分析
This is the third perid f this unit. The emphasis f this perid will be placed n the grammar f this unit. The key grammatical structure in this unit is the predicate clause. A predicative clause is a clause that acts as a predicate in a subject-subrdinate cmpund sentence. Like bject clause and subject clause, the predicative clause is als ne f the nminal clauses. .In rder t make students understand these pints, teacher can first get students t study the usages themselves and try t make a summary accrding t the examples, and then try t put them int use t imprve the ability t use them in real situatins.
