【简答题】
These days when you go on vacation, you spend most of your money just getting there. Travel is expensive, but don't stay home only because you are short of money! Here is some advice: * Travel during off-season if possible. Flights and hotels are very cheaper when tourism is low. * Choose a hotel that's a little farther from popular attractions. If you're staying several days, check out prices on vacation homes — it can end up being cheaper than a hotel. * Take public traffic, such as buses or subway, instead of taking a taxi. * Plan your meals, and eat like locals. Don't waste money at expensive hotel restaurants or fast-food chains. Depending on where you stay, it may be cheaper to make food on your own. * Check online for special discount (折扣) — if you're a student, the old or the parents traveling with children, you could get discounts! A little research could save you a lot of money. Whether you're backpacking alone or going on a family vacation, your trip doesn't have to break the bank. The key is to plan ahead and write down what you spend. Then put the money you save toward your next trip! 小题1:Is travel expensive now? 小题2:How many suggestions are given to save money? 小题3:Which is cheaper, staying at a hotel or a vacation home? 小题4:Who could get discounts? 小题5:What is the passage mainly about?
