1.听写包 答案：

And as for the bananas, researchers also found a high percentage of fossils from banana plants in sediment samples dating from about 7,000 years ago,

proof the bananas were deliberately planted, because where bananas grow naturally the concentration of the plant fossils is lower.
Bananas don’t naturally grow so densely.
As a matter of fact, recent genetic research, genetic comparisons of banana species,
suggests that the type of banana grown in New Guinea was domesticated there and then brought to Southeast Asia.
So, not sure where I’m going with this?
Well, usually, we expect to see that certain social changes are brought about by the development of agriculture,
structural changes in the society like rapid population growth, different social classes.
But New Guinea, it’s largely unchanged.
It’s remained an egalitarian and rural society, so what does that tell us about the usual assumption?
至于香蕉，研究人员还在距今7000年前的泥沙样本中发现了很集中的香蕉植物化石，
证明香蕉是被故意种植的，因为在香蕉自然生长的地方，植物化石的集中率较低。
香蕉不会自然生长得那么密集。
事实上，最近的基因研究，对香蕉品种的基因对比，
发现生长在新几内亚的香蕉的品种是在那里驯化的，然后才被带到了东南亚。
不知道我要用这个表达什么？
通常，我们期望看到某些社会变化是由农业的发展引起的，
社会中的结构变化，比如人口快速增长，出现不同的社会阶级。
但是新几内亚很大程度上保持了不变。
它仍是一个平等的田园社会，那关于平常的设想，这又告诉了我们什么呢？

2.阅读包答案：

因此，我们可以得出，图画想要表达的含义是， 缺乏环境保护意识的游人通过乱扔大量垃圾给旅游景点的生态平衡造成了威胁。

3.写作包答案：

As a traditional Chinese calculation tool and an important ancient Chinese invention,the abacus was widely used before the invention of Arabic numerals in the world. The abacus is a rectangle with a wooden frame. Within the frame,rods with stringed beads are fixed. The beam in the middle of the frame divides each rod into two parts. The two counting beads in the upper part of each rod represent five and the rest five beads in the lower part represent one. With the application of the abacus, people summarized many calculation tips to help improve the speed of calculation. As the abacus is simple to produce, and its calculation tips are easy to memorize and operate, it is quite popular in China.
