用法：be glad to後面跟動詞原形，相當於be willing to。

例句1：The officials are glad to cooperate with her by showing her the products that are available.

官員們很高興與她合作，並向她展示可購買的產品。

結構分析：The officials是主語，are glad是系表型謂語（系動詞are +表語glad）， to cooperate with her是不賓式片語作賓語，by showing her the products that areavailable是狀語，其中that are available是定語從句。
