Question

Составить 6 специальных вопросы A) There are five stages of sleep: stages 1, 2, 3, 4 and REM. In stages 1 to 4 our body becomes more relaxed. Our muscles and heart rate slow down and our brain becomes less active. Stage 5 is called REM sleep. Our heart beats faster and our eyes move quickly in different directions. We dream during this stage and we can’t move at all-probably to stop us from doing the actions in our dreams.B)An average person spends almost a third of their life sleeping! Is it a waste of time? Scientists believe that when the heart and brain slow down, the body is recovering after the day’s work. They also think that REM sleep is important for memory and learning-babies have twice as much REM sleep as adultsC)On average an adult needs about 7-8 hours’ sleep every day. A baby needs 12-16. In the animal world, bats sleep for about 20 hours every day. But a giraffe sleeps for only 30 minutes or an hour per day.​
