新目標八年級英語下冊Unit9 Section A導(dǎo)學(xué)案
(四)延續(xù)性動詞和非延續(xù)性動詞
1)延續(xù)性動詞:動作可持續(xù)一段時間,可和for, since等表示一段時間的時間狀語連用。
2)非延續(xù)性動詞:動作不能持久,一瞬間就結(jié)束,不能延續(xù),或表示一次性動作,也叫短暫性動詞、瞬間動詞、終止性動詞。不能和表示一段時間的時間狀語連用。常見這類動詞有 come, go, leave, begin, start, arrive, reach, see, die, join, get up, borrow, lend, buy, finish, end, become, hear from等。
*判斷正誤如有錯誤并改正:
he has come back. ( )___________________________________
he has come back for 3 days. ( )___________________________________
i have borrowed the book. ( )___________________________________
i have borrowed the book since last week. ( )____________________________
i have got up for an hour. ( )____________________________
he has died for 10 years. ( )____________________________
3)非延續(xù)性動詞的否定式已成為一種可延續(xù)性狀態(tài),可以和for, since等表示一段時間的時間狀語連用。
i haven’t seen him for a long time. / since he left.
i haven’t heard from him for half a year.
i haven’t borrowed books for two months.
4) 非延續(xù)性v. 可以轉(zhuǎn)換為延續(xù)性v.,有以下幾種情況:
a) 用相應(yīng)的延續(xù)性動詞
buy—have; borrow—keep/have; put on—wear; catch(get) a cold—have a cold; come/go/become—be
b) 轉(zhuǎn)換成“be + n.”形式
join the party—be a party member join the army—be a soldier
go to school—be a student
c) 轉(zhuǎn)換成“be + adj./adv.”形式
die—be dead; finish—be over; begin—be on; leave—be away; fall asleep—be asleep; wake up—be awake; get up—be up; close—be closed; open—be open
d) 轉(zhuǎn)換成“be + 介詞短”語形式
go to school—be in school; join the army—be in the army
5)practice:
