同学你好~
The Crystal palace which was built for the great exhibition was different from all the other buildings. For it was made of iron and glass.跟前面一样，可以改为The Crystal palace which was built for the great exhibition was different from all the other buildings， because it was made of iron and glass.
“attacked” 拼写错误哦~根据语境这里应该是 “attracted”（吸引），“attacked” 意思是 “攻击；袭击”，不符合句子想要表达的意思。
“from the all parts of the world” 表达有误，应改为 “from all parts of the world”，“all parts of the world” 表示 “世界各地”，不需要加定冠词 “the” 。
“by the steam boat to European” 存在错误。“European” 是形容词 “欧洲的” 或者名词 “欧洲人”，这里应该用 “Europe”（欧洲）；同时，“by + 交通工具” 表示出行方式时，交通工具前不用加 “the”，应改为 “by steam boat to Europe”。
“Then crystal palace was moved to South London” 中 “crystal palace” 应该大写为 “Crystal Palace”，因为这是特定的建筑名称，属于专有名词。
希望对同学有帮助~
