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.
1.The underlined word “housed” in Paragraph 4 probably means “_________”.
A.raised B.saved C.discovered D.hunted
2.Which one plays a part in whether dolphin whistles can be heard over a distance?
A.The dolphin’s identity.
B.The water temperature
C.The whistle frequency.
D.The dolphin’s age.
3.When do dolphins copy the signature whistles of loved ones?
A.When there is a fight.
B.When their keeper comes.
C.When they are apart.
D.When they are hungry.
4.The passage probably is taken from______
A.A magazine about scientific advances.
B.A website about various animals.
C.A report on animal acoustics.
D.An essay about the relationship between humans and animals.

高三英语单项填空中等难度题查看答案及解析
You must have been troubled by when to say “I love you” because it is one of the greatest puzzles in our life.
What if you say it first and your partner doesn’t love you back? Or if they do say it but you don’t feel they mean it? Being the first to declare your love can be nerve racking(紧张)and risky and can leave you feeling as vulnerable as a turtle with no shell. But is the person who says it first really in a position of weakness? Doesn’t it pay to hold back, play it cool and wait until the other half has shown their hand fast?
A really good relationship should be about “being fair and being equal,” says psychologist Sidney Crown. “But love is seldom equal.” All relationships go through power struggles but, he says, if a love imbalance continues for years, the rot will set in. “That feeling of ‘I’ve always loved you more’ may be subverted(颠覆,破坏) for a time, but it never goes away completely and it often emerges in squabbling(大声争吵).” In love, at least, the silent, withholding type is not always the most powerful. “The strongest one in a relationship is often the person who feels confident enough to talk about their feelings,” says educational psychologist Ingrid Collins. Psychosexual therapist Paula Hall agrees. “The one with the upper hand is often the person who takes the initiative. In fact, the person who says ‘I love you’ first may also be the one who says ‘I’ m bored with you’ first.” Hall believes that much depends on how “I love you” is said and the motivation of the person saying it. “Is it said when they’re drunk? Is it said before their partner files off on holiday, and what it really means is ‘Please don’ t be unfaithful to me’ ?” By saying ‘I love you’, they are really saying ‘Do you love me?’ If so, wouldn’t it just be more honest to say that. Collins agrees that intention is everything. “It’s not what is said, but how it’s said. What it comes down to is the sincerity of the speaker.”
1. What is the main idea of this passage?
A. The importance of “I love you”
B. The meaning of “I love you”
C. The time of saying “I love you”
D. The place of saying “I love you”
2. In the first sentence the author means that _________.
A. it is easy to say “I love you”
B. it is hard to say “I love you”
C. we have many troubles in our life
D. people usually do not know when to say “I love you”
3. According to the expert, a good relationship should be _______.
A. fair and equal B. fair and kind
C. powerful and equal D. confident and fair
4. In the third paragraph, the phrase “with the upper hand” means _________.
A. being low in spirit B. having only one hand
C. being active D. being passive
