As the MOOC craze continues to explode, anyone interested in taking an online course faces a tricky question: Which course to take? Here are five aspects that you should consider before you start.
(1)What is your learning style?
Many MOOCs are video-based. Other courses use presentation formats. Some also require participation in group work. If you want to stay motivated during your course, think about how you enjoy learning.
Are you a visual learner, preferring to use images to understand a topic? If so, a video-based course will work well for you. If you are a verbal learner who gains new information by speaking and writing, try a text-based course with lots of note-taking. Social learners, meanwhile, will thrive in forum discussions and project-based assessment.
(2)Are you ready to become a full-time student?
Be realistic about the time that you can commit to your online studies. Participating in an online course can take as much time and commitment as a class-based program. Check the course requirements and make a plan around your current schedule.
(3) Does the course really meet your needs?
Whether you are interested in a professional qualification or want to take a personal development course like yoga, there is a MOOC for you. It's easy to get caught up in the excitement of taking lots of free courses in everything that you ever wanted to learn. Before you start a course, think about the end goal. Is the course aimed at beginners or advanced learners? Why do you need this qualification?
(4) Do you need a support group?
Some people learn best from seeing how others approach the problem. If you are such as learner, you will need to supplement your online lessons with an in-person support group.
(5) What kind of certification will you get?
Take time to find out what kind of certification is available upon completion of the course, and how you can prove your learning to others - for example, certificates, transcripts or digital badges.
1. What kind of MOOC's does the author recommend to verbal learners?
A. A video-based course.

A team of engineers atHarvardUniversity in trying to create the first robotic fly. Designed to do what a fly does naturally, the tiny is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.
"The added difficulty with a project like this is that actually none of its components is off the shelf and so we have to develop them all on our own’ said Robert Wood, a Harvard engineering professor.
They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves the wings hasa number of interdependencies (相互依赖）on the individual components, each of which individually has to perform well, but then has to be matched well to everything it d connected to,” said Wood.
While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gathering work at rescue sites，in farmers’ fields or on the battlefield. "Basically it should be able to take off, land and fly around，” he said.
Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could have much broader applications.“You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animal，but using these robots instead” he said. "So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day-to-day basis.”
4. What is the typical characteristic of the robotic fly?
A. It's automatic.
B.It's very small.
C. It's controllable.
D. It's quite powerful.
5. We can infer from the passage that the robotic flyer can____ .
A. act as a spy plane
B. help do farm work
C.fly at a very high speed
D. answer many scientific questions
6. What is Wood's idea about the robotic fly according to the last paragraph?
A. It is highly questionable.
B. It has wide practical applications.
C. It gives scientists interest in flying machines.
D. It points to a new direction in studying biology.
7. What can be the best title for the passage?
A. Harvand's Study in the Field of Insects.
B. A Breakthrough in Engineering Science
C. An Interesting Invention一Robotic Fly
D. Robotic Fly一a Copy of Real Life Insect
C
Pigeons inLondonhave a bad reputation. Some people call them flying rats. And many blame them for causing pollution with their droppings. But now the birds are being used to fight another kind of pollution in this city of 8.5 million.
“The problem for air pollution is that it’s been largely ignored as an issue for a long time,” says Andrea Lee, who works for the London-based environmental organization Client Earth. “People don’t realize how bad it is, and how it actually affects their health.”London’s poor air quality is linked to nearly 10,000 early deaths a year. Lee says, citing(引用)a report released by the city manager last year. If people were better informed about the pollution they’ re breathing, she says, they could pressure the government to do something about it.
Nearby, on a windy hill inLondon’s Regent’s Park, an experiment is underway that could help—the first week of flights by the Pigeon Air Patrol. It all began when Pierre Duquesnoy, the director for DigitasLBi, a marketing firm, won a London Design Festival contest last year to show how a world problem could be solved using Twitter. Duquesnoy, fromFrance, chose the problem of air pollution.
“Basically, I realized how important the problem was,” he says. “But also I realized that most of the people around me didn’t know anything about it.” Duquesnoy says he wants to better measure pollution, while at the same time making the results accessible to the public through Twitter.
“So”, he wondered, “how could we go across the city quickly collecting as much data as possible?” Drones
were his first thought. But it’s illegal to fly them overLondon. “But pigeons can fly aboveLondon, right?” he says. “They live—actually, they are Londoners as well. So, yeah, I thought about using pigeons equipped with mobile apps. And we can use not just street pigeons, but racing pigeons, because they fly pretty quickly and pretty low.”
So it might be time for Londoners to have more respect for their pigeons. The birds may just be helping to improve the quality of the city’s air.
8. What can we infer aboutLondon’s air quality from Paragraph 2?
A. Londoners are very satisfied with it.
B. The government is trying to improve it.
C Londoners should pay more attention to it.
D. The government has done a lot to improve it.
9. Duquesnoy attended the London Design Festival to _________.
A. entertain Londoners.
B. solve a world problem.
C. design a product for sale.
D. protect animals like pigeons.
10. Why did Duquesnoy give up using drones to fly acrossLondon?
A. Because they are too expensive.
B. Because they fly too quickly.
C. Because they are forbidden.
D. Because they fly too high.
11. Which can be the best title for the text?
A. Clean air inLondon.
B. London’s dirty secret.
C. London’s new pollution fighter.
D. Causes of air pollution inLondon.
D
Japan is known to have higher than average rates of stomach cancer. Recently, the town of Kaneyama in Yamagata Prefecture decided to get its 6, 000 residents (居民) tested.
However, the frozen urine samples (尿样) are not tested in conventional ways. Instead, Professor Masao Miyashita and his team are using them in a trial to determine if specially trained cancer-sniffing dogs can accurately detect the disease. Though the study is still in its early stages, Miyashita is thrilled with the results. He said, “In our research so far, cancer detection dogs have been able to find signs of cancer with an accuracy of nearly 100 percent.”
Researchers have known about the animals’ superior sensory skills for decades. However, their ability to detect cancer in humans came to light in 1989, after a dog sniffed out early-stage malignant melanoma (恶性黑色素瘤) on a patient’s leg in London. Since then, scientists from many countries have conducted studies to test dogs’
great skill at identifying cancer chemicals.
While most dogs can be trained for the task researchers say the best candidates are dogs that are precise, quiet, and perhaps even a little shy. The training process is similar to how dogs are taught to learn any trick — by rewarding them with treats! However, it takes much longer because the dogs have to learn to separate the “cancer scent (气味)”from the thousands of organic compounds (有机化合物) in the human body. Researchers begin by exposing the dogs to urine samples from people with cancer, people with other diseases, and patients with no health issues, Once the dogs are able to accurately identify cancer, they are further trained to detect particular kinds of cancer.
Successful as they may be, experts think dogs are unlikely to replace conventional tests. For one, it takes about seven years and costs as much as $45,000 to train a single dog. Klaus Hackner, a researcher and physician who studies dogs detecting cancer in breath samples at Krems University Hospital in Austria, is also not convinced dogs can be relied upon alone. Patients, therefore, have to receive further tests to confirm if they have the disease.
12. What do we know about the cancer-sniffing dogs mentioned in Paragraph 2?
A. They have done a great job.
B. They are trained in a special way.
C. They can easily learn to distinguish cancer.
D. They can be seen in many Japanese hospitals.
13. What does the author intend to do in Paragraph 3?
A. Offer readers some advice.
B. Add some background information.
C. Summarize the previous paragraphs.
D. Introduce a new topic for discussion.
14. What kind of dog is suitable for the cancer-sniffing job?
A. Smart and brave.
B. Active and faithful.
C. Strong and patient.
D. Careful and peaceful.
15. What is Klaus Hackner’s opinion on cancer-sniffing dogs?
A. They should work as a team.
B. They need to receive more training.
C. They can replace doctors in detecting cancer.
D. They should be used together with traditional tests.
