这个at high water在句子作什么成分,为什么要放在这?句子是这样的,There was a salt-marsh that bounded part of the mill-pond,on the edge of which,at high water,we used to stand to fish for minnows.我不明白为什么at high water 这个动词不定式作句子的什么成分Water,food,and electricity were hard to get.动词不定式to get在句中做什么成分? the heat capacity of water is relatively high.这里的is relatively high不是系表结构吧!BE动词后面+ADJ构成系表,那这里的relatively 又是修饰high的!那这个句子怎么分析哦? as在这个句子中的作用?the concentration of heteroactivator will determine whether no effect or activationresults,17 or even if inhibition results (as) documented with some activators at high concentrations. at distance和in the distance有什么区别吗?看这个选择：The high mountain looks beautiful ＿.A at distanceB at a distanceC in distanceD in a distance隔开一段距离与在远处在这个句子里都讲的通啊 请译：Do you want them to be your good friends?问题1：请帮助翻译这个句子：Do you want them to be your good friends?问题2：at和in的用法有这两个句子：He studies in a school.He studies at No.1 High school.在这里,at和i the high building (they are looking at) are big hotel解释一下括号中的词组在本句子中的成分, Water has no smell at all.保持句子原意 Two years ago ,Sally was in a high school.Today,she studies in collage在这个句子里a high为什么要加a不加可不可以 HELL AND HIGH WATER怎么样 Hell And High Water 歌词 children can be instructed in swimming at a very early age.children become expert at holding their breath under water even before they can walk.在第一个句子里,是用in,代表,在什么什么方面,第二个句子里,是用at代表在什么什 不可数名词作主语时后面的谓语动词要用第三人称单数形式么?例如这个句子：Water covers most parts of the earth.如果在这个句子前面加some或者much什么的时候谓语动词的形式又会不会有什么变化呢 为什么在初中是At junior high school 在高中是In senior high school Water is a liquid at room temperature and has a relatively high frozen point.哪里错了 在高空中,in high altitude?at high altitude?哪个正确?
