24．A few weeks ago，I sat with a California farmer named Dave Ribeiro.I asked him what he wished to know about farmers.He smiled and said， "We walk among you.We look like you and talk like you.We have advanced degrees and hobbies
Take Dave for example：He's a young man with a degree in music.And if you walk past him in the street，you'll never think， "There goes a farmer."
Is there someone who you picture like Dave when you think of a farmer？Probably not.I think that most people would picture a man in his overalls（工装服）.I can tell you that it does not represent Dave or any of other farmers I have gotten to know.
Not only do we have to throw out our previous impression of farmers，but farming as a whole doesn't look much like what it used to be either.We recently sent a team out to see what modern farming looks like，and they found farmers to be completely different from our usual ideas about them and also came across them in some unexpected places.
In a parking lot in a neighborhood of Brooklyn，they met a new crop of young farmers who were trying to bring fresh greens closer to eaters in the city by growing them in high﹣tech indoor vertical（垂直的） farms.In a Florida field under the fight path of an airport，they observed how farmers were using technology to take the best possible care of their animals.
These farmers all spend their days in very different ways—none of them looks like the previous farmer we have in our mind—but they're all working in new ways to feed our planet.Not only do we need to change our idea of what farming looks like，but we also need to change our view of where solutions can come from.Feeding all of us is going to take all of us working together.
（1）How does Dave describe today's farmers？ 　 　
A.They often walk in the street.
B.They are leading a very busy life.
C.They are similar to ordinary people.
D.They have little time to make friends.
（2）How does the author think most people see farmers？ 　 　
A.They usually wear overalls.
B.They have interesting hobbies.
C.They are skilled at growing crops.
D.They know modern farming practices.
（3）What is the purpose of the team？ 　 　
A.To deepen connections among farmers.
B.To study different technologies in farming.
C.To find the new developments of modern farming.
D.To encourage farmers to use the new farming method.
（4）What do the farmers mentioned in Paragraph 5 have in common？ 　 　
A.They all work in the city.
B.They all use high technology.
C.They all do hard physical work.
D.They all work with universities.
Ⅱ.七选五
25．Is there a link between social media and depression？Does social media have a negative impact on your mental health？It's complicated.
In a recent study，the investigators compared social media use and depression among teens.
（1）　 　Specifically，for every hour per day that one teen spent on social media more than his peers，he likely had a 0.64 point higher the depression score.
A different study published in 2018 identified five distinct types of social media users.The finding was that "problematic social media use" was one of the main themes for people whose mental health was affected by social media.You can have alcohol in your life without it being a problem，or your alcohol use may become problematic.（2）　 　
There's one important thing to remember about survey research—two things happen together，and it's not necessarily true that one causes the other. （3）　 　For all we know，it could be that people who are already more depressed choose to spend more time on social media.
（4）　 　If you think that we shouldn't paint social media with one broad brush，you're on the right track.On the one hand，participants often described social media as a valuable way to cope with stress.On the other hand
It's certainly possible that experiences like cyberbullying，comparing yourself to idealized images，and constantly monitoring your profile，it's safe to say that at least we shouldn't write off social media altogether. （5）　 　Anyway，you cannot use it as a crutch for coping with other stressors and mental health problems.
A.The same is true of social media.
B.Social media can be a double﹣edged sword.
C.People get more opinionated about the potential problems of social media.
D.They found that those who used social media more had higher depression scores.
E.They reviewed all existing research and found that there were both benefits and drawbacks.
F.The key to benefiting from social media may lie in using them in moderation and staying socially connected.
