   Back to the time when a newspaper was the main way people got their news, a bike was the best way to make some money before or after school for a kid. Those days are gone，with newspapers delivered（递送）by car and print competing with digital subscriptions（订阅）But the ability to make some extra money still exists if you have a bike.

1.Bike Messenger

Biking up and down the hilly streets of San Francisco to deliver documents between businesses on a bike can be difficult, but according to Salary Expert, the average yearly salary for a bike messenger is $24,966, and the average hourly rate is $12.

2.Bike Tour Guide

If you’re an expert on where to find interesting places in your city, then leading tourists to the best restaurants and landmarks can be a fun way to make money outdoors on weekends or whenever you’re free.

3.Pedicab（三轮车）Driver

You can work for a pedicab company in a city full of tourists. The pay can be up to $500 on a busy night, says one driver. This seasonal job can be much more enjoyable than helping at a law firm.

4.Bicycle Mover

The Swedish company MoveByBike is only in Sweden, but you can start your own bike moving company. It uses bike trailers（拖车）to move furniture and other belongings for people who aren’t moving far. This can be convenient for people to move a few miles within a city. If you don’t have a bike trailer, you can make one yourself, though a large one for furniture may be too much work to do on your own.

A bike is a piece of transportation that can get you somewhere fast. Whatever service you provide on a bike, start by advertising it as a green alternative to other methods of getting something.

【小题1】Why does the author say the days of delivering newspapers by bike are gone?

B．Digital newspapers have replaced traditional newspapers.

C．Newspapers are delivered by car and there’re digital papers.

D．It’s dangerous to do so because of the busy traffic in the street.

【小题2】What will someone do as a bike messenger?

A．Deliver documents by bike between businesses.

B．Help people get a high salary from work.

C．Show visitors around places of interest.

D．Help people to transport their belongings to a new place.

【小题3】What can be known about pedicab drivers?

A．They can offer help at a law firm when they’re free.

B．They can do this job only in certain seasons.

C．They can make a living only in tourist attractions.

D．Most of them act as tour guides for a part-time job.

【小题4】What does the underlined word “it” in the last paragraph refer to?

D．The bike you’ll use.

   Sometimes you have to visit your friends or relatives without much time for making preparations. Your only problem seems to be what to do with your pet. You can either leave it at your home or bring it with you. Traveling with your pet is easier than you think.

You can bring your pet with you by using air travel services. These services fall into two groups, in a cabin（客舱）and cargo. In-cabin pets must be small enough to fit into a carrier that will be placed under the seat in front of you. Pets too large to fit comfortably into a carrier must travel in a cargo. Cargo holds are heated or cooled, just like the passenger area.

Pet passengers require a reservation（预约）, whether traveling in a cabin or cargo. Airlines have rules about the number of pets they will carry in order to ensure travel safety for all. So making your pet's reservation as you buy your ticket is a good idea. Of course, you should pay extra charges for both in-cabin and in-cargo pets.

Buy a health certificate from your vet（兽医）. A health certificate is only good for ten days, so if your visit is longer than that, you will have to buy another health certificate for the return trip.

As mentioned, your in-cabin pet will need a carrier. These soft-sided carriers come in several sizes, so buy or borrow one that allows your pet plenty of room. Some of these can be bought with wheels to make transport through the airport easier; these also reduce "pet space" under the airplane seat. But pets traveling in a cargo need hard-sided carriers.

【小题1】According to the passage, you travel with your pets most probably because ________.

A．travel time is limited

B．it's quite easy to do so

C．you don't have a careful plan before the journey

D．pets can bring you a lot of pleasure during the journey

【小题2】Why should you make a reservation for your pet?

A．It is difficult to find a place for pets.

B．Pets are forbidden on planes sometimes.

C．It's not easy to get in-cabin services for big pets.

D．There's a limit to the number of pets on planes.

【小题3】What can we learn from the last paragraph？

A．We should try to reduce "pet space".

B．We'd better buy large carriers for pets.

C．Pets in a cargo also need soft-sided carriers.

D．We should choose proper carriers for our pets.

【小题4】What's the passage mainly about？

A．Airline services for pets.

B．Different carriers for pets on planes.

C．How to travel with your pets by plane.

D．What to do with your pet when you're away.

   With an improved economy，many travelers have been buying first or business class seats，leaving fewer for upgrades（升级）.Here are some strategies for getting a free upgrade.

1. Fly a lot.

This is the most common way to earn a free upgrade. Most airlines reserve some spaces for travelers who fly at least 5，000 miles per year. Five years ago，this meant half or more of domestic（国内的）first class travelers sat up front for free. But now，airlines are selling more high-price seats，so on popular routes it is not unusual for more than 20 travelers to compete for one or two upgrades. But on routes with fewer business class travelers，free upgrades remain more plentiful.

2. Use miles.

If you're not a frequent traveler but still have some miles to fly，you may be able to use them for an upgrade. Be careful，though，as many airlines now ask not just for miles but also a cash co-pay. One example: on flights to Europe，American Airlines charges 5，000 miles，plus $110，for a one-way upgrade from discounted economy class to business class. For most domestic upgrades，American Airlines wants 15，000 miles plus $ 75.

3. Get lucky.

Sometimes airlines overbook coach（经济舱），and a few travelers get no seats. Agents try to ensure the airline's most loyal travelers get the nod（被选中）. Agents usually have some flexibility to make sure the plane is full and takes off on time. So it's the easiest way for them to do it-they might upgrade someone else out of order.

4. Save a life.

Flight attendants don't usually upgrade passengers, even when empty seats remain. Doctors and nurses who answer an emergency call are sometimes an exception. If they comfort a passenger, flight attendants might allow them to sit in business or first class for the rest of the flight.

【小题1】What might be the main topic of the passage?

A．The ways to get upgraded on a plane.

B．How to get on the flight safely and on time.

C．The best ways to get free flight tickets.

D．How to save a life on a plane quickly.

【小题2】Who can have the chance to get a free upgrade?

A．The person who always obeys the rules on the flight.

B．The person who doesn't have to look after a patient.

C．The person who is a friend of the flight attendants.

D．The person who flies a lot and has a long flying distance.

【小题3】Why might medical personnel be allowed to sit in business or first class sometimes?

A．Because they would like to talk with flight attendants kindly.

B．Because they want to have a better rest after a long journey.

C．Because they need to treat a passenger who is in emergent condition.

D．Because they are tired of staying with common passengers.

【小题4】Where can we find the passage?

A．A life guide.	B．A travel guide.
C．A shopping guide.	D．A pilot guide.

   Driving to the airport in the early morning, I felt excited. Although I was heading abroad for my first time alone, I felt cheerful and enthusiastic. I was spending the summer in Paris.

While looking for more interesting things to do besides sleeping and eating, I found programs for learning languages abroad, and jumped at the chance to study French in this city known for its art, fashion, food, and culture. As I arrived at the airport where I would leave my family, I still felt only great happiness. I excitedly made my way through security, leaving my loved ones behind.

My connecting flight was in Frankfurt, Germany, 14 hours from Denver. Sitting in a crowded plane watching bad movies couldn’t dampen my excitement. When the woman next to me asked me where I was going, I happily answered and was pleased to note a tone of jealousy in her response.

But when I arrived in Frankfurt, fear and anxiety began to set in. Being in an enormous, busy building in a country where I couldn’t speak the language was frightening, but as I found my way, I gained confidence. When I boarded the second plane and discovered that the flight was less than an hour, I was filled with excitement as I thought of how I would manage in a country with a new language.

When I stepped on the ground of Pairs for the first time, I was extremely happy and excited. I gathered my bags and joined the crowd of people waiting for friends and family. I quickly had my first experience trying to communicate in a language that I had only practiced in school. As I left the airport, I looked for familiar monuments I had read about, but the landscape looked very- ordinary. Then, with one sharp turn, the Eiffel Tower came into view, and I was finally in Pairs.
