This allows you to feel they are safe.They can ring the emergency services if necessary. If your child is in immediate danger, they can use their phone to call not only you but the emergency services. This is of great benefit and could potentially save your childs life.Mobile phones can be turned off or on to silent. As long as your child remembers to do this their phone wont cause a distraction(分心) in class, but they will have a way to contact you if they need to. Giving them a standard rather than a smartphone will also reduce the risk of distraction.CONSThe latest smartphones can almost double as a computer .

Teams of researchers drove the turtles all the way from Massachusetts to Florida, where they were put back into the warm waters of the Atlantic Ocean.The turtles story began last fall, when a large number of them got stuck near Cape Cod in Massachusetts. These tough turtles had to be nursed back to good health for about six months before they could swim in the sea again.Sea turtles generally live south of the Carolinas in the Atlantic Ocean. But during the summer months, they take a ride on the Gulf Stream-a strong ocean current of warm water that runs north along the east coast. The Gulf Stream brings the turtles plenty of tasty food to eat.When summer turns to fall, sea turtles head south again as the water turns colder. Thats because sea turtles are cold-blooded. That means they cannot produce their own body heat. They need the seawater to provide them with heat.Some turtles dont get to warmer waters fast enough. When the waters of the northern Atlantic turn cold in the fall, many turtles cant stand the cold. They can not move and become unable to find their way. The turtles can drift only where the wind and tides take them.Many of these turtles are washed up on the shore near Cape Cod. Last year , 242turtles were rescued there.Scientists are unsure why so many needed to be helped. The turtles spent the winter getting better at aquariums along the east coast.As the weather grew warmer, 52 turtles were ready to return to their natural habitat. It was a great success for the turtles and the people who nursed them back to health.“Its an exciting day for all these organizations,” said Connie Merigo of the New England Aquarium.“This is what we work for. These are endangered species. So every turtle that gets back out in the wild and has a potential to contribute to the population is really important.” 4.How do the sea turtles come to the northern Atlantic? A.
