23、Recently I have carried out a survey among 578 students from a boarding school about how they go home at the weekend．

As is shown in the pie chart, 45% of the students' parents drive their cars to pick up their children, because it is the quickest way to get home．Besides, 30% of the students take the school bus home, saying that they don't want to occupy their parents' valuable time．In addition, 15% stay at school over the weekend in order to save more time for their studies．However, considering the advantages of avoiding traffic jams and keeping healthy, 10% choose to go home by bike．

In my opinion, riding a bike home is my choice as it is low - carbon as well as energy -saving．
