According to some analysts, the gains in the stock market reflect growing confidence that the economy will avoid the recession that many had feared earlier in the year and instead come in for a "soft landing", followed by a gradual increase in business activity. 此处为什么用过去完成时many had feared earlier in the year?不是说过去完成时时为了表示过去的过去吗?必须有过去时与之对比才行? 烦请大家给解释一下。多谢!
