Where did you buy this lovely blouse? (в вопросе did, значит bought уже не может быть)
My friend and I often go for a walk together.(to go for a walk - устойчивое выражение)
What color is your mother's hair?(hair - в английском единственное число, поэтому is)
Don't eat too much ice cream.( ice cream - в англ неисчислимое)
Will your sister come to our party tomorrow?(будущее will come)
