As is followed by a subject and verb. For example, "She's a good student, as her brother was before her." However, in spoken English, like is often used instead of as. "She's a good student, like her brother was before her." As is used with a preposition, such as, "As in the 1960's, the population explosion will cause some problems." We can use as in certain expressions, such as "as you know", "as you requested", "as we agreed". We also use as…..as to give comparisons. For example, "He's as clever as his sister." 'Like' and 'as' are often confused in English. They can both be used to talk about how things are similar. Like is followed by a noun or pronoun. For example, "I'm like my sister", or "Like my sister, I have brown eyes." When we use "like" in this way, we can describe physical similarity as well as similarity of character. "I'm like my sister. We both have dark hair." "I'm just like my sister. I hate it when people are

Hi - you can use 'as' to compare, for example I am as tall as you are You can use 'like' to see a similarity Am I tall like you? You can use them both to mean 'in the way that' He will be a good football player as his father is. She will enjoy horse riding like her mother does. You can also 'like' something, when used as a verb. I like being as tall you are.

It's very clear, thanks :)
