There are hundreds of publishers across the world and millions of books get printed every year. Moreover, a book can be printed by several polishers.1.
To overcome the problem of identifying books, publishers have come up with a unique numbering system. For instance, if 50,000 copies of The Adventures of Sherlock Holmes are printed by a publisher at one time (called an edition), all of them are identified by one number code. 2. your address begins with your house number, street, locality, state and ends with a statement of the country where you live. An ISBN book number achieves a similar aim of identifying and tracing a book
If you pick up any book, turn it around you will see a number which looks something like this — ISBN 90-70002-34-5. This is called the ISBN number. ISBN stands for International Standard Book Numbering. 3. The ISBN number is divided into four groups that are separated by a space or a hyphen.
The first part of the ISBN identifies the country and is called the Group Identifier. 4.The second part is called the Publisher Prefix. The Publisher Prefix is used to identify the publisher of the book. The publisher prefix may contain up to seven digits.
The third part identifies the title and the edition of the book and so is called the Title Identifier, which may consist of up to six digits. 5.Since you can have the same book from the same publisher but with different editions, the Title Identifier helps to differentiate between them.
The fourth and the final part is called the Check digit, a single digit (from 0 to 9) used to check whether the given ISBN number is correct or wrong. If an ISBN number is incorrect, this means that the book is a version printed illegally.
A.It may consist of up to five digits.
B.So what can the ISBN number do for you?
C.This makes the task of identifying a book very difficult.
D.It is a numbering system that is used to describe the book.
E.Book publishers often come out with newer and updated versions of earlier books.
F.The number Code is your home — address that can only be shared by your parents and
G.The ISBN numbering system helps book stores and book publishers to handle categorize to handle, categorize, store and identify books easily.
People may set an alarm on the phone or clock that sounds like this: beep beep beep. That hard, unpleasant sound may be making it harder to shake off the sleepy feeling in the morning known as grogginess. So, is there a better way to wake up? A recent study says yes. The answer is music.
The study, carried out by researchers in Australia, involved 50 people. The researchers found that people who wake up to musical alarms reported feeling more awake and alert. Stuart McFarlane, a lead writer of the study stated, "We are very surprised by these findings as one might expect a harsh beeping sound to be more successful," at waking up a person.
Sleep inertia is another term for grogginess. It means a person has a heavy feeling when waking up, and has trouble getting moving again after sleeping. McFarlane said people need to better understand sleep inertia's harmful effects on human performance later in the day.
Not everyone will experience the full effect. But for those who do, "care should be taken" when performing duties that require a top performance within this period, he said. This includes "dangerous tasks like driving or riding our bikes" shortly after waking up. The same is true for people who work in dangerous situations shortly after they wake, including firefighters and pilots.
So, what makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a "beeping" alarm. McFarlane said that the changes over time between the music tones may help increase a person's attention when waking from sleep.
And is there a kind of music that is best to wake up to? There may be, McFarlane said. "We could suggest alarm sounds that are tune full and easy to hum or sing along with. The current sounds I have been using include 'Close to me' by the Cure and 'Borderline' by Madonna."
No matter how you wake up, experts say, the amount of sleep you get also matters — a lot.

With Chinese consumers hit by quarantine （隔离期）and travel restrictions as well as just cautious about going out to the shops due to the coronavirus epidemic（流行病），companies in China are experimenting with new tricks to make sales.
Oil giant Sinopec — keen to get customers back in their cars and help farmers due to roadblocks — launched a new project last month called "zerotouch" vegetable sales at its 6,000 gas stations in 147 Chinese cities. Consumers place and pay for orders on the app and when they drive up, gas station employees put the vegetables into their car trunk, eliminating any need for human-to-human contact.
"The coronavirus outbreak has made it difficult for people to shop as before," said Li Hong， vice president of Sinopec's convenience store sales division. "Travel demand has been falling, but demand for food is pretty rigid."
Mengniu Dairy, China's dairy producer, is racing to add more vending machines to the 10,000 it currently has, saying the epidemic has driven unexpectedly strong demand for the sales channel. Its system allows customers to order products like milk and yoghurt online which can then be picked up from their local vending machine. "The virus outbreak has decreased consumption for dairy products as people are unwilling to go to the supermarket," said Meng Fanjie, head of the company's Communist Party committee. Luckin Coflfee, a competitive rival to Starbucks, now also offers the sanitizer (消毒） products （e.g. hand soap） besides coffee. Liu Xingliaging, an independent retait analyst, said, however, that Luckin's strategy would have only a modest impact. “At best some users will place an order when they buy coffee, but nobody is deliberately choosing the Luckin app just to buy sanitizer.”
1.According to the passage, why did some companies adopt new selling methods?
A.Citizens were not allowed to go out.
B.The demand for travel and food declined sharply.
C.The coronavirus epidemic changed people's way of life.

2.What does the underlined word "eliminating" in Paragraph 2 most probably refer to?
A.meeting B.removing
C.decreasing D.limiting
3.The passage is written mainly to .
A.illustrate the difficulty caused by the coronavirus epidemic
B.explain the changes made by some companies in the epidemic
C.describe the challenges some companies met during the epidemic
D.reveal the intelligence people showed in the coronavirus epidemic
Do you have a job? If you do, you’ll know the world of work can be tough-long hours, boring tasks and stress. But it can bring benefits too, such as a regular salary. Maybe that's why more of us are now taking on a side hustle — another name for a second job.
For some having two jobs is a necessity — a way to make ends meet and provide extra income. But it now seems that more people want to put their skills and passions into practice to make money. These tend to be entrepreneurial young people who want to work on their own projects alongside their main source of income.
According to Henley Business School, around one in four workers run at least one side hustle business, half of which were started in the past two years. Those aged 25 to 34 are most likely to be involved, with 37 percent thought to run a sideline of some kind. It calculates that the average side hustler makes about 20 percent of their income through their second job.
But what's interesting is that many millennials （千禧一代）are turning their hand to new jobs not just for money and security. Research has found that almost three-quarters of people are following a passion or exploring a new challenge. Becci Mai Ford, who works some of the time for a telecommunications company to pay the bills, spends the rest of her time developing her craft company. She says going full-time is "not financially worth it right now but it fuels my creative soul and makes me happy".
Of course having a side hustle means you are self-employed, which can give you flexibility to work when you like, but it can be risky. You sometime work on a zero-hours contract and may not get offered enough work. Or what was originally your passion may become more of a chore. However; this could be the best way to try out a new career or follow a passion while not giving up the day job.
1.According to the passage, which of the following is NOT the reason for people to take on a side hustle?
A.To make money. B.To obtain job satisfaction.
C.To have the flexibility to work. D.To enjoy a risky lifestyle.
2.The author explains the study from Henley Business School by .
A.describing the process B.making a comparison
C.presenting research findings D.analyzing cause and effect
3.What is the author's attitude towards having a second job?
A.Critical. B.Indifferent.
C.Neutral. D.Favorable.

Dear editor,
1 am Li Hua,an exchange student from China.I am writing to point out to you some of the mistake in your recent article about the Chinese Dragon Boat Festival.
The Chinese Dragon Boat Festival falls May 5th in the Chinese Lunar Calendar,not the calendar using around the world.Also,we compete with dragon boats,where there was always a dragon head at the front,not rowing boats.To correct the mistakes is constructive but thus readers can have the better understanding of China.However,I quite appreciate your efforts to introduce Chinese culture to our people.In my opinion,it is no doubt that it will sure bridge the gap between our countries.
Thank you for your efforts.Wish you all are the best!
Yours.
Li Hua
