A 27-year-old inventor, Joco Paulo Lammoglia, has come up with a new device named the AIRE mask, which is capable of converting the wind energy provided by the wearer’s breath into electrical energy. This means breathing has become a source of renewable energy. The inspiration for the invention came from his watching children blowing on pinwheels (纸风车).
The device is worn like a mask equipped with tiny wind turbines (涡轮) and it can work its magic even while people are sleeping, jogging or hanging around, since energy is created from one’s breath. The principle of this AIRE mask is simple. The invention uses the wind flow created by breathing and changes it into energy that can charge mobile phones and iPods. Simply put this mask connected to your mobile phone on your face. The rest takes place naturally through your breath that provides power to run turbines which produce electricity.
Lammoglia explained how useful he hopes the AIRE will become. He said, “I hope to bring the concept into production and reduce the carbon footprint. It can be used indoors or outdoors, while you’re sleeping, walking, running or even reading books.” Apart from saving energy and contributing to environmental protection, it also encourages the practice of physical exercise. This is an entirely all time renewable energy source. Its energy is available 24 hours a day, seven days a week.
Lammoglia explained why he thought the AIRE was so useful, saying, “Though many of our modern devices offer benefits, they tend to consume a high amount of electrical energy. This may cause problems for the environment, especially if the energy used by these devices is obtained from non-renewable sources.
The AIRE mask will be future’s cheaper source of charging mobile phones. It would save energy and allow people to never have to worry about their phone dying unless they stop breathing.
1.The word “converting” (para.1) is closest in meaning to _______.
A. charging B. convincing
C. exchanging D. transforming
2.After putting on the mask, how do people charge their mobile phones using the device?
A. Breathe out air-Drive turbines-Produce electricity.
B. Use wind-Pass through turbines-Produce electricity.
C. Breathe in air-Use turbines-Create energy.
D. Connect turbines-Produce wind flow-Create energy.
3.Lammoglia would most probably agree that the AIRE mask _______.
A. consumes a high amount of energy
B. will account for environmental damage
C. is a good solution to energy issues
D. is available in the shop now
4.Which of the following is the best title for the passage?
A. An electronic mask B. A breath-powered charger
C. A new renewable energy source D. An air purifying device

A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct (不同的) species
The discovery was made by researchers at York and Harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants—the Asian elephant, African forest elephant and African savanna elephant
Once they obtained DNA sequences (序列) from two fossils (化石)，mammoths and mastodons the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths.
The scientists used detailed genetic analysis to prove that the African savanna elephants and the African forest elephants have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists.
There has long been debate in the scientific community that the two might be separate species but this is the most convincing scientific evidence so far that they are indeed different species.
Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species despite the elephants’ significant size differences. The savanna elephant has an average shoulder height of 3.5metres while the forest elephant has an average shoulder height of 2.5metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However, the proof lay in the analysis of the DNA.
Alfred Roca, assistant professor in the department of Animal Sciences at the University of Minois, said, “We now have to treat the forest and savanna elephants as two different units for conservation purpose. Since 1950 all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinct animals, the forest elephant should become a bigger priority (优先)for conservation purpose .”
1.One of the fossils studied by the researchers is that of ________.
A. the Asian elephant B. the forest elephant
C. the savanna elephant D. the mastodon elephant
2.The underlined word “divergence” in paragraph 4means “________”
A. evolution B. exhibition C. separation D. examination
3.The researcher’s conclusion was based on a study of the African elephant’s ____________
A. DNA B. height C. weight D. population
4.What were Alfred Roca’s words mainly about?
A. The conversation of African elephants.
B. The purpose of studying African elephants
C. The way to divide African elephants into two units
D. The reason for the distinction of African elephants
5.Which of the following can be the best title for the passage?
A. Naturalist’s Belief about Elephants.
B. Amazing Experiment about Elephants
C. An Unexpected Finding about Elephants
D. A Long scientific Debate about Elephants

Since I moved to Seattle, there’s no farm whose name has come up more than Quillisascut. Quillisascut is a cheese company, 36 what they call “traditional farmstead cheese’’, but it’s also a school. 37 completing a five-day “Introduction to Farming” workshop at Quillisascut, I understand why this farm school is so 38 . I hope that you can one day visit it, too.
At Quillisascut, mornings begin at 5:30 am with 39 and milking the goats. The morning’s 40 is made into cheese in the afternoon. Cheese making requires many steps. The process can take one day to several months, 41 the type of cheese being made.
During our workshop, we were lucky enough to have the farm’s chefs 42 meals of grains and beans from neighboring farms and herbs from the garden. All of the foods used for cooking are either grown there or 43 sourced.
Any 44 from meals is made into compost(堆肥). It is 45 onto the farm’s land, transforming Quillisascut’s soil 46 fertile salad bars for the goats. In addition to sunlight, rain, and compost, the goat farm 47 seeding and reseeding.
When I know where my food came from, who 48 it, and the complex process it took to get to my 49 , food does more than fuel my body. It also heats my 50 . I wonder how different our food and healthcare systems would look like if all people learnt firsthand about the 51 and tears involved in bringing food to the table.
If every food production operation 52 the public onto its ground, it is possible that our country’s food system would look very different; and our country’s connection with food could 53 .

You get anxious if there’s no wi-fi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power and you secretly worry things will go wrong at work if you’re not there. All these can be called “always on” stress caused by smart phone addiction(上瘾).
For some people, smart phones have freed them from the nine-to-five work. Flexible working has given them more autonomy (自主权) in their working lives and enabled them to spend more time with their friends and families. For many others, though, smart phones have become cruel masters in their pockets, never allowing them to turn them off and relax.
Pittsburgh-based developer Kevin Holesh was worried about how much he was ignoring his family and friends in favor of his iPhone. So he developed an app — Moment — to monitor his usage. The app enables users to see how much time they’re spending on the device(设备) and set up warnings if the usage limits are broken. “Moment’s goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”
Dr. Christine Grant, an occupational psychologist at Coventry University, said, “The effects of this ‘always on’ culture are that your mind is never resting, and you’re not giving your body time to recover, so you’re always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”
And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis (瘫痪) and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they’re controlled by it all and feel they can never escape the office,” said Dr. Christine Grant.
1.What’s the first paragraph mainly about?
A. The popularity of smart phones.
B. The progress of modern technology.
C. The signs of “always on” stress.
D. The cause of smart phone addiction.
2.Kevin Holesh developed Moment to_______.
A. research how people use their mobile phones
B. help people control their use of mobile phones
C. make people better use mobile phones
D. increase the fun of using mobile phones
3.What’s Dr. Christine Grant’s attitude towards “always on” culture?
A. Confused. B. Positive.
C. Doubtful. D. Critical.
4.According to the last paragraph, a greater amount of data means_______.
A. we will become less productive
B. we can make a decision more quickly
C. we will be equipped with more knowledge
D. we can work more effectively
