參考譯文：

　　It has been a common problem in large city residents' life that it's hard to take a taxi. The increase of urban population and diversification of social activities make the demand for taxi rise. As the traffic jam becomes worse in cities，to guarantee personal income, many taxi drivers refuse to drive on busy roads and main urban areas, which makes it difficult for many citizens to take a taxi near some transportation junctions, commercial centers and hospitals. City construction affects the efficiency of taxi. Being not standard in the taxi industry and taxi drivers' often refusing to take passengers are the human factors that make it difficult to take a taxi.

　　詞句點撥

　　1.打車難:可譯為it's hard to take a taxi,作為problem的同位語，意義表達清楚自然。

　　2.增加了對出租車的需求:可譯為make the demand for taxi rise。

　　3.為避免堵車影響收入:可靈活地譯為to guarantee personal income。采用逆向譯法，上下文反復出現(xiàn)“堵車”這個詞，所以可以省略。

　　4.出租車行業(yè)不規(guī)范，拒載行為屢屢發(fā)生:這里是說明原因，為了句式簡明，可以處理為動名詞和獨立主格的形式，直接充當句子主語。

　　5.人為因素:可譯為human factor。
