Over a period of time, many habitats (栖息地)change with respect to the types of plants and animals that live there. This change is known as succession.
Succession occurs because plants and animals cause a change in the environment in which they live. The first weeds and grasses that appear on a bare field, for example, change the environment by shielding the soil from direct sunlight. As these plants spread, the ground becomes cooler and more moist than it was originally. Thus, the environment at the ground surface has been changed. The new surface conditions favor the sprouting(产生)of shrubs. As shrubs grow, they kill the grasses by preventing light from reaching them and also enhance (增加)the soil. Pine seedlings (苗)soon take hold and as they grow, they in turn shade out the shrubs. They are not able to shade out oak and hickory (山核桃)seedlings, however, that have found the forest floor suitable. These seedlings grew into large trees that eventually shade out the pines.The best title of this passage is _____.
A.The Importance of Weeds and Grasses |
B.The Success of Oak and Hickory |
C.How Environmental Habitats Change |
D.Animal and Plant Habitats |
It can be inferred (推理) from the passage that ______.
A.oak and hickory trees grow taller than pines |
B.weeds and grasses prefer cold climate |
C.pines and grasses can exist together |
D.birds encourage the growth of shrubs |
Which of the following is a stage of succession as described in the passage?
A.A forest cut down to build an airport. |
B.A flood washing away a crop of wheat |
C.Wild flowers growing in an unused parking lot |
D.Animals being tamed (驯服)by children |

Our listener question this week comes from Abdullahi Farah, who wants to know about the life and work of Doctor Benjamin Carson.
Doctor Carson is an internationally recognized doctor at Johns Hopkins Hospital in Baltimore, Maryland. He has been the director of Pediatric Neurosurgery at the hospital for twenty-five years. At the age of thirty-three, he became one of the youngest doctors in the United States to hold that position. And he was the first African-American to have that position at Johns Hopkins Hospital.
Ben Carson is known for his work as a brain surgeon for children. For example, in nineteen eighty-seven, he led a team of seventy doctors and nurses in an operation to separate two babies joined at the head. Earlier attempts by other surgeons on other babies had failed. Doctor Carson successfully performed the operation. Both babies were able to survive independently.
Doctor Carson has written four books. His first book, "Gifted Hands," tells the story of his life. Benjamin Carson was born in nineteen fifty-one in Detroit, Michigan.
As a boy, Ben was not a good student. In fact, he was the worst in his class. When his mother learned of his failing grades she asked her sons to read two library books every week. She limited the amount of time they watched television. And she told them to respect every person.
Ben Carson soon became the top student in his class. He went on to study at Yale University, one of the best universities in the country, and later to medical school at the University of Michigan.
Doctor Carson has received many awards and honors. Last year he received the nation's highest civilian honor. Former President George W. Bush presented Benjamin Carson with the Presidential Medal of Freedom at a ceremony at the White House.

All the wisdom of the ages and all the stories that have delighted mankind for centuries are easily and cheaply available to all of us within the covers of books. The most unfortunate people in the world are those who have never discovered how satisfying it is to read good books.
Reading is the pleasure of the mind, which means that it is a little like a sport: your eagerness and knowledge and quickness make you a good reader. Reading is fun, not because the writer is telling you something, but because it makes your mind work. Your own imagination works along with the author's or even goes beyond his. Your experience, compared with his, brings you to the same or different conclusions, and your ideas develop as you understand his.
Every book stands by itself, like a one--family house, but books in a library are like houses in a city. Although they are separate, together they all add up to something. They are connected with each other and with other cities. Books influence each other; they link the past, the present and the future and have their own generations, like families. Wherever you start reading, you connect yourself with one of the families or ideas, and in the long run, you not only find out about the world and the people in it but also you find out about yourself, too.
Reading can only be fun if you expect it to be. If you concentrate on books somebody tells you "you ought" to read, you probably won't have fun. But if you put down a book you don’t like and try another till you find one that means something to you, and then relax yourself with it, you will almost certainly have a good time and if you become, as a result of reading, better, wiser, kinder, or more gentle, you won't have suffered during the process.

In classrooms across the USA, students from different speech backgrounds give speeches in English. It is important to remember that the major goal of the speech is communication of ideas, not perfection of language skills. Therefore, as you listen to a speaker who is not fluent in the language, seek to understand what is being said by concentrating on the ideas of the message rather than on the specific words of the speaker. This may require a special kind of patience as well as the ability to take the perspective (视角) of the communicator. Perspective taking means that you can put yourself in the other person’s shoes. That is, you try to imagine what it would be like to give a speech in a foreign language to a group of native speakers of that language. Keep in mind that non-fluency is not linked to low intelligence or lack of education~ it is linked to experiences with the second language.
These guidelines can help you be a better listener in these situations.
1. Approach the speech with a positive attitude, and expect to understand.
2. Listen all the way through. Make special efforts to keep your mind from wandering in the middle of the speech. It may help to take notes.
3. Plan to give proper nonverbal (非语言的) feedback to prove your interest, patience, and support for the speaker.
4. Control your negative emotional responses. Let's face it, it is difficult to deal with linguistic barriers (语言障碍), and people often get disappointed or bored when there are language differences.
5. Do not laugh, even if the speakers do, at their language skills. Often they laugh nervously to relieve tension.
68. What is the main idea of this passage?
A. How to become a good listener.
B. How to become a good speaker.
C. We should take a positive attitude towards speech.
D. How to communicate with others

D. look at something from the point of others
70. What can we learn from the passage?
A. People should be strict with speakers speaking in a foreign language.
B. Taking notes helps keep your mind from wandering in listening to a speech.
C. Whenever the speaker is nervous, he laughs.
D. It's hard to concentrate when the speaker is not fluent.
71. What advice is given on listening to a speech?
A. Believing you can understand every word of the speech.
B. Showing your support for the speaker nonverbally.
C. Laughing when the speaker laughs at himself.
D. Commenting on the speech at times.
London: What could possibly he wrong with planting trees? The benefits are obvious: they firm the soil, absorb extra water and take carbon dioxide out of the atmosphere.
However, it now turns out that planting trees could add to global warming. Tree roots do a great job of keeping soil firmly on the ground and out of the wind's power. The problem is that some of those dust clouds play an important part in taking in carbon dioxide.
Huge dust storms blow out over the oceans from dry parts of North Africa and central Asia. Tons of dust are lifted and left as a thin film over the ocean surface.
Dust from China is carried east and left in the Pacific Ocean. If a tree-planting program there is successful and the dust supply reduced, the final result may be that less carbon dioxide gets locked away in the ocean.
Andy Ridgwell, an environmental scientist from the University of East Anglia, has spent the past few years studying dust and says his work shows clearly the complexity of the system and the importance of not working uselessly with it without understanding the results. For this reason the need is to focus on cutting carbon dioxide giving off rather than dealing with the land surface aimlessly.
An American scientist, Robert Jackson, has shown that when native grassland areas are occupied by trees, carbon is lost from the soil. "We are studying why the soil carbon disappears, but one theory is that trees do a lot more of their growing above ground compared to grasses, so less carbon goes directly into the soil from trees. " said Jackson.
In wet areas of the world, the gain from trees absorbing carbon dioxide above ground seems to be outweighed by the loss of carbon from the soil below ground.
Countries that plan to combat global warming by planting trees may have to think again. Solutions to environmental problems are often more complex than they first appear, and understanding the Earth's climate is a very great challenge.
64. People usually hold the opinion that _______.
A. huge dust storms can destroy carbon dioxide
B. huge dust storms can destroy the oceans on the earth
C. planting trees could reduce global warming
D. planting trees is the only way to control huge dust storms
65. Andy Ridgwell, the environmental scientist, believes that _______.
A. environmental problems are more complex than expected
B. trees shouldn't have been planted in dry places
C. dust plays a more important part than trees
D. carbon dioxide is harmful to everything
66. Robert Jackson's experiment proves that _______.
A. carbon can turn grass into dust
B. trees hold more carbon than grass
C. less carbon can make trees grow faster
D. grassland areas should be covered by forests
67. The underlined word "combat" in the last paragraph means _______.
A. learn about B. give up C. live with D. fight against
