高三英语上册 Unit3 A good teacher 第十一课
Step 1 Revision
1 Get the Ss to retell the story on SB page 10. Use the questions in Wb Lesson 10， Ex. 1 to help them.
2 Tell the Ss that the class took some food on their picnic. Get the Ss to guess the kinds of food： chicken， oranges， tomatoes， apples， bananas， etc. Make a list on the Bb.
Step 2 Presentation
Talk about fruit and other food on the Bb (using real objects， wall charts or drawing simple pictures) in this way： I like apples a little， but I like bananas very much. I prefer bananas to apples. Explain the meaning of prefer (=like more)。
Repeat， using I like…… a little， but I like…… very much. I prefer…… to…… for other items of food.
Write down the words and sentences on the Bb.
Step 3 Drill
Point to two items of food. Get the Ss to use the structure， and words written on the Bb， like this：
T： (points to pork)
Ss： I like pork a little.
T： (points to chicken)
Ss： But I like chicken very much. I prefer chicken to pork.
After drilling the structure with several items， ask the Ss to make up true sentences about their own preferences.
Step 4 Presentation
Teach this dialogue：
A： Which do you prefer， apples or bananas?
B： I prefer apples to bananas. I think apples are more delicious than bananas.
When the Ss can grasp the structure， add another line to the dialogue：
A： I agree. /I agree with you. /I don't agree (with you)。
Step 5 Listening
SB page 11， Part 1. Speech Cassette Lesson 11. Books closed! Ask the Ss What are they talking about? and play the tape of the first dialogue. Help them to answer foreign languages and science. Tell the meaning of science in Chinese. Science refers to biology， chemistry and physics. Note that sc makes /s/ sound (before i or e )。
Ask Which does A prefer? What about B? Then ask individual Ss， Which do you prefer， foreign languages or science? Help them to answer.
Books open. Play the tape for the Ss to listen and repeat.
Do the second dialogue in the same way.
Step 6 Practice
SB page 11， Part 2. Point out the more/less structure in the first box. Explain that this is the way of comparing things using long adjectives (usually of 3 syllables or more) and a few adjectives with 2 syllables. We can't say *difficulter or *interestinger. Explain the meaning of new words， such as useful. Tell the Ss useful = use + ful. Revise the word careful (care + ful)。
Make up some sentences from the box and get individual Ss to agree or disagree with you. Then get Ss to make up the sentences. Finally， Ss can work in pairs， making up sentences for their partners to agree or disagree.
Step 7 Practice
SB page 11， Part 3. Call out a student and demonstrate the first dialogue with him/her in front of the class. If you think the Ss can manage to learn to use much at this stage， get them to practise dialogues like the first one in Part 3 in pairs， using the substitute words in the box.
Get two pairs to act out their dialogues.
Step 8 Workbook
Wb Lesson 11. Choose the exercises that suit the needs of your Ss.
In Ex. 1， Ss must make sure that the answer they choose fits the words of the sentence. For instance， in the first sentence， the word than tells us that the answer is B (more difficult than)。 The answers for Ex.
1 are： 1 B， 2 C， 3 B， 4 A， 5 B， 6 C.
Ex. 2 provides more oral and written practice of the target structures.
Ex. 3 is quite difficult. Do this exercise if time permits. The Ss need to pay close attention to the words around the blanks and to ensure that their answers make sense. The answers for Ex. 3 are： A： as; B： more， more; C： agree， art， as， more; D： with， more， more; B： more， foreign， foreign， more; A： language， as.
