Within half a year, you will enter senior high school. Then, in Senior 2 or even Senior 1, you will have to 1. a choice—become a humanities student (文科生) or a science student (理科生). In the national college entrance examination, humanities students will take exams in history, geography and politics, while science students take physics, chemistry and biology tests. However, some may find the division (划分) is too limiting (限制的): Why must we choose 2. humanities or science?

China is actually changing its national college entrance exams now. Over 12 provincial-level regions have already said they would not have the science-humanities division in the next few years. Students are still required to choose three subjects from the six. But they can choose 3. three. That means they can freely choose the subjects they are good at or interested in.

However, not everyone likes this change. Some worry students have problems making the right decisions because there are too many choices. Others worry this change will cause students to learn more subjects if they are not sure about what subjects to choose. 4., the division seems easier, but it is not good for students’ future development. Many students are too young to have the clear ideas about their future jobs 5. the subjects they choose to learn now may be useless in the future.

And some schools in Shanghai have already 6. out a lot about how to help students face the new change. Teachers can help students get to know their advantages and disadvantages. Then students can choose the courses they want and take the classes in different classrooms. Students can also experience different jobs in real life to know what knowledge is needed. We can find that 7. not only happen in exams, but also in courses and schools.

In a word, no matter what will happen in the future, for now, you have to get used to the new situation as 8. as possible.

According to a recent survey, over 23 percent of Chinese high school students have trouble.
