Unit1 using the language 写作课后巩固练习 一、.阅读理解 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. 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. 1. What does the underlined word"shed"mean in paragraph 1? A. Bring in. B. Shake off. C. Make up. D. Take pride in 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.it 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. 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 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,researchers from the conducted by 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. 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. 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. 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. 二、应用文写作 假定你是某国际学校学生李华。你校新开设了户外运动、科技、舞台剧社团，英国交换生杰夫（Jeff)不知如何选择，写信向你求助，请你给他回信，内容包括： 1.推荐某一社团； 2.推荐理由； 3.表达祝愿。 注意：1.词数80左右; 2.请按如下格式作答。 参考词汇：户外运动社团 the outdoor sports club；科技社团 the science club；舞台剧社团the stage drama club Dear Jeff, Yours, Li Hua 三、读后续写 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 Alex rode his bike on his way home,and Johnson's Pond came into view. Sometimes his dad took him canoeing(划独木舟)there, and Alex loved it. The pond was always so alive with activity, and sometimes Alex discovered turtles（乌龟）sunbathing on sunny rocks. Alex was curious about the turtles he saw. When it was too rainy to go canoeing, he and his dad would go to the library to check out books on turtles. Now it looked like tomorrow might be another sunny day. He decided he would ask Dad if they could go canoeing and look for turtles again. Just then Alex saw something in the road up ahead. It looked like a big gray rock.But it was a funny place for a rock to be. He jumped off to have a look. It turned out that it was actually a large turtle making its way across the road. Alex knew right away it was a snapping turtle. Out of the corner of his eye, he saw a car approaching. The turtle was still only halfway across the road. Alex knew he couldn't pick it up because snapping turtles have a powerful bite and they could even bite off someone's finger! What could he do? Thinking fast, he started waving both hands wildly."Stop! Stop!" he cried. The car slowed to a stop. “Are you alright, Alex?" It was his neighbor,Mrs. Ramos. "I'm fine, Mrs. Ramos," said Alex."I'm just trying to save a turtle. It's probably going to lay egg.” “Oh, yeah. It's spring," said Mrs.Ramos."So,I guess a lot of turtles need to lay their eggs in the grass across the road."Then she waved goodbye and drove off. Alex thought about what Mrs. Ramos had said. "There would probably be more turtles trying to cross the road at this spot!"he realized. But he couldn't stand there all day trying to stop cars. He looked around and a road sign caught his eye. And then his face brightened. 注意：续写词数应为150个左右。 He jumped on his bike and raced home to find Dad. The next morning,Dad and Alex drove to the pond with the wooden sign in the car. 参考答案 一、.1-4 BDAD 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.

Hearing Alex's full explanation, Dad then smiled knowingly. Then the dad and son devoted themselves to cutting a wood board into the right "T"shape. After that, Alex wrote down a line with red paint on both sides of the sign, reading,“Slow!Turtles Crossing!"Work all done, they put the wooden sign into their car and went for dinner. The next morning, Dad and Alex drove to the pond with the wooden sign in the car. Upon arriving, they sprang into action. Alex pulled the sign to the side of the road and held it tightly while Dad hammered it into the ground, Sweat dripping into their eyes, they worked with passion until the sign got fixed firmly in the ground. Alex stepped back and surveyed their work.“Slow! Turtles Crossing!" he read out loud and grinned."Ready to go canoeing?""Yes!"Alex blurted out, rushing to the pond with pride. 学科网（北京）股份有限公司 $
