Destruction of the world39。s rain forests is a severe problem. As part of a class project, Myers39。 students bought three acres （英畝） of rain forest in Central America. They paid $25 for each acre. The students hope that the land they bought will be protected and not destroyed. Last June, Myers and four of his students took a boat ride down a river. They saw alligators and crocodiles. In the middle of the week, a guide took Myers and his students into the rain forest. The monkeys were not happy that we were in their forest. They broke small branches off the trees and threw them at us, one of the students said. It was a great journey of exploring nature for all of us, said Myers. Each student close something special about Costa Rica to study involving the plants animals, food, and culture. During the last few days the group had time to do fun activation.

But these symbols will bee things of the past after 5G networks fully arrive. On March 30, Shanghai vicemayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also bee the first city in China to start testing 5G networks. About 100 times faster than 4G networks, 5G will let people download and upload data faster than ever before. But 5G won39。t just bring faster mobile Internet. People can use it to do many other things as well. For example, 5G will help to make selfdriving cars safer. Today39。s selfdriving test cars have one problemlag （延遲）. When the car sees an obstacle （障礙物）, it sends he information to a data center and receives instructions. However, it takes time to send and receive the information with this kind of lag, the cars might crash because they don39。t receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer according to CNN. 5G could also be used to power the Internet of Things （IoT）. This means a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. The IoT could be used in a lot of ways. For example, with IoT, your fridge could automatically （自動地） place an order online for eggs when it finds that there are no eggs left.（1）In which city was 5G tested for the first time in China? A.BeijingB.ShanghaiC.GuangzhouD.Shenzhen（2）The writer uses selfdriving cars as an example to ________. A.explain how selfdriving cars workB.tell us the possible d
