     The time of a baby is born can decide what jobs they will work on in later lives, a new study has

suggested.  

     Being born in a certain month seems to show the statistical (统计学的) likelihood (可能性) of

what job a person will end up with.    

     Researchers have found that the month in which babies are born could also affect everything from 

intelligence (智力) to length (长度)of life.    

     A child born in December is more likely (很可能的) to become a dentist while someone whose 

birthday falls in January will tend to be a debt collector (收账人), they found.    

     A February birth seems to increase the chances of being an artist while March babies seem to

become pilots.    

      Meanwhile, April and May babies are said to have a fairly (公平的,均等的) even spread of jobs;

births in the summer months mean a much lower chance of becoming a high-earning football player,

doctor or dentist.  

     The study was made by researchers who analysed (分析) the birth months of people in 19 different

occupations (职业) using information from the last census (人口普查), the Daily Mail reported.  

     Although these things may be difficult to explain,  relations between birth months and specific health

problems have a scientific basis (依据).

阅读下面的一段文字。并回答后面的题目:


美国科学家近日研制出一种摄像机,它可以把患者静脉的绿色视频图像投射在皮肤上,这一投影与静脉的实际位置基本一致。这样可大大减少因医护人员静脉注射不熟练给患者带来的疼痛。
这台名为“静脉对比度增强仪”的装置用一架近红外线摄像机实时捕捉患者静脉视频图像,围绕摄像机镜头的一排近红外线发光二极管,以740纳米的波长照亮皮肤,这种波长能被血液吸收,被血管周围组织分散。摄像机拍摄的图像被输入个人电脑并用软件处理,该软件将图像实时映射在一个明亮的绿色背景上,并增强静脉和周围组织之间的对比度,个人电脑然后将图像输入到一架投影机,投影机又将图像投射到皮肤上。
为防止出错,这种装置还特别安装了一种叫“热镜”的装置。“热镜”在可见光下是透明的,可以反射红外线波长。视频投影机和摄像机被设定在相互呈90度角面对镜子的位置上,而镜子相对视频投影机和摄像机呈45度角。经校准后,可以保证一条静脉的投影距离其正确位置的误差始终不超过0.06毫米。

红外线发光二极管的作用是( )。

A.照亮皮肤,使皮肤漂亮
B.使摄像机能清楚拍摄
C.照亮皮肤,使皮肤得到治疗
D.使血液吸收740纳米波长的营养
