For instance,Americans will never forget the hospitality shown to our pilots who were shot down
over your soil during World War II,and cared for by Chinese civilians who risked all that they had by doing so.
例如,在二战期间,在美国国土上,美国人永远都忘不了那些被击落的中国飞行员给过他们的热情救助,以及中国人民不顾一切冒险送上的关爱.
they had是指 all that they had,by doing so 是指care for 这件事...
意思是指 中国人民把它们拥有的一切都冒险不顾了,用来关爱美国人.by doing so是固定的词组吗?by doing sth,这是个固定词组,意思为通过做某事。。。来达到什么目的。。。by doing so ,也可以当做固定词组,就是通过这样做的意思。
