单选题 The phrase almost completes itself: midlife crisis. It's the stage in the middle of the journey when people feel youth vanishing, their prospects narrowing and death approaching. There's only one problem with the cliché(套话). It isn't true. 'In fact, there is almost no hard evidence for midlife crisis other than a few small pilot studies conducted decades ago,' Barbara Hagerty writes in her new book, Life Reimagined. The vast bulk of the research shows that there may be a pause, or a shifting of gears in the 40s or 50s, but this shift 'can be exciting, rather than terrifying'. Barbara Hagerty looks at some of the features of people who turn midlife into a rebirth. They break routines, because 'autopilot is death'. They choose purpose over happiness—having a clear sense of purpose even reduces the risk of Alzheimer's disease. They give priority to relationships, as careers often recede (逐渐淡化). Life Reimagined paints a picture of middle age that is far from gloomy. Midlife seems like the second big phase of decision-making. Your identity has been formed; you've built up your resources; and now you have the chance to take the big risks precisely because your foundation is already secure. Karl Barth described midlife precisely this way. At middle age, he wrote, 'the sowing is behind; now is the time to reap. The run has been taken; now is the time to leap. Preparation has been made; now is the time for the venture of the work itself.' The middle-aged person, Barth continued, can see death in the distance, but moves with a 'measured haste' to get big new things done while there is still time. What Barth wrote decades ago is even truer today. People are healthy and energetic longer. We have presidential candidates running for their first term in office at age 68, 69 and 74. A longer lifespan is changing the narrative structure of life itself. What could have been considered the beginning of a descent is now a potential turning point—the turning point you are most equipped to take full advantage of.

单选题 The planet is getting lusher, and we are responsible. Carbon dioxide generated by human activity is stimulating photosynthesis (光合作用) and causing a beneficial greening of the Earth's surface. For the first time, researchers claim to have shown that the increase in plant cover is due to this 'CO2 fertilization effect' rather than other causes. However, it remains unclear whether the effect can counter any negative consequences of global warming, such as the spread of deserts. Recent satellite studies have shown that the planet is harboring more vegetation overall, but pinning down the cause has been difficult. Factors such as higher temperatures, extra rainfall, and an increase in atmospheric CO2—which helps plants use water more efficiently—could all be boosting vegetation. To home in on the effect of CO2, Randall Donohue of Australia's national research institute, the CSIRO in Canberra, monitored vegetation at the edges of deserts in Australia, southern Africa, the US Southwest, North Africa, the Middle East and central Asia. These are regions where there is ample warmth and sunlight, but only just enough rainfall for vegetation to grow, so any change in plant cover must be the result of a change in rainfall patterns or CO2 levels, or both. If CO2 levels were constant, then the amount of vegetation per unit of rainfall ought to be constant, too. However, the team found that this figure rose by 11 per cent in these areas between 1982 and 2010, mirroring the rise in CO2 (Geophysical Research Letters, doi. org/mqx). Donohue says this lends 'strong support' to the idea that CO2 fertilization drove the greening. Climate change studies have predicted that many dry areas will get drier and that some deserts will expand. Donohue's findings make this less certain. However, the greening effect may not apply to the world's driest regions. Beth Newingham of the University of Idaho, Moscow, recently published the result of a 10-year experiment involving a greenhouse set up in the Mojave Desert of Nevada. She found 'no sustained increase in biomass' when extra CO2 was pumped into the greenhouse. 'You cannot assume that all these deserts respond the same,' she says. 'Enough water needs to be present for the plants to respond at all.'

单选题New research finds that nearly 5200 kids are treated in an emergency department each year after falling from a window. That's 14 kids a day, according to a study published Monday. Typical hospital admission 25 for childhood injuries stand at 5%, but 25% of window-related injuries end up requiring care in the hospital, for pretty obvious reasons: a fall from a window can be 26 . New York City landlords are required to 27 the guards, which resemble horizontal jail bars and cover the bottom half of a window to forma barrier that prevents kids from 28 out. Programs like Children Can't Fly in New York and Kids Can't Fly in Boston, which have raised public 29 about the need for window guards, especially in high-rise buildings, have helped contribute to dramatic 30 in the number of children falling out of windows in those cities. Parents can also use window stops to 31 children. Stops are screwed into the window frame and block the window from sliding too far upward. Parents should further limit children's 32 to windows by moving dressers, beds and tables away from the openings; many kids fell through a window they accessed by climbing onto furniture. It's also important to be 33 watchful when the weather is warm since that's when windows tend to be open. And don't make the mistake of thinking that a window screen 34 any protection. It found that screens did not prevent falls. A. access B. account C. anxiety D. awareness E. crawling F. deadly G. entirely H. injurious I. install J. offers K. particularly L. protect M. rates N. reductions O. slipping
