Unit2Myfavoritesubjectisscience（第2课时）Howmanysubjectsdoyouhavetoday?Seven.Whatarethey?TheyareChinese/math/English...2a.Listenandputtheconversationinorder.2314语法重点一：WhydoyoulikeP.E.？你为什么喜欢体育？

why作疑问副词，意为“为什么”。用于询问原因。句子结构是why+一般疑问句？通常用because...来回答。如：---Whyishelatetoday?---Becausehegetsuplate.---Whydoesshelikeart?---Becauseit’srelaxing.语法重点二：Becauseit’sfun.因为它很有趣。（1）

because是从属连词，引导原因状语从句。在汉语中“因为”和“所以”一定要同时使用，但是，在英语中，二者只能用其一，即有了because,就不能用so;用了so,就不能用because。如：BecauseMathisinteresting,Ilikeit.=Mathisinteresting,soIlikeit.（2）fun此处作形容词，意为“有趣的”。如：Weallthinkpandasarefun.2b.Listenandmatchthesubjectsyou
