问题     We keep an eye out for wonders, my daughter and I, every morning as we walk down our farm lane to meet the school bus. And wherever we find them, they reflect the magic of water: a spider web drooping with dew like a necklace. A rain-colored heron rising from the creek bank. One astonishing morning, we had a visitation of frogs. Dozens of them hurtled up from the grass ahead of our feet, launching themselves, white-bellied, in bouncing arcs, as if we’d been caught in a downpour of amphibians. It seemed to mark the dawning of some new watery age. On another day we met a snapping turtle in his olive drab armor. Normally this is a pond-locked creature, but some ambition had moved him onto our gravel lane, using the rainy week as a passport from our farm to somewhere else.
    The little, nameless creek tumbling through our hollow holds us in bondage. Before we came to southern Appalachia, we lived for years in Arizona, where a permanent brook of that size would merit a nature preserve. In the Grand Canyon State, every license plate reminded us that water changes the face of the land, splitting open rock desert like a peach, leaving mile-deep gashes of infinite hue. Cities there function like space stations, importing every ounce of fresh water from distant rivers. But such is the human inclination to take water as a birthright that public fountains still may bubble in Arizona’s town squares and farmers there raise thirsty crops. Retirees from rainier climates irrigate green lawns that impersonate the grasslands they left behind. The truth encroaches on all the fantasies, though, when desert residents wait months between rains, watching cacti tighten their belts and roadrunners skirmish over precious beads from a dripping garden faucet. Water is life. It’s the salty stock of our origins, the pounding circulatory system of the world. It makes up two-thirds of our bodies, just like the map of the world; our vital fluids are saline, like the ocean. The apple doesn’t fall far from the tree.
    Even while we take Mother Water for granted, humans understand in our bones that she is the boss. We stake our civilizations on the coasts and mighty rivers. Our deepest dread is the threat of having too little moisture — or too much. We’ve lately raised the Earth’s average temperature by 0.74°C, a number that sounds inconsequential. But these words do not: flood, drought, hurricane, rising sea levels, bursting levees. Water is the visible face of climate and, therefore, climate change. Shifting rain patterns flood some regions and dry up others as nature demonstrates a grave physics lesson: Hot air holds more water molecules than cold.
    The results are in plain sight along beaten coasts from Louisiana to the Philippines as super-warmed air above the ocean brews superstorms, the likes of which we have never known. In arid places the same physics amplify evaporation and drought, visible in the dust-dry farms of the Murray-Darling River Basin in Australia. On top of the Himalaya, glaciers whose melt water sustains vast populations are dwindling. The snapping turtle I met on my lane may have been looking for higher ground. Last summer brought us a string of floods that left tomatoes spoilt on the vine and our farmers needing disaster relief for the third consecutive year. The past decade has brought us more extreme storms than ever before, of the kind that dump many inches in a day, laying down crops and utility poles and great sodden oaks whose roots cannot find purchase in the saturated ground. The word "disaster" seems to mock us. After enough repetitions of shocking weather, we can’t remain indefinitely shocked.
    How can the world shift beneath our feet? All we know is founded on its rhythms: Water will flow from the snowcapped mountains, rain and sun will arrive in their proper seasons. Humans first formed our tongues around language, surely, for the purpose of explaining these constants to our children. What should we tell them now? That "reliable" has been rained out, or died of thirst? When the Earth seems to raise its own voice to the pitch of a gale, have we the ears to listen?
A suitable title for the passage would be
选项 A、The Causes of Disasters.
B、The Evolution of Creatures.
C、Water Resource Is Limited.
D、Water Is Life.
答案D
解析 主旨题。考查对整个文章主旨内容的把握。A项“灾害泛滥的原因”，文中虽然提到自然灾害，但是没具体分析其产生的原因；本文并没有涉及生物的进化，故B项可以排除；C项“水资源有限”偏离文中主要围绕水资源的作用这一主题，而D项“水即是生命”在文中已有提到，故为正确答案。
