The huge Florida wetland known as the Everglades is a slow-moving river 80 kilometres wide but only a few centimeters deep. People call the Everglades a “river of grass” because sawgrass covers most of it. Sawgrass is not really grass. It is a plant that has leaves edged with tiny sharp teeth that can easily cut through clothes—and skin!
Travel in the Everglades is difficult. You cannot walk through shallow water because the sawgrass will cut you. The water is too shallow for regular boats. So, we use an airboat. An airboat is a flat, open boat. Like an airplane, it has a big propeller to move it. The propeller is fixed on the rear of the boat. It makes a tremendous noise, but it does the job. The boat skims along the water’s surface. Although we can still get lost in an airboat, at least we are above the alligators(短吻鳄).
While hundreds of different kinds of animals live in the Everglades, the most famous is surely the alligator. Once endangered, alligators are now protected within Everglades National Park. Visitors are likely to see them both on land and in water.
For a long time, dangers have threatened the Everglades. Around 1900, some people felt this precious wetland should be drained (排干). They said it was just a big swamp and not good for anything. In the 1920s, there was a land boom in Florida. People wanted to build homes everywhere, including in the Everglades. They built canals, levees (防洪堤) , and other water systems that stopped the rivers flowing into the Everglades. Factories were built near rivers that flowed into the wetland. These factories dumped poisonous waste that damaged the Everglades ecosystem.
? People are now working to preserve the Everglades National Park for the future. Right now, one big problem is the paperbark tree. This tree is an invader from Australia.
Paperbark trees soak up a lot of water. In the early 1900s, people brought them to Florida because they thought they would help drain the Everglades. However, the invaders adapted too well. Paperbark trees have taken over hundreds of thousands of acres of the Everglades and killed other trees. Scientists are cutting down these invaders or spraying them with herbicides (除草剂) to kill them. ?

The flying fox is not a fox at all. It is an extra large bat that has got a fox’s head, and that feeds on fruit. Like all bats, flying foxes hang themselves by their toes (趾) when at rest, and travel in great crowds when out flying. A group will live in one place for years. Sometimes several hundreds of them occupy a single tree. As they return to the tree towards sunrise, they quarrel among themselves and fight for the best places until long after daylight.
Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her chest wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls to the ground. Then the older ones fly down and try to pick it up. If they fail to do so, it will die. Often hundreds of baby bats can be found lying on the ground at the foot of the tree.

At exactly eleven Sir Percival knocked and entered, with anxiety and worry in every line of his face. This meeting would decide his future life，and he obviously knew it.
"You may wonder, Sir Percival,”said Laura calmly, “if I am going to ask to be released (免除）from my promise to many you. I am not going to ask this. I respect my father's wishes too much.”
His face relaxed a little, but one of his feet kept beating the carpet.
"No, if we are going to withdraw. (退出）from our planned marriage, it will be because of your wish, not mine.
“Mine?” he said in great surprise. “What reason could I have for withdrawing?^’
"A reason that is very hard to tell you," she answered. "There is a change in me.”
His face went so pale that even his lips lost their color. He turned his head to one side.
"What change?" he asked, trying to appear calm.
“When the promise was made two years ago,” she said, ⁴⁴ my love did not belong to anyone. Will you forgive me, Sir Percival, if I tell you that it now belongs to another person?”

Though he wore his whiskers (颊须) only four years, today we can hardly think of Abraham Lincoln without them. He often talked about the little girl in Westfield, New York, who suggested in a letter that he grow the famous whiskers. And he would add, “Sometimes a small thing can change our lives!”
Grace Bedell sat in her room looking at a picture of Lincoln. Her little lamp threw shadows on the picture. A frame (框) of small shadows lay around the thin face and covered the hollow cheeks (面颊). “Whiskers!” she thought.
“How nice!” she said to herself. “There will be more people to elect him President if he lets his whiskers grow. Somebody ought to tell him.” She reached for a pen and began to write the letter.
On February 16 of the following year a special train carried the newly elected President Lincoln to the White House. The train stopped briefly at a station near Grace’s town. At the station Lincoln was speaking to a large crowd, among whom were the Bedell family.
Lincoln continued his speech, “I have a little friend in this place,” he said. “That little lady told me how to improve my appearance, and I want to thank her. If she is present, I would like to speak to her. Her name is Grace Bedell.”
Grace’s father led her forward to Lincoln. She looked and laughed happily, for up there on his face were the whiskers.
If you visit Springfield, Illinois, today you will see the house in which Abraham Lincoln used to live. On the wall of a room hangs a piece of paper covered with a child’s handwriting: “Dear sir...”

Lots of people have hobbies. Some people collect old coins or foreign stamps; some do needlework; others spend most of their spare time on a particular sport.
A lot of people enjoy reading. But reading tastes differ widely. Some people only read newspapers or comics, some like reading novels, while others prefer books on astronomy, wildlife, or technological discoveries.
If I happen to be interested in horses or precious stones, I cannot expect everyone else to share my enthusiasm. If I watch all the sports programs on TV with great pleasure, I must put up with the fact that other people find sports boring.
Is there nothing that interests us all? Is there nothing that concerns everyone—no matter who they are or where they live in the world? Yes, dear Sophie, there are questions that certainly should interest everyone. They are precisely the questions this course is about.
What is the most important thing in life? If we ask someone living on the edge of starvation, the answer is food. If we ask someone dying of cold, the answer is warmth. If we put the same question to someone who feels lonely and isolated, the answer will probably be the company of other people.
But when these basic needs have been satisfied—will there still be something that everybody needs? Philosophers think so. They believe that man cannot live by bread alone. Of course everyone needs food. And everyone needs love and care. But there is something else—apart from that—which everyone needs, and that is to figure out who we are and why we are here.
Being interested in why we are here is not a “casual” interest like collecting stamps. People who ask such questions are taking part in a debate that has gone on as long as man has lived on this planet. How the universe, the earth, and life came into being is a bigger and more important question than who won the most gold medals in the last Olympics.

The third common goal is to do work that we enjoy, to do it well, and to be well paid for it. You want to be able to get and keep the job you want, to get paid more and promoted (晋升) faster. You want to earn the very most that is possible for you at each stage of your career, whatever you do.
The fourth goal we all have in common is to achieve financial independence. You want to reach the point in life where you have enough money so that you never have any financial worries. You want to be completely free of them. You want to be able to order dinner in a restaurant without referring to the price listing to determine what you want to eat.

Health experts are calling for action to expand cancer care and control in the developing world. A medical research paper says cancer was once thought of as a problem mostly in the developed world. But now cancer is a leading cause of death and disability in poor countries as well. Experts from Harvard University and other organizations urge the international community to fight cancer aggressively, saying it should be fought in the way HIV/AIDS has been fought in Africa.
Cancer kills more than 7.5 million people a year worldwide. Almost two-thirds are in low-income and middle-income countries.
They discover cancer dills more people in developing countries than AIDS, tuberculosis (肺结核) and malaria (疟疾) combined. But the world spends only 5% of its cancer resources in those countries.
Felicia Knaul from Harvard Medical School was one of the authors of the paper. She was in Mexico when she was found to have breast cancer. She received treatment there and her experience showed her the sharp difference between the rich and the poor in treating breast cancer.
Felicia Knaul says, “And we are seeing how this is attacking young women. It’s the number two cause of death in Mexico for women thirty to fifty-four. All over the developing world, it’s the number one cancer-related death among young women. I think we have to again say that there is much more we could do about it than we are doing about it.”
Professor Knalul met community health workers during her work in developing countries. They were an important part of efforts to reduce deaths from the cancer. They were able to persuade people to get tested to prevent the illness. The experts say cancer care does not have to be costly. For example, patients can be treated with lower-cost drugs.

Some people think that as more and more people have televisions in their homes, fewer and fewer people will buy books and newspapers. Why read an article in the newspaper, when the TV news can bring you the information in a few minutes and with pictures? Why read the life story of a famous man, when a short television program can tell you all that you want to know?
Television has not killed reading, however. Today, newspapers sell in very large numbers. And books of every kind are sold more than ever before. Books are still a cheap way to get information and enjoyment. Although some books with hard covers are expensive, many books are printed today as paperbooks (平装本), which are quite cheap. A paperback collection of short stories, for example, is always cheaper than an evening at the cinema or the theater, and you can keep a book for ever and read it many times.
Books are a wonderful provider of knowledge and pleasure and some types of books should be in every home. Every home should have a good dictionary. A good encyclopedia (百科全书), though expensive, is useful, too, because you can find information on any subject. Besides, you can have such books as history books., science textbook, cookbooks, and collections of stories and poems. Then from time to time you can take a book of poems off your shelves and read the thoughts and feelings of your favorite poets.

1.
It can be inferred from the passage that ________.
1. A.
  TV programs are a chief provider of knowledge
2. B.
  cinemas are the best choice in getting information

It takes years of school to develop math skills, but learning about numbers starts earlier than you might think. Now according to a new study, at three months, babies have already started acquiring a concept (概念) of “how much”.
Previous research had suggested that very young babies can tell when the number of objects (物体) in a group has changed. But the babies in these studies were simply reacting generally to the fact that something had changed, they suspected.
Researchers of Harvard University studied 36 babies, all three months old. During the tests, each baby wore a hat with sensors (传感器). The babies watched a series of images on a computer screen. They showed the same object, such as a cartoon character. For a while, the number of the objects in the pictures didn’t change. Then the images began to display a different object, or a different number of one of the objects the babies had previously looked at. As soon as something changed, the babies’ brains responded with a specific pattern of electrical signals, which would be recorded by sensors.
By analyzing these signals, the researchers discovered that one part of the brain (near the top on the left side) responded when the object in the image changed. A different part of the brain (lower and on the right side) responded when the number of objects in the image changed. This was not the area of the brain that is involved in attention. That suggests that the babies’ brains are doing more than just reacting to a change in what they’re seeing – they actually seem to be able to tell number changes from other types of changes.
Numbers and amounts are important concepts in our lives. Even though babies are years away from adding, subtracting (减), multiplying, and dividing, their brains seem to be preparing for a time when they finally will.

1.
Why were hats with sensors used in the study?
1. A.
  To record the images on the computer screen.
2. B.
  To remind babies of the changes of numbers.
