I teach online and have been doing so for years .I understand the value of traditional face-to-face course offerings for certain courses and certain subjects. I doubt an online course in chemistry can ever be as effective (有效的) as a face-to-face course held in a lab. Fortunately, I teach writing, and the Internet is an effective place for teaching subjects that call for careful reading and discussion.
It is true that there are things I cannot do in my classes on the Internet. It is also true, however, that there are things I cannot do in my classes held in traditional classrooms. So the question we should ask is: What works better or worse in face-to-face classes rather than in online courses, and vice versa(反之亦然)?
One of the things I value most in my online classes is the necessity for everyone to take part in order to show their presence. In my face-to-face classes, a student can sit quietly and appear to be engaged in(积极参与) the discussion without ever offering a thought or opinion. Online, I consider a student who sits quietly but who does not join in the discussion to be simply not present. Further, students in face-to-face classes who are too shy or who are talked over by quicker and louder voices have the chance to take part in an online discussion.
When I teach online, my students and I can be inside or outside and we can sit wherever and however we want. In Michigan, where a winter storm can make going to campus dangerous or even impossible, the ability to learn in class from the comfort of wherever you live is a big advantage. When the weather is not nice, I often teach while sitting in a local coffee shop. When the weather is nice, I often teach while sitting in my backyard.
I agree that online education is not a “recipe (秘诀)for personal success.” Then again, I’m not sure traditional face-to-face education is such a recipe, either.

When I was young, I dreamed of becoming many things. Sometimes, I wished I was a astronaut going up into space, finding new planets but jumping around in a cool space suit. Other times, I imagined that being a cowboy in the Wild West, wearing stylish cowboy boots. On other occasions, I pretended to being a famous footballer, using my skills score lots of goals for my favourite team. Growing up with siblings also helps, combining our ideas and putting our thought into action. I was even able to create entirely plots in my head, using nothing more than my brain.
Looked back, I realize the imagination is a wonderful thing in your life.
It was the homecoming parade in Rockwall, Texas, and Tyra Winters was riding on top of one of the school's floats. As it slowly made its way down the street, the 17-year-old excitedly_______ at the crowd.
All of a sudden, there was a terrible_______. Looking down. Winters saw a two-year-old_______ on the sidewalk, his frightened mother crying for_______. The child had been sucking on a piece of candy_______ it slid down the back of his mouth, stuck in his_______. There was no coughing. He was_______ having difficulty breathing. No one seemed to_______ how to help.
Except for Winters. A senior with_______ of becoming a surgeon, she had learned________ in school. Knowing that the clock was________, she jumped off the moving float and ran to the child. By the time she got to the child, his________ had turned purple. She grabbed him from the mother. Then she________ him and gave three back pushes. Soon, the boy________ the piece of candy and began breathing again.
Without another word, Winters________ him back to the mother and went back to her float________ before it could leave her behind. It all ________ so fast that the mother never had time to________ the teen. “She didn't need to,” says Winters. “I knew what she was ________. I saw her tears. I saw her face.”
A good thing, because Winters's heroic actions________ the mother speechless. “I don't really have any words,” the mother says. “The words that you would say to anyone who does something for you is 'thank you. ' But that doesn't seem good enough.”

Prevent Viruses From Infecting Your Computer
The number one way to prevent viruses from infecting your computer is to have an anti﹣virus software on your computer, which can detect and block viruses before they have a chance to cause any harm. 1. If it finds any viruses, it can separate them and delete them safely from your computer. Because there are new viruses that are created on an almost daily basis, your virus protection needs to be updated regularly.
2. This way if your computer should ever get hit by a virus, which corrupts some of your system. you will have a back up copy available. 3. This will allow you to restart your computer using an earlier configuration （配置）before you got infected by the virus. This method is not always reliable but it is something that you can try.
An important rule of thumb is do not open attachments in emails from people you do not know. You have no idea what those attachments might contain and no idea who sent them. You should also be careful about opening attachments from people you do know if you are not sure what the attachment is about. 4.
Downloading is a good way to catch a computer virus. It's like opening the door and saying "Come on in! " Yes, if your virus protection is updated, it will hopefully catch the virus. 5. When downloading, make sure the site you are downloading from is reliable with a lot of traffic. Stay away from unreliable sites that have few visitors.
A.Not all viruses act immediately.
B.But then again, it might not.
C.Operating without a firewall is risky anyway.
D.Attachments are a good way for viruses to sneak into your systems.
E.A good anti﹣virus program can scan any program, files, or documents.
F.Another good way is to make backup copies of important documents and files.
G.You can even set a system restore point anywhere from a week or a month earlier.
