`1`.He hasn't gone abroad before

`\rightarrow` S + haven't / hasn't + VpII + before : Chưa làm gì trước đây

`2`.She has driven for 1 month

`\rightarrow` Thì HTHT : S + have / has + VpII ( `2 , 3` )

`\rightarrow` For + Khoảng thời gian ( `2 , 5 , 6` )

`3`.We have eaten since it started to rain

`\rightarrow` Since + Mốc thời gian ( `3 , 4` )

`4`.I haven't had my hair cut since I left her

`\rightarrow` Thì HTHT ( PĐ ) : S + haven't / hasn't + VpII ( `4 - 6` )

`5`.She hasn't kissed me for 5 months

`6`.We haven't met for a long time

`7`.How long have you had it ?

`\rightarrow` Thì HTHT ( NV ) : Have / Has + S + VpII ?

`\rightarrow` How long dùng để hỏi về bao lâu [ Tương đương với " For " ]

`=>` Dùng thì HTHT

`8`.I haven't had such a delicious meal before

`\rightarrow` S + haven't / hasn't + VpII + such + a / an + adj + N + before 

`=>` Chưa làm gì trước đây

`9`.The last time I saw him was 8 days ago

`\rightarrow` The last time + S + Ved / V2 + was + time / timeline : Lần cuối làm gì

`10`.It is Monday since I last took a bath

`\rightarrow` It is + time / timeline + since + S + last + Ved / V2 : Đã bao lâu kể từ khi ... lần cuối làm gì
