听力原文：M: Hey, Lily. Seems you got some sun this vocation.
W: Yeah, you may say so. I spent the vocation at the beach.
M: Oh, yeah？ That's great! Where did you stay？
W: Some friends of mine live out there. And they invited me for as long as I wanted to stay.
M: So, what are you doing back here already？
W: Oh, I have a research project waiting for me. And I just couldn't do any serious studying at the beach.
M: I guess so. Well, what did you do out there？ I mean, besides lie out in the sun, obviously.
W: I walked my friend's dogs along the beach and I played some volleyball. You know, I never realize how hard it is to run on sand. I couldn't even get through a whole game before I had to sit down. It's much easier to run on the wet sand near the water.
M: Did you go swimming？
W: I wanted to, but they said the water wasn't warm enough for that until a couple of months from then on. So I just wetted in up to my knees.
M: It all sounds so relaxing. I wish I could get away to the beach like that.
W: Of course you could. Don't tell me you spent the vocation in the library again.

From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us. When humans first【B1】, they were like newborn children, unable to use this【B2】tool. Yet once language developed, the possibilities for human kind's future【B3】and cultural growth increased.
Many linguists believe that evolution is【B4】for our ability to produce and use language. They【B5】that our highly evolved brain provides us【B6】an innate language ability not found in lower【B7】. Proponents of this innateness theory say that our【B8】for language is inborn, but that language itself develops gradually,【B9】a function of the growth of the brain during childhood. Therefore there are critical【B10】times for language development.
Current【B11】of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable.【B12】, more and more schools are discovering that foreign languages are best taught in【B13】grades. Young children often can learn several languages by being【B14】to them, while adults have a much harder time learning another language once the【B15】of their first language have become firmly fixed.
【B16】some aspects of language are undeniably innate, language does not develop automatically in a vacuum. Children who have been【B17】from other human beings do not possess language. This demonstrates that【B18】with other human beings is necessary for proper language development. Some linguists believe that this is even more basic to human language【B19】than any innate capacities. These theorists view language as imitative, learned behavior.【B20】, children learn language from their parents by imitating them. Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.
