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

Nobody likes home economics (家政学). But restoring the program could help us in the fight against obesity and chronic (慢性的) diseases today.
The home economics movement was founded on the belief that housework and food preparation were important subjects that should be studied scientifically. The first classes occurred in the agricultural and technical colleges that were built in the 1860s. When most departments of universities rejected women, home economics was a back door into higher education.
Indeed, in the early 20th century, home economics was a serious subject When few people understood germ (微生物) theory and almost no one had heard of vitamins, home economics classes offered vital information about washing hands regularly, eating fruits and vegetables and not feeding coffee to babies.
However, today we remember only the fixed ideas about home economics, forgetting the movement’s most important lessons on healthy eating and cooking. Too many Americans simply don’t know how to cook. Our diets, consisting of highly processed foods made cheaply outside the home, have contributed to many serious health problems. In the last decade, many cities and states have tried to tax junk food heavily or to ban the use of food stamps (食品券) to buy soda. Clearly, many people are doubtful about any governmental steps to promote healthy eating. But what if the government put the tools of obesity prevention in the hands of children themselves by teaching them how to cook?
My first experience with home economics happened two decades ago when I was a seventh grader in a North Carolina public school. A year later, my father’s job took our family to Wales, where I attended a large school for a few months. It was the first time I had ever really cooked anything. I remember that it was fun, and with an instructor standing by, it wasn’t hard. Those lessons stuck with me when I first started cooking for my husband and myself after college and they still do. Teaching cooking in public schools can help solve some problems facing Americans t day. The history of home economics shows it’s possible.

It’s hard not to feel cheated and over-charged when you receive unexpected roaming (漫游) charges while traveling abroad—whether they come from making phone calls or checking e-mails.
Jeff Gardner received an $ 11,000 bill from Verizon after spending four days in Jamaica. Before the trip, Mr. Gardner, who runs a fly-fishing business in Grayling, Michigan, said he called Verizon to find out what it would cost to use his cellphone for calls and his wireless card to check e-mails while in Jamaica. He said he was told that calls would be about $ 2 a minute and that there would be no extra charges for data as he was on an unlimited plan. The latter part turned out to be wrong.
“I don’t mind paying a fair amount for fair service, but $11,000 for four days is ridiculous,” said Mr. Gardner, who used his phone carefully and economically on the trip. He also tried to check and send e-mails using his wireless card, but quickly gave up after the e-mails didn’t go through. Still, his Verizon bill said more than 500,000 kilobytes (千字节) of data was delivered while he was in Jamaica, an amount Mr. Gardner said is 100 times what he normally uses in a month.
As travelers increasingly use smart phones abroad in the same way they do at home—to check e-mails, update Facebook and Twitter and pull up online maps—many are facing costly roaming fees, which providers charge when customers use their phones outside their service area. In fact, roaming charges have gotten so out of hand that the Federal Communications Commission has proposed a plan that would require wireless companies to send their customers a voice or text message when they are approaching their plan’s limit, when they have reached that limit and when they are starting to result in roaming fees.
Why did Jeff Gardner call Verizon before his trip to Jamaica?

A.To hand over his business.
B.To check his cellphone bill
C.To find out information about Jamaica.
D.To find out information about roaming charges.

What does the underlined sentence in Paragraph 2 mean?

During the trip, Jeff Gardner______.

A.was careless with phone use
B.delivered no more data than at home
C.received quite poor e-mail services
D.frequently used his wireless card to send e-mails

What should wireless companies do according to the Federal Communications Commission?

A.Make customers know when they’re outside their service area.
B.Get customers informed when they’re near the limit of their plan.
C.Stop serving customers when they’ve reached their plan’s limit.
D.Limit some services to reduce the amount of roaming charges abroad.

What’s a “gift”? If you look it up in the dictionary, you’ll see that it’s another word for a present. For example, “They brought him some gifts.” However, if you’re German, “gift” means something completely different: poison!
This word “gift” is an example of a false friend--- a word that looks the same in two languages, but which actually has two different meanings. As English is basically a mixture of German, French and Latin, there are many words that are similar in these languages. For example, the English word “education” is “education” in Spanish. And the English words “word, book, nine, house” are “Wort, Buch, Neun, Haus” in german.
These similar-looking words can be very helpful when learning other languages --- they’re our “friends”. However, sometimes they can turn out or be “false friends”. Here are a few examples.
In English, someone who is “sensible” thinks before they act and shows good judgement. For example , “The sensible thing to do would be to consult a lawyer.” However, in Spanish, “sensible ” means “sensitive” (showing understanding of other people’s problems, needs or feelings).
The English word “coin” refers to a piece of money made of metal. For example, “I had a few coins in my pocket.” But the French word “coin” means “corner”.
The English word “library” is a place where you can go to borrow books. For example, “I borrowed six books from the library.” But the Spanish word “libreria” refers to a bookshop (where you buy books).
The English word “actually” means “in fact”. For example, “Actually I’m not Italian, I’m form American.” But the Spanish word “actualmente” means “currently” or “at the moment”.
Finally, the English word “embarrassed” means “ashamed”. For example, “They looked a bit embarrassed.” However, the Spanish term “embarazada” means “pregnant” (with a child).
We can learn from the first two paragraphs that English _______.

A.is easy to master
B.is simpler than Spanish
C.has a complex background
D.has changed greatly throughout history

Which of the following pairs of words are true friends according to the author?

A.Nine and Neun. B.Library and libreria.
C.Actually and actualmente. D.Embarrassed and embarazada.

According to the text, in Spanish ______.

A.“coin” means “corner”
B.“gift” refers to something negative
C.“educacion” simply means “book”
D.“sensible” doesn’t necessarily means “wise”

The author develops the text mainly by ______.

A.following the order of space B.comparing different ideas
C.providing typical examples D.analyzing the cause and effect

You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community.
"How Yoga Can Wreck Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself.
The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison.
Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself.
The reasons that yoga causes "serious injury”, according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures.
Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there.
We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer.
The underlined word is best replaced by __.

A.Injure B.Benefit C.Push D.Shape

What does author mainly want to tell us in the 3rd paragraph?

A.All physical activities are equally harmful.
B.Yoga causes much less injuries than other physical activities.
C.Similar researches have been done before.
D.Yoga, like any other form of exercise, can hurt people.

Which is not mentioned among the reasons for yoga being likely to cause injury?

A.Teachers lack the knowledge of students’ limits.
B.Modern lifestyle decreases our flexibility.
C.The body doesn’t tell when you are in real pain.
D.Students themselves might not be in good physical condition.

What is the author’s attitude towards practicing yoga?

A.It’s a shame not to practice yoga.
B.One should push the limits in order to be perfect.
C.The majority should give up yoga for it may cause harm.
D.One should enjoy the physical and mental benefit that yoga brings.
