英语摘自某网站，怎么表明？

目前美国学术界通行的做法是在引文后以圆括弧形式注明引文作者及出处。现针对文中引述的不同情况,将部分规范格式分述如下。
1.若引文不足三行,则可将引文有机地融合在论文中。如:
The divorce of Arnold's personal desire from his inheritance results in “the familiar picture of Victorian man alone in an alien universe”(Roper9).
这里,圆括弧中的Roper为引文作者的姓(不必注出全名)；阿拉伯数字为引文出处的页码(不要写成p.9)；作者姓与页码之间需空一格,但不需任何标点符号；句号应置于第二个圆括弧后。
2.被引述的文字如果超过三行,则应将引文与论文文字分开,如下例所示:
Whitman has proved himself an eminent democratic representative and precursor, and his “Democratic Vistas”
is an admirable and characteristic
diatribe. And if one is sorry that in it
Whitman is unable to conceive the
extreme crises of society, one is certain
that no society would be tolerable whoses
citizens could not find 刷新ment in its
buoyant democratic idealism.(Chase 165)
这里的格式有两点要加以注意。一是引文各行英语论文的左边第一个字母十个空格,即应从第十一格打起；二是引文不需加引号,末尾的句号应标在最后一个词后。
3.如需在引文中插注,对某些词语加以解释,则要使用方括号(不可用圆括弧)。如:
Dr.Beaman points out that“he [Charles Darw in] has been an
