It's very usual in Shanghai to see people out walking their dogs. But it's not a common sight to see dogs out walking people. These "out walking people" dogs are special: they are guide dogs and their owners are blind.

Trained guide dogs in Europe and America have been used to help blind people for around 100 years, but it is a new thing in China. A guide dog training center was set up in Shanghai in 2007 and there were only about twenty working guide dogs in the city. There was a city law(法律) that pets and animals shouldn't walk in shops or hospitals. That's why many guide dogs and

their owners were not allowed when they went shopping or tried to take a bus. But guide dogs are not really pets. They are working dogs and their job is to help blind people walk.

Shanghai made a law in 2011: Guide dogs and their owners should be allowed to go to the shops or the hospitals. Blind people and their guide dogs are able to go into many shops now. But the law doesn't make a difference. Only by opening people's eyes and changing most people's attitudes(态度) can guide dogs and their owners go anywhere anybody else can go.

    The Flame Mountain(火焰山)is about 200 km away from Urumqi in Xinjiang. It is in a place with many high mountains around it. It is much hotter than nearby places. If you want to enjoy the feeling of a hot shower in summer, it's the right place to go!

    On hot summer days, it can get hotter than 80℃. Try to cook eggs or cakes in the sand and they will be ready in a few minutes!

Does rain help make it cooler? People hardly see rain in 10 out of the 12 months in a year. Why? For most of the time, the raindrops dry in the hot air before they reach the ground.

    The mountain came into being millions of years ago when the earth was changing a lot. We can't see any plants on the top of the mountain, only red rocks. They make the whole mountain look red. In hot air and strong sunshine, the mountain looks like a burning flame. That's where its name comes from.

    When you are at home, you may often help your mum with housework like folding the clothes. But can you imagine folding your phone screen? Huawei's newest phone, the Mate X, is foldable. You can fold it in half as if you are closing a book. But what makes the Mate X different is that it is folded from the outside.

    The Mate X is both a phone and a tablet(平板电脑). When folded, it works as a phone. When opened, it is a tablet. The phone is very thin. When it is open, it is 5. 4mm thick, and when it is closed it is just 1l mm. 5Gcan also work on Mate X, which means users can get a whole movie in just a few seconds.

    But users can only take selfies(自拍) when the phone is folded. That's because the phone doesn't have a front camera(镜头).

    Huawei, the Mate Xmaker, says they are going to sell MateXin August this year, and the price is set at 2299 dollars, which is much higher than people expected. Can you accept the price for changing a phone?
