問題詳情

▲閱讀下文,回答第 16−20 題Bumblebees are social insects that form colonies with a single queen. They have roundbodies covered in soft hair, which makes them appear fuzzy. They are important agriculturalpollinators as they are good at fertilizing many types of wild plants. However, new researchusing a massive dataset has found that the insects are far less common than they used to be.In a new paper published in the journal Science, researchers used a complex modeling processto suggest that the dropping number is driven in large part by climate change. It has long beenknown that bumblebees are more adapted to cold weather. Their fuzzy bodies allow them togenerate heat while flying, which often allows them to be the first bees out in the spring.Nevertheless, exactly how vulnerable they are to heat waves still isn’t clear.Bumblebees are also threatened by pesticides or chemicals. Research has shown thatpesticides would significantly reduce growth rate and cut production of new queens by 85%,implying a “considerable negative effect” on wild bumblebee populations throughoutthe developed world. Bumblebees that are affected by pesticides may collect more pollen, butthey need a longer amount of time doing so. Other common factors include habitat destruction,conversion of wilderness into agricultural land, and the release of non-native bees forcommercial use. While several factors clearly contribute to declining bumblebee populations,there is disagreement over whether climate change is the most important factor. Jamie Strange,Chair of the Entomology Department at Ohio State University is concerned thatoveremphasizing climate change will result in neglecting to combat other factors which are “allequally or more impactful on bee populations worldwide.”Nonetheless, there are simple things people can do to help the bees. These includebee-friendly yard practices like avoiding the use of pesticides and planting native flowers thatbumblebees can feed on. In addition, planting flower beds that are continuously in bloom canalso help. Furthermore, creating more parks or planting trees in urban environments—which areoften cooler than surrounding built spaces—could give bumblebees places to shelter from theheat.
