论文作者:不详    论文来源:不详    论文栏目:教案论文    收藏本页

一、教法建议

【抛砖引玉】

本单元围绕海洋知识这一题材,让同学们通过阅读“The Sea”“Salt Lakes of the World”和“Life in the Oceans”来了解有关海洋及海洋生物的知识。

单元双基学习目标

Ⅰ. 词汇学习

四会单词和词组:sailor , do well , make up one’s mind , bathe , time ( vt .) , spring , beg , beg one’s pardon , captain , depth , merely , huge , construction

   三会单词和词组:seaside , beach , dive , navy , drown , come up , vast , surface , solid , various , variety , float , the Dead Sea , partly , on average , pole , the South Pole , huge , at a time , occur , treasure , voyage , load , cycle , kg = kilogram(me) , the Atlantic = the Atlantic Ocean

Ⅱ. 交际英语

道歉和遗憾

一般来说,中国人喜欢反复强调自己的谦意,并喜欢用“非常抱歉”、“深表歉意”等表示程度倾向的语句,而英美人士则不同,对于因客观原因而造成的过失或差错,则不必主动工过分向对方表示歉意。如一定要向对方道歉,说声 sorry 即可,一般不用 very , terribly , truly 等表示程度的词。因为在美国,过分的道歉或自责反而显得不太诚恳,令人感到虚假或另有用心。

   Some useful expressions:

    1 . Sorry / Pardon / I‘m sorry .

    2 . I’m sorry for/about…

    3 . I‘m sorry to do sth . / I’m sorry to have done sth…

    4 . Excuse me  ( for… )

    5 . be afraid that…

    6 . What a pity/shame !

    7 . It‘s a pity that…

    8. That’s all right . /It doesn‘t matter . /That’s nothing .

9 . That‘s OK . /It’s quite all right . /Never mind . /No trouble at all . / That‘s not your fault .

交际示范:

    ( A is late for a birthday party )  .

    A : Come in , Mr Smith . Nice to see you .

    B : Nice to see you too . I’m very sorry to be late .  ( I‘m sorry to have kept you waiting .  )

    A : It doesn’t matter . We‘re glad you could come .

    B : I didn’t quite remember the number of your house , so it took me a long time to find your house .

    A : I‘m sorry that I didn’t make myself clear .

    B : Oh , that‘s nothing .
