The African elephant, the largest land animal remaining on earth, is of great importance to African ecosystem(生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna(大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat.
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and under-bushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem.

Another man-made wonder of the United States was built long before the nation was established. About 900 years ago, the Ancestral Puebloan people built villages high in the walls of canyons in Colorado, where 600 cliff dwellings are now part of the Mesa Verde National Park.     
Visitors can stand at the top of the mesas and look into the dwellings almost hidden in openings of the rock walls. The Puebloan people cut small steps into the rock, which connected buildings containing hundreds of rooms.
The rock walls have protected the buildings from severe weather in the area; therefore, they remain mostly unchanged in the hundreds of years since they were built.
Our final man-made wonder is in the northwestern city of Seattle, Washington. The Space Needle was built as the central structure for the 1962 World's Fair.           
The 184-meter-tall structure was designed by Edward Carlson, which has a wide base on the ground, with its middle narrow and a large ring-like structure on top. The structure was meant to look like a "flying saucer," a vehicle that was popular in science fiction space travel stories.  The saucer includes an observation area and eating place. The restaurant slowly turns to provide visitors with a 360 degree view of Seattle.
The Space Needle, only costing about $4,500,000, was not very costly, and was designed and completed in about a year and opened on the first day of the World's Fair.
Today, the Space Needle is the most popular place for visitors to Seattle. And it remains the internationally known symbol of the city.

Each week, this program explains the many meanings of English expressions. Today’s expressions include a very important word—“heart”. We will try to “get to the heart of the matter” to better understand the most important thing about words and their stories. So “take heart.” Have no fear about learning new expressions. Besides, popular English words can be fun. There is no need for a “heavy heart.” Such feelings of sadness would only “break my heart,” or make me feel unhappy and hopeless.
Now, let us suppose you and I were speaking freely about something private. We would be having a “heart to heart” discussion. I might speak from “the bottom of my heart, ” or say things honestly and truthfully. I might even “open up my heart” to you and tell you a secret. I would speak with “all my heart”.
When a person shares her feelings freely and openly like this, you might say she “wears her heart on her sleeve”. Her emotions are not protected.
If we had an honest discussion, both of us would know that the other person’s “heart is in the right place.” For example, I would know that you are a “kind-hearted” and well-meaning person. And, if you are a very good person, I would even say that you have “a heart of gold.” However, you might have a “change of heart” based on what I tell you. Our discussion might cause you to change the way you feel about something.
But, let us suppose you get angry over what I tell you. Or worse, you feel no sympathy or understanding for me or my situation. If this happens, I might think that you have a “heart of stone.” And, if you say something to make me frightened or worried, my “heart might stand still”.
【小题1】If you are not so happy, you may feel that ________.

For some people, music is no fun at all. About four percent of the population is what scientists call “amusic.” People who are amusic are born without the ability to recognize or reproduce musical notes (音调). Amusic people often cannot tell the difference between two songs. Amusics can only hear the difference between two notes if they are very far apart on the musical scale.
As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their inability to enjoy music set them apart from others. It can be difficult for other people to identify with their condition. In fact, most people cannot begin to grasp what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics intentionally stay away from places where there is music. However, this can result in withdrawal and social isolation. “I used to hate parties,” says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition.
Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complex, and it doesn’t involve defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can’t see certain colors.
Many amusics are happy when their condition is finally diagnosed (诊断). For years, Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. “When people invite me to a concert, I just say, ‘No thanks, I’m amusic,’” says Margaret. “I just wish I had learned to say that when I was seventeen and not seventy.”                                                                                                                       (335 words)
【小题1】Which of the following is true of amusics?

Everyone is at it, even my neighbors. I thought I might be the only person left in the world who hadn’t done an eBay deal. So, I decided to try my hand at online auction (网上拍卖).
Buying for beginners: Sign up on www. ebay. co. uk. Most items（e.g. tables, computers, and books）ready for auction will come with a picture and a short description; others may be marked with “ Buy It Now ” and have a fixed price. You can buy these right away.
If the item is being auctioned, you offer the highest price you are prepared to pay and eBay bids（出价）for you. The bid will be increased little by little until it goes beyond your highest bid, then you are emailed and asked if you would like to bid again. Auctions last up to 10 days and when they finish you get an email telling you whether you have won the item.
How to pay: Sellers decide how they would like to be paid and you need to check this before placing a bid as you might not want to post a check or postal orders. The easiest way is through PayPal, an online payment system that takes the money away from your credit card (信用卡).
Selling made simple: If you plan to sell on eBay, it helps to include a picture of the item. I followed my friends’ advice and put up the items I wanted to sell for a 10-day auction, starting on a Thursday. This way buyers had two weekends to bid.
The big things in life: It’s easy to post a small item, but furniture is a big part of eBay and this has to be collected or sent by delivery men. Check the ways of delivery before you bid.
