环刀法测定土层密度时，若环刀取在碾压层的底部，则测试数值与灌砂法结果（）。A.相等

When I was a kid, I used to spend hours listening to Adam Carolla and Dr. Drew Pinsky on their Sunday night radio show Loveline. I listened so often that I began to use one of their well-known phrases—“good times”—in my daily conversations. Scientists have a name for this phenomenon: behavioral mimicry.

You’ve probably experienced this before: after spending enough time with another person, you might start to pick up on his or her behavior or speech habits. You might even start to develop your friend’s habits without realizing it. There is a large body of literature concerning this sort of phenomenon, and it regularly happens for everything from body postures to accents to drink patterns. For example, one study found that young adults were more likely to drink their drink directly after their same-sex drinking partners, than for the two individuals to drink at their own paces.

And the effect isn’t limited to real-life face-to-face activities. Another study found that the same you-drink-then-I-drink pattern held even when watching a movie! In other words, people were more likely to take a drink of their drinks in a theater after watching the actors on the screen enjoy a drink. At least I don’t feel so strange anymore, having picked up on Adam Carolla’s “good times”.

New research published today in the journal PLOS ONE indicates that the same sort of behavioral mimicry is responsible for social eating, at least among university-age women of normal weight. That’s right: the young women were more likely to adjust their eating according to the eating pace of their same-sex dining companion.

As with most experiments, these results raise a whole new set of questions. Still, the finding that behavioral mimicry may at least partly account for eating behavior is important, and has real effects on health. The researchers note that “as long as people don’t fully recognize such important influences on intake, it will be difficult to make healthy food choices and keep a healthy diet, especially when people are exposed to the eating behavior of others”.

阅读下面短文，回答下 * * 道题。
汉字究竟起源于何时呢我认为，这可以以西安半坡村遗址距今的年代为指标。半坡遗址的年代，距今有6000年左右。我认为，这也就是汉字发展的历史。
半坡遗址是新石器时代仰韶文化的典型，以红质黑纹的彩陶为其特征。其后的龙山文化，则以薄质坚硬的黑陶为其特征。值得注意的是：半坡彩陶上每每有一些类似文字的简单刻画，和器物上的花纹判然不同。黑陶上也有这种刻画、但为数不多。该画的意义至今虽尚未阐明，但无疑是具有文字性质的符号，如花押或者族徽之类。我国后来的器物上，无论是陶器、铜器或者其他成品，有“物勒工名”的传统，特别是殷代的青铜上有一些表示族徽的刻画文字，和这些符号极为相类似。由后以例前，也就如由黄河下游以溯源于星宿海，彩陶上的那些刻画符号，可以肯定地说就是中国文字的起源，或者中国原始文字的孑遗。
同样值得注意的，是彩陶上的花纹。结构虽然简单，而笔触颇为精巧，具有引人的魅力。其中有些绘画，如人形、人面形、人着长衫形、鱼形、首形、鸟形、草木形、轮形(或以为太阳)等等，画得颇为得心应手，看来显然在使用柔软形的笔了。有人以为这些绘画是当时的象形文字，其说不可靠。当时是应该有象形文字的，但这些图形，就其部位而言，确是花纹，而不是文字。
在陶器上既有类似文字的刻画，又有使用着颜料和柔软形的笔所绘画的花纹，不可能否认在别的质地上，如竹木之类，已经在用笔来书写初步的文字：只是这种质地是容易毁灭的，在今天很难有实物保留下来。如果在某种情况之下，幸运的还有万一的保留，那就有待于考古工作的进一步发掘和幸运地发现了。
总之，在我看来，彩陶和黑陶上的刻画符号应该是汉字的原始阶段。创造它们的是劳动人民，形式是草率急就的。

下列几种说法中与原文意思不相符合的一项是( )。

A．仰韶文化的彩陶上和龙山文化的黑陶上的刻画符号都是原始文字。

B．半坡彩陶上的刻画的意义已能解释，而龙山黑陶上的刻画的意义尚未阐明。

C．新石器时代仰韶文化时期已有了用笔书写的初步文字，只是难以保留到今天。

D．半坡彩陶上的刻画符号合乎古代“物勒工名”的传统，因此它们是有意义的。
