I (sit) at the computer and I (do) an English exercise. I often (work) with the computer. I (think) computers are great. When our parents (be) at school they (not - have) computers. They (must) write everything in their exercise-books. And there (be) no internet. They (go) to the library and (find) everything in books. Today you just (enter) one word into your computer and you (find) thousands of pages where you (can - read) about it. But even today some people still (like) books. Some people (not - like) computers. My grandma still (read) a lot. She (not - use) a computer.
