Psychology, philosophy, and anthropology are all concerned with the study of meaning.()

Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the same reasoned, orderly, systematic, and dispassioned(原文如此) manner that natural scientists use for the study of natural phenomena.

Research on animal intelligence always makes me wonder just how smart humans are. 1 the fruit-fly experiments described in Carl Zimmer’s piece in the Science Times on Tuesday. Fruit flies who were taught to be smarter than the average fruit fly 2 to live shorter lives. This suggests that 3 bulbs burn longer, that there is an 4 in not being too terrifically bright.

Intelligence, it 5 out, is a high-priced option. It takes more upkeep, burns more fuel and is slow 6 the starting line because it depends on learning — a gradual 7 — instead of instinct. Plenty of other species are able to learn, and one of the things they’ve apparently learned is when to 8 .

Is there an adaptive value to 9 intelligence? That’s the question behind this new research. I like it. Instead of casting a wistful glance 10 at all the species we’ve left in the dust I.Q.-wise, it implicitly asks what the real 11 of our own intelligence might be. This is 12 the mind of every animal I’ve ever met.

Research on animal intelligence also makes me wonder what experiments animals would 13 on humans if they had the chance. Every cat with an owner, 14 , is running a small-scale study in operant conditioning. we believe that 15 animals ran the labs, they would test us to 16 the limits of our patience, our faithfulness, our memory for terrain. They would try to decide what intelligence in humans is really 17 , not merely how much of it there is. 18 , they would hope to study a 19 question: Are humans actually aware of the world they live in? 20 the results are inconclusive.

Here&39;s a familiar story. You&39;re sitting at the dinner table with a furry, four-legged friend scratching at your feet. When you look down, those cute eyes are almost impossible to resist.

What is it about a dog&39;s gaze that makes it so charming? A new study by Japanese scientist Miho Nagasawa seems to have found the answer, and it has to do with something called the cuddle(爱抚)chemical.

The cuddle chemical has another, more scientific name: oxytocin. Oxytocin is a substance in the blood that encourages bonding. Levels of oxytocin increase, for example, when a mother feeds her newborn baby. According to Nagasawa&39;s study, the same is true when we look deeply into the eyes of a dog.

The results of this study can tell us a lot about the history of the bond between humans and dogs. It all started somewhere tens of thousands of years ago. Scientists believe that wolves used to follow humans who were hunting large animals. The wolves would eat the food left behind by the humans.

Humans realized that they could use the wolves to help with the hunt, and eventually both species began to work together toward survival.

Over time, the wolves that interacted with the humans began to change. They became more loyal to their human partners. The wolves and humans started to depend on each other and bond with each other. These changes are what caused some of the wolves to turn into what we now know as dogs, a new specie^ evolved to better survive in their environment.

This process depended a great deal on the bond humans formed with them. And according to Nagasawa&39;s study, this bond was formed with the help of oxytocin, the cuddle chemical.

11. What do we know about oxytocin?

A.It regulates blood flow

B.It promotes bonding

C.It is in the human gene

D.It is good for health

When we look deeply into a dog's eyes, the levels of our oxytocin ____.A.reduce over time

B.go either up or down

C.are on the rise

D.remain unchanged

At the beginning wolves followed humans to ____.A.eat the food left by humans

B.guard against large animals

C.take humans for food

D.hunt large animals together

Over time some wolves turned into dogs ____.A.due to their loyalty

B.due to the changing environment

C.for better survival

D.for better cooperation

What does Nagasawa9s study aim to do?A.Explore the role of human-wolf partnership

B.Show the characteristics of the cuddle chemical

C.Explain the bond between humans and dogs

D.Understand the evolution of species
