Trevor, C. O., Lansford, B. and Black, J. W., 2004, "Employee turnover (人事变更) and job performance: monitoring the influences of salary growth and promotion", Journal of Armchair Psychology, vol. 113, no.1, pp. 56-64.
In this article Trevor et al. review the influences of pay and job opportunities in respect of job performance, turnover rates and employees' job attitude. The authors use data gained through organizational surveys of blue-chip companies in Vancouver, Canada to try to identify the main cause of employee turnover and whether it is linked to salary growth. Their research focuses on assessing a range of pay structures such as pay for performance and organizational reward plans. The article is useful as Trevor et al. suggest that there are numerous reasons for employee turnover and a variety of differences in employees' job attitude and performance. The main limitation of the article is that the survey sample was restricted to mid-level management, thus the authors indicate that further, more extensive research needs to be undertaken to develop a more in-depth understanding of employee turnover and job performance. As this article was published in a professional journal, the findings can be considered reliable. It will be useful additional information for the research on pay structures. | The following card includes a brief summary and a short assessment of a research paper. It can provide a guide for further reading on the topic.
69. The research paper published is primarily concerned with
A. the way of preventing employee turnover
B. methods of improving employee performance
C. factors affecting employee turnover and performance
D. pay structures based on employee performance
70. As is mentioned in the card, the limitation of the research paper mainly lies in that .
A. the data analysis is hardly reliable
B. the research sample is not wide enough
C. the findings are of no practical value
D. the research method is out-of-date
71. Who might be most interested in this piece of information?
A. Job hunters.
B. Employees in blue-chip companies.
C. Mid-level managers.
D. Researchers on employee turnover.
69. C. 逻辑推理题。通读全文可知这篇文章介绍的是影响人事变更和工作表现的一些因素。
70. B. 从文中“the survey sample was restricted to mid-level management (此次调查只局限于中层管理人员）”可知答案为B。
71. D.

The 2012 London Olympics had enough problems to worry about. But one more has just been added - a communications blackout caused by solar storms.
After a period of calm within the Sun, scientists have detected the signs of a flesh cycle of sunspots that could peak in 2012, just in time for the arrival of the Olympic torch in London.
Now scientists believe that this peak could result in vast solar explosions that could throw billions of tons of charged matter towards the Earth, causing strong solar storms that could jam the telecommunications satellites and interact links sending five Olympic broadcast from London.
"The Sun's activity has a strong influence on the Earth. The Olympics could be in the middle of the next solar maximum which could affect the functions of communications satellites," said Professor Richard Harrison, head of space physics at the Rutherford Appleton Laboratory in Oxfordshire.
At the peak of the cycle, violent outbursts called coronal mass ejections (日冕物质抛射) occur in the Sun's atmosphere, throwing out great quantities of electrically-charged matter. " A coronal mass ejection can carry a billion tons of solar material into space at over a million kilometres per hour. Such events can expose astronauts to a deadly amount, can disable satellites, cause power failures on Earth and disturb communications," Professor Harrison added. The risk is greatest during a solar maximum when there is the greatest number of sunspots.
Next week in America, NASA is scheduled to launch a satellite for monitoring solar activity called the Solar Dynamics Observatory (SDO), which will take images of the Sun that are 10 times clearer than the most advanced televisions available.
The Rutherford Appleton Laboratory helped to make the high-tech cameras that will capture images of the solar flares (太阳耀斑) and explosions as they occur.
Professor Richard Hold away, the lab's director, said that the SDO should be able to provide early warning of a solar flare or explosion big enough to affect satellite communications on Earth "If we have advance warning, we'll be able to reduce the damage. What you don't want is things switching off for a week with no idea of what's caused the problem," he said.
72. The phrase "communications blackout" in paragraph 1 most probably refers to during the 2012 Olympics.
A. the extinguishing of the Olympic torch
B. the collapse of broadcasting systems
C. the transportation breakdown in London
D. the destruction of weather satellites
73. What can be inferred about the solar activity described in the passage?
A. The most fatal matter from the corona falls onto Earth.
B. The solar storm peak occurs in the middle of each cycle.
C. It takes several seconds for the charged matter to reach Earth.
D. The number of sunspots declines after coronal mass ejections.
74. According to the passage, NASA will launch a satellite to _________.
A. take images of the solar system B. provide early warning of thunderstorms
C. keep track of solar activities D. improve the communications on Earth
75. Which of the following might be the best title of the passage?
A. Solar Storms: An Invisible Killer
B. Solar Storms: Earth Environment in Danger
C. Solar Storms: Threatening the Human Race
D. Solar Storms: Human Activities to Be Troubled
72. B. 此题线索为第二三段的内容。
73. D.
74. C. 可从文章第六段直接得出答案。
75. D. 通读全文可知整篇文章讨论的是太阳运动所可能会带来的困扰。
