182. Average income for a household of people of working age, by contrast, has fallen five years in a row.
译文
相反,工薪阶层家庭的平均收入已经连续五年下降了。点睛
本句是个简单句,主干是...income...has fallen...。for引导的介词短语for a household of people of working age作定语修饰income,by contrast为插入语。by contrast意为“相反;相比之下”。如:
Lucy seems prettier by contrast with her sister. 露西与她妹妹相比似乎更美些。
in a row意为“连续;成一排”。如:
This is the fifth day in a row that it's snowed. 这是接连第五天下雪了。
考点归纳
与by contrast意思相近的短语还有:
By contrast with his peer, Tom is much more intelligent. 和同龄人比起来,汤姆要聪明得多。

Beijing is larger by comparison. 相比之下,北京比较大。

On the contrary, the housing price keeps going up after the reform. 正好相反,改革后,房价持续上涨。
