Pigeons inLondonhave a bad reputation. Some people call them flying rats. And many blame them for causing pollution with their droppings. But now the birds are being used to fight another kind of pollution in this city of 8.5 million.
“The problem for air pollution is that it’s been largely ignored as an issue for a long time,” says Andrea Lee, who works for the London-based environmental organization Client Earth. “People don’t realize how bad it is, and how it actually affects their health.”London’s poor air quality is linked to nearly 10,000 early deaths a year. Lee says, citing(引用)a report released by the city manager last year. If people were better informed about the pollution they’ re breathing, she says, they could pressure the government to do something about it.
Nearby, on a windy hill inLondon’s Regent’s Park, an experiment is underway that could help—the first week of flights by the Pigeon Air Patrol. It all began when Pierre Duquesnoy, the director for DigitasLBi, a marketing firm, won a London Design Festival contest last year to show how a world problem could be solved using Twitter. Duquesnoy, fromFrance, chose the problem of air pollution.
“Basically, I realized how important the problem was,” he says. “But also I realized that most of the people around me didn’t know anything about it.” Duquesnoy says he wants to better measure pollution, while at the same time making the results accessible to the public through Twitter.
“So”, he wondered, “how could we go across the city quickly collecting as much data as possible?” Drones were his first thought. But it’s illegal to fly them overLondon. “But pigeons can fly aboveLondon, right?” he says. “They live—actually, they are Londoners as well. So, yeah, I thought about using pigeons equipped with mobile apps. And we can use not just street pigeons, but racing pigeons, because they fly pretty quickly and pretty low.”
So it might be time for Londoners to have more respect for their pigeons. The birds may just be helping to improve the quality of the city’s air.
4. What can we infer aboutLondon’s air quality from Paragraph 2?
A. Londoners are very satisfied with it.
B. The government is trying to improve it.
C Londoners should pay more attention to it.
D. The government has done a lot to improve it.
5. Duquesnoy attended the London Design Festival to _________.
A. entertain Londoners.
B. solve a world problem.
C. design a product for sale.
D. protect animals like pigeons.
6. Why did Duquesnoy give up using drones to fly acrossLondon?
A. Because they are too expensive.
B. Because they fly too quickly.
C. Because they are forbidden.
D. Because they fly too high.
7. Which can be the best title for the text?
A. Clean air inLondon.
B. London’s dirty secret.
C. London’s new pollution fighter.
D. Causes of air pollution inLondon.
C
A cheap printed sensor could transmit wildfire warnings. Wildfires have recently destroyed regions across the world, and theirgravityis increasing. Hoping to reduce harm, researchersled by Yapei Wang, a Chinese chemist ofRenminUniversity, say they have developed an inexpensive sensor to detect such fires earlier with less effort.
Current detection methods rely heavily on human watchfulness, which can delay an effective response. Most wildfires are reported by the general public, and other alerts come from routine foot patrols and watchtower observers. Passing planes and satellites also occasionally spot something, but “the fire first appears on the ground," Wang says. “ When you see the fire from the sky, it is too late. ”
The team says its new sensor can be placed near tree trunks' bases and send a wireless signal to a nearby receiver if there is a dramatic temperature increase. That heat also powers the sensor itself, without replacing batteries. The team printed the substances onto ordinary paper to create a sensor for just $ 0.40.
But improving coordination among the different agencies involved in firefighting is even more crucial to address, says Graham Kent, an earthquake expert at theUniversityofNevada,Reno, who was not part of the study.Kentis director of ALERTWildfire, a network that uses cameras and crowd sourcing to watch for fires inCalifornia,NevadaandOregon. “The whole way that you respond to a fire until it's put out is like a ballet," he says. “You'd have to choreograph (设计) it just so, with resources precisely used at the right time and place and in the
right order from detection to confirmation to assignment to extinguishment (熄灭).Fire detection is just step one.
Wang says his team's next steps are to extend the device'ssignal range beyond the current 100 meters, which can limit practical use, and to develop a protective shield for it. The transmitter's effectiveness, he notes, will also need to be examined in the field ahead.
8. What does the underlined word “gravity” in paragraph 1 probably mean?
A. Pull.
B. Extinction.
C. Popularity.
D. Severity.
9. What do we know about the sensor?
A. Its price remains high.
B. Its batteries are replaceable.
C. It can detect fires earlier and easier.
D. It can reduce firefighters' pain.
10. What doesKentmean in paragraph 4?
A. Firefighting is easy but crucial.
B. Fire detection resources are rich.
C. Putting out a fire is an orderly activity.
D. Technology is the key to extinguishing a fire.
11. What's the plan for the new sensor according to Wang?
A. Improving and testing it.
B. Limiting its use and transmission.
C. Examing and reducing its signal range.
D. Getting it on the market ahead of time.
D
Remember when your mom told you not to eat too many candy bars or sweets because they can cause tooth decay (蛀牙)? However, it turns out that chocolate can be moresalutaryto your teeth than you might expect. Recent studies show that chocolate can effectively fight against tooth decay, as if we need another excuse to eat chocolate.
Chocolate offers protection like fluoride, a main ingredient in most household toothpastes. Not only does chocolate protect our teeth, but it can do so very effectively. Studies show that chocolate has compounds that provide strong protection for teeth. One of the compounds in chocolate, CBH, is shown to protect even more
effectively than fluoride.
Tooth decay happens when bacteria work to turn sugar into acids in our mouth. This is why eating foods with high sugar content can lead to more tooth decay. The compounds in chocolate, however, are anti-bacteria and can fight against bacteria in your mouth. The CBH compound in particular also works to strengthen tooth enamel (牙釉质), andprotects against tooth decay.
Does this mean you can cat as much chocolate as you want without worrying about your teeth? It depends on the types of chocolate that you like. The protective effect of chocolate is most effective when you chew on cocoa beans. Of course, this option is not very appealing to; most people. A more tasty option is to choose dark chocolate with little sugar content, ideally no more than 6 to 8 grams per serving. For other types of chocolate with higher sugar content, the effect will be lessened. However, because of the protective compounds, it is still better for your teeth than other sweets and desserts containing the same amount of sugar.
12. The word “salutary” in paragraph 1 means?
A. Beneficial.
B. Harmful.
C. Familiar.
D. Useless.
13. What can we know about the compound CBH in chocolate?
A. It can help chocolate cure tooth decay.
B. It can effectively stop teeth from decaying.
C. It may protect teeth better than toothpastes do.
D. It may soon replace most household toothpastes.
14. How does chocolate fight tooth decay?
A. By breaking down acids.
B. By building up compounds.
C. By fixing up tooth enamel.
D. By fighting against bacteria.
15. What's the main idea of the text?
A. Chocolate plays the role of toothpaste.
B. Chocolate protects against tooth decay.
C. Chocolate is the best choice for teeth protection.
D. Chocolate is healthier to teeth than other sweets.

When I first got the bird, it must have only just been hatched. Its mother had disappeared, leaving it alone and shivering in the face of the north wind. I decided to take it straight back and build it a new home.
At that time we grew a great many flowers in our house. Next to one hanging orchid (兰花) I hung another empty flowerpot and it was in this pot that the bird was to have its new home. When Dad got home, he immediately discovered the new addition to our family. Without saying a word, he turned around and left the house. After some time, he returned and I saw that he had a handful of grass and pine needles. Obviously, Dad thought the nest I had made was far too rough and so he had decided to decorate it himself.
“A bird born at this time of year won't survive the winter.” In spite of this prediction on the bird's future, Dad very carefully fashioned the nest himself. Soon I found “Nuo Nuo” (Dad had named him) had started to grow feathers. They looked like such fine little hairs that you could only notice them if you looked really closely. I only discovered them because every day I would cup him in my hands and look at him.
Dad probably realized that he had been a little cruel in his prediction. You see, he had already started training Nuo Nuo to walk. As you know, Nuo Nuo lived in a flowerpot, not a cage or anything. When he had nothing else to do, he walked around his little home. There were times when he was a bit naughty too and he jumped down onto our dining table.
注意：1.续写词数应为150左右。

2.请按如下格式在答题卡的相应位置作答。

It was obvious that Nuo Nuo didn't realize he was a bird.
