Passage One
In recent years, corporations and governments have developed increasingly sophisticated systems for monitoring and tracking individuals with the goal of protecting public safety. Advocates of these systems have argued that they are essential to combating crime.Now, however, civil libertarians have begun to respond, arguing that these systems significantly intrude upon the privacy of the individual. Weighing the claims of these two groups is complicated by the fact that there is relatively little statistical information on the efficacy of such systems: there are indications that they decrease the crime rate but little evidence that they do so significantly or cost-effectively.
1. According to the passage, what do advocates of monitoring systems argue?
A They are essential to combating crime.
B They allow for more efficient tracking of individuals.
C They are necessary for ensuring public safety.
D They provide statistical information on crime rates.
答案：A
Passage Two
Gender, place of birth, and race are not obvious forces responsible for preventing many women from reaching the top in their areas of endeavour. Rather, the important issue is how these forces conspire together to keep women from critically important networks. If women are not present in large numbers in influential social networks, they will not be given important information, nor will they be given opportunity, recognition, or reward.
1. What does the passage suggest is the result of women's absence from influential social networks?
A They are prevented from reaching the highest levels of their fields.
B They are unable to gain recognition for their work.
C They do not receive important information.
D They are barred from certain professions.
答案：A
Passage Three
Many social scientists have long seen conflict as time-consuming, destructive, and ultimately unnecessary because it prevents the achievement of common goals. Yet conflict can be a positive force in mobilizing individuals and groups to pursue important causes or to achieve change. Conflicts can stimulate creativity and innovation, encourage new ideas, and prevent groupthink.
1. According to the passage, what is true of conflict?
A It is often unnecessary.
B It is always destructive.
C It prevents groupthink.
D It can have positive consequences.
答案：D
