Do you want to live another 100 years or more? Some experts say that scientific advances will
one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate.”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”
67. By saying “ we are knocking at the door immortality”, Michael Zey means_____.
A. they believe that there is no limit of living
B. they are sure to find the truth about long living
C. they have got some ideas about living forever
D. they are able to make people live past the present life span
68. Donald Louria’s attitude toward long living is that_____.
A. people can live from 120 to 180
B. it is still doubtful how long humans can live
C. the human body is designed to last about 120 years
D. it is possible for humans to live longer in the future
69. The underlined “ it” (Para. 4) refers to_____.
A. a great push
B. the idea of living beyond the present life span
C. the idea of living from 200 to 300
D. the conservative estimate
70. What would be the best title for this text?
A. Living longer or not
B. Science, technology and long living
C. No limit for human life
D. Healthy lifestyle and long living

请阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该选项的标号涂黑。
Going back to school is a very exciting event for my two boys. It means getting new school bags and books, and seeing friends again after the summer holiday.
My oldest son, 9-year-old Salem, asked me several times where we would go to buy a backpack, while my other son, 6-year-old Abdullah, asked what school would be like this year.
For the last three years, school was a nightmare for many children and their parents as violence increased and there were more attacks on schools and teachers. As a result, many parents prevented their children from going to school. One of six children in this country did not attend primary school in 2009. Many kids who did attend school were accompanied by a parent for the entire day to make sure nothing happened to their children.
For poor families or those with large families, back to school can be an expensive time. The government gives some help to those living in poor neighborhoods, and school bags, note books and other items(商品) are given for free.
Most of the merchants who sell notebooks and pens now sell their products out on the street instead of in stores. They sit on the ground and lay their items on the ground or they have a small table to sell their goods.
The bags cost between $10 and $20, while clothes and shoes cost between $20 and $30. I found all the things I needed for my sons and even bought something for myself. I spent about $50 on each of them, including school uniforms.
At the end of the day, we returned to our home carrying many shopping bags filled with items that made my children happy and excited to go back to school. I just hope this school year will be a peaceful one.
56.The author’s children are ________ to go to school.
A. eager B. afraid C. unwilling D. surprised
57.The underlined word “nightmare” is the closest in meaning to ________.
A. fantasy B. dream world C. prison D. terrible situation
58.Many children are not going to school mainly because of ________.
A. the terrible education system B. security problems and poverty
C. parents’ distrust in schools D. the government’s inability
59.As a parent, the author ________.
A. is unable to afford his kids’ schooling B. is unwilling to send his kids to school
C. hopes his kids have a happy school life D. complains school education costs too much


Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.
72. The author thinks the golf is resource-hungry because of the following EXCEPT that _____.
A. Golf wastes large areas of countryside
B. Golf runs out of much water
C. Keeping golf court in good condition needs too much energy
D. Golf is bad for people’s health
73. According to the passage, which of the following is an environment-friendly sport?
A. swimming in the pool B. hiking in the hills
C. playing basketball in the gym D. motor racing in the desert
74. The reason why the author uses power walking as an example mainly is that ______.
A. it improves our health B. it is an outdoor sport
C. it uses fewer resources D. it is recommended by experts
75. The passage is developed mainly by _____.
A. examples and explanation B. comparison and persuasion
C. facts and descriptions D. figures and conclusion


Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.
“We’ve been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO2 levels. And we’ve been able to record this increasing quantity of atmospheric CO2 into the ocean.”
Scientists expected that as atmospheric CO2 increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
“As carbon dioxide dissolves (溶解) in the water, or seawater in this case, it forms a weak acid (酸), carbonic acid, ” Dore explains. “And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic.”
The seawater Dore and his colleagues have analyzed confirms what the theory predicts.
The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
“It’s important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic.”
68. What can be the best title of the passage?
A. Sea Life Facing Danger B. Scientist Researching Seawater
C. Oceans Becoming More Acidic D. Climate Change Affecting Seawater
69. Which of the following shows the process of the impact of atmospheric CO2 on sea life?
a. Sea life is endangered.
b. CO2 goes into the surface water.
c. The ocean chemistry is affected.
d. CO2 decreases the pH and makes the seawater more acidic.
e. CO2 levels in the atmosphere go up.
A. a→b→c→d→e B. e→b→c→d→a
C. a→e→c→d→b D. e→d→c→b→a
70. Scientist Robert Dore came to the conclusion based on ________.
A. his research and analysis B. the expectation of other scientists
C. some former theory D. a major cause of climate change
71. What does the passage want to tell us most?
A. It takes time to make a scientific study.
B. Atmospheric CO2 is doing harm to sea life.
C. Robert Dore is a committed and serious scientist.
D. Measures should be taken to prevent the potential catastrophe.

More teachers are starting off the school year with letters to parents and students to introduce themselves and set a tone (基调) for the year. The letters are a good way to start positive communication with parents, several teachers told Education World.
“I think it’s professional, ”said Dorothy Peselli, an English teacher at Sparta High School in Sparta, New Jersay, Peselli, who gives out the letters the first day of school, told Education World. “It gives parents an image of you as a professional. If you start communication off in a positive manner, you will have the parents on your side when you need them.”
In her letter to parents, Peselli encourages them to call or e-mail her with specific concerns about their children. “I want to work as a team to make sure that your child becomes an independent lifelong learner,” Peselli wrote to parents last September. She also telephones the parents of all her students at the beginning of the year.
Peselli includes with the letter a classroom handbook (手册) listing plans and rules. And she requires that both parents and students read and sign statements (included in the letter) when they read the handbook. The student letter also lists needed supplies and gives encouragement. “Please come to class ready to work and learn. This will be an exciting year for all of us,” it says.
Last year, Peselli taught at a different high school and parents there were “shocked”, but appreciative, that she had so much contact with them. “I received roses and a thank-you note from one boy and his mother,” Peselli said. She wished her own children’s teachers would take the time to write notes as well. “I never got a letter home from any of my daughter’s high school teachers.” she said, “It would be nice to know the background of some of the people who are teaching my daughter.”
60. We may learn from the text that ______.
A. most teachers are writing letters to parents and students
B. the handbook is used to list supplies and give encouragement
C. Peselli believe it important for teachers to exchange information with parents
D. Peselli mainly introduces her background and teaching experiences in the letters
61. The underlined word “it” in the fourth paragraph refers to _____.
A. the handbook B. the requirement
C. the school D. the letter
62. We can infer from the last paragraph that ______.
A. parents were satisfied with Peselli’s way of working
B. Peselli means to surprise parents by writing students
C. Peselli seemed to be popular among boy students
D. all Peselli’s children are studying in high schools
63. The purpose of the text is to ______.
A. introduce an English teaching method
B. give advice on how to teach students
C. encourage teachers to keep in touch with parents
D. show us how Dorothy Peselli makes teaching plans
