Moreover, part - time jobs may take up a lot of time, , like reading books or learning new skills. . But if a part - time job only aims at making money but sacrifices rest and growth, it's not worthwhile.然而，另一些人则持有相反的观点。让青少年在假期里没有时间休息或恢复精力在我看来，青少年在寒暑假期间是可以选择性地从事兼职工作的。Compose your writingNowadays, whether teenagers should take part - time jobs during school holidays has sparked a heated discussion.Many people believe it's beneficial for teenagers to do part - time jobs. Firstly, part - time jobs can help teenagers earn some pocket money, which allows them to learn how to manage money and reduces the financial burden on their families to some extent. Secondly, through part - time jobs, teenagers can come into contact with society earlier. They can improve their communication and teamwork skills, which is helpful for their future career development.Compose your writingHowever, others hold the opposite view. They think that some part - time jobs, such as manual labor, have little to do with teenagers' growth needs. Moreover, part - time jobs may take up a lot of time, leaving teenagers with no time to rest or recharge themselves during holidays, like reading books or learning new skills. In my opinion, teenagers can take part - time jobs selectively during school holidays. But if a part - time job only aims at making money but sacrifices rest and growth, it's not worthwhile.06HomeworkHomeworkPolish your writing第二课时Viewing Workshop Crazy Bridges For Animals Why did the chicken cross the road?

Can you come up with some other innovative ideas that may help animals cross the barriers?Animal - friendly tunnels with sensory guides: Tunnels that emit sounds or scents attractive to specific animals, guiding them safely through. For example, tunnels with a faint smell of certain plants that deer like.Floating pathways for aquatic animals: Floating structures in water bodies that crabs or small fish can use to move between habitats without being endangered by currents or human - made water barriers.Elevated rope bridges for arboreal animals: Strong rope bridges high up in trees, suitable for monkeys to swing and move across, connecting different forest areas.第三课时Reading Club 1 World Heritage Sites in ChinaWhat do you think a "World Heritage Site" might be?It might be a place with special cultural or natural value that is recognized by the world.Pre-Reading While-ReadingMatch the scenic spots with their corresponding descriptions or features1.The Temple and Mansion of Confucius2.The Old Town of Lijiang3.Jiuzhaigou Valley Scenic and Historic Interest AreaA.

Besides the three sites mentioned, think of one more World Heritage Site in China and explain why it deserves the title.The mountains, lakes, streams, trees, underground springs and waterfalls.Because there are narrow alleys, pretty streams, small stone bridges and houses with carved doors and painted windows, similar to the features of Venice.The Great Wall. It is a magnificent architectural wonder with a long history, playing an important role in ancient China's defense and witnessing significant historical events, so it has great cultural and historical value. 第三课时Reading Club 2 Natural is Turning on usGENERAL UNDERSTANDINGComplete the diagram with facts about natural disasters around the world.Natural DisastersEarthquakes: central Italy, in 2016Hurricanes and typhoonsReduced rainfallVolcanic eruptionsLandslides Asia, Europe and South AmericaUS, Central Americain Somalia and Kenya, in 2017; Canada in 2016Indonesia, in 2016; Mt Tambora, Indonesia, 1815Mocoa in Colombia, in 2017CRITICAL THINKINGAccording to the author, why is nature turning on us?First, overpopulation results in heavy building using local materials without proper planning, which can contribute to landslides or collapse during earthquakes. Next, global warming, caused by factories and vehicles, and the destruction of forests cause climate change and extreme weather conditions.CRITICAL THINKINGIs the author's attitude positive or negative towards the future? Find evidence from the text.The author has a negative point of view. He believes that environmental disasters will get worse, after speaking to experts. He says “Experts are predicting worse to come.”, “Most disaster experts believe that things could get a lot worse...”, “He warns that the world has not seen the worst yet...”, and “There are about two of these events every 100,000 years...”CRITICAL THINKING Do you agree with the author? Why? What is your attitude towards the future?I agree with the author that things will get worse. The writer presents a lot of facts of disasters in the text. In recent years there have been more natural disasters than in the past, so I think this will continue unless we can manage to stop or reverse global warming.THANK YOU
