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.
【小题1】How do human genomes read according to the passage?
| A．Only from left to right. | B．Only from right to left. |

| 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 |
| A．specialists in the field | B．general readers |
| C．natural scientists | D．readers with academic background |
| 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 |

Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.
1. Most historians hold that the Chinese invented fireworks in the 9th century when they
discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.
2. In May of 1886, a law led John Pemberton, a pharmacist（药剂师）, to rewrite the formula(配方) for "Pemberton’s French Wine Coca,” his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world –wide drink came into being.
3. During World War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven(微波炉). While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.
【小题1】The right time order of the three inventions, according to the passage, should be_________.
| A．fireworks, the microwave and Coca-Cola |
| B．fireworks ,Coca-Cola and the microwave |
| C．Coca-Cola , fireworks and the microwave |
| D．the microwave, Coca-Cola and fireworks |
| A．looking for a way to melt his chocolate |
| B．trying to know how a magnetron could cook |
| C．working to know how the magnetron works |
| D．asked to invent a restaurant microwave oven |
| A．Experiments make great inventors of our time. |
| B．Nothing is impossible if one tries each day. |
| C．Inventors come out of hard work at any time. |
| D．A small incident may lead to a great invention. |
| A．What great inventions they are! | B．Inventions from Three Countries. |
| C．Stories of Accidental Inventions. | D．The Human Inventions of time. |
