· 延续性与非延续性动词的定义
1.延续性动词表示能持续一段时间的动作或表示状态的词,如work,stay,live,learn,stand, lie, walk, sleep, keep, wait, watch, sing, read等。
2.非延续性动词表示短暂的动作,从开始到结束,几乎同时或在极短的时间里就完成,如come/go/leave, open/close, start/begin/finish,become,receive,die,move, borrow, buy等。
【注意】非延续性动词表示的动作极其短暂,不能持续。因此,在现在完成时肯定句中不可与表示一段时间的状语连用,应改用_____________动词。
· 延续性动词与非延续性动词的转换
①将非延续性动词转化为意思相同的延续性动词
borrow → keep(借) become → be (成为) receive → have (收到) go to sleep → sleep (睡觉)
(穿) put on→wear (认识) get to→ know (买) buy→have (感冒) catch a cold→have a cold
② 将非延续性动词转换为be+ 介词短语,如:
begin/ start → be on finish → be over go to school → be in school
join → be in+组织机构/be a member of+ 组织机构
③ 将非延续性动词转换为be+名词,如:
join the army → be a soldier go to school → be a student
④ 用be+ 形容词/副词 结构替换非延续性动词,如:
close/ open → be closed/open come back/ go back/ return → be back come here → be here
fall asleep → be asleep finish/ end → be over marry → be married die → be dead
