It seems like a crazy idea from a horror But it could happen in the near future.Canadian biophysicist Andrew Pelling used an apple to grow a human ear. He think fruitand vegetables can be used to cheaply repair human body parts in the future.Scientists have been trying to grow organs( 器官 ) in labs to replace our old ones. But it is a hard job.For example, liver cells (肝细胞) can grow in a lab, but he cells still need things like blood vessels (血管) to actually things have to grow inside a scaffold( In the past, scientists have used man-made materials, animals parts and even dead peopleas scaffolds. But that has proved to be difficult and expensive.Pelling and his team, however, f ound the apple to be a cheap and easy-to-use scaffold. They first cut an apple into the shape of an ear. Then they used a special way to take outthe apple ’s cell and make it a scaffold. The team then added human cells to the apple, andwatched it grow.“You can implant these scaffolds into the body, and the body will send in cells and ablood supply and actually keep these thi ngs alive,” Pelling said during a Ted Talk speech.The team put the apple scaffold inside a living mouse and the mouse’s cells slowly took over the pieces of apple.Now Pelling is thinking of other fruit, plants or vegetables to use.He says that the shape of flower petals could be perfect for repairing skin. Andasparagus( 芦笋 ) could fix a broken spine(脊柱).Now, Pelling and his team are trying hard to put these crazy ideas into reality.48.

渔人甚异之，复前行，欲穷其林。
林尽水源，便得一山，山有小口，仿佛若有光。
便舍船，从口入。
初极狭，才通人。
复行数十步，豁然开朗。
土地平旷，屋舍俨然，有良田美池桑竹之属。
阡陌交通，鸡犬相闻。

After more than 30 years of development, the company has now beaten Apple and become the world’s second - largest maker of smartphones behind Korea’s Samsung. It has also become the world’s largest supplier of 5G.But recently, Huawei faced some difficulties. The US government ordered a ban（禁止）on its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the US government planned to stop selling parts and services to Huawei, which was believed to hurt Huawei’s business.“We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information,” Ren Zhengfei, Huangwei’s founder and president said. “The ban from the US would have little effect on our company. Huawei has enough ability to deal with the problems,” Ren added.In an interview several years ago, Ren Zhengfei said，“I started Huawei with only 20, 000 yuan, but now it has become a $100 billion company. The experience was not as romantic as you imagine.”Facing the ban of the US, Huawei is growing. Huawei’s smartphone sales around the world rose a lot compared to last year. At the same time, sales from both Samsung and Apple fell. So far, Huawei has grown into the world’s largest telecommumication equipment（电信设备）supplier, selling in 170 countries. It may beat Samsung as the largest smartphore maker in the near future.24．What is the corret order of the world’s largest smartphone maker according to the passage? A．Apple - Huawei - Samsung.B．Huawei - Apple - Samsung. C．Samsung - Apple - Huawei.D．Samsung - Huawei - Apple.25．What was the excuse of the US government to order a ban on Huawei?A．Huawei’s sales in America were growing faster than Apple.B．Huawei’s smartphones were not good enough to use.C．Huawei collected information for the Chinese government.D．Huawei refused to supply services to the US government.26．What does Ren Zhengfei mean by the underlined（划线的）sentence?A．Huawei’s development was a romantic story.B．Huawei went through hard times before its success.C．Success belonged to romantic people.D．People should work hard to achieve their goals.27．How does the writer support his prediction about Huawei’s bright future?a. By listing numbers.b. By telling stories.c. By comparing.d. By giving the definition（定义）.A．a c B．a b C．a d D．b cCNature and culture are often seen as opposite ideas. What belongs to nature cannot be the result of human activities and on the other hand, cultural development is achieved against nature. However, this is not the only opinion on the relationship between nature and culture. Studies in the development of humans suggest that culture, whether taken as an effort against nature or a natural effort, is part of the development of the human species(物种).Several modern writers saw the process of education as a struggle(斗争) against human nature. We are born with wild natures, such as eating and behaving in a disorganized way or acting selfishly. Education uses culture as a way to get us out of our widest natures; it is thanks to culture that the human species could learn to adapt(适应) , progress and raise itself above and beyond other species.Over the past century and a half, however, studies in the history of human development have shown that the formation of culture is part of the biological adaptation. Consider, for example, hunting(打猎) . It seems to be an adaptation, which allowed humans to move into new and different areas, opening up the opportunity to change living habits. At the same time, the development of weapons(武器) is related to that adaptation-from rocks and stones to a set of hunting tools, and from hunting tools to rules relating to the proper use of weapons. Hunting also seems to be responsible for a whole set of bodily abilities, such as balancing on one foot. Just think of how this very simple thing is closely related to dance, a key expression of human culture. It is then clear that biological developmentand cultural development are closely tied.The transmission of culture seems to be directly related to what’s in our blood. Just as snails carry their shells, so do we bring along our culture. However, culture is also passed on among people of the same time or among people belonging to different populations. We can learn how to make jiaozi even if we were born from Russian parents in Paris just as we can learn how to speak English even if none of our family or friends speak that language.28．What is Paragraph 2 mainly about?A．Culture belongs to human nature.B．Nature teaches humans how to adapt.C．Humans are supposed to be well organized.D．Education pushes the human species to progress.29．Why does the writer talk about hunting in Paragraph 3?A．To suggest some possible ways of changing living habits.B．To stress the importance of tools in humans’ struggle for life.C．To show how culture develops as humans adapt to the environment.D．To explain why there is a need to call for the proper use of weapons.30．The word “transmission” in Paragraph 4 probably means “________”.A．system B．spread C．start D．spirit31．What is the writer’s opinion on the nature-culture relationship?A．Culture and nature are separate yet balanced.B．Culture depends much on nature to progress.C．Nature and culture are different but connected.D．Nature follows the unwritten rules set by culture.DIn 1987 a small company named Huawei was started in Shenzhen. After more than 30 years of development, the company has now beaten Apple and become the world’s second largest maker of smartphones. It has also become the world’s supplier (供应者) of 5G. In China and even in the world, Huawei is a wonder. Although it started producing mobile phones not many years ago, it has become one of the most famous phone companies.But recently, Huawei faces some difficulties. The US government made a law to stop its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the US government planned to stop selling parts and services to Huawei. They believed that Huawei’s business would be hurt this way.“We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information,” Ren Zhengfei, Huawei’s president said. “The law wouldhave little effect on our company. Huawei has enough ability to deal with the problems,” Ren added.In an interview several years ago, Ren Zhengfei said, “I started Huawei with only £4000 at the beginning, but now it has become a 100 billion company. The experience was not as romantic as you imagine.”Facing the law of the US, Huawei is growing. Huawei’s smartphone sales around the world rose 50 percent compared with a year earlier in the first three months of 2019. At the same time, sales from both Samsung and Apple fell. So far Huawei has grown into the world’s largest telecommunication equipment supplier (供应商), selling in 170 countries. It may beat Samsung as the largest smartphone maker in the near future.32．How many kinds of smartphones are mentioned in total in this passage?A．One.B．Two.C．Three.D．Four.33．Which of the following sentences is TRUE according to the passage?A．Huawei collected the information for the Chinese government.B．Ren Zhengfei started Huawei with only £4000 in 1987.C．Huawei has beaten Samsung, a South-Korea phone maker so far.D．Huawei has developed its business smoothly.34．What does the underlined word “romantic” in Paragraph 4 mean in Chinese?A．浪漫的B．现实的C．成功的D．麻烦的35．The last paragraph mainly tells us ________.A．Huawei has become one of the most famous phone companies.B．Huawei has become the largest maker of smartphones in the world.C．Huawei has got into some systems of the US.D．Huawei is full of hope and must succeed in the future.第二节（共5小题；每小题2.5分，满分12.5分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
