Humans are naturally drawn to other life forms and the world

A new study shows that humans had the ability to make
fire nearly 790,000 years ago,a skill that helped them migrate from Africa
to Europe.
By analysing flints at an archaeological site on the bank of the river
Jordan,researchers at Israel's Hebrew University discovered that early
civilizations had learned to light fires,a turning point that allowed them
to venture into unknown lands.
A previous study of the site published in 2004 showed that man had been able
to control fire -- for example transferring it by means of burning branches
-- in that early time period.But researchers now say that ancient man
could actually start fire,rather than relying on natural phenomena such as
lightning.
That independence helped promoted migration northward,they say.
The new study,published in a recent edition of Quaternary Science Reviews,
mapped 12 archaeological layers at Gesher Benot Yaaqov in northern Israel.
"The new data shows there was a continued,controlled use of fire through
many civilizations and that they were not dependent on natural fires,"
archaeologist Nira Alperson-Afil said on Sunday.
While they did not find remnants of ancient matches or lighters,Alperson-
Afil said the patterns of burnt flint found in the same place throughout 12
civilizations was evidence of fire-making ability,though the methods used
were unclear.
And because the site is located in the Jordan valley -- a key route between
Africa and Europe -- it provides evidence of the human migration,she said.
"Once they mastered fire to protect themselves from predators and provide
warmth and light,they were secure enough to move into and populate
unfamiliar territory," Alperson-Afil said.

We sometimes think humans are uniquely vulnerable to anxiety, but stress seems to affect the immune defenses of lower animals too. In one experiment, for example, behavioral immunologist (免疫学家) Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could mot. The rats in the two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstrated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.
　　Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don’t develop sleep disturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can control. Such findings reinforce psychologists’ suspicions that the experience or perception of helplessness is one of the most harmful factors in depression.
　　One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975 psychologist Robert Ader at the University of Rochester School of Medicine conditioned (使形成条件反射) mice to avoid saccharin (糖精) by simultaneously feeding them the sweetener and injecting them with a drug that while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader reexposed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlier conditioning died. He could onlyspeculate that he had so successfully conditioned the rats that saccharin alone now served to weaken their immune systems enough to kill them.

Thirty-five years ago,on July 20,1969,humans first set foot on another world.U.S.Apollo 11 astronaut Neil Armstrong descended from a landing craft named "Eagle" to become the first person to step on the moon,a momentous event he eloquently consecrated.
"That's one small step for man,one giant leap for mankind," he said.
For many,it was the high point of a U.S.space program that was fueled by political adrenaline to compete with the Soviet Union.

请分析一下Studies of both animals and humans have shown that .,
Studies of both animals and humans have shown that sex hormones somehow affect the stress response,causing females under stress to produce more of the trigger chemicals than do males under the same conditions.

Ever since humans have lived on the earth,they have made use of various forms of communication．Generally,this expression of thoughts and feelings has been in the form of oral speech．When there is a language barrier(障碍),communication is completed through sign language in which motions stand for letters,words,and ideas．Tourists and the people unable to hear or speak have had to turn to this form of expression．Many of these symbols of whole words are very lively and exact and can be used internationally; spelling,however,cannot．
Body language sends ideas or thoughts by certain actions,either meaningfully or not．A wink(眨眼) can be a way of showing that the party is only joking．A nod means agreement,while shaking the head indicates disagreement．
Other forms of nonlinguistic(非语言的) language can be found in Braille (a system of raised dots read with the fingertips),signal flags,Morse code,and smoke signals．Road maps and picture signs also guide and warn people．While language is the most common form of communication,other systems and techniques also express human thoughts and feelings．

Thinking ·Some scientists claim that we humans are the only living things that are conscious(有意识的)—we alone are aware that we are thinking. ·No one knows how consciousness works—it is one of science’s last great mysteries. ·All your thoughts take place in the cerebrum(大脑皮质),which is at the top of your brain,and different kinds of thought are linked to different areas,called association areas. ·Each half of the cerebrum has four rounded ends called lobes(脑叶)—two at the front(frontal and temporal lobes)and two at the back(occipital and parietal lobes). ·The frontal lobe is linked to your personality and it is where you have your bright ideas. ·The temporal lobe is where you hear and understand what people say to you. ·The occipital lobe is where you work out what your eyes see. ·The parietal lobe is where you record touch,heat and cold,and pain. ·The left half of the brain controls the right side of the body.The right half controls the left side. ·One half of the brain is always dominant(in charge).Usually,the left brain is dominant,which is why 90% of people are right-handed. 小题1:Which part of your cerebrum is most active when you are making a telephone call? A．The frontal lobe. B．The temporal lobe. C．The occipital lobe. D．The parietal lobe. 小题2:Which of the following statements is true? A．One’s personality has something to do with the frontal lobe. B．Bright ideas come from the parietal lobe. C．The occipital and temperal lobes are at the back of the cerebrum. D．The occipital lobe is in charge of sound. 小题3:From the passage,we know the reason why around 10% of people are left-handed is that_______. A．their frontal lobe is usually dominant B．their temporal lobe is usually dominant C．their right brain is usually dominant D．their left brain is usually dominant

There are some things humans can go without. We can lose a kidney or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can get by without stomachs. One such fish is the stout longtom. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost. The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. It teeth are not good at cutting fish into pieces, so it swallows fish whole. Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish. Day’s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin that can break down proteins without acid — although the approach is less efficient than using a stomach. Because it’s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein. Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is “a fairly expensive organ to run”. This perhaps explains why some animals have got rid of theirs. 小题1:What does the underlined phrase “get by” mean? A．Recover. B．Fight. C．Hunt. D．Live. 小题2:Ryan Day ran the chemical tests in order to find out how the longtom ______. A．catches smaller fish in the water B．digests the smaller fish in its body C．can jump so high to escape its enemies D．uses acid to break down the protein 小题3:What plays a key role in the longtom’s digestion process? A．Trypsin. B．Acid C．The stomach. D．Protein in its body. 小题4:Ryan Day’s results show that ______. A．the longtom can make acid easily B．the longtom often waste energy C．the longtom’s high-protein food helps its unique way of consuming food. D．meat –eating fish have higher levels of trypsin in their bodies than plant-eating fish

英语如何划分谓语
我今天在看一本参考书的时候他有个疑难句成分划分,句子如下
Even though humans have been upright for millions of years,our feet and back continue to struggle with bipedal posture and cannot easily withstand repeated strain imposed by oversize limbs.
我的问题是,书中把continue to struggle with划分为谓语,我想这里to struggle 不定式应该做宾语吧?还是怎么回事,我看书中分的好多谓语我都看的不大明白.
我不是很懂啊，那谓语里怎么能有非谓语动词呢，to struggle是不定式吗？那不定式书上说叫非谓语动词啊，怎么这儿成了谓语了
看来不能教条主义啊
那么看这个句子呢：President Bush campaigned to move Social Security to a saving-account model谓语是什么呢？书上说只有campaign是谓语那这儿怎么又没有to move了呢，有点儿迷茫
