Giải thích các bước giải:

$+)$ Cấu trúc chuyển từ dạng so sánh hơn sang so sánh ngang bằng ở dạng phủ định:

So sánh hơn: `S_1` + be/V + adj-er/more + adj + than `S_2`.

`->` So sánh ngang bằng ở dạng phủ định: `S_1`(được chuyển từ `S_2`)+ be/V + as + adj + as + `S_2` (được chuyển từ `S_1`).

$+)$ Cấu trúc chuyển từ dạng so sánh ngang bằng dùng đại từ bất định sang dạng so sánh hơn nhất:

So sánh ngang bằng sử dụng đại từ bất định: ĐTBĐ (O) + is + as + adj + as + S.

`->` So sánh hơn nhất: S + be + the + short adj/most long adj (O).

*short adj: tính từ ngắn.

*long adj: tính từ dài.

*ĐTBĐ: Đại từ bất định.
