You might be surprised to know that bicycles have existed for about two hundred years, but no one is sure who first made this popular two-wheeled machine.
1.The front wheel was much bigger than the back one, and also there weren't any pedals (踏板), Riders had to move themselves forward by pushing their feet against the ground.
2. In 1879 an Englishman had the idea of connecting them to the back wheel with a chain. Gears(齿轮), which made things much easier for those cycling uphill, first appeared in the 1890s.
There are now about one billion bicycles in the world.3.They have to compete with cars on the streets of all the world' s cities, and the two forms of transport don' t always mix well. In London in 2005, for example, over 300 cyclists were either killed or seriously hurt in accidents.
Because bicycles are much more environmentally friendly than cars, now many governments encourage people to ride rather than drive.4.The number of yearly journeys made by bicycle in London has increased 50% over the last five years.
However, although one in three British people owns a bicycle, they still don't use them nearly as much as they could 5..
It is hoped that more people will rely on bicycles to move around. The reasons are obvious--cycling helps to protect the environment, keep us fit, and it is often not only cheaper but also quicker than travelling by car in many cases.
A.Pedals finally arrived in the 1840s.
B.Cycling is on the rise in the United Kingdom.
C.Bicycles are used for only 2 % of journeys in the UK.
D.The first person who made a bicycle was an Englishman.
E.The number of bicycles is twice more than that of cars.
F.The early models didn't look much like the bicycles of today.
G.Cycling helps improve people's health.
Your dog is as smart as any two year old, according to a new study. Dogs bring much happiness to their owners, and even improve human health. Most two-year-olds keep us busy in life - an important part of living a long and happy life. According to Stanley Coren, Ph.D.of the University of British Columbia, our dogs are smarter than we thought.
Dr. Coren reviewed many studies to find out that dogs are as smart as 2 to 2.5-year-olds. Forget about one word orders - according to Coren, the smartest dogs can learn up to 250 words. Most dogs understand an average of 165 words. “The upper limit of dogs, ability to learn language is partly based on a study of a Border Collie named Rico who showed knowledge of 200 spoken words，and ‘fast-track learning,’ which scientists believed to be found only in humans and language-learning apes (猿).”
Dogs are also great at tricking. During play, they have the ability to trick humans and other dogs in order to get treats. “And they are nearly as successful in tricking humans as humans are in tricking dogs,” says Coren.
Dogs can also count to four or five, which might explain how they know when their toys are missing. Coren explains, “Their astonishing flashes of smartness and creativity are reminders that they may not be Einsteins, but are sure closer to humans than we thought.”
Animals can do much to keep us happy, healthy, and protect us from harm. Stories of dog heroes can be found using a simple Internet search. Pets teach us sense of duty, keep us from loneliness,and can help with treatment of the disabled.

While car sharing is a concept that’s catching on, old-fashioned carpooling where a group of people take turns driving each other to work has always faced a resistance (抗拒）. In a study on traffic problems by ABC News, 84% of those who drive to work say that they still do it alone. More than half of those lone riders insist that carpooling is just too inconvenient, and 18% say they simply don’t know anyone to share a ride with.
Now technology makes carpooling easier and more fun. NuRide, a company provided an online carpooling service last year, offers daily travelers in the Washington area not just a web-based list of would-be carpoolers but also a way to arrange a trip online. Here，s how it works: rider seekers enter the positions where their trip will begin and end, the time they want to leave and if they’re willing to drive or just ride in someone else’s car. The website’s search engine then looks for matches and makes lists of the names of traveling companions, along with the car model and the exact time and place to meet for each trip. People who want to share the ride can show their interest in joining in online and then meet their car mates when it’s time to go.
NuRide users aren’t riding with total strangers. They are required to provide the name of their employer and a work e-mail address，both of which need to be checked before being listed on the website.
To attract users, NuRide offers a frequent rider prize: anyone who shares a ride gets a $1 credit. So far, 2, 300 people have signed up. NuRide GEO Rick Steele said that more than 50, 000 rides have been arranged on the website, resulting in 1.4 million fewer miles driven and 650 fewer tons of automobile emissions (排放).

In my time here at Carleton College, I’ve picked up many valuable pieces of advice from others, and have come up with a few of my own. With my time here drawing to a close, here’s two of the most valuable ones I wish I had known as a freshman .
First, don’t expect to join all the clubs here. Taking part in them is good, but the workload here is too heavy and time with your friends is too limited to devote yourself to a million and one clubs. Find a couple of things you dig, and you’ll find yourself much happier than if you had spent your time joining every single organization that sounds somewhat interesting to you. Also, don’t always think of your free time in terms of organizations you can join. Getting really good at something - an instrument, creative writing, cooking - is just as good a use of your free time, even if it might never be taken into any resume(简历).
Second, when Socrates said “Know Yourself”, he was talking about your sleep schedule. You can fool yourself into thinking that an 8:30 a. m. class in the winter is the perfect way to get your day started, but you soon may find yourself emailing the teacher with excuses for being absent. Scheduling all your classes afternoon is sometimes equally deadly; you might just end up going out the night before knowing you can safely sleep in. I’ve found that the way to take classes is to load them in the middle of the day; nothing before 9:50 a. m., nothing after 3:10 p. m.
1.Who is probably the author of the text?
A.A school headmaster. B.A graduating student.
C.A university teacher. D.A freshman at Carleton.
2.Which of the following can replace the underlined word“dig”in paragraph 2?

3.What does the author suggest doing in one's free time at college?
A.Getting apart-time job.
B.Join clubs that seem interesting.
C.Take up a few hobbies.
D.Prepare a resume as early as possible.
4.What is the best t me for taking classes according to the author?
A.In the evening. B.In the afternoon.
C.From8：30a.m.to9：50a.m.. D.From9：50a.m.to3：10p.m..
