单选题 Questions are based on the following passage.
Everyone arriving at a hospital's emergency room ( ER)' wishes to be seen quickly, but for stroke patients it can be a matter of life or death．The most common stroke involves a blood clot blocking vessels in the brain, killing brain cells nearby almost immediately．Luckily, an effective treatment exists．Thrombolytic (溶解血栓的) therapy uses drugs to dissolve the clot and restore the flow of blood．If started within a couple of hours of a stroke occurring, it can limit brain damage and reduce long-term disability．Neurologists even have a catchphrase for this: "time is brain".
Understandably, hospitals strive to identify stroke cases and administer such medication without delay．A key step is using a computed tomography (CT) scanner to ensure that there has been no bleeding in the brain, in which case thrombolytic drugs would make things worse．The last couple of decades have seen many innovations in reducing this "time to CT".
But in shaving seconds from medical procedures, researchers may have neglected something more important:, the human element．Gal Ifergane, a neurologist at Soroka University Medical Centre in southern Israel, noticed that stroke patients who were accompanied to the ER by friends or family seemed to fare better than those who arrived alone．So for 15 months, ER staff at Soroka recorded the number of companions escorting each stroke sufferer, over 700 in all, and tracked their progress.
The results, recently published in Medicine, tell a striking story．Stroke victims arriving with someone were more than twice as likely to be correctly diagnosed by the triage nurse, and had their CT scans performed earlier．Patients eligible for clot-busting medication also received it much faster if accompanied, although their numbers were too few for the researchers to be sure it was because they had company．The differences were far from trivial．Patients with one companion had CT scans an average of 15 minutes sooner than those unaccompanied．A second companion shaved a further 20 minutes off the walt, although three or more companions did not confer any additional benefit.
Dr．ffergane did not record who the companions were, however, or how they were able to reduce delays．He believes that it is probably a combination of focusing the attention of clinical staff on their loved ones, and providing basic care such as helping to move patients into bed.
Dr．ffergane admits that his study has limitations．The sample size was rather small and his findings may reflect cultural norms in Israel that do not apply elsewhere．But he has already tried to make changes in the way the Soroka University Medical Centre operates．"We asked our security team to allow two people to come in with stroke patients rather than just one," he says．"And we now consider stroke patients who are coming alone as a group at risk．"
Dr．Ifergane also recommends that ERs provide a friendly "stroke liaison" to accompany lone patients during the diagnostic and treatment processes．Something other hospitals might think about, too.
What does the author mean by "time is brain" ?

A．Time is almost as precious as brain.
B．Brain damage should be repaired soon.
C．Doctors need time to study brain.
D．Stroke need to be treated in the shortest time..

参考答案D

解析:
每一个到医院急诊室的人本希望能快些就诊，但对于中风病人而言这关乎着生死一最普通的中风涉及血栓阻塞脑部血管，几乎瞬间就可令周圉的脑细胞死亡：幸运的是，现在有一种有效的治疗方法=血栓溶解疗法使用药物溶解血栓。并且恢复血液流通=(61)如果在中风发作后的几个小时内开始治疗，就可以将脑部损伤控制在一定程度并减少长期伤残：神经科医生对此葚至有一巧名言：。时同就是大脑 ”：
可以理解，医院会尽力识别中风病例，并尽快安排治疗。（62）一个关键步骤是使用计算机断层扫描(CT)来确保脑部没有出血，一旦脑部出血溶栓药物会让病情恶化=在过去的几十军千，已有多种创新方法莱缩短等待减少医疗程序的时间方面，研究者可能忽视了某些很重要的事情：人为因素=(63．1)以色列南部索罗卡大学医疗中心的神经科专家盖尔·伊孚格思注意到，中风病人如有家人或朋友的陪同前往急诊室，比独百丽往进展
的就医进展情况。
(65．1)近期发表在《医药》杂志上的研究结果揭示了一个惊人的事实二有人陪同就诊的中风病患得到分诊护士正确诊断的几率高出两倍以上，也可更早地接受CT检查：如果有人陪同，能够接受血栓崩解治疗的病患也可旱些得到治疗，尽管其数量偏少，不足以令研究者确信是否是陪同发挥的作用：而有无陪同的差别就大了很多。有一人陪同的病惠比无人陪同的病患能提早15分钟接受CT检查。(63—2)而第二名陪同者则可以再省去20分钟的等待时间，但三名或更多的陪同者则不会再带来进一步的优势。然而，衣服戈恩医生并未记录下陪同者的身份或他们是如何减少等待时间的。他相信或许是陪同者反复地让诊所的工作人员注意到自己的亲人，并提供了诸如帮助病人上床等基本的看护。
伊孚格恩医生承认他的研究存在局限性。样本规模太小，并且他的发现可能只是反映出以色列本地的文化常规，而不适用于其他地区。但是，他已经开始着手改变索罗卡大学医疗中心的运作方式了。“我们让保安小组允许两名而不是一名陪同者跟随中风病人进入医院，”他说道，“并且我们将独自就诊的中风病人视为高危人群。”
(64)(65．2)伊孚格恩医生建议急诊室为单独就诊的病人在其诊断和治疗期间提供一名友好的“中风联系人”。(65-3)这些事情其他医院也可以考虑推行。
定位：由题干中的“time is brain”定位到首段最后两句：Ⅱstarted within a couple of hours of a stoke occuning，it can limit brain damage and reduce lon9—term disability．Neurologists even have a catchpre for this：“time is brain”．
详解：语义理解题。定位句指出，如果在中风发生后的几个小时之内开始治疗，就可以将脑部损伤控制在一定程度并减少长期伤残，神经科医生因此才说“时间就是大脑”。由此可见，这句话是指，中风需要在最短的时间内进行治疗，故答案为D.。A.“时间几乎与大脑一样珍贵”，文中并没有将时间和大脑进行比较，故排除；B.“脑部损伤应该能很快得到修复”，本段倒数第二句提到的是尽量减少脑部损伤，并未提及修复的问题，故排除；C.“医生需要时间研究脑部”，本段都是围绕中风治疗展开的，不涉及研究问题，C.与文意不符，故排除。
