We use the present progressive for events that are happening right now or that are temporary.
I am sitting in a chair. (right now)
I am studying English these days. (temporary)
My brother works in a hospital.
(he has been working there for a while, and will probably work there for a long time)
My brother is working in McDonalds.
(he is working there these days, but doesn’t plan to work there for very long)
Right： Tim and I are going to a movie tonight。
If you take Tim out of the sentence， “you” are the subject。 You are going to a movie。 When you‘re going to a movie， what do you say？
“I am going to a movie。”
You wouldn‘t say， “Me am going to a movie。”
你不会说，Me am going to a movie。
When you add Tim， the sentence construction remains the same。 You‘re simply adding Tim， and it’s correct to say the other person‘s name first。
“Tim and I are going to a movie。”
Your test is always to take the other person out of the sentence， decide on “I” or “me，” and then put the other person back in。
2.We Was， We Were
“Am， are， was， and were” are all parts of the powerful little verb， “to be。”
Am， are， was， and were都属于简短但大有效果的be动词。
What trips people up with this mighty little verb is present tense and past tense。 If something is happening now， it‘s present tense。 If it already happened， it’s past tense。
Singular and plural also becomes a problem。 Compare the following：
We （Tim and I） “are” going to a movie。 （present tense， plural）
I “am” going to a movie。 （present tense， singular）
We （Tim and I） “were” going to a movie。 （past tense， plural）
I “was” going to a movie。 （past tense， singular）
Can you hear the difference？
It is never correct to say， “We was。。。”
Why？ Because we is plural。 We always “were”。。。
