【题目】简要概括原初引力波的发现是“里程碑式的重大成果”的依据。

科学家宣布首次观测到宇宙原初引力波存在的证据,若获证实,这将是里程碑式的重大成果。广义相对论预言了宇宙诞生之初产生的原初引力波的存在,这一发现有力地佐证了广义相对论。引力波可以作为光观测以外另一种观测宇宙的手段,由此打开了引力波天文学的大门。现在关于大爆炸原初时刻的理论模型有数百个,原初引力波忠实记录了暴涨时期的物理过程,如果观测结果是真的,那么很多理论模型会被排除。宇宙微波背景辐射是宇宙大爆炸的“余烬”,多年来人们一直没有测量到引力波的独特印记——B模式偏振,新发现无疑将进一步增强人们关注与研究的力度。

答:________________________________________________________________________

________________________________________________________________________

【答案】能佐证广义相对论。可以作为观测宇宙的新手段。排除很多理论模型。促进宇宙微波背景辐射的测量。

【解析】题目要求概括原初引力波的发现是“里程碑式的重大成果”的依据,文段是总分式结构,从“这一发现有力地佐证了广义相对论”“引力波可以作为光观测以外另一种观测宇宙的手段”“如果观测结果是真的,那么很多理论模型会被排除”等中可提炼出答案

【题目】阅读下面的文字完成各题。

我接到一个不认识的朋友的来信,他说愿意跟我去死。这样的信我已经接过好几封了,都是一些不认识的年轻人寄来的。现在我住在一个朋友的家里,是一个很安静的地方。我的窗前种了不少的龙头花和五色杜鹃,在自己搭架的竹篱上缠绕着牵牛花和美国豆的长藤。在七月的大清早,空气清新,花开得正繁,露出一片欣欣向荣的景象。对面屋脊上站着许多麻雀,它们正吵闹地欢迎新生的太阳。到处都充满着生命。我的心也因为这生命的繁荣而快活地颤动了。

然而这封信使我想起了另一些事情。我的心渐渐地忧郁起来。眼前生命的繁荣仿佛成了一个幻景,不再像是真实的东西了。我似乎看见了另一些景象。

我应该比谁都更了解自己罢。那么为什么我会叫人生出跟我去死的念头呢?难道我就不曾给谁展示过生命的美丽么?为什么在这个充满了生命的夏天的早晨我会读到这样的信呢?

我的心里怀着一个愿望,这是没有人知道的:我愿每个人都有住房,每个口都有饱饭,每个心都得到温暖。我想揩干每个人的眼泪,不再让任何人拉掉别人的一根头发。

然而这一切到了我的笔下都变成另一种意义了。我的美丽的愿望都给现实生活摧毁干净了。同时另一种思想慢慢地在我的脑子里生长起来,甚至违背了我的意志。

我能够做什么呢?

我就是真理,我就是大道,我就是生命。能够说这样话的人是有福的了。

我要给你们以晨星!能够说这样话的人也是有福的了。

但是我,什么时候才能够说一句这样的话呢?

一九三四年七月在北平

【题目】 What makes a gift special? Is it the price you see on the gift receipt? Or is it the look on the recipient's face when they receive it that determines the true value? What gift is worth the most?

This Christmas I was debating what to give my father. My dad is a hard person to buy for because he never wants anything. I pulled out my phone to read a text message from my mom saying that we were leaving for Christmas shopping for him when I came across a message on my phone that I had locked. The message was from my father. My eyes fell on a photo of a flower taken in Wyoming. and underneath a poem by William Blake. The flower, a lone dandelion standing against the bright blue sky, inspired me. My dad had been reciting those words to me since I was a kid. That may even be the reason why I love writing. I decided that those words would be my gift to my father.

I called back. I told my mom to go without me and that I already created my gift. I sent the photo of the cream-colored flower to my computer and typed the poem on top of it. As I was arranging the details another poem came to mind. The poem was written by Edgar Allan Poe; my dad recited it as much as he did the other. I typed that out as well and searched online for a background to the words of it. The poem was focused around dreamin, and after searching I found the perfect picture. The image was painted with blues and greens and purples, twisting together to create the theme and wonder of a dream. As I watched both poems passing through the printer, the white paper coloring with words that shaped my childhood. I felt that this was a gift that my father would truly appreciate.

Christmas soon arrived. The minute I saw the look on my dad's face as he unwrapped those swirling black letters carefully placed in a cheap frame, I knew I had given the perfect gift.
