In 2011, during his freshman year at the University of Maryland, Simon was struck by how much food was thrown away in the college cafeteria. I was shocked to see someone buy a full sandwich, eat half of it, and throw the other half out, sa

2、id Simon. It was not the value I grew up with. For him, discarded food was a natural goldmine where he could source to do good. Four years later, Simon co-founded Imperfect Produce, a subscription-based home-delivery service for discounted ugly fruits and vegetables that are perfectly good on the in

3、side, but otherwise rejected from the food supply chain for their looks. Up to 20% of the fruits and vegetables grown on farms in America are thrown away because the produce doesnt meet grocery stores standards, said Simon. Its often for discoloration, scarring on the surface caused by the fruit rub

4、bing against a tree limb or an atypical shape, he said. Sometimes its the size. Simon, 29, and Chesler, 27, decided to source this ugly produce directly from farms and deliver it to customers for about 30% less than conventional grocery store prices. The reason why we created Imperfect Produce as a

5、direct-to-consumer business is because grocery stores didnt want to partner with us, said Simon. So we became our own store. The San Francisco-based service launched in August 2015. Today, Imperfect Produce has more than 200, 000 subscribers in 22 cities. The company sources its produce from 250 gro

6、wers nationwide, and slightly more than half of it is organic. To date, Simon said the service has helped recover 40 million pounds of food from going to waste.

A facial recognition app will make it easy for you. The app is developed by the Chengdu Research Base of Giant Panda Breeding along with resear

10、chers in Singapore Nanyang Technological University and Sichuan Normal University. You no longer need to worry about making the pandas angry by calling them by the wrong name, the Chengdu Research Base of Giant Panda Breeding wrote on Weibo, as it announced its new giant panda facial recognition app

11、. Visitors to the panda base in Chengdu, capital of Sichuan, will be able to scan the pandas face with the mobile app to get information about that particular bear. Its good news for those with face blindness for giant pandas. The image analysis research kicked off in 2017. A database now contains a

12、bout 120,000 images and 10, 000 video clips of giant pandas. Close to 10,000 panda pictures have been analyzed, marked and annotated (注释).Using the database, researchers are able to carry out automatic facial recognition on panda faces to tell one animal from another. Its not just a gimmick (噱头)for

13、tourists, though. Researchers say the technology will help them analyze data on pandas both in captive and the wild. The app and database will help us gather more precise and well-rounded data on the population, distribution, ages, gender ratio, births and deaths of wild pandas, who live in deep mou

14、ntains and are hard to track, said an expert.

Like people, plants experience stress. And also, like people, the response to that stress can determine success

17、. Bad environmental conditions, such as drought, flood, heat and other stresses, affect yields(产量) more than crop pests and diseases. We are trying to find a way to equip plants with the ability to tolerate environmental stress and maintain high yields, said Stephen Howell, a professor of genetics a

18、nd cell biology. Plant cells produce proteins (蛋白质) and ship them to different parts of the cell. Under normal conditions, these proteins are folded into their normal, healthy structures as they are produced. When a plant is under stress, its cells produce poorly folded or unfolded proteins. Then a

19、built-in system senses this and sets off an alarm in the cell, said Howell. In response to the alarm, another protein (IRE1) starts working and creates a different process which activates (激活) the stress response genes whose products bring about defensive measures that help the plant survive. As it

20、turns out, responses that are activated under stressful conditions actually inhibit the growth of plants, said Howell. This allows them to preserve their energy to survive the stressful conditions. For plants in the wild, this response is a help for survival, he said. In production of agricultural c

21、rops, however, this response reduces yields. You dont want crop plants to stop growing, Howell said. You want them to continue to grow and produce more even though they are under stress. With the new understanding of this stress response, the next step may be to silence the alarm system, said Howell

22、. What may be important is to disable some of these stress responses. That may make the plant more productive under stressful conditions.1.According to the text, an alarm in the plant cell is caused by _.A.the folded proteinsB.the changed proteinsC.the defensive measuresD.the stress response genes2.

23、The energy preserved in the plants under stressful conditions _.A.helps the plants to surviveB.helps to maintain high yieldsC.keeps the plants growingD.helps to produce proteins3.The underlined word inhibit in Paragraph 5 can be replaced by _.A.preventB.startC.continueD.promote4.How does Howell inte

24、nd to make crop plants maintain high yields under stressful conditions?A.By making crop plants keep more energy.B.By making crop plants stop growing.C.By making the alarm system stop working.D.By making the alarm system respond quickly.4. The meaning of the word volunteer may be a little different i

25、n different countries, but it usually means one who offers his or her services. There are many different ways in which people can volunteer, such as taking care of sick people, working in homes for homeless children, and picking up garbage from beaches and parks. Volunteers may work within their own

26、 countries or in other countries. They are often people with a strong wish to help those who are less fortunate than themselves. Volunteers dont expect any kind of pay. At the root of volunteering is the idea that one person may have the ability to offer services that can help other people. Tracy, a

27、 good friend of mine, however, recently came back from India with a new idea of what being a volunteer means. She worked for two and a half weeks in one of Mother Teresas homes in Calcutta. The following is her story. I first heard about Mother Teresa in my high school. We watched a video about her

28、work in India and all over the world. I was so moved by her spirit to help others and her endless love for every human being that after I graduated from high school, I also wanted to try her kind of work. So with two friends, I flew to Calcutta for a few weeks. I was asked to work in a home for sick

29、 people. I helped wash clothes and sheets and passed out lunch. I also fed the people who were too weak to feed themselves and tried to cheer them up. I felt it was better to share with them than to think that I have helped them. To be honest, I dont think I was helping very much. It was then that I

30、 realized that I had not really come to help, but to learn about and experience another culture that helped improve my own understanding of life and the world.1.According to the text, what does a volunteer refer to?A.A person who is willing to help those in need without pay.B.A person who can afford

31、 to travel to different places.C.A person who has a strong wish to be successful.D.A person who has made a big fortune in life.2.Why did Tracy choose to be a volunteer?A.She liked to work with Mother Teresa.B.She had already had some experience.C.She was asked by Mother Teresa.D.She wanted to follow

32、 Mother Teresas example.3.What is Tracys new idea (in Paragraph 2) of being a volunteer?A.Going abroad to help the sick.B.Working in Mother Teresas home.C.Doing simple things to help the poor.D.Improving oneself through helping others.4.What is the best title for the passage?A.How to Be a VolunteerB

33、.Voluntary Life in IndiaC.A Different Meaning of VolunteerD.Inspiration from Mother Teresa二、七选五 Many countries have traditional dishes, made with special ingredients and prepared in a certain way. _, and when tourists visit, these are the foods they want to try. But why are some foods more popular t

34、han others in certain areas? Traditional ingredients Typical recipes (食谱) are usually made with native plant and animal products. For example, Chinese dishes often include rice and soybeans because both plants are native to East Asia and grow well in hot, wet areas. In contrast, wheat grows well in

35、drier areas, like the Middle East, where bread is a common staple food. _, whereas inland cuisines tend to use more meat from farm animals. Food preservation Local cuisines often depend on how people traditionally prepared food for storage. In warm weather, meat and fish can go off quickly, so they

36、must be cooked right away or preserved for later._ For that reason, modern Norwegian cuisine includes many smoked foods. Cooking techniques_. In China, people often fry food in a deep metal pan or steam it in a basket over hot water. InMorocco, people cook traditional dishes in a special pot called

37、a tajine. And some local dishes arent cooked at all. Imported (进口的) ingredients Sometimes local cuisines include ingredients that originally came from another place. _, while many Russian dishes are made with potatoes. However, all of these ingredients were brought to Europe from South America in th

38、e fifteenth and sixteenth centuries. But now they are common around the world.A.Seafood is often a key ingredient in coastal areasB.There is a danger that local food traditions will be lostC.Many different cooking techniques are used around the worldD.For example, Italian dishes often include tomato

39、es and peppersE.These local dishes can become symbols of a place and its cultureF.Nowadays, we can buy food products from all around the worldG.In Norway, the Vikings used to cure meat and fish by smoking them over a fire三、完形填空 When I was a college student, I did a lot of traveling abroad. That was

40、because a professor 1 me to do so. She said, To travel around the world can 2 your knowledge through actual experiences and make you have fun. I 3 her. Since I started to work for a 4 company, however, I have done most of my traveling through the Internet. With the help of the Internet, I have also

41、got 5 about food in different countries. Therefore, I was beginning to feel that actual trips were 6 necessary until I happened to read a famous chefs comment on the Internet. He said, When we enjoy food and the 7 around us at the same time, why dont you fly over to Italy and enjoy real Italian 8 ?

42、Those words reminded me of my 9 advice. As information technology 10 , you might be able to do it without making a real trip. But this also means that you will miss the various 11 you can get from traveling. Today there are people who 12 direct communication with others and spend much of their time

43、on the Internet. It is not surprising to see a group of people 13 not with each other but into their microphones. However, we should never let it 14 our time for face-to-face communication.

47、he earth. In 1962, Rachel Carsons bestselling book Silent Spring created an _ (aware) of the dangerous effects of pesticides (农药).
