21、have been sorting their trash believing that most plastic could be recycled. But the truth is that the vast majority of all plastic produced cant be or wont be recycled. In 40 years, less than 10% of plastic has been recycled.A news programme Frontline, by NPR and the PBS, found that oil and gas com
22、panies- the makers of plastic-have known that all along, even as they spent millions of dollars telling the American public the opposite. The plastics industry officials said the industry is providing money for new technology that they believe will get recycling plastic up to scale. The goal, they s
23、aid, is to recycle 100% of the plastic they make in 5 years.But the more plastic is recycled, the less money the industry will make by selling new plastic. And those profits have become increasingly important. Companies have told shareholders （股东）that profits from using oil and gas for transport are
24、 expected to decline in coming years with the increasing use of electric cars. The industry leaders expect oil and gas demands from the chemical industry will be much greater than the demand from the transport side in the coming decade. Plastic production overall is now expected to rise three times
25、by 2050, and once again, the industry is spending money on advertisements and public relations to promote plastic recycling.Plastic is now more common than its ever been and harder to recycle. Gas prices remain at historic lows, making new plastic cheaper than recycled plastic. And the industry now

29、 More?D. Plastic Products or Substitutes?CNew App Helps People Remember FacesLarge gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn peoples names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy experts recommend p
30、roceeding with caution.The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. “It breaks down these social barriers we all have when meeting somebody,” says Barry Sandrew, who created the app and
31、tested it at an event attended by about 1,000 people.After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points h
32、is or her phone camera at an attendees face, the app identifies the individual, displays the persons name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the apps creators say it automatically deletes users data after an
33、 event.Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the apps creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended conseque
34、nces down the road with that information being used in another context that might come back to bite you.”The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or “face blindness,” a condition that prevents people from recognizing individuals they have me
35、t. To use this app, a person first acquires an image of someones face, from either the smartphones camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a users p
36、hone, according to the team behind the app.28. SocialRecall is used to _.A. take photos B. identify peopleC. organize events D. make friends29. SocialRecall helps people with prosopagnosia by _. A. giving names to the photos kept in their smartphonesB. collecting information previously entered in th
37、e phoneC. providing the information of a person when they first meetD. showing the persons information when it spots a stored face 30. What can we learn about SocialRecall from the passage?A. It may put peoples privacy at risk.B. It has caused unintended consequences.C. It can prevent some communica
38、tion disorders.D. It is praised by users for its protective measures.DFollowing the outbreak of the novel coronavirus pneumonia (NCP), also named COVID-19 by WHO, there is a general fear of the unknown virus as its full effects remain to be seen. Fever, coughing, sore throat, difficulty breathing th
39、e NCPs symptoms are similar to the common cold or the flu, but its potentially more dangerous.Viruses could be deadly, like HIV and Ebola. But what are viruses? How can they cause so much trouble?Viruses are non-living organisms ( 有机 体) approximately one-millionth of an inch long. Unlike human cells
40、 or bacteria, they cant reproduce on their own. Instead, they invade the cells of living organisms to reproduce, spread and take over.Viruses can infect every living thing from plants and animals down to the smallest bacteria. For this reason, they always have the potential to be dangerous to human
41、life. Sometimes a virus can cause a disease so serious that it is fatal. Other viral infections trigger no noticeable reaction.Viruses lie around our environment all of the time, waiting for a host cell to come along. They can enter our bodies by the nose, mouth, eyes or breaks in the skin. Once ins
42、ide, they try to find a host cell to infect. For example, HIV, which causes AIDS, attacks the T-cells of the immune system.But the basic question is, where did viruses first come from? Until now, no clear explanation for their origin exists. “Tracing the origins of viruses is difficult”, Ed Rybicki,
43、 a virologist (病毒学家) at the University of Cape Town in South Africa, told Scientific American, “because viruses dont leave fossils and because of the tricks they use to make copies of themselves within the cells theyve invaded”.However, there are three main hypotheses (假说) to explain the origin of v
44、iruses. First, viruses started as independent organisms, then became parasites ( 寄 生 者 ). Second, viruses evolved from pieces of DNA or RNA that “escaped” from larger organisms. Third, viruses co-evolved with their host cells, which means they existed alongside these cells.For the time being, these
45、are only theories. The technology and evidence we have today cannot be used to test these theories and identify the most plausible explanation. Continuing studies may provide us with clearer answers. Or future studies may reveal that the answer is even murkier (含糊不清的) than it now appears.31. What ca
46、n we learn about viruses from the text?A. Viruses have nothing to do with the common cold.B. Viruses are really small living organisms.C. Viruses cant reproduce unless they find a host cell.D. Viruses enter our bodies mainly through the mouth, nose and hair. 32. Which of the following might explain
47、the origin of viruses?A. They evolved from the fossils of large organisms.B. They evolved from parasites into independent organisms.C. They evolved from the T-cells in animals.D. They evolved along with their host cells.33. The underlined word “plausible” in the last paragraph probably means_.A. rea
48、sonable B. commonC. creative D. unbelievable34. What can we conclude from the text?A. Viruses live longer in human host cells than in animals. B. Viruses will become more like bacteria as they evolve.C. It may take a long time to understand the origin of viruses. D. The author is optimistic about fu

50、eading?Of course, when we are young, our parents and teachers inspire us by introducing us to characters that we love or hate. As a child, I loved books written by Roald Dahl, such as Charlie and the Chocolate Factory and The Twits. 36. They are popular with children even today, despite competition
51、from contemporary authors.One modern-day childrens author is J. K. Rowling, whos known for her books about the wizard, Harry Potter. 37.

The width of a cracker. Its also the amount that the Atlantic Ocean is expanding every year.Now when youre talking about
57、 an ocean that is 4,830 kilometres (3,000 miles) wide at its largest point, 4 centimetres (1.6 inches) is not much. But it is happening. So naturally, scientists want to know why.Thanks to a new study, researchers think that they have the answer why. You could even call it a hot take. As in hot magm
58、a, or molten rock, deep under the ocean floor!The study suggests that the expansion is being caused by magma(岩浆) bubbling up from under an underwater mountain range called the Mid-Atlantic Ridge. Lets start with what that ridge is.Basically, the Mid-Atlantic Ridge is the seam between some very large
59、 tectonic plates. The ridge is also known as a plate boundary. As weve discussed before here, tectonic plates are essentially the platforms that our continents rest on. They are large pieces of the crust that are always moving in slow motion.This movement is what causes earthquakes, for example. And
60、 the areas where the plates meet are where we tend to find things like mountains and volcanos, as well.In this case, as the magma bubbles up from the mantle(地幔) below the crust, it is pushing the edges of both plates out of the way. As a result, the ocean is slowly getting wider.This is a new findin
61、g. Before the study, scientists thought that the plates were being pulled apartthey were being dragged away from the ridge by forces occurring on either side of the ocean, not from in the middle.Scientists still believe that this pulling motion is happening. It is just that now, they feel that the b
62、ubbling magma is an important force as well. There is push and pull.The scientists behind this study have been quick to point out that their research is only looking at a small cross-section of the ridge. Its like a slice across it. What is happening right along this slice, may not be happening the
63、same way up and down the entire ridge. But it is still really useful informationand how they got it is pretty cool.Back in 2016, a research ship traveled to a very quiet spot directly over the ridge. Over five weeks, the crew dropped 39 seismometers on to the ocean floor. These devices allow them to
64、 listen to the activity of the tectonic plates and what was beneath it. Its like what a stethoscope does with your heartbeat, but for the planet. A year later, they retrieved the devices and looked at the data.Then it was back to the lab to try and piece together what they learned. In the end, they
65、have added to our understanding of how and why the Earths surface constantly moves. Even if it is only by about a little bit each year!40. What is causing the expansion of Earths second largest ocean?41. What does the underlined phrase “This movement” refer to?42. Please decide which part of the fol
66、lowing statement is false, then underline it and explain why.Scientists find that it is the magma below the crust that is pushing the edges of both plates out of the way to cause the ocean to slowly get wider, but not the forces occurring on either side of the ocean pulling the plates apart.43.
