Answer 1

第五题：
consider sb/sth + n.“认为某人/物是...”,
被动语态是：sb/sth be considered + n. “某人/物被认为是...”
如果用known, 是不合适的。因为know不能带宾补，即没有know sb/sth + n 这种用法，当然也没有被动时sb/sth be known + n. 的句型了。

第七题：
此句话的意思是“美国人吃奶酪比一些国家的人少。然而，每年每人还要吃八到十磅的奶酪。”
此题关键点是：yet they still ...
如果前面说美国人吃奶酪比一些国家多，就不能再说“然而他们还...”了。想想逻辑上的合理性。

Answer 2

第五题如果要用known的话,也行,但known后面要加上as.这是个固定搭配be known as..."被认为是,众所周知".
第七题选less是因为,那句话的yet.它有转折的意思,"尽管,然而",如果选A,逻辑就翻译不清了.
