Are we getting more stupid? According to Gerald Crabtree, a scientist at Stanford University in the US, we are. You may not want to hear this, but Crabtree believes that human intelligence reached its peak more than 2,000 years ago and ever since then has been going downhill. “If an average Greek from 1,000 BC were transported to modern times, he or she would be one of the brightest among us,” Crabtree told The Guardian.
At the heart of Crabtree’s thinking is a simple idea. In the past, intelligence was critical for survival when our ancestors had to avoid dangerous animals and hunt for food. The difference of being smart or stupid is often life or death. However, after the spread of agriculture, when our ancestors began to live in dense ( 稠密的)farming communities, the need to keep their intelligence in peak condition gradually reduced. This is not hard to understand. Most of the time,pressure is what keeps us going – you need the pressure from your teachers to finish your homework; the pressure of looking pretty prompts(促使) you to lose weight when summer comes. And the same is also true of our intelligence – if we think less, we become less smart.
These mutations(變) are harmful to our intelligence and they were all developed in the past 3,000 years. The other evidence that Crabtree holds is in our genes. He found that among the 2,000 to 5,000 genes that we have that determine human intelligence , there are two or more mutations in each of us. However, Crabtree’s theory has been criticized by some who say that early humans may have better hunting and surviving abilities, but people today have developed a more diverse intelligence. For example, spearing a tiger doesn’t necessarily require more brainpower than playing chess or writing a poem. Moreover, the power of modern education means a lot more people have the opportunity to learn nowadays. “You wouldn’t get Stephen Hawking 2,000 years ago. He just wouldn’t exist,” Thomas Hills of the University of Warwick, UK, told Live Science. “But now we have people of his intellectual capacity doing things and making insights(洞察力) that we would never have achieved in our environment of evolutionary adaptation.”
1.What is Crabtree’s recent finding according to the article?
A. The Greeks from 1,000 BC could have been the smartest in human history.
B. Our ancient ancestors had no better surviving abilities than we do nowadays.
C. Humans have been getting steadily more intelligent since the invention of farming.
D. Mutations in genes that decide human intelligence have affected the development of intelligence.
2.According to Crabtree, ancient humans _______.
A. had many more genes that determine human intelligence
B. were forced to be smart due to natural selection pressures
C. relied more on group intelligence than individual intelligence
D. developed a diverse intelligence to adapt to the hard realities
3.Some argue that Crabtree’s theory is false because they think _______.
A. people today are under much more pressure than early humans
B. it’s ridiculous to compare a hunter’s and a poet’s intelligence
C. modern education is far more advanced than ancient education
D. human intelligence nowadays is different from that of the distant past
4.What is Thomas Hills’ attitude toward Crabtree’s theory?
A. Supportive B. Unfavorable
C. Worried D. Confused

Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保護) of the African elephant faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That’s why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.
Years ago, over hunting and the ivory trade were the biggest threats to elephants survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.
The 21st century brings a different challenge to elephant conservation —land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (沖突) between local farmers and these big animals.
Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.
AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.
The AWF is helping elephants by protecting their habitats. And they also work with local farmers to improve their life in order to encourage them to protect rather than destroy elephants.
1.The first paragraph of the text is mainly to tell readers _____.
A. African elephants are endangered now
B. there remains a lot to do to protect African elephants
C. African elephants are popular animals
D. the number of African elephants has increased over the years
2.What is the biggest difficulty in protecting African elephants now?
A. They are still being killed.
B. Their habitats are being destroyed.
C. They don’t have enough food.
D. They can’t live in peace with farmers.
3.To protect elephants, the AWF does all the following EXCEPT _____.
A. keeping elephants
B. protecting elephants’ habitats
C. doing research on elephants
D. helping farmers improve their life
4.What is the best title for the text?
A. African elephants conservation
B. Living with African elephants
C. African elephants’ situation
D. African elephants being endangered

Dear Editor,
I used to be a physician in the children’s department of a hospital. From time to time I treated children who had poisoned by medicine with older family members. The children didn’t know the medicine was danger; they just knew it tasted sweet. Children easily open the bottle what we now use in China.
Some days before I talked about medicines with an American. He showed me a sort of plastic bottle. The design was quite simple and I’m sure our Chinese factories could produce these bottles. The top of the bottle can be opened by pressing down on them while turning, which is difficult for most young children to do so, though grown-up can open these bottles very easily.
I’m certainly that the expense of making such tops would be very small. As a doctor, I’d love to see this doing. And most parents would be grateful.
Sincerely yours
Li Hua

Two recent studies have found that punishment is not the best way to influence behavior.
One showed that adults are much more cooperative if they work in a system based on rewards. Researchers at Harvard University in the United States and the Stockholm School of Economics in Sweden did the study.
They had about two hundred college students play a version of the game known as the Prisoner's Dilemma. The game is based on the tension (緊張氣氛) between the interests of an individual and a group. The students played in groups of four. Each player could win points for the group, so they would all gain equally. But each player could also reward or punish each of the other three players, at a cost to the punisher.
Harvard researcher David Rand says the most successful behavior proved to be cooperation. The groups that rewarded it the most earned about twice as much in the game as the groups that rewarded it the least. And the more a group punished itself, the lower its earnings were. The group with the most punishment earned twenty?five percent less than the group with the least punishment. The study appeared last month in the journal Science.
The other study involved children. It was presented last month in California at a conference on violence and abuse. Researchers used intelligence tests given to two groups. More
than eight hundred children aged two to four the first time they were tested. More than seven hundred children aged five to nine.
The two groups were retested four years later, and the study compared the results with the first test. Both groups contained children whose parents used physical punishment and children whose parents did not. The study says the IQs — or intelligence quotients — of the younger children who were not spanked were five points higher than those who were. In the older group, the difference was almost three points.
Murray Strauss from the University of New Hampshire worked with Mallie Paschall from the Pacific Institute for Research and Evaluation. Professor Strauss has written extensively about physical punishment of children. He says the more they are spanked, the slower their mental development. He also looked at average IQs in other nations and found them lower where spanking was more common.
1.Which could be the best title of the passage?
A.Punishment
B.The Best Way to Influence Behavior
C.Punishment or Reward: Which Works Better on Behavior?
D.Two Recent Studies
2.The underlined word “spanked” probably means “______”.
A.won B.punished
C.tested D.praised
3.According to the passage, the researchers may agree the best way to influence behavior is ________.
A.rewarding good behavior
B.correcting bad behavior
C.punishing badly?behaved children
D.praising well?behaved children
4.The author develops the passage ________.
A.in order of time
B.in order of importance
C.by describing his experiences
D.by using quotations (引證) and statistics
