当新学期来临时,许多学生对新生活表现得很兴奋。在大学,新生快乐地享受着自由。在接下来的四年里,他们希望过着高中描绘的'美好生活。但事实是,大学生活中有很多东西要学。
First, the major knowledge occupies the most important role. As a student, learning knowledge is their job, while many students focus on playing cellphone in the class, or just sleep. They lose interest in studying when they come to the free environment. Mastering the professional skill helps them to be competitive. The sad thing is that most of them can't realize it.
首先,专业知识占据着最重要的角色。作为一名学生,学习知识是他们的工作,而很多学生在课堂上玩手机,或者睡觉。当他们来到自由的环境后对学习失去了兴趣。掌握专业技能帮助他们提高竞争力,可悲的是,大多数人没有意识到这一点。
Second, as there is much free time, they can make use of it and gain the valuable experience. Students can join some clubs to develop more interest, or find part-time jobs. It is better than to stay in the dorm and play computer games all the time.
第二,由于空闲时间多,他们可以充分利用好这些时间,并从中获得宝贵的经验。学生可以参加一些活动来发展更多的兴趣爱好,或找份兼职工作。比呆在宿舍玩电脑游戏好多了。
A lot of students feel lost in the campus, because they don't plan campus life well. The things you learn will make you different in the future.
很多学生因为没有计划好校园生活在所以迷失了。所学到的东西会让你在未来有所作为。
答案很明确:不是。为什么呢?衣服有什么用呢?我上网搜索了一下得出了答案:
人是炉子!我们已经知道我们吃下去的食物——这就是劈柴,它在我们的身体里燃烧。这时候什么火花也没有看见,我们说它在燃烧,只是因为我们身体里感觉到热。
主要观点:人吃下去的食物,会在体内被人体消化吸收,给人体提供热量,因此每时每刻人体都在产生热量。
但为什么穿上衣服才感到温暖呢?
人是恒温动物,每时每刻都在散发热量,然后热量进入衣服和体表间的空气层,而衣服保证了带有热量的空气不流失,从而保证了体表的温度。
高温物体会向低温物体传递热量,温度差越大传递越快。当身体温度高于外界空气温度时自然会向空气传递热量当然穿衣服也会向衣服传递热量,不同的是空气是流动的它会不停的从你身上吸走热量,当你穿上衣服后你的身体会传递热量给衣服衣服上的温度就会上升,温差减小传递速度也就会减慢这样人就会感到温暖。也就是说我们筑了厚厚的墙壁,冬天还安上双重的窗,还在门上包上毡。我们穿衣服也正是同样的`原因。不让我们身体的热量散失到室内的空气里或者到街上去,我们使衣服暖和,它把我们的热量保持在我们身体周圄。我们的衣服当然也要向外散热,可是比我们身体散热慢得多。
主要观点:身体本身散发热量,而衣服可以来保存这些热量让人觉得温暖。
说白了,衣服就是一堵墙,在我们冷了的时候帮我们“遮风挡雨”,让我们温暖。
挑战自然、挑战生命极限的勇气不是每个人都拥有的,因而我们会仰视它。然而,勇气的代价是什么呢?也许它的背后只是光荣所要连带的艰辛,也许它的背后蕴藏着层层危机,有的甚至会使你丧命。
不论什么时候我们也不可小视自然界,看似“温柔”的它有时也会轻易地夺去我们的生命。北京大学山鹰社学生攀登珠峰不幸遭遇雪崩,可可西里自然保护区索南达杰保护站发生的青年志愿者冻死事件……听到这样的消息我们不禁会感到惋惜,多么年轻的生命,却被毫不留情地吞噬了。但这些悲惨事情的发生却又像警钟一样提醒了我们:年轻与勇气并不代表可以征服一切,想要挑战自然,不能仅凭勇气与热情,更需要丰富的阅历和经验。
是的,伟大的航海家总是从一名普通的水手逐渐成长起来的。这期间的过程可以看作是大海对他的锤炼,让他懂得什么是危险,怎样去克服危险。当多年的航海经验的积累到一定程度时,他才可能做一名真正勇敢的船长,去实现征服大海的理想。这种磨炼是不可省的,任何征服自然的勇气只有建立在牢固的基础上才具有力量,否则你的勇气只能算作一种冲动,会被大自然轻易地消释。
生命本身就是珍贵的,真正的勇气不会置自己的性命于不顾,而去做那些徒劳的牺牲。探险不等于冒险,也许我们每个人心中都会有探索自然的'向往,但这需要理性的支持。所以,我们就必须认真思考后再行事,不要将一时的冲动当作是可以支持整个人生精神力量的勇气。年轻的北大学子们可能平时比较爱好攀登,参加这类活动也比较多,但这离攀登真正的险峰还有很长的距离,敢于作出这样的挑战固然可敬,但不能视生命为儿戏,连许多登山专家都要认真准备才能攻克的险峰,岂是凭你那点经验和知识所能征服的?
总之,有勇气是挑战自然的必要条件,但绝不是全部,实力和经验才是最关键的。
A thing makes me happy sad
Happy winter vacation has gone, I received new one term, but an in winter vacation thing since one after-thought, make me happy sad.
Happy is our home has a lot of Xiaobai rabbit, I chose from its, it has the palm only so big, the eye is aglow, ear is very big very big, he and I played very long, also produced feeling, she is eating when feeding, mouth easily easily still can sound sometimes come.

Do you ever watch movies from other countries? Whenever I do, I think about how similar people really are all around the world. Even though the cultures and languages in those movies are different from mine, people all around the world are alike in their goals and emotions.
One time, I saw a movie made in china that showed parents helping their children with their homework. . My parents helped me the same way. Another time I saw a movie from Argentina. It showed school children playing hide and seek, which is a game I used to play with my friends during recess. Seeing these films demonstrated to me that education is a common goal in every country. Parents want their children to learn so their lives will improve. It also showed me that children in schools everywhere wants to play with their friends. Sometimes the games are similar to ours and sometimes they’re different. Still, they all have the common purpose of fun and learning to work together.
Earning a living is another common goal. I’ve often seen that in movies about other countries. In some countries, people choose their careers from what they like and are good at. In other countries, careers are chosen for them following the traditions of their families. But in every country it seems that people care a great deal about earning a living, and working hard is respected.
Showing people having fun together is always an important part of any movies, no matter what country it comes from. People everywhere want to be entertained, and want to spend time with their families and friends. Different cultures sometimes enjoy different activities, but all cultures enjoy some form of sports, music and dancing.
The movies I’ve seen make it clear to me that no matter the cultural differences between countries, people everywhere have the same basic needs and goals.
