问题 单项选择题

某公司一项对员工工作效率的调查测试显示,办公室中白领人员的平均工作效率和室内气温有直接关系。夏季,当气温高于30℃时,无法达到完成最低工作指标的平均效率;而在此温度线之下,气温越低,平均效率越高,只要不低于22℃。冬季,当气温低于5℃时,无法达到完成最低工作指标的平均效率;而在此温度线之上,气温越高,平均效率越高,只要不高于15℃。另外,调查测试显示,车间中蓝领工人的平均工作效率和车间中的气温没有直接关系,只要气温不低于5℃,不高于30℃。 从上述断定推出以下哪项结论最为恰当( )

A.在车间中,如果气温低于5℃,则气温越低,工作效率越低

B.在春秋两季,办公室白领人员的工作效率最高时的室内气温在15℃—22℃之间

C.在夏季,办公室白领人员在室内气温32℃时的平均工作效率低于在气温31℃时

D.在冬季,当室内气温15℃时,办公室白领人员的平均工作效率最高

答案

参考答案:D

解析: 在冬季,当气温低于5℃时,无法达到完成最低工作指标的平均效率;而在此温度线之上,只要不高于15℃,气温越高,平均效率越高。因此,可得出结论:在冬季,当室内气温15℃时,办公室白领人员的平均工作效率最高。其余各项都不能从题干的条件中恰当地得出。

      It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming

up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to

work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of

labor, he returned to find his bike gone.

      The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour

weeks to support his young family. And the bike was also used to get groceries (食品杂货), saving us from

having to walk along long distances from where we live.

      I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story.

Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then

called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an

honor that a complete stranger would go out of their way for someone they have never met before.

      People say that a smile can be passed from one person to another, but acts of kindness from strangers are

even more so. This experience has had a spreading effect in our lives because it strengthened our faith in

humanity (人性) as a whole. And it has influenced us to be more mindful of ways we, too, can share with

others. No matter how big or how small, an act of kindness shows that someone cares. And the results can

be everlasting.
