content: grammar
(三)teaching aims：
1. to learn some new words.
2. to learn the use of the present perfect tense.
important and difficult points:
短暫性動詞和延續性動詞的區別、用法及轉換
teaching procedures:
step1. check the homework.
step2 .add some irregular verbs.
become—became---become  choose—chose—chosen cost—cost—cost  drink—drank—drunk feel—felt—felt give—gave—given  grow—grew—grown  hurt---hurt—hurt lend---lent---lent   pay---paid---paid   meet---met---met
step3. explain the grammar.
短暫性動詞（瞬間性動詞）由于動作不能延續，故不能與表示一段時間的狀語for…或since…連用。常見的短暫性動詞有：go, come, borrow, open, close, stop, join, marry, die, become, arrive, reach, begin, start, leave, receive, buy, put, lose，lend, find, finish等。
如果表達上述短暫性動詞“繼續多長時間”的概念，則需要改用與之相應的表示狀態的系表結構，這種系表結構多為 be+ 形容詞（副詞、介詞短語等）構成，試比較：
誤：he has come here for seven years.
正：he has been here for seven years.    he came here seven years ago.
誤：this factory has opened for several years.
正：this factory has been open for several years.(open是形容詞，表示“開”的狀態。)
