Most students like junk food（垃圾食品） because it is tasty． Whether it should be allowed in schools or not is still a question． Just as every coin has two sides， junk food in schools has its advantages and disadvantages．
Most junk food is quite cheap， tasty and easy to get． If a child forgets to carry a lunch bag， he or she will go hungry for most of the day． Here， junk food helps him or her to have something to eat． Moreover， it is possible for students to save a lot of
Sometimes having junk food instead of part of one's main diet is considered to be OK． It doesn't have a big influence on a person's health if someone only eats from time to time．
Compared with some junk food with high oil and salt， food like potato chips or juices can be made in school dining halls． So students don't have to choose unhealthy food from outside．
However， too much oil， salt and sugar in junk food are harmful to human bodies． Some of them cannot be broken down in the body． If someone eats too much junk food， it can lead to obesity（肥胖） and other health problems like heart trouble， high blood pressure and so on．
Usually， children have snacks between classes． There is a sudden increase of sugar， so they get a lot of energy and become too active． But when classes begin， the effects（作用） of the snacks begin to reduce， they become slow． This causes low energy levels and lack of concentration（注意力）． It has a bad influence on a student's performance during classes．
In all， it is important that parents and schools should provide their kids with healthy and balanced food and make them know the disadvantages of junk food．Then they will make healthier choices for themselves．

Recent years have witnessed the returning of bikes across China． An increasing number of people choose cycling instead of driving to school， to workplaces or to do sightseeing． Bike﹣sharing plans are warmly welcomed in many． cities． Mobike had 5.85million active users while Ofo had 1.4million in the first week of this year．
People can unlock the shared bikes by simply using their smartphones． All bikes have GPS and can be left anywhere in public for the next user． They're popular among many Chinese people
because they help solve "last﹣mile" problems in cities． For example， many people find it difficult to get to the hotel when they get off trains or to travel around the city．
However， the plans have also led to problems such as illegal（非法的） parking， vandalism （故意破坏） and theft． In February， two nurses in Beijing were placed under administrative detention（行政拘留） for five days for putting locks on two shared bikes．
In fact， these problems are also shared by bike﹣sharing plans abroad． Started in 2007， V6lib is the largest public bike sharing system in Paris． At its early period， it also met with problems of vandalism or theft． To deal with these problems， the company came up with the idea of encouraging people to return the bikes to stations by rewarding free time for their next rides．
Now， Chinese service Organizations are also trying to deal with these problems． For example， Mobike sets a 100﹣point credit score（信用分数） for each user， but the points will be taken because of his or her bad behavior． Once a score drops below 80， bike rental（租金） will be increased from 1yuan to 100yuan per 30minutes．
