A | 挂“水壶” 撑“阳伞” 吃“夜宵”杭州日报讯 三伏天,杭城最高气温在35摄氏度以上,人在室外待不住,绿化植物也面临被晒伤、“烤焦”的风险。 The second trial in connection with the death of 23-year-old Elijah McClain following an altercation with Aurora, Colorado, police began Tuesday.Nathan Woodyard was the first police officer on the scene in August 2019 and he put McClain in a carotid hold. He has pleaded not guilty to the charges of manslaughter and criminally negligent homicide.Woodyard's legal representatives declined to comment on the case.In opening arguments, Assistant Attorney General Ann Joyce argued that Woodyard's actions on Aug. 24, 2019, led to McClain's death and were not aligned with his police training, according to ABC affiliate Denver7.McClain told officers during their encounter that he was having trouble breathing and he later choked on his own vomit while he was restrained, the previous trial revealed."This trial is about the defendant and his teammates doing nothing to help Elijah McClain. This trial is about their continued callousness and indifference to Mr. McClain's suffering," she said.Attorney Megan Magdalena Downing, who represents Woodyard, argued that the ketamine that was administered by the EMTs that night was responsible for McClain's death, according to Denver7."Let me be clear — someone is guilty," Downing said. "They're not here. It's not Nathan."McClain was stopped by police on his way home from a convenience store in August 2019. A passerby called 911 to report McClain as acting "sketchy" with a ski mask on; however, the caller said there was no weapon and that no one was in danger at the time.McClain was wearing a ski mask at the time because, according to his family, he had anemia, a blood condition that can make people feel cold more easily.When officers arrived on the scene, they told McClain they had a right to stop him because he was "being suspicious."In police body camera footage, McClain can be heard telling police he was going home and that, "I have a right to go where I am going."Woodyard placed McClain in a carotid hold and he and the other two officers at the scene moved McClain by force to the grass and restrained him.McClain can be heard pleading with officers in police body camera footage, saying he can't breathe correctly."I'm so sorry. I have no gun, I don't do that stuff. I don't do fighting. Why are you taking me?" McClain can be heard saying in body camera footage."I can't breathe," McClain said, according to the body camera footage. He echoed these words several times.When EMTs arrived at the scene, McClain was given a shot of 500 milligrams of ketamine for "rapid tranquilization in order to minimize time struggling," according to department policy, and was loaded into an ambulance where he had a heart attack, according to investigators.McClain was declared brain-dead days later and died on Aug. 30, 2019.McClain's cause of death, which was previously listed as "undetermined," was listed in an amended autopsy report as "complications of ketamine administration following forcible restraint." The manner of death remained listed as "undetermined" as it was in the initial report.In the first trial in connection with McClain's death, officer Randy Roedema was found guilty of criminally negligent homicide and assault in the third degree last week.Another officer, Jason Rosenblatt, was found not guilty on charges of reckless manslaughter, assault in the second degree, and criminally negligent homicide.McClain's mother, Sheneen McClain, walked out of the courtroom with a raised fist after the split verdict and said she was not satisfied with the outcome."America needs to start telling the truth about its history and changing the way it treats all the people that pay into its systems of control," she said in a statement to ABC News on Friday. "Don't say sorry to me for humans that fail even their own kind. My soul still cries out for divine justice for my son Elijah McClain."。

B | 最近,全市河道绿化养护工人陆续启动“抗旱保绿”作业,只为让花草树木平稳度过“烤验”。

C | 针对不同类型的河道绿化,杭州城管部门采取不同方式“保绿”。备塘河樱花林开启“直饮水”模式这两天,备塘河的绿化养护工母师傅与工友们,为河边每棵樱花树都挂上了一只鼓鼓囊囊的绿袋子,上面写着“抗旱滴灌袋”。他数得很清楚,一共挂了132袋,除树干特别小的,河畔其余樱花树都有了自己专属的滴灌袋。不少沿河散步的市民询问绿袋用途,母师傅笑答:“这是给树木自动补水的‘水壶’,可以让我们省点力气。”据了解,备塘河绿化养护班组今年引入的抗旱滴灌袋,每袋容量50升。养护人员灌满水后,只需在袋子底部扎几个小孔,即可持续、稳定地向樱花、樟树等乔木根部输送水分,补水时长可达24小时,如同给树木装上了“直饮水”系统。

D | 相较以往高温天气下,养护工人需每日携带小型水泵、手持水枪往返河道奔波补水的作业模式,如今只需清晨一次性灌满水袋,就能完成当日乔木浇灌工作。有市民好奇,单袋50升的水重达50公斤,是否会压坏树干?对此,备塘河河道管理员小颜解释,养护工安装时会精准选址,尽量选择地面低的一侧竖立水袋,不仅不会压迫枝干,还能起到支撑树干的作用。物理遮阳、错峰作业为绿植撑起“保护伞”树木有专属“水壶”补水,河畔灌木丛则有“遮阳伞”保驾护航。针对无大树遮荫的植物,养护人员在其上方铺盖黑色防晒网,大幅降低叶面温度与地表温度。针对日间高温时段浇水易造成水分快速蒸发,导致红花檵木、麦冬等地被与灌木植物根系被烧伤的问题,养护人员会根据每日气温动态调整作业时间。

E | 目前,所有灌木和地被的抗旱浇水作业,统一调整至每日18时以后开展,避开日间高温暴晒,提升抗旱保绿成效。杭州市综合行政执法局水设施河道中心工作人员提醒,近期气温偏高,河道边绿化带浇水的频次有所增加,如造成市民通行不便,敬请大家谅解。如发现局部绿化出现枯死、晒伤情况,养护人员将尽快处置,全力守护河道生态绿意。
