— Have you seen Michael recently ?— Yes, in fact I saw him this morning. I ____ him for two years. 

Mrs Turner told me that she ______ to many cities across China when she was young. 

 My uncle from Hongkong has changed so much that I could hardly ________ him at the airport. 

—Hurry up！Alice and Sue are waiting for you at the school gate.—Oh！I thought they ________ without me.
