Camping is a great way to enjoy nature. You can breathe fresh air, cook over a campfire and sleep under the stars. However, camping also means various troubles, including dealing with bugs, bad weather and few, if any, toilets. 1.But there is a way to enjoy the natural world without giving up the comforts at home. It’s called glamping, and interest in it has been growing since 2007!
Glamping, made up by joining the words glamorous(有魅力的) and camping, is a new word. 2.Since around 600 B.C. Nomadic Mongolians have enjoyed the benefits of glamping. Their tents were so comfortable that they inspired the design of modern glamping tents!
There are many reasons why you should consider glamping for your next vacation. One of them is that glamping gives you access to some beautiful places. 3.Nowadays, glamping can be less expensive than staying in a hotel, but you can still enjoy the modern comforts of a hotel!
4.Glampsites often use eco-friendly materials and avoid using much plastic. So, there is less waste, and the area stays beautiful.
No matter what kind of experience you’re looking for, a glampsite exists for you. From Three Camel Lodge in Mongolia to Clayoquot Wilderness Resort in Canada, adventure is waiting for you. Sites can include a spa, a swimming pool and dinner under the stars. Activities can include exploring on horseback or camel and sightings of elephants, mountain sheep or tigers. 5.
A.Every year a large number of people go camping.
B.You don’t have to give up beauty for comfort!
C.A wide variety of glamping experiences are available all over the world.
D.These troubles can discourage people from ever trying camping.
E.But it describes an activity that people have been doing for ages.
F.You can also help other campers.
G.Another reason to go glamping is that it’s good for the environment.
In recent years, experiments examining exercise and weight loss have found that people lose far much less weight than expected, considering how many additional calories(卡路里) they are burning with their workouts.
Scientists have guessed that exercisers are likely to become hungrier and eat more after working out. They also may sit longer when not doing exercise. Together or separately, these changes could make up for the extra energy used during exercise.
To prove that possibility, scientists came up with the idea of using infrared light(红外线) to track mice’s movements in their cages. Then software can use that information to analyse their daily physical activity.
So the researchers prepared special cages, putting inside some locked running wheels, and let mice roam(闲逛) and explore for four days in the cages. This provided the researchers with information about how many calories each mouse burned every day.
Then the wheels were unlocked and for nine days, the mice could run at will, and they could decide how much to eat and when to get off the wheels, walking around. The mice,which enjoyed running, jumped readily on the wheels and started to run. On and off the wheels, they could run for hours. They showed a following height in their daily energy expenditure(支出) since they had added exercise to their lives.
But they did not change their eating habits. Although they were burning more calories, they did not eat more. They did, however, change how they moved. They now usually jogged on their wheels for a few minutes, jumped off, rested or roamed in a while, and then climbed back on the wheels, ran, rested, briefly roamed, and it repeated. These changes in how they spent their time almost counteracted(抵消) the extra calorie costs from running, says Daniel Lark, who led the new study.
What caused the running mice to run less is still uncertain. ''But it does not seem to have been tiredness or lack of time; wheel running is not arduous for mice, and does not fill their waking hours.'' Dr. Lark says.
Instead, he says, it is likely that the animals’ bodies and brains sensed the increasing energy expenditure when the mice began to run and sent out biological signals that somehow advised the animals to slow down, save energy and lose weight.
Mice will never be people, of course, so we cannot say whether the results of this would directly apply to us, Dr. Lark says. But the results do indicate that if we hope to lose more weight through, we should watch what we eat and try not to move less while we work out more.

C.They spent less time roaming in the cage. D.They didn't need rest after running the wheels.
3.The underlined word ''arduous'' in paragraph 7 is closest in meaning to _______.
A.tiring B.energetic C.difficult D.different
4.Which of the following statements may Dr. Lark agree with?
A.Wheel running costs the same amount of energy as roaming does.
B.The mice ran more because they really wanted to lose weight.
C.The experiment is a failure because the results don't apply to humans.
D.It might not be tiredness that caused the mice to run less.
5.The purpose of writing this passage is _______.
A.to prove that scientists' guess about exercising is wrong
B.to introduce a recent research on exercise and weight loss
C.to analyze how wheel running changes mice's movements
D.to explain why eating and running are bad for exercisers
