One day, when she was to 7 at a lunch party, a reporter caught her off her guard by bringing up the 8 of her missing son again．She was totally mental 9 for the question and lost her 10 ．Tears were rolling down her eyes 11 she sobbingly(啜泣)told the reporter that there was still no 12 of Mark and that she was very 13 about him．She said that all the countries concerned had promised to do their best to help her find her son．With that she 14 down completely and sobbed silently for quite a while．Gradually she 15 down and started to speak as planned．It was a very 16 scene which exposed a new side of Mrs．Thatcher's 17 the public do not usually see, so people began to 18 about the Iron Woman’s motherly love, a feeling that is common to all human race．
