Big tall threatening storm clouds are made of water droplets, and even though water is best at reflecting blue light, it can still reflect green pretty well, much better than reds and oranges, so under just the right conditions, the water in and around a cloud can bounce the green light hidden in the sunset right into our eyes making the sky look green.故選D。）可知，大學(xué)畢業(yè)生對(duì)回家的態(tài)度是積極的，很高興能夠回家，故選B。 （2）考查詞義猜測(cè)。Not only parents but also children want to be independent.D.They are doubtful about whether they should return.D.s return.C.

Since its foundation it has attracted more than 100, 000 students around the globe from India to Nigeria. The course and others like it, e with a simple idea: there is no need to spend years obtaining a PhD in order to practise deep learning. Creating software that learns can be taught as a craft, not as a high intellectual pursuit to be undertaken only in an ivory tower.
