you look busy 和 you seem busy 的差別在哪裡？

 

Well, the same when the person is in front of you. It's different when you don't see the person. Text message for example, you seem busy is ok. But you look busy is not because you can't see the other person.

fast和quick，quickly的區別

 一、詞性上面的區別：

fast既是形容詞，也是副詞。quick是形容詞，它的副詞形式是quickly。

二、fast和quick，quickly都翻譯成「快速」，但是它們強調的地方是完全不一樣的。

1）fast表示物體的運動速度很快，強調的是「速度」。比如：一輛汽車在快速行駛；一個人在快速奔跑。在此時，我們不能使用quick來表達。

例如：It is a fast train. 它是一輛速度很快的火車。（強調的是「速度快」）

You walk very fast. 你走的很快。 （強調的是「速度快」）

She loves fast cars. 她喜歡時速很快的車。（強調的是「速度快」）

(Not: She loves quick cars. )

2）quick，quickly表示動作需要在很短的時間內，甚至是比計劃時間更短的時間內，快速完成。也就是說，quick強調的是「時間」，因為時間來不及了，所以動作要以「比正常快的速度」來完成（有一種被催促的感覺在裡面）。

例如：We need to have a quick chat before themeeting . 在開會之前，我們需要抓

緊時間聊一下。（強調的是「時間緊迫」）

We just need a quick answer . （強調的是「短時間內給出回答」）

(Not: We just need a fast answer.)

We should do it as quickly as possible. （強調的是以「儘可能短的時間」快

速完成。）

“What do you do?” or “What is your job?”

 When someone asks you “What do you do?“, they’re asking about your job. In English, people don’t actually say “What is your job?“. Instead they say “What do you do?“ and the correct response is “I’m a/an + a job title”.

Examples:

• I’m an English teacher.
• I’m a dentist.
• I’m a lawyer.

“What is your job?“ is still used in English textbooks, but in real life native English speakers almost never say that. They will mostly say:

• What do you do?
• What do you do for a living?
• What do you do exactly?

What's the difference between “have you seen?” and “have you ever seen?”

 Ever means 'at any time'.

So,

“Have you seen?” is said when you are asking someone if they have seen a particular person or thing in a specified short period of time maybe this hour or this day.

While, “have you ever seen?” is spoken when you are asking someone if they have seen a particular person or thing at any time maybe even once in their whole life.

For example:

• Have you seen Claire? I thought she was waiting for me at the bus stop.

• Have you ever seen a flying UFO? I thought they only exist in fiction.

• Have you seen my dog? I am looking for him for the past hour!

• Have you ever seen my dog? He's really cute!

Which one is correct, “It's seems to be” or “It seems to be”?

 “It seems to be” is correct. This is immediately clear if you consider what “It’s” means in the other choice. “It’s” is a contraction of “It is”. Using this in the first sentence would result in “It is seems to be” which is obviously incorrect. So the correct sentence is, “It seems to be”.

It's vs It

 

it VS. this Vs. that

 It seems that it depends on context. If we are around with the ability to point on the object, meaning that we see it, then we can use "this" or "that" depends on the distance. But if we don't see it at all, we use "it".

"I came home" vs "I went home."

 It depends on where home is relative to where you are speaking.

If you are at home when you say this, you normally use "I came home" but if you are not at home, you say "I went home".
