从实际情况来看,当前农民的文化素质水平依然较低,所以在农作物的病虫害防治方面,依然没有用药的常识以及长远的眼光,过度看重眼前的利益,完全不管不顾农药过度使用造成的环境污染等问题,只看中眼前的产量以及经济效益。所以在农作物的种植过程中,出现了很多关于化学农药使用导致的问题。
(一)滥用已禁止销售的化学农药。
诸如甲胺磷、滴滴涕、二溴氯乙烷等因为毒性过大而被我国禁止使用的农药,农民无视国家的相关规定,因为其具有较好的***虫效果,所以依然在违规大量使用。对于这些高毒性的农药所造成的环境污染,则持无视的态度。
(二)对于农药的使用不够科学和规范。
农民本身存在文化程度和认知水平不足的问题,所以在农作物出现病虫害的时候,农民便会随便的喷洒农药,这就导致农药的用量也许已经超过了使用标准数倍,但是因为没有实现对症下药,所以导致无法达到所期待的效果,而且害虫本身会快速的产生该农药的抗药性,进而出现害虫数量激增,并且能够***灭害虫的特效药越来越少的情况。
(三)对于农药施用后的安全时间没有概念。
农药的施用势必会出现残留的情况,而随着时间的推移,农作物的农药残留量会逐渐的减少,而这个时间也就是农药所谓的安全时间,不同的农药的安全时间不完全相同,农药包装基本都有标明具体的安全时间,但是为了能够使得农作物可以更快的上市,且农民本身对于农药的安全时间概念的认识就不够深入,所以在作物即将上市的时候,农民依然在喷洒农药,这就导致作物的农药残留量严重的超标,对人体的健康产生了非常严重的威胁。
To see a world in a grain of sand,
And a heaven in a wild flower,
Hold infinity in the palm of your hand,
And eternity in an hour.
一沙一世界,
一花一天堂,
手中即无限,
永恒亦短暂。
to prevent H7N9 we should know some common sense. First of all, it is important for us to prevent H7N9 from ourselves. For example, clean our hands frequently.
Sencondly, do more exercises. Such as running. Lastly, change our diet to keep balence. For example, eat more types of vegetables and drink more water
Withthe rapidly development of electronic technology, the paperless office isbasically realized. We have fewer and fewer opportunities to write, as aresult, we always forget how to write the characters. Moreover, the casualexpression from internet makes us confused about the real meaning of theChinese characters. some people think that while we already have a convenienceway to express ourselves, we do not need to write anymore, well,i could not agree with that.
随着科技的高速发展,无纸化办公室基本实现了。我们有越来越少的机会去写字,结果,我们常常忘记怎样去写字了。再者,网络上出现的随意的表达方式让我们对汉字的正解更迷惘。有些人认为我们都有那么方便的方式来表达自我了,为什么还要继续写字,我不同意这个观点。
Becausethe cell phone has shortcut input method and the computer typing could correcterror automatically, this can not be the reason to refuse to write. In the firstplace, Chinese characters has been used for over 6000 years, it is the spiritand soul of a nation, we should be proud of it rather than not to write itanymore.
就因为手机有快捷输入方式,电脑输入有自动纠错,这不能成为我们拒绝写字的理由。第一,汉字已经被使用了近6000年,是民族的精神和灵魂,我们应该为此自豪而不是不想再写它。
Inthe second place, we could cultivate ourselves when we are writing. Forinstance, masterful calligraphy can be rated as superb works of art, we feelsomething special link to art while we are writing. It is this magical thing thatelectronic technology can not do.
第二,我们写字的时候能够修养身心。例如,高超的书法被视为一种艺术,我们写书法的时候会感受到艺术的气息。这种神奇的事物是科技做不来的。
Inthe third place, even though the technology bring us great convenience, westill in the situation that have to write. It could be embarrassing that youforget how to write when you were asked.
第三,尽管科技给我们带来极大的便利,我们有时候还是要写字的。如果我们被问字怎么写的时候,忘记怎么写,那是很尴尬的。
Finally, Chinese characters are our spirit of culture, we shouldremember how to write it, and write it good.
最后,汉字是我们的文化精神,我们应该记着怎么写,还要写好它。
化学农药因为其效果显著、应用直接、起效迅速以及所需投入较少,所以在农作物的害虫防治方面,一直是广大农民的首选。但是因为化学农药被大量的应用,所以使得害虫逐渐对于农药产生了抗药性,在此情况下,只有继续提升农药的使用量,才能够达到防治农作物害虫的目的,但越来越大的农药使用剂量,对于环境、生态以及人类自身的身体健康都产生了非常严重的影响。
(一)农药残留对环境产生污染。
对作物采用农药***虫的时候,农药种只有很少的一部分作用到害虫身上,起到***虫的作用,绝大部分的农药都会被固定在水源、土壤中,直接严重污染周边的环境。
(二)农药打破周边的生态平衡关系。
农药的应用的确能解决虫害问题,但是在***死相关害虫的.同时,周边有益的动物也会受到严重的影响,甚至会导致部分有益动物在一定区域内灭绝,严重的损害当地的生态平衡。
(三)农药对人类自身健康产生严重危害。
由于化学农药的使用剂量在不断的增加,所以这种对农药的过度使用会导致农作物中残留大量的农药,当浓度高于一定程度后,使用后会直接导致中毒的情况出现。而且上文中所提到的被固定在水源以及植物中的农药,会通过食物链关系逐渐在人的体内富集,逐渐引起人类的多种慢性疾病。
When students finish their high school, most of them will to go study in college, the first thing they do is to choose the major. Choosing the major is a big problem for every college student, not only for Chinese students, but also for the students around the world. Students will face the factors such as their interest is more important or the future of the major worth being first concerned.
当学生读完高中,大部分人会去大学学习,他们要做的第一件事就是选择专业。选择专业是对每个大学生来讲都是件大事,并不仅仅对于中国的学生,对于全世界的学生来说都一样。学生仍然面临着他们的兴趣更重要还是专业的将来更重要的问题。
On the one hand, most parents care about the future of the major. When students decide the major, parents will interfere with their own opinion, they want their children can have a bring future, so they care much about the needed talent of the society. Thus the children can find a promising job and earn more money.
一方面,大部分父母关注专业的未来。当学生选择专业时,父母会干涉,他们想要孩子有一个光明的未来,所以他们很关注社会需要什么样的'人才。这样孩子可以找到一份有前途的工作,赚更多的钱。
On the other hand, students want to choose the major that they are interested. This is often contradicting with their parents’ opinion. Some students want to learn art, but most parents won’t be allowed it because it is hard for students to find a job. Everyone admits that interest is the first factor, with it, students will feel happy.
另一方面,学生想要选择他们感兴趣的专业。这经常和父母的意见相左。一些学生想要学艺术,但是大部分父母不会同意,因为这很难让学生找到工作。每个人都觉得兴趣是第一个要素,有了兴趣,学生才会感到快乐。
When choosing the major, students should considerate their parents’ opinion, most parents are open-minded, they will respect the kids’ willingness.
当选择专业的时候,学生应该考虑他们父母的意见,大部分父母是开明的,他们会尊重孩子的意愿。
