Everymorning before class, they raced each other around the track, pushing their limits. Bala always tried to startfaster, while Ahmad focused on his breathing.Friday arrived. The entire class gathered at the track to cheer them up. When warming up near the startline, Bala said jokingly, “"Ready to lose, Ahmad. I will beat you this time." Ahmad responded with just ameaningful smile and then concentrated on his own stretches." Get set.. Go!" The gun went off. Bala started very fast and took the lead right away, Ahmadfollowing him closely. At the first turn, Bala started to get tired from running too fast.

Theyofficially made their first appearance in World War II when they were used to locate humans trapped underrubble piles after bombings. These well-trained dog heroes were able to find victims much faster thanhuman search teams, making them incredibly valuable tools when time was important to the survival oftrapped individuals. Since then, these amazing dogs have been used in natural disasters because they canThe science behind how dogs find lost humans is complex. However, we can understand it by learninghow their olfaction works. Dogs are born to smell things. Almost one-third of their brain is used to handleall the smells they detect. 'They have a highly developed sense of smell that allows them to separate mixedsmells and focus on just one smell at a time. They can also tell where a smell is coming from by using eachnostril independently, and they can recognize different smellsUrban disaster rescue dogs work using a method called air scenting. It requires dogs to search a largearea for the purpose of locating specific, condensed human smell coming from under the rubble. Therefore,the dogs’ natural hunting ability must be focused on human smell, whether the person is alive or dead. To高一英语学科 试题 第4页 (共9页)
