9、rds. In the 2nd century BCE, in the Han Dynasty, the Changan-Tianshan Corridor began to develop. The network remained in use until the 16th century, after experiencing a gradual expansion between the 6th and 14th centuries. At first, silk was the main item exported by China on the Silk Road, and the
10、n exports gradually included china and tea. Horses, wool, cotton and grapes were imported along the network. The network also served as a bridge for cultural exchange. Astronomy and mathematics were introduced to China, and so was Buddhism. Important Chinese inventions reached the West through the n
11、etwork. Through these routes, Eastern and Western civilizations were connected. Today, such exchanges are continuing with the Belt and Road Initiative. Overall, the Silk Road is a crucial part of humanitys common heritage.【设计意图：本课一个重要的技能学习：写课文总结，先带领学生观看选必三第二单元第六课微课How to write a summary，然后根据教材指导学生写本

13、e, in Kenya, China helped build the countrys Standard Gauge Railway (SGR). This development is one of the most significant projects in Kenya since it became independent in 1963. The SGR facilitates local industries, as well as trade between Africa and China. Energy is another way the initiative has
14、impacted countries along its path. A hydropower station project in Pakistan was approved and operated by a Chinese company. After its completion, it will generate enough electric power to provide for the Pakistani peoples daily use and also assist in the nations economic development. The initiative
15、also promotes trade between the countries on its routes. For example, Kazakhstan, a landlocked country, struggles to grow vegetables because of its very cold weather. The Belt helps enhance cooperation between Kazakhstan and the north-western Chinese Xinjiang Uygur Autonomous Region. They are thus a

The trade between Xinjiang and Kazakhstan not only provides the Kazakhs with their basic needs, but also generates mutual economic benefits for both the countries.【设计意图：通过丝绸之路经济带的讨论，一方面帮助学生深入理解课文最后两段，也有助于学生走出课文，形成自己的观点和看法。此项活动也有助学生灵活运用语言来表

33、ient GreeceAncient Greece is the cradle of Western civilization, and the Acropolis perhaps the most famous of all landmarks from that era. Widely regarded as the symbol of ancient Greek culture, the Acropolis is one of the most outstanding and complete ancient architectural complexes that still exis
34、t today. The Greek government appointed a committee in 1975 to undertake a complete restoration of the Acropolis and it was declared a UNESCO World Heritage Site in 1987. The Acropolis is a large flat rock in the centre of Athens, rising up high above the city. Since it is easy to defend, it was use
35、d as a fort from the 13th century BCE onwards. In the 5th century BCE, the greatest Greek architects and artists of the time began building temples on the rock. They used marble, a type of very smooth, strong stone. However, marble does not last forever. The stone can be worn down by natural forces,
36、 and human activities are also a main cause of damage. Firstly, since it served as a fort, the Acropolis suffered damage in countless wars. Secondly, millions of travellers who visit each year have also harmed the buildings, simply because so many people walk through them. Finally, Athens has some of the most polluted air in the world, and acid rain is gradually wearing down the marble of the Acropolis. The Acropolis is a gift to future generations. It has stood the test of time and will continue to serve as a reminder of the rich history of Greece.
