August is one of the most popular months to travel for Chinese. Choosing the perfect destination for an August vacation isn't easy. We looked at airfare trends, climate data, and cultural calendars to select 4 vacation spots that are some of the best places to visit this August.

Mackinac Island, Michigan

Visitors can enjoy the sunny weather while boating, fishing, and sailing. On land, you can hop between historic sites like Fort Mackinac and Fort Holmes, both key sites in the War of 1812.

And sweet teeth will have something to celebrate too: the Fudge（软糖）Festival, which takes place every August and allows the many fudge shops on the island to show off their best work.

Martha's Vineyard, Massachusetts

Martha's Vineyard is praised as one of the most classic summer getaways in the United States.

The charming island south of Cape Cod is dotted with simple and elegant New England homes, relaxing sandy beaches. The sunny summer weather in August sets the perfect stage for a boat outing or a shopping trip to the town's shops of all kinds.

Krakow, Poland

Krakow, Poland, is the perfect mixture of history and nightlife.

Tourist favorites in Krakow include Wawel Cathedral, St. Mary's Basilica, and the Schindler's Factory museum, each of which gives a glance into Poland's religious and political history. After the sun sets, enjoy Krakow's world——famous bar and restaurant scene, and don't forget to pop into a cafe for a late-night snack.

Every year, one of the grandest wonders in nature is performed here—the Great Migration.

There has been a lot of publicity recently surrounding 5G, the next generation of wireless technology for the world. But what is this technology and how might it change our lives?

5G stands for fifth generation, meaning the next step in the progression of technology to replace the current 4G system. 4G was the replacement for 3G, which came after 2G, and so on. Earlier "G" systems were designed to improve mobile communication operations. Each new technology brought major improvements in speed and greatly increased network capacity（容量）. The new 5G system promises more of the same. However, technology experts say there is a major way that 5G is different than the earlier systems. It will move well beyond mobile network technology to affect many more devices and industries than other "G" versions.

Wireless industry groups say 5G will help fuel future "smart cities" by connecting sensor（传感器）networks. 5G is also expected to connect self-driving cars and support new technologies involving virtual reality. Higher 5G speeds could also permit doctors to commonly perform remote medical operations. Factories and businesses could use 5G technology to increase automation and improve the collection of information.

Every coin has two sides.Much of the data could contain private details about individuals, businesses or government organizations. The increased data flow would give internet attackers a lot more possibilities to steal and misuse data. In addition, the wider use of a 5G wireless network means any breakdown of the system would have more widespread and severe results. Such difficulties could affect public safety as well as world economic activity.

24. What is the significant difference between 5G and the early “G” systems?

A. It will affect more devices and industries.

B. It will change the way people communicate.

C. It will reform the pattern of information system.

D. It will improve internet speed and network capacity.

25.What can we learn about "smart cities" from the passage?

A. Smart city is a city full of intelligent people.

B.Now many smart cities have been built all over the world.

C. As long as there is a wireless network, you can build a smart city.

D. The development of 5G accelerates the construction of smart cities.

26.Why can 5G allow doctors to perform long-range medical operations?

A. Because of the low cost of 5G.

B. Because of the wide range of 5G.

C. Because of the high speed of 5G.

D. Because of the ability of 5G to collect information.

27.What is the last paragraph mainly about?

A. Possible risks of 5G technology.

B. The advantages of 5G technology.

C. The influence of 5G technology on the world.
