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 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(变异) 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.”
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.

According to Crabtree, ancient humans _______.

A.had much 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

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

What is Thomas Hills’ attitude toward Crabtree’s theory?

A.Supportive B.Unfavorable C.Worried D.Confused

Kang Heng, 16, hasn’t been sleeping well in a tent the past couple of nights. Closing his eyes only brings repeated terror from all that happened and, worse still, all that could have happened at around 2:30 pm last Monday.
The student in Dongcheng High School in Mianyang, Sichuan Province was on his way to class after an afternoon nap(小睡) when the big earthquake hit the area.
“It’s a complete shock! As soon as I heard someone screaming ‘Earthquake!’ I saw our classroom building being torn apart just in front of my eyes. The next second I saw a student jumping out of the window from the second floor,”Tang recalled.
As the electricity was cut off, his teachers shouted as loud as they could to gather all the students in the school onto the playground. Although some were wounded by falling objects or injured while running out, they at least escaped death.
Thousands of people, young and old, were buried in ruins, mostly in the small cities and counties, such as Wenchuan, Beichuan, Dujiangyan, Anxian and Qingchuan, which are surrounded(包围) by hills and mountains.
By last Friday, around 19,000 people died because of the earthquake, which is the worst in China in 30 years. And the number is still rising.
More than 100,000 troops have continued to arrive at destroyed areas since the day after the quake hit. And more neighboring people were doing all they can to offer help.
Kang and his parents were among them. They drove in rain to Anxian County, an hour drive away from Mianyang, with water, instant noodles and plastic for building tents. Kang’s family finally found his terrified grandparents in Anxian on Wednesday morning.
“We first thought the worst had happened to my grandparents. But they had a narrow escape and were rescued by kind people, who were completely unknown to us. We are thankful to them and hope to do whatever we could to help others,” said Kang.

The underlined word “terror” in Paragraph 1 probably means “_______ ” .

A.fear B.peace C.anger D.power

From the passage, we can learn Kang’s grandparents were rescued by ________.

A.some neighbours B.Kang Heng and his classmates
C.some kind people D.Kang Heng and his parents

For many centuries,countless scholars have asked the question:What is beauty? As designers update the latest fashions and artists create their masterpieces, what is considered beautiful changes at an alarming pace. Fifty years ago, the full-figured American actress Marilyn Monroe was a symbol of the American aesthetic(美学的)value;today, many Hollywood actresses different in appearance from Marilyn’s have taken her place. However,aesthetic values not only differ from generation to generation,but do so along cultural lines as well. Often, what is considered hating one civilization is just the aesthetic appeal in another. Thus it is difficult to give an absolute definition(定义)of beauty.
As fundamental(基础的)physicists,my colleagues and I like to believe that we are involved in a search for a beauty that affects definition. The beauty that we search for is not what is set up through the work of people and subject to the tastes, but rather what has been laid down by nature Physics allows its students to look past outer appearances,into a deeper beauty. As a human being, I am attracted by the visual appeal of a wave crashing on the beach. As a physicist, however I am able to see the deeper beauty of the physical laws that govern such a phenomenon.
In truth,since Albert Einstein put forward the idea that there might be one main physical theory that governs the universe,aesthetics have become a driving force in modern physics. Einstein and other later physicists have discovered that:Nature, as its most fundamental level,is beautifully constructed. The extraordinary simplicity (朴素)of the laws that govern the universe is really breathtaking. As Einstein said, it would seem more likely that we should find ourselves living in a “chaotic (无秩序曲)world,in no way graspable(能理解的) through thinking”. Yet we are now closer than ever to a full understanding of the universe’s beautiful clockwork. As new discoveries and technologies allow us to examine the physical world on deeper and deeper levels,we find that the beauty itself becomes much deeper.
The reference to “Marilyn Monroe” in Paragraph 2 mainly serves to___________.

A.provide an example of today’s beauty standards
B.show there is no fixed definition of aesthetics
C.compare traditions of the East to the West
D.discuss her abilities as an actress

B.To highlight the range of Einstein’s influence.
C.To show that Einstein doubted the beauty of physics.
D.To stress the very simplicity of the laws of the universe.

The passage is mainly to___________.

A.present a special way of seeing beauty
B.emphasize the influence of physics
C.discuss the awareness of cross-culture
D.argue the traditional ideas on value

In the countries of South and Southeast Asia, the elephant has been an important part of the culture, economy and religion for centuries. And nowhere more so than in Thailand. Unlike its African cousin, the Asian elephant is easily domesticated(驯化). The rare so-called white elephants have actually lent the power of royalty (皇室)to its rulers,and until the 1920s the national flag was a white elephant on a red background. To the early Western visitors, the country's romantic name was“ Land of the White Elephant".
Today, however, the story is very different. Out of work and out of land, the Thai elephant struggles for survival in a nation that no longer needs it. The elephant has found itself more or less deserted by previous owners who have moved on to a different economic world and a society in the western part. And while the elephant's problems began many years ago, now it has a very low national advantage.
How does the national symbol turn into ignored animals? It is a story of worse environment and the changing lives of the Thais themselves. According to Richard Lair, Thailand's expert on the Asian elephant and author of the report Gone Astray, at the turn of the last century, there may well have been as many as 100,000 national elephants in the country.
In the north of Thailand alone, it was estimated(估计)that more than 20,000 elephants were employed in transport, 1,000 of them alone on the road between the cities of Chiang Mai and Chiang Saen.
This was at a time when 90 percent of Thailand was still forest---a habitat that not only supported the animals but also made them necessary to carry goods and people. Nothing ploughs through thick forest better than lots of sure-footed elephants.
By 1950 the elephant population had dropped, but still to the number of 13, 397. However, today there are probably no more than 3,800, with another l,350 wandering free in the national parks. But now, Thailand's forest covers only 20 percent of the land. This deforestation(采伐森林)is the central point of the elephant's difficult situation, for it has effectively put the animals out of work. This century, as the road network grew, the elephant's role as a beast of burden decreased.
What can we know about African elephants from the passage?

A.It is of little value to domesticate them.
B.It is hard to domesticate them.
C.They are living a better life than Asian elephants.
D.Their fate is quite similar to that of Asian elephants.

Why is the Thai elephant "out of work", according to the author?

A.Because there are too many elephants but too few jobs.
B.Because the elephants can't do labor work any longer.
C.Because the government pays little attention to the problem.
D.Because the elephants are no longer useful to their owners.

The passage is most probably from ________.

A.a travel guide
B.a history book
C.a popular science magazine
D.an official announcement

Make Up Your Mind to Succeed
Kind-hearted parents have unknowingly left their children defenseless against failure. The generation born between 1980 and 2001 grew up playing sports where scores and performance were played down because “everyone’s winner.” And their report cards sounded more positive than ever before. As a result, Stanford University professor Carol Dweck, PhD, calls them “the overpraised generation. ”
Dweck has been studying how people deal with failure for 40 years. Her research has led her to find out two clearly different mind-sets that have a great effect on how we react to it. Here’s how they work:
A fixed mind-set is grounded in the belief that talent is genetic(遗传的) – you’re a born artist, point guard, or numbers person. The fixed mind-set believes he’s sure to succeed without much effort and regards failure as personal shame. When things get difficult, he’s quick to blame, lie, and even stay away from future difficulties.
On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible. Because the ego (自尊) isn’t on the line as much, the growth mind-set sees failure as a chance rather than shame. When faced with a difficulty, he’s quick to rethink, change and try again. In fact, he enjoys this experience.
We are all born with growth mind-sets. Otherwise, we wouldn’t be able to live in the world. But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise. Dweck’s book, Mind-set: The New Psychology of Success, and online instructional program explain this in depth. But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure.
What does the author think about the present generation?

A.They don’t do well at school.
B.They are often misunderstood.
C.They are eager to win in sports.
D.They are given too much praise.

A fixed mind-set person is probably one who ___ .

A.doesn’t want to work hard
B.cares a lot about personal safety
C.cannot share his ideas with others
D.can succeed with the help of teachers

What does the growth mind-set believe?

A.Admitting failure is shameful.
B.Talent comes with one’s birth.
C.Scores should be highly valued.
D.Getting over difficulties is enjoyable.

What should parents do for their children based on Dweck’s study?

A.Encourage them to learn from failures.
B.Prevent them from making mistakes.
C.Guide them in doing little things.
D.Help them grow with praise.
