Computers can injure(伤害)you. Most other injuries happen suddenly．For example，if you fall off a bike and break your arms, it happens very quickly. But computer injuries happen slowly．
You probably know how to ride a bike safely. Now learn to use a computer safely．

Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be more than 50 centimeters from the screen. Don’t forget to look away from it sometimes. This gives your eyes a rest．
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on(反射)the screen. If the window is in front of you，the sun and the screen will both shine into your eyes．
Your hands and wrists(手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something.
2) Keep your elbows(肘)as high as the keyboard.
3) Stop sometimes and exercise your hands, wrists and fingers in a different way．
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you shouldn’t bend your back when you sit. The top part of the screen should be in front of your eyes. Your forearms, wrists, hands and the upper part of your legs should all be parallel(平行)to the floor. If you are sitting for a long time, get up every half an hour and exercise your arms, legs and neck．
Enjoy your computer, but use it safely．

Robot driving coaches (教练) “nicer” than real ones

       Students at a driving school in Zhenjiang, East China’s Jiangsu Province say robotic coaches have removed some of the stress when practicing.
       The robotic coach which provides automatic voice navigation (自动语音导航), gives learners gentle voice orders.
       “I’m nervous when a real coach sits beside me. This robot is nicer. Even if I do something wrong, the robot will continue to encourage me, instead of blaming me.” a student of the driving school told China Daily. The robot can be set to a teaching mode or stimulated test mode. It will tell drivers if they’ve passed the test. “The robot will remind learners to turn on their left turn signal as the car approaches a left turn. If it is about 20 centimeters away from an obstacle, the car will automatically stop.” said a coach at the driving school.
       The school doesn’t plan to cut the number of human coaches.

I looked out at the smiling faces packed into the school gym. The applause filled my ears. I had done it. I had really done it! I found a new person inside me,   a much more daring,   outgoing person who had been hidden all along, just waiting for the ______ to emerge（出现）.

Just a few months earlier, it was impossible to ______ myself acting in a play in front of two hundred people. But without my teacher, Mrs. Sather, I couldn't get that opportunity.

One day, she announced, "Our class was going to ______ a play. Anybody, want to try?"

A few excited hands shot up-mine, of course, was not one of them.

After school she stopped me and invited me for a talk. Puzzled, I followed her to her desk. She said,   "I think you are ______ for the lead character. But I was surprised you didn't raise your hand."

Me, the lead? Was she crazy?

Mrs. Sather gazed into my eyes as if seeing my inner _______ locked away inside. "But I'd like you to give this a try for me, " she continued. "If you reach for the stars,   you might at least grab a piece of the moon.

I realized it was time to throw off ______ and show the world who I really was. I looked Mrs. Sather right in her sparkling（闪亮的）blue eyes and said, "OK. I'll try."

In the following months, in spite of fears, I did everything I could to ______ I could do it in practice.

At the end of the play, when the audience applauded,   I knew they were not just cheering for my performance that night,   but for the performances they knew would come in later years because of my newfound confidence.

Many young people all over the world love to travel and see the world. Have you heard of backpackers? They are normally young people who travel cheaply with just one bag and comfortable walking boots. They buy local food in supermarkets to save money and at the same time become friends with local people.
Some people prefer adventure tours. Brave people may try bungee(蹦极) jumping from the bridge overlooking the Victoria Falls in Africa with only a rope around their legs. Some enjoy the challenge of rock climbing in the Alps in Switzerland. Others may go ice skiing in the Rocky Mountains in the USA.
Have you ever heard of an ecotourism (生态旅游)? It means a holiday in which people come close to nature but are very careful not to destroy the nature beauty or living things in the area. How can this be possible? Let's read an interview with people who enjoyed a swimming with dolphins tour.
Interviewer what was the most exciting part of your holiday?
Sharon from South Africa I felt excited when I heard the sound of wild dolphins beside me in the water and then swimming directly under me. An image I will never forget.
Xavier from Portugal There were two dolphins below us swimming downwards. One stopped and looked back at me as if to say “What are those strange things?” Fantastic!
Interviewer Did you feel that your holiday helped local people and areas to keep their beautiful environment?
Jane from New Zealand The hotel and the whale and dolphin watching companies hire local people. They used to hunt those whales and dolphins, but now they can earn money from tourism and mustn’t kill whales and dolphins. Not many boats are used at the same time so these animals aren't disturbed. The boat companies also work to educate the local schools about the importance of protecting these wonderful animals.
Helen from England I am glad they are not killing the whales and dolphins any more, but the cars and boats use fuel(燃料) which could cause pollution and make the sea dirtier.
Well, what do you think? Thousands of people visit the Forbidden City or the Great Wall of China every year. Do you think that's a good thing, or do you feel that China's important tourist attractions can be affected? Are there any ways of sharing your treasures (珍宝) but keeping them in good condition?

Risa in Roma, Italy is chatting online with his friend Xiaoming, who has just moved to Beijing, China with his family. After a little while, Xiaoming tells Risa that it’s time for him to go to bed. Risa looks outside to see the sun shining and is confused why Xiaoming would go to bed when it’s so early! “What time is it?” Risa asks. “It’s 9:00 pm!” Xiaoming replies. What’s going on here? Is it some kind of time travel?

In fact, it is NOT. This is actually just something that happens every day to our planet. Risa and Xiaoming are having different times because Xiaoming is now in a different time zone.

A time zone is an area on Earth that has a specific time that all the people in that area can set their clocks to. You’ll pass through different time zones if you travel from east to west (or west to east) on the surface of Earth. Humans came up with the idea of time zones and decided which parts of Earth are in which time zones in the 1880s. The world now has 24 time zones and each time zone is one hour ahead (领先) or behind its neighboring ones. You can see part of these time zones on the map below. The numbers on the map show how many hours you must add to or subtract from the Greenwich Mean Time (格林威治时间) to get the local time.

Most countries, such as Ireland and Japan fall in one zone. Some large countries such as the U.S., Canada and Russia may be divided into three or more time zones. But China is the only large country besides India that only uses one time zone.

We need time zones because Earth is like a ball. Each day, Earth completes one full turn. As it turns, sun shines on only one part of it at a time. While the sun shines where you live, you are having the daytime, but it’s nighttime somewhere else. It would be silly if people all over the world used the same time.

1．Why does the writer mention the story of Risa and Xiaoming?

A．To share this interesting story.

B．To introduce the topic of time zones.

C．To give an example of time travel.

D．To explain how Earth completes a full turn.

2．In Risa and Xiaoming’s story, when it’s 9:00 pm in Xiaoming’s city, what time is it in Risa’s city?

A．2:00 pm

B．4:00 am

C．1:00 pm

D．5:00 am

3．Why do we need the world time zones?

A．Because the world time zones can make time longer.

B．Because it is boring to have just one time zone.

C．Because not all the places can be in the daytime at the same time.

D．Because there are too many countries in the world.

4．Which of the following is TRUE?

A．If you travel from north to south on the surface of Earth, you will certainly pass through different time zones.

B．Time zones are something that naturally happens.

C．China is the only large country in the world that only uses one time zone.

D．Different cities in America may be using different time zones.

5．According to the passage as well as the time zone map, if you know the Greenwich Mean Time, how can you work out New York’s time?

A．By adding 5 hours to the Greenwich Mean Time.

B．By multiplying the Greenwich Mean Time by 5.

C．By subtracting 5 hours from the Greenwich Mean Time.

D．By dividing the Greenwich Mean Time by 5.

Pompeii is an ancient city in Italy. It is famous for having been suddenly buried (埋葬) in 79 A.D. by a volcano located nearby named Vesuvius. Though thousands of people escaped, over 1,100 people were killed almost instantly in the extreme heat that was released by the volcano. They were quickly covered by small rocks, ash and dust from the volcano.

People began excavating (挖掘) Pompeii in the mid-1700s. Over the years, scientists have discovered more and more about the life of these people who were sadly frozen in time.

Archeologists (考古学家) have discovered theaters, swimming pools, gyms, hospitals and many different kinds of stores in Pompeii. They’ve also found restaurants, including about 80 “fast food” restaurants called thermopolia, which served hot food and drinks to people on the streets.

In 2019, archeologists working for the Archeological Park of Pompeii announced that they were working to excavate a well-protected thermopolium. Because the restaurant was in such great shape, they decided to excavate the whole area.

“This is so exciting,” said the director of the archeological park. “It is the first time that we are excavating an entire thermopolium.”

A thermopolium has a long, low counter with lots of clay pots built into it to hold its store of food and drinks. What was special about this one was that even the pictures on its counter walls were still in almost perfect condition—almost exactly the way people would have seen them thousands of years ago.

Some of the paintings on the walls show ducks and roosters—examples of the food that could have been served at the snack bar. They even found a duck bone in it.

The scientists discovered many large clay jars, which held food and drinks. Two jars held fish and pork. They also found a mixture of snails, fish and lamb, which they believe may have been some sort of soup.

At least one of the jars held wine. “It was so strong that we could smell it through our masks,” said one of the archeologists. They expect to learn even more about the contents of the jars once they are finished being carefully studied in a laboratory.

The archeologists say they are really just beginning to understand all that they can learn from this thermopolium. Because the site was so complete, they expect it to reveal (揭露) many more of the hidden secrets of Pompeii.
