21、Plugs across America
The United States has around 150,000 fuel stations to re till fossil-fuel-burning vehicles. Despite the rapid growth of all-electric vehicle in America — 400,000 of them were sold in 2021, up from barely la, 000 in 2012 — the country has only 6,000 fast electric charging stations, the kind that can rapidly charge a battery-powered car.
A glance at America’s charging map reveals a lot of charging deserts. This makes sense, as EVs (electric vehicle) still represent less than 3% of new car sales. Large cities have a growing number of fast charges, but not nearly enough to accommodate so many EVs. Away from cities, these charters are along interstate highways closely enough to allow electric cars safe passage. Otherwise, they are nearly nonexistent in rural America. And EV stations have a problem that gas stations don’t: “Even the fastest Tesla supercharger is still going to take 15 minutes to put a couple hundred miles on the vehicle,” says Jeremy Michalek, a professor at Carnegie Mellon University.
Michalek says American charging facilities fall far behind what’ needed for the whole country to transition to electric driving. On the bright side, there is time to catch up, because not all Americans will embrace at once. Most early adopters were those with access to a charge at home in their garage or parking space. Those owners can wake up with a full battery and only need to rely on public charters when they leave town on an extended trip. But as the country gets to higher levels of EV adoption, the current facilities won’t be enough. That is why Michalek says the US needs to prioritize increasing the number of charges at rest stops along well-traveled highways, especially as more people use electric cars for summer-time road trips.
“As we act to higher levels of EV adoption, if we don’t have enough chargers for peak demand, the wait times are going to be unlike what we see with gas stations,” he says.
Charging dead bones will be larger as more Americans consider an EV. Renters who do not have the option to install a home charges will be hesitant to go fully electric until they can feel confident a public plug will be there when they need it. And as more households drive only electric vehicles, it will be crucial that people can get to all the places they want to go.
In the best case, Michalek envisions public-private cooperation to build a national charging network. The US government has promised to install plugs throughout rural areas, while companies constructing charging stations across America will have a strong motivation to fill in the country’s biggest cities. After all, companies like Electrify America, EV go, and Charge Point charge customers of energy they use.
【1】It can be learned from the 2nd paragraph that ______.
A．there is a shortage of charging stations in the rural areas of America
B．it takes about 15 minutes for an average charge to charge a battery-powered car
C．more electric vehicles are sold than fossil-fuel burning cars in large cities in America
D．there are enough charges in America considering the limited sales of new electric vehicles
【2】Which of the following statements would Michalek most probably agree with ?
A．Companies setting up charging stations are hesitant to go electric.
B．Those who already have a home charge don’t have to find a public plug.
C．Top priority needs to be given to adding more charging stations across the country.
D．There is enough time to establish a charging network, because not many EVs are uscd.
【3】What can be inferred about the renters ?
A．Some renters don’t have the intention to go electric.
B．Some renters might not be authorized to install a home charge.
C．As more renters are unwilling to use public plugs, the charging dead bones are growing.
D．Some renters might not have enough confidence in the public plugs for the safety reasons.
【4】Who does Michalek expect to work together to establish the charging network nationwide?
A．The government and some companies.
B．The local government and every household.
C．The charging facility providers and every family.
D．The federal government and the local rural government.
22、Siri is an artificial intelligence (AI) that you can carry around in the pocket, where it waits patiently to be told what to do. In the week we spent together, my AI assistant has performed admirably in finding me restaurants, or the location of the nearest coffee shop.
A typical command might be: “Reserve a table for two at a good French restaurant in San Francisco.” Siri responds by presenting a list of top-rated restaurants that can be booked on OpenTable.com. If you say which time you want, it can book you a table without your lifting a finger. In some ways Siri is just a fancy front-end (前端程序) to the 35 sites it can connect to, from taxi booking sites to movie review databases. But what’s new is the way it can analyze the intentions of its master or mistress and use those sites to put them into action.
Siri attaches probabilities to the explanation of each word and cross-references (对照检索) with your location and other data, some of which you must provide yourself. To send email reminders, Siri obviously needs to know your email address. To “find me the flower shop closest to work”, it needs to know where you work. To pay bills or buy airline tickets, it would need access to your credit card.
That raises the question of how far we are willing to trust a piece of software that can go and do things for us based on what it “thinks” we mean, a topic that occupies some engineers working on artificial intelligence. The more data, and power, you give your virtual assistant, the more damage it could do. Siri may be simple, and always shows its explanation of a command before carrying it out. But it gives users a preview of a new balance between privacy, trust and convenience that the expansion of AI into everyday life is likely to develop.
【1】What is Siri?
A. A digital e-book reader.
B. A music-sharing software.
C. A voice-controlled website.
D. An artificial intelligence software.
【2】When asked “do I need my umbrella today?”, what will Siri probably respond with?
A. The list of umbrella makers.
B. The list of umbrella shops.
C. The local weather forecast.
D. The local climate conditions.
【3】Siri is new in that it has the ability ______.
A. to understand what you speak
B. to connect a lot of websites
C. to give a variety of commands
D. to create computerized database
【4】What question does Paragraph 4 answer?
A. Does Siri think itself? B. Can I trust you, Siri?
C. Is Siri simple for use? D. Will Siri be popular?
23、In a lot of other states in America, warm sunny days mean lazy afternoons are spent on the beach. In Oregon, people pack hiking shoes with their bathing suits. Here are 3 incredible hikes for you.
Cascade Head Preserve
Distance: 6.8 miles
Difficulty: Moderate
Nearest Town: Lincoln City
Managed by the international nonprofit The Nature Conservancy, the Cascade Head Preserve is an excellent hike that typically marks the division between the north and central Oregon coast. There are upper and lower trailheads (小道的起点), with about 3.4 miles of trails between the two.
Cape Lookout
Distance: 5 miles
Difficulty: Easy
Nearest Town: Tillamook
Of all the capes on the Oregon coast, Cape Lookout might be the most famous, projecting 1.5 miles into the ocean. Visitors can tackle the five-mile, round-trip hike to the tip of the cape where they can enjoy several incredible views over the Pacific Ocean. Separate trails lead down to South Beach and the Campground.
Clatsop Loop Hike
Distance: 3 miles
Difficulty: Easy
Nearest Town: Cannon Beach
There are several trails that traverse (横越) Tillamook Head at Ecola State Park, but the Clatsop Loop Hike is known for its breathtaking Cliffside views and quiet forested paths. Take the seaside trail from Indian Beach to the Hikers Camp, then take the forested path back.
【1】Which is the dividing line between the north and central Oregon coast?
A．Tillamook.
B．Cascade Head Preserve.
C．Cape Lookout.
D．Cannon Beach.
【2】What can you do while standing on the tip of the cape?

D．The quiet seaside.
24、In the United States, people often use large amounts of salt to remove dangerous ice from roads and walkways in the winter. But when the spring arrives, all that salt can really damage plants in the garden. Salt is the chemical sodium chloride.
Salt pulls water from living cells, like plant roots and the healthy ground soil around them. So, spring growth may show up lighter in color than normal, or, in the worst cases, plants may simply die. Rain can wash away much of the salt, permitting some older plants to live. Salt can also be removed by pouring a large amount of water on the ground where plants are growing. But the best action is to simply use less salt.
There are, of course, other things that can be used to cover for sodium chloride. One is the chemical calcium chloride, which does less damage to plants and melts ice faster than salt. It also works when the temperature is below negative 17 degrees Celsius. Salt loses some of its effectiveness at temperatures below negative 12 degrees.
Still, calcium chloride does put chloride ion (氯离子), which plants don’t like, into the soil. It is also more expensive and can do more damage to cars. Calcium magnesium acetate, also called CMA, has become a popular alternative. It is made by combining limestone, a type of rock, and vinegar. It breaks down naturally so it does not damage plants or soil. It stays on roads and does not hurt cars.
CMA does have problems, however. It is most effective at around negative 9 Celsius, just like salt. And it is better at stopping ice from forming rather than removing it. So, it is best placed on a road before the temperature gets very cold. Some materials other than salt—such as sand or very small pieces of wood—can also work against ice. But they can be very messy.
【1】What is the poor result by using salt to remove ice?
A．All the plants are likely to disappear overnight.
B．The plants may well look much weaker than ever.
C．Some older plants can’t resist being washed away.
D．A large amount of water is trapped on the roads.
【2】What does the underlined part mean in the 3rd paragraph?
A．Remove.
B．Wrap.
C．Collect.
D．Replace.
【3】What is the advantage of calcium chloride?
A．It functions well at cold temperatures.
B．It provides chloride ion to the soil.
C．It can melt ice just above minus 17℃.
D．It brings no damage to plants or soil.
【4】The author wants to show
A．many materials can be used to remove ice.
B．using less salt is beneficial to your plants.
C．sand and pieces of wood are eco-friendly.
D．too much salt is used on the roads in the USA.
