There are many ways to find a job. It can be as easy as walking into a neighborhood store to look at its announcement board. Local stores often have areas where people can put small signs telling what kind of service they need or can provide. Such services include caring for children or cleaning houses.

Or, job searchers can look in the newspaper. Local newspapers have employment announcements placed by companies seeking workers.

Another popular tool for finding jobs is the Internet. For example, people in four hundred and fifty cities around the world can use the Craigslist Web site to buy objects, meet people or find a job. Craigslist says that it receives two million new job listings each month.

Of course, looking for a job requires knowing what kind of work you want to do. For example, there is a book called “What Color is Your Parachute ?” by Richard Bolles. This book has been helping people choose a career since it was first published in nineteen seventy.

高一英语单项填空简单题查看答案及解析

There are two ways to save money traveling. The first way is to get the best deals on the specific things you want. There is a limitation to this type of approach (途径，方法) though. If you find the lowest price on the best hotel in Honolulu at the height of the season, you will save money, but still have a very expensive vacation. Trying to get exactly what you want will generally be an expensive proposition, in travel and in life.

The other approach is to be a true opportunist. This will be difficult for some of you, and entirely unacceptable to others. Nonetheless (尽管如此)，the travelers who get to travel the most, go to the widest variety of places, learn the most and do the most, are the opportunists. This will be true until you are so wealthy that you have no monetary (货币的；钱的)limits.

The first time I went to Ecuador, I went there because it was cheap. If it wasn’t, I would have had a great time—somewhere else. The trip lasted a month, and cost $1045, which included airfare and even the $130 fee for a guide to take me to the top or glacier (冰川) covered Mount Chimborazo.

I cut the cost by taking a bus from my home in Michigan to Miami, and back again when I returned from Ecuador. The round-trip ticket cost $158. The round-trip flight to Quito from Miami was only $256, because it was a courier (信使，通讯员) flight, which meant I signed for some luggage(car parts), and  could only take carry-on luggage.

Never did I feel deprived, or bored. I had a great time, eating wherever it was cheap and clean, doing all sorts of inexpensive, but interesting things, and traveling across the country to climb Chimborazo. I also met and fell in love with my wife Ana.

Being an opportunist means you’ll have just as much variety, and probably almost everything you want—eventually. You just have to stop trying to get exactly what you want exactly when you want it. If the guide that took me up Chimborazo hadn’t dropped his price from $200 to $130, I would have spent $2 for a bus and gone hiking on EI Altar, another great Andean mountain. That would have left me with enough money for several other minor adventures.

1.The underlined phrase “the best deals” in the first paragraph probably refers to ______.

2.The return tickets from his hometown to Quito cost the author ______.

3.The last paragraph was to tell us how to ______.

4.It’s suggested that the author _____.

5.Which of the following can serve as the best title of the passage?

高一英语阅读理解困难题查看答案及解析

Why do people travel? There are many reasons one can think of when asked questions like this.

To travel far enough to meet yourself

Sometimes you find yourself in the middle of nowhere. 1. You find out your abilities. When you are offered a different lifestyle, you can find out what you are made of. The farther you go from your home, the nearer you come to your true self.

2.

If you look back at all the amazing memories of your life, you will realize that most of them were out of your comfort zone. Travelling is dangerous, full of life threatening possibilities and will not always be comfortable, but at the same time, it gives irreplaceable memories.

To slow down and relax

A wise man once said that never get so busy making a living that you forget to make a life. Money is worth nothing if you cannot spend it on a little adventure. While we are deeply involved in making money, we forget that time is going through our fingers. 3. The feeling of being away from your workplace is pure happiness. The feeling of not having to worry about the never ending piles of files is pure joy. 4.

To celebrate life

Life is short and the world is wide. One day you might wake up and realize that you don’t have time to do everything that you have always wanted to do, anymore. Once in a while, make time to appreciate the fact that you are alive, young, free and healthy. 5.

A. To become a storyteller.

B. Travelling lets you discover yourself.

C. To break through your comfort zone.

D. So, go travelling to celebrate life itself.

E. You can relate to the world and connect to others.

F. And the feeling of being away from your boss for a few days is pure pleasure.

G. Escape life for a little while because experience is far more valuable than money.

There are two methods by which hydrogen(氢)can be used to power cars.The first way is to use hydrogen to drive the engine，in much the same manner as many cars use gas.The second method is to use the reaction of hydrogen with oxygen in a battery(电池).

The dream of producing hydrogen for the car from water while driving is a long way off，so we are still at the period of batteries and filling the tank with hydrogen gas.This is the most difficult thing for car users and producers.There are only sixteen hydrogen filling stations in Los Angeles and none in 99% of other cities worldwide.

Indeed，some of the big name automobile producers have pulled out of the race to put the first practical hydrogen car on the streets.Ford and GM have announced that they are pulling out in America and so has Renault in France.

However，the Japanese companies are going on with it.In fact，Honda introduced its first hydrogen fuel car in 1999.They are now working on the second­generation hydrogen cars known as the FCX Clarity.Guess where you can buy these cars？There is only one city in the world.Yes，Los Angeles，because of its filling stations.

Honda thinks that they could go into full­scale production of the FCX Clarity by 2020，if the world is prepared for them by then.Hyundai has on­going plans to make hydrogen fuel cars and says that they will be produced in 2012.Daimler also says that they would be producing 100,000 hydrogen fuel cars in 2012－2013.

Then there are hydrogen powered buses in several European cities including Amsterdam，Barcelona，Hamburg，London，Luxembourg and Madrid.Lotus，the maker of London taxis，has announced that they want to produce some hydrogen powered taxis in time for the London Olympics.

So the hydrogen vehicles(交通工具)are out there and the numbers will be growing fairly soon.However，getting fuel is not the only difficulty for the average motorist.

1.Which of the following things may take the longest to come true?

A. Using the reaction of hydrogen with oxygen in batteries to power cars.

B. Using water to produce hydrogen for cars while driving.

C. Hyundai's developing hydrogen fuel cars.

D. Developing hydrogen powered taxis.

2.Which of the following statements about hydrogen powered vehicles is TRUE?

A. Hydrogen powered cars were not introduced to the public until the 21st century.

B. Hydrogen powered buses can only be seen in America right now.

C. Hydrogen powered taxis produced by Lotus will be used in America soon.

D. Hydrogen powered vehicles are likely to increase in the number soon.

3.The writer wrote this passage mainly to________.

A. tell us the history of hydrogen powered vehicles

B. tell us the present­day situation of hydrogen powered vehicles

C. introduce some Japanese car producers to us

D. introduce several European cities that are using hydrogen powered vehicles
