Step . IV . Dialogue

1. cabbage seed: " seed " here is used as an uncountable noun.

(But: I love pumpkin seeds. Can you buy some more for me? )

2. so that = in order that

3. stop the soil (from) getting too dry

stop sb, (from) doing sth. 阻止某人做某事

e.g. The heavy rain stopped us (from) going out.

4. like you feed chickens = as you feed chickens

(Then let the Ss practise the dialogue in pairs. Finally ask some pairs to act it out in front of the class.)

Step V. Practice

T: In the adverbial clause introduced by " so that “, the modal verbs " may, can, might, could " are often used, Look at examples, (Show the following on the screen.)

They set out early so that they might arrive in time.

= They set out early to arrive in time , ( 此時(shí)主從句主語(yǔ)相同）

Speak clearly so that everybody can

understand you ( 主從句主語(yǔ)不一致時(shí)不用不定式)

Water the plants so that they will grow (different subject)

Water the plants to make them grow (same subject)

Put the little plants in the shade so that the sun won' t burn them. (different subject ) )
