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．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． |
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 |
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 |
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 |

Sometimes children do not do what their parents tell them to do. When this happens, a parent tries to help the child to do the right thing. When this does not work, the parent usually punishes the child.
There are many things that a parent can do. One thing that people have done is to spank (打屁股) the child. When a parent spanks a child, they will use their hand or a hard object to strike them on their bottom. This is meant to show the child that they have done something wrong.
One parent remembers being spanked when he was a child. His parents used a wooden spoon. When he spanked his own children with his hand, he saw that he put a red mark on his child’s leg. He never did that again.
One problem with spanking is that it teaches the child to hit someone when they do not like what the other person is doing. Another problem with spanking is that the parent is usually angry and can hit the child too hard. Sometimes parents will use spanking for everything and not try other ways to get the child to do the right thing.
Many parents are not sure of what to do instead of spanking. Some people think that their religion tells them that spanking is okay. Some think that the law lets them do it. The courts (法院) say that parents have the right to teach their children how to behave.
Other things should be tried before a parent decides to spank a child. Telling the child exactly what is wanted from them can be one thing. Giving a child more than one choice is another thing that can be tried. Getting down to the child’s level and taking a more child-friendly approach (方法) can help as well.
67. According to the passage, when children do something wrong, one thing that parents usually do to punish them is to ________.
A. strike them on the bottom

D. It makes parents try other ways to make the child do right.
69. Which of the following can best describe the writer’s attitude towards spanking?

There is one language that is used in every country in the world. The people who use it are young and old, short and tall, thin and fat. It is everybody’s second language. It is easy to understand, although you can’t hear it. It is sign language.
When you wave to a friend who is across the street, you are using sign language. When you smile at someone, you are saying, “I want to be friendly”, but you are not using speech. You are using sign language. When you raise your hand in class, you are saying, “Please ask me. I think I know the correct answer.”
Babies who can’t talk can point at things. They are using sign language. A policeman who wants to stop traffic holds up his hands. He is using sign language.
Many years ago, a French priest, Charles Michel de Epee, became interested in education for deaf people. He invented a finger alphabet (字母表). It is still in use. People can make the sign for letters and spell words with their hands, and deaf people can read and understand them. Soon there were schools for the deaf in many countries. The only university for the deaf is Gallaudet College in Washington, D.C.
Today, in the United States, there are special TV news programs for deaf people. The newsreader tells the news in sign language. At the same time, the words appear on the TV screen.
The actors in the Theatre of Deaf don’t spell every word. Sometimes they use hand signs. When they put two hands together, it means sandwich. They can make a roof with their hands when they want to show a house. One finger in front of an actor’s mouth can mean quiet. You can talk to people who are behind windows that are closed. And when you go swimming with your friends, you can have conversations under water.
How many hand signs do you use every day?

Dear Betty,
My roommate’s family wants me to celebrate Thanksgiving Day with them in their home. I accepted the invitation, and I’m excited about going, but I’m a little nervous about it, too. The social customs in my country are different from those here, so I’m a little worried about making mistakes.
Should I bring a gift, such as candy or flowers? Should I arrive on time or a little late? At the dinner table, how can I know which fork or knife to use? How can I let the family know that I’m thankful for their kindness?
Yours,
Knowing Nothing
Dear Knowing Nothing,
It’s a good idea to bring a gift when you go to a dinner party. Flowers are always welcome, or you can bring a bottle of wine if you know the family drink it.
You should arrive on time or five to ten minutes late. Don’t get there early. If you are going to be more than fifteen minutes late, you should call and tell them.
Try to relax at the dinner table. If you don’t know how to use the right fork, knife or spoon, just watch the other guests, and follow them. If you still have no idea of what to do, don’t be shy about asking the person next to you; it’s better to ask them than to be silently uncomfortable and nervous.
If you like the food, say so. Of course, you’ll thank the host and hostess for the meal and for their kindness. It’s also a good idea to send a card to thank them the day after.
Yours,
Betty

Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. The mountains are a splendid sight when viewed from the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure(基础设施)that must be maintained.
Unfortunately, these systems are starting to break down. It’s not just in Yosemite but in national parks around the nation.
Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with.
Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park service had to send water trucks to provide water for the visitors. Last month pipes almost broke again and roads had to be closed for a while.
Why hasn’t the National Park Service kept up the park repairs? There is a lack of money. The United States has 378 monuments, parks, and wilderness areas. Between three and four billion dollars are needed for repairs.
Yosemite is one national park that does have money for repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park.
A Sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowded park.
47. According to the text, the mountains in Yosemite look most splendid when they are appreciated from _______.
A. the bottom of the valleys B. the top of the mountains
C. the side of the mountains D. the edge of the valleys
48. National parks like Yosemite in the U.S. find it increasingly difficult to meet the need of visitors because ________.
A. the transport management needs improving
B. they spend too much on their service systems
C. their service systems frequently go out of order
D. they need help from environmental organizations
49. The main problem of Yosemite National Park is its _______.
A. rundown water pipes B. overcrowdedness C. lack of money D. narrow roads
50. According to the text, the Sierra Club is most likely to be ______.
A. an environmental group B. an information center
C. a travel service D. a law firm
