求专业人士进：
是have been increased 还是have increased?两种用法我都看到过,是都可以用无区别还是有区别并且分不同的情况使用?
The production of grain has been increased by four times this year.为什么这里用have been increased?

这个有been的是被动式,要看你前面的这个主语是否能自动增长,这个要仔细体会的,
1.As bear's numbers have increased, conflicts with local people have also,
2.As temperature have increased in recent decades,
这两个都是自动增长没有被增长的意思.

求专业人士进：一个简单的英语问题是have been increased 还是have increased?两种用法我请翻译Executives have been given increased authority, increased 请问have+agreed与have been+agreed有什么区别,好像两种用法都能在例句里看到. 有没有have doing这个说法?我们都知道现在完成时有have done 和have been done 两种用法, i have （been away/left） my home for three years.两种我都见过!left为 They have increased our knowledge and have changed the way__ 请问clever的比较级是加more还是直接变成cleverer?我好像两种用法都见过 I have been here是“我来过这里”还是“我在这里” “have been”到底有几种解释? They have increased the price of oil again sales of computers have greatly increased since the beginnin 英语翻译1,今天,我丢一支我很喜欢的钢笔.是用过去时,还是现在完成时,还是都可以.如果用定语从句,那么是 I have 关于population在比较级中的用法,后面应用that还是it,两种情况我都看到过的,怎样区分.还有关于对人口提问的
