The dream of the flying car could come down to earth soon as several start-ups like Chinese EHANG and Uber are developing so-called "passenger drones（无人机）"-self-flying drones big enough to ferry individual commuters around town-which could shrink commute（上下班往返） times from hours to minutes． At first glance， human-carrying drones sound no more realistic than flying cars． Until recently inventors had never been able to marry automobiles and aircraft in a practical way． Yet a few companies have kept at it： Woburn， for example， has since 2006 been developing Transition， a "roadable aircraft" that resembles a small airplane that can fold its wings and drive on roads． A personal flying car in every garage has proved to be a tough sell， however， as there are serious safety concerns about asking the average commuter to train for a pilot's license and take to the skies． Passenger drones， by contrast， would operate autonomously and leave the "roadable" part behind in favor of larger versions of aircraft that already exist． Passenger drone designs favor "distributed electric propulsion（推进），" meaning instead of one large rotor powered by a large engine they have multiple propellers each powered by its own， smaller motor． This sacrifices lifting power and flight performance in exchange for mechanical simplicity and lighter weight-factors that could make them cheaper to operate． Quieter electric power would make the noise tolerable to city residents， although it remains to be seen how much weight such a vehicle could lift， and for how long． With any of these vehicles， safety is the biggest concern and extends to both the aircraft and the automated systems flying them． Advanced artificial intelligence is needed to fly large numbers of autonomous aircraft without crashing them into one another or， say， the local news channel's traffic helicopter． Carrying people from points A to B seems simple enough， but even the best AI struggles with surprises： What， for example， would a drone do if a landing area suddenly became unavailable？ asks Sanjiv Singh， a Carnegie Mellon University robotics researcher． Instead of leaping to fully automated passenger drones， he suggests first testing the necessary AI in unmanned cargo（货物）runs， and adopting a "mixed mode" approach in early passenger services where pilots are assisted by AI co-pilots． Technical challenges aside， start-ups promoting the technology will have to find a way to convince the public to give their drones a whirl， something that requires a much bigger leap of faith than getting into the backseat of a self-driving car． Passenger drone makers are "obviously still in the incubation（孵化） stages of technology development and improving the basics，" says Mike Hirschberg， executive director of the American Helicopter Society International． "But 20 or 30 years from now life may be a little like The Jetsons where you take advantage of the third dimension and have much more mobility， especially in urban close quarters where ground transportation is gridlocked．" The passenger drone progress may follow a sloping takeoff rather than vertical leap． Carnegie Mellon's Singh sees a long road ahead filled with lots of testing， analysis， regulation and efforts to win the public's trust before the technology becomes a viable transportation option． "There is the danger of someone moving too fast and then having a problem that sets the industry back for some time，" he says．（1）Personal flying cars have failed to gain popularity among households mainly because ____ ．A．people don't have the courage to take the cars to the air．B．people are unwilling to train for a pilot's license．C．people worry that they may not be qualified to fly the cars safely．D．it is practically impossible to combine cars and aircraft together．（2）Which of the following is NOT an advantage of passenger drones？ ____ A． It can lift more weight．B． It is lighter in weight．C． It makes less noise．D． It is simpler in mechanical design．（3）What is Hirschberg's attitude towards passenger drones？ ____ A． disapprovingB． neutralC． skepticalD． cautiously optimistic（4）We can learn from the passage that ____ ．A．artificial intelligence can easily tackle the problems occurring in air traffic．B．human pilots in autonomous aircraft will endanger the safety of passengers．C．the passenger drone industry will make major breakthroughs in the near future．D．the public's distrust may hinder the development of passenger drones．

Dragonflies （蜻蜓） eat a lot， and they constantly hunt for food． What's more， they usually catch it in the air． Zig! The dragonfly catches a small fly． Zag! It seizes a mosquito． Very few insects can outfly the dragonfly． No matter how fast they go， no matter which way they turn， the dragonfly is usually able to follow． Two engineers at the University of Tennessee Space Institute have been studying the way that dragonflies fly． Dr． James Wu and Dr． Ahmad Vakili are studying ways to design a fighter plane that can change direction as quickly and easily as dragonflies can． Why is that important？ If you are in a fighter plane， and another plane is after you， you want to be able to fly more quickly than the other plane， Dr． Vakili says． A dragonfly's wings are the key to its flying ability， Dr． Wu and Dr． Vakili say． If you look closely， you will see that a dragonfly has two wings on each side of its body-a long front wing and a slightly shorter back wing． During flight， small but powerful winds of air move along each of the dragonfly's front wings． Thus， the pressure of air keeps the dragonfly up in the air． A dragonfly's back wings help keep the winds from breaking up． Dr． Wu and Dr． vakili are studying ways to make fighter plane wings use air flow as efficiently as dragonfly wings． Does this mean that someday we'll have fighter planes that look like dragonflies？ Dr． Wu and Dr． vakili say no， because that would not be practical． They don't want wings that look like a dragonfly's． Rather， they want wings that work like a dragonfly's-designed to help fighter planes change course quickly and outfly their enemies．（1）The opening paragraph is mainly intended to show ____ ．A． the flying abilities of dragonfliesB． how dragonflies search for foodC． the food dragonflies preferD． why dragonflies fly so fast（2）What helps dragonflies fly quickly and change direction easily？ ____ A． The shape of their wings．B． The number of their wings．C． The strength of their wings．D． The structure of their wings．（3）Dr． Wu and Dr． vakili want to make fighter planes that can take advantage of ____ ．A． the power of the windB． the direction of the windC． air flowD． air pressure（4）We can infer that the fighter planes designed by Dr． Wu and Dr． vakili may ____ ．A． fly at a greater heightB． look like dragonfliesC． have more functionsD． make a turn quickly

Working for peanuts?Would you work for peanuts? To say yes to this question is not as crazy as you may think. Many college students work very hard for little money—not because they're stupid, but because they want to gain experience and build contacts in their business field. These jobs are called internships.An internship provides college students with a great way to get experience in their majors. Make sure you choose an internship which matches your interests though. For example, if you like writing and photography, why not apply for an internship with a news agency?1(单选题)Why do college students work for peanuts?A. Because they want to get work experience.B. Because they don't need the money.C. Because peanuts are very healthy and delicious.

Passage 2In recent years, "city walk" has quietly emerged among young people in China, becoming a new tourism trend. Unlike traditional tourism, city walk does not aim to visit as many attractions as possible in a short time. Instead, it involves wandering freely or following themed routes through the streets and alleys of a city. Participants can taste local snacks, admire distinctive architecture, and learn about the local way of life. They also use cameras or smartphones to capture the city's scenery and people. This form of tourism allows city walkers to gain a deeper understanding of the history and culture of the city.32. What has become a new trend among young people in China recently?33. How do participants of a city walk record what they see?34. Why can city walk help people understand a city better?35. When has city walk started to become popular among young people in China?36. Translate the sentence "This form of tourism allows city walkers to gain a deeper understanding of the history and culture of the city." into Chinese.
