President Barack Obama nominated (提名) Utah governor Jon Huntsman as ambassador (大使) to China on May 16.

Huntsman, 49, is the son of a Utah multimillionaire (千万富翁). He served as ambassador to Singapore under former president George H.W. Bush. In 2004, he became the governor of Utah and was elected for a second term in 2008.

The governor has strong ties to China: He lived in Taiwan when he was a teenager and speaks fluent Chinese. One of his daughters was adopted (收养) from China. His family also has business ties with China through Huntsman Corp, a chemical company. It has operations (动作) in the country including a factory in Shanghai.

Huntsman’s nomination has been met with praise in both countries.

“Jon Huntsman is a well-regarded politician (政治家) in the US…… his experience as ambassador to Singapore and his knowledge of China, plus his wonderful Chinese language skills singled him out from the large number of candidates,” Dai Min, president of the US-based Center for America-China Partnership (中美合作中心), told China Daily.

Obama appointed Huntsman “in order to seek China’s help and cooperation” on several international and regional issues, said Yuan Peng, professor of American Studies at the China Institute of Contemporary International Relations (中国现代国际关系研究院).

Some people say that President Obama’s decision to name John Huntsman is a well thought out political strategy. Huntsman is a big player in the Republican Party, and a possible presidential candidate for 2012. If he really has joined the Obama administration, he has lost that possibility. Now, when Obama kicks off his re-election campaign, “ambassador” Huntsman won’t be a threat.

64.The nomination of Huntsman won praise on both sides for the following reasons EXCEPT that _________.

A. he has business ties with China

B. he can speak Chinese fluently

C. he is a very experienced politician

D. he knows China very well

65.Which of the following facts about Huntsman is NOT true ?

A. He was once ambassador to Singapore.

B. He was elected governor of Utah twice.

C. He has served two presidents as governor.

D. He spent part of his youth in Taiwan.

66.From the last two paragraphs, we can conclude that ____________.

A. Obama considers China America’s top trade partner.

B. By choosing Huntsman, Obama kills two birds with one stone.

C. Huntsman will probably run for president in 2012.

D. Huntsman will settle several international and regional issues.
