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.
1.打车难:可译为it's hard to take a taxi,作为problem的同位语，意义表达清楚自然。
2.增加了对出租车的需求:可译为make the demand for taxi rise。
3.为避免堵车影响收入:可灵活地译为to guarantee personal income。采用逆向译法，上下文反复出现“堵车”这个词，所以可以省略。
《诗经》 The Book of Songs
Long before the emergence of the written word, ballads and myths, passed around by word of mouth, were widely popular. Chinese literature finds its origins in these traditions. However, ballads were what people improvised out of daily life, and due to lack of means to record and preserve them in ancient times, they quickly disappeared without leaving much of a trace. Today, we can only deduce their existence from ancient books, which recorded some time-honored ballads, though most of these are believed to be derivatives of later generations. Ballads in The Book of Songs are the earliest writings that can be dated. From this point of view, ancient mythology has had a greater influence on Chinese literature.
