| A．Means of ewaste recycling B．How ewaste comes into being C．The benefit of ewaste recycling D．The technologies of ewaste recycling E．The importance of the electronic waste recycle F．Modern technology brings convenience and ewaste |
Modern technology does bring us many conveniences（便利），from WiFi（无线网络）enabled cell phones and ever smaller laptop computers that make entire lives easy to energy efficient washers that use half the power and time to complete their tasks. However，these new toys and equipment finally become electronic waste （ 电子垃圾）（e waste）once they are out of use.
E waste includes everything from empty printer ink containers to broken refrigerators. As people buy new items to replace aging electronics or make upgrades（升级），more electronic waste comes into being. In some cases，such as 2009's switch from analog（模拟）to digital television broadcasting in the United States，changes in technology are so great that old equipment may not even work at all with new systems.
There are many reasons why it is important to recycle electronic waste. Much of the material used to construct electronics，including metal and plastic parts，can be recycled into new items at a discount of the cost and energy use needed to create things from new raw materials（原材料）. Additionally，many electronics contain poisonous substances （有毒物质）that are harmful to the environment and could be deadly if they go into an area's groundwater. When properly recycled，they can be reused and will not do harm to the environment. Because of these environmental concerns，many areas require by law that electronic waste be properly recycled.
The availability（可用性）of ewaste recycling programs varies from place to place. In some areas，annual collections are held once or twice a year as a means of dealing with ewaste as well as used engine oil or other waste that is harmful to the environment. There are also some good alternatives （替代品） to recycling your ewaste. Any items that are in working condition can be given to friends or donated to charities（慈善机构）like Goodwill or the Salvation Army，who rely heavily on donations （ 捐赠） . Freecycling ，or passing on your unwanted items to those in need of them，is also a means of finding new homes for used items.
Ewaste recycling helps protect the environment by reducing the amount of poisonous materials placed in landfills（垃圾场）and saving recyclable parts to save energy and other resources. Recycling is a way of life. Stick to that choice every single day and recycling will become second nature to us.

Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Knowing how to go through your math test and check your work can save you from handing in a test full of mistakes that can be avoided.
Write it out
You can also check a math problem by writing everything out on paper. Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.
Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether or not your answer is the correct one.
Plugging in
You may find that a variable(变量) isn’t good enough or have a problem where you have to solve for a variable. This is the only real way to assure yourself that the answer you’ve found is correct.
Check for a reasonable answer
For example, if you get an answer in the millions and you know it should be in the thousands, you’ve likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you’ve got on the first try.
| A．Do the opposite |
| B．Correct the answers |
| C．Plug the variable in the equation (方程) to check it out. |
| D．Therefore you’ll improve your grades, as well as your math skills. |
E. It also helps you to figure out everything after you have already finished the test.
F. If the result of a problem seems to make no sense, it indicates that the answer is incorrect.
G. This helps you to know what information you have and what information you need to solve.
