　　2017年7月2日

　　独立写作

　　【教育】/【多选一题型】 A city wants to help teachers of its high school students (age14-18)improve their teaching. It is considering two plans:

　　1. Choose a small group of excellent teachers; these teachers will attend a class led by an expert for additional training in how to teach effectively, and they will then come back to their schools and provide that training for other teachers in school.

　　2. Provide additional training in teaching effectively for high school teachers, using online material that each teacher will study individually.

　　综合写作

　　阅读：

　　淡水湖4千米冰层以下有larger，complex organism

　　1. VNP samples样本中可以看到很多这种larger，complex organism

　　2. 有能量来源，有Volcanic vents

　　3. 有发现Parasite bacteria暗示有宿主host存在，说明肯定有像fish oyster等complex organisms宿主的存在

　　听力：

　　这个说法skeptical

　　1. Sample可能会被contaminated，况且这个淡水湖外部就有很多这种complex organism 所以不能说明一定是来自这个湖的

　　2. 这种所谓的火山喷发提供能量不靠谱，因为这个lake跟Atlantic之间有ocean currents 所以后可能是大西洋洋流过去的

　　3. 寄生虫不一定非要依靠宿主，Parasite可以live independently 所以也无法说明这里有complex organisms
