    American President Roosevelt's house was once broken into and lots of things were stolen. Hearing this, one of Roosevelt's friends wrote to him and 1 him not to take it to his heart so much. President Roosevelt 2 back at once, saying, “Dear friend, thank you for your letter to comfort me. I'm all right now. I think I should thank God. This is because of the following three 3: firstly, the thief (小偷) only stole things from me 4 did not hurt me at all; secondly, the thief has stolen some of my things 5 all my things; thirdly, most 6 for me, it was the man 7 me who became a thief.”
