(√)Tom has been here for two hours. 汤姆刚到。Tom has just come. Grammar 2 (1) 转化为“be+形容词/副词等”; die → be dead leave → be away (from) open/close → be open/closed stop → be over arrive in (at)/reach/get to → be in/at join → be a member of/be in start/begin → be on (2) 转化为意思相同的延续性动词。 borrow → keep buy → have become/come →be get to know →know 终止性动词可以和延续性动词进行转换。 —How long have you had your bike —I’ve had it for about two years. How long have you studied at this school How long have you studied English How long have you known your best friend 4.How long have you lived in this place 5.How long have you used this book 瞬间动词与for 或since引导的时间段连用时要变成延续性动词。 Speaking 1.
