1 . While fake (虚假) news can take many forms, it can be divided into two broad types: misinformation and disinformation.
Misinformation Misinformation is when false information is shared by someone who believes that information to be true. Normally it isn’t done on purpose. | Disinformation Disinformation is when misleading or even false information is shared with the intention to deceive (欺骗) others. |
There are lots of reasons why people share fake news. Often the person sharing it doesn’t realize that it’s fake. Sometimes it’s done to advertise a service or product, so that someone can make money. It could even be done to make people laugh.
Fake news can also be shared by someone who wants others to hear their own personal opinions and be affected by them. Still, fake news is shared to influence the opinions and beliefs of others about organizations and business.
Fake news? Question it!
To work out whether the “news” we are reading is fake, we can use our critical (批判性) thinking skills to ask ourselves the following questions.
Is it a mistake or just a joke?
People sometimes share information, believing that it’s true, because they don’t realize that it’s a joke. It might even be April Fools’ Day!
Are there lots of spelling and grammar mistakes?
If yes, it’s a sign that no one is checking the content. This could mean that those writing the content are not professional writers or journalists and the news content is untrustworthy (不可靠的).
Is the article advertising something?
Sometimes a news article can influence us to buy something. Companies will often pay a news organization to talk about their product as if it’s “news” to encourage people to buy it.
Is the headline believable?
Sensational (耸人听闻的) headlines encourage us to click on a story because they catch our attention. Some people get paid for every click, so before clicking, ask yourself, does the story sound made-up, or even impossible?
Is there bias (偏见)?
Sometimes certain facts have been left out of a story because the writer wants the readers to believe it. Bias is an underlying (隐含的) opinion that guides our actions. See if you can fact-check the story with another news source if you’re unsure.
When fake news causes stress or hurt to the person or people it targets (将……作为目标), it is often the case that those who have helped spread it will claim they were not to blame. However, sharing fake news is just like adding fuel (燃料) to a fire. If the false information doesn’t get shared, it doesn’t get seen and cannot fulfil its purpose. When it comes to fake news, it’s not enough to not write something, we must refuse to share it, too.

We’ve all heard people say, “Oh, that person is so creative!” about someone who is great at art. But art is just one area where people can be creative.
Any time you try something different to deal with a problem, you’re being creative. In sports, that might mean trying new moves to score a goal. In engineering, that might mean joining different materials together to make a container that will protect an egg. At home, it could mean working out a shortcut to get to your friend’s house. You are creative every day!
Are some people naturally more creative than others? Maybe, but anyone can get more creative with practice. Here are some methods that work for experts who are creative in very different ways.
Explore and imagine
Shigeru Miyamoto is the brains behind some of the world’s most popular video games, such as Super Mario Bros. He exercised his creativity (创造力) like a muscle (肌肉) when he was growing up near Kyoto, Japan. He spent hours exploring nature and going on adventures (历险) in his mind. As a game designer, he still finds joy in making up new worlds and adventures.
Make wacky mash-ups (混搭)
Dr. Neri Oxman and her team at the Massachusetts Institute of Technology’s Media Lab combine things that don’t usually go together. They mixed ideas from robots and insects when they invented small robots that spin fibers (结网) the way silkworms (蚕) do. In the future, their work may lead to groups of robots that quickly build many types of buildings.
If you come up with ideas you’re not sure about, don’t worry-you’re not alone. In the Netflix series Abstract, Dr. Oxman said she often doubts her ideas. “My father said, ‘When you create, you must always feel a little bit uncomfortable. And if you’re feeling uncomfortable and alone, you know you’re doing something right. ”
Find pictures in patterns
Have you ever looked for animal shapes in clouds? The artist Leonardo da Vinci looked everywhere for patterns that would spark his imagination. He wrote that artists should look at stone walls and irregular stains (不规则的污渍) to discover landscapes or strange faces and costumes, and an endless variety of objects. You could reduce these to complete and well-drawn forms

3 . We watch our salt and fat intake to protect our hearts. We put on sunscreen (防晒霜) to protect our skin. But what can we do to protect and care for our eyes? As it turns out, quite a lot.
Wear glasses. When in the sun, we should wear sunglasses to protect our eyes from ultraviolet (紫外线的) light. When doing things that have the risk of hurting our eyes, we should wear special glasses. For example, when running in the woods, we should wear sports glasses to avoid getting our eyes hurt by branches.
Take a break from screens. Staring (盯住) at a screen can easily make our eyes dry and tired, and our eyesight worse. Take a break every 20 minutes to look into the distance for 20 seconds. It’s a great way to relax our eyes.
Eat right foods. Research shows that foods rich in vitamin (维生素) C, vitamin E, zinc, lutein, zeaxanthin and omega-3 fatty acids are good for reducing the risk of many eye diseases.
Stop bad habits. First, stop smoking. Smoking is terrible. It isn’t just bad for our lungs! It can harm our eyes, too! It causes dry eyes and makes eye disease worse. Also, try not to rub (摩擦;揉) our eyes. Rubbing makes inflammation (炎症) worse.
Repair the air. Indoor heating and air conditioning can dry out our eyes. Outdoor cold and wind can be drying, too.
See an eye doctor for a checkup. Not all eye problems are noticeable, but it’s best to find and treat them as early as possible.

Do you know how many kinds of plants and animals there are in the world? Experts believe there are between 8 and 14 million, but right now we only know about 1.5 million. However, scientists are finding new plant and animal species (物种) all the time—and that’s good news for us.
In 2009, a university professor named Christopher Austin and his student Eric Rittmeyer discovered a new animal species. They were in Papua New Guinea, studying the wildlife on the island. One evening, they were in the jungle listening to animal sounds. The most common sound was the noise of frogs croaking loudly. But there was another sound—a much softer, high-pitched one that sounded like it came from something much smaller.
At first, they couldn’t locate the sound, but after some time, they realized it came from the ground. They searched through the grass and dead leaves carefully, but what they found surprised them. It was a tiny frog—just seven millimeters (微米) long. “This frog has a call that doesn’t sound like a frog at all, ”said Austin. The frog they discovered was the smallest in the world!
Researchers believe that frogs are important because they help keep the environment clean. We can also use them to create new medicines. Whenever we find a new species, we learn new things. For that reason, scientists work very hard to find new plants and animals every day. But their jobs are getting more difficult. The forests that these animals live in are disappearing quickly. And, sadly, so are the animals.

5 . Knowing how to stay safe at home is just as important as knowing the family rules. Again, this is something you need to talk over with your mum, dad, or both of them. Go over safety rules for the kitchen if you’ll do any cooking while you’re home alone. It’s a good idea to practise what you would do in a real emergency, just in case something terrible happens.
Kids who are home alone might worry that someone could break into the house and hurt them. The good news is that this is very unlikely. But keeping the doors and windows locked will help you stay safe.
Decide with your mum or dad what to do if the phone rings or someone knocks at the door. It’s never a good idea to tell someone that you’re home by yourself. And when you get home and find the door is open or a window is broken, don’t go inside. Instead, go to a neighbour you trust and ask for help.
Other kinds of emergencies could come up too, like a fire, or you or a brother might get sick or hurt. Just in case, you’ll need to know:
◆how to dial 911
◆your address and phone number
◆the name, address, and the phone number of the place where your mum or dad works
◆the name, phone number, and address of a trusted neighbour
1. The underlined word “emergency” in the first paragraph means “________” in Chinese.A.急救 | B.紧急事件 | C.导火索 | D.情况 |

6 . Fraser Island is in Queensland, Australia, about 200 kilometers north of Brisbane. It is about 120 kilometers long and 240 kilometers wide. It is a very important island because it is completely made of sand. In fact, it is the largest sand island in the world. There is no airport on the island, but there is a long beach along the east coast. Planes arrive and leave from here.
The sand makes unusual shapes. There are hills made of sand called sand-blows. Nothing grows on them. They move one or two meters a year from the northwest towards the southeast of the island, getting bigger and bigger. At other places on the island, such as Rainbow Gorge, the Cathedrals and Red Canyon, the sandy rocks have different colors. Sometimes the rocks are so brown that they turn the sea brown, like coffee.
Surprisingly, the sandy island has a lot of different plants and animals. There are dark forests-eucalyptus woods, beautiful flowers and over a hundred lakes. There are many kinds of birds, like owls and curlews. There are many animals there, too, such as crocodiles, flying foxes and wild dogs called dingoes.
About 500, 000 people visit the island every year to see the island’s beauty and nature. People enjoy camping and hiking there. Unluckily, the visitors create problems. They damage plants and frighten animals. Their sun cream (防晒霜) makes the water dirty. So it is necessary to manage the visitors. For example, people may not use motor boats or go fishing in the lakes, and they need official papers to drive there.

The word “low-carbon” sounds familiar to most of us. But do you know “low-carbon community (低碳社区)”? What is the community like? What benefits (好处) will it bring to our environment? Let’s have a look at Hanbei Road Community of Ya’an, Sichuan Province.
Walking into the community, people can see the hanging environmental slogans (环保标语) at first sight. And the most eye-catching items are idle bins (闲置物品投放箱) around. Many people in the community would give their idle things into the bins. Xu Juan, a mother of two, once put a pair of gloves there. “I think it’s meaningful to help others.”
In order to encourage more people to join in the “low-carbon” activity, the community introduced a reward program. Anyone can get some points if he/she gives idle things or takes part in volunteer activities. With certain points, people can exchange things in the “low-carbon supermarket” in the community.
There is also an “exchange corner” in the community. People can exchange their idle things (except the living things) with others. If he/she is not interested in any idle things in the corner, he/she can donate (捐赠) his/her things to poor families in the community.
“We are trying to make the best use of idle things by free exchange and donation. We hope all the people in our community can live low-carbon life,” said Wang Lu, leader of Hanbei Road Community.
1. What is Hanbei Road Community like?A.A community with many poor families. | B.A community with waste everywhere. |

8 . There are 8 billion humans on Earth. The sun is 150 million kilometers away. The universe (宇宙) may have 200 billion trillion (万亿) stars...
As scientists explore (探索) the world with more and more high-tech tools, the numbers that they use are also becoming bigger. Recently, scientists added four new names for numbers: ronna (1027), quetta (1030), ronto (10⁻27) and quecto (10⁻30).
Almost all human brains have a problem dealing with big numbers. In ancient times, early humans had no need to develop such a skill. They only needed to understand small numbers, like the number of people in the their family, or how many animals they had caught. So there’s no need to tell the difference between large and very large.
_______ One way is to turn big numbers into something you know. For example, if imagining 400, 000 people is too hard, you can think that a soccer playground usually can hold around 40, 000 people. Then 400, 000 people mean 10 soccer playgrounds of people. Or if you have 1,000 yuan, then a millionaire (百万富翁) has 1,000 times more money than you.
Although it is not necessary for us to understand larger numbers, we still can work out them and get useful answers.
1. What might one “quetta” refer to?A.One followed by 30 zeros. | B.A decimal point (小数点) followed by 26 zeros. |
C.One followed by 27 zeros. | D.A decimal point followed by 29 zeros. |
A.By telling about the Earth. | B.By showing some numbers. |
C.By telling a story. | D.By asking a question. |
A.However, how to tell the difference between them? |
B.However, how to deal with the differences? |
C.However, how big is a soccer playground? |
D.However, there are some ways to help us better understand big numbers. |
A.There were no large numbers in ancient times. |
B.Math is the best way for us to understand the world. |
C.Working out large numbers can help us deal with them. |
D.Human brains don’t have a problem dealing with large numbers |
Bats search for food in the dark using echolocation (回声定位), but that doesn’t mean that they can’t see, though they’re often wrongly thought to be blind. Research shows that many bats actually have good eyesight (视力) and use it to help them find food.
There are over 1,300 different kinds of bats in the world. Some feed on flowers, others on insects, and a few even feed on blood. Different kinds have developed different visual (视觉的) abilities. Many bats use both eyesight and echolocation when looking for food. Fruit bats, for example, don’t echolocate at all and actually have better eyesight than most humans. Even bats that eat insects prefer using eyesight when possible. Far from being useless, bats’ eyes are used to the dark environment to better help them look for small animals. Also, the eyes are improved by their great hearing power.
In a word, bats are not blind. They have different degrees of visual abilities and use them along echolocation to look for food. So now, being “as blind as a bat” doesn’t sound so bad, does it?
1. Which type of bat does NOT use echolocation?A.Fruit bats. | B.Blood-feeding bats. | C.Insect-eating bats. | D.Flower-feeding bats. |
A.Smell. | B.Eyesight. | C.Temperature. | D.Echolocation. |
A.There are about 1,200 kinds of bats. | B.All bats have the ability to echolocate. |
C.Some bats use eyesight and echolocation together. | D.Only fruit bats have good eyesight, while others do not. |
A.Why are Bats Special? | B.Are Bats Really Blind? |
C.What Great Powers Do Bats Have? | D.Are Men as blind as a bat? |
10 . Humans and dogs have been living and working together for thousands of years. Because of their protective (保护的) and playful nature, people often get dogs as pets for children. Today, because of their natural curiosity and excellent sense of smell, many dogs are being trained to help with different kinds of search and rescue (救援) jobs, for example, when a skier is lost in a snowy wilderness area or a child disappears in a forest.
The first known use of dogs to help rescue people took place in the Great St. Bernard Pass, a route (路线) in the mountains between Switzerland and Italy. There, hikers often became lost during bad winter weather. For many centuries, a group of monks (僧人) ran a small hotel there where travelers could spend the night. In the 17th century, the monks began taking dogs with them when they went out to rescue lost travelers. They knew the dogs could use their sense of smell to find people, but they soon discovered that the animals also had an excellent sense of direction, even when it was impossible to see anything through the heavy snow. Using dogs for search and rescue jobs became common during the First World War.
★ They have to go through strict training. The training can last up to two years, and trainers look for four qualities in the animals they choose: being able to communicate well with humans; focusing on one thing for a long time; enjoying playing games since the training includes doing the same thing over and over again; finally, it must follow orders all times or it might fight back. Dogs with these have become a valuable part of many life-saving teams around the world.
