Next Stop: Planet Mars
Fly me to the moon? That’s not far enough. On September 14, 2011, NASA released designs for a superrocket, the Space Launch System (SLS). This time the final destination will be Mars.
The SLS is a huge, liquid-fuelled rocket. If it is fully developed, it will be the most powerful rocket ever built. Its lift capability will be much bigger than that of the space shuttle of Saturn 5, the rocket that sent the Apollo missions to the moon.
NASA is planning to launch its first unmanned test flight in 2017. It is hoped that the first crew will fly in 2021 and astronauts will make it to a nearby asteroid(小行星) in 2025. NASA hopes to send the rocket and astronauts to Mars from the asteroid by the 2030s, according to the Associated Press (AP).
NASA used liquid rockets to send Apollo, Gemini and Mercury into space, but later changed to solid rockets boosters(助推火箭) because they were cheaper. Tragically, however, a booster flaw(缺陷) caused the space shuttle Challenger to crash in 1986. The new project plans to return to liquid fuel.
According to AP, the rockets will at first be able to carry 77 to 110 tons of payload(净载重量). Eventually they will be able to carry 143 tons into space, maybe even as many as 165 tons, NASA officials said. By comparison, the Saturn 5 booster could lift 130 tons and the space shuttle just 27 tons.
However, unlike reusable shuttles, these powerful rockets are mostly one use only. New ones have to be built for every launch. This will be very costly.
NASA estimates that it will cost about $3 billion (19 billion yuan) per year, or $18 billion until the first test flight in 2017. NASA hopes to make money by allowing private companies to send astronauts to the International Space Station like giant taxi services, so that the program can be “sustainable”.
“This is perhaps the biggest thing for space exploration in decades,” said Senator Bill Nelson, a former astronaut. “The goal is to fly humans safely beyond low-Earth orbit(轨道) and deep into outer space where we cannot only survive, but one day also live.”
What is the outstanding feature of the SLS?

A.It’s equipped with an advanced control system.
B.It’s the first unmanned space shuttle in the world.
C.It’s the only vehicle that can fly astronauts to the moon.
D.It can send a lot more goods and passengers into space.

What is Saturn 5?

A.An aircraft that had a deadly flaw and crashed in 1986.
B.A series of rockets that once sent astronauts to the moon.
C.An unmanned space shuttle that was once famous in the world.
D.A kind of launch vehicle that will be used to carry astronauts to Mars.

NASA plans to use liquid fuel in the new project because ______ than solid rockets boosters.

A.it is less costly
B.it is much safer
C.it can last longer
D.it is more environmentally friendly

According to NASA’s schedule, it will take ______ years to fully complete the SLS program.

A.about 6 B.about 10
C.less than 14 D.more than 19

It can be inferred from the passage that ______.

A.the SLS program is planning to make reusable rockets
B.the goal of the SLS program is to enable humans to live on the moon
C.the US government may not have provided enough money for the SLS program
D.NASA will use SLS as a space taxi between the Earth and Mars

Once again, I had run away and really did not know why. I walked out of the gate to go to school and then kept walking, and walking, and walking. I was 11years old. It was almost dark; I was tired, cold, and all alone. I had not eaten all day and was afraid to turn myself over the police. I knew I would receive another beating once I returned to the Children’s Home Society. There was nothing for me to do, except keep on walking.
As darkness fell, I entered the darkened area in a city park sat down on a wooden bench hoping to avoid the police cars. It was cold and I began to tremble uncontrollably. All was quiet except for the passing cars in the distance.
“Well, hello young man.” A voice came from behind me. I jumped, almost falling off the park bench. My heart was beating ninety miles per hour. I gasped and I could hardly catch my breath. I looked up and saw a woman standing behind me in the shadows.
“You look cold and hungry,” she said. She took off her scarf, wrapped it around my shoulders and asked me to follow her. We walked about twenty feet, and then stopped under one of the park streetlights.
She held out her hand and said, “Here, you take this letter.” Seeing nothing in her hand., I stood still.
“Reach out and take the letter from my hand,” she insisted. Slowly I reached out, acting as though I was taking something from her hand. “Now hold the paper tightly and take it to any store owner,” she instructed.
I closed my thumb and finger as though I were grasping the letter and began walking toward Five Points. Several blocks down the road, I came to a store with a woman sitting behind a counter. I opened the door, walked in, and stopped directly in front of her. Very slowly I held out my hand toward her. I watched her face to see if she might think I was crazy or something.
She reached out and as her hand touched mine, I opened my tightly closed fingers and stood there waiting. She pulled back, smiled, and looked down at her hands.
She immediately turned and walked to the back of the store. After a while, the woman returned holding a paper plate.
“Here is something for you to eat.” She smiled and signaled to me to eat. Within two or three minutes, I downed the entire plate of food and several Coca Colas.
Before I left, she held out her hand and asked me to take the letter. Again seeing nothing, I held out my hand and closed my thumb and finger as though I were taking something from her. Tightly grasping nothing more than air, I walked out into the street and headed back to the park. The old woman was still there.
“It is really magic. Can I have the letter so I can be magic too?” I asked her.
She reached out, took my hand, and opened my tightly closed fingers. Whatever was being held between my fingers, she took and placed into her apron pocket. “Would you help someone if they were hungry?” she asked me.
“Yes Ma’am.”
“Would you help someone if they were hurt, cold or scared?”
“Yes Ma’am. I would be their friend.”
“You are a very lucky little boy. You will never need the magic letter,” she responded.

An idea that started in Seattle's public library has spread throughout America and beyond. The idea is simple: help to build a sense of community in a city by getting everyone to read the same book at the same time.
In addition to encouraging reading as a pursuit (追求) to be enjoyed by all, the program allows strangers to communicate by discussing the book on the bus, as well as promoting reading as an experience to be shared in families and schools. The idea came from Seattle librarian Nancy Pearl who launched (发起)the "If All of Seattle Read the Same Book " project in 1998. Her original program used author visits, study guides and book discussion groups to bring people together with a book, but the idea has since expanded to many other American cities, and even to Hong Kong.
In Chicago, the mayor appeared on television to announce the choice of To Kill a Mockingbird as the first book in the "One Book, One Chicago" program. As a result, reading clubs and neighborhood groups sprang up around the city. Across the US, stories emerged of parents and children reading to each other at night and strangers chatting away on the bus about plot and character.
The only problem arose in New York, where local readers could not decide on one book to represent the huge and diverse population. This may show that the idea works best in medium-sized cities or large towns, where a greater sense of unity(一致)can be achieved .Or it may show that New Yorkers rather missed the point, putting all their energy and passion into the choice of the book rather than discussion about a book itself.
As Nancy points out, the level of success is not measured by how many people read a book, but by how many people are enriched by the process or have enjoyed speaking to someone with whom they would not otherwise have shared a word.
What is the purpose of the project launched by Nancy?

A.To invite authors to guide readers.
B.To encourage people to read and share.
C.To involve people in community service.
D.To promote the friendship between cities.

Why was it difficult for New Yorkers to carry out the project?

A.They had little interest in reading.
B.They were too busy to read a book.
C.They came from many different backgrounds.
D.They lacked support from the local government.

According to the passage, where would the project be more easily carried out?

A.In large communities with little sense of unity
B.In large cities where libraries are far from home
C.In medium-sized cities with a large population
D.In large towns where agreement can be quickly reached

The underlined words “shared a word” in Paragraph 5 probably mean .

A.exchanged ideas with each other
B.discussed the meaning of a word
C.gained life experience
D.used the same language

According to Nancy, the degree of success of the project is judged by .

A.the careful selection of a proper book
B.the growing popularity of the writers
C.the number of people who benefit from reading
D.the number of books that each person reads

MONDAY:I'm officially a Facebooker. I find a few people I used to know and I've soon got seven friends. I've never felt so popular! I wonder if my old university flatmate Steve is on here…What do you know! He is! Maybe Facebook has its uses.

There are some topics that readers never grow bored with, and the search for a suitable partner(伴侣) is one of them. Pride and Prejudice(傲慢与偏见)by Jane Austen, first published in 1813, tells the story of five young women, all of whom are looking for a husband. In order to fully understand the novel, the readers must know that at the time when Jane Austen was writing, if a family was not rich, the daughters needed to marry well in order to live a comfortable, independent life. That is the reason why Mrs Bennet, the mother of the five girls, is so eager to have her daughters married.
The heroine of the story is Elizabeth Bennet, and as in all good romantic novels, she and Darcy, the man she finally marries, remain separate until the very end of the story. The wealthy Darcy is a proud, unsociable man, and when Elizabeth hears that he has insulted(侮辱) both her and her family, she dislikes him very much. Poor Darcy then falls head over heels in love with Elizabeth, and has to work terribly hard to persuade her to change her mind about him. He succeeds of course, and they live happily ever after.
Set at the turn of the 19th century, the novel is still attractive to modern readers. It has become one of the most popular novels and receives great attention from literary scholars(学者).Modern interest in the book has resulted in a number of dramas(戏剧)and a lot of novels and stories modeling(模仿) after Austen’s memorable (难忘的)characters or themes. To date, the book has sold some 20 million copies worldwide.
Jane Austen is rightly famous for her style. Her sentences have a wonderful rhythm(韵律), and she makes such clever, true comments about people. It is not surprising that Pride and Prejudice has lasted.
In the 19th century, a poor girl in Britain was often encouraged to.

A.master the skills of writing B.marry the one she loved
C.change her life by marrying rich D.obey her parents

What do we know about Elizabeth and Darcy?

A.They both come from poor families and wish to marry rich.
B.They’ve experienced ups and downs but get married in the end.
C.They get separated from each other shortly after being married.
D.Darcy falls over and gets hurt but Elizabeth still loves him.

According to the passage, Pride and Prejudice _________.

A.inspired many other novels and many plays have been produced based on it.
B.was first published in 1813 and sold 20 million copies soon
C.tells a sad love story which moves generations of readers
D.is set at the turn of the 19th century and not well received worldwide

Winter begins in the north on December 22nd. People and animals have been doing what they always do to prepare for the colder months. Squirrels (松鼠), for example, have been busy gathering nuts from trees. Well, scientists have been busy gathering information about what the squirrels do with the food they collect.
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.
The study done by Rob Swihart and Jake Goheen is to ________.

A.find out the living conditions for squirrels
B.do something to get rid of squirrels
C.learn squirrels’ influence on black walnut trees
D.save the forests in the American state of Indiana

The difference between gray squirrels and red squirrels mainly lies in ________.

A.the way they gather the walnut
B.the place they store the walnuts
C.the time they have winter sleep
D.the place they have winter sleep

When Professor Swihart says “death traps for seeds”, he actually means that ________.

A.nuts above the ground will not develop into plants
B.red squirrels eat more nuts than gray squirrels
C.gray squirrels and red squirrels will have severe fights
D.seeds can be traps for other animals in the forest

According to the passage, which of the following is true?

A.Gray squirrels do more harm to the forest than red squirrels.
B.Red squirrels and gray squirrels have helped the spread of walnut trees.
C.The cleaning of forest land benefits red squirrels directly.
D.The black walnut is equally attractive to both gray and red squirrels.
