4 . It would be much more convenient if electric cars could be recharged wirelessly. Some electric toothbrushes and other small devices, such as mobile phones, can already be topped up in this way using a process called electromagnetic induction (电磁感应). This employs some kind of electrical current flowing through a coil (线圈) to create a varying magnetic field, which then generates another current in a second coil placed alongside it, which is used to recharge a battery.

As users of electric toothbrushes and phones will know, device and charger must be both close to each other and precisely adjusted for this process to work. That is tricky to achieve with an electric car, which sits above the ground and requires higher levels of energy transfer.

These problems are being overcome with advances like that made by WiTricity, a firm based near Boston. This company was founded in 2007 to commercialize the work of Marin Soljaèi and his colleagues at the Massachusetts Institute of Technology. Dr Soljaëi knew, in theory, that by having the transmitting and receiving coils resonate (共振) at the same frequency it should be possible to transfer greater amounts of energy over longer distances. In practice, he sought to commercialize the system to large companies, such as BMW.

An advantage of wireless recharging is what WiTricity’s boss calls “power snacking”. This is topping up the battery when a car is stationary for a short time. The company provides systems to recharge taxis in this way while they wait in line, and to do the same for electric buses at bus stops. It is also possible to charge vehicles while they are on the move. That might make sense in places where vehicles often queue up, such as at airports.

1. How can electric devices be charged wirelessly?

A．By devices close to chargers.

B．By high levels of energy transfer.

C．By an electrical current flowing through a coil.

D．By a process of electrical currents transformation.

2. What makes it possible for electric cars to get lots of energy wirelessly?

A．Commercializing the system to BMW.

B．Charging vehicles while they are on the move.

C．The transformation of energy over longer distances.

D．The good cooperation between the transmitting and receiving coils.

3. What does the underlined word “stationary” in paragraph 4 probably mean?

A．Moving.

B．Motionless.

C．Firm.

D．Unchanging.

4. Which might be the most suitable title for the text?

A．Various forms of wireless-charging systems.

B．Advantages and disadvantages of wireless-charging.

C．How to charge a car with a wireless-charging system.

D．Wireless vehicle-charging is starting to look promising.

6 . When Chris Visions began painting a ground painting in Richmond, he had no idea his street art might help save lives.

Since the painted crosswalk was finished in September, the crossroads has become safer for walkers and motorists. The overall changes were fairly small but still significant in the community, and part of a larger study in various cities that showed far fewer crashes at the art crossroads compared with the prior year.

While the initial purpose of the painting was to celebrate the 150th anniversary of Jackson Ward, it came with an unexpected benefit: The painting has encouraged walkers and motorists to “slow down and take safety into consideration,” said Visions, 37, a local comic book artist.

The painting, which was created with a group of art students from a local arts nonprofit, is one of three new crosswalk art projects in Richmond. The nonprofit base funded 42 street paintings in 41 cities across the country since 2019, with funds of up to $25,000.

As part of the project, Bloomberg Philanthropies collaborated with Sam Schwartz Engineering, a consulting firm, to explore what effect the street art was having on safety. The results of the study showed a drop in the number of traffic accidents in areas with art.

The study examined the crash history at 17 art sites across the country that have a minimum of two years of crash data. It found 83 fewer crashes at the analyzed crossroads — more than a 50 percent decrease compared with data from before the crosswalks were painted.

“Crosswalk art can improve behavior behind the wheel and it can protect the weakest people on the road,” said Janette Sadik-Khan, a principal for Bloomberg Associates and the former officer of the New York City Department of Transportation.

10 . 阅读下面材料，在空白处填入适当的内容（1个单词）或括号内单词的正确形式。

The China-Laos Railway,     1     connects Kunming in southwest China’s Yunnan Province with the Laotian capital, Vientiane,     2     (start) operation on Dec 3. 2021. The 1035-kilometer-long railway is a landmark project and an important part of the Pan-Asian railway network. It will not only benefit the two peoples, but also     3     (significant) improve regional connectivity.

    4     (locate) southwest of China, Laos is the only landlocked country in Southeast Asia and mainly depends on road, water and air transport for the movement of people and goods. It has long been a dream for the Lao people to see their country change from a land-locked country     5     a “land-linked one”, and the opening of the new railway is a big step toward turning     6     (they) dream into reality.

The new railway will improve Laos’ transportation and promote its tourism as well as agricultural processing industries. It will also enable Lao businesses to     7     (well) fit into regional and global supply chains.

China and Laos have stood together through thick and thin and engaged in mutually beneficial cooperation on the basis of equality. Besides, China and Laos were the first     8     (sign) an agreement based on the Belt and Road Initiative. The opening of the China-Laos Railway will thus help speed the     9     (develop) of the China-Laos Economic Corridor, and will further advance the building of a China-Laos community with     10     shared future.
