UNIT1 1.Mention at least three reasons people get angry.What can we do to control our anger? People tend to get angry when treated unfairly.Specifically, we may fly into a rage when we realize we were betrayed by a close friend or tricked by a clerk into buying something unneceary at a high price.When people treat us with contempt, or deliberately ignore us, we may get annoyed.Also, the sight of injustice often fills us with indignation.For instance, when we see a child being bullied by a group of hoodlums, it makes our blood boil.To overcome our anger ,we have two options: to fight or to run.In the case of a small offense, it’s better to walk away and calm down.It is not neceary to explode at a slight provocation.However ,when confronted with a gro injustice or a serious crime ,we need to stand up for ourselves and speak our mind.After venting our anger ,we may feel better.If we keep negative feelings to ourselves ,we will probably feel miserable for along time and regret not taking action.2.Why do people get depreed?

Which plays a bigger role in our lives?Both reason and emotion are important in our lives.Although they are obviously different from each other, they complement each other just the same.Think about it, it is difficult to isolate reason from emotion and vice versa.When one is arguing, one is combining logic with feelings.When a speaker is advocating a principle, the feeling he puts into his voice reinforces his argument.When scientists conduct researches, they may choose an area that is interesting to them.Darwin studied science because he had been fascinated by plants and animals since his childhood.However, in some areas either reason or emotion may play a bigger role.Science students may need more logic than emotion to conduct experiments, while art students tend to rely more on their emotion for creativity.Within a family, people usually cherish the emotional ties between family members.Emotion could be more important than reason when falling in love or trusting a member of one’s family, whereas reason plays an important role when deciding how to educate a child.Together or separate, reason and emotion play critically important roles in our lives.UNIT 2 1.In what ways can people improve their appearance?

An earthquake damages poorly-built structures.A powerful earthquake can destroy even well-constructed buildings.When the buildings fall down, human lives and property are ruined.Aftershocks may cause additional casualties.A heavy death toll, if not dealt with promptly, may be followed by an epidemic.It is difficult to predict earthquake, so we can only take preventive measures.For example, in an area prone to earthquake, we should construct strong, quake-proof buildings.We should also prepare emergency kits that include a torch, first-aid medicines and bandages.We should move out of dangerous quake zones.When an earthquake strikes while we are in a building, we should move outside.If there is no time to leave , we can hide under a strong table
