请问什么时候用这种句型?When I was walking through the park the other day,I noticed a young kid climbing a tree.I stood watching him for a few minutes,lost in nostalgia,when,out of nowhere,a woman came screaming past me.句中,I was walking 'How I wish I had a car!'这一句用的是什么句型?这种句型怎么用?什么时候用>?Please help me ..I'm waiting for the answer~ 英语翻译采用这种句型 I want to know when we are leavingi want to know when to leave “为”什么时候读wéi什么时候wèi has been received 和has received 这两个句型到底有什么差别?比如说:i have received the MA degree,和 i have been received the MA degree到底区别在哪里?或者说其中一个句型是错误的.还有什么时候用这种句型? 英语句型中什么时候用“I”,什么时候用“I 'm”呢?造句时,我还不大分得清楚~ 是10 minute's walk还是10 minutes' walk还是10 minutes's walk就是这种句型该怎么用呢?那请问什么时候是minute's walk呢？minutes's walk的情形不存在对吧 强调句型有it's ... where/when这种形式吗? 用这种句型造句,要两组～ 什么时候用when I started English when I was four years old句型 我想请问一下,什么时候用I always.什么时候用 I`m always.什么时候用 I was always.同 It -------- five years since he left his motherland.这种句型的题,什么时候用It was,什么时候用It is啊?具体一点,举个例子啊..... 用there be 的句型填I want to see it when _____not so many people. I don't know when I can post the letter.改为同义句I don't know ___ ___ ___the letter.请问这是什么句型?为什么这么填? 什么时候用it is的句型 will be 句型是什么?be什么时候用! this was the place__last year.A.which I visited B.where I visited搞不清什么时候用which什么时候用when
