【简答题】
Several days ago , some students from the US visited our school.When we talked , I discovered 1 differences in school life between the US and China.For example , each class_ 2 fifty minutes in the US.It is a little 3 _than that in China.We usually have forty or fortyfive minutes in each class.Another difference is that they have less break time between 4 . Besides , although most schools in both countries finish their 5 classes at 12 o’clock , the students in the US only have an hourlong break , so they 6 eat lunch quickly.Their afternoon classes begin at 1 : 00 p . m. and school is over 7 3 : 00 p . m.Then they take part in club activities or play sports. Many Chinese students don’t work during their high school years , while the US students like to find a parttime job in 8 free time.They don’t have a dream job in mind.They think 9 is no difference between jobs.Working is a useful experience for them and they can make money at the same time.Some of them even take oneyearfulltime jobs 10 they leave high school and then go to college.
