Dolphins call out the specific names of loved ones when they become separated, a study finds. Other than humans, they are the only animals known to do this, according to the study. The big difference with dolphins is that these communications consist of whistles（鸣叫）, not words.
Earlier research found that dolphins have a “signature whistle” that would be somewhat like human shouting, “Hey everybody! I’m an adult healthy male named George, and I mean you no harm. ”
The new finding is that dolphins also say the names of certain other dolphins. “Animals produced copies of the same sound when they were separated from a close partner. This supports our belief that dolphins copy another animal’s signature whistle when they want to reunite with that animal,” Stephanie King, who led the study, says.
King and her colleagues collected acoustic（声音的）data from wild dolphins around Sarasota Bay, Florida, from 1984 to 2009. The researchers also studied four adult male dolphins housed at the Seas Aquarium, also in Florida.
Those males are adults that keepers named Calvin, Khyber, Malabar and Ranier, all of whom, as well as all of the wild ones, developed their own signature whistles that served as names in communication with other dolphins.
“A dolphin uses its signature whistle to broadcast its identity and announce its presence. The signature whistles allow animals to identify one another over long distances and allow animals to recognize one another and to join up with each other,” King explains. “Dolphin whistles can be heard up to 20km away, depending on water depth and whistle frequency（频率）.”
The researchers said dolphins copy the signature whistles of loved ones, such as a mother, when the two are separated. These “names” are always used in positive situations, and are only directed toward loved ones.
While researchers are often unwilling to apply the word language to non-human communications, dolphins clearly have a very complex communication system.The underlined word “housed” in Paragraph 4 probably means “_________”.
| A．raised | B．saved |
| C．discovered | D．hunted |

Announcers on China Central Television (CCTV) will need to do some fast talking to replace the popular English acronyms(首字母缩略词) they’re now forbidden to use. Shanghai Daily reports that “anchors at China Central Television [CCTV] have been banned from saying the English acronyms NBA, CBA, GDP, and the like in their programs
.”
The replacement for those handy acronyms? Chinese presenters must use the full Chinese name, standardized by the State Administration of Radio, Film and Television.
Although CCTV (oops, we mean China Central Television) presenters must already have a score of at least 94 in their government-rated oral Mandarin proficiency exam（普通话等级考试）, saying the full name of organizations like the CBA or WTO ― 10 and 6 charac
ter’s long separately ― is sure to challenge even the most skillful anchors. CCTV sports anchor Sun Zhengping tells Shanghai Daily, “A full Chinese explanation of the English acronyms must be followed if my tongue slips. It is a little trouble but a necessary one because not every audience member can understand the acronyms.”
Although the government isn’t giving any official explanation for the shift, it is believed to have to do with a proposal (提案) by Huang Youyi, director of the China International Publishing Group, at March’s NPC meeting. In his sp
eech, Huang said, “With more and more publications mixing Chinese with English, measures and regulations should be adopted to avoid English invading Chinese. If we don’t pay attention and don’t take measures to stop the expansion of mixing Chinese with English, Chinese won’t be a pure language in a couple of years.”
Although China is far from the first country to take measures to protect local languages (the French and Québécois beat them to it by a long way), acronyms are more about saving time than they are about corrupting a language, we would think. Good luck to the CCTV anchors.

| A．speak as slowly as they like | B．mix English into Chinese |
| C．use shortened Chinese expressions | D．have so much time for their program |
