1 . Is It Worth Buying Organic Food?

Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels (标签). However, if you think paying a little more for organic food gets you a more nutritious (有营养的) and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren’t necessarily more nutritious, and they’re no less likely to suffer from disease-causing bacteria, either.

The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. “We did not find strong evidence that organic food is more nutritious or healthier,” says Dr. Crystal Smith-Spangler from Stanford. “So consumers shouldn’t assume that one type of food has a lower risk or is safer.”

For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats.

While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends.

Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn’t always translate into a more nutritious or healthier product. The U.S. Department of Agriculture (USDA) states that “Whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste.” Fresh food is at least as good as anything marketed as organic.

2 . Overlooking the Davis—Gant Varsity Soccer Field, a bed of overturned soil waits for further development. In a few years, this area will become a natural habitat and a playground for animals and residents. This peaceful area didn’t appear naturally, but through planning and action taken by Catlin Gabel’s Tiny Forest project launched by teacher Patrick Walsh.

Forests typically take hundreds of years to mature, with four stages of growth. “Tiny forests flatten out time through the planting of all four layers (层),” Walsh explained. The end result is a fast-growing, native forest in about 20 years. Over 600 plants from 43 species will be planted in the tiny forest, the first one in Oregon.

Walsh was inspired to build a tiny forest after hearing about this idea, which emerged in Japan and has taken hold in North America. He shared his vision with seniors in his class. The seniors researched tiny forests and made a proposal resulting in Clean Water Services donating 60 trees and $5,000 from the National Oceanic and Atmospheric Administration. Armed with these resources, Walsh and the students started working. “Something I didn’t really expect was the outpouring of students’ enthusiasm. Seeing students from all grades volunteered to contribute to the ‘dirty work’ really blew me away,” Walsh said.

Senior Megan Cover has been at the school since the first grade. “I’ll graduate after working on this project, which is surely sad, but it’s really rewarding and great to be a part of this project and to do my bit. We’re creating this educational space for many young kids,” Cover said.

Walsh summed up his goal of the project, which is to build a place where students can enjoy and learn about nature. “The forest will obviously not solve climate change, but it will deserve the efforts if the kids think about climate change and remember the importance of reforestation and trees when they look outside at the forest.”

3. How does Megan Cover feel about the project?

A．Proud.

B．Regretful.

C．Grateful.

D．Disappointed.

4. What does Walsh want the forest to function as for the students?

A．A model.

B．A reminder.

C．A resource.

D．A witness.

3 . What makes people so special? Tool use, self-consciousness, language, and culture are high on the list, but in fact all of these characteristics can be found elsewhere in the animal kingdom. Humans and apes are close relatives, so it is perhaps not surprising that chimpanzees use tools or that gorillas (大猩猩) have a sense of fair play, even rejecting carrots (which they normally accept) when they see their neighbors getting grapes. But the qualities that we often think of as uniquely human exist not just on land, but in the ocean as well.

Among the invertebrates, octopuses (八爪鱼) are known for their intelligence, even exhibiting evidence of playfulness, tool use, and personality. But these skilled predators live alone and consequently lack culture. Dolphins, on the other hand, are large-brained, long-living, social- group-based predators, and it is here that we find the greatest similarity to human-like culture and awareness.

Culture depends on the ability of animals to pass on things they have learned to others. Many animals have culture in this sense, but what sets dolphins apart is what they pass on. Some bottlenose dolphins hold sponges in their mouths that they use as tools to sweep for fish hiding on the ocean floor. This ability is handed down through generations (especially in females), with some families — grandmother, mother, and daughter — all feeding in this highly specialized way.

Another characteristic that dolphins share with humans is their ability to recognize themselves in a mirror. When facing a mirror, most animals behave as though they are interacting with another individual. Even in humans, the ability to recognize that the image in a mirror is oneself does not occur before the age of 18 months. Dolphins not only recognize themselves, but if a black mark is put on the body of a dolphin, it will spend extra time at the mirror to look at the mark.

A．They tend to hunt in groups.

B．Their hunting skills are passed down.

C．Their learning environment is favourable.

D．Their families are typically female-controlled.

4. What can be inferred from the last paragraph?

A．Dolphins enjoy looking at their own reflection in the mirror.

B．Dolphins are as intelligent as a typical 18-month-old human baby.

C．Dolphins are generally regarded as the most advanced non-human species.

D．Dolphins’ ability to recognize their own reflection is a higher-order mental skill.

5 . You must have heard about animal migration (迁徙),such as Wildebeests dash across Africa; Monarch butterflies fly across the Americas... But did you know that forests migrate, too?

In his new book The Journeys of Trees, science writer Zach St. George explores an extremely slow migration, as forests creep inch by inch to more pleasant places.

“The migration of a forest is just many trees sprouting (发芽) in the same direction,” St. George writes. “Through the fossils that ancient forests left behind, scientists can track their movement over thousands of years. They move back and forth across continents, sometimes following the same route more than once, like migrating birds or whales.” This has happened over thousands of years, and climate change tends to be the driving force.

Of course, today, climate change is speeding up, and trees can’ t keep pace. Take California for example: It’s getting hotter and drier and scientists estimate that before too long, Sequoia National Park may not be able to keep giant sequoias (巨杉).

“The scientists there had never seen anything like it” St. George says. “They worried, and I think at some point we will lose these ancient trees and that we will have to think about what we do with the places, and whether we should plant new groves where they are easy to grow.”

This is known as “assisted migration” —humans planting trees in other places where they’ re more likely to flourish. But this process carries risks—people can accidentally introduce insects and diseases to new places, where they may wipe out entire native populations. So, St. George writes, there’ s a debate among conservationists and foresters today: Should humans help the trees escape?

“There may be cases where people are probably going to step in and help species move to places where they’ll be more suitable in the future,”St. George says.“So far, there are no huge movements of citizen groups moving trees north. But that is kind of one vision of the future that the people I interview hope to see.”

D．It often follows certain migrating species.

2. Why does the author mention Sequoia National Park?

B．To stress the park is able to keep giant sequoias.

C．To state scientists are hopeful about the environment.

D．To show trees fail to adapt to climate change.

3. What does the underlined word “flourish” in Paragraph 6 mean?

A．Grow well.	B．Become valuable.
C．Develop rapidly.	D．Escape diseases.

4. What’s St. George’ s attitude towards helping the trees escape?

A．Supportive.	B．Objective.
C．Skeptical.	D．Disapproving.

6 . Losing your ability to think and remember is pretty frightening. We know the risk of dementia (痴呆症) increases with age. But if you have memory slips, you probably needn’t worry. There are pretty clear differences between signs of dementia and age-­related memory loss.

After age 50, it’s quite common to have trouble remembering the names of people, places and things quickly, says Dr. Kirk Daffner of Brigham and Women’s Hospital in Boston.

The brain ages just like the rest of the body. Certain parts become smaller, especially areas in the brain that are important to learning, memory and planning. Changes in brain cells can affect communication between different regions of the brain. And blood flow can be reduced as blood vessels narrow.

Forgetting the name of an actor in a favorite movie, for example, is nothing to worry about. But if you forget the plot of the movie or don’t remember even seeing it, that’s far more concerning, Daffner says.

When you forget entire experiences, he says, that’s “a red flag that something more serious may be involved”. Forgetting how to operate a familiar object like a microwave oven, or forgetting how to drive to the house of a friend you’ve visited many times before can also be signs of something going wrong.

But even then, Daffner says, people shouldn’t panic. There are many things that can cause confusion and memory loss, including health problems like temporary stoppage of breathing during sleep, high blood pressure, or depression, as well as medications (药物) like antidepressants.

You don’t have to figure this out on your own. Daffner suggests going to your doctor to check on medications, health problems and other issues that could be affecting memory. And the best defense against memory loss is to try to prevent it by building up your brain’s cognitive (认知的) reserve, Daffner says.

“Read books, go to movies, take on new hobbies or activities that force one to think in novel ways.” he says. In other words, keep your brain busy and working. And also get physically active, because exercise is a widely known to boost the brain.

1. Which memory-related symptom should people take seriously?

A．Totally forgetting how to do one’s daily routines.

B．Inability to recall details of one’s life experiences.

C．Failure to remember the names of movies or actors.

D．Occasionally confusing the addresses of one’s friends.

2. What should people do when signs of serious memory loss show up?

A．Check the brain’s cognitive reserve.

B．Stop medications affecting memory.

C．Turn to a professional for assistance.

D．Exercise to improve their well­being.

3. What is Dr. Daffner’s advice for fight against memory loss?

A．Having regular physical and mental checkups.

B．Taking medicine that helps boost one’s brain.

C．Engaging in known memory repair activities.

D．Staying active both physically and mentally.

4. Which of the following is closest in meaning to the underlined word “boost” in the last paragraph?

A．Reduce.

B．Benefit.

D．Depress.

7 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

9 . Once upon a time, a daughter complained to her father that her senior high school life was unhappy and that she was tired of struggling with homework all the time.

Her father, a chef, took her to the kitchen. He filled three pots with water and placed each on a high fire. Once the three pots began to boil, h placed potatoes, eggs and coffee beans in them. After 20 minutes, he took them out, putting the potatoes and eggs in a bowl and the coffee in a cup.

Turning to his daughter, he said, “Look closer, and touch the potatoes.” She did and noted that they were soft. He then asked her to take an egg and break it. After puling off the shell, she observed the hard-boiled egg. Finally, he asked her to taste the coffee. Its good smell brought a smile to her face.

“Father, what does this mean?” she asked. He then explained that the potatoes, the eggs and the coffee beans were in the same adversity (逆境)—the boiling water. However, each one reacted differently.

The strong and hard potato became soft and weak in boiling water. The egg was fragile, with the thin outer shell protecting its liquid until it was put in the boiling water. Then the inside of the egg became hard. However, the coffee beans were unique. After they were exposed to the boiling water, they changed the water and created something new. “Which one do you want to be like,” he asked. “When adversity knocks on your door, how will you respond?”

In life, challenges happen to us all, but the only thing that truly matters is what happens within us.
