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．
B．Keep sending your location．
C．However，these services are not for all children．
D．With its help，you can easily share your location with them．
E．Check-ins ease worries so they don't have to follow your every move．
F．Others show where you are all the time or for a period of time you set．
G．Some location services operate like Facebook，where you invite and accept friends．發(fā)布：2025/1/1 18:0:1組卷：7引用：4難度：0.7 -
