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.The Moon is Earth’s closest neighbour in space. It does not make its own light. The Moon shines because sunlight falls on it and bounces off. As the Moon goes around Earth, we see different shapes of it. On a full moon night, we see the whole round Moon. On a new moon night, we cannot see the Moon at all. It takes about a month for the Moon to go around Earth.
   
   On which night can we not see the Moon at all? (a) every night (b) a full moon night (c) a festival night (d) a new moon night
2. 2.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
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 often should we brush our teeth? (a) twice a day (b) once a week (c) once a day (d) five times a day
4. 4.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.
   
   How do tadpoles swim? (a) with fins (b) with their tongues (c) with their tails (d) with their legs
5. 5.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) Rain washes soil (c) Birds build nests (d) Trees are very useful
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.
   
   Why must we never look straight at the Sun? (a) It moves fast (b) It is rude (c) It is too far (d) It can hurt our eyes
7. 7.Our heart is a strong muscle about the size of our fist. It works like a pump and pushes blood all around the body. The heart never stops, even when we are asleep. Blood carries food and oxygen to every part of the body. When we run or play, our heart beats faster. Doctors listen to the heartbeat with a stethoscope.
   
   What do doctors use to listen to the heartbeat? (a) a mirror (b) a thermometer (c) a stethoscope (d) a torch
8. 8.Our eyes help us see colours, shapes and light. Our ears help us hear sounds. We smell with our nose and taste with our tongue. Our skin helps us feel if something is hot, cold, rough or smooth. These five are called our sense organs. We must take care of them, for example, by not reading in dim light.
   
   Which organ tells us if something is rough? (a) eyes (b) nose (c) ears (d) skin
9. 9.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 dig a hole (b) They follow the trail (c) They fly there (d) They ask a bird
10. 10.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.

    What is the camel called? (a) the desert horse (b) the ship of the desert (c) the king of the jungle (d) the sand king

    What does a camel’s hump store? (a) fat (b) milk (c) water (d) sand
12. 12.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 is the hard case around the caterpillar called? (a) a shell (b) a nest (c) a hive (d) a pupa
