frighten vt. 使惊吓，惊恐
These words seemed to calm everyone, so they went back to bed. But I knew that I had heard two people fighting. I dressed and waited in my room, in case Mr. Rochester needed me. Soon Thornfield Hall was quiet again. Then I heard someone outside my door. "Are you awake, Jane?" said Mr. Rochester. "Yes, sir, and dressed." "Good. I need your help. Bring a clean cloth with you." Quickly and quietly we went up to the top floor. Mr. Rochester opened one of the small black doors. "Does the sight of blood frighten you?" he asked. "I don't think so," I said.We walked into a large, dark room with curtains hung on the walls. On one of the walls a curtain was pushed back. I saw a secret door that led into another room. From inside the room, I heard angry sounding noises. They sounded like an animal's but also like a human's.
