Are you dreaming of taking a trip on your own Here is some advice on how to make your once-in-a-lifetime journey and how to stay safe when you get there.
Before you begin to look at places, activities and plane tickets, you must set a budget. When you search through the websites about travelling, it can be so easy to add another week here or there, or choose an extra activity. Setting a budget can avoid creating a huge bill, which starts very small.
With so many countries on this planet it is difficult to decide where to go. By narrowing down your search to voluntary work or a relaxing holiday, you can save a lot of time looking through websites.
After deciding where to go, you need to research the country. Find out when each season is. It would be disappointing if you were taking part in an outdoor-based activity and it rained most days. Look into medical information, as you may need certain medicine for certain countries. Above all, make sure you can afford to go to this country and take part in the activities you have dreamt about. Don’t raise your hopes too high before you know for certain it is within your budget.
By carrying a credit (信用) card with you at all times it is possible to stop yourself getting lost. Mobile phones are very important as well. However, do not depend completely on them, since electronic machines can break without warning. Therefore, always carry a list of emergency (紧急情况) phone numbers, names and addresses. Finally, learn a little of the language. Do not expect that the people there speak your own language. After all, you are in their country.
From the text, we can know that ______.

A:travelling in a foreign country costs a lot B:deciding on where to go is an easy job C:a volunteer can help you choose where to go D:you need to know what the weather of the county you’ll travel is like

Imagine that you are in hospital, waiting to have an operation. It is time to go to the theatre; the anesthetist approaches you and speaks. But instead of the reassuring words" I’m just going to give you something to send you off to sleep", you hear: "Let me take you on a trip towards death". Terrifying Maybe, but that is what having a general anesthetic is all about. "If you give a small amount of an anesthetic drug, it won’ t have any effect. If you give more, it will put the patient off to sleep, but if you give more still it can kill the patient."
In a modem hospital, before you are given an anesthetic, an anesthetist asks you a number of questions to decide which drugs to use. Most importantly, they check the state of your heart and lungs and ask if you have asthma, angina or have ever had a heart attack. They want to know about any drugs you are taking, so that they do not give you an anesthetic that reacts badly with them, and they will also find out if you have any allergies.
As well as putting you to sleep, the anesthetist is also responsible for controlling your pain. Then how can the anesthetist tell that they have put their patients far enough under Mostly, by experience. There is no such thing as an awareness monitor, though all the patient’s body functions, such as heart rate, gases going in and out and oxygen levels in the blood, are monitored. If the anesthetic is not deep enough and the patient becomes "light’, the monitors should tell the anesthetist that something is wrong long before the patient becomes aware. This is why the anesthetist watches the patient carefully throughout the operation. At the end of your operation, the anesthetic is mined off.
It might seem surprising that the anesthetist is often the unsung hero of the operating thestre. Many people, including some nursing staff, do not realize that the anesthetist first has to qualify as a doctor. They then take three further examinations to qualify as anesthetists because of the number of things they have to take into account when carrying out their work
They do not simply need to know about the drugs they use; they must also know about all the other drugs on the market so that they can avoid dangerous interactions. They have to keep abreast of any new surgical technique, to make sure they give an appropriate anesthetic for any operation.
The "journey towards death" has come a long way. But one fascinating fact remains: whether it is ether or a complex cocktail being used to "put someone to sleep": no one yet knows exactly how anesthetics work.
An anesthetist should be present throughout the operation, in case______.

A:the patient might die B:a surgeon might need the anesthetist to give some medicine to calm him down C:the patient hadn’t been given an anesthetic deep enough D:the anesthetist didn’t know the process of the operation
