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, which makes it longer than 5,000 volumes the size of this book, or 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 a century. If I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube. This is an enormous document. A huge volume, a cook book of great length, and it all fits inside the extremely small nucleus (核) of a tiny cell that fits easily upon the head of a pin.

The idea of the genome as a book is not, strictly speaking, even a metaphor (比喻), 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 letters into a large dictionary of meanings through the order of their groupings. So is a genome. The only complication is that all English books read from left to right, while some parts of the genome read from left to right, and some from right to left, though never both at the same time.

While English books are written in words of different lengths using twenty-six letters. Genomes are written entirely in three-letter words, 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 conditions it can both photocopy itself and read itself.

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

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 and alphabet of four letters

       D. is smart enough to read and take photos of itself

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 academic background

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

 

On a hot African morning, Leila was lying on her stomach and an elephant was walking towards her. Leila waited. Then she pushed the button on her camera. “And I got my best photo of an elephant ever, by lying under my car,” Leila explained. “I wanted to get close to the elephants, but of course this was dangerous; they had their babies with them. So every morning I used to park my car in the open near the path (小道). They used to take the same path every morning when they left the water hole. After a week, they were used to seeing my car. So the next morning, I lay under it and got my photo!”
Many of the best wildlife photos come from good planning. In Africa, photographers set up their hides (隐匿处) near water holes. They also set up hides near forest paths, as animals use the same paths every night. For bird-watching, many lakes have hides. Inside the hides, bird-watchers can watch all day in the shade (荫处) out of the wind and rain.
Good wildlife photos are needed for books, postcards, magazines and newspapers. But a success rate of 1 in 20 is good.
