Intelligence-Nature　or　Nurture?

1） 有人认为智力是天生的；

2） 也有人认为智力是环境决定的；

3） 如何更好地发展智力。

Are　some　people　born　clever,　and　others　born　stupid?　Or　is　intelligence　developed　by　our　environment　or　experience?　Strangely　enough,　the　answer　to　both　questions　is　yes.

On　the　one　hand,　if　we　take　two　people　at　random　from　the　crowd,　it　is　very　likely　that　their　degrees　of　intelligence　will　be　completely　different.　However,　if　we　take　two　identical　twins,　chances　are　that　they　will　be　as　intelligent　as　each　other.　Therefore,　a　conclusion　can　be　drawn　that　intelligence　is　to　some　extent　something　we　are　born　with.　The　closer　the　blood　relationship　between　two　people,　the　closer　they　are　likely　to　be　in　intelligence.

On　the　other　hand,　though,　if　we　put　two　identical　twins　in　different　environments,　for　example,　we　might　send　one　to　university　and　the　other　to　a　factory　where　the　work　is　boring,　we　would　find　differences　in　their　intelligence　several　years　later,　which　indicates　that　environment　does　play　a　crucial　role　in　our　intelligence.

Just　as　every　coin　has　two　sides,　our　intelligence　is　partly　born　and　partly　developed.　The　sure　way　to　develop　our　intelligence　is　intelligent　parents　as　well　as　a　good　environment.
