题目列表(包括答案和解析)
When scientists set out to explore the roots of human laughter, some apes(类人猿) were just tickled(胳肢)to help. That’s how researchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praised the work, it gives strong evidence that ape laughter and human laughter are related through evolution(进化).
Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate(灵长类动物) roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.
After measuring 11 features in the sound from each species, they tried to find out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.
Panksepp, who studies laughter-like responses in animals but didn’t participate in the new work, called the paper exciting. Panksepp’s own work concludes that even rats produce laughter in response to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.

A. To try to discover if they can make characteristic sounds.
B. To see if they interested in playing.
C. To find out if the laughter of apes and humans is related.

Amazed zoo visitors watch as an orangutan(猩猩) named Bonnie swings along cables way above their heads. She’s not making a great ape escape; she’s taking a “highway” to higher learning.
Bonnie is traveling on the Orangutan Transit System, called the O-Line, at the National Zoo in Washington, D.C. The O-Line stretches from the Great Ape House, where Bonnie lives, to an exhibit called Think Tank. There she and other orangutans participate in a study trying to answer the questions: Do animals think? If so, how?
Think Tank scientists look for clues that an animal is thinking. A baby orangutan following its mother is probably not thinking. But an orangutan using a stick to reach honey in a beehive probably is thinking. It’s figuring out how to obtain a sweet treat.
To learn more about what the orangutans are thinking, Think Tank scientists are teaching orangutans a language of symbols. The apes don’t actually speak. They point to the symbols to show their thoughts.
Each symbol stands for a word. Different categories of the symbols have their own shapes. Food symbols, for example, are rectangles(矩形); object symbols are circles; and verbs are diamonds.
Computers help the orangutans learn the symbolic language. After the apes are shown an apple, for example, their task is to touch the apple symbol on a computer screen. They can do so. All six orangutans have learned a few symbols, but only Azy and Indah have learned eight symbols and can use the computer.
Azy and Indah choose to live at Think Tank. The others commute(往返) from the Great Ape House on the O-Line. All attend Think Tank sessions, though none are made to do so. “They’re eager to learn”, one of the scientists says. “They never turn me down!”
What is the main idea of the passage?
Scientists are doing research on whether animals can think and how they think.
Biologists have found that orangutans are more intelligent than other animals.
Orangutans at the National Zoo can be taught to communicate with humans easily.
Animals are being taught by scientists to speak to one another at the National Zoo.
The Orangutan Transit System refers to _____.
a way that can teach animals to learn things and communicate quickly
a place for various animals in the National Zoo to participate in the study
a walkway for the orangutans to travel to different sections of the zoo
a line for the orangutans to travel between the Great Ape House and the Think Tank
According to the passage, scientists use a system of symbols to help _____.
find out which orangutan can learn the symbolic language fast
attract all the orangutans to live together at Think Tank
communicate with the orangutans and understand them better
understand whether animals can learn a language and express themselves by using it
It can be inferred from the passage that _____.
a baby orangutan has his own intention though following his mother
many animals in the wild can learn symbolic languages to express their thoughts
the cleverer the animals are, the more knowledge they would like to learn
orangutans can form mental images in their minds when they see objects
ADDIS ABABA, Ethiopia – One of the world’s most famous fossils (化石) – the 3.2 million-year-old Lucy skeleton (骨骼) unearthed in Ethiopia in 1974 – will go on an exhibition tour abroad for the first time in the United States, officials said Tuesday.
Even the Ethiopian public has only seen Lucy twice. The Lucy on exhibition at the Ethiopian National Museum in the capital, Addis Ababa, is a replica while the real remains are usually locked in a secret storeroom. A team from the Museum of National Science in Houston, Texas, spent four years discussing with the Ethiopians for the U.S. tour, which will start in Houston next September.
“Ethiopia’s rich culture of both the past and today, is one of the best kept secrets in the world,” said Joel Bartsch, director of the Houston museum.
The six-year tour will also go to Washington, New York, Denver and Chicago. Officials said six other U.S. cities may be on the tour. But they said plans had not been worked out.
Travelling with Lucy will be 190 other fossils.
Lucy, her name taken from a Beatles song that played in a camp the night of her discovery, is part of the skeleton of what was once a 3-foot-tall ape-man (猿人).
【小题1】The author writes this text mainly to ___ .
A.introduce a few U.S. museums |
B.describe some research work |
C.discuss the value of an ape-man |
D.report a coming event |
A.A painting of the skeleton. |
B.A photograph of Lucy |
C.A copy of the skeleton. |
D.A written record of Lucy. |
A.Four. | B.Five. | C.Six. | D.Eleven. |
A.An ape-man. | B.A song. | C.A singer. | D.A camp. |
Can Apes Really Learn To “Talk”
Who are Sarah, Washoe, Koko, and Sherman? They are chimpanzees or gorillas who some scientists claim have learned how to “talk” to humans. In the past several years people have been astonished by reports that they communicate with humans. For example, Koko, a female gorilla, is said to understand and use hundreds of words. Koko, says her trainer, Francine Patterson, can carry on conversations in sign language about her feelings and plans.
Researcher Talks Back
Recently a Columbia University scientist caused an argument by challenging the conclusion that apes can in fact use language. The scientist, Dr. Herbert Terrace, thinks that the animals do not use language the way humans do. Dr. Terrace has caused such strong feelings among scientists studying ape language. Here let’s listen to an imaginary conversation between Washoe, the first chimp to learn sign language, and Koko, the gorilla.
Apes Are Talking
Koko: Did you hear what Dr. Terrace said about us? He claims we cannot create our own sentences. Instead, he says, we react to clues accidentally given by our trainer. He says we are like the famous horse Clever Hans. Hans was supposed to be able to solve arithmetic problems and then stamp out the answers with his hoof(蹄子).
If the horse was asked what two plus two was, he would stamp four times. Although the trainer did not realized it, says Dr. Terrace, the horse was picking up clues from the trainer as to when to stop stamping.
Washoe: I disagree with Dr. Terrace. My trainer, Dr. R. Allen Gardner and his wife, Beatrice, have seen me talking in sign language to other chimps.
Koko: I heard that Dr. Terrace became unimpressed with ape language after studying a chimp named Nim. Dr. Terrace found that Nim usually made signs only after being prompted (提示) by his trainer. Yet when children learn a language, they start using many words on their own. Nim usually did not do this. Even when Nim did use additional signs, he did not add any new information. The signs (words) were repeated over and over again.
Washoe: My trainer says that Nim wasn’t given much of a chance to act on his own. He had so many different trainers, he became confused. That is not the best way to get chimps to communicate.
Koko: I’ll never understand humans. But the big question is: Can we really use language?
Koko and Washoe (together): We’ll never tell.
How do scientists who study ape language respond to Dr. Herbert Terrace’ idea according to the 2nd part?
A. Enthusiastic. B. Confused. C. Angry. D. Sympathetic.
Which of the following is a match according to the passage?
A. Dr. Herbert Terrace and Koko. B. Dr. R. Allen Garners and Washoe.
C. Clever Hans and Sherman. D. Francine Patterson and Nim.
Dr. Herbert Terrace suspects that _________.
A. Nim added new information while using additional signs
B. Clever Hans picked up clues accidentally given by its trainer
C. Washoe didn’t pick up any clues from its trainer when talking
D. when a child learns a language, he starts using many words on his own
Which of the following is a fact according to the passage?
A. Nim had more than one trainer.
B. Apes can’t create their own language.
C. The apes are supposed to form sentences.
D. Clever Hans is supposed to solve math problems.
