Have you ever wondered?
1.Why do airplanes take longer to fly west than east?
It can take five hours to go west-east from New York(NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon know as the jet(噴射) stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes movement a constams air speed thus go faster in the west-east direction when the air moving with the wind than in the opposite direction.
2 What would happen if the gravity on Earth was suddenly turned off?
Supposing we could magically turn off gravity. Would buildings and other structures float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed moving at over a thousand miles per hour. If you turn something round your head on a string, it goes around in a circle until you let go of the strong go of the string. Things not attacked to the Earth would fly off in a straight line . People in buildings would suddenly shoot  upwards at a great speed until they hit the ceiling. Most things would fly off into space.

Part 1V  Writing (45 marks)Section A (10 marks)
Directions: Read the following passage. Fill in the numbered blanks by using the
information from the passage.
Write NO MORE THAN THREE WORDS for each answer.
An apprenticeship is a form of on-the-job training that combines workplace experience and classroom learning. It can last anywhere from one to six years, but four years is typical for most. An apprentice spends the majority of the time in a workplace environment learning the practical skills of a career from a journeyman--someone who has done the job for many years. The rest of the apprentice's time is spent in a classroom environment learning the theoretical skills the career requires. Being an apprentice is a full-time undertaking.
One of the advantages of apprenticeship is that it does not cost apprentices anything. The companies that hire them pay for school. What's more, it offers apprentices an "earn while you learn" opportunity. They usually start out at half the pay of a journeyman, and the pay increases gradually as they move further along in the job and studies. Near the end of the apprenticeship, their wages are usually 90 percent of what a journeyman would receive. Apprenticeship also pays off for employers. It can offer employers a pool of well-trained workers to draw from.
Despite the advantages, apprentices are usually required to work during the day and attend classes at night, which leaves little time for anything else. Sometimes, they might be laid off(下崗) if business for the employers is slow.
Once they have completed the apprenticeship and become journeymen, they receive a nationally recognized and portable certification and their pay also increases again. Some journeymen continue employment with the companies they apprenticed with; others go onto different companies or become self-employed contractors.

Throughout history, people have been interested in knowing how languages first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about 3,000 languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers.
There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original (最初的) language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 yeas ago.
Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even died out completely. About 1,000 years ago, English was a little-known relative of German spoken on one of the borders of Europe.
If a language has a large number of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China can’t understand speakers from other parts.

A. most people in the world speak Chinese
B. there are thousands of languages in the world today
C. man has much knowledge about languages
D. some people know several languages
2 According to the passage, most European and Indian languages ____ .

A. Chinese         B. English          C. Spanish          D. German
4 According to the passage, ____ seems to have changed a lot.

In the past decade the popularity of rock climbing has greatly increased, and so has the number of injuries. It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year. Study findings revealed a 65 percent increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991and 2008.
The study, published in the online issue of the American Journal of Preventive medicine,found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2008. The most common types of rock climbing –related injuries were fracture(骨折) and sprains (扭傷)。The ankle was the most common body part to be injured (40%).Climers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.
Falls were the primary reason for injury with over three-quartes of the injuries occurring as the result of a fall. The severity of related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.
“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury, explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalizaton rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.
1.Which body part is most likely to get injured for a climber ?
A.The arm        B.The ankle     C. The knee     D. The hand
2.How many women climbers in American got injured while climbing a rock between 1991 and 2008 ?

The Mona Lisa, one of the world’s most famous paintings, has been recreated with 3,604 cups of coffee—and 564 pints of milk. The different colors were created by adding no, little or lots of milk to each cup of black coffee.
The recreated Mona Lisa measured 20 feet long and 13 feet wide. It took a team of eight people three hours to complete the work. It was created for The Rocks Aroma Festival in Sydney, Australia, and seen by 130,000 people who attended the one-day coffee-lovers event.
Elaine Kelly, one of the organizers from the Sydney Harbor Foreshore Authority, was delighted with the result. She said, “Each coffee cup was filled with varying amounts of milk to create the different shades(色度) of the painting. We wanted to create an element of surprise and a sense of fun in the way we communicated with the public.”
“Once we had the idea of creating an image(像) out of coffee cups we searched for something iconic(有代表性的)to reproduce(復(fù)制).And after some time we chose the most iconic painting in history. The Mona Lisa has been reproduced so many times in so many different mediums but, as far as we know, never out of coffee,” Kelly continued. “Besides, the idea is practical.”
“It was fantastic. It really looked like the famous painting—the Mona Lisa. It was wonderful,” said one visitor.
After much planning it was great to see it coming together so well and the 130,000 people who attended the event certainly enjoyed it and were deeply attracted by it,” said Kelly.

Not only that, the guests  are an interesting  mix .The last time I went to one , the guests were from France , India ,Denmark and  Nigeria; it was like a gathering  at the United Nations . In New York ,the mix is less striking . It’s  like a gathering at Bloomingdat="le’s" , a well-known de partment  store.
For New Yorkers, talking ,talking  about  other  parts  of the world  means Brooklyn  and Queens in New Yorkers.But at Mallery’s ,when I side that I had been to Myanmar recently, peo ple knew where it was , In New Yorkers people would think it was a usual culb.

When I first got an email account ten years ago, I received communications only from family,friends,and colleagues.Now it seems that every time I check my e-mail ,I have an endless seriers of advertisement and otner correspondence that do not interest the at all.If we want e-mail to continue to be useful,we need special laws that make spamming(發(fā)送垃圾郵件) a crime.
If lawmakers do not do something soon to prohibit spam,the problem will certainly get much worse。Computer programs allow spammers to send hundreds of millions of e-mails almost instantly 。as more and more advertisers turn to spam to sell their products ,individual(個(gè)人的)e-mail boxes are often flooded with spam e-mails。Would people continue to use e-mail if they ahd to deal with an annoying amount of spam each time?
This problem is troubling for inviduals and companies as well. Many spam emails contain computer viruses that can shut down the entire network of a company.Companies rely on e-mail on on e-mail for their Comployees to communicate with each other. Spam frequently causes failures in their local commnications networks, and their employees are thus unable to communicate effectively.such a situationg results in a loss of productivity and requires companies to repeatedly repair their networks.These computer problems raise productton costs of companies ,which are,in the end,passed on to the consumer.
For these reasons,I believe that lawmakers need to legislate (立法) against spam.Spammers should be fined,and perhaps sent to prison if they continue to disturb people.E-mail is a tool which helps people all over the world to communicate conveniently,but spam is destroying this conwenience.
1.What does the underlined word “correspondence” in the Paragraph 1 probably mean?                                                         
A.messages     B.ideas          C.connections         D.programs

There are many stereotypes( 定型 ) about the character of people in various parts of the United States. In the Northeast and Midwest, people are said to be closed and private. In the South and West, however, they are often thought of as being more open and hospitable . Ask someone from St. Louis where the nearest sandwich shop is, and he or she will politely give you directions. A New Yorker might eye you at first and after deciding it is safe to talk to you, might give you a rather unexpected explanation. A person from Georgia might be very kind about directing you and even suggest some different places to eat. A Texan just might take you to the place and treat you to lunch.
American stereotypes are abundant. New Englanders are often thought of as being friendly and helpful. Southerners are known for their hospitality and warmth. People from the western part of the United States are often considered very outgoing. These differences in character can be traced to different factors such as climate, living conditions, and historical development.
When travelling from place to place, Americans themselves are often surprised at the differing degrees of friendliness in the United States.
1 . The main idea of the passage is _____________.
