chanong One of the main advantages of the sharing economy is its potential to increase efficiency. By enabling individuals to share resources, it reduces the need for excessive production and consumption. This not only benefits the providers, who can earn additional income, but also the consumers, who can access services at a lower cost. For example, ride – sharing often offers more affordable transportation options compared to traditional taxi services. Moreover, the sharing economy can contribute to environmental sustainability. Fewer cars on the road due to ride – sharing means less fuel consumption and lower emissions.
However, the sharing economy also faces several challenges. One major issue is regulatory uncertainty. Since these new business models often operate in a gray area between traditional industries, it\’s difficult for regulators to determine appropriate rules. For example, ride – sharing drivers may not be subject to the same licensing and safety regulations as taxi drivers, which raises concerns about passenger safety. Additionally, there are problems related to trust. In a sharing economy, transactions often occur between strangers. Establishing trust between the parties involved is crucial but can be challenging. For example, hosts on Airbnb may worry about the behavior of guests, and guests may be concerned about the accuracy of property descriptions.
Despite these challenges, the future of the sharing economy looks promising. With the continuous development of technology, new sharing – based services are likely to emerge. For example, there are already platforms for sharing tools, equipment, and even skills. As society becomes more accepting of the concept of sharing, the sharing economy has the potential to reshape various industries and our daily lives.

答案及解析
1. 答案：B
解析：文章既阐述了共享经济的优势，如提高效率、降低成本、有利于环境可持续性等，又提到了其面临的挑战，如监管不确定性和信任问题，所以主旨是共享经济是一种有优势也有挑战的新经济模式，B选项正确。A选项文章并没有比较优势和劣势的多少；C选项文中未提及共享经济会取代传统产业；D选项共享经济不仅给消费者带来好处，也给提供者带来收入，所以A、C、D均错误。
2. 答案：B
解析：根据文章“Fewer cars on the road due to ride – sharing means less fuel consumption and lower emissions.”可知，共享经济通过减少道路上汽车的数量来促进环境可持续性，B选项正确。A选项鼓励人们更多使用公共交通文章未提及；C选项促进清洁能源使用文中未体现；D选项减少商品生产不是共享经济促进环境可持续性的方式，所以A、C、D错误。
3. 答案：C
解析：文中明确提到“One major issue is regulatory uncertainty.”，说明共享经济面临的挑战之一是监管不确定性，C选项正确。A选项高运营成本、B选项缺乏技术支持、D选项低市场需求在文中均未提及，所以A、B、D错误。
4. 答案：D
解析：从文章“Despite these challenges, the future of the sharing economy looks promising. With the continuous development of technology, new sharing – based services are likely to emerge.”可以推断出共享经济未来会继续发展并拓展到新领域，D选项正确。A选项虽然共享经济面临监管挑战，但不能推断出未来会面临更多；B选项文中说未来有前景，而不是因信任问题发展缓慢；C选项文中未提及创造更多就业机会，所以A、B、C错误。

News report 3
A Philippine fisherman was feeling down on his luck when[Q5] a housefire forced him to[Q6] clear out his possessions and change locations.Then, a good luck charm that he had kept under his bed changed his life.
The unidentified man had fished out a giant pearl from the ocean when his anchor got stuck on the rock while sailing off a coastal island in the Philippines ten years ago.
When [Q6] he was forced to sell it, the shocked tourist agent at Puerto Princesca told him[Q7] that the 77-pound giant pearl that he had kept hidden in his rundown wooden house was the biggest pearl in the world, which was valued at £76 million.
The pearl of Allah, which is currently on display in a New York museum, only weighs 14 pounds. That is five times smaller than the pearl that the fisherman just handed in.
The monstrous pearl, measured at 1 foot wide and 2.2 feet long, is going to be verified by local experts and international authorities before hopefully going on display to attract more tourists in the little town.
Q5: What happened to the Philippine fisherman one day?
Q6: What was the fisherman forced to do?
Q7: What did the fisherman learn from the tourist agent?

Woman: Wow, congratulations, Simon! The place looks absolutely amazing!
Man: Really? You think so?
W: Of course. I love it. It looks like you had a professional interior designer. But you didn’t, did you?
M: No. I did it all by myself with a little help from my brother, Greg. He’s actually in the construction business, which was really helpful.
W: Honestly, I’m impressed! I know I can probably repaint the walls in my house over a weekend or something, but not a full renovation. Where did you get your ideas? I wouldn’t know where to start.[12]
M: Well, for a while now, I’ve been regularly buying home design magazines. Every now and then, I’d saved the pictures I liked. Believe it or not, I have a full notebook of magazine pages. [13] Since by overall style was quite minimal, I thought and hoped a whole renovation wouldn’t be too difficult. And sure enough, with Greg’s help, it was very achievable.
W: Wasn’t it expensive? I have imagined a project like this could be.
M: Actually, it was surprisingly affordable. I managed to sell a lot of my old furniture and put that extra money towards the new material. [14] Greg was also able to get some discount materials from a recent project he was working on as well.
W: Great! If you don’t mind, I’d like to pick your brain a bit more. Johansson and I are thinking of renovating our sitting room, not the whole house, not yet anyway. And we’d love to get some inspiration from your experience. [15] Are you free to come over for a coffee early next week?

Passage 1
Removing foreign objects from ears and noses costs England almost £3m a year, a study suggests.[Q16]Children were responsible for the vast majority of cases – 95% of objects removed from noses and 85% from ears. Every year, an average of 1,218 nose and 2,479 ear removals took place between 2010 and 2016.According to England\’s Hospital Episode Statistics, children aged one to four were the most likely to need help from doctors for a foreign object in their nose. Five to nine year olds come to the hospital with something in their ear the most. Jewelry items accounted for up to 40% of cases in both the ears and noses of children. [Q17]Paper and plastic toys were the items removed next most from noses. Cotton buds and pencils were also found in ears.
According to the study, the occurrence of foreign objects in children is generally attributed to curiosity. Children have an impulse to explore their noses and ears. This results in the accidental entry of foreign objects. [Q18]Any ear, nose and throat surgeon has many weird stories about wonderful objects found in the noses and ears of children and adults. Batteries can pose a particular danger. In all cases, prevention is better than cure. This is why many toys contain warnings about small parts. Recognizing problems early and seeking medical attention is important.
Q16: What does England spend an annual £3m on?
Q17: What do we learn from England\’s Hospital Episode Statistics?
Q18: What is generally believed to account for children putting things in their ears or noses?

Passage Two
Good morning, I’d like to talk to you about my charity ReBicycle. But before that, let me introduce someone. This is Leila Rahimi. She was so scared when she first moved to New Zealand that she struggled to leave the house and would spend days working up the courage to walk to the supermarket for basic supplies. After a few months of being quite down and unhappy, she was invited to join a local bike club.At this time, ReBicycle got involved and gave Leila a second-hand bicycle.[Q19]In weeks, her depression had begun to ease as she cycled. The bicycle totally changed her life, giving her hope and a true feeling of freedom.
To date, ReBicycle has donated more than 200 bikes to those in need, and is now expanding bike-riding lessons as demand soars.[Q20]With a bike, you can travel farther but for almost no cost. The three hours a day that used to spend on walking to and from English language lessons has been reduced to just one hour.Our bike-riding lessons are so successful that we are urgently looking for more volunteers. [Q21]Learning to ride a bike is almost always more difficult as an adult, and this can take days and weeks, rather than hours. So, if any of you have some free time during the weekend, please come join us at ReBicycle and make a difference in someone’s life.
Q19: What did ReBicycle do to help Leila Rahimi?
Q20: What is ReBicycle doing to help those in need?
Q21: What do we learn from the passage about the ReBicycle?

Passage 3
Thanks to the International Space Station we know quite a bit about the effects of low gravity on the human body, but NASA scientists want to learn more. To that end, they have been studying how other species deal with low gravity, specifically focusing on mice（Q22）. The results are both interesting and humorous.
The scientists first send some mice in a specially designed cage to the International Space Station. The cage allowed them to study the behavior of the mice remotely from Earth via video. As you noticed in the video, the mice definitely seem uncomfortableat the beginning of the experiment. They move around clumsily, drifting within the small confines of the cage and do their best to figure out which way is up, but without success. (Q23) However, it’s not long before the mice begin to catch on. They adapt remarkably well to their new environment and even using the lack of gravity to their advantage as they push themselves around the cage.
That’s when things really get wild.The 11th dayof the experiment shows the mice are not just dealing with the gravity change but actually seem to be enjoying it. (Q24) Several of the mice are observed running around the cage walls.
The scientists wanted to see whether the mice would continue doing the same kinds of activities they were observed doing on Earth.The study showed thatthe mice kept much of their routines intact, including cleaning themselves and eating when hungry. (Q25)
Q22 What do Nasa scientists want to learn about?
Q23 What does the passage say about the miceat the beginning ofthe experiment?
Q24 What was observed about the miceon the 11th dayof the experiment?
Q25 What did the scientists find about the mice from the experiment?
