Level Passage : 2:30 Lesson 5 Jet Reading 22 ⑤ Questions: 2:00 Compared to dogs and other pet animals, cats often have lots of freedom. Many owners let their pet cats go outside whenever they want to. But where do they go? Does your cat visit your neighbor's house for extra food? How far from home does your cat actually travel? Cat owners have been wondering about such questions for a long time. 5 To find out where cats go and what they do, researchers decided to track them by putting a GPS (Global Positioning System) device around their neck. It is well known that cats are natural hunters. They often chase and catch *wildlife, such as birds and other small animals. It was therefore believed Hoor war301 that cats may go far from their homes to hunt. However, the research showed some surprising facts about cat *behavior. It seems that most cats 10 don't travel very far from their homes. On average, they move around two houses away. Owners were *relieved to hear this result because it confirmed that their cats do not cross major roads. There was another interesting result. One female cat walked more than 1 kilometer from her home. When the owner checked her GPS data, they discovered that the cat had gone to their old house. It showed that cats remember the past longer and more clearly than we think.(219 words) *wildlife 44 *relieve ~を安心させる *behavior Infogt) A Choose the best options.

Introduction to a magazine article How much sleep is enough? Lots of studies have found that the less you sleep, the worse your performance will be. Many studies show that, generally, if you do not sleep enough, you will do worse in exams. So, does more sleep mean better exam results? That would be too simple. For example, you still have to study well in the first place. But research shows that people who sleep well can also study better. In this article, we are going to look at the research inmore detail. We will explain what it means to “study better” and say how much sleep you need.
