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.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.
   
   What is the main idea of the passage? (a) Insects are small (b) Birds build nests (c) Rain washes soil (d) Trees are very useful
2. 2.Honeybees live together in a home called a hive. A hive has one queen bee, who lays all the eggs. The worker bees collect nectar from flowers and turn it into honey. They also clean the hive and look after the young bees. When a bee finds flowers, it does a special dance to tell the others where to go. Bees also help plants by carrying pollen from flower to flower.
   
   What do worker bees collect from flowers? (a) seeds (b) nectar (c) leaves (d) water
3. 3.Our teeth help us bite and chew food. Children have twenty milk teeth, which fall out one by one. New, stronger teeth grow in their place. Sugary food and sticky sweets can cause holes in our teeth. So we should brush our teeth twice a day, in the morning and at night. We should also rinse our mouth with water after every meal.
   
   How many milk teeth do children have? (a) thirty (b) sixteen (c) ten (d) twenty
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 youngest calf (b) the biggest male (c) a tiger (d) the oldest female
5. 5.The camel is called the ship of the desert. It can walk for many days on hot sand without drinking water. Its long eyelashes protect its eyes from blowing sand. Its wide, flat feet do not sink into the sand. The hump on its back stores fat, not water. In India, camels are found in the deserts of Rajasthan.
   
   What does a camel’s hump store? (a) sand (b) fat (c) milk (d) water
6. 6.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.
   
   What is the Sun made of? (a) ice (b) water (c) very hot gases (d) rocks
7. 7.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 of these do trees give us? (a) metal (b) plastic (c) shade (d) glass
8. 8.Rain begins with the Sun heating water in seas, rivers and lakes. The warm water turns into water vapour and rises into the sky. High up, the air is cold, so the vapour cools and forms tiny drops. Many drops join together to make clouds. When the drops become too heavy, they fall as rain. This journey of water is called the water cycle.
   
   What is this journey of water called? (a) the rain dance (b) the cloud trip (c) the water cycle (d) the river path
9. 9.The camel is called the ship of the desert. It can walk for many days on hot sand without drinking water. Its long eyelashes protect its eyes from blowing sand. Its wide, flat feet do not sink into the sand. The hump on its back stores fat, not water. In India, camels are found in the deserts of Rajasthan.
   
   What is the camel called? (a) the ship of the desert (b) the sand king (c) the king of the jungle (d) the desert horse
10. 10.Our teeth help us bite and chew food. Children have twenty milk teeth, which fall out one by one. New, stronger teeth grow in their place.

    What can cause holes in our teeth? (a) fresh water (b) sticky sweets (c) green leaves (d) brushing
11. 11.Rain begins with the Sun heating water in seas, rivers and lakes. The warm water turns into water vapour and rises into the sky.

This journey of water is called the water cycle.
    
    True or false: The air high up in the sky is cold. (a) False (b) True
12. 12.Magnets can pull things made of iron and steel. This pull is called attraction. A magnet cannot pull wood, paper, plastic or glass. Every magnet has two ends called poles: a north pole and a south pole. Two north poles push each other away. A north pole and a south pole pull each other close. Magnets are used in toys, fridge doors and compasses.
    
    What can magnets pull? (a) wood and paper (b) plastic and glass (c) iron and steel (d) stone and sand
