WELCOME UNIT WELCOME UNIT 单元限时小练(50分钟) Ⅰ　阅读 A My roommate Lily was well organised, while I was not. Each of her things had its place, but mine were always hidden somewhere. She even labeled (贴标签于) everything. I always looked for everything. Over time, Lily got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other. War broke out one evening. Lily came into the room. Soon, I heard her screaming. “Take your shoes away! Why under my bed！” Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder. 单元限时小练 2 The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Lily answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled (爬) under her covers, sobbing. Obviously, that was something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart. Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so lost in my work that I didn't even notice Lily had sat up. She was watching, her tears dried and her expression a kind of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me and said, “Thanks.” 单元限时小练 3 Lily and I stayed roommates for the rest of the college years. We didn't always agree, but we learned. 篇章导读：本文是一篇记叙文。文章讲述了作者与室友因生活习惯的差异而产生矛盾，最终学会了如何与室友相处的经历。 单元限时小练 4 1．How is Paragraph 1 mainly developed? A．By analyzing causes. B．By following time order. C．By showing differences. D．By describing a process. 解析：推理判断题。作者在第一段详细叙述了Lily (莉莉)是一个很有条理的人，她的东西总是整齐有序，有些东西甚至贴上了标签，而作者不爱整理，东西乱丢乱放，由此可推知，作者是通过对比两人生活习惯的差异展开该段内容的。故选C。 单元限时小练 5 2．What made Lily so angry one evening? A．She heard the author shouting loud. B．She saw the author's shoes under her bed. C．She got the news that her grandma was ill. D．She couldn't find her books anymore. 解析：细节理解题。根据第二段中的“Take your shoes away! Why under my bed！”可知，让Lily发怒的是她看见作者的鞋子在她的床下面。故选B。 单元限时小练 6 3．Why did the author clean up the room? A．Because she wanted to show her care for Lily. B．Because she hated herself for being so messy. C．Because Lily required her to do so. D．Because she was scared by Lily's anger. 解析：推理判断题。根据第三段内容尤其是该段最后一句“All of a sudden, a warm feeling of sympathy rose up in my heart.”可知，因为Lily的奶奶生病了，她非常难过，所以作者突然对Lily产生了同情，然后开始主动打扫房间。由此可推知，作者这样做是为了表示自己对Lily的关心。故选A。 单元限时小练 7 4．What might be the best title for the passage? A．Hard Work Pays Off B．Learning to Be Roommates C．My Friend Lily D．How to Be Organised? 解析：标题判断题。通读全文可知，本文主要讲述了作者与室友Lily因生活习惯大不相同，两人发生了一场冲突，也因此作者学会了关心室友，学会了如何与室友相处。B项(学会与室友相处)最适合作为文章标题。故选B。 单元限时小练 8 B School field trips have been part of the educational experience for children across the US for decades. While many schools believe there's value in letting students develop socially with out­of­classroom experiences, measuring the influence and the value of field trips is difficult. And showing the value of out­of­class time can be challenging for teachers tasked with providing a good education. 单元限时小练 9 As such, many art venues, science museums and zoos have reported drops in field trip attendance. Teachers and students have also reported falling numbers of school supported trips, particularly for minority students in academically low­performing schools. But thanks to new research from Brigham Young University and the Heritage Foundation, the value of field trips is finally being understood. The study used an experimental design and randomly arranged fourth­ and fifth­grade students from fifteen elementary schools in Atlanta to join in three field trips during a school year. The field trips included a trip to a gallery, a live theater performance and a symphony concert. 单元限时小练 10 Students who attended three different field trips in the fourth or fifth grade scored higher on end­of­grade exams, received higher course grades, were absent less often and had fewer behavioral problems. Besides academic (学业的) improvements, students who took part in field trips were more likely to express a desire to have career­related fields in the future. In parents' opinion, they are very interested in the academic quality of their children's schools, but they're also interested in the social skills and social engagement habits they develop. Field trips are easy ways to help improve both. 单元限时小练 11 “We expected that field trips wouldn't harm test scores. However, we never predicted the all­around improvements for students who joined in these field trips，” said Erickson, a researcher in the study. “One potential reason for this is that field trips widen students' world concepts and introduce them to new ideas. Similarly, students might be more engaged in school thanks to field trips. Students find school more exciting and want to try harder in class.” 篇章导读：本文是一篇说明文。一项研究表明，参加实地考察的学生考试成绩更好，在课堂上表现更好。 单元限时小练 12 5．Why do the number of school field trips drop? A．Teachers give students too many tasks. B．Schools have great problems with money. C．The value of field trips is hard to be measured. D．Students have difficulty in academic learning. 解析：细节理解题。根据第一段中的“measuring the influence and the value of field trips is difficult”可知，实地考察的价值很难被衡量，所以学校实地考察的次数下降了。故选C。 单元限时小练 13 6．What is the theme of the field trips in the study? A．Art. B．Nature. C．Sports. D．Technology. 解析：细节理解题。根据第三段中的“The field trips included ... a symphony concert.”可知，在这项研究中实地考察的主题是艺术。故选A。 单元限时小练 14 7．What can we infer about students who joined in the study? A．They have more interests. B．They become more adventurous. C．They have more self­control. D．They become more curious. 解析：推理判断题。根据第四段中的“Students who attended ... fewer behavioral problems.(在四年级或五年级参加过三次不同实地考察的学生在期末考试中得分更高、课程成绩更优、缺课次数更少、行为问题也更少。)”可推知，他们的自控能力更好。故选C。 单元限时小练 15 8．What is Erickson's attitude towards the result of the study? A．Doubtful. B．Negative. C．Disappointed. D．Surprised. 解析：推理判断题。根据最后一段中的“We expected that ... in these field trips(我们原以为实地考察不会影响考试成绩。然而，我们从未预料到参加这些实地考察的学生会获得全面提升)”可知，研究结果出乎Erickson(埃里克森)的预料，他应是对此感到惊讶。故选D。 单元限时小练 16 Ⅱ　七选五 How to Motivate (激励) a Lazy Teenager Here's how to give the teenagers the motivation they need without nagging (唠叨) them. __1__ A teenager needs between 8－10 hours of sleep every night but most only get about 6.5－7.5 hours of sleep per night. So when a teenager is forced out of bed at 7 am or 8 am to go to school, their natural sleep cycle is thrown off and they will likely appear lazy, unmotivated, all symptoms (症状) of lack of sleep. __2__. 经验贴5　七选五通常一段一题，少于5段或某段较长，可一段两题。 单元限时小练 17 Limit screen time It is recommended that teenagers spend no more than two hours a day sitting in front of a small screen and get 60 minutes' exercise a day. __3__. Teach responsibility It's important for teenagers to help with tasks and learn responsibility. __4__. Be firm and clear about the results for not finishing the housework—this can range from no screen time, to less pocket money or not being allowed to go out with their friends.

When teenagers know adults are emotionally available to support them, a welcome change in their behaviour may be seen. 单元限时小练 18 A.Set a sleep schedule B.Understand their thoughts C.Make sure that teenagers can do homework alone D.Set a plan with teenagers for the daily housework they would prefer to do E.However, they need to know that adults love them, care for them and respect them F.Make sure the teenager goes to bed on time and gets eight hours of sleep a night G.Make screen time a reward by ensuring teenagers finish their homework or tasks first 篇章导读：本文是一篇说明文。文章介绍了如何激励青少年充满动力。 单元限时小练 19 1．答案：A 解析：设空处为本段小标题，根据后文可知，本段主要强调孩子懒惰的原因在于睡眠的时间周期被打乱，应解决青少年的睡眠问题。A项(设定睡眠时间表)概括本段内容，可作为本段小标题。故选A。 2．答案：F 解析：根据前文可知，青少年显得懒惰、没有动力，是睡眠不足导致的。F项(确保青少年按时上床睡觉，每晚睡足8小时)针对前文的问题提出了解决方案。故选F。 单元限时小练 20 3．答案：G 解析：根据本段小标题“Limit screen time(限制看屏幕时间)”可知，G项(确保青少年先完成作业或任务，把看屏幕的时间作为奖励)与小标题呼应。故选G。 4．答案：D 解析：根据设空处后的“Be firm and clear about the results for not finishing the housework (坚决明确不做完家务的后果)”可知，D项(为青少年制订一个他们喜欢做的日常家务的计划)引出后文。故选D。 单元限时小练 21 5．答案：E 解析：根据本段小标题“Show them the love(向他们表达爱)”以及设空前的“Teenagers might not act like they need it or want it. (青少年可能表现出他们需要或是想要它。)”可知，E项(然而，他们需要知道成年人爱他们，关心他们，尊重他们)与前文构成转折关系，且符合本段主旨。故选E。 单元限时小练 22 Ⅲ　完形填空 When Marco was a boy, he tried everything to get his father's love and attention.
