题目内容

【题目】2010年元旦过后,美国科幻大片《阿凡达》在我国上映。影片讲述人类试图从极遥远的潘多拉星球(距离太阳大约4.4亿光年)开采矿产以解决地球的能源危机而与纳美人(潘多拉星球上的土著人类)发生一系列矛盾冲突。回答下列问题。

【1】假如影片中潘多拉星球在宇宙中是存在的,那么它不可能属于

A.总星系 B.银河系 C.河外星系 D.太阳系

【2】影片中地球人在潘多拉星球行动时需要带氧气罩,证明其大气不适合人类呼吸,适合生物呼吸的大气是地球上存在生命的重要条件之一,下列叙述与地球大气有密切关系的是

A.地球的质量与体积适中 B.地球的昼夜更替周期适中

C.地球与太阳的距离比较适中 D.地球自转周期适中

【答案】

【1】D

【2】A

【解析】

试题分析:

【1】根据天体系统的层次关系:最低一级的天体系统是地月系,较地月系高一级的天体系统是太阳系,比太阳系再高一级的天体系统为银河系和河外星系,最高一级的天体系统为总星系.潘多拉星球距离太阳约4.4亿光年,说明他不属于太阳系,银河系系主体部分的直径约为8万光年,说明它可能在银河系的范围内,它可能属于河外星系,总星系是可见宇宙,该星球属于总星系。故选D。

【2】地球的质量体积适中使得地球有合适的大气厚度和大气成分,A对。地球的昼夜更替周期适中使地球的昼夜温差适中,B错。地球与太阳的距离比较适中,使得地球有适宜生物生存的温度范围,C错。地球自转周期适中,与大气产生无关,D错。故选A。

【题目】阅读下面短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

My 17-year-old daughter went off to college and having her away from home brought back memories of watching Peter Pan when she was little. In the classic TV production, one scene in particular impressed me: when Mrs. Darling puts her children into bed. As she turns off the last of the night light, she takes one last look at the bedroom and says, “Dear night lights, protect my sleeping children.” As a mother, I know how much she loves her children.

It has been several weeks since we took our daughter to college and she seems to be adjusting well after a short period of homesickness. For us, though, it’s another story. Like most parents, I love checking in on my children at night. But now she’s gone, and I find night times the hardest. I miss her most at night.

In my neighborhood, most of the parents whose kids are off to college are dealing with similar melancholy. My husband is filled with anxiety. We complained that many of us were too busy to truly enjoy being with our children while we had them.

For us moms, seeing Toy Story 3 only made the sadness worse as we watched the character Andy, who is the same age as our kids, say goodbye to his childhood as he prepares to leave for college. And it’s not just “first-time” parents like me. Two moms who have kids already well into college said the separation didn’t get any easier.

As I keep my cell phone close to me in bed and text my daughter goodnight and sweet dreams every night, I like to think at messages serve as a night light that keeps her safe.
