Reading comprehension lesson 10: Nature and science facts · Set 183 · 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.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.
   
   Where does a cyclone form? (a) in the hills (b) in a forest (c) over a desert (d) over the sea
2. 2.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.
   
   Why do elephants flap their big ears? (a) to hear better (b) to scare birds (c) to keep them cool (d) to fly
3. 3.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.
   
   What do we see on a full moon night? (a) a thin Moon (b) half the Moon (c) the whole round Moon (d) no Moon
4. 4.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 protects a camel’s eyes from sand? (a) its long neck (b) its hump (c) long eyelashes (d) its wide feet
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) Birds build nests (b) Rain washes soil (c) Trees are very useful (d) Insects are small
6. 6.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.
   
   Where are butterfly eggs laid? (a) in nests (b) in water (c) under stones (d) on leaves
7. 7.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 river path (b) the cloud trip (c) the rain dance (d) the water cycle
8. 8.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
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 king of the jungle (b) the desert horse (c) the sand king (d) the ship of the desert
10. 10.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.
    
    Who builds nests in trees? (a) fish (b) cows (c) frogs (d) birds
11. 11.A seed has a baby plant inside it. When a seed gets water, air and warmth, it starts to grow. This is called germination. First, a tiny root grows down into the soil. Then a small shoot grows up towards the light. Soon the first green leaves open. You can watch this happen by keeping a few moong seeds on wet cotton.
    
    What grows first from the seed? (a) a tiny root (b) a flower (c) a shoot (d) a leaf
12. 12.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 cools high up in the sky to form clouds? (a) dust (b) ice (c) water vapour (d) smoke
