Task 1

Directions: After reading the following passage, you will find 5 questions or unfinished statements, numbered 36 through 40. For each question or statement there are 4 choices marked A, B, C, and D. You should make the correct choice.

In many countries, such as France, Greece, and Japan, it is often more difficult for students to pass the college entrance exams than to do the course work when they are actually in college, and students who don't have much money are at a disadvantage. Students prepare for these tests for years in advance. Often，stu-dents attend a private school at night to get ready for them. These private schools are usually expensive. If their families don't have much money, students can't attend, and they might not pass the entrance exams without this extra preparation.

In contrast, students can easily get into an American or Canadian college at least more easily than in other countries. American students take an entrance exam called the S.A.T. (the Scholastic Aptitude Test (学习能力测试)). However, colleges do not consider only S. A. T. Scores. They also consider a student's grades and activities throughout high school. A student who has done well in high school will probably get into college.

What happens when a student finally enters a college or university？ Students in China, Korea, or Japan might find their college studies easier than high school work. On the other hand, when American or Canadian students begin college, many of them discover that they need to work very hard and study seriously for the first time in their lives especially if they plan to go to graduate school.

In France and Greece, students find that ______.

A．they have to do extra preparation to pass the entrance exams

B．private schools are inexpensive

C．course work in college is more difficult

D．college entrance exams are more difficult
