Cells in our brain usually send a “stop eating” signal when we've eaten enough. But in a study, researchers found that after mice ate fatty food for just two weeks, their brains brake on overeating failed.
Researchers at the University of Washington in Seattle conducted the study.They shared their findings in Science.Garret Stuber is a professor at the University of Washington.He and his team mainly focused on one brain area known-to be connected with eating behavior.This brain area contains many different kinds of cells.Researchers noticed big differences between the glutamatergic nerve cells(谷氨酸神经细胞)of the fat mice and those of the thin mice.And the earlier work by Stuber's group had suggested that these cells act like a brake on overeating.When the researchers stopped these cells from working,mice suddenly overate.They also fattened up. But it wasn't clear how these cells' activity changed as the mice changed from being slim to being fat.
“Being fat doesn't just happen overnight,”notes Stuber.To study that gradual fattening up,his group did a new study.They fed mice with high-fat food.Now and again,they used a microscope to look at how well the animals 'glutamatergic nerve cells could send out signals.During the process,they found the activity of these glutamatergic nerve cells slowed,even before the mice became fat.That cell sluggishness(怠惰)continued as the mice grew larger over a 12-week period.
The results suggest that the high-fat diet is removing the brake on overeating and becoming fat,”says Stephanie Borgland,a professor at the University of Calgary in Canada. Stuber's group doesn't know whether these brain cells will go back to normal if the mice stop eating the fatty food and slim down.It would be hard to keep monitoring the same cells over the months it would likely take for the mice to return to a healthy body weight,”explains Stuber.And it's hard to say whether similar cells control the same thing in humans.
“Having high-fat diets probably affects a much wider family of cells than those studied here,” Stuber notes. “Changes,” he says, “are probably happening across the brain.” Understanding those things might help us find better ways of limiting overeating.
1.What did researchers find in the study?
A.Mice tended to become sluggish if they often overate.
B.Having high-fat diets affected many kinds of brain cells.
C.Mice began to overeat after eating fatty food for a period.
D.The number of brain cells would drop when mice overate.
2.Why was a new study conducted?
A.To prove that fatty food was bad for health.
B.To know more about that gradual weight-gain.
C.To collect more information about the mice 's cells.
D.To observe how long it would take for the mice to grow fat.
3.What does the last but one paragraph mainly show?
A.It's still difficult to answer some questions.
B.It's hard to find the similar brain area in humans.
C.It's wrong to apply what suits animals to humans.
D.It's necessary to keep monitoring the mice for long.
4.Where is this text most likely from?
A.A personal diary.
B.A useful guidebook.
C.A science magazine.
D.An adventure novel

Air pollution may be causing baldness, scientists have shown for the first time. A new study found that fine particulate matter emitted by cars would damage the skin that holds hair follicles (毛囊) in place. A series of laboratory tests on human cells showed that levels of the crucial proteins needed for hair to grow and be retained decreased when they were exposed to pollution particles. While there is a growing body of evidence showing how these tiny particles can damage internal health, including by entering the bloodstream through the lungs, this is the first to demonstrate such a risk to the surface of the body.
The study was conducted by exposing cells from the human follicle dermal papilla cells(HFDPCs), to various concentrations of PM10-like dust and diesel particles (柴油颗粒). After 24 hours the researchers performed a process, known as western blotting, to detect the levels of specific proteins in the cells.
The results showed that the presence of PM10 and diesel particles decreased levels of B-catenin, the protein responsible for hair growth. The study also revealed that the levels of three other proteins — cyclin D1, cyclin E and CDK2, which are responsible for hair growth and hair retention, were decreased by PM10-like dust and diesel particles in a “dose-dependent” manner.
Dr Hyuk Chul Kwon, who led the study at the Future Science Research Centre, said, “While the link between air pollution and serious diseases such as cancer and lung diseases is well established, there is little-to-no research on the effect of particulate matter exposure on the human skin and hair in particular. Our research explains the mode of action of air pollutants on HFDPCs, showing how the most common air pollutants lead to hair loss.”
Sources of PM include the burning of fossil fuels — petrol and diesel, as well as other solid fuels,and other industrial activities such as building, mining and the manufacturing of building materials like bricks.
“While it is difficult to escape from the surrounding pollution, limiting the time for walking in busy streets, especially during rush hour, should help reduce exposure,” said Dr Kwon. “If you are exercising outdoors, try to do so in areas that are less polluted and do not spend too much time waiting at traffic hot spots such as traffic lights.”
1.What did the new study find?
A.Air pollution can do great harm to our lungs.
B.The color of our skin can be influenced by air pollution.
C.Serious air pollution can probably prevent hair from growing.
D.Air pollution can affect hair growth by entering the bloodstream.
2.What is western blotting used to do?
A.To discover the protein helpful for hair growth.
B.To show the protein contents in the cells.
C.To compare different proteins in the cells.
D.To analyze the composition of hair cells.
3.What can we learn from Dr Hyuk Chul Kwon’s words?
A.His new research is superior to previous research.
B.The research he conducted is really of great importance.
C.The results of his new research need to be further improved.
D.A link between air pollution and diseases needs to be established.
4.What does Dr Kwon advise us to do?
A.To do as much exercise as possible.
B.To take action to reduce air pollution.
C.To avoid being exposed to air pollution.
D.To take public transport to avoid traffic jams.

Haw wondered why he had always thought that a change would lead to something worse.Now he realized that change could lead to something better.
“Why didn't I see this before?”he asked himself.
Then he raced through the Maze with greater strength and agility.Before long,he found a Cheese Station and became excited as he noticed little pieces of New Cheese near the entrance.
They were types of Cheeses he had never seen before,but they looked great.He tried them and found that they were delicious.He ate most of the New Cheese bits that were available and put a few in his pocket to have later and perhaps share with Hem.He began to regain his strength.
He entered the Cheese Station with great excitement.But,to his disappointment,he found it was empty.Someone had already been there and had left only the few bits of New Cheese.
He realized that if he had moved sooner,he would very likely have found a good deal of New Cheese here.
Haw decided to go back and see if Hem was ready to join him.
As he retraced his steps,he stopped and wrote on the wall:
The quicker you let go of old cheese,the sooner you find new cheese.
After a while,Haw made his way back to Cheese Station C and found Hem.He offered Hem bits of New Cheese,but was turned down.
Hem appreciated his friend's gesture but said,”I don't think I would like New Cheese.It's not what I'm used to.I want my own Cheese back and I'm not going to change until I get what I want.”
Haw just shook his head in disappointment and reluctantly went back out on his own.As he returned to the farthest point he had reached in the Maze,he missed his friend,but realized he liked what he was discovering.Even before he found what he hoped would be a great supply of New Cheese,if ever,he knew that what made him happy wasn't just having Cheese.
He was happy when he wasn't being run by his fear.He liked what he was doing now.
Knowing this,Haw didn't feel as weak as he did when he stayed in Cheese Station C with no Cheese.Just realizing he was not letting his fear stop him,and knowing that he had taken a new direction,nourished him and gave him strength.
Now he felt that it was just a question of time before he found what he needed.In fact,he sensed he had already found what he was looking for.
He smiled as he realized:
It Is Safer To Search In The Maze Than Remain In A Cheseless Station
Haw realized again,as he had once before,that what you are afraid of is never as bad as what you imagine.The fear you let build up in your mind is worse than the situation that actually exists.
He'd been so afraid of never finding New Cheese that he hadn't even wanted to start looking. But since starting his journey,he had found enough Cheese in the corridors to keep him going. Now he looked forward to finding more.Just looking ahead was becoming exciting
His old thinking had been clouded by his worries and fears.
But that had changed in the days since he had left Cheese Station C.
Now he realized it was natural for change to continually occur,whether you expect it or not change could surprise you only if you didn't expect it and weren't looking for it.
When he realized he had changed his beliefs,he paused to write on the wall:
Old Beliefs Do Not Lead You To The New Cheese
Haw hadn't found any Cheese yet,but,as he ran through the Maze,he thought about what he had already learned.
Haw now realized that his new beliefs were encouraging him to behave in a new way.He was behaving differently from the way he had when he had kept returning to the same cheeseless station.
He now knew that when you change what you believe,you change what you do.
You can believe that a change will harm you and resist it.Or you can believe that finding New Cheese will help you,and embrace the change.
It all depends on what you choose to believe.
He wrote on the wall:
When You See That You Can Find New Cheese,You Change Course
1.From the first eight paragraphs,it can be concluded that
A.Haw was eager to eat up all Cheese bits.
B.Haw cared much more about himself than Hem.
C.Haw had been reluctant to change himself before.
D.Haw has been dreaming of himself enjoying Cheese.
2.The sentences Haw wrote on the wall are intended to show
A.Haw would inspire others to make changes with him.
B.Haw had a strong desire to find New Cheese to share with Hem.
C.Haw wanted Hem to find him by following the tracks on the wall.
D.Haw has been changing his mind and action to reach his goal gradually.
3.Which of the following can express the main idea of the passage?
A.Old habits die hard.
B.A diversity leads to prosperity.
C.Action speaks louder than words.
D.Someone barks up the wrong the tree.
4.From the passage, which words can be used to describe Haw?

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
About ten years ago, my wife and I took a trip to the Grand Canyon in Arizona. I didn't like to carry all my keys in my pocket during a hike, so I took away the key to the car and left the rest in the car. When we came back, I put the key somewhere in the car without reattaching it to the key ring. Then we made a fire, cooked some food, and went to sleep in the back of the SUV.
The next morning, we were cleaning up our campsite when I saw a bird inside my car. I walked over, and it flew away. When we got in the car to go home, I couldn't find the key. We searched and searched even emptying out the car completely, but it was gone.
Then it hit me that the bird must have taken it. After all, those birds are known for stealing shiny things and decorating their nests with them. Keys are shiny. The bird was the thief! It made perfect sense to me. So I decided to find its nest.
But there is a problem: As everyone knows, the Grand Canyon is a little large in area, so I didn't like my chances of actually finding a certain nest belonging to a certain bird in a certain tree in all that space. But what other choice did I have?
My wife was not encouraging me. She said, “Are you crazy? You'll never find it! The Grand Canyon is the biggest hole on Earth!” I didn't answer and walked steadily forward until her laughter died away.
I struggled to keep hope as I searched dozens of trees and tracked every singing bird. It was like searching a needle in the sea. But, oh, how great my victory would be when I held the missing key from the bird's nest.
