When children start kindergarten, evident gaps in science knowledge already exist between Whites and minorities and between youngsters from upper-income and low-income families. And they often deepen into significant achievement gaps by the end of eighth grade if they are not dealt with during elementary school.

    The findings suggest that, in order for the United States to maintain(维持) long-term scientific and economic competitiveness in the world, policymakers need to renew efforts to ensure access(n.使用或见到的机会，权利) to high-quality, early learning experiences in childcare settings, preschools and elementary schools.

    The researchers' study tracked 7,757 children from their start in kindergarten to the end of eighth grade. Researchers found that, among kindergarteners with low levels of general knowledge, 62 percent were struggling in science by the time they reached third grade and 54 percent were struggling in that subject in eighth grade. And general knowledge gaps between minorities and Whites were already large at the time when students began kindergarten.

    “Children growing up in low-income families typically experience comparatively fewer early opportunities to learn about the natural and social sciences,” the authors wrote. “Their parents often have lower educational levels and therefore less science knowledge themselves as well as fewer resources available to direct the children's academic growth. Children raised in poverty often attend poorly resourced schools that futher limit their academic opportunities.”

    Morgan said that, within families, parents who regularly talk and interact with toddlers(学步的儿童) can point out and explain physical, natural and social events occurring around them daily. This might help youngsters learn facts and concepts that will prepare them to take better advantage of science instruction they receive during elementary and middle school.

    Writing an article for your school newspaper can be exciting and rewarding, especially when you proudly see your name in print.

    Decide on a topic. {#blank#}1{#/blank#} If you plan to write a news article for a monthly newspaper, you will need to take into consideration whether the topic will be relevant before printing. To get ideas for stories, listen to your fellow students and find out what has them talking. Follow developments within your school and community to get information on what would interest your readers.

    Do your research. There is an old saying in law that a good lawyer never asks a question that they don't know the answer to. {#blank#}2{#/blank#} To sum up, the more, the better.

    Attract the readers with a lead. As the beginning of a newspaper story, a lead has to be direct, but it does not mean you don't need to entertain the reader as well. {#blank#}3{#/blank#} Your lead must be short, but it must also state as many of the essential parts of you story as possible.

    Consider the 5 Ws and H. These are the meat and potatoes of your news articles. You article must answer all of these questions: Who, What, When, Where, Why and How. Once you have answered these things, you can feel confident. {#blank#}4{#/blank#}

    Write, edit, rewrite and repeat as necessary. So, much about having a successful final product is about being willing to spend time and effort in editing and reviewing process. {#blank#}5{#/blank#} After that, make changes as a result. Having taken some useful suggestions, you are to make your article readable not only for their content, but also for their quality.

A. Think about what is happening on campus.

B. You have effectively informed your readers.

C. Get them interested with an interesting beginning.

D. Do not be afraid to accept positive comments.

E. News articles are suitable for the date of publication.

F. Take note of anything particularly unusual.

    For those who may not be familiar, there is no such thing as a bicycle grants(补助金). As a matter of fact, there are a number of organizations and programs offering bicycle grants to bicyclers all over the world. Now of course, you can't simply receive money, because you want to buy a new mountain bike. Usually, those awarded grants are working on improving the quality of life. People are excited about the bicycle grants. This type of influence and achievement is gaining the attention of various companies that want to help by providing the necessary funding.

Eastman Kodak Company

    Kodak has developed a fund called the “Kodak American Greenways Awards". They are cooperating with the National geographic Society and the Conservation fund. Each year, they present grants as high as $2,500. The “seed” grant award is awarded to organizations that focus on improving blue ways, greenways, natural areas, and trails.

    US Government

    The government has developed their only program for bicycle riders, called" The US Department of transportation's Recreational Trails Program". The government's program is primarily focused on funding trail projects. The benefits of the fund is recreation, which includes bicycling, hiking, in-line skating, snowmobiling, all-terrain(地面)vehicle riding, and so forth. The great addition to the fund is that they distribute the funding to all the states. This means that everybody has the opportunity of receiving bicycle grants.

    Bikes Belong Coalition

    The Bikes Belong Coalition makes putting more people on bicycles their priority. They advocate for a better environment, recreation, sports, and better health, by way of bicycling. At the same time, they provide funding for supporting projects and bicycle facilities. Some of the projects they accept are paved lanes and bike paths. Applications for their grants can be submitted by either a facility class or a supporting class. Also, Bikes Belong Coalition are not quick to award bicycle grants to those who have been awarded in the past 3 years. This is partially due to their limited amount of funding

    It began as a game: High school and college students studying computer technology figured out they could use personal computers to break into telephone company computers and make free, long-distance telephone calls. These young computer talents soon gained the name "hackers".

    Police arrested a few hackers, but many went on to even more complex hacking. One of them was arrested for making illegal telephone calls and later he used a phone to change a police officer's credit records to get back at the officer for arresting him. He also used a computer to change his college records to give himself better grades.

    As hackers gained experience, they began invading computers at banks, airlines and other businesses. In one case a hacker instructed an airline's computer to give him free airplane tickets.

    The U.S. government is worried that hackers may break into its networks of defense computers. The government's secrets are easily attacked because thousands of government computers are connected by telephone lines that hackers can get into.

    In November 1988, a college student entered a U.S. Defense Department computer network called Arpanet. The hacker injected a computer program that made copies of itself throughout Arpanet. Some hackers use viruses to destroy all the data in a computer. But in this case, government officials shut down the network before the program reached every computer in the system. Shutting down the system angered many researchers who were using the computers. The hacker turned himself in to the police and he was charged with a crime.

    The incident put the spotlight on computer hacking in the United States. Many companies have hired experts to protect their computers from hackers, and many computer experts now advise companies on how to protect their computers.

    The U.S. government believes foreign governments have hired hackers to try to break into top-secret defense computers.

    Experts disagree over whether a computer network can ever be safe from hacking. But in the future, some of the most outstanding minds in the U.S. will be working to frustrate the attempts of computer hackers.

    The impression you make at the beginning of an interview is very important. Employers often decide to hire someone in the first three minutes of the interview. They judge you by your appearance, attitude and manners.

    A friendly smile when you walk into the room is important. A smile shows a confident and positive attitude. When you introduce yourself, make eye contact with the interviewer. Some interviewers offer a handshake. Others don't.

    Try to be as natural as possible. But pay attention to your body language. The way you sit, walk, gesture, use your voice and show feelings on your face is all part of your body language. It makes the interviewer know how you feel about yourself and the situation you are in. Are you feeling positively about yourself？Your abilities? Your interest in the job？

    Speak clearly and loudly enough. Show interest and enthusiasm in your voice. When you speak, look at the interviewer. Also, don't say negative things about yourself, or former employer.

    Listen to questions carefully. If you don't understand a question, ask the interviewer to repeat or explain:

    "I'm sorry, but I didn't catch that."

    "Almost everyone is nervous in a job interview. Interviewers know that. They don't expect you to be totally calm and relaxed. But they expect you to try to control your nervousness. They expect you to show confidence in your ability to do the job.

    At the end of the interview, thank the interviewer for her or his time. It's a good idea to send a short thank-you letter right after the interview, or deliver it by hand.

    Phone the company if you have not heard anything after one week. Ask if they have made a decision about the job.

Good luck!
