There are some differences between American English and British English. Some differences are quite interesting. When my friend Lily from London used the word "larder", I didn't know what it meant. Realizing I didn't follow her, she used another word. I finally knew she wanted to find something to keep some food. The next word came up when we were planning a lunch date. She _ the date and time in her diary, while I marked my calendar. If she called me on the phone, she would ring me up. But if the line was busy, she would say the line was engaged. Most times, I can know what Lily means. Last week, she regretted sending her boys to watch an early morning tennis game without their fleeces. I thought that she meant without their jackets or something like that. Other times, we have to ask each other. She recently told me a funny tale about a pissed woman. I wondered what had made the lady angry. It turns out that pissed means drunk. Here is one more example. My British friend Jane was filling out a ticket at the grocery store recently. She asked the young man to help her if he had a rubber. When she noticed he didn't follow her, she quickly asked for an eraser, which, in England, is often called a rubber. In order to communicate well with British people, we Americans should learn some words that the British use differently. And I think people who learn English as a second language should also realize that there are differences between American English and British English. What is the passage mainly about?
The British way of using words. Some new words the writer's British friends taught her. The reasons why Americans can't followed the British at times. Some words used differently in British English and American English.
