1.I saw the boy and his dog that were crossing the street.
2.That is my sister whom you saw yesterday.
3.The food, of which the flavor meets many tastes, is delicious.
4.I don’t know the reason why you didn’t go to school.
The green book which is lying on that table is yours
That is the reason why she always misses me
The tall boy whom you see at the door is my brother
I have two sisters, both of whom are students. She tried on three dresses, none of which fitted her.
These books are all that my sister left me.
