17．Li Daiyu and Liu Qian visited （61）their  （they） cousins in Canada．Rather than take the aeroplane all （62）the way，they took the train from west to east across Canada．The thought （63）thatthey could cross the whole continent was exciting．On the way to the station，they （64）chatted（chat） about the trip．It's said that Vancouver （65）surrounded （surround） by mountains is （66）more beautiful （beautiful） than any other city in Canada．It is（67）so wet there that the trees are （68）extremely（extreme）tall．That afternoon aboard the train，the cousins settled（69）down in the seats．They learnt cowboys who have a gift for riding wild horses would compete in Stampede．（70）Besides/Moreover，they also learned that the population of Canada is only slightly over 30million．

16．Three years ago，I met a little girl named Alicia．She had brown hair and big，green eyes．She looked like a normal 7-year-old girl．She had autism（自閉癥），but that didn't mean she wasn't bright．In fact，one day proved just that．
As I walked into the room to meet with Alicia，I noticed that she was sitting in the corner alone．"Hey there Alicia!What are you doing？"She immediately looked down．I was used to this．"Thinking．"She said．"About what？""Butterflies．""What about them？"Then，she looked me right in the eye and said"Today I was outside looking at flowers，and I saw a butterfly．I began chasing it and finally caught it．I took it inside to show the nurse and she said，‘Oh，honey，you have to let it go．'I didn't want to let it go．I was so happy I had a new friend，but the nurse said that if I didn't let it go，it would die．I didn't want it to die so I ran outside and let it go．I was so happy．"
After she told me her story，she put her head back down．I felt a tear．I couldn't believe that a 7-year-old girl with autism taught me about a life lesson．Happiness can be found in everyone and everything．
I later found out that she moved to a different hospital．Her mother died of cancer．After her mother died，her father couldn't handle an autistic child．Later he abandoned（拋棄） her．I was so heartbroken about this that I quickly took action to find her．
Five years later，I have a 12-year-old daughter with brown hair and big，green eyes．Her name is Alicia．I had found her after years of hope，loss，and just luck．She is my butterfly in life．

15．It u won﹩50，000，000would u still go to college？
Lots of people go to college so they have a chance to get a better job，but if you won﹩50million，would you still pursue（追求）a higher education？
Re：If u won﹩50，000，000would u still go to college？
I would surely still go to college if I had that much money，but I would not be competing for a scholarship on collegenet．com．I would probably still discuss things here and I would create other scholarships to help other people to go to college as well．
With﹩50million，I would not have to worry about getting a loan（貸款）from Chase Bank or finding scholarships to study abroad．I would have published several books by now as well，but I would still pursue my education．Going to undergraduate school is something that I really want to do because I want to become a Pediatrician．Money may buy a lot of things，but it does not necessarily give you knowledge and knowledge is what I am hunting for now．
I am not just going to school to get a better job； I am going to school to realize all of my dreams．﹩50million is a lot of money，but no amount of money can keep me from my dreams．
Veggie thought："Money may make things easier，but it is not everything．"
Re：If u won﹩50，000，000would u still go to college？
Would I still go？UMM，YES YES YES YES YES!!!!!
I still want to teach…I don't care if I have more money than Bill Gates…I still want to be in a classroom teaching!!And I need a degree to do that!Teaching is my dream job，and it would make me really happy．
I would  pay off my loans as well as my boyfriend's loans and help out a couple of friends who are having trouble with money．
Re：If u won﹩50，000，000would u still go to college？
I would still go to college．The only difference is with that much money to go to college I probably would stay in college longer and pursue a few extra degrees while I am there．I am looking for knowledge not money．The only problem is I need money to pursue knowledge．
Also I could set up scholarship funds and I could save some more for additional dreams that I have．

14．While only about 200 astronauts have had the excitement of looking down at Earth and commanding systems on the International Space Station，actually thousands of everyday middle-school students have experienced  by Middle School Students，or EarthKAM，a camera system．
EarthKAM is an educational activity and outreach（擴(kuò)展）investigation that also results in temote Earth sensing and observation．Using the Internet，the students control a special digital camera fixed aboard the space station，enabling them to photograph the Earth's cosastlitnes，mountain ranges and other geographic items of interest from the unique advantage point of space．While EarthKAM offers a powerful way for students to investigate Earth from the unique perspective of space，it is also inspiring the next generation of flight controllers for space programs---involving university students to control and operate the camera system and related activities from the ground．
In the interview，Brion Au，one of the investigation developers at NASA's Johnson Space Centre，said，"EarthKAM is a payload（有效載荷）by students，for students．They are in chaerge．This system provides a viewpoint that the astronauts have…it's just awe-inspiring!"So far，students have captured more than 40，000 photos of the Earth from the space station as it orbited the Earth once every 90 minutes，traveling at 17，500 miles an hour．The team at EarthKAM posts these photographs online for the public and participating classrooms around the world to view．
Au explains that this education investigation is inspiring students to explore the world by examining Earth，while promotion social studies，art，geography，science，technology，and math，DR，Sally Ride，originally flying on the shuttles．The camera is located in the window Observational Research Facility，also known as the WORF，one of many the station's research facilities．

13．Was the London Olympics a success？Many people hold different opinions．However，one thing is certain，London could win a gold medal for hosting the"greenest"Games ever，BBC News reported．
Previous Olympic hosts have been criticized for the environmental damage they have caused through construction，waste and transport．But things had to be different in London because seven years ago it bid for the Olympics through the concept of"a One Planet Olympics"．
What is most impressive is that London the construction of the Olympic Park as an opportunity to clean up polluted areas---2 million tons of polluted soils were removed and 200 old factory buildings were torn down，according to sustainablebusiness．com．But that's not all---99percent of the debris（廢瓦礫） were reused to build the Olympic Park．For example，the Olympic Stadium's roof is made from 2，5.00 tons of steel tubes recycled from old gas pipelines．
As well as using recycled materials，all venues（場館）were built with green building techniques．The Olympic Stadium is the lightest one ever built，whichminimizedthe amount of steel and concrete needed．Also，the handball field has lighting pipes on the roof that reduce electricity use by 40 percent，according to sustainablebusiness．com．
The effort that London made to deal with waste also deserves praise．Water used for drinking and watering plants was from collected rainwater or recycled wastewater．In this way，about 30-40 percent less water was used in total．Waste food package were either recycled or processed and turned into renewable energy．
As one of the best connected places in Europe，London tried to solve traffic jams by encouraging the use of public transport．For example，it had trains deliver half of the building materials，instead of cars，which greatly reduced carbon emissions（排放）．
The clean anti-doping result also added to the greenness of the Games．The International Olympics Committee（IOC）said that the devices used this time were the most accurate and advanced．Only one athlete tested positive for a banned drug on the day of competing，which is why the IOC President，Jacques Rogge，has praised anti-doping efforts at the London Games．

12．Every year，thousands of young Europeans set off to explore their continent by train in the summertime．It is a necessary part of growing up and often the first time many Europeans travel without their parents．Now you too can share this adventure．
There are so many places you can not afford to miss while travaling in Europe：the Eiffel Tower in France，windmills of the Netherlands and the Colosseum in Rome．How can young people afford to visit everything they want？
The answer lies with the Eurailpass．This ticket allows a traveler unlimited journeys by rail in European countries which are members of the scheme．Ambitious Chinese travelers can buy the ticket in Beijing，Shanghai and Guangzhou．
The most popular type of Eurailpass amongst young people，according to zhaoJiaji，from China Air Service LTD，is the Rurail Selectpasses．With this you can design your own trip by selecting three，four or five neighboring countries from a total 18 nations including Liechtenstein，Monaco，Hungary and Romania．
"There is plenty of choice with this pass：in total this range offers over  400 different combinations of countries to choose from．"Said Zhao．
The Rurail Selectpass gives five to 10 travels days within a two-month period．
For example flexibility there is the Eurailpass which allows you to take trains in 17 combinations on any day you like．It is valid on a continuous basis for a period of either 15 or 21days，one，two or three months．
If you just want to travel in one or two countries to learn more about the local culture，the Eurailpass also offers two-country passes such as Spain-Portugal，F(xiàn)rance-Switzerland and Belgium-Luxemburg．Countries like Britain，F(xiàn)rance and Germany offer a kind of Eurailpass which allows unlimited train travel in their country．
Before buying a Eurailpasts，you should be aware of the best ways to save money．A second class train travel ticket is cheaper than first class； youths under 26 years old or group of two or more people traveling together can enjoy discounts．

11．Animals Can Sense Natural Disasters
Among the dead in South Asia's tsunami（海嘯）were many tourists at Sri Lanka's national wildlife park at Yala．But very few of the park's animals-elephants，buffaloes，monkeys and wild cats-appear to have died．There are theories that animals can sense natural disasters and run away to safety．
First，it's possible that the animals may have heard the quake before the tsunami hit．The underwater burst produced sound waves known as infrasound（次聲）．Humans can't hear infrasound，but many animals including dogs，elephants，tigers and pigeons can．
A second early warning sign the animals might have sensed is ground vibration（震動）．The great quake would have produced vibrational waves known as Rayleigh waves．These vibrations move through the ground like waves moving on the surface of the ocean but faster．They travel at ten times the speed of sound．The Rayleigh waves would have reached Sri Lanka hours before the water hit．Mammals，birds，insects and spiders can sense Rayleigh waves．So the animals at Yala might have felt the Rayleigh waves and then run to higher ground．
But what about humans？While we can't hear infrasound，we can feel it，although we don't necessarily know we're feeling it．We also experience Rayleigh waves by special sensors in our joints（關(guān)節(jié)），which exist just for that purpose．Sadly，it seems we don't pay attention to the information when we get it．Maybe we screen it out because there's so much going on before our eyes and in our ears．

56．Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit？D
A．Because human beings cannot hear the infrasonic sound．
B．Because the animals were staying at a higher place in the park．
C．Because the animals were able to run much faster than human beings．
D．Because the animals might have picked up the danger signals and ran away．
57．Which of the statements about"Rayleigh waves"is true？A
A．Rayleigh waves can be felt both by animals and human beings．
B．Rayleigh waves，just like infrasonic sound，can only be felt by animals．
C．Rayleigh waves are vibrational waves that usually cause quakes or tsunamis．
D．Rayleigh waves move on the ocean surface at a speed ten times that of sound waves．
58．According to the passage，which of the statement is true？B
A．We can't feel the infrasound so we can't be informed of the danger．
B．We ignore the information of tsunami's coming even though we can also get it．
C．We were so busy on our minds that we feel neither infrasound nor Rayleigh waves．
D．We can feel Rayleigh waves and infrasound so we can escape the danger like animals．

10．What's life like on a deserted island？Senator（參議員） Jeff Flake of Arizona decided to find out．
The adventurous senator took a vacation from Capitol Hill and went on a four-day Robinson Crusoe style holiday with his two teenage sons to a remote，uninhabited island in the North Pacific Ocean．
The senator and his sons，15-year-old Tanner and 13-year-old Dallin，traveled 5，200 miles from Phoenix，Arizona to the island of Biggarenn．They didn't carry any food or water．
The island is part of the Marshall Islands．It offered no basic facilities，so the Flakes had to catch and cook their own food and purify their water．Their diet was made up of coconuts，crab and fish．They captured the crab and fish themselves and cooked the food over an open fire started with a magnifying glass（放大鏡）．
The Flakes brought along a lobster（龍蝦） trap in hopes of having some delicious treats，but lost it within the first few hours after it was attacked by a shark．They also carried two pumps to remove salt from ocean water．It took them hours each night pumping for just a few gallons of fresh water．
One of the most memorable moments of the trip，the father said，was when he and his 15-year-old son were chased by sharks after spearing（叉） a fish in the ocean．
Still，it was quite an enjoyable holiday for the senator．"For a dad it was a wonderful thing．No video games around，no television，no distractions，no texting，"Flake recalled．

9．Only two countries in the advanced world provide no guarantee for paid leave from work to care for a newborn child．Last spring one at the two，Australia，gave up the bad distinction by setting up paid family leave starting in 20ll．I wasn't surprised when this didn't make the news here in the United States-we're now the only wealthy country without such a policy．
The United States does have one explicit family policy，the Family and Medical Leave Act，passed in 1993．It entitles workers to as much as 12weeks'unpaid leave for care of a newborn or dealing with a family medical problem．Despite the modesty of the benefit，the Chamber of Commerce and other business groups fought it bitterly，describing it as"government-run personnel management and a"dangerous precedent （先例）．"In fact，every step of the way，as （usually）Democratic leaders have tried to incrouce work-family balance measures into the law，business groups have been strongly opposed．
As Yale law professor Anne Alstott argues，justifying parental support depends on defining （定義）the family as a social good that in some sense，society must pay for．Parents are burdened in many ways in their lives：there is''no exit"when it comes to children．Society expects-and needs-parents to provide their children with continuity of care．And society expects-and needs-parents to persist in their roles for 18years，or longer if needed．
While most parents do this out of love，there are public punishments for not providing care．What parents do，in other words，is of deep concern to the state，for the obvious reason，that caring for children is not only morally urgent but important to the future of society．To classify parenting as a personal choice for which there is no collective responsibility is not merely to ignore the social benefits of good parenting：really，it is to steal those benefits because they accrue （累積） to the whole of society as today's children become tomorrow's citizens．In fact，by some estimates，the value of parental investments in children，investments of time and money，is equal to 20-30% of GDP．If these investments bring huge social benefits-as they clearly do-the benefits of providing more social support for the family should be that much clearer．

67．What do we learn about paid family leave from Paragraph 1？D
A．It came as a surprise when Australia adopted the policy．
B．Setting up this policy made Australia less influential．
C．It has now become a hot topic in she United States．
D．No such policy is applied in the United Slates．
68．What makes it hard to lake work-family balance measures in the States？B
A．The incompetence of the Democrats．
B．The opposition from business circles．
C．The lack of a precedent in American history．
D．The existing Family and Medical Leave Act．

A．Children need continuous care．
B．Good parenting benefits society．
C．The cost of raising children has been growing．
