Keep away from a fire. You could fall down and burn yourself on the fire.
   If you are driving when an earthquake happens, stop the car if it's safe. Stay inside your car until the earthquake stops, and don't drive near bridges. Try not to stop by power lines or trees. These could fall and hurt you.

    American Sign Language, often called ASL, is used by most people with hearing problems in the United States and Canada.

    Besides ASL, there are more than fifty sign languages used throughout the world today, including Mayan Sign, British Sign, Israeli Sign, and Chinese Sign. Like spoken languages, sign languages are different from each other. But all sign languages are based on sight instead of sounds.

    Sign languages have several main visual (视觉) parts that work together to express meaning. The first part is the shape made by the hands. Movement is also important. Moving the body or organs (器官) like hands affects the meaning of the shape. The place where the sign is made and the direction the hands face are crucial as well. Other visual clues (线索), such as the expression on a person's face, can sometimes change a sign's meaning. For example, a change in a smile can show whether a signer is happy, very happy, or overjoyed. Raising the eyebrows can mark a question.

    In sign languages, the visual parts are combined (结合) in different ways to create signs.

These signs stand for things, actions, feelings, and ideas. ASL has about 4,000 different signs. Like spoken  languages,  sign  languages  cannot  be  translated  word-for-word.  

    For English word may be represented by a series of signs in ASL. Or several English words may be

represented by a single ASL sign. Unlike spoken languages, the signs are organized according to sign-language grammar and the most important word or idea is signed first.

    In ASL, the letter signs are made with one hand. Signers would rarely, if ever, spell out all the words they are signing. That would be as awkward and slow as speakers spelling each spoken word. However, American Sign Language does not have signs for proper names, so signers may use the alphabet to spell these. Also, sign languages often borrow words from other languages. They may spell words using finger spelling which is done with a set of hand shapes that stand for letters of the alphabet.

    Sign languages  develop  naturally  when  people  with  shared  culture  and  needs  want  to communicate with each other. Signers are closely linked to each other, perhaps more than to speaking people in their own communities. Signers share points of view, values, needs, and problems,as well as languages.

Most people have heard of the Great Wall of China, but not many people outside of China know about the Grand Canal.

This man-made waterway — known in China as Da Yunhe — is more than 1,700 kilometres long and some parts of it are more than 2,000 years old. It connects the north of China with Hangzhou, a city in the southern part of the country. It's the longest man-made waterway in the world.

It was built as a way to transport grain(谷物) from the rich agricultural land in China's south to cities in the north. In fact, it's not one canal, but a system of canals and rivers connected together. It's still an important part of the transport system in China. Thousands of boats use it every day to transport grain and many other types of cargo(货物).

Now the Chinese government is doing new work on the Grand Canal. It is making parts of it deeper, so bigger ships can use it. The canal will also help to move water. There is a lot of rain in the south of China, but not as much in the north. The canal will carry millions of litres of water from the south to the north.

The Grand Canal is much less famous than the Great Wall, and not very many tourists visit it. But it's possible to go on a cruise(乘船游览)along some of the oldest parts of the canal. Passengers on these cruises see beautiful parts of China that other visitors don't see.

Many people enjoy watching movies in a cinema. They think the cinema has a better atmosphere（气氛）to enjoy the movie. However, I think people are happier and freer when watching movies at home. 

Watching movies at home is more comfortable. To watch movies in a cinema, you have to buy a ticket before you go there for a better seat. However, there is no need for people at home to worry about the ticket. They can enjoy movies at any time they like and with the most comfortable seat. What's more, people watching movies at home wouldn't have to face any traffic problems. 

It is free to watch movies at home. In the cinema, we can't go outside and do something else because the movie won't wait for us. Sometimes we miss part of the movie. At home, we can pause（暂停）at any time and go back to watch the part. 

All in all, a cinema is a good place to watch movies, but it isn't the best place to enjoy the movies. I think watching movies at home is better. 

All clever people know that it takes some time to make your life better. This doesn't mean that you can't make small changes to make your life better in a few weeks or in a few days! Here is some helpful advice.
