在发展迅速的21世纪,手机已经是每个人的必备品。写信,已经成了过去时,人们都开始依靠手机来干任何事情:信息、微信、QQ、购物、订餐、买房、电话、导航、上网、看电影、追电视剧……但是,手机真的能代表一切吗?
手机,虽然引进发展到能干任何事情的地步,但是,手机必定是手机,辐射还是比平常的电脑和电视要大的多。而写信呢!无辐射,而且自己写的字才是最能表达自己此时此刻最想表达的真情的。还可以练习自己的写字的水平,和写作的.水平。
而手机呢?玩多了可是有害的——据科学家研究表明:手机在使用的过程中会产生电磁辐射,辐射让患脑癌危险增加1倍,每天通话一小时将永久性耳聋;尤其是刚接通电话的那一瞬间,对耳朵的辐射是最大的。电磁辐射的时间越长、音量越大,对耳朵的危害也越大,电磁波的辐射会造成短时间的耳鸣、耳闷、记忆力下降。频繁接听手机将导致白内障啊!恐怖不恐怖,大家还敢玩手机吗?而这只是一个小时的***害,而在日常生活中只会打一个小时电话吗?(我都不打电话的!嘻嘻~)
而两个小时,这种***害真是让人一辈子也不敢再碰手机了——连续手机通话两小时肯定对眼球晶状体有损伤。所以在这里我建议大家不要继续煲“手机粥”,最长的通话时间尽量控制在半小时之内。而长时间对着手机,手机上的辐射可导致老年痴呆,手机挂胸前会影响女性内分泌,手机辐射将降低男性生殖能力手机辐射引发失眠和头痛。可怕的手机啊!
之所以才有这么多人因为玩手机玩多了而死去。就是这个道理啦!所以说:在21世纪的今天,虽然手机十分的普及,但也不能时时刻刻都和手机作伴,要适量的离开手机,和手机说拜拜。不能让手机上的辐射有机可乘。
手机真的是好的吗?
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。
Life has its ups and downs, and only true friends always stay around. Like anyone else, I have got many friends. They often help me when I’m in trouble. Especially, when I fail in an examination, they always care for me and encourage me to study harder. Last year, when I was hurt in a basketball game, my friends took me to the nearby hospital at once and look after me by turns. In my eyes, friends are the most precious wealth that one should treasure all his life.
