Carbon dioxide is released when oil，coal，and other fossil fuels are burned for energy-the energy we use to power our homes，cars，and smartphones.By using less of it，we can limit our own contribution to climate change while also saving money.（1）GG.
Buy energy-efficient appliances
Since they were first set in 1987，efficiency standards for dozens of appliances and products have kept 2.3 billion tons of carbon dioxide out of the air.That's about the same amount as the yearly carbon pollution coughed up by nearly 440 million cars.When shopping for refrigerators，washing machines，and other appliances，look for the Energy Star label.（2）DD.
Reduce water waste
Saving water reduces carbon pollution，too.That's because it takes a lot of energy to pump，heat，and treat your water.（3）AA.Turn off the tap while brushing your teeth.And switch to water-efficient equipment.If one out of every 100 American homes did this，about 100 million kilowatt-hours of electricity per year would be saved，avoiding 80，000 tons of global warming pollution.
（4）BB
Gas-smart cars，such as hybrids and fully electric cars，save fuel and money.And once all cars and light trucks meet 2025's clean car standards（標(biāo)準(zhǔn)），which means averaging 54.5 miles per gallon（加侖），they'll be a mainstay.For good reason：Compared with the 2011 standards，Americans will spend ＄80 billion less at the gas station each year and cut their emissions（排放）by half.Before you buy a new set of wheels，compare fuel-economy performance.
Rethink planes，trains，and cars
Choosing to live in walkable smart-growth cities and towns with quality public transportation leads to less driving，less money spent on fuel，and less pollution in the air.
（5）FF.Air transport is a major source of climate pollution.If you can take a train instead，do that.
A.So take shorter showers
B.Drive a fuel-efficient car
C.Cut down on your water consumption
D.It will tell you which are the most efficient
E.Change only happens when individuals take action
F.Less frequent flying can make a big difference，too
G.Here are some effective ways each one of us can make a difference

1．Walk Out of the Comfort Zone and Try New Things For most high school students，free periods （課、節(jié)） are useless.From what I have seen，few do homework. （1）
.This makes it impossible for those who actually want to do work to complete any.As a senior next year，I think extra periods should be used to take optional subjects.
（2）.Now is the time for us students to choose a suitable one.We will experiment in different fields of study.We will never know if we are interested or talented in a subject if we don't try it.
In my 8th grade，I was told that I had to take an art class as a graduation requirement；so in the 9th grade I took Studio and Art.One of the projects was to build a clay pot，but I built mine incorrectly，so it broke in the kiln （窯）. （3）.Now I know for sure that I do not want to be an artist.However，the class was one of my favorites that year.I was able to try new activities and test my ability.
（4）!College is when we should focus on a specific major，but high school is when we have to figure it out.
Half of all college students change their major at some point.By doing that hundreds of dollars are wasted on classes that they would have never needed to take.So use our extra periods to find out what we want to do in college. （5）.
A.Our school offers many classes
B.We should find out what we are good at
C.I've avoided anything related to art since then
D.Instead，many are on their phones and talking
E.I found out that I have no artistic ability at all
F.Walk out of our comfort zone and try new things
G.The classes we choose can influence us in the future發(fā)布：2025/1/1 18:0:1組卷：7引用：5難度：0.5 -
2．Most smart phones allow you to run location-sharing software that uses the phone's GPS capability to let friends and family know your exact location．There are lots of great uses for this technology．（1）
So make sure you're permitted to use an app or service，and pay attention to how you are using it．Here're some important points you may find helpful．
Choose what's best for you．Some location-sharing services are games that let you give a shout-out when you've turned up at a particular spot．（2）Still others continue to share your location until you change the setting．Be sure you know exactly how your service shares your location．
Know who your friends are．（3）This means people can search to see if you're online and add you as a friend．It's important to remember that sharing your location with people you've never met in real life is risky，so you should carefully manage friend requests and share your location only with people you know and trust．
（4）Some services automatically stop sending your location after a period of time，but others will send it forever-until you stop it．Review your contact list periodically and delete anyone to whom you no longer feel comfortable revealing your location．
Update parents．Location-based services are a great way for teens to let parents know where they are without having to call or text．（5）If you're heading home late at night，you can also use a service like Glympse to share your location as you drive，so they'll know if you have car trouble or get stuck in traffic．A．Check back often．
