例子八：蜘蛛俠的蜘蛛絲
超人懂飛，蜘蛛俠不懂飛。
但是蜘蛛俠可以用他的蜘蛛絲解決任何問題：
他用蜘蛛絲吊起自已，做成飛的效果。
蜘蛛俠的專長是蜘蛛絲，哪蝙蝠俠呢?

只有蝙蝠俠是有錢人，他可以用錢解決任何問題：
他購買昂貴的飛行工具。
（你的蜘蛛絲是什麼？）

So I would not find an English physics book boring. Also, the English in a Physics book would be easy. Reading English Physics book is a way to get used to reading English.
When I had found that, with the power of English, I was able to learn a lot of advanced physics, I started to like English. It is as interesting as my Physics, because English is part of my Physics.
