The giraffe is smaller than the blue whale but it is also a record breaker. It's the tallest living land animal. It's got the longest neck-about 2 metres long, and it's got the longest legs-about 1.8 metres long. Drinking is difficult, but eating from the top of trees is easy! And its tongue is 50 c m long!

① Do you have a dog? What can your dog do for you? Do you know that dogs can read our feelings? Now some people find that dogs can smell (v.闻到; n.嗅觉) people's stress (压力).

②Dogs really are man's best friends. They have special smell. A new study said that dogs can smell if people are feeling stressed. Teachers at Queen's University, UK, made the study. They got breath(呼吸)and sweat(汗) from people both before and after doing a hard maths problem. They looked at the people's heart rate (心率), blood pressure (血压) and stress feeling in the study. Dogs can smell the difference in breath and sweat from people. Then they can know when people are stressed.

③The finding is wonderful: the dogs found stress in 675 of the 720 people. It could be 93.75% right! Australian News reported. The study's writer Clara Wilson said, "stress can change people's breath and sweat. Dogs are very good at smelling these changes." In the study, she also said, "this finding helps us learn that how dogs may know people's feelings."

④ This finding shows how special the bond is between people and dogs. The finding also tells us that dogs are very clever. And maybe dogs can help stressed people.
