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.

7 . 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.

9 . 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.

10 . Getting around Venice by travelling along its water ways is a delight for all visitors. Apart from offering unforgettable views of the architecture, the city's transportations are convenient, efficient, and also relatively inexpensive.

PASSES

Instead of paying EUR 7 per ride, a better option is to purchase one of ACTV's passes, which offer unlimited travel for 1 day (EUR 20), 2 days (EUR 30), 3 days (EUR 40) or 1 week (EUR 60). For children and young people between the ages of 6 and 29, ACTV offers a special "Rolling Venice" 3-day pass (EUR 29).

BY GONDOLA

Considered by many as the most symbolic feature of Venice, today gondolas circulate most often on canals in the centre of the city, carrying tourists on rides at fixed rates, which tend to be rather high. A 40-minute ride costs around EUR 100, but may be shared by as many as six passengers.

BY RENTAL BOAT

It is possible to rent a boat to travel around Venice's canals. A boating permit is not required, but you will need to pass a basic turning and docking test before being allowed to rent a boat. Rates start at EUR 30 per hour.

BY WATER TAXI

Getting around by water taxi in Venice is most costly, but can be a convenient option when you are in a hurry or need to carry a lot of luggage. The initial charge is EUR 15, then EUR 2 per minute. If you have more than one bag per passenger, there is a charge of EUR 3 for each additional piece.

Note: There are only four fueling stations for boats in Venice. Make sure you note their locations before heading out.

1. What is said about the ACTV's pass?

A．It provides the tourists with five choices.	B．It is only suitable for kids and the young.
C．It should be ordered ahead of time online.	D．It is a certificate given to the foreign tourists.

2. Why does the author recommend gondola?

A．Because it is the most economical means.	B．Because tourists can enjoy the city for longer.
C．Because tourists will be clear about the cost.	D．Because it represents the city of Venice.

3. Which of the following may cost you most?

A．PASSES.	B．BY GONDOLA.
C．BY WATER TAXI.	D．BY RENTAL BOAT.
