【题目】 Wikipedia, the online encyclopedia (百科全书), is the largest encyclopedia ever. An encyclopedia is a collection of informative articles about various things. Encyclopedias used to be printed as books. 【1】
“Wiki”is an internet term that means”a website that can be edited by the public. “It comes from”wikiwiki”，a Hawaiian word for”quick”. Two Americans, Jimmy Wales and Larry Sanger, created Wikipedia in 2001.【2】It has about 6 million articles in 300 languages and is visited by billions of people each day,who want to find information on just about anything-science, math, languages, art, cultureand company histories. There are articles on sports stars, too, and even long-forgotten soap operas from the 1970s.
【3】Except for a small number of pages, anyone can edit articles, anonymously (匿名地) or with a user account, and registered users can create their own articles. Editing is unpaid, although Wikipedia does employ a small staff. Wikipedia is freely available to anyone with an internet connection. Its founders hoped that the model would make use of humanity’s collective knowledge.
【4】Many Wikipedia pages contain errors, although the organization has a content review system that works to fix this problem. Several studies have concluded that Wikipedia is as accurate as most print encyclopedias. Indeed, a 2005 report in the journal Nature found it to be only slightly less reliable than Encyclopedia Britannica.
Today Wikipedia faces many challenges. It does not rely on advertising. 【5】Perhaps more importantly, the number of its volunteer editors is shrinking.
Despite these difficulties, Jimmy Wales says he will still stick to his dream. He has big plans for the future. He wants Wikipedia available in all of the world’s languages.
A.Instead, all of its funds come from donations.
B.Wikipedia employs an open editing model.
C.It allows users to get information within seconds.
D.It is now the fifth-most visited website on the Internet.
E.Most of its editors are volunteers.
F.Now,they are mostly found online.
G.However,some people doubt the accuracy of Wikipedia's content.
【答案】
【1】F
【2】D
【3】B
【4】G
【5】A
【解析】
本文是一篇说明文，介绍了维基百科的相关内容。
【1】
根据上文Encyclopedias used to be printed as books.可知百科全书以前是以书籍的形式印刷的。由此可知，本句是在说明百科全书目前的情况，前后时间上形成对比。此外F中的代词they指代前一句中的Encyclopedias。故F选项“现在，他们大多在网上找到”符合上下文语境，故选F。
【2】
根据上文“Wiki” is an internet term that means” a website that can be edited by the public. “It comes from “wikiwiki”，a Hawaiian word for “quick”. Two Americans, Jimmy Wales and Larry Sanger, created Wikipedia in 2001.可知“维基”是一个互联网术语，意思是“可以由公众编辑的网站”。它来自于夏威夷语“wikiwiki”，意思是“快”。两名美国人，Jimmy Wales和Larry Sanger在2001年创建了维基百科。以及后文It has about 6 million articles in 300 languages and is visited by billions of people each day, who want to find information on just about anything-science, math, languages, art, culture and company histories.可知它有300种语言的600万篇文章，每天有数十亿人访问它，他们想要找到关于任何东西的信息——科学、数学、语言、艺术、文化和公司历史。由此可知，上文介绍了维基百科名字的由来、创始人、以及所收藏的信息，本句承接上文继续围绕维基百科介绍。且后面句子里的主语it，与D 选项中的it指代一致。故D选项“它现在是互联网上访问量第五大的网站”符合上下文语境，故选D。

【4】
本句的位置在段首，引出一个新的话题。结合后文Many Wikipedia pages contain errors, although the organization has a content review system that works to fix this problem.可知许多维基百科页面包含错误，尽管该组织有一个内容审查系统来修复这个问题。由此可知，本段介绍的维基百科所存在的问题，G选项中however是一个重要的衔接标志词，表明后面的内容与前面的信息相反。故G选项“然而，有些人怀疑维基百科内容的准确性”符合上下文语境，故选G。
【5】
该题位于段落之中。根据上文It does not rely on advertising.可知它不以广告盈利。由此可知，本句是在说明维基百科的资金来源，A选项中instead作为一个重要的衔接标志词，使得该句与前句形成对比。故A选项“相反，它所有的资金都来自捐赠”符合上下文语境，故选A。

【题目】 A few weeks ago, I picked up my 14-year-old daughter and her friend from dance class. The two girls chatted happily until I reached her friend’s house. And then 1 began the drive home and my daughter, who had been talking nonstop a minute before, went completely silent. I assumed she was lost in thought.
When I came to a stoplight, I looked in the mirror. My daughter wasn’t looking out of the window or staring into space - she was on her phone. I felt my anger rise.
“Get off your phone. That is rude. You make me feel like an Uber driver.” I shouted.
“But I’m texting friends about biology homework!’’ she said.
“That can wait.” I was mad and she was angry.
Back home, she disappeared into her room, and I thought about how I was still trying to take control of my daughter’s growing independence, which was fruitless.
The next day I was thinking about my outburst when a parenting program on TV caught my eye, in which the hosts interviewed Dr. Ken Ginsburg, the author of a famous parenting book. It completely changed my attitude.
Ginsburg said. “Why are our teens pushing us away? It’s not because they hate us - it’s because they love us so much and yet they know they have to become independent. So this is a process of figuring out how to push away the things they love the most. It is crazy to fly from a comfortable nest, so teens get ready for it by temporarily pushing their parents away.”
I need to honor her independence and create space for both of us to face this monumental developmental challenge as teammates, not adversaries((对手).
【1】What made the writer mad?
A.She served as an Uber driver.
B.The two girls were chatting happily.
C.Her daughter was playing with the phone.
D.Her daughter forgot her biology homework.
【2】What do we know about the daughter?
A.She is being under her mother’s control.
B.She is on the way to being independent.
C.She enjoys making friends using social media.
D.She hates making conversation with her mom.
【3】Which of the following best describes the mother?
A.Open-minded.B.Hardworking.
C.Inspiring.D.weak-willed.
【4】What is the passage mainly about?
A.I was pushed away by my teenaged daughter.
B.Life of a teenager is moving at its own slow pace.
C.Parents completely rely on parenting experts to educate children.
D.My relationship with my daughter was improved by a suggestion.

【题目】 A decade ago, colored lights danced around the living room on New Year's Eve and happy music was played. Upstairs, the children were asleep. But I wasn't feeling happy. In mid-December, my husband and I had been informed that he had cancer and that he was going to die. He had less than a year left, the doctors said.
In the years since that painful season, I have come to look back upon New Year's Eve as an ending and a beginning. New Year's Eve brings a halt to the endless commitments that fill our daily lives and a chance to reflect.
New Year's Eve is full of possibility and anticipation. What will be the surprising experiences and delightful successes in the coming year? But also, what disappointments are waiting for us in the next twelve months?
In many ways, New Year's Eve and the days that surround it are a line between past and future. That line is made up of a series of moments of transition that take us out of the old and into the new. Transition can be challenging for many of us. It's about letting go of the familiar and diving headlong （迅猛地） into the unfamiliar.
Just as, back then, I had to face letting go of the life I had led with my beloved husband and stepping into a new world as a widowed （丧偶的） mom. I find that each year I have to step out of the version of me that suited the year that is ending and ease into the version of me who will rise to the goals I am holding for myself for the year ahead.
Last year at this time, I sat in a chair in southern France and drank in the stillness and beauty of the countryside around me. The three children and I had brought into this world talked and laughed around the table beside me as we enjoyed a lunch of bread and cheese.
I was filled with a sense of joy and I had a glowing heart that was full of hope. It was another ending and another beginning. May we all transition into the best of what lies ahead. May we all find happiness this holiday season.
【1】What does the underlined word “halt” in Paragraph 2 mean?
A.Stop.B.Beginning.
C.Meaning.D.Tradition.
【2】What does the author think people should do at new year?
A.Set challenging goals for the next year.
B.Break with daily routines and form a new habit.
C.Spend more time with family members.
D.Think about the past and get ready for the future.
【3】What is the author's attitude toward the future?
A.Calm.B.Indifferent.
C.Doubtful.D.Expectant.
【4】What is the main purpose of the article?
A.To memorialize her husband.
B.To show how she got through a hard time.
C.To share her view of New Year's Eve.
D.To remind us that uncertainty is part of life.

【题目】 Two summers ago, Spencer Seabrooke stepped off the edge of a cliff and out into the air. He was held up by a narrow band of fabric, three centimetres wide. The slackline (扁带) went over a deep channel on the top of Stawamus Chief Mountain in Squamish, Canada. The plan was to walk across without safety equipment. The ground was 290 metres below Seabrook’s feet. A fall meant death. The walking distance of 64 metres would mark a world record in free solo slacklining.
“You’re standing on nothing,” Seabrooke said at the time. “Everything inside your body is telling you this is wrong.” Several steps into the crossing, Seabrooke looked down. He lowered his body to steady himself and reached with his hands to hold the slackline. He suddenly turned over but hung on. He righted himself, let out a few screams, and stood again. He had walked the same slackline-with assistance-many times before. Finally, he crossed in four minutes and made it.
Slacklining became known in the early 1980s, around the rock climbing scene at Yosemite National Park in California. Scott Balcom, in 1985, was the first to walk on a 17-metre highline on Lost Arrow Spire, the valley bottom some 880 metres below. Charles “Chongo” Tucker, who has been living in Yosemite for a long time, was there in slacklining’s earliest days. Later, in 1994, he was one of the next people to walk the Lost Arrow Spire highline. “As scared as I was, it was as cool as anything I’ve ever done in my life,” said Tucker.
Seabrooke grew up in Peterborough, Canada, in love with the outdoors. He saw a documentary in 2012 that was about Andy Lewis, a slackliner and free solo pioneer who performed at the Super Bowl. Seabrooke was attracted and devoted himself to the sport. Three years later, he walked his record free solo highline on the Stawamus Chief.
The attention Seabrooke won led to work, everything from commercials to paid appearances at slackline festivals from Poland to China. “When you step out into the air, there’s something so clean about it,” said Seabrooke. “Height makes it real.”
【1】What do we know about Seabrooke’s slacklining experience two years ago?
A.It was record-breaking.
B.It was done in Yosemite.
C.It involved materials for security.
D.It presented no challenge to him.
【2】What did Seabrooke’s words in Paragraph 2 imply?
A.He was very confident.
B.He made a wrong decision.
C.Slacklining was a dangerous sport.
D.Slacklining was done without any support.
【3】What was Tucker’s attitude to slacklining?
A.Negative.B.Ambiguous.
C.Frustrated.D.Favorable.
【4】What encouraged Seabrooke to start slacklining?
A.The Super Bowl.
B.A slackline festival.
C.Its commercial promise.
D.A slackliner’s performance.

【题目】 China’s war on garbage is as digital as the country itself. Think QR codes attached to trash bags that allow the government to trace exactly where its trash comes from.
On July 1, Shanghai began a compulsory garbage sorting program. Households and companies must classify their wastes into four categories and dump them in appointed places at certain times. The strict program became a headache for some residents. Not even the most environmentally conscious person can get all the answers right. Like, which bin does the newspaper you just used to pick up dog poop (粪便)belong to?
Gratefully, China’s tech startups are here to help. For instance, China’s biggest internet companies responded with new search features that help people identify what wastes are “wet”, “dry”, “toxic”, or “recyclable”. Simply pull up a mini app on WeChat, Baidu or Alipay and enter the keyword. The tech firms will give you the answer and why.
Alipay, Alibaba’s electronics payment company, claims its garbage sorting mini app added one million users under just three days. The mini app has so far indexed (编索引) more than 4,000 types of rubbish. Its database is still growing, and soon it will save people from typing by using image recognition to classify trash when they snap a photo of it. If people are too busy or lazy to hit the collection schedule, well, startups are offering trash service at the doorstep. A third-party developer helped Alipay build a recycling mini app and is now collecting garbage from 8,000 apartment complexes across 11 cities. To date, two million people have sold recyclable materials through its platform.
Besides helping households out, companies are also building software to make property managers, life easier. Some residential complexes in Shanghai began using QR codes to trace the origin of garbage. This way, regulators in the region know exactly which family has produced the trash and fine violators.
【1】What are some residents confused about?
A.Environmental knowledge.B.Bin for dog poop.
C.Some waste classification.D.Time for dumping.
【2】What is the advantage of trash service at the doorstep?
A.It provides time flexibility.B.It reduces household waste.
C.It saves people from typing.D.It classifies rubbish properly.
【3】Who will probably most welcome the use of QR codes?
A.Third-party developers.B.Company managers.
C.Community administrators.D.Rubbish collectors.
【4】What is the main idea of this article?
A.People need recycling apps badly.
B.People should classify their rubbish.
C.How regulators benefit from the tech.
D.How China uses tech to sort waste.

【题目】 In 1848 gold was found in California. Thousands of people rushed there to get some. Many people liked living there. But there wasn’t a whole lot between California (CA) and Missouri (MO), where the nearest trains ran. The train line to California wasn’t finished until 1869.
In I860 and 1861, the Pony Express was the fastest way to get news to and from the West. The trail that they rode was around 2000 miles long. It took most people weeks or months to ride that far. The Pony Express could make the trip in just ten days. Those speeds were unheard of at the time. So how did they do it? Well, they had a good system.
The Pony Express had 184 stations along the trail. The stations were around ten miles apart. This is about how far a horse could run at a gallop (疾驰) before tiring. The rider would switch to a new horse at each station. He would only take his mail pouch (邮袋) with him. Every 75-100 miles, the rider would get to a home station. At each home station, riders would rest. The mail never stopped moving, even while the horses and riders rested.
It was tough to ride for the Pony Express. Each rider had to weigh less than 125 pounds. Speed was the key. Most of the riders were teenage boys. They rode at a fast pace for up to 100 miles a day. If there were an emergency, one might have to ride 200 miles in a day.
The Pony Express filled an important role for a time, but it did not last. The Civil War started in April of 1861. On October 24th, 1861, the first telegraph line to California was finished. This linked them to the rest of the country. People could send messages in an instant. Two days later the Pony Express closed.
【1】Which happened first?
A.The Pony Express was started.B.The American Civil War broke out.
C.The train line to California was finished.D.Settlers rushed to California to find gold.
【2】How long did it take the Pony Express to send mail from CA to MO?
A.About 24 hours.B.About ten days.
C.About twenty days.D.About one month.
【3】What would a rider do at the home station?
A.Give his mail to a new rider.B.Rest a while and go on riding.
C.Collect new mail for customers.D.Feed the horse and check the mail.
【4】What is the author’s purpose in writing the text?
A.To prove communication industry develops rapidly.
B.To explain why horses were used to deliver mail.
C.To describe the I860 - 1861E Fastest Mail Service.
D.To tell the brave stories of the Pony Express.
