Many years ago, most of our earth wascovered with blocks (块) of ice. These iceblocks were as tall as high buildings in modern cities. Most of the ice was inthe northern part of the world. Then the ice blocks started to move south. Coldand rain came with the ice. Animals had to move. At last, the ice began to melt(融化). After half a million years, most of it melted.More than half of the earth became covered with water. Theclimatebecame much warmer. Things began to grow. The earth began to look the way inwhich it looks today.

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.

Have you ever imagined Li Bai and Du Fu, two ancient Chinese poets of the Tang Dynasty, standing in front of you? At the World Robot Conference in Aug12th, the two "poets" both {#blank#}1{#/blank#}(show) up in the form of human-like robots. Dressed in {#blank#}2{#/blank#} (history) costumes. "Li Bai" was reciting his famous poem Invitation to Wine {#blank#}3{#/blank#} ‘Du Fu' was sitting beside him and listening {#blank#}4{#/blank#} (careful) with a smile on his face. 

The seven-day event took place in Beijing in August with nearly 600 kinds of robots around the world. It was {#blank#}5{#/blank#} (they) first public show for about 60 of them. 

The two "poets" developed by EXROBOTS were the most popular. They not only look like humans but also can understand human languages and follow {#blank#}6{#/blank#} (direction). They can express feelings such as joy, anger and {#blank#}7{#/blank#} (sad). Pet-shaped robots also drew a large number of visitors. The CyberDog 2, for example, do flips (空翻) and many other tricks {#blank#}8{#/blank#} a real dog. A robot cat named MetaCat with blue eyes {#blank#}9{#/blank#} soft hair will shake its head when people touch it. 

 "The robot industry will continue to make progress. "Xin Guobin, ‘vice-minister of industry and information technology, said, "And robots should play an important role in {#blank#}10{#/blank#} (deal) with common challenges in this world. They will make people live a better life in the future. 

 Good sleep is really important to our health. But global heating is leading to increases in night-time temperatures that are happening faster than they are during the day. This makes it harder for us to get quality sleep. As global temperature increases, the average global citizen is already losing 44 hours of sleep every year, a recent study revealed. 

 The study used sleep and outdoor weather data collected from 2017 to 2022. It found that higher temperatures reduced sleep by putting off its onset. People's bodies need to cool every night as they fall asleep, but this is harder to do when it is warmer. 

"Some groups, however, will be affected much more than others. " said Kelton Minor,  a researcher from the University of Copenhagen. The sleep loss per degree of warming is about a quarter higher for women than men, twice as high for those over 65 years old, and three times higher for those in less wealthy nations. 

"Women usually have higher levels of fat than men, which may make the cooling time longer. Older people are known to sleep less at night and have poorer body temperature regulation(调节). People in poorer nations could lose more sleep, as it's harder for them to get cooling machines. " he explained. 

 The studies have also shown that rising temperatures hurt health, including increasing the possibilities of heart diseases, mental health problems, accidents and injuries. They have also been found to reduce one' s ability to work and study. Poor sleep has also been shown to have these effects. However, disturbed sleep may be a key reason why researchers are seeing these heat related health problems. 

 Worryingly, there were no signs of people being able to adapt to hotter nights. The growing numbers of people in many countries around the world are simply not getting enough sleep. 

There are four students talking about their healthy living. 

Anna: I went to the hospital to c{#blank#}1{#/blank#} my heart. My doctor advised me to do more sports. However, I hate sports. To my surprise, my parents gave me a dog as my birthday gift. I had really wanted one! Since t{#blank#}2{#/blank#} , I've become healthy because I take him for a walk every day. 

Wang Wei: My teacher planned to found a girls' football team. I thought that was a great idea, and I was the first one to j{#blank#}3{#/blank#} the team! It has been one year since we played football together, and it has improved our fitness! Our teacher is also fit now because she is not only the coach, but also takes part in the t{#blank#}4{#/blank#} with us!

Thomas: For the last few years, I went to work on the underground. When I got to school, I was not happy and felt tired and s{#blank#}5{#/blank#} . But since I b{#blank#}6{#/blank#} a bike in January, I go to school by bike every day. Now, riding to school has become my d{#blank#}7{#/blank#} exercise. I feel much better and happier than before. 

Richard: I was not feeling w{#blank#}8{#/blank#} for a long time and I got weaker than before. So I decided to do more sports. One of my friends s{#blank#}9{#/blank#} that I should go for a run before school. We began running a week ago, but I really didn't like it. When I got to school, I felt terrible. My legs h{#blank#}10{#/blank#} , and I felt pretty hot. Maybe doing sports isn't for me right now. What do you think?
