However，after the astonishment wore off(消退)，some teens began to realize that they might be addicted to(上瘾) social media and phones.They wondered if too much screen time and worry about getting “likes” were harmful. The Board of Education decided to ban cellphones by January 2025 to change the behavior of students.This move holds great importance，especially since students were forced to go to class online—many by phone—more than four years ago. School leaders believe that this ban will lessen classroom distractions(分神) that hurt learning and reduce social media dependence. They think that a strict ban can encourage direct communication among students and teachers. William understands the reasoning behind the ban.He knows phones can be distracting，especially when students focus on social media rather than real-life conversations.He’s caught himself repeatedly checking how many people liked a story he posted recently of him and a friend on an outing. For Angelica Zamora-Reyes,17，a senior at Downtown Magnets High School，the ban can’t come soon enough.She has experienced the downsides of phones.Despite using her phone for good，like keeping in touch with family，she also recognizes the problems，such as comparing their clothes，weight and likes on social media. In general，the idea of banning cellphones creates debate，and many students see both good and bad points. 4.What can be learned about William from paragraph 1? A.He is glued to his phone. B.He is a sixth grader now. C.He prefers to write letters. D.He often makes phone calls. √ 细节理解题。根据第一段“Since William Schnider got his first cellphone in sixth grade，it has become a big part of his life.During the day，he keeps it in his right pocket，and at night，it’s within arm’s reach.He doesn’t often make calls；instead，he chats on social media and sends texts.”可知，William沉迷于手机，故选A。 解析 5.What does the underlined word “astonishment” in paragraph 3 mean? A.Creativity. B.Surprise. C.Discussion. D.Interest. √ 词义猜测题。根据第二段内容以及画线词后文“some teens began to realize that they might be addicted to(上瘾) social media and phones”可知，第二段提到William Schnider对洛杉矶公立学校禁止使用手机的规定表示怀疑，而后文提到一些青少年开始意识到他们可能沉迷于社交媒体和手机，这说明这些青少年对禁止使用手机的规定一开始是惊讶的，即画线词意思是“惊讶的”。故选B。 解析 6.What do school leaders hope to achieve by applying the ban? A.Teachers will care more about students. B.Every classroom will get clean and tidy. C.Students will break free from cellphones. D.Parents will speak in support of the rule. √ 细节理解题。根据第五段“School leaders believe that this ban will lessen classroom distractions(分神) that hurt learning and reduce social media dependency.They think that a strict ban can encourage direct communication among students and teachers.”可知，学校领导希望通过实施禁令让学生摆脱手机。故选C。 解析 7.What is Angelica’s opinion about the ban? A.It’ll force her to lose weight. B.She welcomes the decision. C.It’ll benefit service providers. D.She is against the new rule. √ 观点态度题。根据倒数第二段中的“For Angelica Zamora-Reyes,17，a senior at Downtown Magnets High School，the ban can’t come soon enough.”可知，Angelica欢迎这个决定。故选B。 解析 Having a dog is good for your health. 1 You need to organize your day well and adjust(调整) it for your dog’s daily walking needs.Here are some safe dog walking tips. Ⅴ.七选五阅读 A.Never leave your dog alone on walks. B.However，walking your dog can cost you much time. C.These are safe places to do fun outdoor games for your dog. D.So you need to know your dog and find out its energy level. E.The best dog owners are those who often go to different shops. F.Social meetups help make sure that your dog becomes a friendly pet. G.You，as the owner，should pay attention to everything that your dog eats. √ 语篇解读　本文是一篇说明文。文章主要介绍了几条安全遛狗的小贴士。 根据前文“Having a dog is good for your health.”以及后文“You need to organize your day well and adjust(调整) it for your dog’s daily walking needs.”可知，这两句话之间需要一个过渡句，说明养狗虽然对健康有好处，但也需要一定的付出，特别是时间上的付出。因此，B选项“然而，遛狗会花费你很多时间”符合语境，故选B。 解析 A.Never leave your dog alone on walks. B.However，walking your dog can cost you much time. C.These are safe places to do fun outdoor games for your dog. D.So you need to know your dog and find out its energy level. E.The best dog owners are those who often go to different shops. F.Social meetups help make sure that your dog becomes a friendly pet. G.You，as the owner，should pay attention to everything that your dog eats. √ 2 Of course，the situation may happen when you badly need to go，for example，to a shop and then you have to leave the dog on a leash(狗链).But you must not often leave the animal like this because you endanger its life.And the dog can be a danger to people on the street. 设空处位于段首，为本段中心句，根据后文“Of course，the situation may happen when you badly need to go，for example，to a shop and then you have to leave the dog on a leash(狗链).But you must not often leave the animal like this because you endanger its life.And the dog can be a danger to people on the street.”可知，本段主要讲述了遛狗时不要单独把狗留下，否则对狗本身和行人都会造成危害。所以A选项“遛狗时千万不要把狗单独留下”符合语境，引出下文，故选A。 解析 A.Never leave your dog alone on walks. B.However，walking your dog can cost you much time. C.These are safe places to do fun outdoor games for your dog. D.So you need to know your dog and find out its energy level. E.The best dog owners are those who often go to different shops. F.Social meetups help make sure that your dog becomes a friendly pet. G.You，as the owner，should pay attention to everything that your dog eats. √ Pick less visited places.When choosing a place for walking with a dog，you had better pick less visited squares and parks，and other less popular areas where there are only a small number of people. 3 设空处位于段尾，是对前文的总结，根据前文“Pick less visited places...there are only a small number of people.”可知，应该去人少的地方遛狗，空处应对此进行解释说明，说明这些地方是安全的，适合狗狗玩耍。因此，C选项“这些都是安全的地方，可以让你的狗狗做有趣的户外游戏”符合语境，故选C。 解析 A.Never leave your dog alone on walks. B.However，walking your dog can cost you much time. C.These are safe places to do fun outdoor games for your dog. D.So you need to know your dog and find out its energy level. E.The best dog owners are those who often go to different shops. F.Social meetups help make sure that your dog becomes a friendly pet. G.You，as the owner，should pay attention to everything that your dog eats. √ Take the best number of walks in a day for your dog.Though even just one walk every day may be enough for smaller dogs，high-energy dogs will need more than that. 4 The question of how much time to walk is also important. The best choice is to prepare at least 40 minutes for a walk with your dog. 根据前文“Take the best number of walks in a day for your dog...will need more than that.”以及后文“The question of how much time to walk is also important.The best choice is to prepare at least 40 minutes for a walk with your dog.”可知，不同体型或不同能量水平的狗的运动量也是不同的，这说明需要了解狗狗的能量水平，来合理安排遛狗次数。因此，D选项“所以你需要了解你的狗狗，了解它的能量水平”符合语境，故选D。 解析 A.Never leave your dog alone on walks. B.However，walking your dog can cost you much time. C.These are safe places to do fun outdoor games for your dog. D.So you need to know your dog and find out its energy level. E.The best dog owners are those who often go to different shops. F.Social meetups help make sure that your dog becomes a friendly pet. G.You，as the owner，should pay attention to everything that your dog eats. √ Take your dog to meetups.Dogs enjoy meetups with other dogs.Plan dog meetups and group-walks for your dog to play with other dogs.Walking in a group means you get to share experiences with other dog owners as well. 5 So take your dog out to meet up with other dogs.It is good for their health. 根据前文“Take your dog to meetups...share experiences with other dog owners as well.”以及后文“So take your dog out to meet up with other dogs.It is good for their health.”可知，带狗参加狗狗聚会有很多好处，此空应承接上文，继续说明狗狗聚会的好处，所以F选项“社交聚会有助于确保你的狗成为一个友好的宠物”符合语境，故选F。 解析 本课结束 $
