1 . More cities, states and regions are committing to comprehensive climate plans to decarbonize (减少碳排放) transportation by 2040. The need for action is now, and we need to rise to the challenge quickly. Google technology is unlocking our ability to generate climate-related insights and impact on the globe.

The transportation sector is where global greenhouse gas (GHG) emissions are rising the quickest. In 2018, Google launched the Environmental Insights Explorer (EIE). Using AI, the systems analyze transportation trends in a city by mode， helping local governments assess their progress in tackling GHG emissions. GHG inventory processes (温室气体排放清单) traditionally take months and multiple data sources to collect, and are now highly efficient, allowing government staff to reduce the cost and personnel burden of reporting.

In pursuit of helping more cities take action against climate change, we will make transportation insights available in EIE for over 20,000 cities and regional governments by the end of the year, making it one of the largest ever collections of high-quality, globally consistent environmental data sources.

With EIE, cities have free access to Google’s unique mapping data and insights so they can decide on cleaner transport policies. As part of Google’s most ambitious decade of climate action, we’ve committed to helping more than 500 cities and local governments reduce a total sum of 1 billion tons of carbon emissions per year by 2030 and beyond.

As the window continues to narrow on carrying out policies and plans to reduce emissions, we’re collaborating with other associations, committed to addressing climate change. Our work with Cities. Climate Leadership Group(C 40) will help us better support the needs of cities. Together we can provide higher-quality transportation activity data to measure and track GHG emissions at a global scale, while also giving state and local governments resources to better understand what’s working at a local level.

4 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

The Silk Road was a network of trade routes     1    (connect) the East and the West in ancient and Medieval times. In addition to silk, varieties of other goods     2    (trade) along the Silk Road, and the network was also important for migrants and travellers, and for the spread of religion, philosophy, science, technology, and     3     (art) ideals. The Silk Road had a significant impact on the lands     4    which the routes passed, and the trade played a significant role in the development of towns and cities along the Silk Road routes.

Many merchants along the Silk Road were involved in relay trade,     5    an item would change owners many times and travel a little bit with each one of them     6    reaching its final buyer. It seems to have been     7    (high) unusual for any individual merchant to travel all the way between China and Europe or Northern Africa. Instead, various merchants specialized in transporting goods through various sections of the Silk Road.

The Silk Road established     8    (early) connection between the East and the West. It was of great significance in the promotion of world     9    (civil) and the progress of human society. Research and development of the Silk Road today continue to have     10    incredible impact.

7 . The PAL-V Liberty is a revolutionary vehicle that can travel on both land and air. It is the world’s first commercial flying car, and it is now available for pre-order. The PAL-V Liberty is developed by a Dutch company called PAL-V International B. V., which stands for Personal Air and Land Vehicle. The company has been working on the project since 2001, and has successfully tested the prototype in 2012.

The PAL-V Liberty is a two-seater hybrid car and gyroplane, which means it has a three-wheeled chassis and a foldable rotor on top. It can switch between driving mode and flying mode in about 10 minutes, with the help of a semi-automatic system. It has a top speed of 160 km/h on the road and 180 km/h in the air, and can fly up to 500 km on a single tank of fuel. It uses regular gasoline, and can be refueled at any gas station.

The PAL-V Liberty is expected to be delivered to customers in 2023, alter obtaining the necessary certifications from aviation authorities. The company claims that the vehicle meets the existing regulations of both cars and aircrafts, and that it is safe and easy to operate. However, the PAL-V Liberty is not a cheap vehicle, nor is it accessible to everyone. It costs599,000 euros (about 4.7 million yuan) for the Pioneer Edition, which includes flight training courses, power heating and personalization options. There is also a cheaper Sport Edition, which costs 299,000 euros (about 2.3 million yuan), but it has less features and requires the buy er to pay an additional 10,000 euros(about 78,000 yuan) for flight training.

To drive the PAL-V Liberty, one needs both a driving license and a pilot license. The vehicle also requires a runway or airstrip to take off and land, as it cannot do so vertically like a helicopter. The company says it has received 70 orders for the vehicle so far, mostly from customers in Europe and North America. The PAL-V Liberty is a groundbreaking innovation that could change the future of transportation, but it also faces many challenges and limitations.

1. What’s the limitation of the Pioneer Edition of the PAL-V Liberty?

A．Lack of customized selection.	B．Failure to land and take off vertically
C．Extra money to be paid for flight training.	D．Disagreement with the existing traffic rules.

2. What can we infer about from the passage?

A．The PAL-V Liberty has been used in our daily life.

B．If you have a pilot license, you can drive the PAL-V Liberty.

C．It can switch between driving and flying mode in a short time

D．The Sport Edition is more attractive features than the Pioneer Edition.

3. What's the author’s attitude towards the PAL-V Liberty?

A．favorable

B．skeptical

C．objective

D．indifference

4. What is the best title for the article?

8 . Researchers have proposed a novel method for counting and tracking vehicles on public roads, a development that could improve current traffic systems and help travelers get to their destinations faster.

Using the cameras already installed on campus buses at the Ohio State University, researchers proved that they could automatically and accurately measure counts of vehicles on urban roadways, detect objects in the road and distinguish parked vehicles from those that are moving.

In previous studies, Ohio State researchers found that using these mobile cameras provides much better spatial and temporal (时间的) coverage than relying on often temporarily placed sensors that don’t provide a view of many streets and roads in a city.

“If we collect and process more high-resolution (高清) spatial information about what’s happening on the roads, then planners could better understand changes in demand, effectively improving efficiency in the broader transportation system,” said Keith Redmill, lead author of the study.

“If we can measure traffic in a way that is as good or better than what is conventionally done with fixed sensors, then we will have created something incredibly useful extremely cheaply,” he said. “Our goal is to start building a system that could do this without much manual intervention because if you want to collect this information over lots of potential vehicles and lots of time, it’s worth fully automating that process.”

While still a long way from total implementation (实施), the study suggests the system’s results bear promise for the future of intelligent traffic surveillance. Transportation planners, engineers and operators make vital decisions about the future of our roadways, so when designing transportation systems to work over the next 30 to 50 years, it’s necessary that we give them data that allows them to improve the efficiency of the system and the level of service provided to travelers.
