「shock」の使い方

I was explaining an English mistake to someone, and her jaw dropped:

"ショックです!"
"How do you say that in English?"
× I am shock!
○ I am shocked!
jaw drops 《someone's ～》びっくりする (definition from Eijiro on the Web)

"Shocked" is an adjective, but "shock" is a noun.

• It was a shock to hear the news!
• It is no shock that the US is having economic trouble now. <- it isn't surprising

Nowadays, many people seem afraid of the flu. Not me, though. The symptoms seem relatively mild, and besides, diseases like TB (tuberculosis) seem much scarier.

• 結核 (けっかく) (n) tuberculosis; tubercule; (P);

Don't be shocked when reading this article, either. It says that masks won't really protect you from the flu.

Wash you hands, stay healthy, and use "shock" and "shocked" correctly!
