问题 单项选择题

在建筑结构中,从基础到上部结构全部断开的变形缝是()。

A、伸缩缝

B、沉降缝

C、防震缝

D、温度缝

答案

参考答案:B

解析:

本题考核的是建筑结构变形缝的功能。伸缩缝是为了避免温度变化引起结构伸缩应力,使房屋构件产生裂缝而设置的。基础部分受温度影响小,不用断开设缝,地上建筑部分应设缝。沉降缝是为了避免地基不均匀沉降时,在房屋构件中产生裂缝而设置的。从基础到上部结构,应全部断开设缝。防震缝就是为了避免由这种附加应力和变形引起震害而设置的。基础部分受地震影响位移小,不用断开设缝,地上建筑部分应设缝。

Dear Editor,

I’m now busy in preparing for the Postgraduate (研究生) Entrance Exam. A few days ago, I happened to see some new guidebooks for those who want to take next year’s exam. With too many hopes and without taking it into too much consideration, I bought several that were written by some known for helping candidates (应试者) for master’s degrees.

What made me really angry was the starting discovery that the contents of those books were almost exactly the same as some I had bought before. There were only superficial (外表的) changes in their covers, with more attractive new titles and better designs. The contents were the same.

People say that the publishing industry is in a state of chaos (混乱) these days but I used to be doubtful abut that. I was of the opinion that only people of noble character, prestige (威望), and exceptional talent would produce books for higher education. But these editors are caring little about their readers.

I hope that authors and publishing houses will be more responsible for their readers. Don’t destroy the image that you have with your readers.
