House fires cause many deaths each year and a large number of these fires are unfortunately set by children.{#blank#}1{#/blank#}Kids must understand that they'd better not play with fire. You should keep matches and lighters out of their reach.

{#blank#}2{#/blank#} The main job of such an alarm is to protect you while you're asleep. You should have a smoke alarm outside each bedroom and on each floor of your home. You ought to have two plans for getting out of your house if there is a fire and practise these plans in the dark with your family.

A smoke alarm warns you of the danger. {#blank#}3{#/blank#}Take action immediately. When you come to a closed door, check it with the back of your hand. If it feels hot, there may be smoke or fire behind the door, so take care. Once you are out of your house, call the fire department from a neighbor's house. If a family member or a pet is caught inside, you shouldn't go back in. Firemen know how to perform rescues safely.

{#blank#}4{#/blank#} Change the batteries at least once a year. You should use the test button each month to see if the alarm and batteries are still working. A smoke alarm lasts about ten years. You ought to change it even if it seems to be working.

Winter sports need to be in cold places. Have you ever imagined one day people go to other planets to hold the Winter Olympics?

Weeks before Tomb-Sweeping Day on April 4 this year, hundreds of qingtuan were sold each day. The snack was still a must-have for many people. 

In the southern part of China, eating qingtuan at the beginning of spring is a kind of tradition. Chinese people started to eat it more than 2, 000 years ago. It is made of sticky rice(糯米) and red bean paste(红豆沙), and is famous for its softness, freshness and sweetness. The secret behind its mouth-watering taste is one of its materials—mugwort leaves (艾蒿叶). The plant is mainly found in the Yangtze RiverDelta(长江三角洲) where it has perfect conditions to grow. 

People in this area usually put qingtuan on the tombs(墓) of their dead family members to cherish the past memory. Making qingtuan is also a chance for family members to get together at home. It really takes time and effort to make the snack. 

Now, qingtuan has already spread its special taste to the northern part of China. Li Yuan, a 30-year-old engineer who grew up in Zhejiang Province, brought qingtuan back to Beijing where he works. "It tastes different in and out of my hometown, "he said. "There's no place like home. "

Qingtuan has many different tastes inside it, such as apples and bean milk, to meet customers' tastes. The difference of the taste shows that it's getting more and more popular across the whole country. 

Even though there is warm weather and green leaves in spring, the season wouldn't be complete without a taste of qingtuan. 

There is a competition for photographers (摄影师) of wildlife in the Natural History Museum in London every year. This year, the competition had about 50,000 photos.These photos come from different parts of the world. They take us underwater, deep into the woods, and high above cities. All of them show different kinds of life on earth.

In the end, the great prize went to Laurent Ballesta. The French photographer won the prize for his photo of a horseshoe crab. In the photo, the horseshoe crab looks for food in the sea. Three little fish follow it closely. They may hope to eat what the horseshoe crab misses.

Horseshoe crabs are known as "living fossils (化石)". They have lived for at least 445 million years and stayed almost unchanged. They're now in great danger, however. What happened to them? In the 1960s, scientists found something surprising. The blue blood of horseshoe crabs can be used for scientific study. As a result, hundreds of thousands of them are caught each year.

For a long time, Ballesta took photos of horseshoe crabs in the sea. His winning photo took the judges (评委) by surprise. "To see a horseshoe crab so alive and well, in such a beautiful way, was fantastic," said one of them.

Do you believe picking up rubbish has become a world competition?

In November of 2023, the first Rubbish Collection World Cup {#blank#}1{#/blank#}(hold) in Asia. Teams from 21{#blank#}2{#/blank#} (country) took part in it. According to the rules, each team will have 60 minutes to collect rubbish as much as possible. Britain {#blank#}3{#/blank#}(final) won the first prize. "We hope more people around the world will pay attention to {#blank#}4{#/blank#} (environment) problems, " said a British team member. 

When Ken, the founder (创始人) of the competition, was interviewed, he talked about how he came up {#blank#}5{#/blank#} the idea. Several years ago, he found many sea animals died {#blank#}6{#/blank#}of the rubbish in the sea. So he started to pick up rubbish on his way to the beach every morning. 

"Picking up {#blank#}7{#/blank#} piece of rubbish may save a turtle's (海龟的) life. It's also a good way to keep the beach clean. " In his eyes, changing {#blank#}8{#/blank#} (people) thoughts about rubbish was more important. 

"Picking up rubbish is meaningful and {#blank#}9{#/blank#}(help), " added Ken. "Now, I am glad to hear that lots of people take part in it {#blank#}10{#/blank#} (protect) our environment. "
