传统上，急性毒性测试是用作评估在土壤中的污染物对蚯蚓的毒性效应。当评估化学品对蚯蚓的急性毒性效应，最常见的量度测试端点为LC50（即令个别死亡率达50％的浓度）。“LC50”的端点表示在相对较高的污染物浓度的效应，并表示可能有机体造成最大的伤害。在这项研究中，对蚯蚓的LC50为毒死蜱，评估为91.78毫克/公斤（14天），它类似于胡秀清的报告，LC50为83.63毫克/公斤（14天）（胡秀清等人，2004）。根据农药的环境安全评估测试条例，建议的毒性标准是 LC50<1毫克/公斤为高毒农药，1-10毫克/公斤为中等毒性农药，>10毫克/公斤为低毒农药。因此，毒死蜱对蚯蚓急性毒性很低。

原文如下：
Acute toxicity test has been traditionally used to assess the toxicity of contaminants in soils to earthworm. The most common end point measured when evaluating acute toxicity of chemicals to earthworms was LC50 (the concentration that is lethal to 50% of indivials). The endpoint “LC50” shows effects at relatively high pollutant concentrations and indicates the maximum damage likely to an organism. In this research, LC50 on earthworm by chlorpyrifos assessed is 91.78 mg/kg (14 d), which is similar to the report of Hu Xiuqing that LC50 is 83.63mg/kg (14 d) (Hu et al., 2004). According to the regulation of environment safety assessment test for agricultural pesticide, the suggested standard of toxicity is LC50 < 1mg/kg for high-toxic pesticide, 1–10 mg/kg for mid-toxic pesticide, >10 mg/kg for low-toxic pesticide, thus the acute toxicity of chlorpyrifos on earthworms is low.

考虑到蚓茧产量和蚓茧的存活率，可观察到毒性对暴露于毒死蜱的蚯蚓的影响，即使于最低浓度下，产量亦显著下降。繁殖测试结果表明，毒死蜱对蚓茧的产量和蚓茧生的存活率产生负面影响。

原文如下：

Considering cocoon proction and cocoon viability, toxic effects could be observed in earthworms exposed to chlorpyrifos, with significant decreases in reproction at the lowest concentration. Results of the reproction test demonstrated that chlorpyrifos have adverse impact on cocoon proction and cocoon viability.

然而，一些研究表明，由于农药“毒死蜱”长时间存在于土地中，其残留物和代谢物会造成多处土壤、地下水及地表水的污染。（希望有帮助）

大学英语四级考试，即CET-4，College English Test Band 4的缩写，是由国家教育部高等教育司主持版的全国性英语考试。权考试的主要对象是根据教育大纲修完大学英语四级的在校专科生、本科生或研究生。大学英语四、六级标准化考试自1986年末开始筹备，1987年正式实施。

这个测试与上述的急性测试相符，但随著使用的农药浓度的改变，且孵化期亦更长，于测试开始时，给予蚯蚓额外的饲料（5克牛粪末/每测试容器）。进行一系列的实验，以评估幼蚓和成年蚯蚓对测试杀虫剂的反应。

原文如下：
This test conformed to the acute test described above, but as the working concentration of pesticide was changed, and the incubation ration was also longer, additional food (5 g ground cattle ng/test container) was given to the earthworms at test start. A series of experiments were concted to evaluate the responses of juveniles and alt earthworms to the test pesticides.

是我没本事,五月一号我没钱带你去旅游,你以为我想这样的吗?难道假期在家我就不闷吗?重新说明一下,你去不到香港是你的事可不关我的事,我已经在五一之前跟你说过我们不去旅游了,所以你是有足够的时间买船票跟家人去香港玩,就算明天是五月一号,你也可以自己去香港找你家人,都不是很难的事情,但不要每次都把事情弄到我那里,我也不愿意做罪人.整天都想着去旅游散心,你有没有在我的角度为我着想呢?你太自私了.哪怕一个电话的关心都没有,我不想整天都以发信息,发微信,发微博来通讯,打给我一个电话真的那么难吗?没有一个人是奉旨对你好,男人也需要一个懂他的一个女人.我觉得对于一个男人来说我已经对你很好了,做得也很好了,可以说你还是不满足的话,可以直接说出来.不要整天都说爱情怎么样怎么样才是你想要的爱情,但你有没有做好作为一个女人的本责.爱情如果是单一付出的话,这样的爱情很辛苦.这个道理你懂的!可能我也要适当的调整一下自己的心态,对爱情不能太执着,想开一点,不能感觉没有爱情就什么都做不了,男人还是以事业为主比较好,要学会珍惜自己,真想自己开车到别的城市散散心,我也累了。
I know that I am useless. I don't have the money to take you for a vacation on May 1. Do you really think that I wanted it like that? You don't think I am feeling bored as well staying at home on a public holiday? Let me say it again. You couldn't go to Hong Kong, which has nothing to do with me but your own fault. I have already told you before May 1 that we won't be going for a vacation. You have enough time to buy your own tickets and take the family to Hong Kong. Even if tomorrow is May 1, you can still go to visit your family in Hong Kong. It would not be that difficult at all. But everytime you just blame it on me. I don't want to be the guilty one any more. You can only think of going off for a vacation to take your mind away all the time. Have you ever see things from my point of view? You are simply just too selfish! There was never even a concern phone call to me but only all sorts of textings. It is really that difficult of picking up a phone? Sometimes, you just can't take it for granted that everyone will treat you right. A man also needs a woman, who would really understand him and I think as a man, I am already treating you very well and I have done my very best. If you are still not satisfied, then why don't you tell me. Don't just keep on saying what is love and what kind of love that you would like all the time. Have you done your part as a woman then? If love is only a one-sided job, then such love is too hard for me and you should know it very well. May be I should adjust my attitude too. Perhaps, there is no need to be too persistant on love and I should take things more easy. It is not the end of the world when there is no love. I think that to a man, career is still the top priority. I need to learn how to cherish myself and right now, I really wish I could get on a car and drive to the next city to unwind myself because I am also tired!
