Experts say the temperature in Eyjafjallajokull's hole appears to have fallen to 100C, meaning it is now producing steam, not magma（岩浆）.
But officials warned that it was too early to say whether the eruption was over completely.
Ash clouds from the volcano grounded thousands of flights last month.
Steinunn Jakobsdottir, a geophysicist from the Icelandic Meteorological Office, told the BBC that the volcano was "kind of not active for the moment".
"The history of the volcano is such that it calms down and then it gets energy again," she said.
"There are still earthquakes under the volcano, and the small earthquake is still not quite down to what it was before the eruption."
'Difficult to say'
Magnus Gudmundsson, of Iceland University, flew over the volcano on Sunday and said information from heat cameras showed the temperatures at the crater had fallen below 100C.
But he told the AFP news agency that nothing was promised and that the previous eruption at the volcano had lasted 13 months, from 1821-23.
"It stopped and started again several times with different intervals（间隔）, so it's difficult to say, difficult to give a timeline," he said.
He also said it was impossible to say whether the neighbouring Katla volcano - a much larger mountain - might also erupt.
At the height of its activity, the volcano sent out huge clouds of ash, which led to airlines grounding their planes for fear it could interfere with plane engines.
It was the biggest action of closing airspace in Europe since World War II, and affected at least 10 million passengers worldwide.What do expert think Eyjafjallajokull is like now?

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate, you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo(竹子) . Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶) will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied(多样化) diet . The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.We can infer from the text that humans and animals _________.
| A．depend on one sense in choosing food |
| B．are not satisfied with their food |
| C．choose food in similar ways |
| D．eat entirely different food |
Which of the following eats only one type of food?
| A．The white butterfly. | B．The small bird. |
| C．The bear. | D．The fox. |
Certain animals change their choice of food when ___________.
| A．the season changes |
| B．the food color changes |
| C．they move to different places |
| D．they are attracted by different smells |
Happy April Fool’s Day! In celebration of the day, we have put together a list of some of the greatest hoaxes (恶作剧) in history. They are the lies that have been designed for innocent people who are ready to believe them.
INSTANT COLOR TV
In 1962 there was only one TV channel in Sweden, and it broadcast in black and white. The station’s Kjell Stepson, appearing on the news to announce that thanks to a newly developed technology, all viewers could now quickly and easily transform their existing sets to display color reception. All they had to do was pull a nylon (尼龙) stocking over their TV screen, and they would begin to see their favorite shows in color. Reportedly, hundreds of thousands of people, were taken in. Actual color TV transmission only started to appear in Sweden on April 1, 1970.
SAN SERRIFFE
In 1977 the British newspaper The Guardian published a special seven–page supplement(增刊) in honor of the tenth anniversary of San Serriffe, a small republic located in the Indian Ocean. A series of articles affectionately asked for more information about the beautiful holiday spot. Few noticed that every thing about the island was made up.
NIXON FOR PRESIDENT
In 1992 American National Public Radio’s Talk of the Nation program announced that, Richard Nixon, in a surprise move, was running for President again. His new campaign slogan was, “ I didn’t do anything wrong, and I won’t do it again.” Accompanying this announcement were audio clips(片断) of Nixon delivering his election speech. Listeners responded immediately to the announcement, flooding the show with calls expressing shock and anger. Only during the second half of the show did the host John Huckleberry reveal that the announcement was a practical joke. Nixon’s voice was copied by comedian Rich Little.Which of the following countries is NOT mentioned in the text?

The smell of fresh air is becoming something of a distant memory, thanks to our increasing use of fragrance (香气). From air fresheners to scented (有香味的) candles, we live in a world of scent.
Recent figures show seven in ten people use air fresheners or scented candles to keep our homes smelling sweet. Yet recent records suggest that perfumed products could affect our health, causing problems including allergies (过敏), headaches and asthma (哮喘) .
One leading expert believes nearly a third of people suffer health effects from being exposed to scents. A major problem is so-called “contact” allergy—where perfumes and scented products cause eczema (湿疹) when they come into contact with the skin. About one in 20 is thought to be affected by fragrance allergy.
“Often it may not be immediately obvious that you have developed a fragrance allergy,” says Dr. Baron. “You don’t react immediately. Gradually, as you are exposed more and more, the body increases its reaction, until it becomes noticeable to you.”
People with pre-existing eczema are particularly vulnerable (易受影响). “The eczema worsens in areas in contact with perfumes,” says Dr. Baron. “But even those without allergies can be at risk of fragrance allergy.” You can become suddenly allergic to perfumes and personal care products that you have been using for years. “Even if you know which fragrance causes a problem, it can be difficult to avoid, as most personal care products –soap, shampoo, sun cream and washing powder—contain fragrances,” says Dr. Baron.
And strong scents can also cause headaches. Fragrances activate the nose’s nerve cells, stimulating the nerve system associated with head pain. To minimize risk, sufferers are advised to minimize the contact.
“Fragrance suggest cleanliness – yet people are smelling a potentially dangerous chemical mixture,” says Anne Steinemann, professor of the University of Washington. “We often use them to mask one problem – as with air fresheners – but create a greater one – adding poisonous chemicals to the air.”What is the text mainly about?
| A．The world trend of using fragrance. |
| B．The benefits of using non-fragranced products. |
| C．The health problems caused by fragrance |
| D．The ways of removing allergy. |
According to Dr. Baron, .
| A．our bodies have an immediate reaction to fragrance. |
| B．seven in ten have suffered fragrance allergy. |
| C．fragrance can affect people who don’t have allergy |
| D．people can avoid contacting with fragrance easily |
Which of the following questions does the text NOT answer?
| A．Which products contain fragrance? |
| B．What’s the influence of fragrance in the air? |
| C．What are the air fresheners made up of? |

The following paragraph might discuss .
| A．the asthma caused by strong scents. |
| B．people’s efforts to protect fresh air. |
| C．the methods of curing eczema |

Barcodes (条形码) aren’t given much thought by the majority of consumers, but these codes were fairly recently applied in a working fashion in 1970.
A small food store owner decided one day that keeping records of the inventory (存货) of his stock and the associated prices were an extremely laborious process, and so, in 1948, he contacted the The Drexel Institute of Technology in a bid to work towards a solution. Bernard Sliver rose to the challenge and set out to study the problem, and began working on a solution involving an automatic way of keeping track of items that had been sold. Silver and a group of students from the institute realized their answer in the form of ultraviolet light (紫外线), ink and a scanner.
The system worked initially, but possessed some negatives. It was incredibly costly to carry out on a large scale and the system was also unstable. If the invention was to become commonplace (寻常的事) in grocery stores, these two problems had to be solved.
The patent (专利)for the bar code system was filed by Sliver and one of his students, Woodland. The patent was not granted immediately; in fact it took three years for the patent agency to grand their invention patent for the barcode, occurring on 7th October, 1952.
Despite the patent being issued, the system was still not welcomed by the majority of store owners. It was not until 1966 that the system began moving its way into more and more grocery stores. This system was soon criticised, as there was no central mechanism for controlling uniformly coded items. In 1970, Logicorn developed the Universal Grocery Products Identification code (UGOIC), soon shortened to Universal Identification Number (UPC). It was Marsh’s superstore, in Troy, which was the very first store to install this complex barcode reading system, and its popularity has soared (升温) ever since, and is obviously now commonplace in all types of stores worldwide.What is stressed in the second paragraph?

At Blossom End Railroad Station, 22-year-old Stanley Vine sat, waiting for his new employer. The surrounding green fields were so unlike the muddy landscape of war-torn France. After four horrible years as an army private fighting in Europe, Stanley had returned to England in February 1946. Armed now with some savings and with no prospects for a job in England, he answered a newspaper ad for farm help in Canada. Two months later he was on his way.
When the old car rumbled (发着辘辘声) toward the tiny station, Stanley rose to his feet, trying to make the most of his five foot and four inches frame. The farmer, Alphonse Lapine, shook his head and complained, “You’re a skinny thing.” On the way to his dairy farm, Alphonse explained that he had a wife and seven kids. “Money is tight. You’ll get room and board. You’ll get up at dawn for milking, and then help me around the farm until evening milking time again. Ten dollars a week. Sundays off.” Stanley nodded. He had never been on a farm before, but he took the job.
From the beginning Stanley was treated horribly by the whole family. They made fun of the way he dressed and talked. He could do nothing right. The humourless farmer frequently lost his temper, criticizing Stanley for the slightest mistake. The oldest son, 13-year-old Armand, constantly played tricks on him. But the kind-hearted Stanley never responded.
Stanley never became part of the Lapine family. After work, they ignored him. He spend his nights alone in a tiny bedroom. However, each evening before retiring, he lovingly cared for the farmer’s horses, eagerly awaiting him at the field gate. He called them his gentle giants. On Saturday nights he hitch-hiked into the nearest town and wandered the streets or enjoyed a restaurant meal before returning to the farm.
Early one November morning Alphonse Lapine discovered that Stanley had disappeared, after only six months as his farmhand. The railway station master, when questioned later that week, said he had not seen him. In fact no one in the community ever heard of him again. That is, until one evening, almost 20 years later, when Armand, opened an American sports magazine and came across a shocking headline, “Millionaire jockey (赛马骑师), Stanley Vine, ex-British soldier and 5-time horse riding champion, began life in North America as a farmhand in Canada.”Stanley Vine decided to go to Canada because ___________.
| A．he wanted to escape from war-torn France |
| B．he wanted to serve in the Canadian army |
| C．he couldn’t find a job in England |
| D．he loved working as a farmhand |
Which of the following is TRUE according to the passage?
| A．Stanley joined the French army when he was 18 years old. |
| B．On the farm Stanley had to milk the cows 14 times a week. |
| C．The Lapine family were very rich but cruel to Stanley. |
| D．Stanely read about the job offer in a newspaper. |
What did Stanley like doing after work each day?
| A．Hitch-hiking to different towns. |
| B．Caring for the farmer’s horses. |
| C．Wandering around the farm alone. |
| D．Preparing meals on the farm. |
Why was Armand so astonished when he read about Stanley in the magazine?
| A．He didn’t know Stanley had been a British soldier. |
| B．He had no idea Stanley had always been a wealthy man. |
| C．He didn’t know his father paid Stanley so little money. |
| D．He didn’t expect Stanley to become such a success. |
