MOOCs, an acronym(缩写)for “massive open online courses,” mark an important, possibly revolutionary, development in education. These courses are online, free of charge, and open to anyone in the world who has a laptop and an Internet connection. Moreover, they are mainly offered by elite universities like Standford, Berkeley, Harvard and Columbia.
The courses, like normal college courses, are sequenced(按顺序排好)by difficulty, enabling students to progress from beginners to the advanced. The courses cover not only a broad range of technical subjects such as math and computer science, but also courses in the social sciences and the humanities (人文学科).
Though MOOCs are not offered for credit and degree, many students enroll in the courses for real skills or knowledge which they can put to some practical use. Some students even form online study groups, or in-person groups with students who live nearby.
The format seems superior to the traditional school class. The average quality of the lecturer is much higher, because students do not have to stick with a mediocre(平庸的) lecturer.
Besides, students can scroll back or forward—in short, they can go at their own learning speed, which they cannot do in a live lecture. And, of great importance, they do not have to travel anywhere to attend an online lecture. One can obtain a first-class American college education wherever he or she lives and however little money he or she has.
There is a problem of asking questions of the lecturer in a class of ten thousand students, but some MOOCs have solved it by allowing students to post questions online for a vote, and only the most popular questions are put to the lecturer.
In a knowledge era, lifelong learning is not confined to a traditional classroom. Of course, students enrolling in MOOCs cannot be compared with those who are in traditional universities, but we need to rethink what a “students” is.
Students in MOOCs are very clever, have work experience, and in many cases, have already developed a set of core competences. Moreover, they also offer unique international perspectives that would be the envy of any school classroom.Which of the following statements is NOT true about MOOCs?

The surprising experiment I am about to describe proves that air is all aroud you and that it proves down upon you．Air pressure is a wonderful force．When you swim underwater, you can feel water push down your body．The air all around you does the same．However, your body is so used to it that you do not notice this ．The pressure is caused by a layer of air called the atmosphere．This layer surrounds the Earth , extending to about five kilometers above the Earth’s surface．
The following experiment is an easy one that you can do at home．But make sure that you are supervised , because you will need to use matches．Now for the experiment！
What you need
·A hard-boiled egg without the shell
·A bottle with a neck slightly smaller than the egg
·A piece of paper
·A match
Metheod
1) Check that the egg will sit firmly on the neck of the bottle．
2) Tear the paper into strips and put the strips into the bottle．
3) Light the paper by dropping a burning match into the bottle．
4) Quickly sit the egg on the neck of the bottle．
Result
Astonishingly,the egg will be sucked into the bottle．Your friends will be amazed when you show them the experiment．But be careful when you handle matches．
Why it happened
As the paper burns,it needs oxyen and uses up the oxygen(air) in the bottle．The egg acts as a seal in the neck of the bottle,so no more air can get inside ．This reduces the air pressure inside the bottle．The air pressure must equalize,so more air from outside must enter the bottle．The outside air pressure against the egg and then the egg is pushed into the bottle!The proves that air is all around and that it is pressing down on it．
53．When you do the experiment, why need you a person beside you?
A．You couldn’t place the egg on the bottle by yourself．
B．The egg needs to be shelled．
C．You need to use matches．
D．The bottle can’t sit firmly on the desk．
54．The purpose of doing this experiment is to prove ______．
A．air pressure is a wonderful force
B．water can push down your body when you swim underwater
C．the air pressure is not equalized around us
D．the earth is surrounded by a layer of air called the atmosphere
55．How did the egg put into the bottle？
A．The oxygen inside the bottle suckde the egg in．
B．It became solt without the shell．
C．The neck of the bottle was wide enough．
D．The outside air pressure forced it into the bottle．
56．The passage is ______．
A．an experiment report B．a scientific story
C．a research report D．an interesting novel
If you know exactly what you want, the best way to get a job is to get specialized training. A recent report shows that companies like graduates in such fields as business and health care who can go to work immediately with very little on-the-job training.
That’s especially true of booming fields that are challenging for workers. At Cornell's School of Hotel Administration, for example, bachelor's degree graduates get an average of four or five job offers with salaries ranging from the high teens to the low 20s and plenty of chances for rapid advancement. Large companies especially like a background of formal education coupled with work experience. But in the long run, too much specialization does not pay off. Business, which has been flooded with MBAs, no longer considers the degree an automatic stamp of approval. The MBA may open doors and command a higher salary initially, but the impact of a degree washes out after five years.
As further evidence of the erosion of corporate faith in specialized degrees, Michigan State’s Scheetz cites a pattern in corporate hiring practices. Although companies tend to take on specialists as new hires, they often seek out generalists for middle and upper-level management. This sounds like a formal statement that you approve of the liberal-arts(文科) graduate. Time and again labor-market analysts mention a need for talents that liberal-arts majors are assumed to have: writing and communication skills, organizational skills, open-mindedness and adaptability, and the ability to analyze and solve problems. David Birch, manager of the Boston Red Sox, says that he does not hire anybody with an MBA or an engineering degree. “I hire only liberal-arts people because they have a less-than-canned way of doing things,” says Birch.
For a liberal – arts degree, students focus on some basic courses that include literature history, mathematics, economics, science, human behavior and a computer course or two. With these useful and important courses, you can feel free to specialize, “A liberal-arts degree coupled with an MBA or some other technical training is a very good combination in the marketplace,” says Scheetz.

A．special training in special fields

A．they will follow others’ ways of solving problems
B．they can do better in bundling changing situations
C．they are well trained in a variety of specialized fields
D．they have attended special programs in management

While I was in 9 th grade, I built a circuit (电路装置) for the traffic system of our city. After getting the first prize. I got this valuable advice from my father; “Do whatever interests you, and don’t let the work challenge you, make sure you are challenging that work.”
I have always preferred the projects which are challenging and related to real life problems. I clearly remember building a shipping program several years ago. I divided the whole project into several small sections. When I understood it clearly, used my brainstorming skill on it, and gave some basic ideas. Then I asked my professor for help before jumping into coding (编码). At first, I did not know how to ask questions correctly and always asked the question “How do I do it?” As I kept working and discussed with my professor, I became more comfortable and those “how ”questions soon turned into “what if I do this and that” types of questions.
It took me four days to write the code. The desire to solve the problem kept me sleepless all nights brainstorming in even greater details. Every time I saw my program running smoothly, I exploded with joy. I still remember the last day of my work. I was getting some problem and didn’t know what to do. At that moment, a man came in to clean. He has headphones, and he was dancing while cleaning the room. Seeing this, I burst out laughing. That moment calmed me. I regained energy and interest and started to work again, and soon I fixed the problem.
My success in the project proved that breaking up a large problem into small parts could help find a possible solution. Discussing the problem with others was also very beneficial. Now I have gained the confidence to attempt any kind of project.
