The students in America usually begin high school at the age of 13 or 14. Some leave at the age of 16. But most finish the 4-year high school study. They do not get their first full-time work or begin college studies until they are 17 or 18 years old.

  The high school day is about 7 hours long. Part of the day is made into classes of about 50 minutes long. The students have lunch in the middle of the day. American students study English, history, math, science, art and languages. Some also learn job skills. They can learn how to use a computer or how to mend a car. Other students may learn by working in an office, a hospital or other places one day a week.

   Jean Wilton Anderson is 16 years old. She lives with her parents and two younger brothers in Bethesda, Maryland, near Washington D.C. Jean studies at Walt Whitman High School. There are about 1,500 students at the school. Most of them will go up to colleges.

   Jean wakes up early every morning. She begins school at about 7:30. This is her third year of high school. Every day she takes classes to learn English, world history, physics and trigonometry(三角学). She also has a class about different religions(宗教).And she plays the violin in music class. School ends at about 2 o’clock in the afternoon. Yet, Jean stays 2 or more hours longer every day for sports. Jean arrives home at about 5 o’clock in the afternoon. She eats dinner. Then she starts her homework. Students in America have their way of talking. They use the word “like” all the time. Jean and her girlfriends wear blue jeans and shirts or sweaters every day. The boys at her school also wear blue jeans. But they like to wear blue jeans that are several sizes too large for them.

   Like students of her age in most parts of the country, Jean begins to drive a car. She does not have her car. She must use the family’s car. Most of the students in high school have their own cars. Many of them drive their cars to school every day.

1. Which of the following is not true to the high school?

My school makes students take one religion (宗教) class every year. But religion is really hard, especially with Mr Frank Smith for a teacher.

Mr Smith is 55 years old, with grey hair and a moustache (胡子). He always wears a blue school T-shirt, shorts and tennis shoes with long white socks. My friends say he looks like a cat.

In his class, we did yoga (瑜珈) and meditation (冥想) (actually most of the children in my class lay on the ground sleeping), tasted some strange tea, had classes outside in the garden, and watched videos and movies about Tibetan Buddhism (藏传佛教), God, and so on.

It was fun sometimes. However, the course (课程) was quite hard when it came to tests. The girls often worked until one or two o'clock in the morning on nights before the tests, but they still got bad scores.

When our test scores were bad, he would give us some makeup assignments (补考作业). Once I got a B, which I thought was bad, so I asked Mr Smith for an assignment to bring up my grades.

As a matter of fact, his assignments were often worse than the tests. The tests were just a lot of multiple-choice, fill-in-the-blanks, or short essays (文章). But his assignments usually included a speech in class.

I was not afraid of public speaking, yet it took me three days to collect the information, two days to write the speech, one day to make a PowerPoint and several hours to prepare. I knew my presentation (课堂展示) was good, because I saw Mr Smith's big smile when he listened to me. He gave me an A at last.

After finishing the course, I may not remember how hard it was or the meaning of some vocabulary. But through Mr Smith, I learned a lesson that will be with me my whole life. That is: no matter what we do, we need to put our hearts into it, and then our work will pay off.

The religion class is hard because Mr Smith _______.

A. uses strange ways to teach in his class.

B. never gives good scores, however hard you try.

C. gives difficult tests and make-up assignments.

D. likes students to make good presentations.

How could students get good scores in Mr. Smith’s class?

A. Work hard by studying late into the night.                  

B. Remember all of the vocabulary.

C. Pay attention and take notes in class.                              

D. Do well on the make-up assignment.

From the course, the writer learned that ____.

A. people should always be given a second chance

B. people should always put their hearts into their work

C. it is good to do yoga and meditation             

D. it is good to choose strict teacher

D
College libraries are designed primarily for research and study. To explain its use, let us choose a research topic and follow the step-by-step procedure of looking up the material for the paper. Suppose your assignment is to write a paper on a novel called “The Sun Also Rises” by American writer Hemingway. The first step is to go to the main catalog. Many small drawers on the large wooden cabinets are lined up in alphabetical(字母的) order. Each of the drawers contains hundreds of alphabetical ordered cards. These cards are printed references to all material available in the library. Title cards are cataloged() by the first word of the book title, leaving out the articles like “a”, “an” and “the”. And then you get the cards for the books you need. On the upper left corner of each card is the call number. This is the numerical code that shows where the book is located in the library. The library has open and closed stacks. If your book is on the open stacks, you can go to the open-stack room, and according to the call number find it out by yourself. There are only about 30,000 books on o pen stacks, while most of the 800,000 books in our library are kept in closed stacks, which are accessible only to teachers and graduate students. For undergraduates like you, borrowing books from the closed stacks have to be done with the help of our librarian. In that case, you must fill out a call slip(纸条) for the book, showing the call number, author and title. You can get call slips on tables near the catalog cabinets. You show your call slip together with your library card to a librarian at the information desk. He or she will help you find the book out in the closed stacks.
53.What is the main purpose of this text?
A. To present readers a brief introduction to a college library.  
B. To guide readers how to find books needed in a college library.
C. To tell readers how to fill out a call slip in a college library.
D. To show readers where to find books in a college library.
54.What letter you should look for on the title card for the book “The Old Man and the Sea” by the Hemingway?
A. The letter “t”.           B. The letter “h”.           C. The letter “s”.           D. The letter “o”.
55.How are books arranged and shelved in the library?
A. By call numbers.                                          B. By call slips of authors’ names.
C. In alphabetical order.                             D. By the first word of book title.
56.Suppose you are an undergraduate and you want to borrow a book from the closed stacks, which is the correct order to do it?
a. go to the main catalog                     b. show your call slip and library card
c. find out the call number           d. fill out a call slip
e. get the cards for the books
A.a-b-e-d-c                   B. a-e-c-d-b                  C. b-a-c-d-e                  D. b-c-a-e-d
