Jill Robbins: 修复杂草丛生的花园需要系统性的规划与操作。首先,建议在秋冬季节进行规划,通过记录和观察花园的每一部分,决定哪些植物可以保留、哪些需要移除或特别照顾。清除死植物、杂草和入侵植物是首要任务,尽量在天气允许时挖除它们的根系。对于健康的植物,可以通过在线社区或邻里网页找到愿意接收的人。如果花园植物过于茂密,可能需要使用电锯或重型机械。对于杂草较多或需要新建花床的区域,可以通过覆盖植被而非挖掘来处理,使用纸板或报纸覆盖,并添加堆肥和覆盖物。修剪是恢复灌木健康的关键,尤其是落叶灌木,最佳修剪时间是在冬季末。土壤的pH值测试和改良也是重要步骤,确保土壤适合新植物的生长。最后,选择不易过度生长的树木、灌木或多年生植物进行种植,并覆盖地面以防止杂草生长和土壤干燥。

Key Insights

What are the key steps to repair an overgrown garden?

To repair an overgrown garden, start by assessing the garden and making a list of plants to save, remove, or tend to. Remove dead plants, weeds, and invasive species, preferably in autumn or spring. Give away healthy plants you don’t want through online groups. For dense vegetation, use tools like chainsaws. Cover areas with cardboard, compost, and mulch to suppress weeds. Prune deciduous shrubs in late winter and test soil pH before planting. Finally, choose native plants and ground cover to prevent weeds and soil drying.

What were the major technology developments in 2024?

In 2024, major tech developments included advancements in AI, such as Microsoft’s personal AI agents and Apple’s AI-equipped iPhones. Researchers used AI to improve weather prediction models. California banned AI-generated deepfakes in elections. Google faced legal action for monopolistic practices, and TikTok contested a U.S. law requiring its sale. Aurora Innovation launched driverless trucks, and the FAA finalized rules for air taxis, marking a new category of aircraft.

What are the risks associated with New Year’s resolutions?

New Year’s resolutions can involve risks when they involve significant life changes, such as moving to a new city, starting a new job, or ending a relationship. These decisions carry consequences if things don’t work out. However, taking such risks can also lead to positive outcomes, as expressed in the phrases 'nothing ventured, nothing gained' and 'fortune favors the bold.'

How does word stress improve clarity in spoken English?

Word stress involves emphasizing certain words by saying them louder and longer, which helps make sentences clearer. For example, stressing verbs like 'am,' 'is,' or 'are' can highlight their importance. Native speakers often use stress to emphasize key points, such as in the sentence 'It is beautiful.' This technique is especially useful for learners to improve comprehension and pronunciation.

What is the significance of the FAA’s new rules for air taxis?

The FAA’s new rules for air taxis, classified as Advanced Air Mobility (AAM) flyers, mark the first new category of aircraft in nearly 80 years. These rules set training and approval requirements for pilots and pave the way for widespread AAM operations in the U.S. Air taxis operate on electrical power with vertical takeoff and landing capabilities, representing a significant advancement in transportation technology.
