D.当我们下火车的时候,正在下雨
A.首先look和appear是系动词,“看起来,似乎”,是没有进行时的,see翻译不通,故只能选择being作are的表语,构成主系表结构,句意为“孩子们现在很安静,我想知道他们在做什么.”
D.我很抱歉好久没写了,但是我最近一直很忙.故用完成时表示过去的动作延续到现在.
B.我不认为她是心烦意乱的,但是我会去看她,以防她真的心烦意乱.in case引导条件状语从句,主将从现,又由于前面是be动词构成的主系表结构,故也应该用is.
D.如果她是你的话,她会学习的.if引导虚拟语气,与现在事实相反,从句谓语用过去式,be动词用were.
A.他们看着她长大,因此强调的是成长的过程,而非正在长的动作,因此用see sb.do sth.的句型.
A.by“等到……时候”,要么用过去完成时,要么用将来完成时,根据选项,只能选择A将来完成时.
A.被看到正在做某事,非谓语：see sb doing sth
B.Peter来了,直到昨晚我才知道他要来.过去进行时表示过去将来时.
C.forget to do sth忘记要做某事,根据题意,忘记关灯,故选C
