Do you ever find yourself getting really unhappy for almost no reason? Or suddenly feeling down without knowing why? Going from sadness to anger to joy in a matter of minutes can make many teens feel as though they're losing control. But why is the feeling so common among teens?
Maybe you're starting a new school and not able to see old friends as much. Getting good grades or wanting to be better in sports or other activities can be a concern (关注)for many teens. Being accepted by friends is important. Teens also may notice, for the first time, a sense of distance from parents and family. You may feel you want to be on your own and make your own decisions, but it can also seem a bit lonely at times.
Another important cause for mood swings is biology. When puberty begins, the body starts producing hormones（荷尔蒙）. These hormones cause physical changes in the body. But in some people, they also seem to cause emotional(情绪的)changes.
Here are some things you can do that might make those bad moods a bit easier to deal with.
Recognize you're not alone. Although not every teen experiences mood changes to the same degree, they are common.
Talk to people you trust. Friends can help each other by realizing that they're not alone in their feelings. Talking to parents is important, too. Parents can share their own experiences dealing with bad moods. Teachers are often good resources and a doctor can help to answer questions about development.
Get enough sleep. Though it can be hard to find enough time, getting enough rest is very important. Being tired can lead to more sadness.
Create. Taking part in some kinds of activities, like building something out of wood, or starting an art or music piece. Writing can help you organize and express your thoughts and feelings. Get your thoughts on paper. Do the same thing with paint, music, or other art forms. Put your feelings into your artwork.
【小题1】When puberty begins, many teens feel__________.

Do you have a vegetable garden? Have you ever watched a seed (种子) sprout (发芽), grow and fruit until it became the tomato on your plate? If you go to school in the US, there’s a good chance you have.

At the moment, nearly 20 percent of schools in the US have their own vegetable gardens that are planted and cared for by students. Next year, even more schools will have gardens and more US kids will know the pleasure of growing their own food.

Much of the growing interest in planting comes from First Lady Michelle Obama’s “Let’s Move” project, which started last year. The First Lady wants to improve children’s nutrition (营养) in the US — and she began her project by planting a garden at the White House with the help of some local kids. The kids were more interested in eating the vegetables from their garden than in eating fast food. This gave the First Lady an idea.

Because so many US kids eat breakfast and lunch at school, the food should be healthy and good. Why not let kids grow the food for their own cafeterias (食堂)? Mrs .Obama’s plan gives money to schools to start their own gardens, and more school gardens are sprouting up every day.

Students also use the information from their gardens to study science and math, and they paint pictures of their gardens in art class. Many students choose to work in the garden instead of playing on the playground during their noon break. Sound like fun? Ask your teacher if there’s room for a garden at your school, too.
