【题目】 层云是在大气稳定的条件下,水汽凝结或由雾抬升而成,分布不高且厚度不大。层云常在太阳升起后气温逐渐回升,稳定层被破坏后逐渐消散。根据材料完成下面小题。

1层云易消散但在一定条件下亦可维持数日。在四川盆地上空,层云维持日数较长的季节最可能出现在( )

A.春季B.夏季C.秋季D.冬季

2天空出现层云时可能出现的天气现象是( )

A.①③⑤B.①②⑥C.②④⑥D.③④⑤

【答案】

1D

2B

【解析】

1

由题中“层云是在大气稳定的条件下,水汽凝结或由雾抬升而成”可知,出现层云时风力较小,四川盆地为亚热带季风气候,受山脉阻挡冬季风,冬季风力较小,气温相对较低,水蒸气易凝结成雾,大气稳定不易消散,D正确。其他季节受南风影响,风力较大,层云不易维持,ABC错误。故选D

2

天空出现层云时,大气稳定,无强烈对流运动,不可能出现强对流引起的③大风、④雷暴、⑤冰雹天气,ACD错误。大气稳定,可能出现①细雨、②小雪或⑥晴天,B正确。故选B

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

On November 18, 1995, Itzhak Perlman, the famous musician, came on stage to give a concert. If you have ever been to a Perlman concert, you know that getting on stage is no small achievement (成就) for him. He suffered from a disease as a child, and so he walks with the help of two walking sticks.

The audience (观众) sat quietly while he makes his way across the stage to his chair and begins his play. But this time, something went wrong. Just as he finished the first few bars, one of the strings (弦) on his violin broke. We thought that he would have to stop the concert. But he didn’t. Instead, he waited a moment, closed his eyes and then signaled the team to begin again.

Of course, anyone knows that it is impossible to play a pleasant work with just three strings. I know that, and you know that, but that night Itzhak Perlman refused to know that.

When he finished, there was a breathtaking silence in the room. And then people rose and cheered. He smiled and said—not proudly, but in a quiet attitude—“You know, sometimes it is the artist’s task to find out how much music you can still make with what you have left.”

This powerful line has stayed in my mind ever since I heard it. And who knows? Perhaps that is the meaning of life—not just for artists but for all of us.

So, perhaps our task in this fast changing, puzzling world in which we live is to make music, at first with all that we have, and then, when that is no longer possible, to make music with what we have left.
