`1` We don't have Math class today (Ko có tiết học Toán hôm nay = Ko học toán hôm nay)
`2` Why don't we listen some rap music now ? ( Let's + V + O = Why don't we + V ? : Hay là )
`3` Lan is very good at Maths ( be good at + N : giỏi về )
`4` English is not difficult to learn ( is easy = is not difficult : dễ = ko khó )
