Every species of plant or tree produces its particular chemicals. B EQ has something to do with your understanding of emotions. It refers to people’s awareness, management and expression of emotions. EQ plays an important role in success. If you are not satisfied with your EQ, you can use the following five ways to improve it. Know your own emotions-Recognise and name the emotions you feel; understand why you feel them; distinguish between feelings and actions and tell yourself what you are feeling. Motivate yourself-You need to consider how to control your feelings productively. Practise some emotional self-control and delay satisfaction. A study found that people who delayed satisfaction were more successful later in life-as measured by a lot of factors including happiness, income and job satisfaction-than those who did not do that. You need to find a balance of emotions and motivate yourself to do something about it. Recognise emotions in others-The ability of listening to another person’s opinions is a skill that effective managers have. Emotionally intelligent persons are also sensitive to other people’s feelings and listen to others well. Manage your emotions-Accept your feelings, but find a balance between oversensitivity and emotional suppression. When you are angry or unhappy, you need to find a way to get out of the mood. It is healthy to express your emotions, rather than keeping them hidden. Handle relationships-Applying conflict management skills instead of ignoring conflicts and being considerate and cooperative are part of controlling relationships. Communication skills are essential to healthy relationships. 查看更多

 

题目列表(包括答案和解析)

When you watch TV programmes about wild animals, it is amazing to see how an antelope can escape a lion’s attack. In the wilderness, everyone has a stunt(绝技). Even plants have their own ways of fighting off enemies.

Over millions of years of evolution, plants have developed a unique defence system. Chemicals are widely used for survival, By making their leaves, flowers, stems, roots and fruits distasteful or poisonous to predators(食肉动物), plants can fight back.

One such plant is the Gold Wattle tree. British botanist David Cameron has found that when an animal eats the tree’s leaves, the amount of poisonous tannin(丹宁酸) increases in the other leaves. “It’s like the damaged leaves telephoning the others telling them to fight together against the enemy,” he said.

The tree also sends defence messages to neighboring plants by giving out a special smell. Golden Wattle tress in the surrounding 45 meters will get the message and produce more tannin within 10 minutes. Now, if a predator eats too many of the trees’ leaves, it will die.

Every species of plant or tree specializes in the production of a particular set of chemicals. A herbivore(草食动物) that can safely eat the leaves of one tree may be poisoned by its neighbor.

In this way, plants have developed not only individual defence systems, but also shared it with others. This makes it impossible for a single predator to destroy even a small area of forest.
