单项选择题
岩质边坡的圆弧滑动破坏一般发生在( )。
A．不均匀岩体
B．薄层脆性岩体
C．厚层泥质岩体
D．多层异性岩体
答案
参考答案：C
解析： 厚层泥质岩体的抗剪切强度低，在岩体的滑坡剪切力作用下，坡体沿应力最弱面剪切滑动破坏，产生滑坡。转动滑动一般发生在土质边坡中，但在风化岩、厚层页岩或节理切割非常破碎的岩质边坡中也有发生。

Have you ever received a gift that was so clearly not your taste? Worse, have you ever given a present and watched your friend look as though she had opened the wrong box? 小题1:__________? And what do your choices tell about your personal qualities（品质）? 小题2:__________. It calls for empathy—the ability to put yourself into someone else’s head and heart. We’re all able to do this; in fact, we’re born with a kind of natural empathy. 小题3:__________. When it isn’t, we’re not able to understand other people’s feelings sharply. Think back to the presents you’ve given over the past year, the time and effort you put into your selection, how much you spent, your thoughts while you were shopping, and your feelings when the receiver opened the package. Keep in mind that what you choose shows your inner world. We live in a society where exchanging presents is an important part of communication. Passing over the tradition won’t make it go away. 小题4:__________, tell your friends ahead of time.
