Let the Ss do Activity 2. A few minutes later, check the answers.
...
T: Now let’s come to Activity 3. Read the two sentences quickly. The two sentences use the negative forms of in order to and so as to. We should pay attention to the position of not in the two phrases. Now complete the five sentences according to the meaning of each sentence.
A few minutes later, check the answers with the whole class. Then deal with Ex. 1 in WORKBOOK on page 73.
Step IV Function
Ask the Ss to read the sentences and translate them into Chinese. Let the Ss understand the meanings of so, as a result and as a result of. Then ask them to read the sentences again and pay attention to the differences in usage of the three. Especially as a result and as a result of. At last finish the six sentences.
…
T: Very good. Now let’s compare the usages of them. Look at the following on the screen:
(cause) + as a result + (result)
(result) + as a result of + (cause)
(cause) + so + (result)
as a result + clause
so + clause
as a result of +n. / pronoun. / doing

S: Yes.
Then deal with Ex. 4 in WORKBOOK on page 73.
Step V Grammar 2
Ask the Ss to read the six sentences in Activity 1 on page 16 and then answer the two questions.
...
T: Then what’s the difference between so and such?
Ss: so + adj. / adv.
such + a / an + adj. + noun
T: Very good! Any other differences?
Ss: No.
T: OK. I’ll tell you. When the adjectives are many, much, few, little etc. we should use so. Besides, we should also pay attention to another use of so and such.
so + adj. + a / an + noun = such + a / an + adj. + noun
For example, such an interesting book. We can also express it like this: so interesting a book.
So far, do you know the usages of so and such?
S: Yes.

A few minutes later, check the answers to the six sentences and then turn to page 73, deal with Ex. 2.
