Which of the following may replace the phrase "trawl through" (Line 3, Para. 2)?
A.Keep track of.
B.Store in.
C.Sift through.
D.Sap into.
参考答案
正确答案:C
解析:语义理解题。trawl through意思是“详细审查”。B store in“存储”;D sap into意思是“逐步侵蚀”,不合题意。选项A 是干扰项,但不可能是追踪记录各个商业和政府的数据库,从“in search of suspicious patterns that might indicate terror plans”可以看出是“审查过滤的意思”。从下文第四段第二句话“sift through the personal information”也可以获得信息。
