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

14、s placed in hard-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 Fis

15、h and Wildlife 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

16、 among those using 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 provi

17、de information 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. Scientist

18、s do not know if 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 researchi

21、btful.B.Positive.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

22、 intelligence, 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

23、 a farm. The robot 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. I

24、t uses the same 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 i

25、s because the system 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 sy

26、stem called See & 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 busine

27、ss development 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 examp

28、les of pigweedand 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 reco

29、gnition technology.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 v

30、arious plants.4.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.

Plastica widely-used materialhas in

32、 many ways been 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 pe

33、rcent of the garbage 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 b

34、e poisonous to 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

35、 thinking twice 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 ne

36、ed to do their 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

37、miles in more than 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

38、time, but at a 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

39、 fingers. Mobile 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 . Pe

40、rhaps the days 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 ge

41、ntler pace. There 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 .

It was wet and trembling. At first it was difficult to see the little one. It was the yellow spots on its eyes t

51、hat made me realize 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.
