My brother joined the army two years ago. .若保留for+时间段,since+时间点/从句, 或用在 how long 句型中,则需将终止性动词改为相应的状态动词或延续性动词 The film started two hours agoThe film has been on for two hours常见短暂性动词与延续性动词的转换. be 型1. go there - be there e herebe heree backbe back 4.diebe dead5.leavebe away(from) 6.openbe open 7.closebe closed 8.go/get outbe out9.finish/end- be over 10.becomebe11.get upbe up 12.begin/start(上演)be on13. fall asleep- be asleep 14.fall ill be ill15. move here/there -be here/there 16. get to - be at/in 17.arrive at / in - be at / in 18.reach- be at/in 19.get married - be married 20.joinbe in/be a member ofjoin the Party- be in the Party / be a Party member/ be a member of the Party . 实义动词 型1.borrow- keep 2. buyhave 3.Begin to teachteach 4. get to knowknow5.Put onwear 6. receive-have7.catch a coldhave a cold 8.hear fromhave a letter from注意点 1上述例词除borrowbuycatch需转换为keep have外，其余均为“beadjadvn”结构。 2非延续性动词并非不可用于现在完成时态中，只是不能和表示“一段”时间的短语连用，但可与just，yet，already ，ever，never等连用。例如： They have already come He has just gone out 延续性动词与非延续性动词专项练习1.
