独立口语

Task 1：

Some people think that, when moving to a new country, they should adapt to the cultural habits and traditions of the new country. Other people prefer to keep their original habits and traditions. Which point of view do you agree with? Explain why, using details and examples in your response.（搬到一个新的国家的时候，有的人认为应该去适应当地的新的文化和习惯。而有的人认为应该保留原来自己国家的文化和习惯。你支持哪一个观点？）

综合口语

Task 2：

It is very common to see students sleeping on the couches in the library. I do not think the university should allow this, for two reasons. First, when students sleep in the library, they occupy spaces where other students need to sit in order to get their work done. Second, when visitors come to our university and take a campus tour, the tour always takes them into the library. If these visitors see students sleeping there, they will get the impression that students at our university are not serious about their studies.

Question：The man expresses his opinion about the proposal described in the letter. Briefly summarize the proposal. Then state the man's opinion about the proposal and explain the reasons he gives for holding that opinion.

学生写信建议学校应该禁止学生在圈书馆睡觉，因为一方面当有学生想学习的时候，有可能这个地方己经被睡觉的学生给占了，那么想学习的学生就学不到了。第2个原因是经常有家长会来参观学校，而图书馆是非常重要的一个参观点。当家长来参观的时候，如果看到有学生睡觉的话，家长会觉得这些学生不认真学习。

听力：不支持阅读的观点，因为其实他们去图书馆自习的时候，总是能找到学习的地方。因为睡觉的人往往都会去找柔软的沙发，而书桌井不适合睡觉，因此那些书桌需要学习的地方总是有空间的。而且来参观的家长也都能够理解学生，家长会觉得学习的学生哪怕已经因了也不回寝室，而是小睡一下，马上就继续投入学习，所以家长觉得学生还挺爱学习的。

Task 3：

Many companies restrict access to the designs of their products in order to protect them from their competitors, so that those competitors do not copy their products Sometimes, however, companies may encourage all interested people to access and modify their designs, even if these people are from a competing company. This model of development, known as open source development, allows companies to work together cooperatively to improve products. This model can be beneficial when products require new technology that is expensive and complex, since companies can share costs and work together to find solutions to problems in order to create successful products.

Explain how the example from the professor's lecture illustrates the concept of open source development.

有些公司在开发产品的时候，会把产品进行完全的保密，用于防止竟争对手来抄袭。但是有些公司在开发的时候喜欢用开源的模式，哪怕是竞争对手，也欢迎来访问，欢迎大家共同来开发这个产品。当需要开发的产品，庞大而且很昂贵的时候，这个模式会更好。

听力：例子讲的是一家电车公司，公司在刚刚成立的时候全都是自主进行研发，但是。汽车的价格特别高，使得汽车的销量也不好，而且研发的成本也非常高。因为他们希望开发的是电池体积很小，但是储存电量特别大的这种电池。他们很快就耗光了所有的经费。这样的电车公司就接近于失败了。还有另外一家电车公司，他把自己的整个研发的内容全都向同行业来进行开源，最终使得电池的成本非常的低廉，而且其他的同行也都跟进，也都采用他们的电池，因此就使得价格很低,销量也非常的高。

As countries work to reduce emissions and protect the environment, many governments are encouraging the adoption of electric vehicles through new policies. This week we will discuss ideas for policies that could promote electric vehicle usage. In your post, I would like you to address this question: What policies should the government implement to promote electric

vehicles for environmental protection?

Andrew

More charging stations are key to getting people to buy electric cars.

It's frustrating when you can't charge your car. The government should offer big tax credits to businesses to build charging stations. If charging spots are everywhere, range anxiety will go away and electric car sales will take off. We need that to help the Earth.

Claire

The government needs to create entire highways just for electric cars. These special roads could have charging stations along the way so range anxiety disappears.

Exclusive electric highways would show electric cars are the transportation of the future. We'd see tons more Teslas on the road helping clear the air.
