On March 31", 2019, a wildfire in Liangshan Yi autonomous prefecture(凉山彝族自治州)led to 31 deaths, including 27 firefighters. And on May 1st, 2016, in Alberta, Canada, a wildfire destroyed an area of nearly 700 square miles. More than 88, 000 people had to leave their homes and thousands of homes were destroyed.

    Wildfires are unexpected, unplanned. And the cause of most wildfires is unsure. To bum, wildfires require the right conditions—fuel, oxygen and heat. And global warring is one of the most important reasons. The high temperatures and dry conditions make the fire spread quickly.

    In many parts of the world, wildfires happen naturally. They are started by lighting(闪电)or some other special weather conditions. In recent years, there have been more wildfires because of dry, hot weather, and changeable weather patterns because of global warning.

    However, many fires are started by people. Sometimes, people clear land for farming. Besides, there are smokers who accidentally set fires.

Wildfires can cause a lot of smoke, which will pollute the air. Lots of lives, property(财产)and valuable forests will soon disappear in wildfires. When trees are burnt down, and heavy rain follows, more disasters such as terrible floods will happen.

    It was Jimmy's birthday, and he was five years old. He got a lot of nice birthday gifts from his family, and one of them was a beautiful drum. "Who gave him that thing?" Jimmy's father asked when he saw it. "My father did," answered Jimmy's mother. Jimmy liked his drum very much. He made a terrible noise with it, but his father didn't mind. He was working during the day and Jimmy was already in bed when he got home in the evening, so he couldn't hear the noise. But one of the neighbors(邻居) didn't like the noise at all, so a few days later, she took a knife and went to Jimmy's house while he was hitting his drum. She said to him, "Hello, Jimmy, there is something very nice inside your drum. Here is a knife. Open the drum and let's find it. ""No, I know there isn't anything in it, "said the boy.

It is easy for many people to catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can't they find a cure for the common cold? The answer is easy. There are actually different cold viruses out there. You never know which one you will get, so there isn't a cure for each one.

When a virus attacks your body, your body works hard to get rid of it Blood rushes to your nose and causes a block in it. You feel terrible because you can't breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells. You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.

Different people do different things to deal with colds. In the United States and some other countries, for example, people might have chicken soup to help them get over the cold. Some people take hot baths. Other people take medicine to stop different symptoms(症状)of colds.

There is one interesting thing to note一some scientists say taking medicine when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't have a way to fight it and kill it Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:

It takes about one week to get over a cold if you don't take medicine, but it takes only seven days to get over a cold if you take medicine.
