2015年成人英语三级考试完形填空强化试题及答案（2）

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　1　,　they　were　like　newborn　children,　 unable　to　use　this　2　tool.Yet　once　language　developed,　the　possibilities　for　human　kind?s　future 　3　and　cultural　growth　increased.

Many　linguists　believe　that　evolution　is　4　fo

r　our　ability　to　produce　and　 use　language.They　5　that　our　highly　evolved　brain　provides　us　6　an　innate　language　 ability　not　found　in　lower　7　.　Proponents　of　this　innateness　theory　say　that　our　8　 for　language　is　inborn,　but　that　language　itself　develops　gradually,　9　a　function　of　 the　growth　of　the　brain　during　childhood.Therefore　there　are　critical　10　times　for　language　development.

Current　11　of　innateness　theory　are　mixed,　however,　evidence　supporting　 the　existence　of　some　innate　abilities　is　undeniable.　12　,　more　and　more　schools　 are　discovering　that　foreign　languages　are　best　taught　in　13　grades.Young　children　often　 can　learn　several　languages　by　being　14　to　them,　while　adults　have　a　much　harder　time　learning　another　language　once　the　15　of　their　first　language　have　become　firmly　fixed.

16　some　aspects　of　language　are　undeniably　innate,　language　does　not　develop　 automatically　in　a　vacuum.Children　who　have　been　17　from　other　human　beings　do　 not　possess　language.This　demonstrates　that　18　with　other　human　beings　isnecessary　 for　proper　language　development.Some　linguists　believe　that　this　is　even　more　basic　 to　human　language　19　than　any　innate　capacities.These　theorists　view　language　as　imitative,　 learned　behavior.　20　,　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.
