[单项选择]{{B}}Passage 3{{/B}}
The first navigational lights in the New World were probably lanterns hung at harbor en- trances. The first lighthouse was put up by the Massachusetts Bay Colony in 1716 on Little Brew- stet Island at the entrance to Boston Harbor. Paid for and maintained by "light dues" levied (征收) on ships, the original beacon was blown up in 1776. Until then there were only a dozen or so true lighthouses in the colonies. Little over a century later, there were 700 lighthouses.
The first eight lanterns erected on the West Coast in the 1850’s featured the same basic New England design: a Cape Cod dwelling with the tower rising from the center or standing close by.

[单项选择]
Advances in surveillance technology could seriously damage individual privacy unless drastic measures are taken to protect personal data, scientists have said. Richard Thomas, the Information Commissioner, gave warning last year that Britain was "sleepwalking" into a surveillance society. Yesterday the country’s leading engineers developed the theme, fleshing out a dystopian vision that not even George Orwell could have predicted.
They said that travel passes, supermarket loyalty cards and mobile phones could be used to track individuals’ every move. They also predicted that CCTV (close-circuit television) footage could become available for public consumption and that terrorists could hijack the biometric chips in passports and rig them up as a trigger for explosives.
The report by the Royal Academy of Engineering, Dilemmas of Privacy a

[单项选择]Stress is becoming an increasingly common feature of the workplace. Stress is a highly individual reaction, which varies considerably from person to person, and it is difficult for some employees to avoid it. Undoubtedly, changes in working conditions have led to greater pressure at work at all levels.
However, stress in itself is not harmful. Everyone needs a certain level of stress to enable him or her to feel motivated and to perform effectively. A complete absence of stress can be as damaging as overstress, since it can make people lose interest in their work, and even lead to depression. The difficulties occur when the amount of stress rises above a level which is healthy for a particular individual.
While it may not always be possible to prevent stress, there are a number of ways in which it can be controlled. The first thing that the trainees learn is how to manage their time effectively. This involves, first of all, setting realistic goals for both the short and long
A. A demand is refused.

C. There are changes in living conditions.
D. There are changes in working conditions.
