1. It's a pity that you can't stay longer => I wish ___________________________________ 2. This mobile phone is not as cheap as i thought it would be => This mobile phone is __________________________________

`1.` I wish you could stay longer.

Cấu trúc wish (ước ai đó được làm gì): S+wish(es)+S2+V (lùi thì)+...

Lùi thì động từ: can `->` could

`2.` This mobile phone is more expensive than I thought it would be.

Không rẻ như tôi nghĩ `->` đắt hơn tôi nghĩ `->` dùng câu so sánh hơn

Cấu trúc: S+tobe+adj_er/more adj+than+S2

* expensive là tính từ dài nên dùng more adj
