1、Art world一、 教学目标能理解并运用原因壮语从句二 教学重点：原因壮语从句三，交流展示Since与 as引导的原因壮语从句（1）我们也可以用Since 与as引导原因状语从句。如：Since you are free ,you had better tidy your bedroom.既然你用空，你最好把卧室整理一下（2）Since 表达“既然，由于，因为”表示已知的，显然的理由，较为正式。常放在句首。如：Since it is late .I shall go home right now.由于时间不早啦，我得回家啦。（3）As与 since的用法大体相同，表示附带说明的是双方已知的
2、原因。如：As it is raining ,you had better take a taxi.既然在下雨，你最好乘坐出租车。友情提醒：Since 与as引导的原因状语从句最好放在句首。Because ，since 与as（1），关于Because：语气最强，表示直接原因，可以回答why提出的问题，引导表语从句，用于强调句子等，其余两者都不行。-Why didnt he come?他为什么没来？-Because he was ill.因为他生病了。（2）关于Since 与 as ：两者表示的原因都是人们已知的，即对已知事实提供理由，而不是表示直接原因。Since 比as 语气稍强，而且比a
3、s略为正式，他们引导的从句通常放在主句之前，有时也放在主句之后：Are you were not there,I left a message.由于你不在那儿，我留了个口信。Since可用来省略句，而其他两者不可以。Since so,I have nothing to say.既然如此，我无话可说。五当堂检测。I.选择填空。（ ）1.Mike was ill yesterday,_he did not go to school.A.if B.but C.so D.because（ ）2.
