We all need physical exercise．Exercise uses up food we eat and keeps the body full of energy．It works our muscles and makes our heart work hard so as to send blood to our muscles．So，exercise makes our heart and muscles strong．Exercise also makes us feel refreshed．If you exercise a couple of times a week，you will stay happy and healthy．
Some Western countries，such as the United States，have problems with exercise．In the US，many people don't have enough exercise because it is hard for them．People have to work from dawn till dusk，so they don't have time to take exercise．They work in office buildings sitting in chairs all day long in front of computers．They cannot get much exercise sitting at desk passively．
Some Westerners can get exercise walking from their homes to work．However，the majority of the people cannot do this．It is too far from their homes to their offices．They have no choice but to drive to work．In fact，some have to drive one or two hours to their offices．This has anunfavourable effect on them in two ways．First，these people don't have a chance to exercise because they are sitting in their cars for two to four hours each day．Second，driving is challenging especially in rush hours and calls for too much attention．It makes a person worn out．So，when these people arrive home at night，they don't have the desire to take exercise after work．
Today，many people in the West are overweight，which causes health problems for them．Doctors say exercise can help people both lose weight and improve their health．So many people are trying to get more exercise．But it takes time to change，and when people don't see a difference right away，they will lose heart and stop exercising．

1．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．

2．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 -
