1、But today,more and more countries try to establish democratic systems,which enable people of different classes to involve in the management of the nation.
首先systems用复数对吗?因为前面有个countries,其次 enable sb to do sth在这用得对吗?还有其他地方是否有错误请帮忙一并改正
2、people’s welfare should doubtless be the best indication of a nation’s greatness.
doubtless应该用副词还是.应该放哪里比较好,请用语法角度解释下
第一句：
systems 没问题,这里要加-s.
但,involve 不对,要变为：get/be involved in,即：...classes to get/be involved in ...
因为这个动词的用法是：involve sb.in (doing) sth.（使某人牵涉或卷入某事）
第二句：
doubtless改为undoubtedly,通常放在句首.且should be => is,才能表示语气肯定.
整句：Undoubtedly,people's welfare is the best indication of a nation's greatness.
或者：People's welfare is undoubtedly the best indication of...如楼下所说那个改为to be get involved in,,,应该也可以吧？另外那个毫无疑问的那句，还是把整句发上来 吧get involved in 表示动作，be involved in 表示状态，任选一个都行。如果要表达“应该是”，可以用 indisputably （毫无争议地），即：People's welfare should be indisputably the best indication of a nation's greatness.
