The days when a cellphone was used for nothing beyond calling and texting are gone. Today, we turn smart phones into magical machines with apps that transform them into musical instruments or business machines or video players. But it turns out that we are only searching the surface. Who knew that smart phones would make pretty good satellites?{#blank#}1{#/blank#}

Smart phones save the rainforests

       Detecting illegal logging(盗伐) may sound like a novel app, {#blank#}3{#/blank#}: in Indonesia, the non-profit organization Rainforest Connection' wants to use donated Android phones to detect illegal logging. As Newscientist reports, “The phonesare equipped with solar panels specifically designed to take advantage of the brief periods when light reaches the forest floor. Their microphones stay on at all time, and the software listens for the sound of a chainsaw(链锯).”

        Researchers at the university of Illinois have developed an iPhones app that turns the phone into a fully featured mobile medical lab that uses the phone's camera to detect proteins, bacteria, viruses and other organisms.

    Did you make financial decisions last New Year's Eve? Did they fall by the wayside? If so, you are not alone.{#blank#}1{#/blank#}.

    Make a smart budget

    Did you plan to make a budget and fail to do so? This is a perfect time to start, as you are heading into the new year. You may be able to stop yourself from overspending if you realize how overextended you are. If you've taken no other financial steps this year, start by setting a realistic budget.{#blank#}2{#/blank#}.

    Control your spending

    Even if you had a budget, were you able to stick to it?{#blank#}3{#/blank#}. Use it as a psychological advantage－you have less to spend so you need to shop harder for bargains and research prices. Impulse buying (即兴购买) will be less likely to attract you and your spending should be more focused as a result.

    {#blank#}4{#/blank#}.

    You had a savings goal, didn't you? If you didn't have a specific goal, it may be why your savings effort failed. Set a smaller savings goal now, and use that to build a larger savings goal for the upcoming year. Make sure that you equate（使等同）your savings with a specific goal.

    Reduce your debt

    Debt reduction is an important goal, especially in the case of high-interest debt such as credit cards. It's easy to get into an unrecoverable increase of debt if you have no plan to keep debt in check. It is a longer-term goal, but one you need to start right away.{#blank#}5{#/blank#}. That may be a tall task, which is all the more reason to start immediately.

A. Increase your savings

B. Have a clear goal for your debt

C. You will go on with your new decisions

D. Most other financial improvements will follow

E. Start small by setting a spending budget for your shopping

F. But this year, you can make some progress on your financial goals

G. Attack the debt with the highest interest rate, and control your spending

    Most of today's Chinese Americans are the descendants (后代) of some of the early miners and railroad workers. From the start, the Chinese had lived apart in their own separate neighborhoods. {#blank#}1{#/blank#} In each of them the residents organized an unofficial government to make rules for the community and to settle disputes.

    Chinese Americans keep many aspects of their ancient culture, even after having lived here for several generations. For example, {#blank#}2{#/blank#} Members of the family lend each other moral support and also practical help when necessary. From a very young age, the old values and attitudes, including respect for their elders and a feeling of responsibility to the family, are passed from the older generation to the young. {#blank#}3{#/blank#}

    The high regard for education, which is deeply rooted in Chinese culture, and the willingness to work very hard to gain advancement, are other noteworthy characteristics of theirs. {#blank#}4{#/blank#}

    Chinese Americans make up only a tiny part of American population; there are fewer than a million, living chiefly in California, New York, and Hawaii. As American attitudes toward minorities and ethnic differences have changed in recent years, {#blank#}5{#/blank#}

    Parents of children and teens who play football may worry about their bodies getting injury. Younger football players have the lowest chance of injury. {#blank#}1{#/blank#} Therefore, it's necessary for players to know the rules of playing football whether they are young or old. The following can be used to reduce the chance of injuries while players are still enjoying the game.

    {#blank#}2{#/blank#} The American Academy of Pediatrics advises players and their families talk about whether the risks of injury outweighs the benefits of playing football. Football has many benefits, including regular exercise, learning to be part of a team, and social growth and development. Families who decide to play can take steps to reduce the chances of serious injury.

    Play by the rules. When players know the rules of the game—what's legal and what's not—fewer injuries happen. {#blank#}3{#/blank#} For example, players should know that in football they can't come from behind, crash into a player's legs, and steal the ball. It's legal and safer to go after the ball rather than the player.

    Wear legal equipment. {#blank#}4{#/blank#} Because illegal equipment leads to serious injuries of the head and neck. It's also the leading cause of severe injuries in football, but remember the protection of legal equipment doesn't depend on its quantity.

    Get good training. Players should learn the right way to use a tackle (装备). {#blank#}5{#/blank#} Correct training could lower injury for younger players. Older players could be at a greater risk of injury if they first learn to use tackle and never learn the correct skill.

A. Take steps to lower football injury.

B. Weigh the risks and benefits.

C. The more legal equipment players wear, the less injury they will get.

D. Legal equipment can give football players important protection.

E. Players should know what to expect from each other.

F. Doing this and practicing the skills often make sure players are correctly trained.

G. As players get older, stronger and faster, the chance of injury goes up.
