264. Scientists believe that unlike the males of most species of moth, the male whistling moths of Nambung, Australia, call female moths to them by the use of acoustical signals, but not olfactory ones, and they attract their mates during the day, rather than at night.

Nambung, Australia 在英语中是标准的表示地点的方式:

I live in Los Angeles, California.

The 2008 summer game is in Beijing, China.

作插入语的话, 我觉得应该是: Nambung, in Australia, ...

作同位语的话, logic不通, 两个特定地点怎么可以同等.

请NN们再看看.

找到啦!!! 找不到答案死不瞑目, haha

When both a city's name and that city's state or country's name are mentioned together, the state or country's name is treated as a parenthetical element.

· We visited LACE w:st="on">Hartford, ConnecticutLACE>, last summer.

· LACE w:st="on">Paris, FranceLACE>, is sometimes called "The City of Lights."

When the state becomes a possessive form, this rule is no longer followed:

· LACE w:st="on">Hartford, ConnecticutLACE>'s investment in the insurance industry is well known.

Also, when the state or country's name becomes part of a compound structure, the second comma is dropped:

· Heublein, a Hartford, Connecticut-based company, is moving to another state.

ETS的题中一个不起眼的逗号都有玄机啊!
