[不定项选择题]资料：No matter how carefully you pick the members on your team,you may still end up with a negative employee.These workers don’t necessarily fall into the category of “toxic,”but they’re just kind of a drag with their cynical, pessimistic worldview.If you ‘re dealing with a negative employee,here are 3 steps to take.
FIND OUT WHY
If you decide to proceed in addressing the behavior,think about whether there have been behavior changes recently.Is the negativity a constant or has the behavior escalated?If the latter ,was there an event that led up to the change?Individuals in the workplace live multi-dimensional lives,and other non-workplace stresses may impact work productivity and mood.
In an April 2016 report in the Journal of Managerial Psychology,a team of Toronto researchers found that employee who are cynical of their workplace may feel more positive if their managers are supportive.
DISCUSS GOALS
When discussing the situation with your negative employee,it is recommended to frame the discussion in the context of the Individual’s goals.”Tone policing” where you simply point out pessimistic commentary without addressing the root cause, rarely works and may just cause more resentment.Get to the root of the issue and find out if the employee needs additional training,perhaps in management or communication skills,to overcome a deficit.
ADDRESS ISSUES
A direct,solutions-oriented conversation with the employee can uncover problems or circumstances driving the behavior.If there are workplace issue that can be solved,consider doing so if it make sense.If there are personal issues that have caused an escalation in negative behavior,examine whether accommodations can be made to help the person while they’re going through such challenges.Some employees don’t have great interpersonal skills,and putting them in jobs where they are more focused on job-related tasks than on interactions with others can be an effective solution,too.
It can be inferred from the article that
A.If your manager is supportive ,you might feel more positive
B.Negative employees are devastating to the company
C.Raising salaries will make employees feel positive
D.Promotions means a great deal to the employees

Standing on the rim of the Grand Canyon, gazing across this giant wound in the Earth’s surface, a visitor might assume that the canyon had been caused by some ancient convulsion. In fact, the events that produced the canyon, far from being sudden and cataclysmic, simply add up to the slow and orderly process of erosion.
Many millions of years ago the Colorado Plateau in the Grand Canyon area contained 10,000 more feet of rock than it does today and was relatively level. The additional material consisted of some 14 layered formations of rock. In the Grand Canyon-region these layers were largely worn away over the course of millions of years.
Approximately 65 million years ago the plateau’s flat surface in the Grand Canyon area bulged upward from internal pressure; geologists refer to this bulging action as upwarping; it was followed by a general elevation of the whole Colorado Plateau, a process that is still going on. As the plateau gradually rose, sha
