They had come home to tell me about the fire in the garage next to Nancy's house. Not only did my feet and voice work now, but my eyes were also in good working order and had no trouble producing tears. We are naturally drawn to friends and colleagues with familiar voices, scientists have found. People prefer those who have a similar accent, intonation and tone of voice to themselves, they discovered.Previous research has focused on how a male or female voice sounds. Men with deeper voices and women with slightly higher voices were thought to sound more attractive, because they suggest a bigger or a smaller body. But the new study, published by a linguistics expert in Canada, suggests there is a more complex mechanism(机制)at play. Dr Molly Babel, from the University of British Columbia in Canada, said, “The voice is an amazingly flexible tool that we use to construct our identity. Very few things in our voices are changeless, so we felt that our preferences had to be about more than a person’ s shape and size.’’

Parts of Western Europe suffered from deadly floods while large areas of the southwestern United States remained locked in a massive drought. One might think that our impressive water management would safeguard society from such catastrophic events. Yet when it comes to water, the past is no longer a good guide for the future and most of the water engineering is unprepared for consequences of increasingly occurring extreme weather. One of the most alarming wake-up calls came from the city of Cape Town, where the water taps of 4 million residents were nearly forced to be shut off after severe drought dried up its reservoir (水库). Appealing as it might be, the solution is not to further build bigger and higher dams (水坝) that often result in more disastrous flooding. Rather, it is to work more with natural processes. The Netherlands avoided major damage from the historic floods in July 2021 thanks to its recently completed project, which gives river room to spread out by redirecting floodwaters into wetlands, lowering parts of the stormy river by more than a foot. Agricultural practices offer another strategy. Scientists have found that boosting organic matter in the soil by 1% can increase the soil’s water-holding capacity by up to 18,000 gallons per acre, creating flexibility to both intense rains and dry periods. This means farmland practices such as the planting of cover crops can not only raise output but improve water management.
