这个探险队里有许多学有专长的专家。

There were many experts who had different expertise in the expedition.

我的答案大概会是这样：“要学有专长，最好是在高技术领域（譬如工程学）。

To this question, my answer would be something like this: "I'll develop a strong specialization, preferably in something highly technical (eg engineering)."

那些学有专长的学者，自己虽未能找到人生的答案，却又对谦卑信徒的信心嗤之以鼻。

The professedly learned are forever trying to bring to nothing the faith of the humble believer, but they fail in their attempts.
