A surge in new home sales and a drop in weekly unemployment claims suggest that the economy might not be as weak as some analysts previously thought.
C. claims suggest that the economy might not be as weak as have been previously thought by some analysts.

这道题目A是正确的，但是LZ不是很理解OG对C的解释：the sentence offers no plural subject to fit the passive verb have been thought. 但是LZ怎么觉得这里have been thought的主语就是analysts?
请解答！

第一种方法：语义分析，A,经济没有分析家想的那么弱；C,经济没有被想到像那么弱通过专家。c读的别扭
第二种方法：主动优于被动

OG的解释虽然只是一方面，但却没有错，the economy 确实不能用have been thought这种复数形式表达。

你认为have been thought的主语是scientist，那就还原到句中看看对不对，'scientists have been thought by scientists'，从句的主语已经明确列出来是economic，为单数，不能用复数的have。

顺便再想提一下时态问题，请翻到og13 p669，参阅一下present perfect：过去某不确定时间发生的或在过去发生一直延续到现在的。现在科学家已经改变了原先的想法，那现在完成时是不合适的。过去时可以表示过去经常性、习惯性的行为，在这题里较合适。

愚见，希望对你有帮助哦~
