21、Not too long ago, 41-year-old Garrett Fisher flew in a small airplane close to the surface of Europe’s largest glacier(冰川), which is in Norway. In that environment, the plane carrying a man who photographed glaciers seemed almost like a toy.
Fisher often combines two activities he loves, flying and photography, trying to photo- graph every glacier on Earth. He wants his photos to show the beauty of glaciers before some of them disappear. Scientists say many glaciers are melting or getting smaller because the Earth's average temperature is increasing. By 2100, the size of European glaciers can decrease by between 22 percent and 84 percent. Nearly all small glaciers in Norway will likely disappear. For Fisher, this means that time is running out. The melting pushes him to try to photograph them before it is too late.
As a child, Fisher lived next door to a small airport in the state of New York. His grand- father was a pilot and took Fisher on plane rides when he was a young child. His grandfather would tell him, “Whatever you set your mind to, you can do. ”
In the late 1990s, a friend told Fisher that the world’s glaciers were disappearing. This pushed him to combine his love of flying and photography to photograph the Earth's remaining glaciers. He believed he was in a race against time and that his photographs could be of great value to future generations. So, he launched Global Glacier Initiative, a non-profit group to support and show his work, and he planned to open his photos to the public for research.
Some people will ask him why he always risks flying over glaciers when satellites have already given pictures of them. Fisher says, “Satellite images can't really show the loveliness of glaciers the way my photos can. My photos show the colors and shapes as the light from the sun hits them. Science has all of the data we need. The problem is that it’s not beautiful. ”
【1】What is paragraph 2 mainly about?
A．Fisher’s social activities.
B．Fisher’s trips to European countries.
C．The reason for Fisher’s shooting glaciers.
D．The cause of the rise in Earth temperature.
【2】What is related to Fisher’s flying hobby?
A．His grandparents' dream.
B．His childhood experiences.
C．His curiosity for taking photos in the air,
D．His interest in seeing glaciers from the air,
【3】Which word best describes Fisher’s photographs?
A．Romantic.
B．Unattractive.
C．Confusing.
D．Valuable.
【4】What does Fisher say about his photographs in the last paragraph?
A．They lack light processing.
B．They lack the colors and shapes.
C．They show the beauty of glaciers.
D．They hardly show the loveliness of glaciers.
22、Many owners of electric cars have wished for a battery pack that could power their vehicle for more than a thousand miles on a single charge. Researchers have developed a lithium-air battery that could make that dream a reality. The new battery design could also one day power airplanes and trucks. The main new component in this lithium-air battery is a solid electrolyte (电解质) instead of the usual liquid variety.
Batteries with solid electrolytes are not subject to safety problems with the liquid electrolytes used in lithium-ion and other battery types, which can overheat and catch fire. More importantly, the solid electrolyte can potentially boost the energy four times, which translates into longer driving range.
For over a decade, scientists have been working overtime to develop a lithium (锂) battery that makes use of the oxygen in air. The lithium-air battery has the highest energy of any battery technology being considered for the next generation of batteries beyond lithium-ion.
The new solid electrolyte is composed of a material made from relatively inexpensive elements, compared with the past designs. Besides, the chemical reaction in lithium-ion only involves one or two electrons stored per oxygen molecule (分子), while that for lithium-air battery involves four electrons. More electrons stored means higher energy.
The new design is the first lithium-air battery that has achieved a four-electron reaction at room temperature. It also operates with oxygen supplied by air from the surrounding environment. The capability to run with air avoids the need for oxygen tanks to operate, a problem with earlier designs.
“With further development, we expect our new design for the lithium-air battery to reach a record of 1200 watt-hours per kilogram,” said Curtiss, a researcher. “That is nearly four times better than lithium-ion batteries.”
【1】What contributes most to the lithium-ion battery?
A．Lithium-ion.
B．Oxygen molecules.
C．Solid electrolytes.
D．Liquid component.
【2】What’s the problem with lithium-ion batteries?
A．They burn easily if overheated.
B．They are unsafe in production.
C．They damage the environment.
D．They require longer charging time.
【3】How does the author organize paragraph 4?
A．By giving examples.
B．By making comparisons.
C．By presenting statistics
D．By analyzing cause and effect.
【4】What is the best title of the text?
A．How Lithium-air Batteries Work
B．What will Be Used to Power Airplanes
C．Electric Cars Are Becoming More Popular
D．New Batteries Offer Longer Driving Range
23、 Most adults firmly believe that as kids reach their teens, they start to take crazy risks that get them in trouble. Do teenagers simply love taking all risks much more than adults? A recent study suggests otherwise.
Scientists designed a simple experiment involving 33 teenagers and three other age groups. In the experiment, the researchers tried to distinguish between two very different kinds of risk-taking. The first they called a tendency to take known risks (when the probability of winning is clear) and the second they called a tendency to take unknown risks (when the possibility of success is uncertain).
The study offered participants the opportunity to play two kinds of games. They had the chance to win money, with one game offering a known risk and the other offering an unknown risk. On each round of the game, each participant had to choose between taking a sure $5 and known or unknown risks of winning a lot more. If on one particular round they had picked the $5 for sure choice, then they got $ 5. But if on that round they had chosen to take a risk, the rules of the game will determine whether or not they had won. If they did win, they went home with between $8 and $125. And, of course, if they lost, they went home with nothing.
What the scientists found was really quite surprising. It turned out that the average teenager was very irresolute when risks were known---more careful than college students or parent-aged adults, and as careful as grandparent-aged adults. This means that when the risks were known, teenagers were not risky in their behavior at all. Only when the risks were unclear did teenagers choose them more often than other groups.
So, what does all of this mean? The research suggests that adults should probably focus more energy on trying to educate teenagers about risks than limiting them. Teenagers who understand the risks associated with a decision are more likely to be careful in their behavior.
【1】How was this experiment carried out?
A.By dividing the teens into three groups.
B.By comparing the reactions to different risks.
C.By giving equal amount of awards to the participants.
D.By observing the emotional changes of the teenagers.
【2】What does the underlined word “irresolute” in Paragraph 4 mean?
A.brave. B.intelligent. C.independent. D.hesitant.
【3】According to the study, parents should focus on _______.
A.guaranteeing children to be cautious
B.setting age limits on risky activities
C.respecting teens to make their own choices
D.guiding teens to analyze risks
24、WE COMBAT ANIMAL DISEASES TOGETHER!
We want to prevent serious animal diseases such as foot and mouth disease, classical swine fever and African swine fever from spreading to Finland. These and other animal diseases can be transmitted from one country to another by animals or by meat and dairy products even if they are packed for personal consumption or intended as gifts. Travelers like you play an important role in preventing the spread of animal diseases.
Don’t bring meat, meat products, milk and dairy products from non-EU countries to Finland!
A ban on personal imports applies to meat and dairy products brought into Finland by travelers or ordered and sent through the post. The ban applies to food stuffs intended for personal consumption or as gifts and to pet food. If you have food products of animal origin with you, throw them in a waste container in the point of entry or contact Customs!
Bringing meat-containing products as presents and for personal use from an EU country to Finland
At the moment, there are EU countries with cases of African swine fever. In those countries there are restriction areas and, as a rule, pork and wild bear meat or products containing these meats may not be imported from these areas into Finland. Import is allowed only under very strict criteria controlled by local authorities. However, the sales of these meat products within the country may be allowed. In the EU, the disease has been detected in Estonia, Latvia, Lithuania, Poland, Hungary, Romania, Bulgaria, Belgium and Italy (Sardinia), for instance. It is difficult for travelers to know and prove from which area meat products originate and whether the products on sale meet all criteria. This is the reason why we recommend that people avoid importing any meat products containing pork or wild bear meat as presents or for personal use from countries with African swine fever.
PLEASE NOTE! Never leave any food waste or leftover in the environment or places where they may be eaten by wildlife. Never give food waste or leftover to production animals or to pet pigs.
Thank you for helping us to prevent the spread of animal diseases. We wish you a pleasant journey!
