23、,1. 肯定句：主语+was / were+及物动词的过去分词+其他.,e.g. Paper was invented by Chinese people two thousand years ago. 纸是中国人在二千多年前发明的。,2. 否定句：主语+ was/were not+及物动词的过去分词+其他.,e.g. Women were not allowed to take part in the games at first. 开始妇女不允许参加奥运会。,e.g. Was this picture drawn by your sister? 这幅画是你妹妹画的吗？,3. 一般疑问句：W
