UNIT 7课时跟踪检测(五)主题阅读拓展练 一、阅读理解限时练(限时25分钟) A I am Tony, a volunteer stem cell courier.Since March 2019, I have done 99 trips — of those, 56 have been abroad.I have 42 hours to carry stem cells in my little box because I've got two ice packs and that's how long they last.In all, from the time the stem cells are harvested from a donor to the time they can be implanted (移植) in the patient, we've got 72 hours at most.So I am always conscious of time. Last year, I had a trip where I was caught by a hurricane in America.I picked up the stem cells in Providence, Rhode Island, and was meant to fly to Washington then back to London.But when I arrived at the check­in desk at Providence, the lady on the desk said: “Well, I'm really sorry, but I've got some bad news for you — there are no flights to Washington.” So I took my box and put it on the desk and I said, “In this box are some stem cells that are urgently needed for a patient — please, please, you've got to get me back to the United Kingdom.” She just dropped everything.She arranged for a flight on a small plane to be held for me, rerouted (改道) me through Newark and got me back to the UK even earlier than originally scheduled. For this courier job, I'm consciously aware that in that box I've got something that is potentially going to save someone's life. 语篇解读：本文是一篇记叙文。文章主要讲述了作者是一名人体干细胞运送员。通过这份工作作者意识到自己运送的东西有可能拯救别人的生命，所以作者认为自己的工作非常有意义。 1．What does the underlined word “courier” mean in Paragraph 1? A．Provider.　　　　　　 B．Collector. C．Delivery man. D．Medical doctor. 解析：选C　词义猜测题。根据第一段画线词后作者对自己工作的解释可推知，作者应该是一位干细胞运送者，故画线词“courier”意为“送货员”，与C项词义相近。 2．Why does the author have to complete his trip within 42 hours? A．The operation needs that much time. B．The donor can only wait for that long. C．He can't stay away from his job too long. D．The ice can only last such a period of time. 解析：选D　细节理解题。根据第一段中的“I have 42 hours to carry stem cells in my little box because I've got two ice packs and that's how long they last.”可知，作者必须在42小时内完成他的行
