Rulers are everywhere. When you’re reading at the library, playing basket on the playground or driving on the road, you’ll have to follow some rules. But have you ever read any rules on a plane? If you’re traveling by air in America, you may find the following criteria (标准).
Exit Seat Criteria If you are sitting in an exit seat, read the information below. You must: ¶ Be at least 15 years old and healthy enough to offer help. ¶ Be able to speak, read and understand English well. ¶ Be able to follow a safe way from the emergency exit (紧急出口). ¶ Be able to help others away from the plane. You must not: ¶ Travel with a pet, such as a dog. ¶ Travel with someone that needs special care, such as a child. If you cannot meet the criteria, ask crew members (工作人员) to move you to another seat. You do not have to explain why, just say, “I do not want to sit in an exit seat.”
