17.The number of people hiding their identity while surfing the web has risen in the past year.
Research shows that the level of"encrypted"internet activity has risen dramatically across the world,suggesting that millions of people have begun to use sof
tware that hides who they are while accessing the web.
According to Sandvine,the technology networking company,hidden internet traffic in peak hours in Europe has been up to 6.1per cent of all web activities compared with about 1.5per cent a year earlier.In North America encrypted traffic went up to 3.8per cent from 2.3per cent a year earlier,while in Latin America it jumped to almost 10.4per cent from 1.8per cent.
Experts said that the changes in online behavior were the result of exposure(曝光) about widespread internet spying by intelligence agencies,such as that exposed by Edward Snowden,the US National Security Agency whistleblower.
"It will be interesting to see how these trends develop,"said Ernesto Van der Sar,the pen-name used by the editor-in-chief of Torrentfreak.com,the website that first reported the figures."In any case,it's clear that internet services and their users are becoming more aware of their privacy online,which is generally a good development."
Last week Sir Tim Berners-Lee,the British inventor of the web,defended the right of agencies to spy on the internet for law enforcement (强制实施).He said,"We have to figure out how to balance that against rights."

A.To cheat others.
B.To have more fun.
C.To follow the fashion.

5.Do American children still learn handwriting in school?In the age of the keyboard,some people seem to think handwriting lessons are on the way out.90% of teachers say they are required to teach handwriting.But studies have yet to answer the question of how well they are teaching it.One study published this year found that about three out of every four teachers say they are not prepared to teach handwriting.Some teachers are teaching handwriting by providing instruction for 10-15 minutes a day,and then other teachers who basically teach it for 60 to 70 minutes a day-which really for handwriting is pretty much.
  Many adults remember learning that way-by copying letters over and over again.Today's thinking is that short periods of practice are better.Many experts also think handwriting should not be taught by itself.Instead,they say it should be used as a way to get students to express ideas.After all,that is why we write.
  Handwriting involves two skills.One is legibility(清楚易认),which means forming the letters so they can be read.The other is fluency-writing without having to think about it.Fluency continues to develop up until high school.
  But not everyone masters these skills.Teachers commonly report that about one fourth of their kids have poor handwriting.Some people might think handwriting is not important any more because of computers and voice recognition programs.
  But Steve Graham at Vanderbilt says word processing is rarely done in elementary school,especially in the early years.American children traditionally first learn to print(用印刷体写),and then to write in cursive(草体字),which connects the letters.But guess what we learned from a spokeswoman for the College Board,which administers the SAT college admission test.More than 75 percent of students choose to print their essay on the test rather than write in cursive.
58.We can learnAfrom Paragraph 1.
A.teaching handwriting is a basic requirement in teaching job
B.most teachers prefer to teach handwriting
C.teachers spend little time in teaching handwriting
D.a keyboard has taken the place of the handwriting entirely
59.Which of the following is WRONG for traditional handwriting in the USA?B
A.The students are taught by practicing a long period.
B.To write in cursive is taught first.
C.Handwriting includes two skills.
D.The letters are repeated many times.
60.The best title for the passage isD
A.How to improve handwriting in school 
B.Handwriting lessons are on the way out
C.Handwriting involves two skills           
D.Right or wrong:the death of handwriting
61.The author's attitude towards whether still to learn handwriting in school isD.
A.negative    
B.optimistic           
C.critical(批评的)   
D.objective(客观的)

12.John Barry was born in Ireland in 1745.At the age of 15,driven by the British from his hometown,he got onto a ship secretly.It was leaving for the American colonies (殖民地).The ship took him to Philadelphia,Pennsylvania.As Barry stepped off the ship,he had no idea that he would become one of America's important historical figures.
Barry grew to be over six feet tall.During his time as a sea captain,he set a model for the new navy (海军).He was well-known for his bravery and fairness.He had strict rules for his men,including no alcohol on the ship.Of Barry,historian John Frost,in his 1844American Naval Biography wrote,"Barry's operations were not surpassed (超越) during the war."
When the American War of Independence began,Barry discovered a secret British plan.The British wanted to block the Delaware River and catch every ship sailing to or from Philadelphia.The idea was to starve the American colonists.Barry worked quickly to change merchant ships (商船) into warships.Then he fought the British from a tiny ship.He managed to keep them from getting control of the Delaware River.After his ship sank,he set up his guns on shore.From there he joined in the battles of Trenton and Princeton.Then Barry commanded the American warship Lexington and caught the Prince Edward,the first British ship taken in the war.
After the war ended,Barry suggested to the U.S.government that it should have a standing navy.It was the best way to protect its long coastline.He was made captain of the first U.S.Navy in 1794.He personally trained the men.Barry left no children when he died in 1803.However,he is called a father.He is the"Father of the American Navy."

2.For 40years,people in London have been happy to see parakeets (马尾鹦鹉) in their parks.The shocking green body and long tail have brought a bright color to the parks,which have attracted a lot of people.
However,the parakeets are no longer welcome.They will push out local birds from trees to build their own nests,and will also take most of the food in the parks,such as seeds,fruit and nuts.
Sometimes by accident,plants and animals are carried to new places.They are transported by trains,ships or even planes.Often,animals like fishes get transported in the water containers of ships.When these ships reach new places and pump out the water from their tanks,these animals will start a new life in a new place.
Sometimes people take plants and animals from one part of the world to the other to solve a problem.But it will create a bigger problem.Years ago,the farmers of northern Australia brought the toads (蟾蜍) from South America to their farms.They thought they would kill the beetles that harm the sugarcane crops.But the toad has done much more.It is now killing Australia's native animals,such as snakes,water birds and so on.
32.People get interested in parakeets mainly because ofA.
A.their appearance   
B.their singing
C.their behavior     
D.their living environment
33.How do the parakeets affect the local birds?C
A.They sometimes kill the local birds.
B.They destroy trees which the local birds live in.
C.They take the local birds'nests and food.
D.They have attracted much of people's attention.
34.What is the third paragraph mainly talking about?A
A.How animals and plants come to new lands.
B.How a new animal affects the local animals.
C.Why some plants are introduced to a new place.
D.The role of ships in transporting animals and plants.
35.What can we learn about the toads?D
A.They didn't kill the beetles at all.
B.They were brought to Australia by accident.
C.They have ruined the sugarcane crops.
D.They have created a larger problem in Australia.

9.Black Friday is the day after Thanksgiving Day and the Friday before Cyber Monday in the United States.It is a busy shopping day and is a holiday in some states.For many American consumers,it is the day when you can get great deals on goods that may eventually become Christmas presents.Many people have a day off work or choose to take a day from their quota of annual leave on Black Friday.
But why is it"black"Friday?There are a couple of stories.But the most commonly cited one has to do with ink,paper,and accounting.By the early 1980s,a theory began to be circulated:that retailers traditionally operated at a financial loss for most of the year (January through November) and made their profit during the holiday season,beginning on the day after Thanksgiving.
When this would be recorded in the financial records,once-common accounting practices would use red ink to show negative amounts and black ink to show positive amounts.Black Friday,under this theory,is the beginning of the period when retailers would no longer have losses (the red) and instead take in the year's profits (the black).
The Christmas shopping season is of enormous importance to American retailers and,while most retailers intend to and actually do make profits during every quarter of the year,some retailers are so dependent on the Christmas shopping season that the quarter including Christmas produces all the year's profits and compensates for losses from other quarters.So there you have it.It's about how much money retailers are making from you and me.

28.According to the first paragraph,Black Friday isD.
A.the Friday before Thanksgiving
B.the Friday when Americans can have a day off
C.a federal holiday in the United States
D.a public holiday in some states of America
29.What is the origin about Black Friday according to the passage?B
A.There are many different stories about it including some religious ones.
B.It is maybe about once-common accounting practices.
C.It is because so many people go shopping that day that it always leads to tragedies.
D.It is to show respect for the ancient.
30.What do we know from the passage?B
A.All the retailers depend on the profits on Black Friday to compensate for the previous loss.
B.Black Friday is a great chance for retailers to make profits.
C.Christmas shopping season is the only profitable season to the retailers.
D.most retailers are in red before the Christmas shopping season.
31.What is the best title of the reading passage?C
A.Black Friday's origin.
B.Black Friday in the United Kingdom
C.Black Friday and its origin
D.Stories about Black Friday.

7.Cleverness is a gift while kindness is a choice.Gifts are easy-they're given after all.Choice can be hard.
I got the idea to start Amazon 16years ago.I came across the fact that the Internet usage was growing at 2300percent per year.I'd never seen or heard of anything that grew that fast,and the idea of building an online bookstore with millions of titles was very exciting to me.I had just turned 30years old,and I'd been married for a year.I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't and I wasn't sure what to expect.MacKenzie told me I should go for it.As a young boy,I'd been a garage inventor.I'd always wanted to be an inventor,and she wanted me to follow my passion.
I was working at a financial firm in New York City with a bunch of very smart people and I had a brilliant boss that I much admired.I went to my boss and told him I wanted to start a company selling books on the Internet.He took me on a long walk in Central Park,listened carefully to me,and finally said,"That sounds like a really good idea,but it would be an even better idea for someone who didn't already have a good job."That 1ogic made some sense to me,and he convinced me to think about it for 48hours before making a final decision.Seen in that light,it really was a difficult choice,but finally,I decided I had to give it a shot.I didn't think I'd regret trying and failing.And I suspected I would always be haunted by a decision to not try at all.
After much consideration,I took the less safe path to follow my passion,and I'm proud of that choice.For all of us,in the end,we are our choice.

21.What inspired the author with the idea of building an online bookstore?C
A.His dream of being an inventor.
B.The support of his wife.
C.The greatly increasing usage of the Internet.
D.Millions of exciting titles,
22.Which of the following is closest in meaning to the underlined sentence?A
A.The idea of not trying would keep coming to his mind and disturb him.
B.He would be very excited if he tried it out.
C.He would be always having a doubt if he didn't try.
D.The decision to not try the online bookstore would terrify him.
23. Which of the following would be the best title for the passage?D
A.Cleverness and Kindness     
B.The Starting of Amazon
C.Following My Passion     
D.We Are What We Choose.
