For the first time in a long time, the recovery looks as if it might be starting to sputter a little bit.

Everywhere you look, after all, there has been less-than-stellar news recently. Consider the fact that the economy not only added a 75,000 jobs in May — 180,000 had been expected — but also that, after the latest revisions, it turns out it added 75,000 fewer jobs than we had thought in March and April. 

根据上文文的语境，这里的added应该是加起来是的意思吧。是一个不及物动词，做谓语。翻译it turns out it added 75,000 fewer jobs than we had thought in March and April. 五月份增加的工作岗位（75000个）比我们在三四月份预期增加的工作岗位 少了75000个。
