Many people may not know the name of the girl in the photo but her large and clear eyes can often be seen in newspapers.

    Her name is Su Mingjuan and now she's more than 30 years old. In 1991, when Su was only 8 years old, Xie Hailong, a photographer from China Youth Daily, took a picture of her in a classroom which was in a poor condition in Anhui.

    The photo was later used as a poster for Project Hope. It has become a symbol of the country's efforts to make more people realize the importance of education. Her large and clear eyes crying for knowledge in the picture have moved a big number of people across China, who have donated (捐赠） money to help children continue their schooling since then.

    Having received help from Project Hope, Su herself has also been helping poor students. She began to study at Anhui University in 2003. After entering college, she wrote to the China Youth Development Foundation, the organizer of Project Hope, to transfer her living allowance (补助) of 900 yuan a term to other students in need. And she began to do part-time jobs to make money. After graduation, Su found a job in a bank. Since she started working, she has donated 1,000 yuan every year.

    Since it was started in 1989, Project Hope has received about 13 billion yuan in donations from home and abroad. And the money has been used to build over 19,000 primary schools and help over 5. 5 million children.

Nowadays, "toilet revolution" is a thing in China.China isinvesting seven billion yuan in the project.The money is spent building or upgrading(改进) toilets in 30,000villages.

Experts have agreed that a "toilet revolution" is very important.Bettertoilets mean healthier lives and better living standards.Better toilets can alsohelp encourage tourism and improve the economy.

"Toilet revolution" was started in 2015.Chinese president Xi Jinpingthen called for improvement to toilets across China.The government has investedmore than 1.6 billion yuan in the project since then.Nearly 70,000 toilets havebeen built or upgraded.By the end of 2017, 45 percent of rural residents (居民) had been usingstandard toilets.In 2013, that number was only 36 percent.

In cities popular with tourists, more expensive toilets have been built.Thesetoilets have ATMs, Wi­Fi and recharging (充电) stations for mobile phones.Some toilets, meanwhile, havebeen expanded (扩大). Now, they have special cubicles (隔间) for the disabled and adults with young children.

China, in fact, is not alone in focusing on toilets.According to Bill Gates'foundation, forty percent of the world's population doesn't have flush toilets.UNICEF(联合国儿童基金会) says atleast 1.2 million young children die of diarrhea each year.Contact with human wasteis the main cause.Gates says toilets of the future will be able to save 800 livesevery day.

Lake Tahoe is the best place to go during winter vacations. You will have a lot of fun if you follow these tips(提示).

The first thing you should do is to wear at least(层) three layers(层) clothes. If you don't, you will have a cold!

First, don't drive on the highway when it's snowing, or a traffic jam(交通堵塞) will make you angry. Second, don't try the sk i resort(度假村) food. Believe me , it's terrible. Bring your own food. At last, be careful when you sk i by yourself. Skiing is a dangerous sport. When you are skiing, you may fall down, get hurt or even die.

Since August，driverless taxis can run on roads in cities including Wuhan，Chongqing（科技） into reality，sad China Daily.

Why do we develop self—driving cars？

Self—driving cars give us many benefits（好处）.They use computers to sense（感知） the things around them and make better use of space.This means fewer traffic jams and better parking of cars.For disabled（残疾的），self—driving cars can also help them get around more easily.By using computers，they can avoid unskilled，careless or drunk driving and so on.This can cut down 90 percent of road accidents，said the website TechDim.

Is self—driving cars totally safe on roads？

Self—driving cars can't react（反应） as fast as a human driver could if something unexpected（意料之外的） happens.Also，it is difficult for self—driving cars to see clearly.The car's computer could also get hacked（非法入侵），making it crash（碰撞），technology companies are working on these problems.

 If you are looking for a simple place to stay for a few nights, a capsule(胶囊) hotel might be a good choice. Providing small rooms and just a few basic services, these hotels can help people save lots of money.

 What do the rooms in capsule hotels look like? The rooms are usually the size of a bed. They are very small, but they have enough space for you to sit up on the bed. Rooms in capsule hotels are usually side by side and on top of one another. So, if you are staying on the top level, you have to use a ladder to climb into your room. There are also curtains( 帘布) for you when you' re sleeping. Although there's little you can do inside your room apart from ( 除了……还 ) sleeping, capsule hotels usually provide other services. Shared bathrooms and dining areas are available (可提供的) for you to use.

 The first capsule hotel appeared in Osaka, Japan in 1979. Many Japanese loved the idea, so more capsule hotels opened all over the country. From there, capsule hotels spread to several other countries such as India and Iceland. China has also seen a rise in the number of such hotels in recent years. And they are quite popular with young people.

 Many experts(专家) believe capsule hotels will become more popular as time goes by. What do you think?
