It seems that there's a good reason why dogs are always seen as man's best friend. Scientists have found that dogs are the only animals that can read emotion in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry. When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person's face first. A possible reason for this is that the right side of the human face is better at expressing emotions. Scientists have now shown that pet dogs also have "left gaze bias ", but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo showed 17 dogs pictures of human, dog and monkey faces as well as something else with his team. The dogs' eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs. Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions. "Recent studies show that the right side of our faces can express emotions better than the left. If true, then it makes sense for dogs and humans to see the right hand side of a face first." Why are dogs seen as man's best friend according to the passage? A) Because dogs are the closest animals to humans. B) Because dogs can read the emotions in humans' faces easily. C) Because dogs can understand us better when we feel sad. D) Because dogs are good at expressing emotions.

Ques: Like most cultures around the world, the Zulu people of Africa tell stories that have animals as heroes. These stories are meant to have fun, but they are also used to teach important lessons to children. This is one of those stories. One hot afternoon, Jackal was walking along the rocky road sniffing the ground. He was hoping to smell a mouse or a lizard , or something else that would be good to eat.

Help!" cried Jackal as he quickly jumped upon a large rock hanging over the road. "The rocks are falling down, and I can't hold them much longer. We shall both be crushed if you do not do your best to hold these rocks back, Lion" At once, Lion pushed his strong shoulder against the rocks to keep them from moving any further.

Everyone tries to get to school on time. But when bad weather gives you trouble, can you still make it before the bell rings? In northern China during spring, big sandstorms often make trouble for students and everyone else. When the sky is dark with sand, buses and cars all move much more slowly. Sometimes, people can't even see for 20 metres. Sandstorms usually happen in spring. This year, sandstorms started in late March. They have happened in more than 10 provinces in northern China this year. More than 70 million people have had problems in those places because of the sandstorms. People in southern China don't have to worry about this kind of bad weather. Most of the sand comes from Gansu and Inner Mongolia . In northern China, lots of places have few trees and don't get much rain. People there have been cutting down too many trees. When there aren't many trees, the ground can't keep enough water. Over the years, the ground dries up and turns to sand. When spring comes and the ice melts , the ground becomes looser . Strong winds take the loose sand into the sky. Sandstorms are bad for people's health. If people breathe too much sand, they could cough or have asthma . Sandstorms also give farmers lots of problems. Sometimes their sheep get lost in the storms and never get back home. The winds also tear down farmers' houses. What can you do to stop sandstorms? Here's an idea: Ask you parents to help you plant some trees this spring. If you see people cutting down too many trees, tell them about the dangers of sandstorms, and ask your government to stop them from cutting. Which is not stated in the passage? _ . A) Trees can help keep enough rain water B) More trees need to be planted C) Some people are doing harm to the environment D) Sandstorms are the main cause of asthma
