`1` You must wear trainers in the sports centre at all times.

`->` Chủ động: S (O) + must + V. 

`2` Last month, Mary's friend said: "Why don't we join a dance class?".

`-` suggest doing sth: đề nghị, gợi ý làm gì

`=` Why don't we + V?: tại sao chúng ta lại không ... nhỉ? `->` câu đề nghị

`3` It took us five and a half hours to fly to Paris.

`-` last (v): kéo dài

`-` It + take (chia theo thì) + sb + time + to V: ai mất bao lâu để làm gì

`-` flight (n): chuyến bay `->` fly (v)

`4` In spite of having a bad cold, she still went to work.

`-` Hai mệnh đề đồng chủ ngữ "she" `->` dùng V-ing `=>` having

`5` It's years since the last time I enjoyed myself so much.

`-` S + has/have + not + PII + for + khoảng thời gian: ai chưa từng làm gì trong bao lâu
