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.
69. Why did the scientists analyze the laughter made by tickling human babies and apes?
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.
D. To find out the differences between humans and apes.
70. Based on Paragraph 3 we can know that researchers measured the features in the sound to ________.
A. find out ape sounds that hadn’t been realized before
B. find out relations among primates’ laughter
C. see what a family tree from each species looks like
D. make a report online in the journal Current Biology
71. What can be inferred from the last paragraph?
A. Panksepp spoke highly of the new research.
B. Rat laughter is likely to be related to ape laughter.
C. Robert Provine provided some new clues for the researchers.
D. Humans don’t enjoy listening to ape laughter.
72. What would be the best title for the passage?

There’s no doubt that one of the greatest human achievements is the exploration of the space. Ever since astronaut Yuri Gagarin became the first person to be sent into the orbit around the moon in 1961, scientists have been pushing the boundaries further and further. But until now the exploration into the unknown has been dominated (主导) by men.
Of course, in the past, women were also included in the space projects and played an active role on the ground and behind the scenes. For example, they worked as seamstresses (女裁缝师), sewing vital spaceflight components. In fact, many of NASA’s key works would never have been possible without them. Recently Hollywood produced a movie called Hidden Figures to focus on a group of American female mathematicians, especially the black women, who helped NASA send the first American into space. But this was not women’s only contribution. Back in 1963, Soviet astronaut Valentina Tereshkova became the first woman to be sent into space. However, after that, space flight programs were slow to employ women. In the USA. NASA didn’t accept applications from women to become astronauts until 1978.
But attitudes have changed and leading officials at NASA say that the first person to set foot on Mars should be a woman. The space agency aims to have a sex-balanced workforce but can only achieve that if equal numbers of men and women are trained for science and technology jobs. As Allison McIntryre told the BBC, “My director is a woman. We have female astronauts. We haven’t put a woman on the moon yet. And I think that perhaps the first person to step on Mars should be a woman.”
1.What did Yuri Gagarin do in 1961?
A.He landed on the moon in success.
B.He discovered many new boundaries.
C.He led scientists to explore the moon.
D.He made the first journey into the space.
2.Why does the author mention the film Hidden Figures?
A.To show women are the true heroes of NASA’s first launch.
B.To stress that black people have won equal rights in NASA.
C.To prove women can do as well as men in NASA’ projects.
D.To present women’s contributions to NASA’s space programs.
3.What is Allison McIntryre’s attitude toward women astronauts?
A.Uncaring. B.Disapproving.
C.Supportive. D.Disappointed.
4.What is the best title for the text?
A.Will the First Person to Step on Mars Be a Woman?
B.Great Achievements Have Been Made in Space Exploration?
C.Why Men Played an Important Role in Exploring the Unknown?
D.Men and Women Have Made Equal Contributions to NASA’s Projects?

(Reuters) — A group of Chinese scientists and explorers are looking for international help to organize a new search for the country’s answer to Bigfoot, known locally as the “Yeren”, or “wild man”.
Over the years, more than 400 people have said they saw the half-man, half-ape (半猿) Yeren in a remote, mountainous area of the central province of Hubei, state news agency Xinhua said on Saturday.
Expeditions (探险) in the 1970s and 1980s found hair, a footprint, and a sleeping nest suspected(怀疑) of belonging to the Yeren, but there has been no conclusive proof (确凿的证据), the report added.
Witnesses(目击者) describe a creature that walks upright and is more than 2 meters tall with grey, red or black hair all over its body, Xinhua said.
Now the Hubei Wild Man Research Association is looking for volunteers from around the world to join them on another expedition to look for the Yeren.
“We want the team members to be devoted, as there will be a lot of hard work in the process,” Luo Baosheng, vice president of the group, told Xinhua.
But the team will have to come up with about 10 million yuan ($1.50 million) first, and is talking to companies and other bodies to secure the money, so there is no timetable yet for when they may start, the report added.
China is no stranger to crypto zoology. There are many tales about mysterious, monster-like creatures in remote parts of the country. For example, Tibetans have long talked about the existence of the Yeti (喜马拉雅雪人), or “Abominable Snowman”, in the high mountains of their snowy homeland.
1.What the volunteers for this expedition need most is _____.
A. experience B. enthusiasm
C. confidence D. devotion
2.The timetable for starting the trip depends on _____.
A. the number of explorers
B. government’s support
C. the money
D. local people’s guiding
3.According to the text, the underlined word “crypto zoology” in the last paragraph probably refers to _____.
A. the study of mysterious animals
B. the study of human beings
C. dangerous expeditions
D. tourism industry
4.What would be the best title for this text?
A. Volunteers for an expedition needed
B. Scientists to look for China’s Bigfoot
C. International cooperation in finding wild animals
D. Yeren appeared in Hubei again
