How do scientists modify a plant so that it makes more food than its parents did? We could treat each harvest like a litter of wolf pups and select only plants bearing the fattest, richest seeds for the next season. This was the method our ancestors used to engineer rice, corn and wheat from the wild grasses they encountered.
During my childhood, advances in genetic technologies allowed scientists to identify and clone the genes responsible for repressing stem growth, leading to shorter, stronger stalks that could bear more seed—the high-yield crops that feed us today. The 21st century has brought with it a marvelous new set of high-tech tools with which to further quicken the process of artificial selection. Plant geneticists can now directly edit out or edit in sections of DNA using molecular scissors. We can minimize a plant’s weaknesses while adding to its strengths, and we don’t have to wait for seasons to pass to test the result.
It is the transformative potential of these techniques to quickly supply the next-generation crops required for upcoming climate change that has led me to believe in the safety and function of GMO plants in agricultural products. We need more GMO research to feed the world that we are creating.
I love the quiet forest that stands between my lab and my home. But I know that as a scientist, I am responsible first to humanity. We must feed, shelter and nurture one another as our first priority, and to do so, we must take advantage of our best technologies, which have always included some type of genetic modification. We must continue as before, nourishing the future as we feed ourselves, and each year plant only the very best of what we have collectively engineered. I keep the faith of my ancestors each night when I walk through the forest to my lab, and my GMO wolf does the same when she guards my way home.

（C）
Since quitting can start feelings such as guilt and shame, we often do everything possible to avoid it. “We’re taught from our earliest days that if you quit something. It means you’re a failure,”says counseling psychologist Will Meek. He, however, suggests we view quitting differently.
Quitting is like deciding to rearrange a room: you’ve grown comfortable with the status, and it can be hard to picture the end result or even see why change is necessary. And yet, there’s the upsetting feeling that you’re no longer entirely satisfied with your current circumstances, perhaps even that you’ve stopped making progress. While it’s not out of the question for feeling or regret to surface after a major refit, leaving a position, project or situation can reveal exciting possibilities, making you feel inspired and renewed.
Quitting, often happens in situations where we’re unhappy, fearful or have determined we have no other choice, factors that can have opposing effects on our health. Perhaps you find your

work unfulfilling, or you’ve jumped into a new relationship before you’re ready —and, as a result, you’re operating under intense pressure.“If stress is enduring and not managed well, it can start to take a toll.”says Meek. According to the American Psychological Association, long-term, ongoing stress can increase the risk for high blood pressure and heart attack, so walking away from whatever is causing it can deliver significant physical and emotional health benefits.“We often see a reduction in the stress hormone cortisol（应激激素皮质醇）, which can lower blood pressure and may even decrease the heart rate,”says Dr Alex Lickerman, a GP and expert on developing mental adaptability.
Leaving situations that fail to bring you joy can leave you with sufficient time to explore where your heart is truly leading you. In a study that was published in 1999, then Harvard University professor Hermina Ibarra looked at how bankers tried different roles that required new skill sets—someone who spent a lot of time dealing with computers, for instance, was asked to take on personal interactions. Subjects were especially drawn to acting out a version of their future solves through ‘imitation strategies’—an approach they compared to ‘trying on different clothes,’ Mark Franklin, the president of CareerCyles, suggests a similar approach as a way to figure out what your true desires might be in your post-quitting life and foresee your future self.“Pretend to be a certain kind of person, or go and meet others who are doing what you want to do.”he says,“Try it on, see how it feels and decide if it’s a good fit for you.”It may not feel like it at the time, but just moving on from a situation that’s not quite right can help you get back on track.
63. It can be inferred from paragraph 2 that quitting may bring us feelings of being both _______. A. guilty and ashamed C. troubled and hopeful
B. stupid and enthusiastic D. inspired and determined
64. The phrase“take a toll”（paragraph 3）can be best replaced by“_________”. A. develop mental adaptability C. keep up the pressure

C
It could be said that the age of adventure peaked with Sir Everest Shackleton the moment his ship, the Endurance, become hopelessly locked in ice on its way to Antarctica in January 1915. For ten months the 28 men aboard Shackleton’s ship waited and prayed for ice to break. When it finally did, the Endurance sank, leaving the crew homeless and adrift on a sea of ice in one of the world’s most dangerous environments.
In January 2000 a luxury ocean liner found itself similarly trapped in the cold waters off Antarctica. Argentine authorities sent off an icebreaker straight away from the nearest naval base, and in 24 hours, all 176 passengers and crew were free. The tour company’s spokesperson spun the potential disaster as a value-added reward in extreme travel. “The people on board are looking at this as sort of a great adventure,” she said.
Ever since Jon Krakauer’s book Into Thin Air made Everest a household name, the subculture of adventure has blown up like a Himalayan avalanche(雪崩) into public consciousness. Magazines promise “extreme” content, television, offers adventure programs, and the growing collective fascination with adventure has produced a flow of published accounts about the world’s greatest adventurous journey. Nowadays more and more people are interested in adventure and this mass appeal makes good business sense. Today the only thing blocking a would-be adventurer’s passage to Antarctica is the cost---- which typically runs well over $10,000.
