The students of Class Three are going hiking for their fieldtrip. Hiking is good for people’s health. Many hikers like to hike in the countryside, forest (森林) and mountains. Just walking for fun is the first kind of hiking. Many people like to hike in the parks or just on the sidewalks.
A hike can take a few hours or weeks. For most hiking, people just need clothes and shoes that are good for the weather. At the beginning hikers should start with walks that they can do in one day. As you get stronger, you can go on overnight hikes. Later you can go longer than that. You can make your hiking last (持续) a few days or weeks.
For safety (安全), hikers should hike with someone. You should have one or two friends with you. It is also a good idea to carry a map.
Backpacking is another kind of hiking. People carry food, clothes and other things on their backs in packs. Backpackers can stay many days in the places where there is no food to buy. They carry what they need on their backs.
Now put on your hiking shoes and take a hike.

按所给词的正确形式填空

There are 　　　 (many) students in Class One than in Class Two.

Like schools in China, American schools begin in September after a long summer vacation. There are two terms in a school year. The first term is from September to January and the second is from February to June. Usually American children begin to go to school when they are five years old. Most students are seventeen or eighteen years old when they finish high school.
But unlike middle school students in China, high school students in America take only four or five subjects each term. They usually go to the same classes every day and have homework for every class. After class they do all kinds of interesting things.
After high school, many students go to college. They may go to a small or a large one. They usually have to pay a lot for their higher education. So lots of students work after school to make money for their studies.
