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

Jerry was a unique manager because he had several waiters who had followed him around from restaurant to restaurant. The reason the waiters followed Jerry was because of his attitude. He was a natural motivator. If an employee was having a bad day, Jerry was there telling the employee how to look on the positive side of the situation.
Seeing this style really made me curious, so one day I went up to Jerry and asked him, “I don’t get it! You can’t be a positive person all of the time. How do you do it?” Jerry replied, “Each morning I wake up and say to myself, ‘Jerry, you have two choices today. You can choose to be in a good mood or you can choose to be in a bad mood.’ I choose to be in a good mood. Each time something bad happens, I can choose to be a victim or I can choose to learn from it. I choose to learn from it. Every time someone comes to me complaining, I can choose to accept their complaining or I can point out the positive side of life. I choose the positive side of life. The bottom line: It’s your choice how you live life.” I reflected on what Jerry said. Later, I left the restaurant industry to start my own business. We lost touch, but I often thought about him when I made a choice about life.
Several years later, I heard that Jerry did something you are never supposed to do in a restaurant business: he left the back door open one morning and was held up at gun point by three armed robbers. While trying to open the safe, he forgot the password, nervous. The robbers panicked and shot him. Luckily, Jerry was found relatively quickly and rushed to the local hospital. After 18 hours of surgery and weeks of intensive care, Jerry was released from the hospital with fragments（碎片） of the bullets still in his body.
I saw Jerry about six months after the accident. When I asked him how he was, he replied, “The first thing that went through my mind was that I should have locked the back door,” Jerry replied. “Then, as I lay on the floor, I remembered that I had two choices: I could choose to live, or I could choose to die. I chose to live.” “Weren’t you scared? Did you lose consciousness?” I asked. Jerry continued, “The doctors and nurses were great. They kept telling me I was going to be fine. But when they wheeled me into the emergency room and I saw the expressions on the faces of the doctors and nurses, I got really scared. I knew I needed to take action.”
“What did you do?” I asked. “Well, there was a big, strong nurse shouting questions at me,” said Jerry. “She asked if I was allergic (过敏的)to anything. “Yes,” I replied. The doctors and nurses stopped working as they waited for my reply. I took a deep breath and yelled, “Bullets!” Over their laughter, I told them. “I am choosing to live. Operate on me as if I am alive, not dead.”
Jerry lived thanks to the skill of his doctors, but also because of his amazing attitude. I learned from him that every day we have the choice to live fully.

Animals are considered to be endangered if the species is close to extinction throughout all or most of its environment. Animals become endangered for a variety of reasons.
Some animals become endangered when their habitats contain resources for humans. For example, commercial forest cutting in the Amazon Rainforest has seriously reduced the population of many animal species and lead to the extinction of other groups. Land itself is an important resource to humans since it provides us with living space, and when people replace animal habitats with human habitats, it can lead to larger loss of natural species.
Commercial and industrial operations may reduce land or water for animals and pollute their environment. Due to water pollution, the baiji, a fresh water dolphin native to China, was declared extinct, meaning it’s unlikely the population can recover. Even noise pollution from human activities can lead to the disorder of animal behavior.
Another cause that makes animals become endangered is over-fishing or over-hunting. Over-hunting whales led to near extinction of many species of whales.
The introduction of a non-native species to a habitat may make animals become endangered. The native species may not defend against a new one, and the effects can be dangerous. In Australia, the introduction of the common house cat led to the extinction of the red-fronted parakeet and has seriously damaged the populations of several small animals.
Introduced species can also bring new diseases with them. As a result, animals become endangered. Native animals may not have the power to fight against non-native diseases, and population levels can suffer. Another cause of disease is human-introduced chemicals. The use of DDT is believed to be one of the leading causes in driving the California Condor to near extinction.
When animals become endangered, the entire food chain can be affected. For example, in 2008 disease seriously harmed the honeybee, which is largely responsible for pollinating(授花粉) plants, including many fruits and vegetables. Without their pollination, a very large part of the human diet could be reduced. In fact, if the honeybee should become extinct, our life would be affected and billions of dollars would be lost. Therefore, many people argue that when animals become endangered it is in man’s own self-interest to protect them.
The passage is mainly about ______.

A．ways of protecting animals’ habitats

B．effects caused by species endangerment

C．dangers of bringing in non-native species

D．reasons why animals become endangered

Which of the following examples shows that environmental pollution may cause species endangerment?

A．The extinction of the whales.

B．The extinction of the red-fronted parakeet.

C．The decreasing population of the dolphin.

D．The effect of the honeybee on the human diet.

Why is it dangerous to introduce a non-native species to a habitat?

A．Native species are likely to die from the new diseases.

B．It’s hard for non-native species to survive.

C．Non-native species will take up more space.

D．Native species are so powerful for non-native species.

The California Condor is in danger of dying out because of ______.

A．loss of habitat	B．harmful chemicals
C．forest cutting	D．unfamiliar diseases

We can infer from the last paragraph that ______.

A．humans are to blame for species extinction

B．small animals mean little to the whole food chain

C．protection of the honeybee has cost billions of dollars

D．humans protect animals for the benefit of themselves

Most likely, you aren’t the family breadwinner. But doing a small job or getting a weekly allowance (零花钱) would put some money in your pocket. For kids and grown-ups alike, money is easy to spend. If you aren’t careful, it can be going in no time.
　　Being responsible with your money is an important skill to learn — and the sooner you start the better. Whether you are tracking your spending or saving for something special, creating a budget can help you deal with your expenses and plan for the future. All you need are paper and a pencil — and some self-control.
　　First, take a look at our sample monthly budget. Then, use a separate sheet of paper to plan your own. In the first two columns (栏), list your sources (来源) of income and how much you expect to earn from them. In the third and fourth columns, list what you expect to spend your money on and the amount.
　　The left-hand total should be more than or equal to the right-hand total. If it is, you have an effective budget. Budgets are not complex, but sticking to them can be tough. When planning your budget, be realistic about your expenses. If you know that you drop $18 at a movie, don’t write $12 in that space simply because you wish you were spending less.
　　If you are eyeing a big purchase, such as a $150 skateboard, spend less and save more until you have the total amount. No matter how attractive it may be, avoid spending your savings. One day, you will thank yourself!

阅读下面短文，从各题所给的A、B、C、D四个选项中选出最佳答案。
As summer comes near, many children are really happy to forget about school for a few months. However, they might be taking that goal too seriously. Studies have found that children often forget between one and three months’ worth of school learning during the summer months. Spelling and math abilities drop off the most, while reading is not really influenced by the time off. The main reason for this is because most children sometimes read outside of the classroom, whether newspapers, magazines, books, or video game guides. However, their math and spelling skills only get exercised in the school setting.
The first purpose of summer holidays was to let farm children have time off to help work in the fields during the growing season, but this reason is no longer a good one since fewer kids actually work on farms today. Some cities in the United States, such as Los Angeles, have moved to a year-round school timetable, which may help reduce the loss of school skills that happens during the long summer holiday. To improve skills and to keep a good level of preparation, headmasters suggest trips to museums, summer camps, holidays with educational value, and visits to libraries to keep kids interested throughout the summer.
There are other educational systems that provide holidays while still keeping students’ skills up to date. For example, in Japan, students attend class for seven weeks in a row, followed by two weeks of holiday. This continues the whole year. In Italy, students attend class six days per week, but finish at 1: 30 pm each day, so that school does not run their life the way that it does in America, where students attend high school from 7: 45 am until 3: 00 pm each weekday. In areas where there are not enough classrooms—in Afghanistan or Somalia, for example—older students attend classes in the morning while the younger kids go to school in the afternoon.
Headmasters fear that the three-month summer holiday stops the flow of learning. Just as students become used to new math problems or new ideas in reading, writing, or thinking skills, they “shut down” during the summer holiday. When they go back to school after the long summer holiday, they take up to two months to return to their previous (先前的) level of skill. So the debate continues: whether to continue holidays or to make changes based on the Los Angeles or the Japanese models.
Which skills suffer the most over the summer holidays?

A．Math and reading.	B．Math and spelling.
C．Reading and writing.	D．Reading and thinking.

What can we learn about the first purpose of summer holidays?

A．It is still widely acceptable now.	B．It was popular in some cities.
C．It is not a good reason for city kids.	D．It was more for teachers than for students.

The underlined phrase “shut down” in the last paragraph probably means __________.

A．stop learning	B．get sick
C．go on reading	D．focus on studies

What can we infer from the passage?

A．Parents always read to their kids to keep reading skills.

B．Summer holidays lead to the loss of all the school skills.

C．Students love holidays and get their mind off learning in holidays.

D．In Italy students attend classes in the late afternoon six days a week.

A．Became better.	B．Changed unexpectedly.
C．Went worse.	D．Progressed unsteadily.
