Every living thing needs to reproduce(繁殖). Reproducing means creating more members of your group. In order for plants to reproduce, they have to spread their seeds(种子)to other areas. Plants have developed all kinds of ways to do this.
The simplest way is gravity(重力). Many seeds are inside of fruit. When fruit gets too heavy, it falls from a tree to the ground. Sometimes animals will pick up the fruit and drop it in another area. That helps move the seed even farther away. Apples spread this way.
Other plants use wind to spread their seeds. Dandelions(蒲公英)are a good example of this. Dandelion seeds are so light that when wind blows, it carries dandelion seeds to new places. Maple(枫树)seeds also use wind. Their seeds are connected with long, thin leaves that look like wings. When the seed falls from the tree, its “wings” help it fly farther from the tree.
Some animals help plants spread their seeds. The animals eat the seeds. While the seed is in the animal’s body, it stays whole. When the seed leaves the animal, it’s in a new place.
Ants also help spread seeds. Some seeds have a special smell that appeals to ants. The ants bring the seeds back to their home, which of course is underground. They only eat part of the seed. They leave the rest of the seed underground. After that, the seed can start growing.
1. When fruit gets heavy enough, it will fall from a tree to the ground because of gravity.
2. All plants can spread seeds by themselves.
3. Wind helps apple and dandelion seeds to fly farther to new places.
4. Some animals and ants eat seeds, and it is helpful for seeds to spread.
5. The passage is mainly about the relationship between animals and plants.
When you feel sad, tears will come down from your eyes. When you are happy, especially when you laugh hard, tears will also come down from your eyes. But tears have a more important job than showing your feelings.
Tears keep your eyes clean and healthy. They wash away dirt and germs just like bath. Your eyes also need tears to keep them wet. And eyes must be wet so that they can move smoothly. Your eyes are busy looking here and there all day long. They move quickly from one thing to another. If you didn’t have tears, your eyes couldn’t move, and soon you would be blind.

Trees are useful to man in three important ways.
The first important way is that they provide(提供) man with food, wood and the 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(阴凉). On a hot summer day, people are eager(渴望) to have a rest under the tree after they have a long walk. You can imagine how important the shade of a tree is to man and animals.
The third important way is that trees help to prevent droughts and floods(防止干旱和洪水). However, in many parts of the world, man hasn’t realized the third way. They were cutting trees down in large numbers. In the end they find that they have lost the best friends they had.

We have a two-day holiday every week. We don’t have any lessons on Saturdays or Sundays, so every weekend I have a good time.
On weekends, I like taking a trip. I sometimes go to the country with my classmates by bus to breathe(呼吸)the fresh air, watch the green hills and the blue sea, and walk in the beauty of the countryside. Sometimes I go for a picnic in the open air with my friends by bike. There we draw many pictures and take photos. Sometimes I go to visit a place of interest with my parents by car.
Sometimes on Saturdays, I take a long trip with my parents. We don’t go home at night and make a fire on the hill. We sit around it, singing and dancing happily. If we feel tired, we get together, look at the stars and chat for a long time, and then sleep for a few hours.
My weekends are always full of interest and happiness.
