Both globes and maps help you find where the places are．Both show you the size and shape of the places， too． But maps are flat pictures． Often， they show just a part of the earth． Globes are round like balls． They are models of the earth． They show the whole planet． Maps are light and easy to carry． Globes are heavier and harder to manage． They usually stay in one place． Maps and globes both show directions and distance.

Mercury and Venus are closer to the sun than the earth． However， Mercury is 36 million miles away from the sun． Venus is 67 million miles away． It takes Mercury 88 days to orbit（沿轨道运行）the sun． Venus spends about 230 days orbiting once around the sun．Venus is about the same size as the earth． Mercury is much smaller． Both Mercury and Venus get very hot．Scientists do not think there is life on either planet．

As dolphins and porpoises（鼠海豚）are very similar， people often cannot tell the differences between them． Both dolphins and porpoises are mammals like lions and whales． They can be seen in the oceans， seas and rivers．They are so intelligent that they have the ability to think， understand， and learn things quickly and well． They have large，complex brains．They make sound waves to help them know things well and find their ways in the water．Dolphins and porpoises feed on fish． The main difference is that dolphins like talking a lot and love to communicate with people as they are together．They make whistling sounds through their blowholes to communicate with one another． Porpoises are usually timid and shy．
