Is traffic a big problem where you live? Increased cycling may be the answer. Where are the best places to live and cycle? A new report lists the best bike—friendly cities around the world.
Top of the list is Amsterdam, the bike capital of the world. An incredible 40% of all traffic movements are by bicycle. There’s an extensive network of safe, fast and comfortable cycle routes. Copenhagen, the city of bikes, is a city where 32% of workers cycle to work because it’s fast and easy. Berlin is another European city that’s great for cycling. The city has about 80 kilometres of bike lanes, and 50kilometres of pavement paths. Cycling accounts for 12% of total street traffic.
Barcelona has been praised for its cycle service “Bicing”. It’s a bicycle service that allows users to take bicycles from any of the 100 stations spread around the city. Later, they can leave them at any other bike station inside the urban area of the city. The city has created a “green ring” that surrounds the city area with a bike path. There are 3,250 parking spaces for bikes at street level at present. Barcelona City is also building a new underground car park for bicycles.
The UK has its cycle friendly cities too. Bristol is the birthplace of “Sustrans” the cycle-route charity which was formed 30 years ago. One of their projects was turning an old rail line between Bristol and Bath into a bike route. Other bike friendly cities in the UK include Cambridge and York. Cambridge is an old city but has still managed to build good cycle infrastructure (基础设施), and cyclists are considered at every stage of any new developments.
Bicycle is a most popular means of transportation in China. Nowadays, riding a bicycle is also a good way to support low-carbon living. Beijing can be one of the best bike-friendly cities in China. There are many riding routes in Beijing for outdoor-lovers to explore. Cyclists can get close enough to experience the history and culture of Beijing, including the Forbidden City, Drum Tower, the Water Cube etc.
1. What are the bike-friendly cities mentioned in the passage?2. What makes Amsterdam the bike capital of the world?
3. Please decide which part is false in the following statement, then underline it and explain why.

4. As far as you know, what has been done to make Beijing a bike-friendly city?
Amsterdam has become very popular with cyclists because of the convenience for bicycles. In the 1960s, a group of cycling fans came up with an idea

5 . When it comes to lowering our carbon emissions (排放), it seems that nothing is simple. Electric vehicles (EVs) act as an example of potential greenwash. “They seem very attractive at first sight,” writes The Next Web in a report. “When we look more closely, it becomes clear that they have a substantial carbon footprint.”
The rare earth metals and costly minerals included as essential ingredients in EV batteries are not renewable. What’s more, their extraction (提炼) is often anything but green.
So the question is: is it worth it? Just how much emission reduction can EVs justify? Luckily, a life cycle assessment has been done to give us some answers.
“A life cycle analysis of emissions considers three phases,” writes The Next Web. “the manufacturing phase, the use phase, and the recycling phase.” In the manufacturing phase, the battery is to blame. “Emissions from manufacturing EV batteries were estimated to be 3.2 tons of carbon dioxide (CO2), 1/4 of those from an electric car, 13 tons of CO2. Those were bigger than emissions from gas cars, 10.5 tons of CO2.” If the vehicle life is assumed to be 150,000 kilometers, emissions from the manufacturing phase of an electric car are higher than gas cars.”
In the use phase, the source of electricity the consumer is using to power their car comes into play in a major way. “To understand how the emissions of electric car vary with a country’s renewable electricity share, consider Australia and New Zealand,” continues the report. “In 2018, Australia’s share of renewables in electricity was about 21%. In contrast, the number in New Zealand’s was about 84%. Electric car emissions in Australia and New Zealand are estimated at about 170g and 25g of CO2 per km respectively. As a consumer, our car is only as green as our country’s energy mix.”
Finally, in the recycling phase, we look at vehicle dismantling(拆除), vehicle recycling, battery recycling, and material recovery. “The estimated emissions in this phase, based on a study, are about 1.8 tons for a gas car and 2.4 tons for an electric car. This difference is mostly due to the emissions from battery recycling, which is 0.7 tons,” shows in the report. “While electric cars cause more greenhouse gas emissions than gas cars do, it's important to note the recycled batteries can be used in subsequent batteries. This could have significant emissions reduction benefits in the future. For complete life cycle emissions, the study shows that EV emissions are 18% lower than gas cars.”
So here’s the takeaway: EVs are greener. Maybe they’re not as green as we thought. There’s certainly room for improvement. But the real challenge lies in speeding the global energy transition toward greener energy-production.

| D．To examine the energy sources of gas cars and EVs. |
| A．By giving instructions. | B．By highlighting features. |
| C．By making comparisons. | D．By analyzing cause and effect. |
| A．Recycling of batteries. | B．Overall driving distance. |
| C．Manufacturing technology. | D．Government’s energy policy. |
| A．EVs are worthy of the praise they have received. |
| B．EVs are not successful for their environmental downsides. |
| C．EVs will no longer be widely accepted for their emissions. |
| D．EVs are not truly green until their energy sources become green. |

9 . I was desperately nervous about becoming car-free. But eight months ago our car was hit by a passing vehicle and it was destroyed. No problem, I thought: we’ll buy another. But the insurance payout didn’t even begin to cover the costs of buying a new car—I worked out that, with the loan (贷款) we’d need plus petrol, insurance, parking permits and tax, we would make a payment as much as £600 a month.
And that’s when I had my fancy idea. Why not just give up having a car at all？I live in London. We have a railway station behind our house, a tube station 10 minutes’ walk away, and a bus stop at the end of the street. A new car club had just opened in our area, and one of its shiny little red Peugeots was parked nearby. If any family in Britain could live without a car, I reasoned, then surely we were that family.
But my new car-free idea, sadly, wasn’t shared by my family. My teenage daughters were horrified. What would their friends think about our family being “too poor to afford a car”？(I wasn’t that bothered what they thought, and I suggested the girls should take the same approach.)
My friends, too, were astonished at our plan. What would happen if someone got seriously ill overnight and needed to go to hospital？(an ambulance) How would the children get to and from their many events？(buses and trains) People smiled as though this was another of my mad ideas, before saying they were sure I’d soon realize that a car was a necessity.
Eight months on, I wonder whether we’ll ever own a car again. The idea that you “have to” own a car, especially if you live in a city, is all in the mind. I live—and many other citizens do too—in a place that has never been better served by public transport, and yet car ownership has never been higher. We worry about rising car costs, but we’d be better off asking something much more basic: do I really need a car？Certainly the answer is no, and I’m a lot richer because I dared to ask the question.
