【推荐2】What is a tsunami(海啸)? Tsunamis are often caused by earthquake s or volcanoes(火山). The average speed(平均速度) of the waves(波浪) is 300 mph and the waves can last from five minutes to an hour.

What to do in a tsunami?

Firstly, when a strong earthquake is felt, leave the water at once, get to the shore(海岸) and go as far away as you can from the beach fast. If it allows, go to a higher ground.

Secondly, turn on the TV for news and weather report. They will tell you more about the tsunami.

Thirdly, get all members of your family together and let everyone know the tsunami is coming. Choose a place to stay together. Make sure the place is safe and go as far away from the shore as possible. Bring emergency supplies(应急用品) when you have to leave your house.

At last, if you find a huge wave is coming, climb onto the roof of your house or on the highest point of the nearest building. Hold on to anything that’s strong enough. Climb a tree if you have to.

For a tsunami, the only way to survive(幸免于) it is to be prepared.

【推荐3】On August 4th, two men and two women were hit by lightning while visiting Washington’s Lafayette Square, just north of the White House. All four people were taken to the hospital quickly. Three of them later died.

Take lightning storms seriously. If you’re outdoors, it is important to know how to keep away from lightning.

When thunder roars (咆哮), go indoors. Quickly go into a room such as a shopping center, home, or office.

Are you in an open area? Make sure that you’re not at the highest point, especially when you’re in an open area. Look for buildings not in high places, at the same time, being careful not to get caught in water.

Are you in a car? If you’re in your car during a lightning storm, close your windows and keep an eye out. Stop the car when you can’t see the road.

Are you around water? Keep away from water and don’t swim or row a boat if a storm is nearby. If you’re on the water, leave it quickly.

________ Don’t take shelter (遮蔽) under a tree that is isolated or the tallest nearby.

Keep away from flash floods (骤发洪水). Lightning storms can be followed by heavy rain that could lead to flash floods. Be careful when you’re looking for a shelter in a low place.

Don’t touch metal items and other special things. These things, such as bikes, power lines, and golf clubs, can conduct electricity.

First, you should find a bamboo cane （条，竿） that is about your own height. When choosing the bamboo cane for your fishing rod, find one that is straight, easy to hold onto and light enough to carry. Using a bamboo cane that is too long and heavy will make it difficult to transport. If it's too short, you can't catch a fish with it.

After you find a good bamboo cane, you must remove the leaves and outer bark or “skin". You will be left with a cane pole. The third step requires you to use sandpaper and make the cane pole smooth.

The fourth step is to dry out the cane. Depending on the temperature and humidity, it may take anytime from three weeks to three months to dry properly. Do not leave it in direct sunlight or it will get too dry and can easily break. Test if the cane is dry by swinging （摆动） it in the air and making sure it doesn't break or bend.

The fifth step is to attach the fishing line to the end of your fishing rod. The length of the fishing line should be as long as the rod itself, plus an extra half meter. You need to be careful when tying the fishing line to the pole. Don't tie it too tightly or too loosely. The final step is to attach the fishing hook and small weight at the end of the fishing line.

At last, your fishing rod is ready to be used for fishing!

Parking near their companies for five days a week could cost them a lot of money. At the same time, even with prices for parking lots in residential areas(居民区)rising, most of their spaces remain idle during workdays. Now a new form of sharing economy has appeared in China—the shared parking space. It has become a huge market in some big cities.

In Qingdao, a coastal(海岸的) city in Shangdong, up to 10, 000 personal parking spaces have been turned into shared ones with the help of "Airparking", an online shared parking platform developed by a network company from Guangzhou

Through a special app, users can either share or order a parking place. Owners who have idle parking spaces can share some information, including the parking position, license number and time limit(限制) on the platform. With the information, users can easily find the nearest place to park. The average(平均的) parking cost for shared parking is 4 yuan each hour, almost the same as the service cost in traditional parking spaces.

Qingdao is one of the Chinese cities that encourage shared parking. Some other big cites, including Beijing, Shanghai and Hefei, have also begun to try this idea. The Shanghai government, for example, has set up more than 6, 500 shared parking spaces to encourage the public to use. Shared parking will be more and more helpful to the drivers
