Not this

Use this

动词 share 表示“给某人看/分享”时，搭配介词是 with，而不是 to；可以说 share sth with sb，对应中文“和某人分享”，不能说 share sth to sb。
Not this
My sister and I share bedroom.
Use this
My sister and I share a bedroom.
share 后接可数名词单数表示“共用”时，需要冠词，如 a bedroom；这里不是指“卧室”这个概念，而是指一间具体的卧室，所以不能省略 a。
Not this
She shared me the good news.
Use this
She shared the good news with me.
share 不接双宾语，不能说 share sb sth；正确结构是 share sth with sb。中文“告诉我好消息”容易让人误用双宾语，但英语里 share 需要介词 with。
