Recent research from the Pew Internet Project suggests that 90% of Americans aged from 12 to 17 use the Internet, and 51% of those teens use social networks. However, there are many possible problems with social networking sites and the teenagers who use them.

Apart from the social advantages, social networking sites can be used to record school research, develop artistic talents and experiment with other forms of subject creation. They provide a way to communicate with others who share the same interests and to get helpful advice on ongoing projects.
Along with these advantages come some dangers. For example, most social networking sites are open to all, especially MySpace, which is the most popular social network among teens in America. It means that they could be put in unpleasant and frightening situations.
A greater danger is that teens may become objects of the people with secret purposes. The secrecy of some social networking sites makes it easy for dangerous people to find young teens and invite them into dangerous conversations. It's easy for them to pretend as teens and draw children into dangerous real-world communication as well. Then further hurt might be on its way.
Another danger is identity stealing, which can happen when teens share too much information about their names, dates of birth and locations.
Therefore, it's very important to make sure teens are safe when they use social networks.
Many of the same rules that work for online chat work for these sites:
※Don't use your real name.
※ Don't give out personal information to people you don't know. A last name and a town are enough for a bad guy to find where you are.
※ Don't believe that people are who they say to be.
※ Immediately end any communication that makes you uncomfortable and report it to a parent.
Only if you are sure of your safety, can you enjoy the fun brought by social networking. Besides, trying to deal with all problems on your own can lead to terrible results. Remember, asking your parents or school officials for help doesn't mean you are unable to do anything but wiser than many others.

Spiders are not insects as many people believe. They belong to a class of animals called arachnids(蛛形纲动物). Spiders have eight eyes, four pairs of legs, and can grow a new leg if they lose one. A spider's body is divided into two sections: the abdomen(腹部) and the thorax(胸部).The legs, eyes, and mouthparts are in the thorax section.

Most spiders have poison glands(毒腺)and sharp teeth. They use their sharp teeth to force poison into the insects they catch for food. This poison can make an insect lose the ability to move, and the helpless insect is then devoured by the spider.

Spiders usually have silk glands under their abdomen. They produce a liquid(液体)that is thicker than water from their glands. When the liquid comes into the air, it dries into silk. Many spiders use this silk to form webs to catch insects and to make cocoons(茧)that protect their eggs. This amazing silk is also used to create lines that spiders hang onto as they travel to new areas.

Spiders live in almost everywhere on earth. The only places where there are no spiders are the coldest places, the highest mountains and the seas.

      Growing mushrooms(蘑菇) is probably the easiest thing you can do even if you are new to mushroom growing. It is becoming more common because restaurants are starting to create more dishes that include mushrooms.
      Mushroom growing is easy. To start, you need to have a space where you are going to grow these mushrooms. It does not have to be a huge space but just enough for you to grow as many mushrooms as you need. When you have found the space perfect for you, you can start researching what kind of mushrooms you want to grow. There are a lot of mushrooms to choose from and not all of them are suitable to eat.
     When you decide what kind of mushrooms you want to grow, you can start getting ready to plant the mushrooms. Sometimes you may want to hire some workers to help if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to have a business by yourself can be stressful. If you don't have enough time to spend taking care of everything yourself, dome helpers may be the best choice.
      After you have started the mushroom growing, you should regularly check that your mushrooms grow properly and that they are not being attacked by any pesticides(农药) or any other animals or something that could be dangerous to them. That is the worst part of mushroom developing. Protect your mushroom farm well with a fence(围栏) or a gate so that only you and your workers can get in and out.
     Mushroom growing is not difficult and it is easy to get stared in the world of farming. You will soon possibly be able to provide some of the great cooks of the world with high quality mushrooms that will be enjoyed by thousands of people all over the world.

It just hadn't been a very good week. On Tuesday, Sam's father lost his job. Then on Wednesday, Sam's mother said that the rent(房租) of their apartment was going up. Now it was Friday, and Sam received an invitation from Rosa to her birthday party.

Sam knew Rosa from Adventure Club. He knew he would enjoy Rosa's party, but he didn't want to go without a gift. What could he possibly buy her with the little bit of money he had? Sam knew he couldn't ask Mom or Dad for any money-not this week!

Later that afternoon, Sam noticed a second-hand book sale going on. He went there and had a quick look. Two books caught his eyes. The first was a cookbook of Puerto Rican foods, and the second was a book about women explorers(探险家). "Rosa would like these," Sam thought, "But would it be tacky(蹩脚的) to give her second-hand books for her birthday?"

Sam decided that a second-hand gift was better than no gift at all. Besides, Rosa supported recycling in a big way. So, she would probably like it. With his last dollar, Sam bought the books and went home. He felt a little better.

The party was on Saturday. Rosa opened all her gifts and thanked everyone for the nice things they had given her. She paused(停顿) when she opened Sam's gift, which made him wonder if she liked the books, but nothing was said.

When Sam got home, he opened his e-mail and found this note from Rosa.

Dear Sam

Of all the gifts I received today, yours was the nicest. How did you know I would love a book about women explorers and a cookbook of Puerto Rican foods? Now I have something to read that will inspire me to follow my dream of becoming an adventurer and I have a book that I can share with my grandmother.she is getting older and wants to be sure her granddaughter knows how to make the wonderful foods of Puerto Rico. Thank you so much.

Love,

Rosa.

The week turned out to be a good one after all.

Pan Yuzhen, 77, comes from Taijiang County, Guizhou Province. She is an inheritor(继承人) of Miao embroidery(刺绣).

" The girls in my hometown can embroider at an early age. When I was five years old, I learned embroidery from my mother and sister. Miao embroidery skills are not easy to learn, but I have learned all embroidery methods," Pan said. At first, Pan embroidered for her own use, but as she grew older and married, her skills were put to use for her family, creating beautiful embroidered clothes.

Pan's daughter Zhang Yammei, who was born in 1977, suffered from an illness at the age of three. To treat her daughter and feed the family, Pan embarked on (开始) a journey, travelling to different cities to sell her Miao embroidery products.

In 1999, Zhang went to Beijing to join her mother. At that time, Pan had a store in a market. Here, she met a lot of foreign friends who were attracted by her embroidery skills and encouraged her to expand her business abroad." They advised me to go to foreign countries and sell cultural and creative products. Then I went to the US to do business connected with Miao embroidery," Pan said.

In 2016, Pan's career took a huge leap forward as she worked with a famous clothing brand in China . With the help of the brand, Pan went to the UK to take part in different fashion shows. Now Pan is well- known. Pan hopes more young people can inherit Miao embroidery skills.
