Have you ever wondered whatwild animals do when no one is watching? Low cost, dependable and small modern cameras offered a big help. Cameras placed in har

14、d-to-reach places have shot everything from small desert cats to larger snow-loving felines in the northern Rocky Mountains. Scientists have been able to document the private moments of wildlife with leading technology. Grant Harris is a government biologist with the United States Fish and Wildlife

15、Service in Albuquerque, New Mexico. In his words, theres no doubt that these wild cameras are important tools to learn new information on wildlife. Harris said some images help scientists see the effects of climate change. Researchers with the Wyoming Migration Initiative, or WMI, are among those us

16、ing wild cameras along with global positioning systems, or GPS. But WMI director Matthew Kauffman says as those devices are limited, so is the amount of information they can gather from GPS. However, cameras can be left in very wild areas for days, weeks or even months. They can provide information

17、on how many animals are moving over a given period of time. Putting those cameras in place requires careful planning. Wild video can show details about animal behavior. However, wild cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know i

18、f the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way. Even with such problems, wild cameras are clearly an important scientific tool in researching wild animals

21、e.C.Uncertain.D.Uncaring.4. Nearly every week, we hear news about the latest successes and failures in driverless vehicles. But we hear little about how other industries are developing this same kind of technology. One industry heavily involved in researching and developing artificial intelligence,

22、or AI, is agriculture. Companies are experimenting with high-tech tools that can help farmers save time and money, while reducing environment-harming chemicals. One of the companies is ecoRobotix of Switzerland. It created a robot equipped with AI and cameras to identify all plants on a farm. The ro

23、bot has four wheels to carry it through the fields in search of weeds. Computer-controlled arms then lower and spray the weeds with small amounts of herbicide (除草剂). Company officials say the robot can fully operate on its own for up to 12 hours a day while being powered by the sun. It uses the same

24、 kind of sensor and positioning technology used to guide driverless vehicles. A farmer can also control the equipment through a smartphone. The co-founder of ecoRobotix, Aurelien Demaurex, says the farm robot can kill weeds with 20 times less herbicide than traditional methods. This is because the s

25、ystem uses exactly the right amount of chemical in the exact place required to kill the weeds. Currently, farmers spread weed killers over massive areas to destroy unwanted plants. Another company developing farm robotics is California-based Blue River Technology. The company has a system called See

26、 & Spray, which it claims is the worlds first smart sprayer. The systemwhich connects to the back of a tractoris also equipped with AI to identify and chemically kill only the weeds. It can also spray chemicals on wanted plants to help them grow. Ben Chostner, vice-president of business development

27、for Blue River Technology, explains in a company video that See & Spray technology uses the same deep learning methods used in facial recognition. The first time the machine saw a pigweed, it didnt know what kind of plant it was. But we taught itby giving it tens of thousands of examples of pigweeda

28、nd now its an expert in pigweed.1.How will AI benefit agriculture?A.It will fund agriculture research.B.It contributes to low-cost farming.C.It can avoid harmful chemicals.D.It frees all farmers from field work.2.What do the products of the two companies have in common?A.They use recognition technol

29、ogy.B.They are powered by solar energy.C.They are connected with smart phones.D.They can help wanted plants grow rapidly.3.What do Ben Chostners words suggest about the robot?A.It is environmentally friendly.B.It is good at self-improving.C.It has the learning ability.D.It can track various plants.4

30、.What is mainly talked about in the text?A.The experiment in farming robots.B.New trend in artificial intelligence.C.Modern See & Spray technology.D.Artificial intelligence in agriculture.二、七选五 Imagine an area 34 Limes the size of Manhattan. Now imagine it covered ankle-deep in plastic wastea total

31、of about 19 billion pounds of garbage. _ Were being overwhelmed (淹没) by our waste, said Jenna Jambeck, an environmental engineer who led the 2015 study that determined this astonishing number. _, unless something is done to stop the tide of garbage. Plastica widely-used materialhas in many ways been

32、 a benefit to humans but it has also caused a growing problem. Today, plastics are the No. 1 type of garbage found in the sea. Ocean Conservancy, a nonprofit environmental advocacy group that organises an annual coastal cleanup event worldwide, said plastic waste makes up around 85 percent of the ga

33、rbage collected from beaches and oceans. Ocean Conservancy says plastics are believed to threaten (威胁) at least 600 different wildlife species (物种). _; a growing body of evidence suggests humans are consuming plastics through the seafood we eat. Research suggests some plastics could be poisonous to

34、humans, and could potentially increase the risk of health problems. _. At the Economist World Ocean Summit this week, ten nations announced to reduce plastic sea litter as part of UN Environments Clean Seas campaign. _. Corporations also have a role, as do individuals. We can start by thinking twice

35、 before using single-use plastic productsand when we do use them, we should take care to properly throw them off or recycle.A.The following is what we should doB.And its not just wildlife thats threatenedC.And this figure is likely to double by 2025D.But its not just countries that need to do their

36、partE.By 2050, that figure is expected to rise to 1,000 piecesF.Thats how much plastic waste ends up in our oceans every yearG.All of us have an important role to play in dealing with the problems三、完形填空 Modern inventions have speeded up peoples lives amazingly. Motor cars 1 a hundred miles in more t

37、han an hour, aircraft cross the world within a day, while computers operate at lightning speed. Indeed, this love of 2 seems never-ending. Every year motor cars are produced which go even faster and each new computer boasts (吹嘘) of 3 precious seconds in handling tasks. All these save time, but at a

38、cost. When we lose or 4 half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling known as jet-lag (时差). Our bodies feel that they have been 5 behind in another time zone. Again, spending too long at 6 results in painful wrists and fingers. Mobil

39、e phones also have their dangers: too much use may transmit harmful 7 into our brains. However, how do we 8 the time we have saved? Certainly not relax, or so it seems. We are so used to constant activity that we find it 9 to sit down and do nothing or even just one thing at a 10 . Perhaps the days

40、are long gone when we might listen 11 to a story on the radio, letting imagination take us into another world. There was a time when some peoples lives were devoted simply to the cultivation (耕作) of the 12 or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace. The

41、re is much that we might envy about a 13 of life like this. Yet before we do so, we must think of the hard tasks our ancestors 14 .

49、 was seven years old. My dad had just got a new job in Nasik. We had moved into a rented house. It was raining very heavily on the day we moved. It was a cold dark night. We had our meal and went to sleep. Somehow in the midnight I heard some strange sounds outside the main door. I gathered courage

50、and looked out through the window and I was really amused with what I saw outside. There was a small puppy lying on an old doormat which my mother had put outside the door. It was wet and trembling. At first it was difficult to see the little one. It was the yellow spots on its eyes that made me rea

51、lize its presence. It was trying to get under the doormat to avoid the cold air outside and it had managed to get in as I could see only its head outside the doormat. Was it sick or injured? I felt pity for the poor soul. I went in and came out with an old towel. I went near the innocent one and hel
