29、of experiences.【语篇解读】本文是一篇说明文。文章提出了五个应对和缓解焦虑的建议。1G设空处前句“These arent anxiety cures.”告诉我们吃好睡好并不是治愈焦虑的方法，因为焦虑更大程度上是一种精神方面的问题，而G项“Anxiety is more of a mental health disorder developed through years of experiences.”是对前句的解释，符合上下文语境。2E本段的建议是“练习瑜伽”，E项“It is a slower form of exercise that is not challenging.

30、”正是对瑜伽的说明，与本段主题一致。3F设空处前句“Flying your imagination is a great one.”建议我们通过放飞想象力来有效缓解我们的焦虑。结合选项可知，F项符合上下文语境。4A本段第二句“So stop focusing on those thoughts and give yourself a break to simply calm down.”告诉我们不要把注意力集中在那些想法上，让自己休息并平静下来。也就是说让自己的注意力分散，不要考虑让人焦虑的事情。故A项符合上下文语境。5D空前句提到把你的想法写在日记里，看起来就像是你小时候才做的事情，而下文的“It not only gives you a chance to let out your thoughts，but tells your brain that it doesnt have to focus on remembering them as much as it did previously.”则具体讲了写日记的好处。前后存在转折关系，故D项(然而它是一种强有力的治愈工具)与语境吻合。
