Question

16．I am peter Hodes，a volunteer stem cell courier．Since  March 2012，I've done 89 trips of those，51 have been abroad，I have 42 hours to carry stem cells（干细胞）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（捐献者） to the time they can be implanted in the patient，we've got 72 hours at most，So I am always  conscious of time．
I had one trip last year 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 check-in desk at Providence，the lady on the desk said："Well，I'm really sorry，I've got some bad news for you-there are no fights from 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．re-routed（改道）me through Newark and got me back to the UK even earlier than originally scheduled．
For this courier job，you're consciously aware than that box you're got something that is potentially going to save somebody's life．

Answer 1

分析 我是peter Hodes，是一名志愿运送造血干细胞的送货员．自2012三月以来，我已经输送了89次造血干细胞，有51次是送往国外的．干细胞在我的小箱子里只能存放42小时，因为箱子里面的两个冰包只能维持这么长时间．总之，从干细胞由捐献者体内取出到它们被植入到病人体内，我们最多有72小时的时间，所以我总是有很强的时间观念．
去年在美国，有一次在运送干细胞的路上，我被的一场飓风困住了．在罗得岛州的首府，Providence，我带着干细胞，打算飞往华盛顿然后再回到伦敦机场，但是当我到达 Providence机场的登机手续办理台时，在柜台里的一位女士说："好吧，我真的很抱歉，我得告诉你一些坏消息，没有飞往华盛顿的航班了．"于是我拿出箱子，并把它放在桌子上，说："这个箱子里是病人迫切需要的干细胞，请你必须得让我回到英国．"于是，她放下手头上所有的工作，安排了一架小型飞机为我组织了一次飞行，并为我更改了航线，经由 Newark，使我先于预定的时间到达了英国．
对于这份送货员的工作，你会清醒地意识到你手里的不只是一个装东西的箱子，而是可能会挽救某人生命的东西．

解答 答案：
29．B   词义猜测题  由于"a volunteer stem cell courier"在句中作peter Hodes的同位语，所以courier应该是表示一种职业；根据第一段"I've done 89 trips我已经运送了89次造血干细胞"；"I have 42 hours to carry stem cells干细胞在我的小箱子里只能存放42小时"以及第二段作者讲述了他在运送干细胞时被困的经历；可知作者是运送干细胞的人，即B．delivery man 送货员．A．供应商；C．收藏家；D．医学博士；故选B．
30．D   细节理解题．根据第一段"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．干细胞在我的小箱子里只能存放42小时，因为箱子里面的两个冰包只能维持这么长时间．"可知冰包将不能存放更长的时间．故选D．
31．B   细节理解题．根据第二段"She arranged for a flight on a small plane to be held for me，re-routed me through Newark and got me back to the UK…她安排了一架小型飞机为我组织了一次飞行，并为我更改了航线，经由 Newark，使我先于预定的时间到达了英国．"由此出可知那位女士先将Peter安排在了飞往Newark的航班上；故选B．
