　　1.D 　　2.A 　　3.C 　　4.C 　　分析：　　中国有句古语云：一心不可二用。而最近的一项研究就表明。那些经常一心多用的人往往就是同时做两件事做的最糟糕的人。正是因为不能专注于一件事，才会同时多做几件事，结果可想而知。　　1.细节理解题。根据全文第一句话可知，一心多用，往往会把事情做得更糟糕。故选D。　　2.细节理解题。根据第二段最后一句话可知，然后他们要这些学生一面做一些数学运算一面记忆一组字母用这个很刁难的方法来测试这些学生一心多用的能力。和A项意思一致。　　3.细节理解题。根据全文第二句的butbecausetheyareeasilydistracted(分心)andcan’tfocusononeactivity.可知，许多人一心多用并不是因为他们想要增强工作生产量而是因为他们很容易分心或是不能专注于做一件事。故选C。　　4.推理判断题。由最后一段的Peoplewhoaremultitaskingaregenerallylesssensitivetoriskysituations.一心多用的人一般对危险的情形不太敏感。可知，对危险的事情，一心多用者往往对潜在的危险不能迅速判断。故选C。　　考点：　　科普类阅读。
