阅读下面材料，根据其内容和所给段落开头语续写一个80词左右的段落，使之构成一篇完整的短文。
John and Bobby joined a wholesale company together just after graduation from college the same year． Both they worked very hard． After several years, however, the boss promoted Bobby to the position of manager but John remained an ordinary employee． John could not take it anymore, submitted his resignation to the boss and complained the boss did not value hard-working staff．
The boss knew that John worked very hard for the years． He thought a moment and said, “I hope you will do one more thing for our company before you leave． Perhaps you will change your decision and take back your resignation．”
John agreed． The boss asked him to go and find out anyone selling watermelons in the market． John went and returned soon． He said he had found out a man selling watermelons． The boss asked how much per kg John shook his head and went back to the market to ask and returned to inform the boss of the price —$1.2 per kg．
The boss told John to wait a second, and he asked Bobby to go and find anyone selling watermelons in the market． Bobby went, returned and said, “Boss, only one person sells watermelons． $1.2 per kg, $10 for 10 kg, he has a supply of 340 melons． On the table are 58 watermelons, and every watermelon weighs about 2 kg, bought from the South two days ago． They are fresh and good quality．” After the careful report, Bobby waited for the reply of the boss． At that moment, the boss stared at John without any words．
John realised the difference from Bobby．____________________

John realised the difference from Bobby． Shocked by Bobby's perfect performance, John was lost in thought, unable to utter a single word． It was quite a while before John made his final decision． Instead of leaving the company like a drowned mouse, he decided to stay and prove his ability． “I am bound to make it！” John said to the boss with a determined look, taking back the resignation． After that, not only did John work harder than before, but he also learned from Bobby with an open mind． Thus, John made steady progress in his work．
Ⅰ．阅读理解
A
With no special equipment, no fences and no watering, two abandoned agricultural fields in the UK have been rewilded, in large part due to the efforts of jays(松鸦), which actually “engineered” these new woodlands． Researchers now hope that rewilding projects can take a more natural and hands-off approach and that jays can shed some of their bad reputations．
课时分层作业(三)
The two fields, which researchers have called the New Wilderness and the Old Wilderness, had been abandoned in 1996 and 1961 respectively． The former was a bare field, while the latter was grassland—both lay next to ancient woodlands． Researchers had suspected that the fields would gradually return to wilderness, but it was impressive to see just how quickly this happened, and how much of it was owed to birds．
Using aerial data, the researchers monitored the two sites． After just 24 years, the New Wilderness had grown into a young, healthy wood with 132 live trees per hectare, over half of which (57%) were oaks． Meanwhile, the Old Wilderness resembled a mature woodland after 39 years, with 390 trees per hectare．
“This native woodland restoration was approaching the structure (but not the species composition) of long-established woodlands within six decades，” the researchers explained in the study．
How did this happen Animals—Eurasian jays, thrushes, wood mice, and squirrels played an important role in helping the forests take shape． This handful of species provided much of the natural regeneration needed for the forest to develop． Jays, in particular, seem to have done a lot of heavy lifting． Jays are scatter-hoarders, meaning they like to store food for the winter, which they then subsequently retrieve． Or not． And when they do forget something, a seedling has a chance to grow． These flying ecosystem engineers could be a big help for reforestation．
【语篇解读】 本文是一篇说明文。文章通过研究、检测英国的两块废弃农田被重新野生化的过程，得出结论，重新造林速度比预期要快，并且该过程有了风力和一些为数不多的物种的帮助后，能够加速大自然的更新。
1．What does the underlined word “shed” mean in paragraph 1
A．bring in B．shake off
C．make up D．take pride in
√
B [词义猜测题。根据文章第一段的“With no special equipment, no fences and no watering, two abandoned agricultural fields in the UK have been rewilded, in large part due to the efforts of jays(在没有特殊设备、没有围栏、没有浇水的情况下，英国两块废弃的农田已经重新野生化，这在很大程度上要归功于松鸦的努力)”以及下文“some of their bad reputations(它们的一些坏名声)”可知，松鸦本来是有着坏名声的鸟类，但却帮助两块废弃农田重新野生化，所以是摆脱了坏名声，由此可推知画线词是“摆脱”的意思。故选B项。]
2．What does the author want to show by providing some data in paragraph 3
A．To help the researchers monitor the two sites．
B．To show the difference between the two sites．
C．To inform us how big the two sites are．
D．To show the rapid change of the two sites．
√
D [推理判断题。根据文章第三段的“After just 24 years, the New Wilderness had grown into a young, healthy wood with 132 live trees per hectare, over half of which (57%) were oaks． Meanwhile, the Old Wilderness resembled a mature woodland after 39 years, with 390 trees per hectare．(仅仅24年之后，新荒野就长成了一片年轻、健康的森林，每公顷有132棵活树，其中一半以上(57%)是橡树。与此同时，39年后，旧荒野就像一个成熟的林地，每公顷有390棵树。)”可知，作者进行了数据对比，表示仅24年，新荒野就变成了树林，39年后旧荒野就成了林地，由此可知，作者展示这些数据是为了显示这两个地点的迅速变化。故选D项。]
3．What is the text mainly about
A．Jays aid reforestation．
B．Jays aid protection of wildlife．
C．Researchers make home for species．
D．Researchers make efforts for woodlands．
√
A [主旨大意题。分析全文内容，再根据文章最后一段“Animals—Eurasian jays, thrushes, wood mice, and squirrels played an important role in helping the forests take shape． This handful of species provided much of the natural regeneration needed for the forest to develop． Jays, in particular, seem to have done a lot of heavy lifting．(欧亚松鸦、画眉、木鼠和松鼠等动物在帮助森林形成方面发挥了重要作用。这些为数不多的物种为森林的发展提供了大量的自然再生。尤其是松鸦，似乎做了很多繁重的搬运工作。)”可知，文章的主要内容讲的是松鸦帮助重新造林。故选A项。]
4．In which section of a website can we probably find the text
A．Mind & Brain
B．Agriculture & Technology
C．Business & Industry
D．Biology & Ecology
D [文章出处题。分析全文内容可知，文章主要谈到了生态中重新造林问题以及松鸦等动物在造林中发挥的重要作用，所以这篇文章很可能来自网站的生物与生态学部分。故选D项。]

B
In today's youth culture, it seems as if teens are permanently glued to their cellphones, constantly receiving beeping, buzzing and blinking social media notifications (通知)． We often hear of the harm of social media to teens and young people, but our latest research on young girls and boys has revealed that social media is not always negative．
In some cases, we found that social media can positively influence their health and well-being, by helping them learn about healthy eating or new workouts to try． Besides, social media provides space for young people to talk to each other about issues of health．
For our study, conducted by researchers from the University of Birmingham and Orebro University, we invited over 1，300 young girls and boys, aged 13—18, from ten UK schools． We were interested in better understanding how young people use social media, and how they feel it impacts their health and well-being． To do this, we selected 84 participants from the main sample and had them take part in small group interviews．
The results showed that social media often had a positive influence on young people's motivation for being physically active and on their ability to make conscious diet choices． Social media also allowed them to access the information they found inspirational, and learn about different apps they could use to be physically active or monitor their progress． They reported that likes, comments, and views on their social media posts also helped them stay motivated to exercise．
Encouragingly, the young people we spoke to were also highly discerning users of social media． They thought carefully about the content they were engaging with online． For instance, the teenagers reported that they would often ignore content that had the potential to lead to harm, such as images or videos that presented unrealistic workouts or expectations for their bodies．
While the risks should certainly not be overlooked, our findings show that social media can have a positive effect on young people's health and well-being． A benefit of social media is that it provides real-time, low-cost information, and support from their peers． Making young people use social media safely, critically and responsibly may thus help them continue to lead a healthy life．
【语篇解读】 本文是一篇说明文。文章主要介绍了一项研究发现。社交媒体对年轻人有着负面影响，这仿佛是大家的共识。但最新研究却显示，社交媒体对年轻人的作用可能有两面性。
5．What is the main finding of the latest research mentioned in the text
A．Young people make better use of social media．
B．Teenagers use social media more than expected．
C．Social media proves beneficial to young people．
D．New evidence adds to the harm of social media．
√
C [推理判断题。根据第二段“In some cases, we found that social media can positively influence their health and well-being, by helping them learn about healthy eating or new workouts to try． Besides, social media provides space for young people to talk to each other about issues of health．(在某些情况下，我们发现社交媒体可以通过帮助他们了解健康饮食或尝试新的锻炼方式，对他们的健康和幸福产生积极的影响。此外，社交媒体为年轻人提供了相互谈论健康问题的空间。)”可推断，社交媒体对年轻人有好处。故选C。]
6．How did the researchers carry out their study
A．They made thorough analyses at two universities．
B．They collected data from the database of ten UK schools．
C．They referred to the findings of several previous studies．
D．They conducted group interviews with young girls and boys．
√
D [细节理解题。根据第三段的“we invited over 1，300 young girls and boys, aged 13—18, from ten UK schools(我们邀请了来自10所英国学校的1 300多名13—18岁的年轻女孩和男孩)”及下文“To do this, we selected 84 participants from the main sample and had them take part in small group interviews．(为此，我们从主要样本中选择了84名参与者，并让他们参加小组访谈。)”可知，研究人员邀请了男孩女孩，然后以小组采访的形式展开研究。故选D。]
7．What kind of young people do the underlined words “discerning users” in paragraph 5 probably refer to
A．People having great freedom．
B．People enjoying special privileges．
C．People showing good judgment．
D．People having an influence on others．
√
C [词义猜测题。根据画线词后文“They thought carefully about the content they were engaging with online． For instance, the teenagers reported that they would often ignore content that had the potential to lead to harm, such as images or videos that presented unrealistic workouts or expectations for their bodies．(他们会仔细考虑他们在网上接触的内容。例如，青少年报告说，他们经常会忽视那些有可能导致伤害的内容，比如展示不切实际的锻炼或对自己身体的期望的图像或视频。)”可知，接受采访的这些年轻人在社交媒体上极具洞察力。所以discerning users指的是对社交媒体有良好的判断力的年轻人。故选C。]
8．What is the author's advice for young social media users
A．Making full use of their online time．
B．Using social media in a smart way．
C．Taking full responsibility for their health．
D．Keeping informed of low-cost information．
√
B [推理判断题。根据最后一段的“Making young people use social media safely, critically and responsibly may thus help them continue to lead a healthy life．(因此，让年轻人安全地、批判性和负责任地使用社交媒体可能有助于他们继续过上健康的生活。)”可推断，作者建议年轻人明智地使用社交媒体。故选B。]

In today's youth culture, it seems as if teens are permanently glued to their cellphones, constantly receiving beeping, buzzing and blinking social media notifications (通知)． We often hear of the harm of social media to teens and young people, but our latest research on young girls and boys has revealed that social media is not always negative．
In some cases, we found that social media can positively influence their health and well-being, by helping them learn about healthy eating or new workouts to try． Besides, social media provides space for young people to talk to each other about issues of health．
For our study, conducted by researchers from the University of Birmingham and Orebro University, we invited over 1，300 young girls and boys, aged 13—18, from ten UK schools． We were interested in better understanding how young people use social media, and how they feel it impacts their health and well-being． To do this, we selected 84 participants from the main sample and had them take part in small group interviews．
The results showed that social media often had a positive influence on young people's motivation for being physically active and on their ability to make conscious diet choices． Social media also allowed them to access the information they found inspirational, and learn about different apps they could use to be physically active or monitor their progress． They reported that likes, comments, and views on their social media posts also helped them stay motivated to exercise．
Encouragingly, the young people we spoke to were also highly discerning_users of social media． They thought carefully about the content they were engaging with online． For instance, the teenagers reported that they would often ignore content that had the potential to lead to harm, such as images or videos that presented unrealistic workouts or expectations for their bodies．
While the risks should certainly not be overlooked, our findings show that social media can have a positive effect on young people's health and well-being． A benefit of social media is that it provides real-time, low-cost information, and support from their peers． Making young people use social media safely, critically and responsibly may thus help them continue to lead a healthy life．
5．What is the main finding of the latest research mentioned in the text
A．Young people make better use of social media．
B．Teenagers use social media more than expected．
C．Social media proves beneficial to young people．
D．New evidence adds to the harm of social media．

A．People having great freedom．
B．People enjoying special privileges．
C．People showing good judgment．
D．People having an influence on others．

Dear Jeff，
I'm Li Hua． As for your hard choice you mentioned in your last letter, I'd like to give you my recommendation—the stage drama club． My reasons are as follows．
In the club, you can enjoy a variety of activities including watching the original drama and acting out some classical plots with your partners． Participating in it, you can be exposed to a pure Chinese environment and have a deep insight into the Chinese literature． What's more, it is also a good way to foster the ability of self-expression and improve self-confidence． Your active participation is also helpful to your communication skills and managing interpersonal relationship．
I'm firmly confirmed that the stage drama club is the best choice for you． Looking forward to your participation．
Yours，
Li Hua
Ⅰ．【语篇解读】 本文是一篇说明文。文章通过研究、检测英国的两块废弃农田被重新野生化的过程，得出结论，重新造林速度比预期要快，并且该过程有了风力和一些为数不多的物种的帮助后，能够加速大自然的更新。
1．B [词义猜测题。根据文章第一段的“With no special equipment, no fences and no watering, two abandoned agricultural fields in the UK have been rewilded, in large part due to the efforts of jays(在没有特殊设备、没有围栏、没有浇水的情况下，英国两块废弃的农田已经重新野生化，这在很大程度上要归功于松鸦的努力)”以及下文“some of their bad reputations(它们的一些坏名声)”可知，松鸦本来是有着坏名声的鸟类，但却帮助两块废弃农田重新野生化，所以是摆脱了坏名声，由此可推知画线词是“摆脱”的意思。故选B项。]
2．D [推理判断题。根据文章第三段的“After just 24 years, the New Wilderness had grown into a young, healthy wood with 132 live trees per hectare, over half of which (57%) were oaks． Meanwhile, the Old Wilderness resembled a mature woodland after 39 years, with 390 trees per hectare．(仅仅24年之后，新荒野就长成了一片年轻、健康的森林，每公顷有132棵活树，其中一半以上(57%)是橡树。与此同时，39年后，旧荒野就像一个成熟的林地，每公顷有390棵树。)”可知，作者进行了数据对比，表示仅24年，新荒野就变成了树林，39年后旧荒野就成了林地，由此可知，作者展示这些数据是为了显示这两个地点的迅速变化。故选D项。]
3．A [主旨大意题。分析全文内容，再根据文章最后一段“Animals—Eurasian jays, thrushes, wood mice, and squirrels played an important role in helping the forests take shape． This handful of species provided much of the natural regeneration needed for the forest to develop． Jays, in particular, seem to have done a lot of heavy lifting．(欧亚松鸦、画眉、木鼠和松鼠等动物在帮助森林形成方面发挥了重要作用。这些为数不多的物种为森林的发展提供了大量的自然再生。尤其是松鸦，似乎做了很多繁重的搬运工作。)”可知，文章的主要内容讲的是松鸦帮助重新造林。故选A项。]
4．D [文章出处题。分析全文内容可知，文章主要谈到了生态中重新造林问题以及松鸦等动物在造林中发挥的重要作用，所以这篇文章很可能来自网站的生物与生态学部分。故选D项。]
【语篇解读】 本文是一篇说明文。文章主要介绍了一项研究发现。社交媒体对年轻人有着负面影响，这仿佛是大家的共识。但最新研究却显示，社交媒体对年轻人的作用可能有两面性。
5．C [推理判断题。根据第二段“In some cases, we found that social media can positively influence their health and well-being, by helping them learn about healthy eating or new workouts to try． Besides, social media provides space for young people to talk to each other about issues of health．(在某些情况下，我们发现社交媒体可以通过帮助他们了解健康饮食或尝试新的锻炼方式，对他们的健康和幸福产生积极的影响。此外，社交媒体为年轻人提供了相互谈论健康问题的空间。)”可推断，社交媒体对年轻人有好处。故选C。]
6．D [细节理解题。根据第三段的“we invited over 1，300 young girls and boys, aged 13—18, from ten UK schools(我们邀请了来自10所英国学校的1 300多名13—18岁的年轻女孩和男孩)”及下文“To do this, we selected 84 participants from the main sample and had them take part in small group interviews．(为此，我们从主要样本中选择了84名参与者，并让他们参加小组访谈。)”可知，研究人员邀请了男孩女孩，然后以小组采访的形式展开研究。故选D。]
7．C [词义猜测题。根据画线词后文“They thought carefully about the content they were engaging with online． For instance, the teenagers reported that they would often ignore content that had the potential to lead to harm, such as images or videos that presented unrealistic workouts or expectations for their bodies．(他们会仔细考虑他们在网上接触的内容。例如，青少年报告说，他们经常会忽视那些有可能导致伤害的内容，比如展示不切实际的锻炼或对自己身体的期望的图像或视频。)”可知，接受采访的这些年轻人在社交媒体上极具洞察力。所以discerning users指的是对社交媒体有良好的判断力的年轻人。故选C。]
8．B [推理判断题。根据最后一段的“Making young people use social media safely, critically and responsibly may thus help them continue to lead a healthy life．(因此，让年轻人安全地、批判性和负责任地使用社交媒体可能有助于他们继续过上健康的生活。)”可推断，作者建议年轻人明智地使用社交媒体。故选B。]
