1 This doctor, whom you visited yesterday, is famous
2 Her brothers, both of whom are policeman, are good people
3 That is the man whose car was broken yesterday
4 My school has a big playground, where the students often do PE
5 He didn't tell me the reason why he didn't appear in the class yesterday
6 I love Ha Noi, where I was born
7 He always respects his mother, who used to be a politician
8 Opposite my house is a park, which has a lot of beautiful flowers
9 He admires "The Great Gatsby" , which he has read for several times
10 They like shopping in that shopping mall, whose seafood is very fresh
11 We want to come back to that time, when we had good memories
12 Amy, who has just moved to England, is one of my oldest friends
13 Paris, which everyone wants to visit once in a lifetime, is a beautiful and romantic capital
14 They live in a luxury villa which was built 10 years ago
15 Alex, who works for Vin Group, is my best friend
16 Do you remember that day, when we first met
17 I miss Ha Noi, where I was born
18 Venice, which attracts thousand visitors per year, is a touristic city
19 Amy, whose parents are very strict, wants to live independently
20 This house, where we used to live, is her present for me
