问题 Choose the correct letter, A, B, C or D.
Write your answers in boxes 31-33 on your answer sheet.
What does the author say about the natural systems?

选项 A、New technologies are being developed to predict change with precision.
B、Natural systems are often more sophisticated than other systems.
C、Minor alterations may cause natural systems to change dramatically.
D、Technological developments have rendered human being more independent of natural systems.

答案C

解析 利用细节信息“natural systems”定位于原文第八段“Many of the natural systems…they are often very sensitive to the smallest of changes and perturbations,and their behaviorcan flip from one mode to another suddenly and dramatically”。与此信息直接对应的为选项C(“minor alterations”对应原文“smallest of changes and perturbations”,“changedramatically”对应原文“flip from one mode to another suddenly and dramatically”),所以正确答案为C。
