强降雨持续 长江部分支流超历史最高水位
<p>截至7月1日，长江流域共有42条河流52站发生超警及以上洪水，主要集中在两湖水系，包括湘江湘潭、资水桃江站在内9站超保证水位，部分支流站水位超历史最高水位。</p><p><span word="Days">Days</span> <span word="of">of</span> <span word="torrential">torrential</span> <span word="rain">rain</span> <span word="in">in</span> <span word="central">central</span> <span word="China">China</span>'<span word="s">s</span> <span word="Hunan">Hunan</span> <span word="province">province</span> <span word="raised">raised</span> <span word="the">the</span> <span word="water">water</span> <span word="level">level</span> <span word="of">of</span> <span word="the">the</span> <span word="Xiangjiang">Xiangjiang</span> <span word="River">River</span>, <span word="a">a</span> <span word="major">major</span> <span word="tributary">tributary</span> <span word="of">of</span> <span word="the">the</span> <span word="Yangtze">Yangtze</span> <span word="River">River</span>, <span word="to">to</span> <span word="exceed">exceed</span> <span word="its">its</span> <span word="record">record</span> <span word="flood">flood</span> <span word="level">level</span> <span word="Sunday">Sunday</span> <span word="morning">morning</span>.</p><p>湖南省连日强降雨，导致长江主要支流湘江水位上升，2日上午已超历史最高水位。</p><p><span word="Already">Already</span> <span word="at">at</span> 3.2 <span word="meters">meters</span> <span word="above">above</span> <span word="the">the</span> <span word="warning">warning</span> <span word="level">level</span>, <span word="the">the</span> <span word="water">water</span> <span word="level">level</span> <span word="is">is</span> <span word="expected">expected</span> <span word="to">to</span> <span word="continue">continue</span> <span word="to">to</span> <span word="rise">rise</span> <span word="as">as</span> <span word="heavy">heavy</span> <span word="rain">rain</span> <span word="is">is</span> <span word="forecast">forecast</span> <span word="for">for</span> <span word="upstream">upstream</span> <span word="regions">regions</span> <span word="over">over</span> <span word="the">the</span> <span word="next">next</span> <span word="few">few</span> <span word="days">days</span>.</p><p>目前，湘江水位已超警戒水位3.2米，未来几天上游地区强降雨继续，水位可能继续上涨。</p><p><span word="Tributary">Tributary</span>指的是<span word="a">a</span> <span word="stream">stream</span> <span word="or">or</span> <span word="river">river</span> <span word="that">that</span> <span word="flows">flows</span> <span word="into">into</span> <span word="a">a</span> <span word="larger">larger</span> <span word="one">one</span>，即“支流”，“<span word="XX">XX</span>江/河的支流”一般都用<span word="a">a</span> <span word="tributary">tributary</span> <span word="of">of</span> ...<span word="River">River</span>表示，比如这里的<span word="a">a</span> <span word="major">major</span> <span word="tributary">tributary</span> <span word="of">of</span> <span word="the">the</span> <span word="Yangtze">Yangtze</span> <span word="River">River</span>或者<span word="a">a</span> <span word="tributary">tributary</span> <span word="of">of</span> <span word="the">the</span> <span word="Amazon">Amazon</span>（亚马逊河的一条支流），等等。因为支流也分大小，所以可以在<span word="tributary">tributary</span>前面添加<span word="major">major</span>来表示某条河流是“主要支流”。</p><p>在水文学上，支流（<span word="tributary">tributary</span>）指汇入另一条河流（或其他水体）而不直接入海的河流。支流所汇入的河流称为干流或主流（<span word="mainstream">mainstream</span>），两河或多河交汇之处称为合流或合流处（<span word="confluence">confluence</span>）。与支流相反的情况称为分流（<span word="distributary">distributary</span>）。</p>
