` 1 ` : ` D ` I think watching television is interesting.

` - ` Ta có cấu trúc find `= ` think như sau :

` - `S+ find + V-ing / N + adj

` = ` S + think + V-ing / N + is + adj

` - ` Ta lại có cấu trúc thì hiện tại đơn

` ( + ) ` : S + Vs/es

` - ` Vì chủ ngữ là I + V nguyên mẫu ` => ` Động từ think giữ nguyên , không chia

` 2 ` : `A `

` - ` The last time + S + V-ed / V2 + 1 khoảng thời gian + ago

` =` S + haven't / hasn't + ` V3 `+ for + 1 khoảng thời gian

` - ` 10 years là 1 khoảng thời gian nên dùng for chứ ko dùng since
