《天天快报>报社组织拓展训练,最后一天对所有参加拓展的员工进行考核。如果考核结果达到3分或3分以上,记为优秀,在考核之前,有几个人就成绩讨论起来。陈东说:“小军、小霞身体素质都不错,他们俩至少有一个优秀。”牛力说:“训练的时间太短,大家练习都不够,这次没有人能得优秀。”马方说:“怎么可能呢 有人以前就参加过训练,他们一定能得优秀。”假设这三个人只有一个人的猜测得到了验证,那么一定可以推出以下哪项结论 ()

A.牛力说的对,参加拓展的报社成员没有人得优秀

B.没法确定对错,但所有训练成员都得到优秀

C.马方说的对,有人获得了优秀,但也有人不优秀

D.陈东说的不对,小霞没有得到优秀

答案

参考答案:D

解析: 根据题意可知,牛力与马方的说法是矛盾的,那就必然是一真一假。题干假设三人中只有一人猜对.逐一分析,则陈东所说必然为假,从而推出小军和小霞身体素质都不是优秀的。故选D。

Roosegaarde, an artist and designer from Dutch has thought of a device(装置). He hopes it will make Beijing's sky clear again and help the people with masks breathe fresh air again in Beijing.

An electromagnetic field(电磁场) will pull the dirty particles in the air to the ground, and then they can be easily cleaned.

Roosegaarde says, "It's like when you have a balloon which has static electricity(静电) and your hair goes toward it. Smog happens the same way as the hair."

His workplace has reached an agreement with the Beijing government to test the technology in one of the capital's parks.  Beijing's skies are regularly covered by grey smog. Serious cases of air pollution are often reported in Beijing. Roosegaarde says an indoor test has already shown it works well and he is confident of the results. With the help of a team of scientists and engineers, he is sure that the device can be worked outside.

"Beijing is a very good place to test the device because the smog in Beijing is quite low and there's not so much wind." says Roosegaarde. "We'll be able to make the air pure but the most difficult thing is to remove the smog. As a result, you can see the sun again."

Roosegaarde also reminds us that his aim is not only to give a plan to solve Beijing's dirty air pollution but also to make people pay attention to the environment problem. He adds, "This is not the real answer for smog. The real answer to do with it is clean cars, different industry and different lifestyles. " However, he hopes the project will make the citizens realize the differences between clean air and smog-filled air.
