    What is the major difference between deductive learning of grammar and inductive learning of grammar?

    正确答案： A basic distinction in learning theory is between deductive learning and inductive learning. Deductive learning is an approach to language teaching in which learners are taught rules and given specific information about a language. They then apply these rules when they use the language. In contrast, in inductive learning learners are not taught grammatical or other types of rules directly but are left to discover or induce rules from their experience of using the language. The former is explicit teaching of grammar while the latter is implicit.

    What’s the difference between casual listening and focused listening?

    正确答案： If we listen with no particular purpose in mind, and often without much concentration, the kind of listening is called casual listening. Usually we do not listen very closely, unless we hear something that particularly interests us, and afterwards we may not remember much of what we heard. However if we listen for a particular purpose, to find information we need to know, the kind of listening is called focused listening. In these situations we listen much more closely; but we do not listen to everything we hear with equal concentration—we listen for the most important points or for particular information. Usually we know beforehand what we are listening for.
