C | 淮河入海水道二期工程是国家重大水利工程，全长162.3千米，在原有一期工程的基础上开展改扩建，全面提升行洪能力的同时，还能通行两千吨级船舶，形成淮河流域高效出海通道。
D | 一批交通基础设施建设加快推进。 While scientists are still to determine whether some extraterrestrial civilization may exist somewhere out there in the universe, one astronomer points out that we apparently don’t have a plan for a yet-hypothetical situation where aliens actually reach out to us.,According to the Daily Star, prominent popular scientist and Australia’s Astronomer at Large Fred Watson pointed out that scientists do have a checklist to establish whether a communication attempt by aliens is genuine, but don’t have a plan for actually establishing contact with them.,“There’s a well-established chain of boxes that need to be ticked and it would go through a lot of analysis to ensure that what you’re talking about is a real phenomenon,” he said. “However, once scientists identified what had happened, it’d then be up to the political leaders of the world to decide what to do about it, and as far as I’m aware, there’s no plan in place.”,Burnout or Homeostasis: Researchers Explain Why Aliens Are Yet to Come Knocking at Earth's Door20 June, 13:15 GMT,He did note, however, that there is a rather “gloomy outlook about there being intelligent life forms” out there in space, with the “overwhelming opinion” being that “microbial life might exist.”,“The common view is we are just a complete freak of nature – intelligent life is so rare and is such an unlikely event," Watson remarked.。
E | 8月20日，陕西西安至安康高铁进入按图试运行阶段。正式通车后，两地铁路运行时间由3小时左右缩短至1小时以内，关中与陕南“一小时经济圈”加速成形。8月20日，在河南周口，平顶山至漯河至周口高铁的控制性工程——郑阜上行联络线特大桥连续梁在40分钟内顺时针旋转25度，实现精准对接，为后续架梁及铺轨施工奠定基础。平漯周高铁建成后，将打通我国西北经中原至长三角的高速客运新通道。在黑龙江哈尔滨，东北地区最大的系杆拱桥——松花江特大桥顺利完成合龙，大桥全长近4700米，将有效缩短哈尔滨县域间往来时间。
F | 不断夯实高质量发展基础。8月20日，吉林洮南20万吨绿色甲醇二期项目启动建设，项目预计2028年投产，建成后可年产20万吨绿色甲醇、1万吨可持续航空燃料。这段时间，甘肃至浙江±800千伏特高压直流输电工程甘肃第四标段实现贯通。该标段横穿秦岭西麓，全长67千米，是全线施工难度最大的区段之一。目前，工程全线导线架设进度已超九成。陇电入浙工程全线总长2370公里，是我国“西电东送”战略的关键骨干能源通道。
G | 预计明年4月投产后，每年可将超过360亿千瓦时的清洁电能从甘肃送往浙江。版权申明：凡注有“”或电头为“”的稿件，均为独家版权所有，未经许可不得转载或镜像；授权转载必须注明来源为“”，并保留“”的电头。 。
