英语翻译
I expected that Tokyo would be quite old but there are very few parts of it which are old in fact at all ,because it was firebombed during the Second World War by the American ,there are one or two temples that survived that but basically it's a city that's been built since 1945.
主要是原文中的这句话看不懂,
there are one or two temples that survived that but basically it's a city that's been built since 1945.
还有这句话实在不明白有什么作用呢 that but basically it's a city
那么也就是说城市重建和前面的寺庙没有太大的联系咯,那怎么这句话还从句套从句呀,这位高手说的有理呀,我也觉得满怪的,that后的句子总归是说明前面的或者比较有联系的，但是突然在that后来个转折，脑子都转不过来了
