Finding Topic Sentence หรือ Finding Main Idea คือการหาประโยคใจความสำคัญในสิ่งที่อ่าน

How to find the main idea  หาประโยคใจความสำคัญได้อย่างไร
main idea How Can I Locate the Main Idea?

ขั้นแรกต้องหาหัวเรื่องหลักก่อน (topic)

Once you can find the topic, you are ready to find the main idea. The main idea is the point of the paragraph. It is the most important thought about the topic.

To figure out the main idea, ask yourself this question: What is being said about the person, thing, or idea (the topic)?

The author can locate the main idea in different places within a paragraph. The main idea is usually a sentence, and it is usually the first sentence. The writer then uses the rest of the paragraph to support the main idea.

 ลองฝึกหาหัวเรื่องจากเนื้อหาที่อ่านก่อนแล้วหาใจความสำคัญต่อ

Let's use the paragraph below as an example. First find the topic, then look for the main idea.

  Task 1                     

  Summer is a wonderful time to spend at West Beach. It is a beach with light-

  colored, soft sand. The coastline goes on for a long way and many people enjoy walking

  along it. Children like to play in the surf and walk along the rocks that are visible at

  low tide. This is a fun beach for people of all ages.

In this paragraph:   

the topic is West Beach

the main idea (what the writer is saying about the topic) is that summer is a wonderful time at West Beach

Here is another example:

             The movie Apollo 13 was a blockbuster for the summer of 1995.

             It is an exciting story about space exploration. In the movie, the astronauts

             get in trouble while they are trying to return to Earth. People in the audience

             are on the edge of their seats waiting to see what happens. What makes it even

             more exciting is that it is a true story.

In this paragraph: 

the topic is the movie Apollo 13

the main idea is in the first sentence: Apollo 13 was a blockbuster for the summer of 1995

While the main idea is usually in the first sentence, the next most common placement is in the last sentence of a paragraph. The author gives supporting information first and then makes the point in the last sentence.

 ประโยคใจความสำคัญมักจะอยู่ในประโยคแรกแต่บางครั้งสามารถพบในประโยคสุดท้าย  โดยผู้แต่งนำประโยครายละเอียดมาไว้แรกๆก่อน 

Here's a paragraph we can use as an example. Try to locate the topic and the main idea.

ศึกษาตัวอย่างต่อไปนี้                      

                       Most teenagers and young adults do not know what they want to do for the rest

                       of their lives. It is a big decision. There are a number of things you can do to narrow

                       the choices. For example you can take an interest test, do some research on your own

                       about a career, try volunteer work in the field in which you are interested, or "job-shadow",

                       in which you spend a day with a person who is working in a field that interests you. These

                       are just a few helpful ideas as you begin to choose a career.

      In this paragraph:

the topic is jobs or career choices

the main idea is a few ideas to help the reader choose a career 

Finally, an author might put the main idea in the middle of a paragraph. The author will spend a few sentences introducing the topic, present the main idea, then spend the rest of the paragraph supporting it. This can make the main idea more difficult to find.

See if you can find the topic and main idea in the paragraph below.

                         The United States seems to be in love with the idea of going out to eat.

                        Because of this, a real variety of restaurants has come about specializing

                        in all kinds of foods. McDonald's is the king of a subgroup of restaurants

                        called fast-food restaurants. Chances are, no matter where you live, there

                        is a McDonald's restaurant near you. There are even McDonald's in the

                        Soviet Union. Now McDonald's is trying something new. It is called McDonald's

                        Express and there is a test site in Peabody, Massachusetts. It is part of a Mobil

                        gas station. This allows you to fill up with gas and fill up on food at the same time.

                        What will they think of next?

     In this paragraph:

the topic is McDonald's

the main idea is in the middle of the paragraph, in the third sentence: McDonald's is the king of fast food

Task 2: Finding Main Ideas

The Latest Craze in Blogging - Video Blogging

P.1 Recently, blogs have gained much popularity in many online communities because people have the ability to hide their identity and write about subjects that they relate to, and sometimes bloggers feel strongly towards a certain story or issue. Vblogging has become a recent We then look towards vblogging, which is changing the way we look at blogging and bloggers.

Main Ideablogs have gained much popularity in many online communities

P.2 Vblogging allows users and readers to see the face of the blogger, while he talks away to his readers. Some bloggers may not be comfortable talking to a camera, and may want to just continue to write on their blogs without showing any interest in what vblogging can actually do for their and that their facial expressions are on show to the whole world, but others might jump at the chance. Some of these such people will stick to traditional blogging in the sense of writing posts to their blog and ignore the aspects of video blogging.

P.3 If you're a person who is shy in-front of the camera, then vblogging (video blogging) probably isn't going to be good for you, as the whole world could potentially view your videos online. If you are having problems and trying to find the time to post two or three times to your blog each day, then you are probably better to not produce any video posts to your blog, as you should publish a regular traditional written post each day too. Many internet users love video blogs as they share so much incite than a post could do, yet many internet users and blog readers like to read and comment on the more traditional blog posts written by their favourite bloggers. So, unless your blog is downright crap you probably should continue doing what you are as your readership will continue to read your blog and other traditional blogs in your niche.

P.4 If you've made the decision that vblogging is for you and that you're going to start a vblog, then you will need to pay attention to a few important points. The most important is that your face will be viewed by millions of people throughout the world who tune into see your vblog. Your video and image, once loaded will stay on the internet for quite a long time; therefore, if you don't want to appear all over the internet then I would suggest that vblogging is just not for you. But, you should keep at your traditional blogging of posting daily, as subscribers will want to stay tuned so that they don't miss any important stuff that you have to say or comment on.

P.5 If you're serious about using video posts on your blog then you should look into doing many different things. You will need to keep your video posts short, engaging to the reader and humuorus at the same time. You will need structure for what you are going to say, just like you would when you write a blog post, and you will need to follow the plan you have so you're not considered a 'rambler vblogger'. Having weekly themes on your blog can help people in making the decision to come to your blog to watch your weekly video - this will also create an increased amount of traffic to the other posts on your site, as many people will view your other posts after they've watched your weekly video.

P.6 Vblogging is similar to traditional blogging in a couple of ways. A topic that you feel comfortable about is best for your to actually talk about in your videos, you will feel more comfortable and confident talking about something you have at least a little knowledge about and an area that interest you somewhat - you will need increased commitment to a video blog, as many video posts take a lot more time and effort than writing a 1,000 word post. You could choose to hire an actor/actors to produce your video post for you, but this may become expensive and most probably isn't a representation of you, the actors could read the scripts you provided them, but they would end up being the 'front line face' for your blog - doing this can protect your identity, but it can also have negative impacts on people recognising you later as a video blogger (vblogger).

Main IdeaVblogging is similar to traditional blogging in a couple of ways

P.7 Setting up your very own vblog really isn't too difficult, all you need is a video camera, some editing software to remove the parts of the recording that aren't needed and the ability/time to upload and configure the video to your blog. Some people put up video posts onto their blogs as much as twice per day, so, you will need to look at what type of schedule that you're looking at and think about whether you want to vblog or not. Now, many other bloggers, who have traditional blogs do tend to publish a video post once a week or once every two weeks, so if you want to try this on your traditional blog then it could be a good start.

Main IdeaSetting up your very own vblog really isn't too difficult

P. 8 If you have a number of blogs that you post to, then you might not have the time to setup a vblog and post videos to it daily - this is ok, as most readers will like the enjoyment and anticipation of when the next video post is going to be published. Vblogging is very exciting and fun, as it lets you become 'face to face' and actually speak to the readers of your blog, doing so increases the readability of your blog and the quality that your blog is accepted in.

Main IdeaVblogging is very exciting and fun

P. 9 VBloggers who have vblogs are gaining a huge following online and are staring in their own shows, some are talking about quite controversial topics too and are thus creating a substantial readership base and following. Vblogs include not only the video blogger, but other people (including their family and friends) that they invite to star in their videos. Some video blog posts even include work colleagues or mentors to help the video blogger achieve credibility in their topic area. Internet users who search across the internet are generally wanting to find answers to certain questions, as well as enjoy a giggle or two whilst doing it; video blogging takes this to the next stage and looks at blogging as even more of a personal view of a part of the world's online community.
