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__71__,　they were　like　newborn　children,　unable　to　use　this__72__tool.Yet　once　language　developed,　the　possibilities　for　human　kind’s　future__73__and　cultural　growth　increased. 
Many　linguists　believe　that　evolution　is __74__ for　our　ability　to　produce　and　use　language. They__75__ that　our　highly　evolved　brain　provides　us__76__an　innate　language　ability　not　found　in　lower__77__.　
Proponents　of　this　innateness　theory　say　that　our __78__for　language　is　inborn,　but　that　language　itself　develops　gradually,__79__a　function　of　the　growth　of　the　brain　during　childhood. Therefore　there　are　critical__80__ times　for　language　development.Current __81__of　innateness　theory　are　mixed,　however,　evidence　supporting　the　existence　of　some　innate　abilities　isundeniable.__82__,　more　and　more　schools　are　discovering　that　foreign　languages　are　best　taught　in __83__grades.
Young　children　often　can　learn　several　languages　bybeing__84__to　them,　while　adults　have　a　much　harder　time　learning　another　language　once　the__85__of　
their　first　language　have　become　firmly　fixed.
__86__some　aspects　of　language　are　undeniably　innate,　language　does　not　develop　automatically　in　a　vacuum.Children　who　have　been__87__from　other　human　beings　do　not　possess　language. This　demonstrates　that _88__with　other　human　beings　isnecessary　for　
proper　language　development. Some　linguists　believe　that　this　is　even　more　basic　to　humanlanguage__89__than　any　innate　capacities.These　theorists　view　language　as　imitative,　learned　behavior.__90__,　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.
