21、It used to be mostly the military that used small, unpiloted airplane, called “drones”. The little planes were very costly. But the fast rate of development of computer technology, image sensing devices, satellite navigation and smartphones has led to lower-priced drones. Researchers and developers have learned how to build smaller and less-costly drones sought by individuals, companies and governments.
Romain Faroux is a French businessman who starts companies. His father was a farmer. He believed drones could help farmers. He helped create a company that developed a small drone that could be controlled by people on the ground with smartphones or tablets, depending on the application of the technology of GPS. They called it “Agridrone”. It uses a special “optical sensor (光学传感器)” to examine crops. He says the technology used is similar to that used by smartphones—except it has wings.
A computer program directs the drone to fly over the crops. The sensor on the drone records four different-colored “bands” of sunlight that are reflected off the crops.
Jean-Baptiste Bruggeman, who is a farmer, says the drone flies over his crops at different times of the season, which provides a lot of information about his crops.
He says the drone pictures show him the exact amount of fertilizer (肥料) the crops need. He says it also shows exactly where the fertilizer is needed. Farmers use information gathered by the Agridrone to place fertilizer only in areas where it was needed. He says some areas of a field may need less than others. As a result, there is reduced nitrogen from the fertilizer after the harvest, which reduces pollution. Before they used the drones, farmers would put the same amount of fertilizer everywhere. He notes drones also save time because farmers can examine up to 30, 000 square metres.
【1】What used to be people’s concern of using drones?
A．Their security.
B．Their price.
C．Their size.
D．Their function.
【2】What is special for an “Agridrone”?
A．It can rely on the technology of GPS.
B．It can be controlled by smartphones.
C．It can direct its flight with an optical sensor.
D．It can examine crops and provide information.
【3】According to Mr. Bruggeman, by using drones he enjoys all the benefits EXCEPT _______.
A．saving money
B．saving time
C．helping nature
D．increasing production
【4】What is the passage mainly about?
A．A businessman built a drone for farmers.
B．Many people have begun to use drones.
C．Farmers are using drones to monitor their crops.
D．The development of technologies leads to new drones.
22、 Roger Federer, who recently became the oldest man to hold the No. 1 ranking in men's tennis at the age 36, will bring a 12-match winning streak (连胜) to the BNP Paribas Open, which starts this week at the Indian Wells Tennis Garden.
Federer, a five-time winner of the hard-court event and a 20-time Grand Slam singles champion, on Tuesday was seeded No. 1 in a field that has been given up by injuries to several excellent players. Among those missing are world No. 2 Rafael Nadal (hip injury), Stan Wawrinka (knee), who lost to Federer in the 2017 final, David Goffin (eye) and Andy Murray (hip surgery).
Federer, who has spent 305 weeks of his career at the top the Assn of Tennis Professional world rankings, must reach the semifinals (半决赛) at Indian Wells to keep his No. 1 status. If he exits sooner than that, Nadal would regain the top spot. Federer has a first-round bye (轮空) and a seemingly easy projected route to the quarterfinals, where he likely would face No. 5 seed Dominic Thiem of Austria.
Five-time Indian Wells champion Novak Djokovic, who had a small medical intervention (干预) on his troublesome right elbow earlier this year, was seeded 10th in the tournament. Djokovic has played only four matches this year because of his elbow problems and hasn't played a tournament since he lost to Hyeon Chung of South Korea in the round of 16 at the Australian Open in January.
Maria Sharapova of Russia will face Naomi Osaka of Japan on Wednesday with their match scheduled for not before 5:00 p.m.
On Thursday, Serena Williams will play Zarina Diyas of Kazakhstan and Victoria Azarenka of Belarus will play Heather Watson of the United Kingdom during the evening session (7 p.m. start).
【1】What can we infer from paragraph 2?
A. Federer gave up the match on Tuesday due to the injury.
B. Many excellent players took part in the match including Rafael Nadal.
C. Federer was lucky enough seeded No. 1 on Tuesday.
D. Stan Wawrinka beat Federer in the 2017 final.
【2】Why does Federer have a seemingly easy projected route to the quarterfinals?
A. Because he is seeded No.1
B. Because he has a first-round bye.
C. Because many excellent players are missing.
D. Because he is well enough to beat any player.
【3】Who is most likely to be the seed next to Federer among the players who can play in the BNP Paribas Open?
A. Rafael Nadal. B. Maria Sharapova.
C. Novak Djokovic. D. Dominic Thiem.
【4】What is the best tittle of the text?
A. Roger Federer, seeded No. L

D. Roger Federer, the oldest No.1
23、There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.
Food production
With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that---it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to" re-create forms and pieces" of food that are" exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.
Sustainability(可持续性)
The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids( 水解胶体)from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原 料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.
Nutrition
Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday 's bread from the supermarket, you' d eat something baked just for you on demand."
Challenges
Despite recent advancements in 3D food printing，the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste( 糊状物)before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients，because meat and milk products may easily go bad. Some experts are doubtful about food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.
【1】What benefit does 3D printing bring to food production?
A. It helps cooks to create new dishes.
B. It saves time and effort in cooking.
C. It improves the cooking conditions.
D. It contributes to restaurant decorations.
【2】What can we learn about 3D food printing from Paragraph 3?
A. It solves food shortages easily.
B. It quickens the transportation of food.
C. It needs no space for the storage of food.
D. It uses renewable materials as sources of food.
【3】What is the main factor that prevents 3D food printing from spreading widely?
A. The printing process is complicated.
B. 3D food printers are too expensive.
C. Food materials have to be dried.
D. Some experts doubt 3D food printing.
【4】What could be the best title of the passage?
A. 3D Food Printing: Delicious New Technology
B. A New Way to Improve 3D Food Printing
C. The Challenges for 3D Food Production
D. 3D Food Printing: From Farm to Table
24、I’m losing my hair. Don’t feel sorry. It will not be an explanation on how depressing it is that my body is submitting to the damages of time. It’s just a fact, and, honestly, I’m fine with it. Don’t get me wrong: had this happened when I was 25, I would have rushed to an Istanbul clinic with credit cards faster than you could say “Elton”. I would have had a baseball cap glued to my scalp (头皮). But I’m 40 now.
Hairdressers used to praise me on my “thick hair”, however, they’d make no obvious difference to my lion-like hairs. Therefore, this raises a question: why am I still spending £50 getting my hair cut? The answer to this is, I suppose, “habit”. But if the pandemic has taught us anything, it’s that even our fundamental behaviors can be transformed when necessary. For decades, I’ve frequented salons (美发厅). I enjoyed the air conditioning and the coffee. But really, all I require these days is a short back and sides. So, for the first time, I’ve started going to my local barbershop. And… it’s great! For one thing, you don’t need to book an appointment.
The two guys are friendly, yet also business-like. Best of all, the cut costs £15, and my hair looks exactly the same as when it was done in the salon. The first time my barber placed a wet towel over my nose and mouth, I’ve come to appreciate the feeling of a freshly-shaved jaw. So yes, my hair is thinning: I am older. But also, I believe, wiser.
【1】What do we know about the author from paragraph1?
A．He has a lot of credit cards.
B．He is fine with his thinner hair now.
C．He feels upset about losing his hair.
D．He likes gluing a baseball cap to his scalp.
【2】Why does the author reject the salons he’s frequented?
A．Because the salons charge too much.
B．Because he wants to change his hairstyle.
C．Because the hairdressers make his hair lion-like.
D．Because he has no habit of making appointments.
【3】What does the author think of the local barbershop?
A．Inspiring.
B．Challenging.
C．Satisfying.
D．Disappointing.
【4】What message does the author try to get through to us?
A．It’s wise to accept changes owing to aging.
B．The old are more likely to have thinner hair.
C．Crucial behaviors can be changed if necessary.
D．Salons and barbershops make no big difference.

26、阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 续写的词数应为150左右。
In 1989, fresh out of high school, I had the difficult task of choosing a career path before college started in three months. In those days in Pakistan, there were limited options: becoming a doctor or an engineer, or entering the financial world after getting a business degree. I wasn't interested in engineering, so that I was left with medicine or business. I couldn't decide.
My uncle, an influential person in the family, suggested that I do a work placement to experience it for a month in an international company followed by a month in a hospital. After that, I could make a decision. It seemed like a brilliant idea.
I was accepted for a month's placement at a foreign bank in Karachi. I got a feel for how the world of finance functioned, made new friends, and generally enjoyed the mostly easy-going work surroundings.
The month passed rapidly, and soon I began working at a leading hospital in Karachi. The experience couldn't have been more different. The hospital had an intense environment. The days started early( at 7 am, compared to 9 am at the bank), and were filled with endless duties. And the night calls! This was crazy, working all day, through the night, and again the next day.
I began thinking about my two experiences. The bank had offered a more relaxing atmosphere, better working hours and less stress. The hospital was full of excitement and unpredictability, but the studying and training was difficult. It seemed that the business option was going to win out.
Near the end of my month at the hospital, I was driving home after an especially busy night call. In front of me was a public bus, with college students sitting on the top. As the driver weaved through (穿梭) traffic, I could see the boys shaking from side to side.
Paragraph 1:
Suddenly, a boy fell off the back of the bus.
______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
Paragraph 2:
The next day, when I went to hospital to see the boy, all his family got up, with grateful smiles on their faces.
