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.Which helps to explain why it is difficult to travel in Everglades?

Sam, a dog, was left behind in Colorado while his owners, Mr. And Mrs. Green moved to Southern California. They did not give the dog up. They found him a very nice home before they moved. They would have let Sam accompany them, but they were afraid the dog’s presence would make it difficult for them to rent a house when they reached their destination.
The Green family lived in Colorado for less than a year. Before that, they had lived in the same neighborhood in California to which they returned. So Sam had been there before, but only for a short time when he was young.
Several months after the Greens left Colorado, after they were comfortably settled back in California, they heard a scratch at the door. They couldn’t imagine who might be there. It never occurred to them that it might be Sam, because they were sure he was happily set up with his new family back in Colorado. When they opened the door, the Greens saw a dirty, tired dog with very hurting feet. The animal looked a little bit like Sam, but no one could believe that Sam could have walked 840 miles on his own. The tired dog spent the night under the family car. The next day, when he was more rested, he performed some of his old tricks.

A good memory is a great help in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children, like boys and girls who live abroad with their parents, seem to learn two languages almost as easily as one. In school it is not easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects, too.
A man’s mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way there is much work to be done before we can keep a picture forever in our mind.

Now came great news! It came from a neighboring state, where the family’s only surviving relative lived. It was Sally’s relative — a distant relative by the name of Tilbury Foster, seventy and single. Tilbury now wrote to Sally, saying he should shortly die, and should leave him thirty thousand dollars, cash; not for love, but because money had given him most of his troubles, and he wished to place it where there was good hope that it would continue its evil work. The bequest would be found in his will, and would be officially handed over provided that Sally should be able to prove to the executors (遗嘱执行人).
As soon as Aleck had partially recovered from the strong emotions created by the letter, she sent someone to the relative’s home and subscribed for the local paper.
For the rest of the day Sally made confusion with his books, and Aleck could not keep her mind on her affairs, not even take up a flower-pot or book or a stick of wood without forgetting what she had intended to do with it. For both were dreaming.
“Thirty thousand dollars!”
All day long Aleck was absorbed in planning how to invest it, Sally in planning how to spend it.
There was no romance-reading that night. The children took themselves away early, for their parents were silent, disturbed, and strangely unentertaining. Two pencils had been busy during that hour — note-making; in the way of plans. It was Sally who broke the stillness at last. He said, with excitement, “Ah, it’ll be grand, Aleck! Out of the first thousand we’ll have a horse and a buggy for summer, and a cutter and a skin lap-robe for winter.”
Aleck responded with decision and calmness.
“You can spend a part of it. But the whole of the capital must be put right to work.
“Why, yes. Yes, of course. Have you got it invested yet?”
“No, there’s no hurry about that; I must look around first, and think, er…, I’ve turned it over twice; once in oil and once in wheat.”
“Why, Aleck, it’s splendid! What does it amount to?”
“I think — well, to be on the safe side, about a hundred and eighty thousand clear, though it will probably be more.”
“My! Isn’t it wonderful? Good heaven! Luck has come our way at last, Aleck!”
Then they went up to bed, but they left the candle burning in the sitting room. They did not remember until they were undressed; then Sally was for letting it burn; he said they could afford it, if it was a thousand. But Aleck went down and put it out.
A good job, too; for on her way back she hit on a scheme that would turn the hundred and eighty thousand into half a million before it had had time to get cold.Why would Tilbury like to give all his money to Sally?
| A．Because Sally was Tilbury’s only relative alive. |
| B．Because Tilbury loved Sally and his family deeply. |
| C．Because Tilbury wanted his money to continue its function. |
| D．Because Sally and his wife are good at investing. |
The underlined word “bequest” in Paragraph 1 probably means ___________.
| A．a gift of personal property |
| B．a proof of a person’s identity |
| C．a method of getting money |
| D．a reason for giving money |
What do we know about Sally and his wife after receiving the letter?
| A．They were in deep sorrow and stayed up all night. |
| B．They cared little about the bequest and lived their life as usual. |
| C．They paid a visit to Tilbury to confirm the truth of the letter. |
| D．They had a big ambition to invest the money and make huge profits. |

MOOCs (Massive Open Online Courses) are free, but without tutoring, and are open to anyone, anywhere in the world. The courses are flexible – normally three to five hours of study a week – done at any time, short (5 to 10 weeks) and video-rich. They are also heavily dependent on crowd sourcing: you can discuss a course with fellow students through online forums, discussion boards and peer review. Students don't have to finish the courses, pass assessments or do assignments, but, if they do, they get a certification of participation.
The Open University launched FutureLearn, the UK's answer to US platforms such as Coursera, EdX and Udacity, which have been offering MOOCs from top US universities for the past two years. The response has been incredible, with more than three million people registering worldwide. Meanwhile, in 2012, Edinburgh University became the first non-US institution to join Coursera's partnership, comprising 13 universities. “We already run 50 online master's degrees, so this was a logical expansion,” says Professor Jeff Haywood, Edinburgh's vice-principal. “It's an investment in teaching methods research. How am I going to teach introductory philosophy to 100,000 people? That's what I call educational R&D.” He adds “If you look ahead 10 years, you'd expect all students graduating to have taken some online courses, so you've got to research that. Our MOOCs are no more in competition with our degrees than a lifelong learning course because they don't carry credits.”
Cooperation is key, Haywood stresses. It is far better to offer 20-30 courses in your own areas of expertise (专门技能) and let other institutions do likewise. Professor Mike Sharples, FutureLearn's academic lead, goes further: “We've tied the elements available before into a package of courses offered by leading universities worldwide on a new software platform, with a new way of promoting it and also a new social-learning teaching method. You won't just receive an exam, but be able to discuss and mark each other's assignments.”
Bath University, one of more than 20 universities working with FutureLearn, launches its first course, Inside Cancer, next January, and regards MOOCs as a way of breaking down age barriers. "There's no reason why someone doing GCSEs should not look at our MOOCs and get quite a way through them, or someone at PhD level and beyond," says Professor Bernie Morley, expert for learning and teaching.
MOOCs have these features EXCEPT that ___________.
| A．MOOCs are free of charge for anyone |
| B．MOOCs can be adjusted according to people’s learning pace |
| C．MOOCs provide teachers’ instructions if you have some difficulty |
| D．MOOCs have a platform for learners to share their learning experience |
The response to FutureLearn has been thought to be unbelievable mainly because ___________.
| A．all the courses on the platform are available to anyone in the world |
| B．Edinburgh University became the first non-US institution to join it |
| C．the number of people registering in the platform is beyond expectation |
| D．students can get a certification of participation without passing assessments |
What can be inferred from Professor Bernie Morley in the last paragraph?
| A．People with various learning levels will probably show interest in MOOCs. |
| B．People at PhD level have already known everything about MOOCs. |
| C．Inside Cancer will be the most popular course for someone doing GCSEs. |
| D．MOOCs are not so competitive as lifelong learning courses due to the problems of credits. |
The passage mainly deals with ___________.
| A．the various opinions on FutureLearn |
| B．the advantages of online teaching methods |
| C．the popularity of no-credit courses |
| D．the appearance of a new learning platform |
