6、)Learning only appears to be without awareness,but in fact learners are aware of what they are learning.The extent of learners explicit L2 knowledge.Explicit knowledge:the L2 knowledge of which a learner is aware and can verbalize on request.Implicit knowledge:the L2 knowledge of which a learner is

13、l and variational axis.A number of processing constraints will be proposed to account for the process along the developmental axis.the canonical order strategy (prevent learners from interrupting the basic subject-verb-object word order)initialization/finalization strategy (move the elements at the

16、 because your existing knowledge is not enough?2.What communication strategies can we resort to when we are in the above situation?Give some lists.Not sure about the usage of a word or phrase:1.avoidance (avoid problematic items)My mother makes me to give him some money.makes asks Communication Stra

17、tegiesNot knowing a word in target language:1.Borrow a word from L1e.g.I want to have some confiture.(=fruit jam)果酱，法语词2.Use another target-language that is approximate in meaninge.g.worm-silkworm 3.Paraphrase the meaning of the worde.g.fang(蛇、犬的)尖牙-sharp teeth4.Construct an entirely new worde.g.art
