The morning ride，when the guides take you to beautiful，shallow lakes fullof water lilies，tends to be more active.It is unlike any other riding experience with rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face.It is truly exciting.You are very likely to come across large wild animals，too.On horseback it is possible to get quite close to elephants，giraffes and many other animals.The sense of excitement and tension levels rise suddenly though，and so does your heart rate，as you move closer to them. In the evening，rides are usually at a more relaxed and unhurried pace，with golden light streaming across the grassy delta and the animals coming out Sedateto eat and drink.ridesthough they are,at this time of day are still very impressive.As the sun's rays pass through the dust kicked up by thehorses，the romance of Africa comes to life.

]【导学号：85602076】B(2016·济南市高三模拟) People need to seek out new foods because the world has so many mouths to feed.As of 2015，there are more than seven billion people on Earth, according to the United Nations.And by 2100 that number may double.Feeding all of these people means not only improving the way foods are grown，but alsofinding new sources of nutrition. And that quest is becoming ever more urgent.If nothing changes，within 35 years，the world's appetite will be greater than the amount of foods produced.That's according to a report released last year.It was prepared by the Global Harvest Initiative，a private agriculture group based inWashington，D.C. Global warming, too, is changing food production.Scientists predict that rising temperatures will reduce the growth of important crops like wheat，corn and soybeans.Low income developing countries will be hit the hardest.When harvests fall，crops become more expensive.And since those foods are also used to feed animals like cows and pigs，meat prices，too，will rise. All over the world, researchers are racing against the clock to figure out how best to feed more people in a fastchanging world.And some surprising ideas have begun to come up.Two years ago，scientists introduced the first burger made from meat grown in a lab.The project cost more than $300，000，but it's a start.Other researchers are developing seeds that can survive high temperatures and drought.Still other are finding ways to improve the genes of meat animalsso they produce more meat and can stand the heat.A gloomy(悲观的) forecast for the planet isn't the only reason to study foods for the future.It's a creative quest that will inspire people who can think in new ways about existing plants and animals—even insects.These researchers have used their talents in ways that even they never would havepredicted.本文主要讲的是在全球变暖的环境下，人们应如何应对日益膨胀的人口的温饱问题。
