pep六年級下冊英語第三單元復習要點歸納
(4)一般過去時態由動詞的過去式表示。大多數動詞的過去式是在動詞原形后加上ed構成。這類動詞稱為規則動詞。
1) 一般情況下在詞尾直接加ed。 如:play― played work― worked
2) 以e結尾的動詞只加d. 如:like--- liked love― loved
3) 以輔音字母+y結尾的動詞,變y為i,再加ed. 如:study― studied carry― carried
4) 以重讀閉音節結尾的動詞,如果末尾只有一個輔音字母,要雙寫最后這個輔音字母,再加ed. 如:stop― stopped
(5)--ed的讀音規則如下:
1) 在清輔音后面讀[t].
2) 在濁輔音或元音后讀[d].
3) 在[t] 和[d] 后讀[id].
(6)不以ed 結尾的過去式,稱為不規則動詞。
一般過去時態的“三變”技巧
一變:肯定句變為否定句h
【技巧1】當句中含有情態動詞或助動詞could,would,should等時,可直接在其后面加not構成否定句。例如:
i could get you a concert ticket. → i could not / couldn't get you a concert ticket.
【技巧2】當句中含有系動詞was,were 時,可直接在其后加not構成否定句。例如:
i was on the internet when you called me. → i was not / wasn't on the internet when you called me.
【技巧3】當句中謂語是除情態動詞、助動詞、系動詞was, were以外的動詞時,在該動詞之前加did not / didn't,動詞還原,構成否定句。例如:
the famous singer sang some chinese songs. → the famous singer did not / didn't sing any chinese songs.
二變:陳述句變為一般疑問句
【技巧1】移動詞語的位置。將was,were, could,would,should等移到句首。例如:
he could pack his things himself. → could he pack his things himself?
【技巧2】添加助動詞did。謂語是除情態動詞、助動詞、系動詞was, were以外的動詞時,在主語之前加did,動詞還原。例如:
mr li looked very old. → did mr li look very old?
三變:陳述句變為特殊疑問句
【技巧1】確定疑問詞:人who / whom,物what,地點where,時間when / what time,原因why,頻率how often,長度how long,距離how far等等。例如:
they gave the concert last night. → when did they give the concert?
【技巧2】辨認結構形式:疑問詞+情態動詞/助動詞/ was / were / did +主語+...? 例如:
the accident happened near the station. → where did the accident happen?
2、關于名詞所有格:(僅限于小學階段 's所有格的用法)
(1)表示有生命的東西的名詞末尾加's。例如:
jim's bed 吉米的床
the man's wife 那個男人的妻子
children's toys 孩子們的玩具
the fox's tail 狐貍的尾巴
(2)以-es或-s結尾的名詞末尾加"'s"。例如:
the students' books 學生們的書
teachers' day 教師節
my boss' office 我老板的辦公室
a girls' dormitory 女生宿舍
(3)表示兩者共同擁有的人或物(共有)時,只需要后一個名詞加's(或')即可。如果表示兩者各自的所屬關系(各自所有),則每個名詞詞尾都加上's(或')。例如:
