person.我一生中很少遇到意志这么坚强的人。[造句]　随即传来了一个小女孩的哭声。And then came the cry of a little

多被认为是表语。[即学即练]①Under that tree sits(sit) a beautiful girl.②Present at the conference were(be) experts from all over the world.③Such are the facts，no one can deny them.　have＋sb./sth.＋doing(教材P36) He had teams of dogs pulling the sledges and all his men were on skis.他让成群的狗拉着雪橇，所有人都在滑雪板上。句式分析：句中have teams of dogs pulling是“have＋sb./sth.＋doing”结构。[知识拓展]have sb./sth.doing现在分词表示进行和持续，宾语是动作的执行者。have sb./sth.do动词原形表示动作未完成，宾语是动作的执行者。have sb./sth.done过去分词表示已经完成，宾语是动作的承受者。[即学即练]①My mum has me reading(read) the poem all the morning.②We had the machine repaired(repair)．　 have difficulty in doing sth.(教材P37) The next to go was Captain Oates，who was having great difficulty walking.接下来离开的是奥茨船长，他行走非常困难。句式分析：句中have difficulty in doing sth.表示“做某事有困难”。[知识拓展]have some/much/great/little/no
