It is sometimes thought that the longing for material goods, the need to buy things, is a relatively modern invention. 1. Trade or shopping is certainly an ancient desire, and existed before our ancestors invented writing, laws, cities or farming, even before they used metal to make tools.
Humans are born to trade. 2. Evidence from hunter-gatherers suggests that the exchange of food and other necessary things comes naturally, as well as the ability to keep a record of the credits involved. And once trade begins, the benefits are hard to resist.
Ancient local coastal people in northern Australia traded fish hooks, along a chain of trading partners, with people living 400 miles inland, who cut and polished local stone to make axes (斧子). 3. Finally, both groups of “producers”, by concentrating on things they could produce and exchanging them for other things they needed, benefited as a result.
Trade in the necessities of life, such as food and simple tools, is not really surprising, considering the link between these basic items and survival. What is surprising, though, is that our taste for unnecessary expensive objects also goes back a long way.
In South Africa, 100,000-year-old decorative dyes (染料) have been found in an area where none were produced. 4. Small round pieces of glass 76,000 years old were also found at the same place. The earliest jewellery known to us were not just random findings — they were grouped together in size and had holes like those used for threading onto a necklace.
Archaeologists argue that trade prepared the way for the complex societies in which we live today. 5. However, their modern equivalents — fast cars and expensive clothes — hold the same attraction for us as “trade goods” did for people 100,000 years ago.
A.And we don’t need shops or money to do it.
B.These are powerful evidence for cash purchase.
C.In fact, its roots go back to the beginning of humanity.
D.However, first trade began from the exchange of objects.
E.Modern-day shoppers may not be impressed by ancient glass pieces.
F.It is thought that these goods were bought at least 30 kilometres away.
G.Every individual along the chain made a profit, even if he produced neither himself.

People have understood that kindness is good for the person who receives help． For example， when we give food to a hungry person， he is blessed． However， scientists have recently begun to study the effect kindness has on the person giving it． What they have found is that doing good is good for the doer． Acts of kindness can improve health， help a person reach goals and even add years to a person's life．
The first study to show the connection between doing good and living a long life was a study on aging． Beginning in 1956， scientists studied a group of married mothers for 30 years． They thought the women with the most children would die first． But the number of children a woman had did not matter． Wealth did not matter． Education did not matter． What did matter was whether they volunteered． Women that volunteered had fewer diseases during their life．
Many other studies have found the same positive effects． Helping other people improves long-term health． The gains are the same for men， women， old people and the young． Those who volunteered had fewer serious diseases than those who did not volunteer． This included diseases such as heart attack， cancer and stroke．
Scientists are researching many possible causes． One possible cause is an increase in antibodies （抗体）， which help fight against disease． One study showed the body produces more antibodies after an act of kindness． This increase in antibodies can last nearly an hour after one act of kindness is finished．
Another one is an increase in a chemical that fights the effects of stress from life． Scientists have found a link between being kind to people and an increase in the chemical oxytocin． Oxytocin is a chemical produced in the brain． It reduces many of the harmful chemicals the body produces under stress．
1.What did the study in Paragraph 2show？ ______
A. Diseases age people fast．
B. Doing good is good for one's health．
C. Women with more kids die earlier．
D. A long marriage leads to a long life．
2.What can we infer about antibodies from Paragraph 4？ ______
A. More antibodies may not be good．
B. They help people reduce pressure．
C. They increase with one's kind acts．
D. The more antibodies， the more oxytocin．
3.How does the author develop the last two paragraphs？ ______
A. By explaining the causes． B. By making comparisons．
C. By introducing a method． D. By describing a chemical．
4.What's the main idea of the text？ ______
A. Everyone needs to be cared for．
B. Happiness is connected with kindness．
C. Try your best to help someone in need．
D. Helping others means helping yourself．
