In this April, some people reported they felt the shake of earthquake. Earthquakes happen suddenly, without warning.
Everyone in your home should know what to do if an earthquake happens.
During an earthquake, most deaths and injuries are caused by falling heavy objects. You need to pick a safe place in each room of your home.
Remember to fix things that might fall from above during an earthquake. Falling things, like televisions and books, can cause damage or injury. Move large and heavy things to lower shelves. Hang heavy items, such as mirrors, away from beds and sofas.
If you are outdoors, find a place away from buildings, trees and streetlights. If you are in an elevator (电梯), hit the button for every floor.

Do you want to get good grades? The following advice may help you to get a better one.
You’d better make sure you’re sitting in a proper seat so that you can pay attention to your teachers. Tell your teachers or parents about any problem that is bad for your attention in class
Try to write down what your teacher says or writes on the blackboard. It's best to write in a neat way so that you can read your totes later.
It is not a good habit to put off what you can do today till tomorrow. It’s bad for your study. In fact, the best way to study is to plan ahead.
If you don’t know how to solve the problems at school, you can ask your teacher for help. If you’re at home, our parents might help you.
If you have a test tomorrow, but suddenly you can’t remember anything, not even 2+2, don’t worry. Try to get a good night’s sleep and you’ll be surprised at what comes back to you in the morning.
For the curious hacker (黑客) who has gained access to your online account, this is the same as locking your door and leaving the key under the doormat (门垫).
To create a safe password that is easy to remember, follow these simple steps:
● You should never use personal information as part of your password. It is very easy for someone to guess things like your last name, pet’s name, child’s birth date and other similar details.
● There are tools available to help attackers guess your password. With today’s computing power, it doesn’t take long to try every word in the dictionary and find your password, so it is best if you do not use real words for your password.
● You can make a password much safer by mixing different types of characters. Use some uppercase letters (大写字母) along with lowercase letters (小写字母), numbers and even special characters such as “&” or “%”.
● Rather than trying to remember a password that is created using various character types and is not a word from the dictionary, you can use a “passphrase”. Think of a sentence or a line from a song or poem that you like and create a password using the first letter from each word.
For example, rather than just having a password like “yr $ 1 Hes”, you could take a sentence such as “I like to read the About. Com Internet network security website” and convert it to a password like “il2rtA! nsws” by using the number “2” for the word “to” and using an exclamation point (感叹号) in place of the “I” for “Internet”. You can use a variety of character types and create a safe password that is hard to figure out, but much easier for you to remember.
● You should use a different username and password for each login you’re trying to protect. That way, if someone figures out one of your passwords, the others are still safe. Another approach, which is less safe, but provides a fair balance between security and convenience, is to use one username and password for sites and applications that don’t need the extra security, but use unique usernames and more safe passwords on sites that require more security, such as your bank’s website.

【推荐1】Earthquakes, floods, hurricanes(飓风), tsunamis(海啸)—It seems that everyday we read about at least one of these somewhere in the world. But every year, somewhere, another kind of disaster causes great damage to plants and people. It’s something much smaller and not so well-known as an earthquake or tsunami. It’s an insect called the locust(蝗虫).
The locust usually does things alone—it lives on its own and eats on its own. But sometimes, something changes the way nature works. When the number of locusts increase somewhere and there are lots of plants to eat, the locusts get together in “swarms( 一大群、泛滥)”.
Perhaps the most dangerous locust is the desert locust. It is found in Africa, the Middle East, and Asia—in about 60 countries altogether. When desert locusts swarm, they bring problems to one-tenth of all the humans in the world.
The numbers are huge and frightening. A swarm of desert locusts can be 1,200 square kilometers in size. Imagine an area that is over 20 kilometers wide and 50 kilometers long, full of locusts. And there can be 50 million locusts in each square kilometer. Each locust eats its own weight in plants every day, so a swarm of desert locusts can eat more than 150 million kilos of food in one day. They can also fly very long distances. In 1954, a swarm of locusts from northwest Africa flew thousands of miles to finally land in Great Britain.
It’s no wonder that farmers in many countries of the world fear the desert locust more than snakes and spiders. It’s the desert locust that destroys the harvest and bring hunger to people all over the world.

【推荐3】As climate change gets worse, global temperatures increase, and so does the risk of wildfires. A recent report from the United Nations shows that wildfires are becoming more common and severe. Wildfires have caused many problems across countries. These fires destroy (毁坏) homes and businesses, take lives and also damage the environment.
A wildfire in New Mexico, a state in the southwestern US, burned for nearly two months in 2022, damaging more than 1,275 km2 of land—an area about the size of the city of Los Angeles. Wildfires have created seasonal pollution in the northwestern US. Between 2002 and 2018, carbon monoxide (一氧化碳) levels increased every year for the month of August in the area.
In 2019 and 2020, Australian wildfires filled the air with deadly clouds of smoke and killed thousands of koalas. Around 437,000 people had to take in air with a PM2.5 concentration (浓度) of at least 25 mg/cm3 of air. That’s more than the 15 mg/cm3 of air that the World Health Organization (WHO) considers acceptable.
In the last 10 years, the total number of forest fires in China every year has increased to more than 2,000 cases. Wildfires lead to great loss of animals, forests and people. What’s worse, some animals become endangered and some people have to move to other places to live. Greater Hinggan Mountains (大兴安岭) is one of the important forestry places in China. The government uses mountain watchtowers, forest cameras and aerial drones (无人机) to prevent forest fires in summer.
