Ants know when an earthquake is about to strike, researchers have discovered. Their behavior changes significantly prior to the quake and they resume normal functioning only a day after it. Gabriele Berberich of the University Duisburg-Essen in Germany presented these findings on Thursday at the European Geosciences Union annual meeting in Vienna according to LiveScience.
Berberich and her colleagues discovered that red wood ants preferred to build their colonies right along active faults in Germany. They counted 15,000 mounds （土堆)）lining the faults. These faults are the places where the earth violently bursts in earthquakes.
Using a special camera that tracked changes in activity. Berberich and her colleagues tracked the ants round the clock for three years, 2016 to 2019. They found that the ants' behavior changed only when the quake was over magnitude （级数）2. There were 10 earthquakes between magnitude 2.0 and 3.2 during this period, and many smaller ones. Humans can also sense quakes of over magnitude 2 only.
According to Berberich, normal ant activity consists of going about collecting food etc,during the day and resting in the night But before an earthquake, the ants didn't go back to their mound in the night and moved around outside it. This strange and abnormal behavior continued till a day after the earthquake, Berberich told a news conference, according to Livescience.
How do ants know an earthquake is coming? Berberich suggested that they could either be picking up changing gas emissions or noting tiny changes in the Earth's magnetic fields （磁场）. "Red wood ants have special cells which can detect changes in carbon dioxide levels. They also have special cells for detecting electromagnetic fields." she said. Berberich and her colleagues are planning to continue the research in areas where there are more and bigger earthquakes

According to the US Geological Survey, about seven million earthquakes strike worldwide every year—but fortunately, only about 1500 of these are of a magnitude(震级) of 5 or greater on the Richter scale. Certain areas, such as California and Japan, are more prone to earthquakes than others. Although the chance of being caught in “The Big one” is remote, it’s wise to be prepared if you live in a region where earthquakes are common.
Educate your family about earthquakes before a big one strikes. For example, they need to know to take shelter in a doorway or under a strong object if indoors, and never to run outdoors if they are inside. If outside, they need to know to stay away from power lines and buildings where objects could fall.
Teach family members how to turn off gas or water lines or electrical power that may need to be shut off after a quake if severe damage occurs.
Develop a plan. Where will your family meet in the event of a disaster? What if some people are at work or school? How will you know if they are safe? Where will you all meet up?
Pack a preparedness kit(衣物装备) and keep it in a safe location. In a major earthquake, it’s possible that you won’t be able to get into your house. Keep supplies in your car trunk or an outside storage shed if possible. Pack whatever your family is likely to need, enough for three days to a week, including food, water, medication, first aid and personal hygiene supplies, flashlights, a portable radio, blankets, clothes and shoes, cash, or camp stove, candles, matches or lighters, and a whistle.
Consider earthquake insurance for your home if you live in an earthquake-prone area. Regular homeowner’s insurance doesn’t cover earthquake damage.
1.The underlined words “prone to ” in paragraph 1 can be replaced by___________.
A. likely to suffer B. frequent to explore

A. about 1,500 earthquakes happen every year
B. people should store some clothes in their houses in advance
C. family members should meet in their home after an earthquake
D. people suffering earthquakes often should buy earthquake insurance
4.What would be the best title for the passage?

Hollywood is on the edge of a nervous breakdown. Worried about an industry wide writers’ strike, struck by a series of theater-chain bankruptcies(破产), burdened with unreasonable corporate profit, requirements and seemingly incapable of producing consistently creative movies, the American film industry is in a period of soul-searching. There’s little doubt it will survive this crisis. But most insiders agree there is disease at both ends of the business—where film are produced, and where they’re shown---that may take years to overcome.
While annual box-office income increases for nine straight years, largely due to increased ticket prices, the number of actual tickets sold declined for the second year in a row. The construction boom has added nearly 10,000 theaters(more than 200,000 more seats) in the last five years. But due to a static(静止的)audience base, eight major chains have gone into bankruptcy and several others are in terrible financial situations.
In fact, insiders say, Hollywood is now in a business it does not want to be in. “There’s a general problem in that the companies that have the most consistent output of material are least interested in what they’re making,” says former 20th Century Fox CEO, Bill. And, Bill adds, “We’re in a period where movies are getting bigger and more costly and less interesting and fulfilling to an audience.”
Today the studios are under the stress to increase profit margins(营业利润) for their corporate parents, and profit margins are hard to control in a business whose products are seen as impulse buys(即兴购买). Other business can increase profits by cutting costs—buying cheaper material, or making the candy bar smaller. Not Hollywood.
“What we’re cutting is risk,” says the head of one major studio, who asked not to be named, “And risk is what great film has always demanded.” While the studios are avoiding risky concepts, their competitors in the home entertainment business have been expanding the boundaries of the imagination. It was this pressure---in electronic games, the Internet, EVDs----that forced the movie theater chains into a self-destructive craze of expansion.
1.Which of NOT the worry of the American film industry according to the passage?
A. Theater-chain bankruptcy
B. Lack of the advertisement funds
C. The stress to increase corporate profit
D. Being unable to produce creative movies
2.What has directly caused major theater-chains in terrible financial situations?
A. Bigger movies
B. More costly movies
C. Increased ticket prices
D. More theaters but an unchangeable audience base
3.What do we know about the profit of the film industry?
A. It’s not easy to control the profit
B. The studios can shorten the material
C. Cutting the cost can increase the profit
D. The studios can buy cheap material to increase profits
4.What’s the main idea of the passage?
A. Hollywood will survive financial crisis
B. Hollywood is on the edge of destruction
C. It’s hard to increase the profits of the studios
D. The construction boom leads to theater-chain bankruptcies

There is nothing better than having a good scratch when an itch (痒) strikes. But how does scratching stop an itch?
According to a study published in the journal Nature by the scientists from the University of Minnesota, US, the relief you feel does not come from your skin, but from inside our spinal cord (脊柱).
The scientists injected a kind of chemical called histamine(组胺)into a monkey’s legs to produce an itch. The activity in part of the monkey’s spinal cord started to become very strong in response. The scientists then scratched the itchy legs and found that the activity in the spinal cord quickly weakened.
The sudden change in the activity happened because scratching blocked that part of the monkey’s spinal cord. As a result, it could no longer send signals to the brain telling it about the itchy feeling. This is why scratching makes mosquito bites feel better at least temporarily.
“It’s a very important study for itching is a major problem for millions of patients,” said Gil Yosipovitch, PhD, founder of the International Forum for the Study of Itch.
Around 50 different diseases can cause serious itching, including AIDS and kidney diseases.
Scratching might make things more comfortable for small, ordinary itches, but for people with more serious diseases, it can make matters worse. Sometimes an itch can be s0 strong that it keeps the sufferers awake at night, throwing them into a terrible emotional disturbance. Scratching hard can lead to serious skin damage or infection.
The next step for scientists is to discover exactly how itches are reduced when spinal cord signals are stopped. This could help them develop medicines that act in the same way to reduce itching. Patients suffering from serious itching will finally be freed from their misery without tearing up their skin, according to Glenn Giesler, leader of the research.
1.What is the key to determining the feeling of an itch?
A. The skin.
B. The brain.
C. The spinal cord.
D. The bitten tissue.
2.Which is the correct order to show how the experiment was done?
a. The monkey began to have a feeling of itches.
b. The monkey became sensitive to the chemicals.
c. The scientists scratched the itchy legs of the monkey.
d. Scratching made the brain unable to get signals from the spinal cord.
e. To make itches, an injection of histamine was given to the monkey’s legs.
A. e-c-b-d-a
B. e-b-a-c-d
C. d-c-b-e-a
D. b-a-e-d-c
3.What can be inferred from the passage?
A. The cause of itches has not been found yet.
B. All the itches can be got rid of by scratching.
C. Some patients stay awake because of severe itches.
D. Serious itching and scratching can affect people physically and mentally.
4.What may scientists do next according to the passage?
A. They will wipe out itches forever
B. They will announce the findings to the world.
C. They will treat the itch sufferers in a traditional way.
D. They will develop a kind of medicine to relieve itches.
