Not only will this be the only full supermoon of 2017,____it's also going to kick off a series of three full supermoons in a row. The full moons on Jan. 2 and Jan. 31 will be super ____(one) and even they'll be blue super moons,____means the second full moon in a single month.

    While some moonwatchers might be getting excited, some people think the hype（炒作）around supermoons isn't all it ____ (regard) as being. A scientist slammed（抨击）the term last year as something made up ____ (complete) and a waste of everyone's time.

    If the supermoon makes you want to go out and appreciate the sky's beauty, we say “Go for it.”

材料一：（宋代理学大厦的创建）不是偶然的。宋代经济、文化、科学相当发达。有学者统计，宋代士人在全部人口中占有一定比例，通过科举而做官的不少。……历经元、明两朝，理学逐渐失去活力，而朱熹《四书集注》成为学人取得功名利禄的敲门砖。这种思想呆滞局面，由于明、清朝代的交替而引起学人们的思考。由明到清这样的“变局”应当由谁来负责？以往的思想文化有什么误区？中国传统思想中的儒、道和其他学派应如何评价？应怎样估量佛教的传入等等重要思想理论问题，让人不得不去研究、思考，并提出应有的答案。

材料二：基于历史，******指出，创新是一个民族进步的灵魂，是一个国家兴旺发达的不竭源泉。也是中华民族最鲜明的民族禀赋。我们的先人不仅早就有“苟日新，日日新，又日新”等创新理念，而且发明了造纸术、火药、印刷术、指南针，创造了天文、算学、医学、农学等多个领域的累累硕果。……立足当代，******肯定新中国成立以来我国科技事业取得的科技成就，但也正视我国科技创新基础还不牢、自主创新特别是原创力还不强、关键领域核心技术受制于人的格局没有从根本上改变的客观现实，力倡创新发展。

——2016******创新思想的三个“支撑点”

①世界上的事物是瞬息万变，无法捉摸的

②事物都是不断运动变化的，不运动的事物是不存在的

③事物的联系是有条件的，相对的

④一切以时间、地点、条件为转移

已知甲物体在光滑的水平面上运动，乙物体在粗糙的水平面上运动，现用相同的水平推力分别使甲、乙两个物体沿力的方向移动相同的距离，两次推力所做的功分别是W_甲，W_乙，则W_{甲 ____}W_乙．

    From a young age, I've had a really deep connection with being outside. I've been skiing since I was eight or nine years old. I've been on expeditions(探险)in many places like China, Pakistan and so on. But it was in my home country, the USA, that I came closest to death.

    It was Apri1 1, 2011. I was skiing in the Tetons with my friends Jeremy and Xavier, both experienced snowboarders. That day, I was the last person to ski. They were watching me from a safe area. Suddenly, I heard someone cry loudly I turned around and saw the whole mountain start to move behind me. It was a massive avalanche(大雪崩). The kind of avalanche that destroys trees, cars, buses, even houses! Tens of thousands of tons of snow were coming straight down the mountain behind me. I felt the snow push me forward, hundreds of meters, and then cover me. It was so heavy that I couldn't breathe. And then it pushed me forward again and up, out of the snowpack. I looked around, and for a few seconds I actually stopped being terrified. I had a moment to pause and to look at the power of the avalanche.

    I looked down into the bottom of the valley(峡谷). I could see trees that were 30m tall because I was so far away, they looked tiny to me.“OK, I' m going all the way to the bottom!” I thought. Then the snow pushed me again down the mountain another 450m I thought the force of the Snow would destroy me, it was powerful. But in the end, I felt the avalanche slow down and I just popped (迸出)right out of the snow at the bottom of the valley.

    It took Jeremy and Xavier about 20 minutes to reach me. There was a pile of debris(碎片)across the bottom of the mountain 300m wide. They couldn't believe it when they saw me. I was so lucky.

    Has the experience changed me? Do I think about life differently? I don't know, maybe. But I don't know that it's important to live your life with meaning. Life is a gift, so use it wisely.
