We are all interested in equality, but while some people try to protect the school and examination system in the name of equality, others, still in the name of equality, want only to destroy it.

Any society which is interested in equality of opportunity and standards of achievement must regularly test its pupils. The standards may be changed—no examination is perfect—but to have tests or examinations would mean the end of equality and of standards. There are groups of people who oppose this view and who do not believe either in examinations or in any controls in school or on teachers. This would mean that everything would depend on luck since every pupil would depend on the efficiency, the values and the purpose of each teacher.

Without examinations, employers will look for employees from the highly respected schools and from families known to them －a form of favoritism will replace equality. At the moment, the bright child from an ill-respected school can show certificates to prove he or she is suitable for a job, while the lack of certificate indicates the unsuitability of a dull child attending a well-respected school. This defending of excellence and opportunity would disappear if examinations were taken away, and the bright child from a poor family would be a prisoner of his or her school’s reputation(聲譽), unable to compete for employment with the child from the favored school.

The opponents of the examination system suggest that examinations are an evil force because they show differences between pupils. According to these people, there must be no special, different, academic class. They have evensuggested that there should be no form of difference in sport or any other area all jobs or posts should be filled by unsystematic selection. The selection would be made by people who themselves are probably selected by some computers.

1.The word “favoritism” is used to describe the phenomenon that _____.

A. children from well-respected schools tend to have good jobs

B. bright children also need certificates go get satisfying jobs.

C. poor children with certificates are favored in job markets

D. children attending ordinary schools achieve great success

2.What would happen if exams were taken away according to the author?

A. Schools for bright children would lose their reputation.

B. There would be more opportunities and excellence.

C. Children’s job opportunity would be affected by their school reputation.

D. Children from poor families would be able to change their schools.

3.The opponents of the examination system will agree that _____.

A. computers should be selected to take over many jobs

B. jobs should not be assigned（分配）by systematic selection

C. special classes are necessary to keep the school standards

D. schools with academic subjects should be done away with

4.The passage mainly focuses on _____.

A. examination and equality B. schools and certificates

C. opportunity and employment D. standards and reputation

If there is one person who has left a deep impression on me, it’s my teacher Mrs. Pathak who was my class teacher for three years. In my childhood, how I wished I had a mother or a sister like her. One moment she could be tough (嚴厲的) and strict, another moment caring and compassionate (富有同情心的).

She always encouraged us to tell the truth. For instance, if one had not done the homework, he need not lie. She allowed us to make mistakes, saying we couldn’t be perfect all the time, but we should try.

Another thing she taught me early on was punctuality. She set a good example with her own behaviour. She was always on time, so we students tried our best to be on time.

She surprised us with her sense of humour. Her classroom teaching was always humorous. After class, she talked to us and told us jokes.

We really felt free to ask questions and Mrs. Pathak would give the answers. If she did not know — there had been some occasions (場合) — she would say so. We all then tried to find out the answers. Whoever came up with the answer was appreciated and given the due credit (應有的稱贊). Now I sometimes wonder whether Mrs. Pathak was pretending just to encourage us to explore and find answers by ourselves.

1.According to the passage, which of the following is NOT suitable for describing Mrs. Pathak?

A. Tough. B. Humorous.

C. Compassionate. D. Careful.

2. The underlined word “so” in the last paragraph means that _____.

A. the answers were not right

B. she didn’t know the answers

C. the answers were correct

D. she would give the answers

3. In the author’s opinion, why didn’t Mrs. Pathak give the answers to the questions sometimes?

A. Because she didn’t like answering the questions.

B. Because she didn’t know the answers to the questions.

C. Because she wanted the students to find them out by themselves.

D. Because she thought the students knew the answers already.
