傳統上，急性毒性測試是用作評估在土壤中的污染物對蚯蚓的毒性效應。當評估化學品對蚯蚓的急性毒性效應，最常見的量度測試端點為LC50（即令個別死亡率達50％的濃度）。「LC50」的端點表示在相對較高的污染物濃度的效應，並表示可能有機體造成最大的傷害。在這項研究中，對蚯蚓的LC50為毒死蜱，評估為91.78毫克/公斤（14天），它類似於胡秀清的報告，LC50為83.63毫克/公斤（14天）（胡秀清等人，2004）。根據農葯的環境安全評估測試條例，建議的毒性標準是 LC50<1毫克/公斤為高毒農葯，1-10毫克/公斤為中等毒性農葯，>10毫克/公斤為低毒農葯。因此，毒死蜱對蚯蚓急性毒性很低。

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.

考慮到蚓繭產量和蚓繭的存活率，可觀察到毒性對暴露於毒死蜱的蚯蚓的影響，即使於最低濃度下，產量亦顯著下降。繁殖測試結果表明，毒死蜱對蚓繭的產量和蚓繭生的存活率產生負面影響。

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.

2.3 Toxicity of chlorpyrifos on the avoidance response of E. fetida

然而，一些研究表明，由於農葯「毒死蜱」長時間存在於土地中，其殘留物和代謝物會造成多處土壤、地下水及地表水的污染。（希望有幫助）

大學英語四級考試，即CET-4，College English Test Band 4的縮寫，是由國家教育部高等教育司主持版的全國性英語考試。權考試的主要對象是根據教育大綱修完大學英語四級的在校專科生、本科生或研究生。大學英語四、六級標准化考試自1986年末開始籌備，1987年正式實施。

大學英語考試根據理工科本科和文理科本科用的兩個《大學英語教學大綱》，由教育部（原國家教育委員會）高等教育司組織的全國統一的單科性標准化教學考試，分大學英語四級考試（CET-4）和大學英語六級考試（CET-6）兩種。

每年考試過後8月份或9月份公布成績並頒發成績單，根據教育部規定四六級考試不設置及格線，四級425分(含425分)以上可以報考六級，所以大家普遍認為四六級的合格線為425分。英語四六級的分數是排位分，沒有總分。報名時間CET全國英語四六級考試的考試時間為：每年6月份、12月份（每年時間略有不同）。

這個測試與上述的急性測試相符，但隨著使用的農葯濃度的改變，且孵化期亦更長，於測試開始時，給予蚯蚓額外的飼料（5克牛糞末/每測試容器）。進行一系列的實驗，以評估幼蚓和成年蚯蚓對測試殺蟲劑的反應。

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.

是我沒本事,五月一號我沒錢帶你去旅遊,你以為我想這樣的嗎?難道假期在家我就不悶嗎?重新說明一下,你去不到香港是你的事可不關我的事,我已經在五一之前跟你說過我們不去旅遊了,所以你是有足夠的時間買船票跟家人去香港玩,就算明天是五月一號,你也可以自己去香港找你家人,都不是很難的事情,但不要每次都把事情弄到我那裡,我也不願意做罪人.整天都想著去旅遊散心,你有沒有在我的角度為我著想呢?你太自私了.哪怕一個電話的關心都沒有,我不想整天都以發信息,發微信,發微博來通訊,打給我一個電話真的那麼難嗎?沒有一個人是奉旨對你好,男人也需要一個懂他的一個女人.我覺得對於一個男人來說我已經對你很好了,做得也很好了,可以說你還是不滿足的話,可以直接說出來.不要整天都說愛情怎麼樣怎麼樣才是你想要的愛情,但你有沒有做好作為一個女人的本責.愛情如果是單一付出的話,這樣的愛情很辛苦.這個道理你懂的!可能我也要適當的調整一下自己的心態,對愛情不能太執著,想開一點,不能感覺沒有愛情就什麼都做不了,男人還是以事業為主比較好,要學會珍惜自己,真想自己開車到別的城市散散心,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!
