Doctor Achebe: Today, we're exploring the impacts of children caring for pets. Some people believe that taking care of animals like dogs or cats can teach kids responsibility, empathy, and even improve their social skills. Can having a pet benefit children in their development? What do you think about the idea of kids raising pets? Share your thoughts on whether children benefit from caring for a pet and how this experience might influence their growth and development.
Andrew: I think children benefit from raising pets, fostering a sense of responsibility and empathy. Additionally, nurturing scientific curiosity is crucial for their development. Encouraging hands-on experiments and interactive learning in science enhances critical thinking and problem-solving skills. By combining pet care with scientific exploration, we can help kids develop a well-rounded set of skills.
Claire: I believe it's not beneficial for kids to raise pets as it's often the parents who end up caring for them. Children might lack the responsibility needed for proper pet care. Moreover, pets require consistent attention, which can be challenging for kids managing school and activities. This situation often results in parents taking on the primary caregiving role.

Other students think that the university should invite variety of guests speakers, regardless of their opinions. Which point of view do you support? Explain why.
Task2【重复20201014/ 20200910/ 20201015/20230514】 阅读：Online Office Hours 教授要把他的office hours改成允许学生通过在线视频进行答疑。 1. 对学生有益(Benefit Students)，因为学生可以从任何地方用电脑和她沟通，而不用 come to her office; 2. 因为不用待在 office里，所以可以 offer more opportunities to meet.
Task 3 【重复20230506】 阅读：Maladaptive Diffusion Older people are more likely to memorize positive experiences。 随着年龄增长，人的记忆会发生变化。尽管科研人员尚不清楚其中确切原因，但研究表明，随着年龄增长，老年人更关注获得正面奖励和评价，并且比年轻人更容易回忆起令人愉悦的时刻。 听力： 实验给20岁和70岁的人看两组图片，一组是愉悦的，一组是不愉悦的。要求他们尽可能多地记住这些图片，然后进行回忆测试。结果显示，相比年轻组，老年组记起更多快乐的瞬间，更容易回忆愉悦的场景和情境。
Task 4【重复20200813/ 20230118/ 20230401/ 20230506】 植物如何抵抗真菌的侵入（defenses plants develop to protect them from fungus attack） 1.External Defenses： 形成一种 physical layer，类似于waxy coating; 另一种，是通过释放种化学物质来阻止fungus蔓延。通过分泌物使真菌无法生长。例子是Tomato plant，番茄可以分泌一种阻止fungus蔓延的chemical。； 2. 通过部分坏死的方式阻止真菌延 (A part of plant dies off in order tostop the progression of the fungus.) 例子Barley Plant，当长fungus的时候，会自动杀死fungus周围的细胞，这样fungus无法获取nutrient就不能蔓延了。
2023.11.28线下阅读回忆 1. Dating Ancient Art (重复 10.29/9.16) 确定文物年代的传统方法是根据文物的粗糙程度来推断其年代，认为越古老的物品可能会更加粗糙。然而，这种方法并不准确，因为发现了很多古老但工艺精湛的文物，这挑战了以往的观念。 近年来，科学家们发现了一种通过探测生物体内放射性碳来推断其死亡日期的方法。这种放射性碳在生物体死亡后会逐渐分解，通过测量其分解程度，科学家可以计算出其死亡的时间。然而，这种方法只适用于有生命体的文物，对于矿物质或雕刻等无生命体的文物则不适用。因此，对于一些壁画等文物，科学家们只能通过探测其地质位置或者岩层来估算其年代。比如，通过岩层的高度变化来推测文物可能存在的时间跨度，以此来估算其大致的年代。 除了放射性碳和地质探测之外，科学家们还尝试通过探测周围环境条件来估算文物年代。例如，在干燥的沙漠地区，壁画可能会因为腐蚀而显示出更古老的迹象。而覆盖物也能提供一些线索，比如一个密封的巢穴或在壁画上的油漆和其他材料，可以提供有关文物年代的信息。
