汽车突然熄火了，我怎么也发动不起来。

我对这个结果大为惊异，以至无法相信自己的眼睛。

与大部分人认为的相反，很多猫并不喜欢牛奶。

由于天气不好，今天上午的航班将延误。

I think nothing  travelling.

You may imagine their at finding the room empty .

Getting around in Canada is fairly easy. Most cities have urban transportation systems, including buses, streetcars, and trains, and some of the larger cities also have subways.

You can board these systems at regular stops along their routes. Some let you pay with cash; others require tickets. If you don't have a ticket for the bus, you must pay with the right amount of money. This is because the driver does not carry any change. Once you get settled, you may want to buy a monthly pass or a package of tickets to save money. You can buy subway tickets at the subway station.

If you have to take several buses or the subway for a single trip, you do not need to pay any money each time. Simply ask the driver for a transfer, or pick one up from the machines on the subway platform.

If you are not sure where to board the bus or the streetcar, just ask someone, or follow the crowd. It's usually at the front of the bus, where you show your pass to the driver. When using public transportation, Canadians line up. First come, first served, is a common approach to many activities in Canada.

Maps of routes and schedules are usually available from the public transit company in your area, and there may also be a telephone information line. You may want to ask someone for the name of the transit company where you live, and then look it up in your telephone book.

Back in April 1939 and armed with $5,000 provided by the Rockefeller Foundation, professor Frank Cyr at Teachers College, Columbia University took a tour of ten states to make the research about school transportation problems. What he found was that many students had no dependable way to get to school and the ones who did often travelled in unsafe buses in the over 100,000 school areas.

Seeing a need to fix this problem, Cyr organised a meeting—one that would change the future of school buses forever. School officials and transportation experts met to set much-needed standards for buses, including those for colour, height and width as well as safety rules that hadn't been set before or that were different in every state.

There were many different bus colours in the US before this meeting; several areas even planned to have red, white and blue buses as a way of encouraging students to love their country. Cyr presented his new choice to education officials, a reported "50 shades( 色度) changing from lemon yellow to deep orange red". The matter was settled quickly. Yellow, or "National School Bus Glossy Yellow", was chosen because it was quite striking, making the school bus easy to be seen. Besides, it made the bold(黑体的), black writing on the side of each bus clear. (The bold, black writing gives information about each school area, telling students which school bus they could take during early morning and late afternoon hours.) Thirty-five states made the changes quickly, and every state took them on

board by 1974.

Being recognised as the "father of the yellow school bus", Frank Cyr has surely influenced your life if you ever rode a school bus or saw that noticeable colour pulling up to your stop on a dusky morning.

Do you think about overseas trip but worry that you might make a less-than-worthy choice because you can't afford to visit all the places on your wish list before you make your final decision? However, little money doesn't mean you have to stay at home.

Hug the simple joy with travel.  Or even climb to the top of a hill and watch the sun set over the ocean. The simple joy of being in a new place is just a matter of going some place new. No tour package required.

 People need fresh air, exercise, creative excitement, a new relationship and so on. All of these things are simple to get and most of them are free. For fresh air, go outside. For exercise, go out for a jog. For creative excitement, go somewhere new, such as a neighbourhood near your accommodation or just a local market. For a new relationship, make friends with the locals. And you can get a better understanding of the native civilization.

Go slowly. If you live in New York and want to take a 2-week vacation to Africa, it will be very tough to travel with low cost. Time is not money.  Instead of buying a plane ticket, take a train or bus, or just hop your bike and ride away from the town. The slower you travel, the less money you will spend.

Try to get your accommodation for free or next-to-nothing. Find kind souls around the world who agree to offer an extra bedroom, sofa, or a corner of the floor to travelers in exchange for the same kindness when they visit your town. This plan involves trading homes for an agreed-on amount of time.

A. Time can be free.

B. Keep your needs to the lowest degree.

C. Walk on the streets of a city and chat with a local.

D. Things like air and water are much cheaper once you get outside.

E. With a bit of creativity and some tricks, you can travel the world cheaply.

F. If you can do what needs to be done around the house, just stay inside for free.

G. It works best if your home is in a place someone wants to visit during your vacations.
