    A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces(熔炉) that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.

    The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.

    After the explosion, gravity pulls in what's left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so solid that a teaspoon of matter from it weighs billion of pounds.

    The more the star shrinks(收缩), the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is unbelievably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!

    That's what we know about black holes. What we don't know is this: What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.

    But if the black hole doesn't keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a "white hole" in a different universe. As the black hole swallows(吞噬) light, the white hole shines brightly--somewhere else. But where? A different place, perhaps, or a different time--many years in the past or future.

    Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed(挤压). So far the time being, black hole must remain a mystery.

    Black holes are a mystery--but that hasn't stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth's energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste--a sort of huge waste disposal(处理) in the sky!

(1)、When the star begins to die ______.
A、there is no fuel left in it B、a huge explosion will happen C、its outer layer goes into space first D、it doesn't give off light any longer
(2)、Which of the following doesn't help produce a black hole?
A、The dying star shines very brightly. B、The light can't go out of the star. C、The star becomes smaller and smaller D、The gravity inside the star is very strong.
(3)、The black hole ______.
A、continues becoming smaller and smaller all the time B、goes into another universe and becomes a white hole C、will appear at another place at a different time D、can pull in everything we know of in the world
(4)、What's the best title for this passage?
A、A New Scientific Discovery: Black Holes B、What Are Black Holes? C、What Are Black Holes? How Do Black Holes Come Into Being? D、Travel Through A Black Hole

    For many people who live in cities, parks are an important landscape. They provide a place for people to relax and play sports, as well as a shelter from the often severe environment of a city. What people often overlook is that parks also provide considerable environmental benefits.

    One benefit of parks is that plants absorb carbon dioxide and give off oxygen. According to one study, an acre of trees can absorb the same amount of carbon dioxide that a typical car emits in 11,000 miles of driving. Parks also make cities cooler. Scientists have long noted what is called the Urban Heat Island Effect: building materials such as metal and concrete (混凝土) absorb much more of the sun's heat and release it much more quickly than trees and grass. Because city landscapes contain so much of these building materials, cities are usually warmer than surrounding rural areas. Parks and other green spaces help to lessen the Urban Heat Island Effect.

    Unfortunately, many cities cannot easily create more parks. However, cities could benefit from many of the positive effects of parks by encouraging citizens to create another type of green space: rooftop gardens. While most people would not think of starting a garden on their roof, human beings have been planting gardens on rooftops for thousands of years. Some rooftop gardens are simple container gardens that anyone can create with the investment (投资) of a few hundred dollars and a few hours of work.

    Rooftop gardens provide many of the same benefits as other urban parks and garden spaces, but without taking up the much-needed land. In the summer, rooftop gardens prevent buildings from absorbing heat from the sun, which can significantly reduce cooling bills. In the winter, gardens help control the heat that materials like brick and concrete release so quickly, leading to savings on heating bills. Rooftop vegetables and herb gardens can also provide fresh food for city settlers, making their diets healthier. Rooftop gardens are not only something everyone can enjoy but also a smart environmental investment.

    About three decades ago, China was known as the “Bicycle Kingdom”. But later on, bikes were replaced by their fuel-powered competitors.

    But recent months have seen a recovery of the humble bike across China, with an increasing number of people choosing cycling instead of driving to schools, to workplaces or to do sightseeing. The introduction of bike-sharing schemes, pioneered by start-ups like Ofo and Mobike, has brought the trend to a new level.

    People can unlock the shared bikes by simply using their smart phone. The bikes are equipped with GPS and can be left anywhere in public for the next user. They're popular among many Chinese people as they provide an effective solution to the “last mile” problem, which refers to the final leg of a person's journey.

    “In places where the subway doesn't extend, where it's difficult to change from one kind of transport to another, it's so easy to get where you want to go with Mobike,” Hu Hong. 29, told AFP. She pedals(骑车)to her Shanghai real-estate job.

    However, the schemes have also led to problems such as illegal parking, vandalism(故意毁坏)and theft. Last month, two nurses in Beijing were placed under administrative punishment for five days for putting locks on two shared bikes. And in December, a man who stole a shared bike was sentenced to a 3-month detention(拘留), and fined 1,000 yuan by the Shanghai Minhang People's Court.

    “Bike-sharing is a greener method of transportation and provides a user-friendly experience.” said Liu Xiaoming, vice-minister of transport.

    “But it's a combination of online and offline business. Operators are usually strong in online services, but lack offline business experience, which causes problems.”

    Skateboarding is an action sport which includes riding and performing tricks using a skateboard, as well as an activity for fun, an art form, an entertainment industry job, and a method of transportation. In 2016, it was announced that skateboarding will be represented at the 2020 Summer Olympics in Tokyo, Japan.

    There are various theories about the origins of Skateboarding, but it is generally held that the sport began in the 1940s on the west coast of the USA when metal wheels were attached to a narrow wooden board. In the 1950s, plastic replaced metal as the material of choice for the wheels, and the first "Roller Surfboard" become commercially available, which in turn developed into the skateboard that we know today. The sport was a big hit with the younger generation and grew in global popularity in the 1980s and 1990s. Since the late 1990s, skateboarding has become an important part of street culture.

    However, skateboarding has raised heated discussions in areas where the activity, although legal (合法的), has damaged stone works, steps, benches, and parks. Certain cities oppose the building of skate parks in their neighborhoods, for fear of increased crime (犯罪) and drugs in the area. The disagreement between the old image of skateboarding and a newer one is quite obvious: magazines such as Thrasher describe skateboarding as dirty, and still firmly tied to punk (朋克), while other publications, Transworld Skateboarding as an example, paint a more different and controlled picture of skateboarding. As more professional skaters use hip hop, or hard rock music in their videos, many urban youths, hip-hop fans and hard rock fans are also drawn to skateboarding, weakening the sport's punk image. Besides, group spirit influences the members of this community. In presentations of skateboarding, the evidence of crime is absent, and no attempt is made to tie extreme sports to any kind of illegal activity.

    The good news is that efforts have been made to improve recognition of the cultural heritage as well as positive effects of skateboarding in cities. By raising £790,000, the Long Live Southbank initiative managed to stop the destruction of a forty years old spot in London due to urban planning, a rescuing operation whose effect extends beyond skateboarding. The presence of skateboarders on this public space keeps the area under nearly constant watch and drives homeless people away, increasing the feeling of safety in the area. The activity attracts artists such as photographers and film makers, as well as a significant number of tourists, which in turn drives economic activity in the neighborhood.

    No fashion event attracts the world quite like the Victoria's Secret Fashion Show. In November 2017, more than 55 models descended upon Shanghai for the lingerie(内衣)maker's first show in Asia. Victoria's Secret cast eight Chinese models for the show, including Liu Wen, double the number that walked in 2016.

    Liu Wen, a Chinese fashion model, started her modeline career in 2005 after competing in the reality TV show New Silk Road World Model Contest. Although she did not win the competition, Liu soon began working full-time as a model, eventually becoming a national success story after working with fashion magazines like Vogue and Harper's Bazaar that are popular in China, In 2007, she was signed to the Marilyn agency, and has since walked for Burberry. Givenchy, Chanel, Tom Ford, Proenza Schooler and Tommy Hilfiger.

    Liu walked a record 74 shows in New York, London, Milan and Paris for the autumn/ winter 2009 season, followed by 70 for spring/summer 2010, making her the second most-booked catwalk model that year. She has also achieved 15 international Vogue covers to date.

    In 2009, Liu became the first woman of Chinese origin to walk in the Victoria's Secret Fashion Show. Liu also participated in the 2010—2012 shows. She returned to the Victoria's Secret runway again in 2016.

    In the past, Liu has said that after modeling she might enjoy working as a stylist or, were the opportunity to arise, as an actress-she feels that modeling and acting have much in common, but for now she enjoys modeling and working in the fashion industry. She has stated that she knows that, as a career choice, working as a fashion designer or stylist would be “very hard work”, but she is now more seriously considering becoming a stylist because she would like “to share her fashion style -tomboyish, vintage, and comfortable-with the world”.
