come across a powerful Aztec empire in Central Mexico，a freshly painted “Mona Lisa” in Renaissance Europe and cooler temperatures across the Northern Hemisphere (半球)This was a world in the middle of the Little Ice Age (A.D.1300 to 1850) and a period of vast European exploration now known as the Age of Discovery.But what if we could look 500 years into the future and catch sight of the Earth of the 26th century？Would the world seem as different to us as the 21st century would seem to people of the 16th century？For starters，what will the weather be like?Depending on whom you ask，the 26th century will either be a little cold or terribly hot.Some suggest that by the 2500s，Earths climate will have cooled back down to near Little Ice Age conditions.Other studies predict that ongoing climate change and fossil fuel use will make much of the planet too hot for human life by 2300.Some experts date the beginning of human climate change back to the Industrial Revolution in the 1800s，others to slashandburn (刀耕火种的) agricultural Practices in prehistoric times.Either way，toolusing humans change their environmentand our 26th_century_tools might be quite impressive indeed.Theoretical physicist Michio Kaku predicts that in 100 years，well become a species that can control the entire sum of a planets energy.Using such power,26thcentury humans will be masters of clean energy technologies.Furthermore，theyll be able to employ planetary (行星的) energy in order to control global climate.Physicist Freeman Dyson，on the other hand，thinks this would occur within roughly 200 years.What other technologies will shape the world of the 26th century？Author Adrian Berry believes the average human life span will reach 140 years and that the digital storage of human personalities will enable a kind of computerized immortality (永生)Humans will farm the oceans，travel in starships and live on both moon and Mars while robots explore the outer space.语篇解读本文介绍500年后的地球会发生什么变化。1Travelling back five centuries in time is mentioned to_.Areview historical eventsBintroduce Renaissance Europe to usChelp us leave records for future peopleDlet us

the world including northwest Africa，Europe and the United States.In 1986，President Ronald Reagan announced the rose was Americas national flower.But the choice of the rose did not smell very sweet to many Americans.Contrary to the common thought，it is easy to grow roses if you start with a few suggestions from experts.First，choose a place to plant your roses where they can get sunshine for about six hours on bright days.You can buy potted roses，also known as container roses，or bareroot plants.Each kind has its fans.Some gardeners say potted roses are easier to plant.They say the roots develop better if they start with potted roses.But considering the high cost of transporting roses，others point out that bareroot roses come without soil，so they weigh less to transport.Placing mulch (护根) around rose plants is normally a good idea.Mulch holds water in the soil.When you grow roses，the soil should be moist deep down.To keep it wet，water the roses in the morning.You can avoid problems like black spots that way.Pay attention to the amount of water.Too much water can cause the leaves to become discolored.On these occasions，try temporarily pulling away mulch from the roots.Doing that will help dry the soil.If the soil is very dry，you can add peat (泥煤) to help condition it.If insects attack your roses，you may be able to force them off with just a spray (喷雾) of water.语篇解读如何种植玫瑰花，一起来看下本文吧！5What can we know about the rose in the first paragraph?AIt was liked by all Americans.BIt was made Americas national flower.CMany countries chose it to be their national
