Imagine that the genome (基因组) is a book.The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels.There are one billion words in the book, as long as 800 Bibles; if I read the genome out to you at the rate of one word per second for eight hours a day, it would take me centuries; if I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.This is a huge volume, a book of great length, but it all fits inside an extremely small cell nuclear(细胞核) that fits easily upon the head of a pin.
The idea of the genome as a book is not, strictly speaking, even a metaphor.It is true to a great extent.A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings.So is a genome.The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time.
While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules (分子).
The genome is a very clever book, because in the right condition it can both photocopy itself and read itself.
【小题1】How do human genomes read according to the passage?___________

A.Only from left to right.
B.Only from right to left.
C.From both directions at the same time.
D.From one direction at a time.
【小题2】We can learn from the passage that the human genome ________.
A.is as long as the River Danube
B.can be easily placed on the head of a pin
C.is coded with an alphabet of four letters
D.is smart enough to read and take photos of itself
【小题3】It can be concluded that the passage is mainly written for ______.
A.specialists in the field
B.general readers
C.natural scientists
D.readers with professional knowledge
【小题4】The real purpose of the author’s comparison of the genome to a book is _____.
A.to focus on the differences between the two
B.to lay emphasis on the similarities between the two
C.to simplify the concept of the human genome
D.to give an exact description of the human genome

I am trying to muster(鼓起)the courage to toss away my mobile phone to enjoy a more peaceful and ring –free life.

Can you imagine not having your mobile phone? In our high-tech, in-a-hurry age, a cell-free life is a hard concept to swallow. Our mobile phones can now access the Internet, and many people feel the need to express their every thought on their blog pages. If I gave up my cellphone, people would think I was mad.

I wish I had the strength to toss away my technology . I have an office phone, a home phone, e-mail and if people want to contact me. they can. If I’m out, people can leave a message. Do they really need to find me 24/7 ? However, I’m a bit like Frodo in the movie Lord of the Rings. The power of the ring is too strong and I can’t let it go.

Mobile phones have become necessary tools in our busy life. For most people , they hold all contacts and many of us don't write up address books any more. The latest phones carry our music, pictures, movies and everything else. We feel lost without this device and when we do misplace it , we feel cut off from our fellow,

“Where have you been?” said a friend, who saw me a week after I lost my cell, “I tried calling you , but you disappeared. You disappeared off the face of the Earth。” See, when you don’t have a mobile phone, you don’t exist.

I’m not really going to toss my mobile phone away, in fact. We humans are such social animals and mobile phones serve us well. So in 2009, I’ve dicided not to serve my mobile phone. Like all machine, I can always turn it off.

I went into Harrods in London (a huge department store I am sure you have heard of) to buy some Minton china plates for a wedding anniversary which was to be a group gift from friends to other friends in Geneva.

Having only 30 minutes between meeting. I whizzed there in a taxi from the office and battled through the milling people on the 2nd day of the sales on the ground floor up to the 5th to the china department. There was a man standing there who was obviously a sales person who I rushed up to and asked if he had this particular china in stock and if it would take long to wrap, etc. He was amazing. He got the plates in seconds, wrapped them up and asked me if I wanted a store card, to which I replied no, because I lived in Switzerland, to which he replied asking if, as I lived abroad, would like a tax rebate form(退税表). After that he showed me what to do, produced a map of the store and told me where I should go for the formalities(程序). That was fabulos! I thanked him and said what wonderful service he had given me. I even asked if he gave this to everyone, to which he answered: “I’m just doing what is required at Harrods”. With that, a tall man in a grey suit approached me and offered his hand to shake mine saying, “Can I introduce myself? I am the Chief Executive of Harrods and what an interesting conversation I have just heard…” He had been wandering through the store (as you should do as a hands-on CEO) and had overheard me thanking this salesman, whose face, I can hardly

describe, was frozen in a mixture of delight awe and astonishment!

Can you imagine the salesman going home to his family and friends recounting what the CEO spoke to him after overhearing him being praised by a customer?

A. “I’m an honest man.”           B. “I must obey the rules.”

C. “Harrods is strict with its employees.”    D. “Anybody will receive our good service.”

59. As soon as she bought what she wanted, the writer________.

A. went to a meeting.            B. flew back to Geneva

For my grandmother's 70th birthday, my family and I visited South Korea. While there, I was attentive to Korean high schools and students.

I was surprised by how different Korea's public high schools are from America's. Korean high schools can be all-girls, all-boys or co-ed (男女同校的)unlike our standard co-ed high schools. There are three grades: “go 1(10th) ”, “go 2” (1l th) and “go 3” (12th). “Go”is the first syllable of the word “go-deung –hakkyo”, which, simply translated, is “high school”.

In America, unless you want to go to a private school, you don't have to take an entrance exam. In Korea, however, students must take a test to get in because of the many choices of schools.

Another difference I couldn't help but notice was the students' appearance. With very few exceptions, all wear uniforms. A name tag (标牌)with the student's name, grade and homeroom number must also be worn. Girl's skirts can't be above the upper part of the knee, and it is forbidden to dye (染)your hair or wear accessories (装饰品)except small earrings. There are strict regulations for appearance to achieve neatness, and it seems the only freedom students have is with their choices of hair style, socks and shoes.

The final difference was the setup of the classes. There may be 40 students in a classroom, but the number can be less or even more, depending on the population of the town or city. Although there are many students per classroom, they are very close, which I think is a result of not changing classrooms for different subjects. There are no levels in the subjects and the teachers are the ones who switch classrooms. They just have ten-minute breaks between subjects. In each class, students are ranked by their grades. This causes strict competition, and Korean students do a lot of studying. To help them, all schools have extra study classes after school. One other fact that helped me appreciate living in America is that Koreans have school on Saturdays. Although it's only a half day, I think I speak for most Americans when I say we could never imagine ourselves in school on a Saturday.

Korea's public high schools are clearly different from America's. I had imagined them to be just like our schools, but now I have a clear picture of how different they are.

59. How many main differences are mentioned between Korea's public high school and America’s?

A. 3.                               B. 4.                   C. 5.                   D. 6.

60. It seems that the writer  _______ .

A. is familiar with the education system of high schools in Korea

B. is fond of Korean students' appearance

C. prefers the high school life of America to the one of Korea

D. feels it common to have lessons on weekends

61. What does the underlined word "setup" in paragraph 5 probably mean?

A. Arrangement.        B. Size.               C. Number.         D. Outline.

62. According to the rules, the students of Korea can _______  .

A. go to different high schools without exams  B. wear any clothes except uniforms at school

C. attend different classes as they like               D. have different hair styles
