21、Every new parent knows, or learns pretty quickly, that rocking can calm the crying baby when it’s time to take a nap. But the benefits of gentle motion(运动)may extend past the swaddling(襁褓)stage. Because two new studies show that rocking also helps grown-ups, both human and mouse, get a good night’s sleep.
What should be no surprise is that movement can be soothing. Think of how many times you’ve fallen asleep on a train. But can motion really cause a nap, and make for a deeper sleep?
To find out, researchers invited 18 healthy volunteers for a sleepover. “So they came to the lab and they slept one time on normal beds which are motionless. And one night where they got rocked,” said Aurore Perrault, a sleep researcher at the University of Geneva in Switzerland. “And what we find is that when compared to a motionless night, a whole night of rocking sleep has a beneficial effect not only on sleep beginning but also on sleep maintenance, as we saw that they have less micro-awakening during the night.” Subjects who rocked also did better on a memory test the next morning than the stiller sleepers.
In the second study, Knostantinos Kompotis, a postdoctoral fellow at the University of Lausanne, rocked a group of mice. “Whether rocking affects sleep in species other than humans was never before discussed. So the main questions for our study were does rocking affect sleep in mice and what’s the reason?”
Kompotis placed the mouse cages on a platform that moved from side to side. And though mice were rocked four times faster than their human counterparts—a frequency of one back-and-forth per second, or 1Hertz, worked best—the results were strikingly similar. During rocking at 1 Hertz, time spent asleep increased, and mice fell asleep twice as fast as at still condition.
Additional studies could allow the researchers to identify a new target for treating sleep disorders, including insomnia(失眠). Until then, you might think about adding a little swing to your night-time routine.

【3】What can we learn about the mice according to Paragraph 5?
A．Their sleep disorder including insomnia was treated.
B．Their sleeping time increased when rocked at 1 Hertz.
C．When rocked from side to side, they failed to fall asleep.
D．When rocked, they fell asleep four times faster than at still condition.
【4】Which of the following can be the best title for the text?

22、 Hardware in general, and smartphones in particular, have become a huge environmental and health problem in the Global South’s landfill sites(垃圾填埋场).
Electronic waste (e-waste) currently takes up 5 percent of all global waste, and it is set to increase rapidly as more of us own more than one smartphone, laptop and power bank. They end up in places like Agbogbloshie on the outskirts of Ghana’s capital, Accra. It is the biggest e-waste dump in the world, where 10,000 informal workers walk through tons of abandoned goods as part of an informal recycling process. They risk their health searching for the precious metals that are found in abandoned smartphones.
But Agbogbloshie legally should not exist. The Basel Convention, a 1989 treaty, aims to prevent developed nations from unauthorized dumping of e-waste in less developed countries. The e-waste industry, however, circumvents regulation by exporting e-waste labelled as “secondhand goods” to poor countries like Ghana, knowing full well that it is heading for a landfill site.
A recent report found Agbogbloshie contained some of the most dangerous chemicals. This is not surprising: smart phones contain chemicals like mercury(水银), lead and even arsenic(砷). Reportedly, one egg from a free-range chicken in Agbogbloshie contained a certain chemical which can cause cancer and damage the immune system at a level that’s about 220 times greater than a limit set by the European Food Safety Authority (EFSA). Most worryingly, these poisonous chemicals are free to pollute the broader soil and water system. This should concern us all, since some of Ghana’s top exports are cocoa and nuts.
Some governments have started to take responsibility for their consumers’ waste. For example, Germany has started a project that includes a sustainable recycling system at Agbogbloshie, along with a health clinic for workers. However, governments cannot solve the problem alone, as there is an almost limitless consumer demand for hardware, especially when governments’ green policies are focused on issues like climate change.
Only the manufacturers can fix this. A more economically sustainable and politically possible solution is through encouraging hardware manufacturers to make the repair, reuse and recycling of hardware profitable, or at least cost-neutral.
【1】What can we infer from Paragraph 2?
A.Electronic waste requires more landfill sites.
B.Electronic waste is too complex to get fully recycled.
C.Electronic products need to be improved immediately.
D.Electronic pollution is a burning question in Agbogbloshie.
【2】What does the underlined word “circumvents” in Paragraph 3 mean?
A.Relaxes. B.Abolishes. C.Avoids. D.Tightens.
【3】What should be the biggest concern according to the text?
A.The violation of EFSA’s standards. B.The threat of polluted food worldwide.
C.The lack of diversity in Ghana’s exports. D.The damage to chicken’s immune system.
【4】What does the author think is the best solution to the e-waste problem?
A.Letting governments take on the main responsibility.
B.Reducing customers’ demands for electronic products.
C.Governments adjusting their green policies about e-waste.
D.Manufacturers’ developing a sustainable hardware economy.
23、An electric signal can trick a monkey’s brain into believing the animal’s finger has been touched.
Touch something, and your brain knows. The hand sends signals to the brain to announce contact was made. But that feeling of touch may not require making actual contact, tests on monkeys now show. Zapping brain cells can fool the animal into thinking its finger has touched something.
A person who has lost a limb or become paralyzed may need an artificial limb to complete everyday tasks. But such patients may not truly feel any objects they hold. The new findings point toward one day creating a sense of touch in those who use such artificial limbs. Psychologist Sliman Bensmaia of University of Chicago worked on the new tests. His team’s findings appeared on October 14 in the Proceedings of the National Academy of Sciences of the United States of America.
The sense of touch is crucial to everyday tasks: People without it may have difficulty cracking an egg, lifting a cup or even turning a doorknob. That’s why restoring it is a major goal for designers of artificial limbs.
In their new study, Bensmaia and his co-workers worked with rhesus monkeys (恒河猴). The scientists implanted electrodes (电极)--- small devices that can detect and relay an electrical signal—into the animals’ brains. The scientists used the electrode data to identify which neurons had become active. Then the scientists used the implanted electrodes to zap those same neurons. And the monkeys reacted as though their fingers had been touched. In fact, they hadn’t.
The monkeys couldn’t use words to tell the scientists what they had felt. Instead, they communicated by looking in a particular direction—just as when they had really been touched.
The new findings show how touch-sensitive devices could be built. The new study also offers “ a nice clear pathway” for figuring out how to restore a sense of touch to an amputee(被截肢者) or someone with a injury of spinal cord.
The study shows how artificial limbs might be connected to the brain so that a person can “feel” with such a prosthesis (假肢). But such a supersensory device doesn’t exist yet and scientists have a lot of work to do before people will benefit from it. Researchers must first figure out whether the electrodes would work in people in the same way they do in monkeys.
“ I think the foundation is laid for human trials,” Bensmaia said.

24、 Wildfires have recently ruined regions across the world, and their severity is increasing. Hoping to reduce harm, researchers led by Yapei Wang, a chemist at Renmin University of China, say they have developed an inexpensive device to detect such fires earlier and with less effort.
Current detection methods rely heavily on human watchfulness, which can delay an effective response. Most wildfires are reported by the general public, and other warnings come from routine foot patrols (巡逻队) and watchtower observers. Passing planes and satellites also occasionally spot something, but “the fire first appears on the ground,” Wang says. “When you see the fire from the sky, it is too late.”
The team says its new device can be placed near tree trunks’ bases and send a wireless signal to a nearby receiver if there is an unusual temperature increase. The key is molten salts (熔盐) liquids: a sudden temperature change causes electrons (电子) to travel within the liquids, creating electrical energy that causes electrodes to send the signal. The team printed the substances onto ordinary paper to create a sensor.
Jessica McCarty, a geographer at Miami University, who was not involved in the study, says places where wildland and city meet could potentially benefit from such a device. She says, “When a fire breaks out, the homeowner will know before the fire agency may have detected it.”
But improving integration among the different agencies involved in firefighting is even more vital to address, says Graham Kent, a seismologist at the University of Nevada, who was also not part of the study. “The whole way that you respond to a fire until it’s put out is like a ballet,” he says. “You’d have to choreograph (编舞) it just so,” with resources distributed at precisely the right time and place from detection to confirmation to dispatch (派遣) to extinguishing. “Fire detection is just step one; if you blow steps two through 98, all that technology... just doesn’t matter.”
Wang says his team’s next steps are to extend the device’s signal range beyond the current 100 meters, which can limit practical use, and to develop a protective wall for it. The device’s effectiveness, McCarty notes, will also need to be tested in the field.
