Harry Potter fans who have found years of happiness, excitement, and comfort in J.K. Rowling’s successful series are passing those feelings on to new readers by leaving touching notes hidden in the books’ pages.
As part of a new campaign called #PotterItForward, they call themselves Potterheads and write messages about their own experiences with Harry, Ron, and Hermione. Before they leave their surprising notes behind, they’re taking photos and sharing them on Instagram to inspire other readers to do the same.
According to https://www.doczj.com/doc/7512266892.html,, the movement began from the Harry Potter fan site MuggleNet, which included a yellow Post-It note inside a copy of Harry Potter and the Half-Blood Prince. “The world of Harry Potter saved me during my darkest times,” the note read. “Use this to es cape from reality and to let your imagination free. Never forget that you are amazing.”
Adding an explanation to the picture, MuggleNetencouraged other fans to follow suit(效仿). “Join our global movement and #PotterItForward by leaving a magical note in a bookstore or a library’s copy of Harry Potter series!”
And plenty of fans do. “Welcome to Hogwarts!”A fan wrote in a copy of Harry Potter and the Sorcerer’s Stone. “From my Potter generation to yours, I hope you find a home in these pages like I did. On a bad day, I know I can still turn to Harry, Ron, and Hermione to make me feel comfortable with myself again.”
Another fan, @willowmahogany13, left the message, “Whether you’re a seasoned(经验丰富的) reader or a fresh newcomer, I hope the adventures and messages this series bring provoke(刺激) your thoughts in some way or at the very least, give you a great story to enjoy.”
Though the movement began in the U.S., it now spreads all over the world, as Harry Potter series have been published in at least 70 languages. Fans in Russia, the Czech Republic and Scotland—where Hogwarts is located—have also shared photos of notes they’ve left or found in the books.
24. What do Harry Potter fans do before they leave a touching note in a book?
A. They find a copy of Harry Potter series.
B. They join the global movement of #PotterItForward.
C. They take a photo of the note and share it on Instagram.
D. They write their own experiences on a yellow Post-It note.
25. What can we learn from Harry Potter series?
A. We should believe in ourselves.
B. We should use our imagination.
C. We should share our experiences.
D. We should feel comfortable with ourselves.
26. What would be the best title for the text?
A. J.K. Rowling’s Harry Potter Series Are Successful
B. Harry Potter Fans Find Happiness from the Series
C. Social Media Makes Harry Potter More Popular
D. Harry Potter Fans Have Started a New Campaign

Cigarette smoking has hit the lowest point among American adults, a new report found.
The percentage of U.S. adults who smoke cigarettes was 17.8% (about 42.1 million) in 2015, a drop from 20.9% in 2005, even though the population of America remains almost the same. “There is encouraging news in this report, but we still have much more work to do to help people give up,” Dr. Tim McAfee said, who is in charge of the report.
The decline in smoking rates varied among different populations and regions. Smoking remains particularly high among people who live below the poverty level, those who receive less education, and those with disabilities.
The smoking rate is also high among Americans of multiple(多种的) races, American Indians and Alaska Natives, compared with people of other races. People in the Midwest had the highest smoking rate, about 20.5%. The smoking rate was 19.2% among people in the South, and 16.9% among people in the Northeast. People who live in the West had the lowest smoking rate (13.6%).
Cigarette smoking is considered the leading cause of disease and death in the U.S., killing more than 480,000 Americans each year. “We can reduce cigarette smoking rates if strategies proven to work are adopted,” said Brian King, a senior scientific adviser. “These strategies include creating tobacco control programs, increasing prices of tobacco products and carrying out smoke-free laws. These strategies will
help cut down the smoking rate and thus reduce the tobacco-related deaths.”
The report found that current smokers are cutting down on cigarettes. Among current cigarette smokers, the proportion(比例) of those who smoke every day was 76.9% in 2015, decreasing from 80.8% in 2005.
“But as for my advice, reducing a few cigarettes a day instead of quitting completely does not produce significant health benefits,” McAfee said. “Smokers who quit before t hey’re 40 years old can live 10 years longer.”
27. Smoking rates remain relatively low among those who ______.
A. live a poor life
B. receive more education
C. are disabled
D. are American Indians
28. What can be concluded from Paragraph 4?
A. Smoking rates vary from region to region in America.
B. People in less developed regions have a tendency to smoke.
C. Fewer and fewer Americans have become addicted to smoking.
D. The smoking rate among people in the West remains very high.
29. Brian King’s wo rds in Paragraph 5 mainly focus on ______.
A. the positive effects of the strategies
B. the harmful effects of cigarette smoking
C. the diseases caused by cigarette smoking
D. the measures taken by the U.S. government
30. What is McAfee’s suggestion to s mokers?
A. They should quit smoking completely.
B. They should take their own health seriously.
C. They should learn how to live a longer life.
D. They should smoke less when they are young.

概要写作（满分25分）
阅读下面短文，根据其内容写一篇60词左右的内容概要。
Computers have changed the way a business functions to a large extent. In the past, corporate houses rented spaces for running accounting departments. It took months together to figure out profit or loss that a business had made or suffered. However, computers have become the backbone of all businesses now. Today, computers are used beyond bookkeeping (记账) purposes too. Almost everything that happens in an organization is recorded, worked upon and evaluated with the help of computers.
Imagining our lives without computers is next to impossible. Computers were initially used only in workplaces. However, they soon became a household name, which revolutionized everything from school homework to grocery shopping. When the Internet came into being, it caused a great change in the way we functioned. Over a period of time, computers enabled working from home, which created a new type of employment. This gave usage of computers, within the confines(界限) of homes, a new part. As technology progressed, simple things such as shopping, booking tickets, buying a new house, searching for schools and colleges, researching for projects and medical information became a lot easier with entry of computers in every household.
As an indispensable tool in our lives, computers have changed the way we think in more ways than one. Today, all you have to do about finding answers is just “Google it”! The online world of blogging, instant messaging, chatting and social n etworking
not only leaves virtual traces, but unites the world in a completely unimagined way. This powerful medium is the great mode of mass communication which affects our thinking by providing people with a platform to voice their opinions and begin discussions that have brought about a change in the world.
Computers have pushed us to see different worlds and experience different cultures. The revolution in Egypt is the latest example of how computers changed the world. Today the identity of information technology is computers. Invention of this machine has changed the world’s perspective about cultures, economics, history and current affairs. The advent (到来) of computers has no doubt brought a revolutionary change in our existence.

2018年浙江省杭州高中高考英语最后一卷 副标题 一、阅读理解（本大题共10小题，共25.0分） A One day your pocket might power your smart phone．Soon you may never have to worry about your smart phone running out of juice．Your clothing will simply power it back up for you．That's the word from scientists at China's Chongqing and Jinan Universities in a study just published in the journal ACS Nano． Researchers have been hard at work during the last few years trying to create wearable energy，or clothes that can charge things．The assumption is simple．People today rely heavily upon devices such as smart phones and tablets．And they're looking for ways to recharge these devices on the go．So if you could design clothing fabric that could make use of solar power -one of the most widely available and inexhaustible renewable energy sources - you'd be able to charge your various devices with ease． Scientists have had some past success creating energy-harvesting fibers．But there was always one problem when they tried to fashion these threads into self-powered smart clothes：The fibers they designed got damaged during the clothing manufacturing process，namely during the weaving and cutting．The Chongqing and Jinan University scientists say they've solved this problem because the energy-collecting and energy-storing threads they created are highly flexible - each individual thread is easily bendable，and not simply the fabric as a whole．The team's sample textile can be fully charged to 1.2 volts in 17 seconds by exposure to sunlight - enough voltage that your future smart T or smart dress might be able to power small electronics．It's durable，too；their research showed there was no descent in the fabric after 60 days．But don't worry that this means the fabric is similar to rough cloth．The scientists note their textile can be fashioned into numerous different patterns，and tailored into any designed shape，without affecting performance． 1.What does the underlined phrase "running out of juice" in paragraph 1mean？______ A. Being lacking in energy． B. Wanting to have some juice． C. Being picked out of a drink． D. Having some water running out． 2.Why could smart dress charge a phone？______ A. A solar cell is attached to the dress． B. The fabric of the textile contains current． C. The fabric of the textile is easily bendable． D. The fabric of the textile could collect and store the solar energy． 3.What is the scientists' attitude towards the scientific technology？______ A. Optimistic． B. Pessimistic． C. Neutral． D. Doubtful． 【答案】 【小题1】A 【小题2】D 【小题3】A 第1页，共13页
