2 . Billions of insects are moving together over the sky like a black cloud. It’s a swarm of locusts. Many insects move in huge swarms. They form swarms for different reasons. Some move together to look for food or to find new homes. Sometimes insects swarm for protection. These enormous swarms can destroy food crops and harm other living things.

When something disturbs a red fire ants’ nest, out they will come. Not just one or two, but thousands of them. The fire ants swarm all over their victim. Their stings burn like fire. Each ant in the swarm can sting over and over again. The fire ants hold onto their victim with their mouth parts. Then they inject their prey with poison. Most small animals cannot survive the stings from a swarm of fire ants.

When army ants are on the move, anything in their path is prey. Even snakes can’t escape a swarm of these stinging ants. Army ants move together to look for food. They can’t see their prey, but they use smells and sounds to find their way. If they come to a river, they make a bridge with their bodies. They cling together with their legs. Then the rest of the ants can cross the bridge. There is not much that can stop these fierce and cruel ants from chasing their prey.

Insects are not the only animals that swarm. There are many others that do. Most are not harmful to people. Being close to a huge swarm of animals can be scary and dangerous. Some scientists have studied animal swarms. They have found that many swarms follow simple rules. They work together to solve problems. When they work together they are a very strong team.

4 . It was 6 a.m. as I got on the train, ending my work one cold morning and I was lucky to get a seat. At that time of the morning, my eyes were not fully focused and at times I was half asleep. During that time the train was usually filled with construction workers heading out to start their work. On that particular morning I found myself drawn on the shoes of men sitting about 10 seats across from me.

I sat examining the shoes of men. Men from different walks of life, holding different jobs, thinking different thoughts, living different lives and despite what they did and how they looked, they all had something in common. They were all of the working class trying to achieve their dreams.

One day each of those men has to visit a shoe store to buy a new pair of shoes, a type that fits their working needs. For a short time those shoes look so good. Then one day they lose their shine; they no longer look as good, but guess what? The shoes feel right. Feet have found their own home within the comfort of those shoes.

If those shoes could talk, what kind of a tale do you think they would tell? If your shoes could talk, what do you think they would say about you? Would the story be about a journey filled with joy and fun? Or would the story be one filled with disappointment and regret?

We choose the shoes. Where we take them and when and how we wear them are up to us.

7 . Many factors in our life can lead to anxiety and stress. Luckily, there are several simple ways of relieving stress. Most of these steps are responsible for the improvement of your overall health as well.     1     Physical activity leads to a lowering of the overall stress levels and it also improves your quality of life both physically and mentally.

Any physical activity improves the capability of your body to use oxygen and it also leads to better blood flow.     2     Exercise increases the production of endorphins(内啡肽) in the brain. The endorphins are responsible for the “feel good” effect you feel and they also provide you with the much-desired “runner's high”. In simple terms, it is the sense of wellbeing people receive after performing the exercise.

    3     How do you choose the best physical activity for your exercise? There is no need for you to be an outstanding athlete or a long-distance runner to achieve stress relief. For instance, you can perform some aerobic exercise (有氧运动) such as jogging and dancing.     4     Doctors can help you develop an effective and safe exercise routine while taking into account your fitness level and the conditions you are suffering from.

Keep in mind that any kind of exercise will improve your fitness and reduce stress levels. You can also combine the activities till you have found the most enjoyable one. If you do not enjoy going near the water, never take swimming as a form of exercise. If the thoughts of running result in making you anxious, do not choose to train for a 5-kilometer race.     5
