非延续性性动词转延续性动词的规律
1、用意义相同或相近的延续性动词替代.如：
borrow→keep, buy→have, become →be, get up→be up, fall ill →be ill,put on→ wear, come here →be here, go there →be there,get to know → know,go (get) out →be out,fall asleep→be asleep, get/catch a cold→have a cold
2、用“be+形容词”替代.如：
die→be dead, open→be open,end/finish → be over,
3、用“be+介词或副词”替代.如：
begin/start→be on,join→be in/be a member of, leave→be away, come→be in/here, go→be away/out, reach/arrive/get to→stay/be in
