专题限时训练(三十八) [科普知识型阅读理解(一)]
(限时：25分钟) (一)
pet owners start to look like their animals, and vice versa. Now comes the terrifying news that cats look up to their owners as role models and copy their behaviour.
Next time you reach for your fridge, think twice. If your kitty is watching, she is likely to overeat as well.
What is your cat's IQ?
In a new study from the University of Messina, it turns out that indoor cats who live closely to their owners “mirror” the lives of their caregivers. They sleep at the same time, eat at the same time, and can even become more or less social depending on the behaviour of their owners.
揅ats are intelligent animals with a long memory, t”Jane Brunt, the executive director of the Catalyst Council, told Discovery News. 揟hey watch and learn from us, anoting the patterns of our actions, knowing where their food is kept and what time to expect to be fed, how to open the cupboard door that's been improperly closed, and where their feeding and
toileting areas are.”Because cats copy our habits, if you spend a lot of time raiding(搜刮)the fridge, your cat will return to its food bowl for that midnight snack, too. According to the study, this explains why “human and cat overweight rates often seem to match”．So, if you feel guilty about leaving your precious kitty at home while you go to work, now you can feel even worse：you are making your cat fat!
There's no word if drinking green tea and making sure you go to yoga will benefit your cat, but based on the study, it sounds like sticking to a healthy eating and sleeping schedule is best for both of you.
There's a lot we can learn from our cats in return. “When they sit on our laps softly purring with rhythmic breathing and half-closed eyes, the sense of peace and calm that comes over
us is like a private lesson in inner meditation，”Brunt said. Sure. But cats don't have to sit in rush hour traffic for an hour a day or worry about their in-laws. They're probably pretty
good at remaining calm.according to science, even though we assume that cats are not close to us all these years, it turns out they are in fact learning from us and looking up to us. Scary, huh?

B．Humans can learn from cats in some way. C．Cats are smart and have a long memory.
D．Green tea and yoga can benefit cats.
2．What does the underlined word “this” in Paragraph 5 refer to? A．Humans' keeping searching the fridge. B．Cats' going to their owners for food.
C．Cats' copying humans' habit of looking for food. D．Humans' leaving cats home while working. 3．What can we learn from our cats? A．To remain calm. B．To be able to copy. C．To stay proud.

(二) of mental and physical diseases, it is still a serious scientific subject that researchers are trying to figure out.
揕aughter above all else is a social thingi，” says Baltimore neuroscientist, Robert Provine, who has studied laughter for decades. “All laughter groups laugh ‘ha-ha-ha’ basically the same way. Whether you speak Mandarin, French or English, everyone will understand laughter. There is a pattern generator(发生器) in our brain that produces this sound.”bies laugh long before they speak. No one teaches them how to laugh. They just do. People may laugh at a prank(恶作剧) on April Fools' Day. But surprisingly, only 10 to 15 percent of laughter is the result of someone making a joke. Laughter is mostly about social responses rather than to a joke. Deaf people laugh without hearing and people on cell phones laugh without seeing, showing that laughter isn't dependent on single sense but on social interactions.
And laughter is not just a thing of people. Chimps tickle(挠痒) each other and even laugh when another chimp pretends to tickle them.a Bowling Green University Psychology
professor, studies rats that laugh when he tickles them. It turns out rats love to be tickled—they return again and again to the hands of researchers tickling them.
By studying rats, scientists can figure out what's going on in the brain during laughter.
Northwestern University biomedical engineering professor, Jeffrey Burgdorf has found that laughter in rats produces a chemical that acts as an antidepressant(抗抑郁药). He thinks the same thing probably happens in humans, too. This would give doctors a new chemical target to develop drugs that can fight depression.
Even so, laughter itself has not been proved to be the best medicine, experts say. Margaret Stuber, a professor at University of California, studied whether laugher helped patients. She found that distraction(分心) and mood improvement helped, but she could not find a benefit of laughter alone.
“No study has shown that laughter produces a direct health benefit，” Provine said, largely
because it's hard to separate laughter from just feeling good. But he thinks it doesn't really matter, “Isn't the fact that laughter feels good when you do it enough？” important finding of Robert Provine's research is that ________．laughter makes a person feel good B．laughter depends on different senses C．laughter is a quality people are born with
D．laughter is a social response shared by all creatures
2．According to the passage, scientists studied rats in order to find ________．if they can laugh
B．if they like laughing
C．what laughter in rats produces D．how rats react while being tickled 3．What can we learn from the passage?
A．Patients will recover if they laugh enough.
B．Laughter is a means of communication as well as a language.
C．A new medicine has been developed based on the laughter research.
D．Scientists can know what is happening in a human brain when he laughs. 4．Which of the following shows the structure of the passage? A. B. C. D.

(三)rly 20th century, but Hollywood brought the technology back in 2020. Many thought it was just a trick to make more money. But then came Avatar, the first must-see movie in 3D.
But since Avatar, 3D cinema has struggled.
In_2020,_several_3D_movies_bombed_at_the_box_office. And by late 2020, some people said the technology was dead. Of course, that wasn't the first time Hollywood had struggled with new technology. Although sound was added to movies in the late 1920s, it took audiences time to get used to the new technology. But in the end, sound and colour became the
standard. James Cameron, director of Avatar, thinks we're going through the same process with 3D.
Some say cinemas are charging too much for 3D movies. In the US, seeing a 3D movie can cost up to $7.5 more than seeing it in 2D.Also, a recent study at California State University finds audiences don't actually enjoy movies in 3D any more than in 2D.Walter Murch, a
famous movie editor, wrote in 2020 that human beings have no ability to process 3D images. Watching a 3D movie confuses our brain and this is why some people get headaches.
But James Cameron disagrees. In fact, he recently predicted that in five years all movies will be in 3D.And there are signs that 3D is fighting back. More 3D movies were put on the market in 2020 than ever before. The Lion King 3D recently made over US $150 million at the box office, and Cameron's Titanic 3D made even more.
Who knows what the future holds for 3D? Steven Spielberg recently said, “I'm hoping 3D gets to a point where people notice it. Because then it just becomes another tool and helps tell a story.”
1．The underlined sentence in Paragraph 2 probably means that in 2020, 3D movies________．were not successful B．became popular C．developed quickly D．were of poor quality
2．The example of sound and colour is used mainly to show that________．Hollywood tends to absorb what is new
B．3D technology takes time to be accepted C．Hollywood struggles with new technology D．high technology helps to make better movies
3．In Walter Murch's opinion, 3D movies________．bring moviemakers great profits B．are more expensive than 2D movies C．do great harm to people's health D．are unsuitable for people to watch 4．What can we learn from the text? A．Avatar was the first 3D movie. B．3D cinema has existed for years.
C．Titanic 3D has made the most money. D．2020 witnessed the coming of 3D's time.
