How will you celebrate New Year’s Eve? By having a party with your classmates? Going to the karaoke for a singing competition? Many people around the world celebrate the day. Let’s have a look at what people in other countries do.
In the United States, thousands of people jam into Times Square in New York to welcome in the new year at midnight. The change from New Year’s Eve and New Year’s Day is very exciting. People count down the seconds to welcome the new day as the New Year ball slowly gets down and lights up the area.
In Spain, when the clock strikes midnight, everyone eats 12 grapes. They eat one grape for each toll (钟声) to bring good luck for the next 12 months of the new year.
In Scotland, fireworks are set off in front of the Edinburgh Castle. Immediately after midnight, people sing Auld Lang Syne. The words are in Scottish and mean “days gone by”. The famous Scottish poet Robert Burns wrote the song.
In Brazil, most people wear white clothes on New Year’s Eve to bring good luck for the new year. If they live near a beach, after midnight, people go there, light candles in the sand, throw flowers in the sea and make a wish. They say that the goddess who protects the sea will make their wishes come true.
Did you know?

There is a lot of talk these days about how kids should be interested in science.
Here’s an area of science for everyone, and these cool new books might inspire you to discover your inner scientist.
Scaly Spotted Feathered Frilled by Catherine Thimmesh, 58 pages, ages 9-12
Seeing a picture or a model of a dinosaur, do you wonder how anybody knows what they look like? After all, nobody has seen a living dinosaur. This book explains how scientists and artists work together to re-create dinosaurs. As scientific discoveries have been made, the models have changed. Scientific tests may one day expose what a dinosaur’s coloring was, but now artists have to use their imagination to determine how these huge creatures looked.
Beyond the Solar System by Mary Kay Carson, 128 pages, ages 10-13
This book takes readers back to the beginnings of space exploration—thousands of years ago, when people began star observation—and forward to today’s search for planets in distant parts of the Milky Way. Along with history lessons, readers get 21 activities, such as making a black hole and creating a model of Albert Einstein’s universe using a T-shirt. The activities are perfect for cold winter days.
Ultimate Bugopedia by Darlyne Murawski and Nancy Honovich, 272 pages, ages 7 and older
If you’re always on the lookout for butterflies, this book is for you. Hundreds of color photos of common and unusual insects fill this hardcover. There are fascinating stories related to the photos. For example, do you know an insect feeds on the tears of Asian cattle? There’s a question-and-answer section with an insect scientist and advice on how to help preserve endangered insects.
Journey Into the Invisible by Christine Schlitt, 80 pages, ages 9-12
If you use a magnifying（放大的）glass, you know a leaf looks quite different. This book explains what microscopes do and then shows what happens to things around the house when watched with this amazing scientific tool.

The man who admitted to killing an Italian woman inside her East Harlem apartment said he was possessed by an “evil spell (咒语),” police said Thursday.
Bakary Camara, 41, who once dated the murdered woman, penned his admission of guilt in a three-page letter folded in his pocket as he tried to kill himself after policemen burst into his home. Kelly, a policeman, said “He says that there was an evil spell that was cast on him.”
Camara, who was in stable condition at St. Barnabas Hospital, was later charged with the murder of Rita Morelli.
The 36-year-old woman was getting a degree at Borough of Manhattan Community College as she waited tables at Caffe Buon Gusto on the upper East Side, police said. Camara called 911 from a payphone after killing the lively Morelli on Nov. 23. Her body was later found in her E. 120th St. home. She was hanged and had knife wounds to her throat and chest.
Policemen began dialing numbers f rom Morelli’s cell phone and when Camara picked up, a detective recognized his voice as the man who called in the report of a dead body, police said. When officers went to Camara’s home, he locked himself inside, forcing policemen to burst down the front door to catch him.
“He is standing there with a knife pointed at his chest,” Kelly, a policeman, said. “He makes threatening statements as to the fact that he killed the woman. He then stabs himself in the chest.”
Camara, who told police he served six years in prison for robbery back in his native country, was still waiting to be charged with murder Thursday.
Morelli left her hometown of Spoltore, Italy, five years ago to fully experience the arts and music culture of the big city, her family said.
8. The reason why Camara killed the woman was _______.
A. he didn’t love her any more
B. the passage didn’t tell us clearly
C. he killed her by mistake
D. he loved her dearly
9. Which of the following is true according to the passage?
A. Morelli and Camara are both Italians.
B. Camara will be sentenced to six years in prison.
C. Camara was once in prison for six years.
D. Camara was seriously wounded.
10. From the passage we know ______.
A. Camara was in his native country
B. “Evil spell” really works
C. Camara and Morelli are husband and wife
D. Camara and Morelli knew each other
11. What did Camara do after killing the woman?
A. He called to report a dead body.
B. He called the hospital to save the woman.
C. He regretted and tried to kill himself but failed.
D. He called the police and was ready to be arrested.
D
Driving a car is not just handling controls and judging speed and distance. It requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant (抑制药), damaging eyesight, judgment and co-ordination(协调), slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.
Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.
The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is:
● 50 milligrams of alcohol per 100ml of blood; or
● 22 micrograms of alcohol per 100ml of breath; or
● 67 milligrams of alcohol per 100ml of urine (尿液).
Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.
Any drive found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK $25,000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence points; or temporarily banned from driving.
The same punishment applies to failing to provide specimens (样本) far breath, blood or urine tests without good excuse.
Drink driving is a criminal offence. Be a responsible driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.
12. The first paragraph is mainly about ________.
A. the introduction of driving skills
B. the damage of drinking to your body
C. the effect of drinking on driving
D. the process of alcohol being absorbed
13. The unde rlined word “it” in the second paragraph refers to “________”.
A. alcohol
B. absorption
C. blood
D. process
14. Which of the following is TRUE according to the passage?
A. Drinking below the drink driving limit has no effect on driving.
B. Alcohol is taken in more quickly when drunk with fruit juice.
C. Having a cup of tea helps to get rid of alcohol from the body.
D. 50 milligrams of alcohol per 100ml of breath is below the drink limit.
15. A drive suspected of drink driving ________.
A. should provide specimens for testing
B. will be forbidden to drive for 3years
C. will be punished for 10 driving-offence points
D. should pay a maximum fine of HK $25,000

Flash Mob: The Pop Culture
If you see a group of people dancing and singing on the street or in the railway station, you don’t need to feel surprised. They are a flash mob. Who are they? Are they mobs (暴民)? 16 Actually, a flash mob is a group of people who gather suddenly in a public place, do something unusual for a brief period of time, and then quickly separate.
A flash mob is usually organized with the help of the Internet or other digital communications networks. 17 At a predetermined time, they gather and perform some tasks such as exchanging books, coming together to look at the sky, waving their hands and yelling something at the top of their lungs for 30 seconds. Then, they quickly disappear before the police can arrive.
Bill Wasik, senior editor of Harper’s Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob gathered on June 3, 2003 at Macy’s department store. More than one hun dred people stepped onto the ninth floor carpet department of Macy’s department store, gathering around an expensive carpet. Following this flash mob, about 200 people flooded the lounge of the Hyatt hotel and applauded for about fifteen seconds. 18
Flash mob gatherings can sometimes shock people. Such an activity might seem amusing, but it might also frighten people who are not aware of what is taking place.
19 They also have enormous economic potential, such as using flash mobs to advertise
a product.
20 People use it to do many things. For example, in 2009, Michael Jackson’s fans took part in a flash mob to remember him. Hundreds of his fans gathered outside the railway station in Liverpool. They were singing and dancing Michael’s famous song “Beat It” together. And in another example, some people took part in a flash mob to tell more people not to use negative words.
Flash mobs give people from all walks of life an opportunity to come together to create a memory.
A. Don’t be confused by their name.
B. People are attracted by the silly and harmless activities.
C. The flash mob is now becoming more and more popular.
D. Using mobile phones, the flash mob can change their gathering place.
E. A later mob saw hundreds of people in Central Park making bird noises.
F. The messages may be forwarded to friends, who forward to more people.
G. Undoubtedly, flash mobs can serve as good political tools in any direction. 第二部分英语知识运用（共两节，满分45分）

Dear schoolmates,
Good evening! As I am graduating, I’d like to look back on my unforgettable years here.
In the p ast three years, I’ve benefited a lot from my school education, which helps me grow into an independent thinker and an efficient learner. However, I was too concerned about my study to get actively involved in the extra-curriculum activities.
Looking ahead, I think the biggest challenge in my college life will be adapting to a life away from my parents and taking care of myself. But I’m full of confidence that I’ll get used to it soon.
I also want to make some suggestions to you, my dear schoolmates. Time and tide wait for no man. We teenagers should make the most of our valuable time at high school and realize our full potential.
Good luck to all of you!

甘肃省天水市第一中学2018届高三第一次模拟考试 语文试题 学校_________ 班级__________ 姓名__________ 学号__________ 一、现代文阅读 1. 阅读下面的文字，完成下列小题。 康德认为，认识含有感性、知性和理性三个要素。感性是接受印象的能力，知性是规则的能力，理性是原理的能力，它们一起构成人类认识的完整结构。康德的这一划分，揭示了认识的基本层次，确立了理性的至高地位。西方的哲学思维方式本质上是理性主义，而中国传统哲学的思维方式却与其迥然而异：它无疑也含有理性主义的因素，但并不归结为理性主义；它较注重悟性、直觉和体验，但又不归结为非理性主义和直觉主义。它在本质上更具有“悟性”的色彩，是“悟性主义”。。 儒家的“格物致知”，通俗地说，就是用既有的思维尺度、框架去衡量、测度对象。只是这种把握绝非理性主义，它更具有“豁然贯通”的悟性特色。“季文子三思而后行。子闻之，曰：再，斯可矣。”由此可见，在孔子看来，如若过多地理性思考，结果可能适得其反，往往反致迷惑。老子的“玄览”，概括了道家的根本思维方式。“心居玄冥之处，览知万物”，从最超验的层次对事物的一种整体性的观照和透察。超验即要排除一切感性经验、语言概念和欲望，保持内心的清静和安宁。只有如此，才能做到“常无欲，以观其妙”。 中国佛教特别是禅宗是中印文化融合的产物，又吸收了儒家特别是道家的要素，凝聚了中国乃至东方悟性思维的精华。在佛家看来，“开悟”是修行之目的，而“菩提”为所悟之智，“涅”为所悟之理，佛及阿罗汉则为所开悟者。佛教义理对“悟”或“了悟”有甚为精密、详尽的研究和解说。依所悟之程度，将悟分为“小悟”和“大悟”；依所悟之迟速，将悟分为“渐悟”和“顿悟”；依所悟之途径，将悟分为“解悟”和“证悟”（由理解真理而知者为解悟，由实践修行而体得真理者为证悟）；依所悟之主体，将悟分为“悟自”和“悟他”，更为重要的是，佛教在长期的历史发展过程中，创造和积累了一整套系统而完备的了悟的方法，堪称无数佛教大师和佛教徒通过世代刻苦修行实践所取得的丰富的悟性体验的结晶。这种悟性主义的思维方式和思维特质尤其在中国禅宗中得到典型的充分的呈示。 中国传统哲学的悟性主义思维方式在儒家、道家和中国佛教特别是禅宗的悟性理论中体现得最为集中和鲜明。总体上说，以儒道释特别是中国禅宗为代表的中国传统哲学的悟性思维方式，完全超出了康德所划定的“感性、知性、悟性”的认识框架，超出了了康德将理性视为认识的最高形式的观点，从而也
广西柳州市2019届高三英语3月模拟考试试 卷 一、阅读理解（共15题；每小题2分，满分30分） 1.阅读理解 Unbelievable Stories of Animals Acting Just Like Humans Horses are picky eaters Horses have an even better sense of smell than humans do. When horses raise their noses and open their nostrils (鼻孔) , their nervous system allows them to sense smells we can't sense.

Whale says thanks In 2011, a whale expert spotted a humpback whale trapped in a fishing net and spent an hour freeing it. Afterward, in an hour-long display of thanks, the whale swam near their boat and leaped into the air about 40 times. Pandas like to be naughty
