Trees are useful to man（人类）in three very important ways. The first important way is that they provide man with food, wood and other products. Trees provide not only man with food, but also many animals with food. Without trees many animals could not live on the earth. It's not easy for man to live on the earth, either.

The second important way is that trees give us shade. On a hot summer day, people are eager(渴望)to have a rest under the shade of a tree after they have walked a long way. You can imagine how important the shade of a tree is to man and to animals.

The third important way is that trees help to prevent drought（干旱）and floods（洪水）. However, in many parts of the world, man has not realized the third important way. He has cut trees down in large numbers. In the end he finds that he has lost the best friends he had.

San Russell is not your average(一般的) baseball fan. He is a die-hard Boston Red Sox fan. He has a season ticket and he arranges his work schedule so he does not miss a game. San also attends game dressed in their uniform, and his car is red. He has even lost some friends by choosing to watch the Red Sox instead of going to their weddings. Is this healthy behavior?
Although Russell’s case is extreme, being a sports fan can be healthy for you. According to a study at the University of Kansan in the USA, sports fans suffer from depression less than people who are not interested in sports, fans also experience other effects from watching their team play. When their team wins a game, their own confidence and happiness increase, just like the athletes. Losing, on the other hand, always leads to some sense of disappointment.
What about die-hard fans whose team always loses? The team spirit keeps those fans from losing hope. Knowing that other fans are probably feeling the same way also helps them. In addition, there is always the hope that their team will win the next game. Russell has lost some friends because of his love for baseball and although you may think that would make him unhappy, he has made many more new friends because of his team spirit.
For Sam Russell, supporting the Red Sox is not just a hobby; it is a way of life and the secret of his happiness.
【小题1】From the reading we can infer that a die-hard fan           .

Passage 3
A smile will tell people around you that you are a kind and friendly person. However, many people don’t smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn’t have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others’ teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them.
Smiling can help you to feel more confidence and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 30 times a day, while adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now.
