　　 Scientists have uncovered the exact difference between man and mouse. Teams of scientists from around the world will publish today the draft (草图) genome (基因组) of the mouse, which enables them for the first time to compare another mammal’s entire DNA directly with that of humans.

The similarities are far greater than the differences-man and mouse share a common ancestor that lived more than 70 million years ago-which has allowed scientists to find treatments for a good many human diseases.

British members of the project say the draft mouse genome, published in the journal Nature, has provided the “phrasebook” for scientists to translate the language of the human genome.

“The entire biomedical research community can for the first time fully use this resource to deal with human diseases. They will now have powerful tools that will serve them for many years to come,” said Dr. Jane Rogers at the Welcome Trust Institute in Cambridge, which did 20 percent of the work.

Comparisons show almost every gene in the mouse has a corresponding(对应的) gene in humans - a 99 percent similarity that should help to find how each human gene works. Already the work has been able to show that man and mouse each have about 30, 000 genes, yet only 300 or so are unique to either species, increasing the value of the lab mouse as a “model” for human genetics.

This is an extraordinary milestone. For the first time we have an opportunity to see ourselves in an evolutionary (进化论) mirror. The mouse genome stands for a very important chapter in the lab notebook of evolution. By taking away genes to create sick mice, scientists have been able to reproduce a number of human disorders. Knowing the entire genomes of humans and mice will enable them to employ the technique more widely, leading to a rapid development in the understanding of illnesses.

It often happens that a number of applicants with almost identical qualifications and experience all apply for the same position. In their educational background, special skills and work experience, there is little, if anything, to choose between half a dozen candidates. How then does the employer make a choice?

There are many arguments for and against the interview as a selection procedure. The main argument against it is that it results in a wholly subjective decision. As often as not, employers do not choose best candidates, they choose the candidate who makes a good first impression on them. Some employers, of course, reply to his argument by saying that they have become so experienced in interviewing staff so that they are able to make a sound assessment of each candidate’s likely performance. The main argument in favor of the interview and it is, a good argument--is that an employer is concerned not only with a candidate’s ability, but with the suitability of his or her personality for the particular work situation. Many employers, for example will ignore occasional mistakes from their secretary provided she has a pleasant personality, character and social ability. Unfortunately, both for the employers and applicants for jobs, there are many people of great ability who simply do not interview well. There are also, of course, people who interview extremely well, but are later found to be very unsatisfactory employees. Candidates who interview well tend to be quietly confident, but never boastful; direct and straightforward in their questions and answers; cheerful and friendly, but never over familiar; and sincerely enthusiastic and optimistic. Candidates who interview badly tend to be at either end of the spectrum(范围) of human behavior. They are either very shy or overconfident. They show either a lack of enthusiasm or an excess of it. They either talk too little or never stop talking. They are either over-polite or rudely abrupt.

69. We can infer from the passage that an employer might tolerate his secretary’s occasional mistakes, if the latter is _____.

A. direct　　　 B. cheerful　　　 C. shy　　　 D. capable

70. What is the author’s attitude towards the interview as a selection procedure?

A. Unclear　 　B. Negative　 C. Objective (客观的)　 　D. Indifferent (漠不关心的)

71. According to the passage, people argue over the interview as a selection procedure mainly because they have _____.

A. different selection procedures　　　　 B. different purposes in the interview

C. different standards for competence　　 D. different experienced interviews

72. The underlined word “subjective” in the second paragraph means_____.

A. based on personal taste　 B. existing outside the mind　 C. reasonable 　D. unreliable

A special education teacher and former police officer was honored by President Barack Obama at the White House as the 2009 National Teacher of the Year for his innovative(创新的)approach, community focus, and teamwork with other teachers. “In a global economy where the greatest job qualification isn't what you can do, but what you know, our teachers are the key to our nation's success,” President Obama stated.

Mullen, a ninth-through-twelfth-grade special education teacher at the ARCH School in Connecticut, is the 59th National Teacher of the Year. Mullen's goal is to provide passion, professionalism(职业精神), and perseverance as an educator. “A teacher can receive no greater reward than the knowledge that he or she helped recover a lost student,” Mullen remarked. He will travel for one year as a full-time national and international spokesperson for education beginning June 1, 2009.

The National Teacher of the Year Program focuses public attention on teaching excellence and is the oldest and most famous national honors program for teachers. “ACEI is a proud participant in the selection process for the National Teacher of the Year, and we are pleased to see Mr. Mullen is a dedicated individual who possesses a wealth of talents and skills as a teacher. His devotion to young people, however, reaches beyond the call of duty. Mr. Mullen extends himself to adviser and guides children who need to know that they are not forgotten and that they, too, are unique and special,” stated ACEI Executive Director Diane Whitehead.

ACEI is one of 15 national education organizations that select the National Teacher of the Year from among the state teachers of the year, including those representing the District of Columbia, the Department of Defense Education Activity, and five U.S. extra state departments.
