1 it follows that by replacing old bulbs as they bum out with the new kind of bulb.
这句的基本意思我明白 但是如果分析句型结构就不太懂了,比如 follow 后面的that是什么成分呢? 还有这句的宾语是啥?混乱Ing
2 they will be produced in large enough quantities to be offered at prices comparable to those of conventional bulb.
这句也是,要怎么正确翻译呢?为啥一会quantities 一会price 它到底在对比啥?
十分感谢各位了!
