St. Lawrence
The Great Lakes are the greatest wonder of America. It is the largest group of lakes in the world and the biggest body of fresh water. It is hard to grasp that a land should contain several freshwater seas so big that a ship can steam out of sight of the shore for a day or more or even founder in giant waves, as happens from time to time. Let us approach the lakes the best way. We should get on board a ship and start from the Lake Ontario. It is the smallest of the Great Lakes, but compared with the other lakes, Ontario is more illusive. This Niagara Falls with its sheer thunderous drop has been an illusive barrier between this and other lakes, and the St. Lawrence sluicing out its eastern end draws Ontario's attention seaward. The Welland Canal, 27 miles long, with eight locks to lift the ship over the Niagara Falls Escarpment to Lake Erie, has beautiful scenery on both sides.
五大湖是美洲最壯觀的景觀，是世界上最大的湖群和最大的淡水儲存區(qū)。很難想象，一片陸地上的幾個淡水湖泊可以大到可以讓一艘船出航一天而不靠岸，甚至有時經(jīng)常翻起巨浪。　　 讓我們以最佳的方式來了解五大湖。我們可以從安大略湖上船。安大略湖是五大湖中最小的，但是比起其它湖泊，它又是最迷幻的。尼亞加拉大瀑布帶著它清澈的水花轟鳴而下，并成為安大略湖與別的湖泊難以分辨的界嶺。圣勞倫斯河位于安大略湖東側(cè)，湖水在此注入海洋。韋蘭運河長27英里，有8個船閘可以將船從尼亞加拉瀑布懸崖提升至伊利湖，在其兩側(cè)均有怡人的風景。
