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

A few years ago I had an "aha!" moment regarding handwriting.

I had in my hand a sheet of paper with handwritten instructions on it for some sort of editorial task. It occurred at first that I did not recognize the handwriting, and then I realized whose it must be. I finally became aware of the fact that I had been working with this colleague for at least a year, maybe two, and yet I did not recognize her handwriting at that point.

It was a very important event in the computerization of life—a sign that the informal. Friendly communication of people working together in an office had changed from notes in pen to instant messages and emails. There was a time when our workdays were filled with little letters, and we recognized one another’s handwriting the way we knew voices or faces.

As a child visiting my father’s office, I was pleased to recognize, in little notes on the desks of his staff, the same handwriting I would see at home in the notes he would leave on the fridge—except that those notes were signed "dad" instead of "RFW".

All this has been on my mind because of the talk about The Rise and Fall of Handwriting, a book by Florey. Sire shows in her book a deep concern about the fall of handwriting and the failure of schools to teach children to write well, but many others argue that people in a digital age can’t be expected to learn to hold a pen.

I don’t buy it. I don’t want to see anyone cut off from the expressive, personal associations that a pen still promotes better than a digital keyboard does. For many a biographer, part of really getting to know their subjects is learning to read their handwriting.

What some people advocate is teaching one of the many attractive handwritings based on the handwriting of 16th century Italy. That may sound impossibly grand—as if they want kids to learn to draw by copying classical paintings. However, they have worked in many school systems.

People working together in an office used to().

A．talk more about handwriting

B．take more notes on workdays

C．know better one another’s handwriting

D．communicate better with one another
