North AmericaPPT，第二部分内容：句型透视

1To the south of Canada is the United States. 加拿大的南面是美国。

[探究]此句的主语是the United States, to the south of Canada作系动词is的表语，此句可转化为：The United States is to the south of Canada.其中to the south of 意为“在……的南方”，to要用在方位名词前面。

[拓展] in, on, to均可表示地理位置：in 指在某一范围内；on 指两者相接壤；to 指两者不接壤。例如：

D is to the north of A．D 在 A 以北。(不接壤)   

C is on the north of A．C 在 A 的北边。(接壤) 

B is in the north of A．B 在 A 的北部。(在内部)

2The Yangtze River (the Changjiang River) in China is the third-­longest river in the world. 中国的长江是世界第三长河。

[探究] ““the ＋________＋_________＋名词”表示“第几……的……”，如表示“第一……”，则可以省略序数词first。例如：

The Yangtze River is the longest river in China. 长江是中国第一长河。
