In a 2001 study of 158 hospital nurses，those who faced considerable workdemands bud coped with the challenge were more likely to say they were in goodhealth than those who felt they couldn't get the job done.
本句的主干是those...were more likely to say...than those...其中，who引导的定语从句who facedconsiderable work demands but coped with the challenge修饰第一个 those, who felt theycouldn't gel the job done则修饰第二个those ; they were in good health为say的宾语从句;theycouldn't get the job done为felt的宾语从句。
get sth. done意为“做完某事”，通常是由自己完成。如:I want to get my car repaired.我想自己把车修理修理。have sth. done意为“让某人做某事”，通常由别人来完成。如:I want to have my hair cut.我想去理发。(让别人给剪头发)

We need a considerable sum of money.我们需要一大笔钱。
