科学是人类对事物认识和研究的活动,也是人探寻客观本质规律的活动。这种说法,却从广义来说,不能将科学与其它社会活动区别开来。因此,人们对科学的定义为:科学是人类的思想认识的理论体系,这种体系与其它认识的理论体系的分别,就在于符合客观世界的规律。所以科学的定义应为:科学是符合客观世界本质的规律的思想理论体系。
这里,科学与其它活动的分别是很清楚的,那就是,它是人的思想认识,是理论,是思想,是意识形态方面的\'东西。
然而,科学与其它思想理论体系,即与其它意识形态的分别,就在于其理论思想符合客观的本质的规律。不符合客观本质规律的思想体系,就不是科学。
第三,科学的理论体系,是系统的,而不是零碎的理论或思想,这科学定义还应加上系统的几字,即科学是是符合客观规律的系统的思想理论体系。人要了解自然或社会,就必须了解得详细,这就有了分门别类的认识和研究,而每一类,就成为了学科。
学科和科学的分别,恰恰仅仅在于前者不一定是符合客观规律的理论体系,后者是符合客观规律的理论体系。
在一个美丽的夏天,爸爸妈妈带我和弟弟去班芙市的洛基山游玩。在路上,我们经过了一片果园,那里果树成荫,栽种着苹果、樱桃等水果。我们来的正是时候,果子成熟了。在苹果园,我们一饱口福,品尝了酸酸甜甜的苹果干和苹果汁,还有香醇的苹果酒。在这儿,我还亲自摘苹果,妈妈拿来梯子,我爬上去,摘了许多苹果,有红的,绿的,还有半红半绿的,叔叔阿姨们用一个大盆子把我从树上扔下来的苹果接住。我们摘了一个又一个苹果,可高兴了。那是我第一次亲手从树上摘下了水果,也是我记忆中最美味的水果。带着丰收的.果实,我们依依不舍地走出了美丽的果园。
第四天,我们终于到了洛基山。虽然是夏天,可从远处看去,山顶依旧被冰雪覆盖,云雾环绕。到了山顶,映入眼帘的是皑皑的白雪,茫茫的冰川,冰雪象水晶一样晶莹洁白。我们穿上了棉衣,坐上雪车,投入了冰川的怀抱,在冰川上嬉戏,那感觉真是特别极了。我和弟弟在厚厚的冰上打了个洞,看到冰水在流动,尝一尝,水甜甜的,和普通的水真的不一样。
The bicycle is the most popular means of transportation in China. China is a country “on bicycle wheels”。 People ride them for various purposes such as going to and from school and work. Bicycles are very cheap and easy to buy in China.

Imagination is the ability to form a mental image of something that is not perceived through the senses. As to the attitude towards imagination, it varies from person to person. Some people think that imagination is good for many things. First, imagination makes it possible to experience a whole world inside the mind. Secondly, imagination has a great role and value in each one’s life.
However, some people hold a negative view on it. They think it does not matter whether you have imagination or not. First, imagination is not practical, which makes people daydreamers. Second, people sometimes do not have to be imaginative in life or work. If they follow the step-by-step schedule, they also would succeed. In their eyes, imagination is a creative power but it is not necessary to achieve success in any field.
As I am concerned, I think we should recognize the importance of the power of the imagination, maintain, and develop our imagination as time steps. Understanding how to use your imagination correctly will put you on the golden path to success, satisfaction, and happiness.
