相反，工薪階層家庭的平均收入已經(jīng)連續(xù)五年下降了。
點(diǎn)睛
本句是個(gè)簡(jiǎn)單句，主干是...income...has fallen...。for引導(dǎo)的介詞短語(yǔ)for a household of people of working age作定語(yǔ)修飾income，by contrast為插入語(yǔ)。
by contrast意為“相反；相比之下”。如：
Lucy seems prettier by contrast with her sister. 露西與她妹妹相比似乎更美些。
in a row意為“連續(xù)；成一排”。如：
This is the fifth day in a row that it's snowed. 這是接連第五天下雪了。
考點(diǎn)歸納

by comparison意為“相比之下”。如：
Beijing is larger by comparison. 相比之下，北京比較大。
on the contrary意為“正相反，恰恰相反”。如：
