There are only a few truly pleasant smells to wake to in the morning. For me, it's the smell of freshly brewed coffee. Just a sniff of it makes me jump out of bed and rush to the kitchen for a gulp of the hot black liquid.
If you're a big fan of coffee, you'll understand that opening a new packet of coffee releases an amazing smell—fresh, roasted coffee beans. And you'll be able to identify the beans' origin—Colombia, Vietnam or Brazil. Tim Hayward is a food writer and coffee shop owner; he believes the smell is absolutely vital. “When you walk into the coffee shop in the morning and that smell hits you, you're getting physiological responses. ”
I know from experience when I walk into a cafe, my mouth begins to water and it's the smell that makes me feel good. However, this feeling sometimes turns to disappointment. This is particularly the case when I order a coffee to go in a tall paper cup and sip the liquid through a hole in the lid. Yes, it's convenient, but is it really the right way to appreciate it?
You walk into the coffee shop, you get the smell, but when you actually take the drink out, you are drinking it from something that is designed to deliver the hot liquid directly past your tongue, but prevent any smell coming up to your nose. As well as eliminating the smell, takeaway coffee cups create a lot of waste and the vast majority of them still don't get recycled. So maybe now is the time to really wake up and smell the coffee by drinking from a cup in a care, chatting with friends and saving the planet!
1．In which aspect does the author agree with Tim Hayward? A．People drink coffee first thing in the morning. B．Coffee beans' origin makes all the difference. C．Some people are addicted to drinking coffee. D．It's the smell of coffee that really matters. 2．What does the author complain about? A．The process of making coffee. B．The high temperature of coffee. C．The design of the paper coffee cup. D．The inconvenience of buying coffee.
3．Which can replace the word “eliminating” underlined in Paragraph 4? A．Creating. B．Removing. C．Increasing. D．Changing.
4．What can be the best title of the text? A．Wake up and smell the coffee B．Try to be a real lover of coffee C．Drink coffee to save the planet
D．Choose takeaway coffee for convenience

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, 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 robot has four wheels to carry itself 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 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, Aurélien Demaurex, says the farm robot can kill weeds with 20 times less herbicide than traditional methods. This is because the system uses exactly the right chemical amount 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 & Spray”， which it claims was the world's first smart sprayer. The system—which is connected to the back of a tractor—is 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 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 pigweed, it didn't know what kind of plant it was. But we taught it—by giving it tens of thousands of examples of that pigweed—and now it's an expert in pigweed.”
5．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.
6．What do the products of the two companies have in common? A．They use recognition technology. B．They are powered by solar energy. C．They are connected with smartphones.
D．They can help wanted plants grow rapidly.
7．What do Ben Chostner's 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.
8．What is mainly talked about in the text? A．The experiment in farming robots.
B．A new trend in artificial intelligence. C．Modem See & Spray technology.
D．Artificial intelligence in agriculture. Ⅱ.语法填空
