阅读《中国石拱桥》中的节选文字,完成后面小题。

赵州桥非常雄伟,全长50.82米,两端宽9.6米,中部略窄,宽9米。桥的设计完全合乎科学原理,施工技术更是巧妙绝伦。唐朝的张嘉贞说它“制造奇特,人不知其所以为”。这个桥的特点是:(一)全桥只有一个大拱,长达37.4米,在当时可算是世界上最长的石拱。桥洞不是普通半圆形,而是像一张弓,因而大拱上面的道路没有陡坡,便于车马上下。(二)大拱的两肩上,各有两个小拱。这个创造性的设计,不但节约了石料,减轻了桥身的重量,而且在河水暴涨的时候,还可以增加桥洞的过水量,减轻洪水对桥身的冲击。同时,拱上加拱,桥身也更美观。(三)大拱由28道拱圈拼成,就像这么多同样形状的弓合拢在一起,做成一个弧形的桥洞。每道拱圈都能独立支撑上面的重量,一道坏了,其他各道不致受到影响。(四)全桥结构匀称,和四周景色配合得十分和谐;就连桥上的石栏石板也雕刻得古朴美观。唐朝的张族鸟说,远望这座桥就像“初月出云,长虹饮涧。”赵州桥高度的技术水平和不朽的艺术价值,充分显示了我国劳动人民的智慧和力量。桥的主要设计者李春就是一位杰出的工匠,在桥头的碑文里刻着他的名字。

小题1:下面解说不准确的一项是:(   )

A.这段文字要说明的是赵州桥的外形和设计施工特点。

B.从选段可以看出赵州桥体现了中国石拱桥结构坚固、形式优美的特点。

C.引用张的赞语“出月初云,长虹饮涧”是为了说明赵州桥构造奇特。

D.文中加点的“在当时可算”不能删去,“当时”是从时间上限定,“可算”是从程度上限定,经过限定的结论才更符合实际情况。小题2:赵州桥比其他石拱桥结构坚固的主要原因是:(   )

A.非常雄伟,全场50.82米,两端宽9.6米,中部略窄,宽9米。

B.全桥只有一个大拱,长达37.4米,像一张弓,大拱上面的道路没有陡坡。

C.打工的两肩上,各有两个小工,这样就减轻了桥身的重量和洪水对桥身的冲击。大拱的28道拱圈,每道拱圈都能独立支撑上面的重量。

D.全桥结构匀称,和四周的景色配合得十分和谐。小题3:选段运用的主要说明方法是:(   )

A.列数据举例子 作比较

Mom was right! If you say thank you, for even the smallest gift or slightest show of kindness, you’ll feel happy.

Gratitude, says Robert A. Emmons, a professor of psychology at the University of California, is an important element of happiness. In his recent book, Thanks!, Emmons uses the first major study on gratitude to prove mom’s point.

As one of the leading scholars of the positive psychology movement, he admits gratitude may be difficult to express. He advises you to begin by admitting that life is good and full of events and elements that make daily existence a wonder. Second, recognize that the source of life’s goodness is more than just you. That source may be your mom, a friend, partner, child, colleague at work or play.

Gratitude is always other-directed, notes Emmons. You can be pleased or angry with yourself and feel guilty about doing something wrong, but you can never be grateful to or for yourself.

Expressing gratitude shouldn’t be a reaction; it should be a state of mind. To feel grateful when life is a breeze and you have more than you need is easy. To feel grateful in time of crisis—anger, hatred and bitterness—is easier. Also, too many people are aware of life’s blessings only after these are lost.

It’s crisis and chaos—danger, disease, disability and death—that bring many individuals to realize just how dependent they are on others. Yet it’s the way each of us begins life and ends it. It’s too bad that so many people waste those decades in between laboring under the illusion(幻觉) they are self-sufficient, says Emmons.

The abundance of voices expressing gratitude from his studies of individuals with chronic health problems is many. But Emmons goes beyond his “groundbreaking” science to make his case for gratitude by including the inspirational writings of philosophers, novelists and saints, as well as the beliefs of various religious and their respective scripture(经文). Taken together, these observations are summed up quite nicely by famous humanist Albert Schweitzer, who said the secret of life is “giving thanks for everything”.

To enable and embrace gratitude, Emmons encourages the readers of Thanks! to keep a gratitude diary. He even provides easy-to-follow directions on how to practise and develop gratitude.

I’m not a reader or advocate of self-help books, but I am thankful for the reference I found in a newspaper article to the research Emmons was conducting on gratitude involving organ donors and recipients. The chance discovery led me to this book.

Mom implied that kindness seems to find its way back to the giver because life really is all about giving, receiving and repaying. So I’ll pay attention to her professional advice and say: Thank you, professor Emmons.
