也可以放在主句之后。如果从句放在主句之前，一般要用逗号把它与主句隔开。以till引导的时间状语从句，只能放在主句之后。
①I’ll wait until he arrives and then I’ll leave. 我要等他来以后再离开。
②Go straight on until you come to a large red building.
一直往前，走到一幢高大的红色建筑物为止。
③Let’s wait until the rain stops. 咱们等雨停吧。
④The teacher kept on asking the students questions until (till) the bell rang.
老师反复向学生提问，直到下课铃响。

六，教学反思：
广宇学校初三年级英语教案
课题：9A unit 4 Grammar C and D课型：新授6
备课时间：
一 教学目标
1. To use ‘while’ and ‘as’ to talk about when things happen.
2. To use comparative and superlative adverbs.
二，教学重点：
The language points and how to use them correctly.
三，教学难点：
The language points and how to use them correctly.
四，教学过程:
Step 1. Revision
Translate some phrases by using ‘between…and…’,‘from…to…’ and ‘before, after,until’
Step 2 Presentation
Explain that ‘while’, ‘as’ mean ‘at the same time as’. We use them to talk about two or more actions that happen at the same time.(It is important to learn this topic)
Step 3 Ask and answer
Ask four students to read out the four examples on page 71 and spend more time to explain them. Ask some able ones to give their own sentences and put forward their own questions.
Step 4. Presentation
Explain the context of the exercise at the top of page 72. Millie is asking Daniel about what he did last night. Ask students to read through the conversation for all over meaning and complete with ‘while’ and ‘as’.
Step 5 Act out
Students read the completed speech bubbles and the teacher divides the class into groups to role-play the conversation.
Step 6 Presentation
Give students some examples using adjectives comparatives and superlatives
Remind them most adverbs ends with -ly: carefully, badly, easily, seriously, late, fast, etc.. We use the same structure as when we compare adjectives.
