本文从以下几个角度介绍。

C Achieve success at all costsD.Stick to your dreams.CThe success of many North American crops partly depends on ground beetles,small insectsthat eat pests and weed seeds that could otherwise damage crops.But a new study by researchersin the U.S.and Canada suggests not all of the nearly 2,000 species of ground beetles found inNorth America will survive climate change.Some could decline.And that could have afar-reaching impact on agriculture,forestry,and conservation.By analyzing data on 136 different ground beetle species across continental North America,Puerto Rico and Hawaii,the researchers found that a species'chance of success in a changingclimate depends on several important factors,such as its habitat preference,body size,andwhether it flies,climbs or runs."We found that less mobile,nonflying ground beetles,which are critical pest control agents,are more likely to decline over time in a warmer,dryer climate,"said Tong Qiu,who led thestudy."That means you're going to have more pests that can impact agricultural and forestecosystems."But there is reason for hope,Qiu added,because the analysis also showed thathabitat conservation can lessen these effects and reverse the trends in some areas."We hope conservation biologists will use this information and the online map that we createdto better manage habitats for insects in general.Ground beetles are very beneficial toecosystems,but they're largely invisible to the average person.In this paper we're showing thebroad impacts they have on whole communities in forested and agricultural ecosystems,"saidQiu.The researchers used ground beetle count data from the National Science Foundation'sNational Ecological Observatory Network (NEON)and from 11 previously published studies tomeasure and map the beetles'distribution across North America.Habitat information,such as thelocation of gap s in forest canopies and the density of plants on a forest floor,was obtained byusing NEON's imaging instruments to create detailed three-dimensional images of landscapes.They then entered the data collected into a computer model to simulate (climate changesto study how the insects would respond.28.What does the new study in North America show?A.The survival of ground beetles only depends on its habitatB.Some ground beetles will not survive a climate change.C.Pests could destroy crops.D.Some ground beetles will destroy crops in a warmer climate.29.What does Tong Qiu intend to convey in paragraphs 3 and 4?A.Ground beetles will become less mobile in a warmer climate.B.There is no way to stop the decline of ground beetles.C.Critical pests are more adaptable in a warmer,drier climate.D.The importance of ground beetles should be widely recognized.30.How did the research team carry out the study?5
