青花瓷又称白地青花瓷，是中华陶瓷烧制工艺的珍品。周杰伦的《青花瓷》发表于2007年，曲调中国风，歌词更是紧扣青花瓷主题，描绘出一幅烟雨朦胧的江南水墨山水。罗艺恒(LaurenceLarson)翻唱的《青花瓷》给人一种不一样的视听感觉，别有一番异国风味。

aslongas

“长达……之久”，引导比较状语从句。【拓展】

(1)aslongas还可以引导条件状语从句，意为“只要”。引导条件状语从句的短语还有：incase如果；万一onconditionthat只要provided/providingthat如果；条件是

aslongasyouhaveadream，keeptryingandyou’llmakeit,too.“世上无难事，只怕有心人”，只要你有梦想，并坚持尝试，你也会成功的。【名师提醒】aslongas和solongas表示“只要”时没有区别，可以相互替换；aslongas表示“与……一样长”时，多用于肯定句；否定句多用solongas。

aswellas在句中用作介词。【拓展】

(1)aswellas常用来连接两个并列的成分，意为“也，还”。(2)aswellas用来表示同级比较，意为“一样好”。(3)aswellas用作介词相当于besides，inadditionto，意思为“除……之外”。Ateachershouldentertainaswellasteach.教师不仅要教书，也要引起学生兴趣。Youlookaswellasyoudidtenyearsago.你的身体看起来还和十年前一样好。Aswellasbreakinghisleg，hehurthisarm.他不但摔断了腿，而且还伤了胳膊。【名师提醒】

当aswellas连接两个主语时，谓语动词的形式要与前面的主语保持一致。Hischildrenaswellashiswifewereinvitedtotheparty.不但他的太太，而且连他的孩子们都被邀请去参加聚会。单句语法填空①Yourwifeaswellasyou____________(be)friendlytome.②Tom，aswellasJaneandRose，____________(be)goingtothefarmonfoot.补全句子③Heplaystheguitar__________________.他的吉他弹得和你一样好。④___________________________________fivecoursemeals,theydranksevenbottlesofwine.除了五道菜外，他们还喝了七瓶酒。⑤Shecanplaytennis____________________.她也会打篮球，也会打网球。
