When you hear about trees cut for paper, you might think of your favorite trees in the backyard, nearby parks or wild forests being cut to pieces.

 The good news is that production and use of paper will not cause forests to disappear. Most trees used for paper come from timberlands(林地). People plant trees here for use. It usually takes 10 to 20 years for trees to grow big enough to be cut down. During that time, trees provide a home for animals and produce oxygen(氧气) for the earth. And after people cut down the big trees, they plant small ones again.

 Often, a tree is not cut down for making paper at all. People use the big part for buildings. Paper is then made from the left small part.

 We also recycle paper—People collect used paper and turn it into new products, likes boxes, newsprint and writing paper, in the factory. So it's important for us to recycle paper and reduce(减少) the amount(数量) of it in landfills(垃圾处理场).

    In fact there are lots of videos of school bullying online every year. We feel angry with the bullies and sorry for the victims in fights and blackmails. Some middle schools and primary schools in some far counties and villages are the worst-hit parts. Nearly half the victims of bullying in middle schools choose to stay silent rather than ask for help or ways to solve the problem, China Youth Daily reported.

    There is a study on junior middle school bullying made by the China Women's University. It showed that 48.9 percent of the students never asked for help after being bullied. And the study also told us 52.6 percent kept silent because they were afraid of “losing face among schoolmates”.

    The China Youth and Children Research Center made a survey of 5,864 primary and middle school percent of students suffered bullying, while 6.1 percent were often bullied by senior schoolmates.

    Cases of violence between boys and girls totaled 85 percent of all school bullying, the report said. Violence between girls accounted for as much as 32.5percent of the total. Unlike direct arguments usually seen between boys, the violence between girls more often took the form of insults, which terribly caused victims have strong feelings, it was added.

    A study published by the Beijing High People's Court showed that 68 percent of offenders attacked their schoolmates in a cruel manner and nearly 60 percent of school violence cases were caused by small matters, Legal Daily said.

    Earlier, Tang Jun of Renmin University of China told reporters that the social risks of school bullying have been given too little care. We should train our teachers to deal with school bullying, improve their skills of preventing it, and help the victim students to recover physically and mentally. At the same time, students and their parents should know the school's rules about bullying and what they should do if it happens. Second, children should be taught to stand up for themselves. They should try to solve problems by talking them out. Children should tell someone if they are being picked on. Third, parents should look for warning signs of bullying. We must pay more attention to it and try our best to solve it.

    Have you ever seen a robin(知更鸟)? Robins have dark heads and red chests.

    A good place to see robins is in your own backyard. Robins don't mind being around people. You may also see robins on lawns(草坪) or in parks. They are looking for worms and bugs to eat.

    Early in spring, robins build their nests(巢). They build them in trees. Robins hide the nests in trees so that they will be safe.

    The nests are made of grass, sticks, and mud. The mud makes everything together. The mother robin lays(产蛋) one egg a day for three or four days. She sits on them to keep them warm. The eggs are blue. After the babies come out, both the mother and father feed the babies. The young birds have spots on their chests.

Have you ever planted aloe vera(芦荟)? With long and green leaves, the plant usually grows in dry and hot places. 

Aloe vera is a very hard- working plant. It can be used to help with cuts or burns. Aloe vera also cleans the air around it. Bad air can come from the paint on the walls of some houses. Aloe vera can make the air clean again. Aloe vera is also a good plant to have in your room at night when you sleep. The plant can take in the air you breathe out and then give off the clean air that you breathe in. 

Aloe vera is popular for its long life as well. Most of the plants can live for around ten years indoors. However, if they are carefully cared for, they can live for over 20 years. Warm and dry air, lots of bright light, regular watering, and protection from pests and diseases will help them live longer. 

Growing an aloe vera plant at home is very easy! You can buy a plant at a store. Put it in a place with lots of sunlight. Water your plant during the spring, summer and autumn. If you want more aloe vera plants, you can just break off part of the plant and put it into the ground. Then it will grow again.
