   For a long time,scientists didn’t study animal thinking.

   Most of them didn't believe that animals could think. They thought humans were the only thinking animals.

   Now more scientists are studying this subject But is’s very hard to prove things that no one can see or measure. So some scientists decided to take a look at brains.

   Is bigger better? No cow brains are bigger than dog brains,but that doesn’t make cows smarter than dogs. And squirrels (松鼠) have some of the biggest brains of all for their body size. But squirrels aren’t even close to being the smartest animals in the world So the size of a brain may give some clues about brain power,but it doesn’t prove anything.

   Other scientists study thinking by watching how animals solve problems,who watch animals in the wild or set up thinking tests in a lab. For example,a scientist might put some food just out of an animals’s reach. One kind of animal may grab (奪取) a stick and use it to slide the food over. Another kind might not be able to figure out a way to get the food. Some scientists think animals that have lots of Problems to solve must be smarter than animals with simple lives. Scientists also study certain kinds of behaviour for clues (線索) about thinking. They watch for three things： whether animals use tools,how they act with each other,and how they communicate

1. For the body size,do dogs have smaller brains than squirrels?

2. What have scientists learnt from taking a look at the size of animals 5 brains?

3. How do other scientists study animal thinking?

4. What are some certain kinds of behaviour for clues about thinking that scientists study?

            There are different outdoor activities for different seasons. In spring we can fly kites. In summer,we can go swimming or sailing. In autumn,it is a good idea to camp or hike. In winter,we can go to ski or skate. They bring us a lot of fun. They make us strong and fit,too. So it is important for people of all ages to take part in some outdoor activities at the right time.

            There are many group activities,like football and basketball. The members work together for the same goal (目標(biāo)). So group activities need team spirit (團(tuán)隊(duì)精神). It is very useful for a person to have team spirit. It is good for us in life and work.

            Old people like walking and jogging. These outdoor activities don't need much strength (氣力). Young people like exciting activities like diving (潛水)， skiing and horse riding. Children like fun activities like flying kites,some outdoor activities are dangerous,like climbing rocks. So we must be careful when we take part in them.
