Where Does a Can Go?
You finish a fizzy drink and drop the empty can into the recycling bin. That is not the end of the can's story. It is the start of a new one.
First, a truck collects the recycling and takes it to a sorting centre. There, machines separate the materials. A giant magnet pulls out steel cans. Aluminium cans (aluminum in the US) are not magnetic, so a different machine pushes them aside.
Next, the aluminium cans are squashed into huge blocks and taken to a factory. The cans are shredded into small pieces, cleaned, and melted in a furnace. The hot liquid metal is poured into moulds and cooled into long bars.
Then the bars are rolled out into thin sheets, like dough under a rolling pin. The sheets are cut and shaped into brand-new cans, filled with drinks, and sent to the shops. A recycled can can be back on a shelf in about sixty days.
Recycling aluminium is a big help to our planet. Making a can from old cans uses about 95 percent less energy than making one from new metal dug out of the ground. Aluminium can be recycled again and again without getting worse, so the can in your hand might once have been part of hundreds of other cans.

A Day at the Fire Station
Firefighters do much more than put out fires. At Station 9, the day begins at eight o'clock sharp with a check of every piece of equipment. The crew test the hoses, check the air tanks and make sure the ladders slide smoothly. "If something is broken, we need to know now, not when there's an emergency," says Captain Rivera.
After the checks, the firefighters exercise for an hour. Their job is very physical. They must carry heavy hoses, climb ladders in thick protective suits and sometimes carry people to safety.
In the afternoon, the crew often visit schools to teach children about fire safety. They show how to check smoke alarms and explain why you should never hide during a fire. "Get out, stay out, and call for help," Captain Rivera tells every class.
When the alarm rings, everything changes. The crew pull on their gear, jump into the fire engine and are on their way in less than a minute. Calls might be for a house fire, a car accident or even a cat stuck up a tree. Whatever the emergency, the firefighters of Station 9 are ready.
Question 2
Read "A Day at the Fire Station". What is the main idea of this text?
- A. Cats get stuck in trees.
- B. Fire engines are red.
- C. Smoke alarms need batteries.
- D. Firefighters have many different jobs during a day.
The Lemonade Stand
Marcus wanted a new bike helmet, but it cost twenty dollars. He had only five.
"Why not set up a lemonade stand?" suggested his grandmother. She helped him squeeze a big bowl of lemons and stir in sugar and cold water. Marcus painted a sign that said LEMONADE – 50 CENTS.
On Saturday morning, Marcus put his table at the end of the driveway. For the first hour, nobody came. Cars zoomed past. Marcus began to think it was a silly idea.
Then he noticed that people were walking to the park across the road for a football match. He picked up his sign and moved the table right next to the park gate. Within ten minutes, a line had formed. By lunchtime, the jug was empty.
Marcus counted his coins. He had earned exactly fifteen dollars. With the five he already had, it was enough.
"You did it!" said Grandma.
"We did it," said Marcus. "And next time, I'll think about where the customers are before I start."
Question 3
Read "The Lemonade Stand". Which sentence best sums up the story?
- A. Marcus earns money for a helmet by solving a problem with his lemonade stand.
- B. A football match is played in the park.
- C. Marcus and his grandmother make lemonade.
- D. Marcus paints a sign.
Inside a Volcano
Deep beneath our feet, the Earth is extremely hot – hot enough to melt rock. This melted rock is called magma. Because magma is lighter than the solid rock around it, it slowly rises upward. Sometimes it collects in a huge underground pool called a magma chamber.
A volcano forms where magma finds a way to the surface. When the pressure in the magma chamber becomes too great, the magma bursts out through cracks or vents. Once it reaches the surface, it is called lava. Over time, layers of cooled lava and ash can build up to form a mountain.
Most volcanoes are found near the edges of tectonic plates, the giant slabs of rock that make up the Earth's outer layer. More than half of the world's active volcanoes surround the Pacific Ocean, in a horseshoe-shaped zone known as the Ring of Fire.
Scientists sort volcanoes into three groups. Active volcanoes have erupted recently and could erupt again. Dormant volcanoes have not erupted for a very long time but might wake up in the future. Extinct volcanoes are not expected to erupt ever again.
Although eruptions can be deadly, volcanoes also bring benefits. Volcanic ash breaks down into rich soil, which is why many farms are found on the slopes of old volcanoes. In some countries, such as Iceland, the heat from underground is used to warm homes and produce electricity.
Question 4

- A. It argues that volcanoes should be studied more.
- B. It tells the story of a famous eruption.

- D. It explains how volcanoes form, where they are found, how they are classified and how they affect people.
Question 5

- A. Spiders are scary.

- C. Spiders are different from insects in several ways.
- D. Spiders have eight legs.
The Vault at the Top of the World
On a frozen island in the Arctic Ocean, between Norway and the North Pole, a narrow concrete doorway sticks out of the side of a mountain. Behind it, a tunnel leads deep into the rock. This is the Svalbard Global Seed Vault, and it holds more than a million packets of seeds from almost every country on Earth.
Why keep seeds in a mountain? Farmers all over the world depend on many different varieties of crops, such as types of rice that survive floods or kinds of wheat that resist disease. If a variety disappears because of war, natural disaster or simple accident, it may be lost for ever. The vault is a back-up copy, like saving a precious file in two places.
The location was chosen with care. The vault is high enough above sea level to stay dry even if ice caps melt. Inside, the seeds are kept at about minus 18 degrees Celsius, cold enough to keep many of them alive for decades or even centuries. The surrounding rock is permanently frozen, so even if the power failed, the seeds would stay cold.
The vault opened in 2008. In 2015, it was used for the first time: scientists who had lost access to their own seed bank during a war in Syria withdrew samples, grew new plants and later sent fresh seeds back to the vault. The back-up had worked.
No one hopes the vault will be needed often. But like a fire extinguisher in a school corridor, it is reassuring to know it is there.
Question 6

- A. Norway is a cold country.
- B. The seed vault protects copies of crop seeds in case they are lost elsewhere.

- D. Wheat is better than rice.
The Fennec Fox
The fennec fox is the smallest fox in the world. It weighs about as much as a bag of sugar. It lives in the Sahara Desert in North Africa, one of the hottest places on Earth.
The first thing most people notice about the fennec fox is its enormous ears. They can be as long as 15 centimetres, which is huge for such a small animal. The ears do two important jobs. First, they let heat escape from the fox's body, helping it to stay cool. Second, they are so sensitive that the fox can hear insects moving under the sand.
The fennec fox has other ways to survive in the desert, too. Thick fur on the bottoms of its feet protects it from the burning sand. During the hottest part of the day, it rests in a cool burrow underground. It comes out to hunt at night, when the air is cooler.
Water is hard to find in the desert, but the fennec fox can go a long time without drinking. It gets most of the water it needs from the food it eats, such as insects, plants and small animals.
Question 7
Read "The Fennec Fox". What is the main idea of the whole text?
- A. The Sahara is very hot.
- B. Foxes eat insects.
- C. The fennec fox has special features that help it survive in the desert.
- D. The fennec fox is the size of a bag of sugar.
