Small drones（無(wú)人機(jī)）can help carry packages to your home. For two years, Google has been working hard in their secret research lab. They have made great progress. Their latest project is called Project Wing. Project Wing is Google’s invention of a drone delivery service. It is half plane and half helicopter（直升機(jī)）and is slightly bigger than a seagull. It can deliver packages to customers’ doors.

The first drone test was made on a farm in Warwick, Australia. It sent sweets and dog treats to a farmer. The drone flew to the farm, hovered（盤(pán)旋）, and released the package with a wire. Delivery is here!

The best thing about drone delivery services is that delivery times will be greatly cut down. You’ll be able to order online in the morning. And by noon, the delivery drone will deliver you package.

Throughout history, there have been a series of inventions that have helped people move things around, said Astro Teller, lead scientist of Google Wing, to CNN. Teller thinks Google drones will be the next big step in the series.

Interestingly, drones are not that young. The USA has been using armed（武裝）drones since 2002. But drones may also get another use. Film companies have asked to use drones to shoot videos from the sky.

Google’s delivery drones won’t be able to fly to customers any time soon. However, Google has proved that drone delivery is possible. And with Amazon announcing their drone delivery service last year, the heat is on to make safe and suitable drones to fly the skies for customers.

2.According to the reading, Project Wing ______.

Do you know what shouzhang is? It is a diary with decorations (裝飾品) like tapes, stickers (貼紙), drawings and other things. It started in Japan. And now it becomes popular in China.

Twin (雙胞胎的) sisters Lin Ting and Mao Yue from Zhejiang become “stars” on the Internet because they make interesting shouzhang. These two 15-year-old girls are from Grade 8, Wenhui Middle School in Hangzhou. They record things about food, travel, pets, school life and other interesting things in their lives in their shouzhang.

The twins started to make their shouzhang about three years ago. “Nothing will be greater than to look back on these beautiful memories when we get old,” Lin said.

They write funny stories about their two pet dogs Dabao and Gege in their shouzhang. When Lin has too much homework to do, she writes about how she feels. “It makes me feel better,” Lin said. They also write about their favourite food and stars. Mao collected pictures of ice cream, coffee and her hero Zhang Yixing, and stuck them in their shouzhang. They always bring their shouzhang with them when travelling.

Both of them love and do well in drawing. They also have a big box of tapes and stickers. So they think it is easy and interesting for them to make their shouzhang beautiful.
