问下考研英语阅读中一句话的理解
1、这句话的主干是It means recognizing how important they can be.how important they can be是从句，做recognizing的宾语，所以是宾语从句。而 recognizing how important they can be是动名词短语作mean的宾语。
2、save的基本意思是采取措施把人或动物从险境中解救出来或使其“脱离危险，免受损失”，可指从危险、灾难、困难、错误中救起某人或拯救某人的性命，也可指人储存金钱、食物、节省时间(以备自救)等，有时还可指人“保全面子、名声”等。Children should learn to save.孩子们应学会储蓄。
3、综述如下：原句是“In the general population today，at this genetic，environmental level，we＇ve pretty much gone as far as we can go”。
