[解析]
(1)推理判断题。根据第一段My wife,Hannah,and I don't usually keep houseplants.Anything in pots gets either overwatered or underwatered,but after my diagnosis with brain cancer,I loved the idea of having something green around.(我妻子Hannah和我通常不养室内植物。花盆里的任何东西要么浇水过多,要么浇水不足,但在我被诊断出患有脑癌之后,我喜欢周围有一些绿色的东西的想法。)可知,作者和妻子Hannah以前种植的植物从来都生长地不太好。而根据第二段When it didn't immediately turn yellow or lose leaves,I was pleasantly surprised.(当它没有立即变黄或落叶时,我感到惊喜。)可判断,作者感到惊讶的原因是这次的幸运竹没有像以前的植物那样糟糕。故选D。
(2)句意理解题。根据第二段As a family physician,I was used to offering care,not receiving it.(作为一名家庭医生,我习惯于提供照顾,而不是接受照顾。)可知,作者以前是一名家庭医生,习惯于照顾他人。而划线句子"Watering the plant,small act as it was,connected me to a core part of my old identity.(给植物浇水,虽然是件小事,却把我和我旧身份的一个核心部分联系在一起。)"可推断,作者所指的旧身份是自己做家庭医生时的照顾他人。故选B。
(3)推理判断题。根据第四段Hannah reminded me that we'd seen houseplants die before,but I couldn't shake the feeling that the plant had become a symbol of my health.I grew increasingly depressed and fearful.(Hannah提醒我,我们以前见过室内植物死去,但我无法摆脱这种感觉,那棵植物已经成为我健康的象征。我变得越来越沮丧和恐惧。)可知,作者感到害怕,因为这种植物的健康状况不佳可能预示着他的死亡。故选A。
(4)细节理解题。根据最后一段Knowing I couldn't control my fate (命运),my anxiety actually lessened.(知道自己无法控制自己的命运后,我的焦虑反而减轻了。)可知,作者感到不那么焦虑是因为作者知道自己无法控制自己的命运,也就是接受了自身的局限性。故选B。
