The new garbage sorting regulation has taken effect in Shanghai starting July 1. Many citizens are still confused about the classification of the four different types of trash. Thankfully, authorities have released an official guideline to clarify the new rules. The guideline, published by the Shanghai Greenery and Public Sanitation Bureau, provides a rather clear definition on the four kinds of waste: recyclable waste, hazardous (有害的) waste, household food waste and residual (剩余的) waste. Hazardous waste, as the name suggests, includes assorted poisonous materials like used batteries, light bulbs, out-of-date medicines, paint and pesticides. Household food waste, which is translated to “wet trash” in Chinese，refers to food leftovers, rotten food, pet food, fruit peels, remains of TCM herbs (中药) and flowers. Paper, plastic, glass, metal and textiles (纺织品) are counted as recyclable waste. The definition of residual waste is a little confusing. Anything that is not listed above belongs in this category. As specific as the new guideline is, residents still have a hard time sorting trash correctly and are finding it challenging to memorize them all. For instance, both plastic bottles and bubble tea or coffee cups are plastic materials. However, the former falls to the category of recyclable waste and the latter belongs to residual waste. To save the hassle, some netizens have come up with their own ways to sort trash. “We should do this from a pig’s angle,” commented one netizen. “Those edible (可食用的) for pigs are household food waste. Those even pigs don’t want to eat are residual waste. If a pig consumes something and dies of it, then something must be hazardous waste. Those which can be sold and the money we gain can be used to purchase pigs are recyclable waste.” The new regulation has gone into effect on July 1. Those who do not sort their trash properly will be fined RMB200. 1.What do the old thrown-away sweaters belong to? A.Residual waste. B.Hazardous waste. C.Recyclable waste. D.Household food waste. 2.What does “wet trash” have in common? A.They are completely wet. B.They all come from plants. C.They can give off bad smell. D.They can break up easily. 3.What is the tone of the netizen? A.Humorous. B.Serious. C.Delightful. D.Uncertain. 4.What is the main idea of the text? A.Shanghai bans four sorts of garbage. B.Shanghai launches garbage sorting enforcement. C.Citizens in Shanghai still question garbage sorting. D.Citizens in Shanghai welcome the garbage sorting policy.

In the old days, when you had to drive to a movie theater of to to a video store to get some entertainment, it was easy to see how your actions could have an impact om the environment.You were hopping into your war, driving across town and coughing out emissions（排放）and using gas all the way. But now that we’re used to staying at home and streaming movies, we might get a little cocky. After all ,we’re just picking up our phones or maybe turning on the TV. You’re welcome.Mother Nature. Not so fast, says a recent report from the French-based Shit Project. Watching a half-hour show would lead to 3.5 pounds of CO2 emissions. That’s like driving 3.9 miles. According to "Climate Crisis: The Unsustainable Use of Online Video," digital technologies are responsible for 4% of greenhouse gas emissions, and that energy use is increasing by 9% a year. Stored in data centers, videos are transferred to our terminals such as computers, smart phones, etc. via networks: all these processes require electricity whose production consumes resources and usually involves CO2 emissions. In the European Union, the Eureca project lead scientist, Rabih Bashroush, calculated that 5 billion downloads and streams of the song "Despacito" consumed as much electricity as the countries of Chad, Guinea-Bissau, Somalia, Sierra Leone and the Central African Republic used in a single year. Streaming is only expected to increase as we become more attached to our devices. Online video use is expected to account for 80%of all internet traffic by 2022 according to CISCO. By then, about 60% of the world's population will be online. You're probably not going to give up your streaming services, but there are things you con do to help lessen the impact of your online use. Here are some tips: ※Disable autoplay for video on social media. ※Stream over Wi-Fi, not mobile networks. ※Watch on the smallest screen you can. ※Don’t use high-definition（高清）video on devices. 1.It can be inferred from paragraph 2 that people think . A.they should welcome Mother Nature B.watching movies at home is more fun C.it is inconvenient to drive to a movie theater D.streaming at home avoids possible emissions 2.We may learn from the text that . A.3.9 miles may produce 3.5 pounds of CO2 B.digital technologies account for 4% of electricity use C.Online video use makes up 80% of all internet traffic D.60% of the world’s population watch videos online 3.Why are the five countries mentioned in paragraph 4? A.To praise their energy-efficient practice. B.To prove the poverty of the five countries C.To stress the popularity of the song “Despacito” D.To show the high energy use of downloads and streams 4.How can people help to save energy when streaming? A.Use high-definition videos. B.Turn off video autoplay C.Stream over mobile networks. D.Watch movies on bigger screens.

As they reach school age, about 90 percent of children will have experienced a condition in which fluid (液体) fills the middle ear, muffling (使模糊) sound and sometimes causing infection. The fluid usually clears on its own, but if not, it can lead to a painful ear infection called acute otitis (中耳炎) media. In some cases the fluid can persist for more than a year, causing hearing loss during this period, and slowing down their development of language and social skills. Diagnosis usually requires a visit to a specialist—but researchers have now developed an app that detects this fluid just as accurately, with only a smartphone and a paper funnel (漏斗). Doctors typically detect the problem by peering into the ear for a visual assessment. Yet, this method has only a 50 percent accuracy rate. “Right now, if you bring your child to a pediatrician, or to any urgent care family doctor, the way they look at whether or not there’s fluid in the middle ear is by looking at the eardrum,” says Sharat Raju, a surgeon in the department of head and neck surgery at the University of Washington. For a cheaper and more accessible alternative, researchers at the University of Washington turned to smartphones. First the user follows a template to cut and tape a piece of paper into a funnel, which can be placed between a smartphone and the patient’s ear. Next the app plays a chirping sound through the phone’s speaker; the sound waves bounce off the eardrum and hit the phone’s microphone, where they register and are analyzed by the app. An eardrum with fluid behind it will vibrate (振动) differently than if the middle ear is full of air, as it normally is. To develop the app, the researchers first played chirps for patients with and without fluid in their ears. They recorded the echoes (回音), which indicate the eardrum’s mobility. Then they used a machine learning model to classify the returning sound waves, determining which audio characteristics indicated a normal ear and which suggested the presence of fluid. Once they tested the app on 98 children, ranging from 18 months to 17 years old, at Seattle Children’s Hospital. It correctly detected fluid in 85 percent of cases, and correctly identified fluid-free ears in 82 percent. The researchers are currently trying to get FDA approval for the app, and have founded a company to commercialize it. They hope to make it available by the end of the year, to help parents track children’s ear health at home. 1.What do we know about the fluid from the first paragraph? A.It is mostly part of children’s growth. B.It is unavoidable for any child. C.It is a permanent physical condition. D.It is beyond any medical means. 2.What does the underlined word “pediatrician” refer to in Paragraph 3? A.A hospital. B.A specialist. C.A relative. D.An app. 3.What is the fourth paragraph mainly about? A.The application of the app. B.The causes of the kid’s ear problem. C.The purpose of developing the app. D.The experiment of the smartphone. 4.What do the researchers expect of the app? A.It will upgrade the medical technology. B.It will hit the market in the near future. C.It will help children do better academically. D.It will save doctors medical operations.

Put on new set of gasses for a new view Today I visited San Francisco’s modern-art museum. I was there to see a new exhibit about spaceflight.1.I like to “visit” this particular painting every time I go to the museum not only because it evokes（唤起）strong feelings, but because I always find something new. There's real pleasure to be found in revisiting a museum replaying a game or rewatching a movie. Some of that enjoyment comes from the feeling of familiarity of course.2..There’s always plenty more to see, hear, taste, smell, feel, of understand the second or third time around. But how do you discover the exciting new thing in the familiar? One way is approaching whatever task is at hand by searching for the things that you didn't see in the first time around. First, recognize that everything is always changing.3.Second, remove judgment from the experience, if possible, and just observe what's new. For example, look for the ways in which a change in your neighborhood is interesting or exciting. 4.That could mean removing sugar, coffee, a certain kind of media from your life for a specified time. Once the break is over, that same thing will have more of its former interest or excitement.5.So is true that novelty is fun, but given enough of a break in between, repeated experiences regain that initial excitement. A. Repeated experiences like this are valuable. B. Visiting a new country brings fresh experience. C. Coffee will never taste better if you quit it for a month. D. But the piece of art that made me cry was a familiar one. E. But it also comes from noticing new things in what is so familiar. F. So the second experience is never exactly the same as the first one. G. Another way is changing your routine and taking a break of some kind.
