How can i express some personal attitude in english? If i take someone as a friend, deep in heart i have a friendly attitude towards him,and if i dislike someone i may have negative attitude towards that person.But i dont know how to express such attitude in proper way. if i say ' i have good|bad attitude towards him', it sounds far from native tone. so what is the idiomatic way to express the feeling??
This sort of direct statement about one's feelings toward another person isn't particularly common in American English, but there are equivalent statements that are commonly used.
First, the phrases "bad attitude" and "good attitude" have specific meanings that have very little to do with what you're looking for. Instead they describe a person's outlook in life, or their ability to work with a group. If I say, "John has a bad attitude," I mean that John is not being helpful and that he is a negative person (in the context of whatever we're working on together.) If I say, "I have a bad attitude toward John," then I am saying that I am behaving poorly toward him and treating him unfairly. The fault is mine entirely.
The simplest way to make the sort of statement you seem to want is to state your affection for them with like/to be fond of/love/hate. All three of these involve some ambiguity, since they can be used to express increasingly positive feelings toward a person or thing in general but also to express increasing levels of romantic interest toward someone. Like is generally safest, but it's also boring.
I like John. or I dislike John.
Usually you would add to this a reason why you like or dislike him, particularly if there is a chance that you might be romantically interested in the person you've said that you like.
I like John; he's a hard worker.
I like John; his eyes are beautiful.
You can also use "to be fond of" for this sentiment, though it is a little old fashioned. It also tends to be directed toward the personal qualities of the object rather than toward his or her actions. You're not fond of someone because they are good at fixing computers, you're fond of them because they're kind or generous.
In my experience, the negative version of this is used as a softer version of disliking someone. I am not fond of John. is gentler than I dislike John. To be clear, this is my personal observation; I don't know how broadly applicable it is.
You would reserve love/hate for something that you felt very strongly positive or negative feelings toward. Love, when applied to people, usually means romantic interest, but not always. If I were talking about my favorite student, I might say, I love John, he's such a pleasure to teach. I would definitely supply a reason to express that my love is platonic and not romantic in this situation.
Hate is a very strong negative verb. It's fine to use on objects (I hate the taste of cabbage!) but be careful when applying it to people.
Finally, rather than describing our feelings about one another, we often just state our relationships and the feelings associated with them are assumed. John is my friend. John is my best friend. John is my boyfriend.
There are a hundred other ways to say this sort of thing that are situational, but without more information it's hard to say what would fit your needs.
