(2019·贵阳监测)Nov. 21 is World Hello Day. It began back in the an effort to make the world more peaceful. It was created just after the Israel and Egypt in 1973. The philosophy (哲学) behind it is：Say stop war.
It sounds like a fine idea, but most of us know that simply saying won’t bring about world peace. Still, on a smaller range, the simple act of to someone can make a lot of difference.
This might not be obvious. After all, it’s such a casual thing and requires so little effort. You raise your head to someone as you pass by them in the school corridor(走廊), say “Hello”， and then it’s over.
Although we might not realize it, a small thing like a greeting can mean a lot to a person. Many people are lonely because they’re shy. They find it difficult to communicate with people, even though they want to. It leads to them feeling cut off.
On this basis, maybe it’s a good idea, not just on Nov. 21, but every day, to remember to say “Hello” to as many people as we can. The stranger who hears your greeting may secretly smile in their heart. You might even make their day.
Greeting other people is the easiest way to be polite．Politeness is the way we individual humans link up with the rest of the human world outside of our circles of family and friends. Politeness is one of the aspects of culture that make us a society rather than just many individuals living in the same space.
No one said it better than the French author Joseph Joubert：“Politeness is the flower of humanity．” A “Hello” to a stranger is a small thing, and often neglected(忽视), but through it we can make the world better for another person.

(2019·长沙名校第二阶段测评)Scientists found gravitational watched the effects of two black holes running into each other and bigger one, a century after Albert Einstein predicted that such an event ripples(波纹) through space-time.
Scientists “heard” the wave with the help of laser beams(激光束) sent through two pipes which form an angle of 90° between each other and are nearly 2，000 miles apart in the U.S. That equipment let them glimpse the nature of black holes．Together they made up the Laser Interferometer Gravitational-Wave Observatory (LIGO).
Gravitational waves were first observed in September 2015 and the second detection(发现) occurred three months later. The third detection, which the astronomers called GW170104, was made on January 4, 2017. The astronomers believed their latest finding “provides clues about the directions in which the black holes are spinning”.
“Black holes are beautifully simple. You just need two numbers to describe them completely: mass, how much they bend space-time, and a spin, how much space-time moves about them，” said Dr. Christopher Berry of the University of Birmingham, one of the researchers in the project. “But it takes lots of hard work to measure these from our data. We now have wonderful mass measurements, and are starting to uncover details about the spins of these black holes, which could give evidence for how they formed．” The researchers said their discovery added further evidence to support Einstein’s general theory of relativity and confirmed the existence of previously unknown black holes.
More than 1, 000 scientists from the LIGO Scientific Collaboration were involved in the project along with an additional 280 researchers from the European-based Virgo Collaboration. Scientists hope gravitational waves will offer a completely different view of the universe, allowing them to study events that might be hidden from traditional

telescopes. “We have further confirmation of the existence of stellar(恒星的)-mass black holes that are larger than 20 solar masses. We didn’t know they existed before LIGO detected them，” MIT researcher David Shoemaker said.
【解题导语】 本文是一篇科普说明文。科学家们第三次探测到引力波，相对论再获证实，促进了黑洞研究。
5．Who pioneered gravitational waves? A．David Shoemaker． C．Scientists from LIGO.
B．Christopher Berry. D．Albert Einstein.
D 解析：细节理解题。根据第一段中的“a century after Albert Einstein predicted that such an event would send ripples(波纹) through space-time”可知， 科学家们的这一发现发生在爱因斯坦预测此事件的一个世纪后，因此爱因斯坦是引力波的先行者。
6．How did scientists discover gravitational waves? A．By using laser beams. B．By joining vertical pipes. C．By using traditional telescopes. D．By following the orbit of black holes.
A 解析：细节理解题。根据第二段第一句“Scientists ‘heard’ the wave with the help of laser beams(激光束) sent through two pipes which form an angle of 90° between each other and are nearly 2，000 miles apart in the U．S．”可知， 科学家们是通过使用激光束来探测到引力波的。
7．What can we learn from the last three paragraphs? A．More than 2，000 scientists took part in the event. B．Scientists have already discovered spins of black holes. C．Gravitational waves contributed to black holes’ research. D．There is no way to find out how black holes are formed.
C 解析：推理判断题。根据第三段中的“The astronomers believed their latest finding ‘provides clues about the directions in which the black holes are spinning’．”和第四段中的“We...are starting to uncover details about the spins of these black holes, which could give evidence for how they formed．”可知， 科学家们第三次发现引力波给黑洞的旋转方向提供了线索， 黑洞的旋转细节可能为它们的形成方式提供证据。即引力波对黑洞的研究有作用。故选C。
8．What do the scientists think of the application of gravitational waves? A．It’s controversial. C．It’s limited.
B. It’s promising. D. It’s demanding.
B 解析：观点态度题。根据最后一段中的“Scientists hope gravitational waves will offer a completely different view of the universe, allowing them to study events that might be hidden from traditional telescopes．”可知， 科学家们希望引力波会提供一个完全不同的宇宙观，使得他们能研究使用传统望远镜可能发现不了的事情， 即他们认为引力波的运用很有前景。故选B。

Ⅱ 七选五
(2019·成都毕业班摸底测试)Everyone dreams．If you’ve ever tried to figure out the meaning of a strange dream, you’re not alone．Humans have been trying to make sense of dreams since recorded history．1．________ Here are some of the findings.
2．________People with great creativity are more likely to dream about unusual settings and about blocks in the natural world, such as a log or a rock they can’t get around.
You’ve got a heart problem. People who have frequent nightmares may be significantly more likely to suffer from an irregular heartbeat or chest pain. If you have those problems，it’s more difficult for you to breathe at night．3．________
You’re avoiding something. Do you dream about being followed by a stranger, a monster, or a giant tidal wave? This could indicate that you’re afraid to deal with something in your daily life. 4．________
You’ll have a good result in a test. Students whose performance improved were those who had dreamed about the maze(迷宫) during the sleep. 5．________This improves learning and problem-solving skills.

(2019·合肥高三调研)Our class organized visit to the Joy Nursing Home, that is next to our school, last Sunday. On our arrival, we begin to help the senior people do the cleaning. After that, some of my classmate put on interesting performances, but then we played games with them. All of them were amusing and laughed happily. We were such lost in the activities that we forgot the time. At noon, we were all had to say goodbye to them. And they were extreme grateful to us for their visit.

①organized后加a。考查冠词。visit是可数名词，在此处表示泛指且visit的发音以辅音音素开头，故用不定冠词a。
②that改为which。考查定语从句。分析句子结构可知，应用which引导非限制性定语从句，在从句中作主语，修饰先行词the Joy Nursing Home，表示物的概念。
③begin改为began。考查动词的时态。由上文中的last Sunday可知， 事情发生在过去，故用一般过去时。
④classmate改为classmates。考查名词单复数。由句中的some of my可知， 此处表示复数的概念， 故用classmates。
⑤but改为and。考查连词。根据语境可知， 此处前后为逻辑上的顺承关系， 而非转折关系， 故用连词and。
⑥amusing改为amused。考查形容词。amused意为“感到有趣的”， 一般形容人， 而amusing意为“逗人发笑的”， 一般修饰物。故把amusing改为amused。
⑦such改为so。考查副词。so/such...that...意为“如此……以至于……”， so修饰形容词、副词或者动词， 而such修饰名词。 此处修饰lost, 故用副词so。
⑧删除were。考查动词的语态。 根据语境可知， 本句已有谓语动词had, 且表示主动语态， 而非被动语态， 故删除were。
⑨extreme改为extremely。考查副词。 修饰形容词的词一般为副词， 故用副词extremely修饰形容词grateful, 在句中作状语。
⑩their改为our。考查代词。由句中的us可知， 此处表示“我们的”， 故应用形容词性物主代词our
