Read the following text on Skimming and scanningWhen you’re reading you don’t have to read everything with the same amount of care and attention. Sometimes you need to be able to read a text very quickly.For example, to look up the word ‘valuable’ in the dictionary you wouldn’t start at the letter A and read every word. The most efficient way is to turn to the letter V and then find the words beginning with VA-. This is called scanning through the dictionary. Scanning is one type of fast reading.Skimming is another type of fast reading. You might use skimming to look through a text quickly to get the gist (the general idea). So, if you want to know what’s going on in the news, you might skim through a newspaper or a news website. You wouldn’t have much detail but you would find out the main points. Skimming and scanning are both quick reading techniques but they have different purposes.How is skimming different to scanning?
