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 yǒu bǎi duō kuài qián.
False: 我有百多块钱。
           Wǒ yǒu yì bǎi duō kuài qián.
True: 我有一百多块钱。

用在动词后的数词一可以省去,单说量词(如,我买本书)。此句动词有后紧跟着的是由百和多构成的表示钱数的概数词组。一要说出来。
The numeral 一 after a verb is understood. One may only read out the measure word(such as 我买本书). In this sentence, the verb 有 is followed by a phrase with 百 and 多 to indicate an approximate sum of money. Thus 一 must be read out.
