四级词汇讲解:
本句为并列句，主干为this is a merry-go-round, and none of the institutions believe。前一个分句中that's going very fast是merry-go-round的定语从句。第二个分句中they can sustain the risks of trying to break away by themselves是believe的宾语从句。
merry-go-round在句中意为“一连串繁忙活动，走马灯似的更迭”，其本意为“旋转木马”。
break away的意思是“脱离，逃脱”，其后通常跟介词from。如:
They broke away from the national union to form their own union.他们脱离了全国工会，组建了自己的工会。
by oneself的意思是“单独，独自”。如:
The baby can now walk by himself.这个小宝宝现在可以自己走路了。
