未知题型 People used to think that learning two languages created confusion in the mind. Far【C1】______it was thought, to get one right than bother with two. An even more extreme and【C2】______view was that learning two languages caused a kind of mental illness or dual personality. Some studies did seem to【C3】______the idea that learning two languages could be problematic; early researchers noted that bilingual people tended to have smaller vocabularies and slower access to words. But these myths and【C4】______disadvantages have now been overshadowed by a【C5】______of new research showing the【C6】______psychological benefits of learning another language.

Furthermore, it can help develop new ways of seeing and improve your first language etc. These are all quite apart from the benefits of【C19】______yourself in another culture, and of seeing your own culture from the【C20】______of another. You may well get something like a second soul from learning another language.【C1】A．worseB．betterC．beyondD．away
