My uncle is working at a car company. His company is now developing (21) new flying car. The car will have solar panels on its roof and wings, and it will charge (22) battery as it moves. During light traffic, you can use roads. (23) in heavy traffic, you can use the flight mode to avoid traffic. It will be able to carry eight passengers. The car will have an autopilot function, so a driver is not (24) . All passengers can relax, read books or play games while travelling.

I was worried (25) the safety because it is driverless, but my uncle said it will be much safer than a traditional car. It will also be more comfortable and greener because it is solar-powered.

If you think suffering teeth-chattering cold is part of the fun when you travel, then the Harbin International Ice and Snow Sculpture Festival is the carnival for you. Set in Heilongjiang Province in northern China, it’s the world’s biggest snow and ice festival and has plenty of spectacular works and activities.

The annual festival officially runs from January 5 to February 5 but some attractions open to visitors before the opening ceremony, including the most popular of them all - the Harbin Ice and Snow World, made with ice blocks pulled from the nearby Songhua River.

This year, the Harbin Ice and Snow World spans over 600,000 square meters and includes more than 100 landmarks. In addition to walking up the huge shining ice castles, other highlights include an exquisite snow Buddha statue made of more than 4,500 square cubic meters of snow, a 3D light show and the 340-meter-long Northern Lights-themed ice slides.
