当描述一个人长得很高很瘦时，英文中可以使用 'tall and lean' 或者 'long and slim' 这样的短语来描写。下面是一篇关于一个长得很高很瘦的人物的英文文章：

John was a tall and lean young man. His height was remarkable, towering over most people he encountered. He had a lean and athletic build, with long arms and legs that seemed to go on forever. His angular face and chiseled features gave him a striking appearance, and his piercing blue eyes added to his allure.

Despite his height, John moved with a certain grace and ease, as if he had been born to it. He was often mistaken for a basketball player or a model, but in reality, he was simply blessed with good genes and a natural athleticism.

In his spare time, John enjoyed playing basketball and running. He had a competitive streak in him and loved pushing himself to his limits. His height gave him an advantage on the basketball court, but it was his speed and agility that really set him apart from his opponents.

Despite his physical prowess, John was also a gifted writer. He had a way with words that was both poetic and insightful. His writing was often introspective, exploring the depths of the human experience with a keen eye and a sensitive heart.

In many ways, John was a paradox. He was both physically imposing and emotionally sensitive, a combination that made him all the more intriguing. His height and lean frame made him stand out in a crowd, but it was his talent and intellect that truly set him apart.
