Travelling can be a way to gain life experiences，especially during Spring Break—a week long school vacation in the United States. But what if you’re a student and don’t have enough money for a trip? Don’t worry. Here are some useful suggestions.
Save：This probably is the most important preparation for travelling. Cut expenses to fatten_your_wallet so you will have more choices about where to go and how to get there.
Plan ahead：Don’t wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security and savings.
Do your homework：No matter where you go，research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.
Plan sensibly：Write down what you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.
Travel in groups：Find someone who is interested in visiting the same place. By travelling with others you can share costs and experiences.
Work as you go：Need more money to support your trip? Look for work in the places you visit.
Go off the beaten path：Tourist cities may be expensive. You may want to rethink your trip and go to a lesser－known area. Smaller towns can have many interesting activities and sights.
Pack necessary things：The most important things to take are not always clothes. Remember medicine in case you get sick and snacks in case you cannot find a cheap restaurant.
Use the Internet：The Net can help to save money. Some useful websites include www.Travelocity.com，www. bargains－lowestfare.com and www.economictravel.com.
By planning sensibly，even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.

数学奥赛暑假天天练南京大学出版社系列答案
南大教辅抢先起跑暑假衔接教程南京大学出版社系列答案Before going outside in the morning, many of us check a window thermometer(温度计)for the temperature. This helps us decide what to wear. _____76____. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.
Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.
Both systems use the freezing and boiling points of water as their guide._____77_____ .
The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube._____78______.
First. Take a clear glass juice bottle that has a cap ; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.
______79______.
Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.
______80____.
As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.
|
A．We use and depend on thermometers to measure the temperature of many other things in our daily lives. |
|
B．Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled. |
|
C．Now that you know this rule you can make a thermometer of your own that will work. |
|
D．The water will rise in the straw. As the temperature of the air goes up, the water will |
expand and rise even higher.
E．They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.
F．Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal把..粘住) them together.
G．People use thermometers which are made by themselves when travelling around the
world.
