English words don't stay the same. People need new words for new ideas and new inventions. Different words come into use, or older words are used in a new way.

English can change by borrowing words from other languages. For example, the word "tomato" was borrowed from Mexico and "tea" came from China. New words are formed by putting two words together sometimes. "Countryside" and "earthquake" are made up of two parts. Sometimes new words are shorter forms of older words. As we know, the word "photo" was made from "photograph" by cutting off the end of the longer word. "Plane" was made by cutting off the front part of "airplane". The names of people and products(产品) can become new words, too. Our "sandwich" was named after a man called Sandwich and "sellotape"(透明胶带) was a name given by the company that first made the product.

1.New English words are needed because _______.

A. people use old words in a new way　　 B. people need a new way to explain things
