cutting ：用刀切東西
edge：東西的邊緣
Cutting edge：類似刀或斧頭這些工具的銳利邊緣，即刀口。現在已經被用來表示：最先進的技術。這個俗語在美國人當中流傳使用已經大約有四十年了，一般是用來形容科技發展領域最先進的研究和發明，因此這個習慣用語在科技界人士當中使用得最多。 現在已經不侷限在科技領域了，它已經被用於社會的各個方面，甚至美國的音樂界人士也使用這個俗語。


例句：His cutting-edge research focuses on the nature of religious and spiritual practices and experience.

Grope

\ˈgrōp\  v. 

: to search for something by reaching or touching usually with your fingers in an awkward way
: to move forward carefully by putting your hands in front of you so that you can feel anything that blocks you
: to touch (someone) in an unwanted and unexpected sexual way
觸摸,探索,探求,暗中摸,摸索

When you grope for something, you try to get a grip on it. If you drop your flashlight in a dark cave, you might grope around for it. Beware of snakes!

If you're asked a question and you grope for an answer, you're at a loss for words. You can also grope another person, although I wouldn't recommend it: grope is usually used to describe touching that is unwanted (i.e. creepy behavior). If you do grope someone, don't bother groping for an explanation when you get slapped or arrested.


例句：The ordinary people often grope around inside the box created by their own ignorance.
常人經常在他們自己愚見所畫的框框裡爬行。

Wondrous

\ˈwən-drəs\  adj. 

causing wonder or amazement ；very beautiful or impressive；wonderful; remarkable
令人驚奇的,非常的

The adjective wondrous is a great word to use when you're describing something amazing or delightful. You could talk about the wondrous view of the ocean from the cliffs where you're standing.

There's a hint of magic and awe about the word wondrous. It describes things that inspire wonder, like a wondrous imaginary land or a wondrous display of beautiful, elaborate cakes at a pastry shop. The root is the Old English wundor, "marvelous thing, or object of astonishment." Wondrous is tricky to spell because it's missing the e in wonder.

 Origin:
1490–1500;  metathetic variant of Middle English wonders  (genitive of wonder) wonderful; cognate with German Wunders;  spelling conformed to -ous 

例句：
He told us some wondrous experiences while practicing Falun Gong.
他告訴我們一些修煉法輪大法後的神奇經歷。
