Driverless taxis are now available for hire in suburban Beijing, marking a new chapter in intelligent transport.

This is the first time that a 【小题1】(full)autonomous group of vehicles has got 【小题2】(permit)to operate in a world-class city.

Previously, robotaxis 【小题3】(require)to have a human driver in case of an emergency. However, the two companies will be allowed 【小题4】(operate)robotaxis with just the passengers inside.

The two companies, both among the leading players in China’s autonomous driving industry, have each put 10 autonomous vehicles in 【小题5】 60- square- kilometer area in Yizhuang, located in the southern suburb of Beijing.

Baidu plans to expand 【小题6】(it)autonomous ride-hailing services to 65 cities in 2025 and 100 in 2030.

The market size for China’s self-driving taxi service is expected to reach 1.3 trillion(188.6 billion U.S. dollars)by 2030, 【小题7】(account)for 60 percent of the country’s ride- hailing market at that time, according to 【小题8】(science)forecasts from a global company, IHS Markit.

The bag 【小题4】(it) weighs just 160 grams, 【小题5】 the rechargeable battery pack powering it weighs an extra 120 grams.

The true innovation behind the Willcook microwave bag is the stretchable fabric that generates heat just by drawing power from a battery pack. The revolutionary fabric has the same 【小题6】 (flexible) and lightness as regular cloth, yet 【小题7】(provide) quick and uniform heating. 

The inside of a Willcook microwave bag reaches 80°C in 5 minutes after 【小题8】(power) on, but users can set the temperature between 40°C and 250°C via a smartphone app 【小题9】(call) Hotopia. The included battery pack lasts for 8 hours on a full charge and has 【小题10】 small, dedicated pocket on the side of the bag.

Don't hang the silk products onto the sharp or metal hook to avoid 【小题10】 (intention) damage.

Chinese silk has become more and more popular throughout the world. It is one of the symbols that can represent China.
