[討論] 一個 NYT 的句子,結構和句意

[dibert8]

在 New York Times (China Confirms Protests by Uighur Muslims, April 3, 2008) 看到這一句.
Ethnic groups Beijing has sought to pacify with economic development programs and suppress with a heavy police presence appear to be using the coming Olympic Games, to be held in Beijing in August, as an opportunity to press their grievances and attract international attention.

1. 我對句子結構的理解是 Ethnic groups Beijing has sought to pacify... and suppress... appear to be... => 兩個動詞?
2. Ethnic groups Beijing 看起來不像專有名詞(應該全部大寫),動詞卻用單數 (has)?
3. to be using 在 GMAT 大概不會對了.
4. an opportunity to press their grievances and attract international attention 壓抑抱怨再引起國際關注,說誰?
5. appear 的主詞是哪個?
看不懂在講啥,是不是有人可以分析指點一下呢?

[Huang Hsin-Yi]

我好像看懂了

Ethnic groups Beijing has sought to pacify with economic development programs and suppress with a heavy police presence appear to be using the coming Olympic Games, to be held in Beijing in August, as an opportunity to press their grievances and attract international attention.

北京尋求以經濟活動平緩及武力鎮壓的民族團體,似乎將來臨的奧林匹克, 8月在北京舉行 ,看成是一個機會來引爆他們的不滿和引起國際注意

喔!原來省了一個關代受格.
Ethnic groups {(that) Beijing has sought to pacify... and suppress...} appear to be using the coming Olympic Games, ..., as an opportunity to press their grievances and attract international attention.

感謝!
