第9题：
What are the three different views on grammar teaching?
The first view is that teaching grammar entails the formal explanation of grammar rules. While learners who receive a great deal of grammatical explanation will end up knowing quite a lot about the language, they will not necessarily be able to put the language to communicative effect. The second view is that teaching grammar is basically a matter of providing learners with practice in mastering common grammatical patterns through a process of analogy rather than explanation. The learners may become fluent in the structures they have been taught, but may not be able to use them appropriately in genuine communication outside the classroom. The third view is that teaching grammar is a matter of giving students the opportunity to use English in a variety of realistic situations. The disadvantage is that learners will not be able to provide explanations of the grammatical rules of the target language.
