When a man-eater such as this is discovered, people are much afraid and they have to stop working in the fields. There are many ways to put an end to such dangerous animals. One way is that some men with long guns sit on elephants while other men drive the tiger towards them. Another way is for a hunter to sit on a tree near the place where a tiger has eaten somebody. If the tiger returns for another meal, the hunter will kill it in the hiding place. A goat may be tied to the tree for the tiger to kill.

There are several ways you can find out about the countries and places you wish to visit. You can talk to friends who have traveled to the places, you can go and see a colour film
about them, or you can read a travel book.
It seems that there are three kinds of travel books. The first are those that give a personal, subjective(主观的) idea of travels which their writer has got himself. These books can be useful if the writers share their traveling experiences with others. The second kind are those books which give objective(客观的) information of things to be done and seen. If a cultured person has written such a book about the facts of a place, then it is more useful. The third kind are those books which are called “a guide” to some place or other. If they are good, they will describe and explain the place in detail. Like the first kind , they can be interesting and exciting, but their main purpose is to help the reader plan his travel in the most practical way.
Whatever kind of travel book you choose, you must make sure that the book does not describe everything as interesting, exciting or fantastic. You must also keep an open eyes on its date of publication(出版) because travel is very practical matter and many things change quickly in the 21st century. Finally, you should make sure that it’s easy to fin d the useful information for you travel.
