③use cleaner energy: instead of coal and petroleum, governments should invest more in developing wind or water energy, thus less harmful gas will be produced
Task2 - When you study overseas, would you prefer to have roommate from your own country, or would you like to have foreign roommates?
Response tips:
Own country:
①similar living habits and customs: communication will be easier, roommates are more likely to support each other, might miss home less, adapt to foreign life quicker
②downside of foreign roommates: might have huge difference in culture, might won’t get enough help with English learning, roommates might party too much and influence normal living and rest
Foreign roommates:
①say you like meeting new people and have challenges: to explore foreign culture, to learn English faster or learn other languages, to build a wider social network
②downside of roommates coming from same country: lose chance to fully practice English, fell too relaxed and laid back... And based on experience for example Chinese roommates may end up playing computer games all the time and lose focus of overseas academic studying.
Task3
学生写信建议学校应该限制学生借阅图书的数量，因为很多学生借了大量的书没有用，并且不限制数量书籍容易被遗失。对话中女生反对。她指出大多学生参与很多课程，所以借阅数量超过10本非常正常，大多数人每本书会善用，而且大学生都是成人了不会一次性借太多书的;其次，她认为问题的关键不在于限制数量，而在于呼吁大家爱护书籍。

Task6
主题是product packaging的发展。第一个发展是新材料和技术的出现，比如曾经牛奶都是玻璃罐装的，昂贵且易碎，后来换成了塑料的节省了成本。第二个发展是包装变小，这样一来牛奶和其他小包装果汁软饮的竞争性就大了，因为它更具便携性。
