Exercise 1: Use the correct form of verbs in brackets.

17. We never (meet) __________ him. We don't know what he (look) __________ like.

18. The car (be) __________ ready for him by the time he (come) __________tomorrow.

`Answer:`

`17,` have never met `-` looks

`@` Vế đầu chia HTHT vì có "never"

`@` Công thức: $\text{S + have/has + Vpp}$

`@` Vế sau chia HTĐ: $\text{S + V(s/es)}$

`18,` will have been `-` comes

`@` By the time + HTĐ, TLHT: Nói về `1` hành động xảy ra và hoàn tất trước `1` hành động khác trong tương lai

`@` Công thức TLHT: $\text{S + will/shall + have + Vpp}$

`#TD`

`17`. We ( meet ) have never met him. We don’t know what he looks like.

`=>`-> have/has `+`never `+`V3/ed

18. The car (be) will have been ready for him by the time he (come)  comes tomorrow

`=>` TLHT `+` by the time `+` HTĐ

`@`Note :

Thì tương lai hoàn thành :

`+`S + will + have + V3/pp

`-`S + will not + have + V3/pp

`?`Will + S + have + V3/pp +…?

Thì hiện tại đơn :

`-`Tobe :

`+`S + am/is/are + N/Adj

`-`S + am/are/is + not +N/Adj

`?` Am/Are/Is (not) + S + N/Adj?

`-`V-thường

`+` S + V(-s/-es) + O

`-`S + do/does + not + V + O

`?`Do/Does (not) + S + V + O?
