Unit 10 It’s a nice day, isn’t it?教案

教學重點、難點分析：
教學重點：
 1.反意疑問句（tag question）也叫附加疑問句，是一種常用于口語的疑問句式，主要由“陳述句＋附加疑問”構成，附加疑問部分的動詞一般要與陳述部分的動詞相對應，附加一聞部分的主語要與陳述部分的主語相對應，如果陳述部分的主語是名詞詞組，則附加疑問部分用相應的代詞表示。
反意疑問句主要有兩類，即“陳述句＋反意附加疑問”和“陳述句＋非反意附加疑問”。這兩類又可以分為以下四種形式：
a. 肯定的陳述句＋否定的附加疑問句。
例如：that clock is slow, isn’t it?
b. 否定的陳述句＋肯定的附加疑問句。
  例如：  that clock isn’t slow, is it?
c. 肯定的陳述句＋肯定的附加疑問句。
  例如：  that clock is slow, is it?
d. 否定的陳述句＋肯定的附加疑問句。
  例如：  that clock isn’t slow, isn’t it?
前兩種形式是主要的，后兩種形式使用場合較少。
反意疑問句也可由“祈使句＋附加疑問”構成。
例如：carry this box for me, will you?
remember to buy some meat, won’t you?
2對于我們已經學過的七種時態，這里各舉兩例：
一般現在時：lily likes going shopping, doesn’t she?
they aren’t students, are they?
現在進行時：you’re going to the cinema, aren’t you?
she isn’t waiting for me, is she?
現在完成時：they have been to singapore, haven’t they?
jack hasn’t finished his homework, has he?
現在完成進行時：you have been living in beijing all these years, haven’t you?
denis hasn’t been watching tv, has she?
一般過去時：they had a good time at the party last saturday, didn’t they?
fanny didn’t go home last night, did she?
過去進行時：you were making dinner when i called, weren’t you?
she wasn’t sleeping at this time yesterday, was she?
一般將來時：we will have wonderful summer holidays, won’t we?
they won’t come back until midnight, will they?
教學難點：
關于反意疑問句的構成，有以下幾點值得注意：
a.當陳述部分的主語是everybody, everyone, someone, no one, nobody, somebody等指人的合成詞時，反意疑問句的附加部分的主語在正式語體中通常 用he。
例如：
everybody knows what he has to do, doesn’t he?
nobody wants to go there, does he?
none of the boys can do it, can he?
在非正式語體中則往往用they。
例如：
nobody phoned while i was out, did they?
everyone enjoyed the party, didn’t they?
somebody borrowed my dictionary yesterday, didn’t they?
但若陳述部分的主語是everything, anything, something, nothing等指物的合成詞時，反意疑問句的附加部分的主語只能用it。
例如：
nothing could stop them, could it?
everything is ready, isn’t it?
