高中英语两道选择题___________,I lost heart in English learning, but my teacher often said to me,"keep on working hard;you will succeed_________"A At a time;in timeB At one time;on timeC At a time;on timeDAt one time;in time The bank is repor
At one time是一度,从前的意思,这里作一度讲,At a time是每次的意思,in time有及时,最终的意思,这里作最终讲.
be reported to do 为固定用法意为“被报道……”,由此可以排除A,B; to have been robbed 是动词不定式的完成形式,说明不定式的行为发生在谓语动作之前.

1.at one time意思是“一度”，要求句子用一般过去时，所以谓语动词lost heart（失去信心，气馁），是关键词。
in time意思是“及时；迟早, 最后”
又如：In time you'll forget him.你迟早会忘了他的。
整个句子的意思是：一度我对英语学习失去了信心，但是老师对我说“继续努力，早晚你会成功的。”
2. 这是固定句型：Sb/...

全部展开

1.at one time意思是“一度”，要求句子用一般过去时，所以谓语动词lost heart（失去信心，气馁），是关键词。
in time意思是“及时；迟早, 最后”
又如：In time you'll forget him.你迟早会忘了他的。
整个句子的意思是：一度我对英语学习失去了信心，但是老师对我说“继续努力，早晚你会成功的。”
2. 这是固定句型：Sb/Sth. is reported/said...to do/to have done/ to be doing
据说/据报道某人/某物做...
注意不定式的时态，完成时表示动作已经发生。而本题意思是银行已经被抢劫，所以用完成时的被动语态：to have been robbed

收起

d at one time 一度，曾经 in time 及时地赶上
The bank is reported to have been robbed in broad daylight yesterday 把地点状语拿走就是这样。 c 是不定式的完成被动形式

其实很简单的，首先at one time 的意思是曾经的意思所以第一空就OK L了;IN time 是及时的意思说以就是D

1 At one time 过去一度，曾经;at a time一次，某时。 in time 最终；on time 按时，准时。
2 应该选B，你的答案有误。be reported doing,被报道做某事，如选C, 结构正确，但意思就是被公布做某事，不符。
希望你能查看牛津词典验证，以免被误导。
