11、light technology. A light source activates the doors handle coating, telling it to start cleaning. It can minimize the risk of infection by contact and improve the cleanliness of a space. How it worksThe working principle of the product is that a thin advanced photocatalytic coating can effectively
12、decompose bacteria ( 细 菌 ) on the surface of a substance. A consistent UV light sourceinside a transparent glass door handleis required to activate the doors handle coating on the outer surface for disinfection, so a generator is used to provide electricity to light up a UV LED lamp by the motion of
13、 an opening and closing door. Then, the door handle can clean by itself.Design processWe made the first version by using stainless steel. However, it caused the door handle to be heavier. Then, we tried aluminum, which made it light and easy to fix. We also improved the generator output which effect
14、ively turned energy from door movement into a light source.How it is differentOur innovative design is simple, effective, and attractive. It has an elegant smooth shape, and its minimalist appearance stands out in todays world of inventions. Nowadays, people use chemical cleaning materials to clean
15、up public areas but it harms the human body. Our design can be used for a long time and is effective. It can self-clean after each use. In the door lock and door handle market, it is a unique design because there are no similar products.Future plansIn the future, we will commercialize the product an
16、d hope that it can compete on the market with similar products. We are going to connect with public properties, for example, shopping malls, hotels, hospitals and public restrooms, where the risk of spreading infection is higher.AwardsIn addition to winning the James Dyson Award, it has also receive
17、d the Gold Award, and in 2016, it was featured in the 44th International Geneva Inventions Exhibition.1. How does the self-cleaning door handle function?A. It controls the door movement automatically.B. It minimizes the risk of infection by less contact.C. Chemical cleaning materials are used to cle
18、an it up.D. The light source tells the door handle coating to clean itself.2. Compared with the first version of the product, the present one is _.A. safer and cheaperB. cleaner and easierC. less heavy and more effectiveD. more attractive and expensive3. What do we know about the new invention accor
19、ding to the passage?A. It has been widely used in public areas.B. It has received recognition for its innovation.C. It is quite competitive among similar products.D. It will replace traditional chemical cleaning materials.BRome wasnt built in a day. And neither was the Roman subway system. Undergrou
20、nd work is slow going, because construction workers often meet with frescoes(壁画) and other valuable stone foundations thousands of years ago. And a few years ago, they found the wooden foundations of a luxurious porch from a Roman building.So local archaeologists called in Mauro Bernabei of the Nati
21、onal Research Council of Italy. Hes a dendrochronologist: someone who analyzes tree rings, which give age and environmental information.We have to study wood because its full, really full, of information! Bernabei and his team found that the wooden planks were oak(橡木). But the woods origin was harde
22、r to determine. So they compared the tree rings in the oak floor to those available in libraries of tree rings that contain timber fromall over Europe. And they found a match for the Roman woodfrom the Jura region of eastern France, more than 600 miles away.The researchers also determined that it wa
23、s used in about 40 to 60 B.C. And some came from trees already up to 300 years old when they were cut down. The details are in the journal PLOS ONE.The discovery is the first clear evidence of oak from north of the Alps being used to build ancient Rome. And its a reminder that the Romans had a compl
24、ex trading network. These trees, for example, likely floated down two rivers, across the Mediterranean and up another river to Rome.Bernabei says Roman archaeologists usually destroy ancient woodits not as valuable as jewelry and vases and frescos. But hes hoping this study might change their minds.
25、Save the wood, yes! And call me,if you dont want to saveplease, call me!He says.4. Why does the subway in Rome go slowly?A. It is hard to dig up the earth in Rome.B. There are many ancient ruins buried here.C. It is very dangerous to work too fast in RomeD. The Roman are not experienced in building
26、subways5. What can people learn from the wood foundations?A. The wealth in ancient RomeB. The trading information of ancient RomeC. The culture of ancient RomeD. The social relations of ancient Rome6. What does the underlined word in paragraph 4 refer to?A. The stoneB. The subwayC. The French woodD.
27、 The Roman foundation7. What is the main idea of this passage?A. Scientists found some information about ancient RomeB. Wood was not as valuable as stones in ancient RomeC. Only the rich people in ancient Rome could use woodD. Ancient Rome could have a rich trading network.CIts no secret that inhali
28、ng(吸入) smoke is bad for your lungs. But now, scientists are suggesting smoke may also carry and spread infectious diseases.The theory,published in Science Magazine, is based on research that found wildfire smoke is teeming with thousands of species of microorganisms. Some of these microorganisms, in
29、cluding bacteria and fungal spores(真菌孢子), are known to cause disease.The new research suggests that when a wildfire burns plant or animal matter and disturbs soils, it exposes thousands of species of bacteria and fungi(真菌) that otherwise might not easily become airborne(空气传播的). You might think the h
30、igh heat from fire would kill these organisms, butone study cited in the article found that some bacteria even multiply post-fire. Scientists say the organisms latch onto smoke particulates(微粒), allowing them to travel thousands of miles across continents.Dr. Peter Chen, director of the Division of
31、Pulmonary and Critical Care Medicine at Cedars-Sinai Medical Center in Los Angeles, is intrigued by the theory but somewhat skeptical that the microorganisms in smoke would actually cause infections. Many bacteria and fungi dont cause lung infections, says Chen, but its certainly possible that a sig
32、nificant amount could worsen symptoms in someone with a pre-existing lung condition.I always thought it was the particulates in smoke that were causing these issues, says Chen, But when I read this, I started thinking: Could it be the microorganisms that are also worsening existing illness?Whether t
33、he microbes in smoke actually cause infection or simply worsen potential respiratory(呼吸的) issues, the article raises a new health threat that is certainly alarming, saysKelsey Jack, an associate professor of environmental and development economics.This is especially true for lower-income populations
34、, Jack says, because people with fewer means are often more exposed to the environment. If smoke is affecting the air quality in a certain area, the people who work outside, or who have to go to the office on foot or by bike, will inhale more smoke than those who drive.But until more research is don
35、e, Chen says the best thing people can do is just follow existing recommendations whenair quality is poor including staying indoors, keeping windows and doors closed, usingHEPA filters(过滤器)and running air conditioning.8. What can we know about the microorganisms from paragraph 2?A. They could be kil
36、led by high heatB. They could possibly travel through air by themselvesC. They could reproduce in large numbers after fires.D. They can easily attach themselves to smoke particulates9. How do most microorganisms affect people according to Dr. Peter Chen?A They will causes lung infections.B. They mig
37、ht worsen lung diseaseC. They will destroy living environments.D. They might damage respiratory system10. Why are low-income people suffering more than others?A. They live in poor areas.B. They drive to and from workC. They have suffered from lung diseaseD. They are exposed to polluted air more freq
38、uently.11. What does the last paragraph mainly talk about?A. Results of the new researchB. Disagreements between the author and Chen.C. Suggestions on dealing with poor air qualityD. Benefits of preventing smoke from polluting the airDIt should be one of the main goals in todays society to reduce pl
39、astic consumption. Though many of us believe that recycling will solve the problem, and continue using plastic, its actually the opposite. In 2013, 254 million tons of trash was produced in the U.S. alone, and only around 30% was recycled. This means that the rest ended up in a landfill and will sta
40、y there for up to 1000 years.Recently, China has stopped importing trash from all over the world. Before this, over 30% of the worlds waste would end up in China, causing a popular belief that Asian countries are those responsible for creating the majority of the waste in the world. Now, Asian count
41、ries, including Vietnam and Thailand, are looking for new ways to avoid plastic. One of those ideas was a new, eco-friendly way to pack their goods by avoiding plastic packaging.One of the Perfect Homes Chiangmais team members noticed a creative way to reduce plastic that a supermarket called Rimpin
42、g Supermarket was using and decided to take photos of their shelves with his phone. Little did he know that people from all around the world would absolutely love this idea.“I just popped in to get a few items while we were waiting to sign some contracts(合同) with our lawyer, who was delayed. When I
43、noticed the vegetables wrapped in banana leaves and simply liked the idea, I took a few pictures and posted them online” he said.With more than 3.5 million views and over 17 thousand shares, the idea became something people can encourage more supermarkets to implement(贯彻).Some have noticed that not
44、everything on the shelves is completely plastic-free, to which the supermarket responded that they are taking one step at a time, but its not that easy. Many products come to the supermarkets pre-packaged and many companies are interested in wrapping their produce in plastic since it is the cheapest
45、 and the easiest option. Its now up to the shoppers to show the supermarket which they prefer. If every one opts for the banana leaf packaging, they will stop stocking the items in plastic.12. What can we infer about recycling from paragraph 1?A. The author thinks highly of recyclingB. The US did a
46、great job in recycling in 2013C. Recycling has failed to solve the plastic problemD. Recycling helps a lot in reducing plastic consumption13. Why did the man go to Rimping Supermarket ?A. To take photos of their shelvesB. To meet with their lawyer thereC. To buy some itemsD. To sign some contracts w
47、ith the supermarket.14. What does the underline phrase“ opts for ”in the last paragraph probably mean?A. DoubtsB. DiscussesC. DislikesD. Chooses15. What is the best title of the passage?A. Leaf Packaging Goes ViralB. Reducing Plastic ConsumptionC. Recycling Avoids Plastic PackagingD. A Good Option M
