　　(1) Tudging to be the best boxer of his time， sugar Ray Robinson lost only 3 out of 137 fights (94.1)

　?。鄞鸢福?A 此分詞短語與其邏輯上的主語sugar Ray Robinson 是被動的關(guān)系(Sugar was judged to be…) 故應(yīng)用過去詞Tudped to be。

　　(2) During the Colonial days， the Iroquois had an agricultural economy basing mainly on corn with supplementary crops of pumpkins ，beans， and tobacco. (92.1)
