  • 1.It is hard for many people to accept changes.However,life is always changing.We might lose our jobs,our loved ones,or have other life-changing things.We might not like the changes,but we can deal with them in an active way.Luckily,there are many ways to face changes,to deal with them and finally accept them.
        It is wise to release(宣泄) the feeling brought by,a change that upsets you.For example,losing your job makes you sad.You can tell others your feelings in a polite way.Also you can ask yourself,"Why am I upset or worried about this change?""What will happen as a result of this change?"Asking yourself these questions can help you think if the change is really worth(值得) worrying about.Besides,though the change can have a bad influence on your life,in most situations you can turn it into a chance to discover your hope for life again.
        Of course,you need to do something so that you can completely accept changes.When the change influences you,you can keep working,trying something you've never done before,or staying with others.In this way,you will make yourself forget worries.It'll help change your life actively for the future.Finding a way to move on and thinking about your future is another important part of accepting changes.You can get a new job or have a long trip.By looking to the future,you'll be able to better deal with the past and accept it as something that had to happen for you to move forward.Besides,make a decision to try to use your power(力量) to make an even better world.In this way,you're accepting the change.

  • 2.About 2,400 years ago in ancient Greece,Aristotle was born.It was a period when the Greeks highly respected great thinkers and teachers,such as Pythagoras,Socrates,Democritus,and Plato.Many historians believe that Aristotle was greater than all of them.
        Aristotle is called "the father of biology."Many of his discoveries are still considered correct today.For example,it was Aristotle who first wrote that dolphins are not fish-through close observation,he had found out that they give birth to their babies rather than laying eggs,and that mother dolphins feed milk to their young.
        Aristotle's way of grouping animals may have been his most important achievement.in biological science.Experts used his system for over 2,000 years.In 1758,a Swedish scientist discovered a new way of grouping animals.Aristotle placed the animals into two groups:those with blood and those without.In fact,his way of grouping,though a little bit different,was approximately the same as the modern grouping system of vertebrates and invertebrates.
        Professor Nardo wrote:"Although Aristotle paid much attention to the importance of evidence(證據(jù)),he failed to realize that doing experiment is almost always the best method of finding it.Yet,when he did simple and basic experiments,Aristotle was able to make mostly correct conclusions."
        He also wrote that"Aristotle's influence on the future growth of knowledge was both negative and positive..." For example,Aristotle believed that the planets went around the Earth ,not the Sun.Because the later scientists believed in him blindly,their progress in astronomy was stopped.However,he added that many of Aristotle's ideas brilliantly provided directions for modern discoveries.

    B.He was the first man to find that dolphins are not fish.
    C.People consider him greater than all the other thinkers.
