答案與解析：
ensure his attendance at the meeting
本題句子的主幹 I called him up in advance 已經給出，無需翻譯，需要翻譯部分為 為了確保他能參加會議 。該部分在句子中作目的狀語。本題考查是目的狀語。①目的狀語可以由to/in order to來引導。②確保 ensure sb to do 確保某人做某事，ensure sth 確保某事為了確保他參加會議，我已經提前給他電話了。
said to have been built
本題句子的.主語為the significant museum，缺謂語，即(據說建成於)。about a hundred years ago為時間狀語。本題重點考查：①被動語態。主語museum與動詞build之間為被動關係; 且bulid這一動作發生在過去。②據說 be said to;be said to+ 動詞不定式的完成時，表示不定式表示的動作已經完成。據說這座意義深遠的博物館大約建成於一百年前。
