Reading comprehension lesson 10: Nature and science facts · Set 42 · 12 questions

Reading tip (Find the key word): Pick the key word in the question (roots, honey, clouds). Find that word in the passage. Read that sentence carefully — it holds the answer.

1. 1.Ants are tiny insects, but they are very strong. An ant can carry things much heavier than its own body. Ants live together in large groups called colonies. Some ants build their homes under the ground, with many rooms and tunnels. When an ant finds food, it leaves a smell trail. Other ants follow this trail to reach the food.
   
   How do other ants reach the food? (a) They ask a bird (b) They fly there (c) They follow the trail (d) They dig a hole
2. 2.Trees are very useful to us. They give us fruits, wood and shade. Trees take in the air we breathe out and give out oxygen, the gas we need to live. Their roots hold the soil together, so it is not washed away by rain. Birds build nests in trees, and many insects live on them. That is why we should plant more trees and not cut them down.
   
   Which gas do trees give out? (a) dust (b) steam (c) smoke (d) oxygen
3. 3.The Sun is a star, the closest one to Earth. It is a huge ball of very hot gases. The Sun gives us light and heat. Without the Sun, there would be no plants, animals or people on Earth. The Sun looks small only because it is very far away. We must never look straight at the Sun, because it can hurt our eyes.
   
   Why must we never look straight at the Sun? (a) It moves fast (b) It is too far (c) It can hurt our eyes (d) It is rude
4. 4.Elephants are the largest animals that live on land. An elephant uses its long trunk to breathe, smell, drink and pick up food. It sucks water into its trunk and then sprays it into its mouth. Elephants have big ears that flap to keep them cool. They live in groups led by the oldest female. In India, elephants live in forests in Kerala, Karnataka, Assam and other states.
   
   Who leads a group of elephants? (a) the biggest male (b) the youngest calf (c) a tiger (d) the oldest female
5. 5.Butterflies begin their life as tiny eggs on leaves. A caterpillar hatches from each egg. The caterpillar eats leaves all day and grows bigger and bigger. Then it makes a hard case around itself called a pupa. Inside the pupa, the caterpillar slowly changes. After some days, a beautiful butterfly comes out and flies away.
   
   Which is the correct order? (a) egg, caterpillar, pupa (b) caterpillar, egg, pupa (c) egg, pupa, caterpillar (d) pupa, egg, caterpillar
6. 6.Winds are moving air. A gentle wind is called a breeze, and it feels pleasant on a hot day. A very strong wind with heavy rain is called a storm. A cyclone is a huge storm that forms over the sea and can damage houses and trees. Before a cyclone, the weather office warns people near the coast. People then move to safe places until the cyclone passes.
   
   What does “gentle” mean in the passage? (a) soft and mild (b) very loud (c) very cold (d) very strong
7. 7.Plants make their own food in their leaves. To do this, they need sunlight, water and air. The roots take in water from the soil. The green colour in the leaves helps them catch sunlight. Animals cannot make their own food like plants do. That is why plants are very important for all living things.
   
   True or false: Animals can make their own food like plants. (a) False (b) True
8. 8.Butterflies begin their life as tiny eggs on leaves. A caterpillar hatches from each egg. The caterpillar eats leaves all day and grows bigger and bigger. Then it makes a hard case around itself called a pupa. Inside the pupa, the caterpillar slowly changes. After some days, a beautiful butterfly comes out and flies away.
   
   What does the caterpillar eat? (a) seeds (b) leaves (c) insects (d) flowers
9. 9.Water can be found in three forms. When water freezes, it becomes solid ice. When ice melts, it turns back into liquid water. When water is heated, it turns into steam, which is a gas. We use ice to keep drinks cold on hot days. Clouds are formed when water vapour cools high up in the sky.
   
   What does water become when it freezes? (a) steam (b) rain (c) clouds (d) ice
10. 10.The Sun is a star, the closest one to Earth. It is a huge ball of very hot gases. The Sun gives us light and heat. Without the Sun, there would be no plants, animals or people on Earth. The Sun looks small only because it is very far away. We must never look straight at the Sun, because it can hurt our eyes.
    
    Why does the Sun look small? (a) it is behind clouds (b) it is cold (c) it is very far away (d) it is tiny
11. 11.Frogs can live both in water and on land. A frog lays its eggs in water. Tadpoles come out of the eggs and swim with their tails, like tiny fish. Slowly, they grow legs and lose their tails. Then they hop out of the water as young frogs. Frogs catch insects with their long, sticky tongues. In the monsoon, you can hear them croaking loudly.
    
    What do frogs use to catch insects? (a) webbed feet (b) long, sticky tongues (c) their tails (d) their back legs
12. 12.Elephants are the largest animals that live on land. An elephant uses its long trunk to breathe, smell, drink and pick up food. It sucks water into its trunk and then sprays it into its mouth. Elephants have big ears that flap to keep them cool. They live in groups led by the oldest female. In India, elephants live in forests in Kerala, Karnataka, Assam and other states.
    
    Which are the largest animals that live on land? (a) giraffes (b) camels (c) rhinos (d) elephants
