话题：湿地植物cypress trees的根有一部分露在地表，被称为knees，讨论它的作用

阅读：

1. absorb oxygen 吸收氧气；

2.保持树的稳定，使树不被风或水等破坏；

3. release methane 排出甲烷

听力一一反驳：

1. 根据科学家的实验，把knees放在装满氧气的容器(container)里经过一段时间后，氧气含量(content of oxygen)并没有变化，说明knees不是用来吸收氧气的

2. 用来保持树的稳定的根是垂直(vertical)的，而knees长在水平(horizontal)的根上，因此不具备保持稳定的功能(additional stability)；

3. 甲烷对植物虽然没有好处但并没有坏处，所以树没必要进化出一种feature去release这种没影响的气体；另外，树根上有许多微生物(tiny organisms)也可以排出甲烷，并不需要knees排出甲烷。

This week, we discussed the importance of role models and opinion makers in society. One idea we discussed was the widespread impact of "influencers." Influencers are people who are very active posting on social media and who have many followers. Influencers' posts and opinions can influence their followers' choices on everything from fashion to politics. In your opinion, do social media influencers generally have a positive or negative effect on their followers? Why do you think so?

Kelly 

I think the influencers' effect is generally positive. People can learn about the latest trends and topics in a very quick and efficient way by following influencers. In the past, people had to spend time looking through magazines or visiting boutiques to even know what was trending.

Paul

I think influencers generally have a negative effect because they have far too much influence. I can think of one influencer who only has to mention a particular kind of sports shoe, and the next day they'll be sold out. The followers aren't really thinking for themselves; they're just blindly following the influencers' choices.

Why young animals play阅读提出了三个原因:

1.利用多余的能量（surplus energy）

2.生存训练（instinct-practice theory )，为以后捕猎（prey）做准备，例子是狼

3.培养社会关系（develop social bond with other members），例子是老鼠（rats）

听力一一反驳：

1.海洋生物小海豹（marine animal young seals）在等妈妈带食物回来前没有多少能量也会玩耍

2.试验人员（researchers）做了实验，分两组cats，一组小时候训练狩猎游戏（hunt play），另一组不训练，结果长大后能力并没有什么区别

3.观察表明老鼠在过了玩耍的年龄后，还可以培养社会关系（develop social relationship），所以这个能力并不是玩耍培养的

This week, we will be discussing space exploration. Some people think that it is a waste of money for governments to fund space exploration. Others disagree with this view arguing that space exploration is a valuable and necessary investment for our future. They think that it is worthy for governments to fund space exploration. I want to know what you think about this topic. Do you think that governments should fund space exploration? Why or why not?

Kelly

I don't think that governments should fund space exploration because it will be too costly to build spaceships and develop related technologies. Though space exploration tech costs billions, it doesn't offer direct benefits to most people, which makes its funding a controversial issue.

Andrew

Personally, I do think that all the costs will be worth it. The potential scientific discoveries and technological advancements could have far-reaching impacts that justify the initial investment. Imagine the new inventions that might come from this exploration. Such technology could greatly improve our everyday lives.

金星上出现ashen light现象的三个原因。

 阅读 ——

1. 紫外线的照射使氧原子变成氧分子，这个过程会产生黄光；

2. 闪电和暴风雨造成的；

3. 望远镜的问题造成的幻像。           

 听力 ——

1. 出现的是绿光，不是黄光;

2. 闪电常常发生在白天，晚上很少出现，但是黄光是在晚上出现的；

3. 观察者在不同的地方并且用不同机器都看到并且记录下来了，所以不是幻像。

Dr. Achebe：

We've been discussing the idea that human well-being is notnecessarily improved by ever-increasing production andconsumption of goods and services. Some people argue that humans already consume too many goods, from clothing to electronics to food: they believe that excessive consumption has created serious problems for humanity andeven the planet. Do you agree that excessive consumption-buying more than we truly need has become a serious problem? Why or why not?

Kelly: 

I absolutely agree. We buy far more than we need, and that can't continue indefinitely. For years people haveused shopping as a form of recreation. The products bought on a whim are filling up landfills, and the energy expended producing the goods has created a global warming crisis. We should start gradually reducing consumption.

Andrew: 

I disagree with the idea that overconsumption is a dramatic problem. l agree there is some overconsumption, but it happens mostly with wealthy people. l think in general almost everyone else already buys only what they need. In fact, many people around the world are not even able to obtain everything they need.
