Electricity bills can be highly expensive and the power we consume comes at an even greater cost to the environment when you consider that over 85% of the electricity produced in the United States comes from fuels. Whether you’re concerned about cleaning up the environment or you simply want to reduce your electricity bill，residential wind power generators（发电机）could be a solution.

Producing wind power at home will not work for everyone. If you live in a over-populated residential area，there may be certain laws and zoning requirements that prohibit the use of windmills（风车）.If you live on 1 acre of land or more,you probably won’t have any issues but you should investigate carefully to make sure that wind power generators are both legal and practical where you live. Even if there are no laws or regulations prohibiting wind power generators you still need to be in a location that gets enough wind on a regular basis.

Some producers of wind generators recommend that you live in an area with wind speeds that average at least 10 mph. Newer models have been developed recently that can operate with wind speeds as low as 4 mph but maximum efficiency is achieved at higher wind speeds. Before you fix a wind powered system,you will have to determine your power requirements. Will you be using it to charge a small battery for a boat or vehicle or will you need enough power to run your entire household and be completely off the grid（电网）？Once you know what your power requirements are，you can start shopping around for a system that can meet those needs.

Wind power generators are a great solution for a lot of people.They’re an ideal solution for remote locations where it would be impractical or simply too expensive to tap into the grid.They are quiet and totally clean，producing no pollution. They require no fuel and very little maintenance. Residential wind power offers a lot of benefits but it’s not for everyone. You’ll have to have some money up front to pay for the system and equipment;however,you could save quite a bit of money if you’re able to do much of the work yourself. You’ll also need to live in an area that gets enough wind to make the equipment worthwhile. You’ll need to do your homework before you make a purchase,but wind power generators could be a great solution for producing clean, low-cost energy.

Visit any junior high or high school and you will experience the power of influence. Clothing, hairstyles, attitudes and even the language are all gained by some amount of influence, whether it is from commercials, fashion, trends, celebrities or music. Teens and preteen children are influenced by these various factors. However, a child’s friends are the No. 1 influence.

Before you think your children’s friends could never lead one another astray (误入歧途的), think again. A child may experience an event that has caused overwhelming stress or may have problems at home or school, which causes negative behavior. Negative influences of a child’s friends can come without warning.

“Parents who ask their children where they are going, who they are going with and request a meeting with their children’s friends and the friends’ parents have already taken the first step,” says Mara Berkley, family therapist and professor at Bristol University in Rhode Island.

Lynn Rexroat of Chillicothe, Illinois, uses this method to keep tabs on her children. “My oldest son knows that in order for him to go anywhere with a friend, especially one I haven’t met before, I have to speak with that friend’s parent to make sure the arrangements are agreeable with us both,” she says. “I don’t interrogate (质问) them by asking about their private life. I just want to know that the parents of the other child know what the boys are planning to do. I feel that by my wanting to know I am protecting my son.”

When a parent suspects that their child is hanging out with “the wrong crowd”, the last thing on their mind should be discipline. Instead, Berkley says a parent should be more interested in finding out the reasons behind the behaviors and the child’s choice to keep company with these types of friends.

1.We can infer from the second paragraph that 　　　　 .

A. two children usually go astray together

B. a child can be negatively influenced only when he meets problems　　

C. a child can easily go astray under the influence of a friend

D. parents know exactly when a child is negatively influenced

2.Mara Berkley probably agrees that you 　　　　 when your child is going out with his friends.

A. should track him secretly     B. should not ask him

C. can stop him going out    D. do something to interfere

3.How does Lynn Rexroat protect her son according to the text?

A. She questions his son directly.　　

B. She meets his son’s friends herself.

C. She makes arrangements with the parents of his son’s friends.

D. She communicates with the parents of his son’s friends.

4.The underlined part “keep tabs on” in the fourth paragraph probably means “ 　　　　 ”.

A. watch over    B. win over    C. bring back     D. take control of
