ttxhhUID: 2155643

两道2001.10 的改错题
1.(Different fourteen) crops (were being grown) 8600 years (ago) by somoe of the world's earliest ( farmers).
选a， 但是我想问一下were being grown 是什么用法啊？又是什么意思呢？
2.With little (nor )no mass and (no_ electric charge, neutrinos can penetrate a solid object such  the Earth ( as) if it ( were_ not there.
选a，但是如何改呢？另外这里little ...no mass是什么用法，又怎么翻译呢？

期待回复   谢谢哈！！
