22.In the United States, the traditional school year is September to June. Summer school used to be seen mainly as a place for high school students to repeat classes they failed. But summer programs have expanded. Students often go to summer school so they can ease their class load during the school year. Or, it might give them more freedom to choose the classes they want during the regular term.Summer school students do the same amount of work as if they took the class during the school year. But they do it in a much shorter time—just one to two months. They generally attend school for three to four hours every morning, five days a week. Another choice for many students is to take classes online. Students work by computer at home or wherever they have an Internet connection. They could even be traveling with their families. However, some online classes require students to come to a classroom to take tests. Students may also have to take part in group discussions with the teacher online. And there may be a required number of hours to spend logged on each day. Yet there may also be freedom to do the work anytime, day or night.(10分)22.1 A student in the United States doesn’t need to attend school in ______.(2分)A. MarchB. AugustC. DecemberD. February
