这句话有问题不?帮俺找一下A mother and her young sons got into a bus and sat down.

got into a bus 这里不对了哦.
一般的,get on the bus ；get into the car.你想象一下那个动作,上公共汽车不需要弯腰,是登着台阶上的,而进轿车是弓着身子进里面去的.
其他的都对.A mother and her young sons got into a bus and sat down.The bus counductor came to their for her tickets.The mother said,"I wantone ticket to London."and give her two pounds.这一段有两个错误，请找出来！谢谢！and give her two pounds.这里错了哦and 连接两个动词，前一个是said ，是过去时，后一个是give 也应该是过去时，改成gave。
