[单项选择]Passage Four
We all know that people sometimes change their behavior when someone is looking their way. Now, a new study reported online on April 2nd in Current Biology shows that jackdaws —birds related to crows with eyes that appear similar to human eyes — can do the same.
“Jackdaws seem to recognize the eye’s role in visual perception, or at the very least they are extremely sensitive to the way that human eyes are oriented,” said Auguste von Bayern, formerly of the University of Cambridge and now at the University of Oxford.
When presented with a preferred food, hand-raised jackdaws took significantly longer to retrieve the reward when a person was directing his eyes towards the food than when he was looking away, according to the research team led by Nathan Emery of the University of Cambridge. The birds hesitated only when the person in question was unfamiliar and thus potentially threatening.

[单项选择] Passage 4
All of us communicate with one another
non-verbally, as well as with words. Most of the time we’re not aware that we’re
doing it. We gesture with eyebrows or a hand, meet someone else’s eyes and look
away, shift positions in a chair. These actions we assume are random and
incidental. But researchers have discovered in recent years that there is a sys-
tem to them almost as consistent and comprehensible as language.
Every culture has its own body language, and children absorb its nuances
along with spoken language. A Frenchman talks and moves in French. The way an
Englishman crosses his legs is nothing like the way a male American does it. In
talking, Americans are apt to end a statement with a droop of the head or hand,
a lowering of the eyelids. They wind up a question with a lift of the hand, a
lift of the chin or a widening of
A. random and incidental
B. consistent and comprehensible
