阅读理解The human body possesses an efficient defense system to battle with flu viruses. The immune system protects against the attack of harmful microbes (微生物) by producing chemicals called antibodies, which are programmed to destroy a specific type of microbe. They travel in the blood and search the body for invaders (入侵者). When they find an invasive microbe, antibodies attack and destroy any cell that contains the virus. However, flu viruses can be a terrible enemy. Even if your body successfully fights against the viruses, with their ability to evolve rapidly, your body may have no protection or immunity from the new ones. Your body produces white blood cells to protect you against infectious diseases. Your body can detect invading microbes in your bloodstream because they carry antigens in their proteins. White blood cells in your immune system, such as T cells, can sense antigens in the viruses in your cells. Once your body finds an antigen, it takes immediate action in many different ways. For example, T cells produce more antibodies, call in cells that eat microbes, and destroy cells that are infected with a virus. One of the best things about the immune system is that it will always remember a microbe it has fought before and know just how to fight it again in the future. Your body can learn to fight so well that your immune system can completely destroy a virus before you feel sick at all. However, even the most cautious people can become infected. Fortunately, medical scientists have developed vaccines (疫苗), which are weakened or dead flu viruses that enter a person's body before the person gets sick. These viruses cause the body to produce antibodies to attack and destroy the strong viruses that may invade during flu season.

The best ideas are often so smart, so simple and so clearly needed; it's strange to discover they don't already exist. So it is with Farm My School, a program that's turning underused land at secondary schools into commercially achievable, regenerative market gardens farmed by and for local communities.

Co-founded by permaculturist Ben Shaw and regenerative educator James McLennan, Farm My School connects local people and organizations through volunteering that helps establish a school's market garden. Students learn about community networks, healthy eating, ecological responsibility, waste reduction, and climate relief while helping with food production. Schools integrate all these into their courses while producing vegetable boxes every week that feed local families, supply the school's food needs and ultimately pay the farmer's salary.

Farm My School has gained the extraordinary enthusiasm of the locals, who answered an online shout-out to buy tickets to the program's launch event at Bell Secondary School last October. Called Build A Farm in a Day Festival, the event featured workshops by Ben and James to share the skills required to build what they say is the world's largest no-dig garden. "It was such a powerful event, and I think that comes down to people wanting to act now," says James. "We charged for the experience and 600 guys turned up! They didn't even need free drinks to get excited. We were gardening till midnight. It was amazing. We've got true community buy-in."

Volunteers have since begun beneficial planting throughout the school. Next steps include further discussions with local communities, employing a farmer, and bringing in a teacher to develop courses. "We've seen this huge push towards seeing schools as regenerative spaces, not just for planting but for kids to be more connected to the outside world, and really seeing the school in a whole new light," James says. "For us, the big excitement is that by allowing a professional farmer to take the responsibility of growing food, it's not only on the school to look after that farm anymore, which eventually makes it much more sustainable," adds Ben.

(1) Why was Farm My School founded? A. To raise the income of the local people. B. To advocate a commercial farming plan. C. To provide free food for local communities. D. To turn underused campus land into market gardens.

(2) How do schools involve students into the program? A. By developing program-based courses. B. By organizing voluntary work in communities. C. By offering them part-time jobs in the market gardens. D. By encouraging them to produce daily vegetable boxes.

(3) What does the underlined word "buy-in" mean in paragraph 3? A. Competition. B. Investment. C. Support. D. Protection.

(4) What is the highlight of the program according to Ben? A. It brings in money to support the school. B. The school farm will be able to last long. C. The local people will take care of the farm. D. Students connect more with the outside world.
