10．Most people think about donating blood．However，very few actually do it．Even the most consistent ones donate an average of just three to four times during their lifetime．Now the officials in Sweden are trying to change the trend with the help of modern-day technology．
The encouragement to donate again begins shortly after the donor leaves the clinic when he/she receives a"thank you"text．Though that certainly helps them feel appreciated，what is even more pleasing is the text they receive each time their blood is used to help someone in need．
Karolina Wiberg，manager of the Stockholm blood service，believes this small gesture not only results in repeat donors，but helps bring in new ones．The programthat was started in Stockholm has received such positive feedback that it is now being rolled out across the country．
However，Swedish officials are not stopping there．They are also encouraging local clinics to publish the exact levels of the different blood groups they have at any given time on their websites．This allows potential donors to realize that their blood can make a difference in saving someone's life．
While all these outreach（外展服務(wù) ） programs are great，busy citizens，even the ones with the best intentions have to be occasionally reminded．In order to jog their memories，officials ask people for authorization（授權(quán)） to send them text，F(xiàn)acebook，and e-mail reminders．Though that may sound disturbing，the citizens do not seem to mind，given that the messages are light-hearted and fun-things like"We won't give up until you bleed．"
Though Sweden is currently the only country using modern technology to urge more donations，don't be surprised if more join in，especially if the Nordic country's blood banks start to overflow!

分析 本文介紹了瑞典醫(yī)院在獻血者的血液被使用時，會給捐獻者發(fā)生短信通知對方所獻的血正在被使用．這種做法得到了很好的反饋，也獻血者所接受．有可能會讓更多的人加入到獻血者的行列中．
解答 28．B．推理判斷題．根據(jù)第二段第二句Though that…used to help someone in need可知醫(yī)院發(fā)送短信給獻血者的目的就是告訴對方你的血已經(jīng)被使用了．這會讓捐獻者非常高興，可能還會再次獻血．故B正確．
29．C．細節(jié)理解題．根據(jù)第二段第二句Though…to help someone in need．可知當(dāng)獻血者獻的血被使用的時候，醫(yī)院會通過短信告知捐獻者你的血正在被使用．根據(jù)第三段第一句Karolina Wiberg，manager of the Stockholm blood service，believes this small gesture not only results in repeat donors，but helps bring in new ones．可知這一做法不僅讓獻血者重復(fù)獻血，而且還能帶來新的獻血者．所以"the program"就是指給獻血者發(fā)送短信的做法．故C正確．
30．D．推理判斷題．根據(jù)第三段最后一句The program that was started in Stockholm has received such positive feedback that it is now being rolled out across the country．可知這項開始于斯德哥爾摩的做法收到了積極的反饋，現(xiàn)在全國推廣．說明人們對于這些短信提醒的做法是認同的．故D正確．
31．C．推理判斷題．根據(jù)最后一段Though Sweden is currently the only country using modern technology to urge more donations，don't be surprised if more join in，especially if the Nordic （北歐） country's blood banks start to overflow!如果瑞典這個國家的血庫充盈，也就是說有很多人獻血，說明這種做法是很有效的．那么可能很多國家都會采取同樣的方法．故C正確．
點評 本文是一篇科教類閱讀，題目涉及多道細節(jié)理解題，推理判斷題．做題時學(xué)生應(yīng)仔細閱讀原文，把握文章主要內(nèi)容，聯(lián)系文章上下文內(nèi)容并結(jié)合所給選項含義，從中選出正確答案，一定要做到有理有據(jù)，切忌胡亂猜測．
