1.I have seen a great deal of him, have studied his sentiments and heard his opinion on subjects of literature and taste; and, upon the whole, I venture to pronounce that his mind is well-informed, enjoyment of books exceedingly great, his imagination lively, his observation just and correct, and his taste delicate and pure. His abilities in every respect improve as much upon acquaintance as his manners and person.

【難句解析】upon the whole 的意思是“總體上來說”；venture to do sth.意思是“敢于...”；“enjoyment of books exceedingly great,his observation just and correct, and his taste delicate and pure.”的enjoyment前省略了his，great，observation和taste后都省略了is；

【句子翻譯】我常常見到他，研究了他的情感，聽取了他在文學與鑒賞方面的見解。整個來說，我敢斷言，他知識淵博，酷愛讀書，想象力豐富，觀察問題公允而準確，情趣風雅而純潔。他各方面的能力和他的人品舉止一樣，你越是了解，印象越好。
