To American visitors, Iceland is a very interesting country, partly because it is different in so many ways from he or she is used to seeing at home. There are quite a few things that are not done, or that do not exist on the island—quite a few “No's”.

    There is no pollution, for instance, no dogs are permitted in Reykjavik, the capital. There is no television on Thursdays or during the whole month of July, and only three hours of black and white TV the rest of the time. There is no hard liquor（酒） on Wednesdays and no beer at any time. There is no handguns; only one prison of thirty-five rooms in the whole land—an admirable figure, even for a small country of 313,376 people.

There is no army, air force or navy. There is no tipping（给小费） for anything. There are no large stores open on Saturdays or Sundays. Since Iceland is located just under the Arctic Circle, there is no darkness in summer and no daylight in winter. But thanks to Gulf Stream, the climate is rather mild, with temperatures between 34 degrees and 52 degrees in July.

The rules on television liquor and guns are the result of government decisions. But the absence of pollution is because of in great part the fact that Iceland gets its power from the thousands of hot springs(泉水) that come out of the ground. They provide all the energy needed by the country. In fact, Iceland uses only 3 percent of all its available power.

    Iceland has been described as a democratic（民主的） independent country where more fish are caught and more books published per person than anywhere else in the world. The Icelanders have always felt a particular love for literature. They wrote their first books in the ninth and tenth centuries AD. These works were poems and tales about the kings, heroes, and heroines of Iceland and Norway. At first, the stories were remembered and passed from generation to generation. They were finally written down between 1140 and 1220. The Icelanders have never stopped writing ever since. “Rather shoeless than bookless,” they proudly say.

    The young dolphin swam in the waters off Brisbane, Australia, and found his seafood dinner. Suddenly he realized that he was not the only hungry predator(捕食者)in the area. A ten-foot tiger shark aimed at the same fish. The dolphin refused to give up the meal and dashed to the shark. The shark attacked him, biting down hard into his back. {#blank#}1{#/blank#}

    Later, on the sandy beach nearby, staff at the Tangalooma Resort were shocked to see the severely wounded male. He was a regular visitor, a playful 12-year-old dolphin called Nari. “We've known him all his life, since he was a baby,” says resort director Trevor Hassard. {#blank#}2{#/blank#}The wound measure about a foot long and more than an inch deep. He took photos of Nari and sent them to vets at Sea World, a local marine mammal park. They agreed that Nari needed emergency care.

    The next day, Sea World staff traveled to the beach to catch Nari.{#blank#}3{#/blank#}Nor did he appear the next evening. Everyone was depressed and worried about him.

    {#blank#}4{#/blank#}“I had started thinking the worst,” Hassard says. “Words can't describe how excited we were.” Six rescuers surrounded Nari and carried him to Sea World. The vets performed an operation to remove the dead flesh from around the bite. Nari was then moved to a special pool where his wound was cleaned and treated regularly.

    {#blank#}5{#/blank#}Sea World decided to tansort Nair back to his home beach. Hassard had worried that the other dolphins might reject Nari after such a long absence. That concern disappeared when Nari's friend Echo instantly recognized him and moved close to his side.

A. But Nari didn't show up

B. Three days later, Nari finally turned up.

C. He felt quite worried when he took a close look at Nari's injury

D. After seven weeks, Nari was fully recovered but growing restless.

E. Shark researchers are trying to warn people to escape without being eaten

F. The five-meter-long dolphin simply swam away, disappearing into the water below.

G. Luckily, the wounded dolphin managed to escape from the shark's biting with violent struggle.

    We all know that the cost of heating our homes will continue to be a significant burden on the family budget. Now millions of people are saving on their heating bills with the EP portable heater. With over one million satisfied customers around the world, the new EP heats better and faster, saves more on heating bills, and runs almost silent.

    The EP has no exposed heating parts that can cause a fire. The outside of the EP only gets warm to the touch so that it will not burn children or pets.

    The EP will not reduce oxygen in the room. With other heaters, you'll notice that you get sleepy when the heat comes on because they are burning up oxygen.

    The advanced EP also heats the room evenly, wall to wall and floor to ceiling. It comfortably covers an area up to 350 square feet. Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room. And they only heat an area a few feet around the heater. With the EP, the temperature will not vary in any part of the room.

    The EP comes with a 3-year warranty (保修) and a 60-day, no questions asked, satisfaction guarantee. If you are not totally satisfied, return it at our expense and your money will be given back to you.

    Now we have a special offer for 10 days, during which you can enjoy a half price discount and a free delivery. If you order after that, we reserve the right to either accept or reject order requests at the discounted price.

Owls and Larks

    Larks are most likely to be healthy, wealthy and wise, according to the old saying.

But those who are early to bed and early to rise do not always have the upper hand, researchers say. They have found that night owls are generally brighter and wealthier than those able to get up early in the morning.

    Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late proved the kind of intelligence associated with honored jobs and higher incomes. “Larks” or “morning people”, however, often acquired better exam results, possibly because lessons are held at the wrong time of day for night owls. The researchers examined the habits and body clocks of the youngsters to determine whether they liked to stay up late and sleep later in the morning, or preferred to go to bed early and were at their peak in the morning. School performance and inductive(归纳的)intelligence, or problem solving, were measured and academic grades in the major subjects were also taken into account. The results showed that evening types scored higher than morning types on inductive reasoning, which has been shown to be a good estimate of general intelligence and a strong indicator of academic performance. They also had a greater capacity to think conceptually as well as analytically. Such abilities have been linked to innovative(创新的) thinking, more admired occupations and better incomes.

    Famous night owls include President Trump, Obama, Charles Darwin, Winston Churchill, Keith Richards and Elvis Presley. George W. Bush, who is regularly in bed by 10 p.m., Thomas Edison, Napoleon, Condoleezza Rice, who wakes at 4:30 a.m., and Ernest Hemingway are among those known as larks. Jim Horne, professor of psychophysiology at Loughborough University, said, “Evening types tend to be the more active and creative types, the poets, artists and inventors, while the morning types are the deducers(推断者), as are often seen with civil servants and accountants.” A previous study of US Air Force recruits found that evening types were much better at thinking to solve problems than larks.

    Chinese people are, quite rightly, proud of their food. However, when foreigners like Britons and Americans think of Chinese food, their impression of it is different to what you might think.

    Growing up in the UK, the Chinese food I was used to eating was food I now recognize as being from Guangdong. For example, a typical dish I would order would be pork in sweet and sour sauce, probably with some rice and spring rolls on the side. This is the type of food we generally eat because most Chinese immigrants(移民) to the UK have come from Guangdong. You can tell, because when most British people try to copy the sound of Chinese, they actually copy the sound of Guangdong people—hearing the real Putonghua is sometimes a shock to British people who have grown up thinking it sounds completely different!

    British attitudes to Chinese food may be changing, though. Chinese-American chef Ken Hom has been on British TV for 30 years, and he told BBC Food: "Chinese food at the beginning of the 80s (in the UK) was sweet and sour pork, mainly. Most Brits had the unchangeable view of Chinese food. Now you are seeing more local Chinese food from Sichuan, Hunan and other areas of China. It is no longer just Guangdong food." Similarly, to most Americans, Chinese food doesn't go too far past orange chicken and fortune cookies, but more Chinese local dishes are becoming successful, especially in big cities like New York.

    Attitudes have not quite changed completely, though. Many foreigners who live in China will be familiar with this question from a relative back at home: "Have they given you dog yet?" Yes, perhaps because people still know too little about Chinese culture, many people believe that Chinese people love to eat dog meat. And of course, some people do eat dogs, which to Americans is like "eating a member of one's family" according to Vision Times. Also, Chinese people eat many other things people in the West do not—chicken claws, duck heads and some animals' organs.

    But what do foreigners think when they come to China and taste real Chinese food? You'll be glad to know that in my experience, the impressions have been very good.

It is important for an {#blank#}1{#/blank#}(educate) to understand what makes each student tick. {#blank#}2{#/blank#}(general) speaking, I usually look {#blank#}3{#/blank#} their body language. I know when students are really interested, because they lean forward and look at me. People have a {#blank#}4{#/blank#}(tend) to lean towards whatever they are interested in. so if a student has his head lowered to look at his watch, it implies he is {#blank#}5{#/blank#}(bore) and just continuing the minutes for the class to end.
