1.、1,025 meters deep 1025 米深
【用法詳解】“基數(shù)詞+ meter(s) deep”是一種“深度”的表達法。其中meter為表示度量的單位名詞，意為“米；公尺”，類似的單位詞還有ft（英尺）、inch（英寸）、kilgram（千克）等。
Eg.The hle is abut 6 meters deep. 這個洞大約6米深。
【歸納總結】英語中長、寬、高等的表達方式：
2、 Qmlangma is higher than any ther muntain in the wrld. 珠穆朗瑪峰比世界上其他任何山都高。
【用法詳解】any ther意為“其他任何一個”，其后跟可數(shù)名詞單數(shù)，常用于比較級句型，表達最高級含義，相當于“any f the ther +名詞復數(shù)”
The Yangtze River is lnger than any ther river in China. 長江比中國的其他任何一條河流都長。 = The Yangtze River is lnger than any f the ther rivers in China. = The Yangtze River is the lngest river in China. （長江是中國最長的河流）
【拓展延伸】“比較級+ than + any ther +單數(shù)可數(shù)名詞”結構通常用于在同一范圍內進行比較。如果相互比較的人或物不在同一范圍或不屬于同一類別，則用“比較級+ than + any +單數(shù)可數(shù)名詞”結構。
Eg.Tm runs faster than any ther student in his class. 湯姆比他班里的其他任何學生跑得都快。 Shanghai is larger than any city in India. 上海比印度的任何城市都大。
