1、判断题:
以下说法正确吗。Q1:摩擦表面的纳米结构对TENG表面电荷密度有什么影响?A1:我们最早是使用两种不同材质的平坦的表面,但是当它们真正接触时,看起来平坦的面在原子层面上并非如此。而只有当它们的距离小于一定数值时才会发生电荷的转移,因此只有很少一部分的接触面上进行了电荷的转移,这表明宏观平坦的摩擦表面效果并不好。而如果使用具有金字塔结构的摩擦面,则可以让输出功率增加20倍。所以说将其中一个摩擦表面进行微纳结构加工,不仅能增加接触面积,也能增加两个面之间的电荷转移量。但是如果两个面都是粗糙的,则会降低发电机的性能,这说明表面过于粗糙是对发电机不利的因素。所以在进行表面纳米结构加工时要控制粗糙的程度,从而得到最佳的性能。 ( )

1、 材料:
Sarah is 36 years old, and she lives in Canada. She has two young daughters. She works two days a week as a teacher. Her husband’s name is Nathan, and he’s a sales manager. Nathan’s job is very busy, so he often comes home late. At weekends, they often go driving or walking in the countryside.
Nathan was born in Canada, but Sarah wasn’t. She was born in Argentina, and she moved to Canada when she was 26. When she was growing up, she was really interested in English. At first, she thought it was difficult, but when she finished school she could already speak quite fluently, and understand almost everything she heard or read. She spent a lot of time listening to songs and watching TV shows and films in English.
After she graduated from university, she decided to train as an English teacher. The certificate she needed was quite expensive, and competition for places was intense, but she was determined to do it—she simply couldn’t imagine doing anything else. She finished the course with a distinction, which was the highest grade possible. Soon, she found work as a teaching assistant in a local primary school. She enjoyed the work, although it was often challenging—the children were not always well-disciplined, and she didn’t think that the classroom teacher had enough understanding of teaching methods.
When she first went to Canada, she never would have imagined that she would end up staying there. It was supposed to be a short-term placement in a high school. She thought that she would be able to see a different part of the world and gain some useful experience, which could help her to find a better teaching position when she came back to Argentina. At first, she found living overseas much more difficult than she had expected. She felt homesick, and she had problems getting used to everything which was different in Canada—the interpersonal culture, the climate, the food… For the first three months she was there, she spent most of her free time in her room, dreaming of going back to Argentina and seeing her family again.
Over time, she adjusted to life in Canada, and even started to enjoy herself a bit more. One day, she met Nathan at a party. She liked his sense of humour, and how kind he was, but she was reluctant to get involved, knowing that she was planning to leave in the near future. When her placement finished, he convinced her to apply for a permanent job in another school. She told herself that she would give it one more year and see how things went.
Now, Sarah is settled, although she still misses Argentina. She tries to make it back at least yearly, and she is bringing up her daughters to be bilingual, so that they can talk to their Argentinian relatives in Spanish. When she thinks back to her first few months in Canada, she can scarcely recognise herself. In some ways, she wishes she weren’t so far away from her family, but at the same time, she feels that she’s learned many things which she never would have experienced had she stayed in Argentina. She wants to give her daughters the chance to travel and experience life in other countries as soon as she can, although of course she hopes they don’t move too far away!
