问题 单项选择题

(四) 阅读下面短文,回答下 * * 道题。
亚马逊丛林中的雄性蓝蝶带有彩虹般的蓝色光辉,半公里外就能看到。其光辉如此强烈,有的竟能反射70%的蓝色光线,远远超过蓝色涂料的反射率。蓝蝶耀眼的光辉,原是一种警号,使别的雄性蓝蝶在远处就能知所趋避。蓝光越强,示警作用越显著。物竞天择,适者生存,亿万年的自然选择,使亚马逊蓝蝶翅膀有了如此奇妙的性能。
这种性能,早在100多年前就被人发现,但其奥秘直到最近才被揭开。原来蓝蝶翅膀上覆盖着许多微小鳞片(就是触摸蝴蝶翅膀时会沾手的粉),其表面有许多平行的脊状突起物。观察脊的截面,会发现其中包含着许多平行排列的羽状物。“羽毛”的主干两边生出若干分支,分支的长度沿主干从根到梢逐渐变短,其结构类似于人造的多层介质反射镜。人造多层介质反射镜的反射光有很强的方向性:对接近垂直入射的单色光线反射率极高,但对斜入射光线的反射率很低。令科学家们大吃一惊的是:蓝蝶翅膀的反光却是广角的,可以在很大范围内看到。这种奇妙性能缘于那些羽状物的分支并非完全位于同一平面内,而是各具略为不同的倾斜角,使反光的视角大为增加。蓝蝶的翅膀还具有颜色选择性,其羽状物的尺寸恰好能增强蓝光的反射,而且其分支越多,反光就越强。一种仅有6~8个分支的蓝蝶翅膀,仍比蓝色涂料的反光率高出一倍以上。蓝蝶翅膀的反射光颜色随不同的视角略有变化,从蓝色到紫色,一直延伸到人眼看不见但蓝蝶能看见的紫外线。
目前人们正在研究蓝蝶的反光机理,想仿造应用。比如改善公路上的路标,改善电脑的液晶显示器。军事部门感兴趣的是仿蓝蝶翅膀的反光结构,将之用于可随环境变换色彩的新型迷彩伪装;服装公司则设想,仿蓝蝶翅膀做出的具有特殊反光性能的衣料,将使时装展示台上更加异彩纷呈。最重要的应用当然是有价证券的防伪,因为再先进的复印机也无法印造出具有精细立体结构的蓝蝶翅膀来。
纽约州立大学的一位昆虫学家说:“蓝蝶做到了工程师们试着做却未能成功的事。”的确,正在研究中的人造模仿物,在光学性能上仍无法与蓝蝶的翅膀相比。

根据文意,下列推断不合理的一项是( )。

A.从飞越亚马逊丛林的小飞机上,有可能看到蓝蝶发出的蓝色闪光

B.人造的多层介质反射镜,其反射光不够强烈,是因角度所限

C.亚马逊丛林中美丽的蓝蝶,可能成为制造假钞罪犯的“克星”

D.有关蝴蝶的传说,可能因蓝蝶反光的奥秘被揭开而更添浪漫色彩

答案

参考答案:B

解析: 本题考查的重点是“依据作品内容进行的合理推断”。和反射的角度,是两个问题。文中并没有谈过它们之间存在因果关系。更何况“人造多层反射镜”反光不强烈的说法,与文中的叙述存在明显的矛盾。所以根据文意来看,B项的推断显然不合理。

It’s a typical Snoopy card: cheerful message, bright colors, though a little yellow and faded now. Though I’ve received fancier, more expensive cards over the years, this is the only one I’ve saved. One summer, it spoke volumes to me.
I received it during the first June I faced as a widow to raise two teenage daughters alone. In all the emotional confusion of this sudden single parent- hood, I was overwhelmed with, of all things, the simplest housework: leaky taps, oil’ changes, even barbecues (烧烤). Those had always been my husband’s jobs. I was embarrassed every time I hit my thumb with a hammer or couldn’t get the lawnmower (割草机) started. My uncertain at- tempts only fueled the fear inside me: How could I be both a father and mother to my girls Clearly, I lacked the tools and skills.
On this particular morning, my girls pushed me into the living room to see something. (I prayed it wasn’t another repair job). The "something" turned out to be an envelope and several wrapped bundles on the carpet. My puzzlement must have been plain as I gazed from the colorful packages to my daughters’ bright faces.
"Go ahead! Open them!" they urged. As I unwrapped the packages, I discovered a small barbecue grill (烧烤架) and all the necessary objects in- eluding a green kitchen glove with a frog pattern on it.
"But why" I asked.
"Happy Father’s Day!" they shouted together.
"Moms don’t get presents on Father’s Day," I protested.
"You forgot to open the card," Jane reminded. I pulled it from the envelope. There sat Snoopy, on top of his dog house, merrily wishing me a Happy Father’s Day. "Because," the girls said, "you’ve been a father and mother to us. Why shouldn’t you be remembered on Father’s Day"
As I fought back tears, I realized they were right. I wanted to be a "professional" dad, who had the latest tools and knew all the tricks of the trade. The girls only wanted a parent they could count on to be there, day after day, performing repeatedly the maintenance tasks of basic care and love.
The girls are grown now, and they still send me Father’s Day cards, but none of those cards means as much to me as that first one. Its simple message told me being a great parent didn’t require any special tools at all--just a willing worker.

By "it spoke volumes to me" (Para. 1), the mother in the story means the card ______.

A. conveyed significant meanings to her
B. aroused great sorrow in her
C. brought her pleasant feelings
D. made her feel, important
