Eating at a slow speed may help reduce hunger, the U.S. researchers said on Monday. Previous research suggests that the ability to control energy intake may be affected by the speed at which we eat, and a high eating rate may damage the relationship between the sensory signals and processes that control how much we eat.
In order to learn more about the link between eating speed and energy intake, researchers examined how eating speed affects calories consumed during a meal in both normal-weight subjects as well as overweight or obese subjects.
In the new study, a group of normal-weight subjects and a group of overweight or obese subjects were asked to consume two meals in a controlled environment. All subjects ate one meal slowly, took small bites, chewed thoroughly, and paused and put the spoon down between bites, and ate a second meal quickly, took large bites, chewed quickly, and did not pause and put the spoon down.
At the conclusion of the study, the researchers found only normal-weight subjects had a statistically significant reduction in caloric consumption by eating slowly. “A lack of statistical significance in the overweight and obese group may be partly due to the fact that they consumed less food during both eating conditions compared to the normal-weight subjects,” Professor Meena Shah said, “it is possible that the overweight and obese subjects felt more self-conscious, and thus ate less during the study.”
Despite the differences in caloric consumption between the normal-weight and overweight and obese subjects, the study found some similarities. Both groups felt less hungry later on after the slow meal than after the fast meal, which indicates that greater hunger suppression(抑制)among both groups could be expected from a meal consumed more slowly. Also, both the normal-weight and overweight or obese groups consumed more water during the slow meal. “The higher water intake during the slow eating condition may have affected food consumption,” said Shah. According to Shah, slowing the speed of eating may help suppress hunger levels and “may even improve the enjoyment of a meal”.
The findings were published in the Journal of the Academy of Nutrition and Dietetics.

Turtles may be cute, but they are also slow and clumsy, which doesn’t really help them when they are trying to cross train tracks. Luckily, for the turtles in Japan’s Hyōgo Prefecture, railway operators and a local aquarium teamed up to find a solution.
Between 2002 and 2014, disruptions (中断) of train operation caused by turtles were reported 13 times, with many more probably going unreported. That is why, in 2015, West Japan Railway Co. and Suma Aqualife Park in Kobe joint forces to prevent tragic turtle deaths on the tracks and unnecessary train delay. After running a series of tests and experiments, they came up with a U-shaped ditch (沟渠 ) that collects the turtles, preventing them from getting stuck between the metal tracks and getting crushed to death.
Tests showed that turtles trying to cross the train tracks often fall into the space between them, which leaves them with no other option than to walk between them. Sadly, this causes some of them to get stuck between the metal tracks at junctions(交叉口), and they unavoidably get crushed to death when the points blades(叶片)move.
“The turtles are basically just going about their daily business and have to cross the lines to get to a pond,” a railway spokesperson said. “When the points blades move, unfortunately they get squashed between them and die. They can cause long delays to operations so we consulted with a turtle specialist to find the best way to help them.”
The U -shaped concrete ditches installed at several critical points along the train lines near the city of Kobe catch the turtles at danger of getting stuck between the tracks. They allow the turtles to get past the junctions safely. 10 turtles were reportedly saved in the first month since the U-shaped ditch was put to use in November 2015.
1.What’s the best title of the text?
A.An Important Invention in Japan
B.The U-shaped Concrete Ditches
C.Turtles Crossing Train Tracks in Danger
D.Japan’s Clever Solution to Help Turtles Cross Train Tracks
2.What does Paragraph 2 mainly talk about?
A.Why the U-shaped ditch is invented.
B.The turtles’ terrible conditions.
C.The train delay caused by turtles.
D.How the turtles go through the tracks.
3.What does the underlined word “them” in Paragraph 3 refer to?
A.The turtles. B.The trains.
C.The train tracks. D.The points blades.
4.What can we infer about the ditches?
A.They are installed on the railway tracks.
B.They can prevent turtles from escaping.
C.They are easy to trap the turtles.
D.They are helpful for turtles to cross train tracks.

Researchers in the United States say eating less can slow the aging process of cells in the body. The researchers studied mice, not people.
1. One group was able to eat as much as it wanted. The other animals in the other group were limited to eat. Their diet had 35 percent fewer calories than the first group of mice.
The mice with the diet restrictions (限制) were more energetic and suffered fewer diseases. They were not just living longer, they seemed to stay younger for a longer period of time. When you restrict calories (in mice), there is a direct increase in lifespan—the average age of the animal.2.
But how? The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes (核糖体). Ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down.3. This, in turn, keeps cells and the entire body functioning well.
Earlier studies have suggested a link between calorie restrictions and slowed aging.4.
Calorie restriction as a way to slow aging has not been tested in humans. But the main finding for people is the importance of taking care of our bodies.5. And this may help us make better decisions about what we eat.
A. The less we eat, the healthier we are.
B. Researchers studied two groups of mice.C. This finding is good news if you are a mouse.
D. This gives the cells more time to repair themselves.
E. The findings help to explain how exactly our bodies age.
F. However, this is first to show how the ribosomes can influence aging.
G. Calorie restriction caused real biochemical changes that slowed down the rate of aging.

New Holland honeyeaters are experts at sounding the alarm when there's danger, according to new research from biologists at the Australian National University(ANU)and the University of Cambridge.
Study authors, Dr. Jessica McLachlan and Professor Rob Magrath, found honeyeaters can spread the word in the blink of an eye, using a two-stage alarm.
It's particularly effective when they are threatened by fast-moving birds of prey.
"When a hawk is swooping down, its target has only a second to flee to cover-a split second can make the difference between life and death," Dr. McLachlan said.
"But animals often signal urgent danger using repeated notes, which makes sure others hear the warning but it takes a long time to deliver."
"So there's a problem. How to send a lightning-fast message in a long call?”
New Holland honeyeaters solve this problem elegantly. They "front-load" information about urgency into the first note of their alarm call, so other honeyeaters can respond quickly.
The clever honeyeaters follow this up with more notes to reinforce the message and signal how long to remain hidden.
"They use a long call, with lots of notes, to make sure the message is heard," Professor Magrath said." And the more notes, the more urgent the danger."
"But they also modify the first note to indicate if it's necessary to take immediate cover. So it's a two-part message that is quick, reliable and informative."
The technique is so effective the authors expect to see other species adopt it.
"Many other species modify alarm calls as the threat increases, but there is surprisingly little known about how fast they convey the message," Professor Magrath said.
The researchers conducted their study in Canberra's National Botanic Gardens over a period of several years.
"These birds live in the Gardens and are used to having people around. This helped us to record natural interactions with their predators(捕猎者),such as sparrow hawks and currawongs, and to video the honeyeaters' responses to different alarm calls," Professor Magrath said.
1.According to Dr. Jessica McLachlan,______
A.speed counts when it comes to honeyeaters' life or death
B.the second-part message in a honeyeater's call is more reliable
C.the message about where to take cover is conveyed very fast
D.the urgency degree relies on the first note in a honeyeater's call
2.What does"they"in Paragraph 12 refer to?
A.alarm calls B.modified notes
C.other species D.clever honeyeaters
3.The researchers' findings are mainly based on
A.the comparison between honeyeaters and other birds
B.the analysis of length of alarm calls made by honeyeaters
C.the record of the honeyeaters' response and signal transmission
D.the observation of birds in Canberra's National Botanic Gardens
