Never make these mistakes in Chinese 02

Foreigners often make some strange mistakes in Chinese when they study the most difficult language--- ---Chinese. We try to analyze typical sentences to correct these errors.

          Wǒ jīnnián 21 nián.
False：我今年21年。
          Wǒ jīnnián 21 suì.
True：我今年21岁。

英语year可以表示时间（in the year 1985），也可以表示年龄（He is 20 years old）。汉语的“年”则只表示时间，应将受英语影响的“年”改成汉语表示年龄的“岁”。

"Year" in English indicates time(in the year 1985)as well as age(He is twenty years old). But 年 in Chinese only refers to time. 年, the use of which here is the consequence of interference of English language, should be changed into 岁 meaning age.
