我学了一个新的词语：婆婆（ is equal to 岳母 yuemu) 我和我的婆婆聊了聊。 I talked to my mother in law. 上周，我给她打了电话，I called her on the telephone. 她告诉我 She told me that, 她下山的时候摔倒了。she had been walking down the mountain and fell down. 她把手臂摔伤了（ is equal to 她摔伤了手臂）She broke her arm. （她把手臂摔断了 is correct in grammar,but doesn't conform to the actual. When you arm brake into two parts, how can you walk alone?) 不过， However， 在那时她身旁没有任何人。There was no one. ( 她身旁没有人来帮助她 I think this sentence has two meanings: 1.There are people ,but the people don't help her. 2. There is no noe.） 所以她只能自己走回家。 so she had to walk home by herself. (You use 散步 there is not suitable, 散步 is usually refer to a relaxing walk. EX 吃完晚饭，他在院子里散步。 After having supper, he went for a walk. *现在她手臂上的伤已经痊愈。（她的手臂已经好了is more common) Now her arm is healing well. *我很开心她的手臂已经好。 I am very happy she is okay. *This two sentences can write in a easier way 现在她的手臂已经好了，对此我感到很开心（is equal to 高兴）。
